COMMANDS         top

   add
       hg add [OPTION]... [FILE]...
       Schedule files to be version controlled and added to the repository.
       The files will be added to the repository at the next commit. To undo
       an add before that, see hg forget.
       If no names are given, add all files to the repository.
       An example showing how new (unknown) files are added automatically by
       hg add:
       $ ls
       foo.c
       $ hg status
       ? foo.c
       $ hg add
       adding foo.c
       $ hg status
       A foo.c
       Returns 0 if all files are successfully added.
       Options:
       -I, --include
              include names matching the given patterns
       -X, --exclude
              exclude names matching the given patterns
       -S, --subrepos
              recurse into subrepositories
       -n, --dry-run
              do not perform actions, just print output
   addremove
       hg addremove [OPTION]... [FILE]...
       Add all new files and remove all missing files from the repository.
       New files are ignored if they match any of the patterns in .hgignore.
       As with add, these changes take effect at the next commit.
       Use the -s/--similarity option to detect renamed files. This option
       takes a percentage between 0 (disabled) and 100 (files must be
       identical) as its parameter. With a parameter greater than 0, this
       compares every removed file with every added file and records those
       similar enough as renames. Detecting renamed files this way can be
       expensive. After using this option, hg status -C can be used to check
       which files were identified as moved or renamed. If not specified,
       -s/--similarity defaults to 100 and only renames of identical files
       are detected.
       Returns 0 if all files are successfully added.
       Options:
       -s, --similarity
              guess renamed files by similarity (0<=s<=100)
       -I, --include
              include names matching the given patterns
       -X, --exclude
              exclude names matching the given patterns
       -n, --dry-run
              do not perform actions, just print output
   annotate
       hg annotate [-r REV] [-f] [-a] [-u] [-d] [-n] [-c] [-l] FILE...
       List changes in files, showing the revision id responsible for each
       line
       This command is useful for discovering when a change was made and by
       whom.
       Without the -a/--text option, annotate will avoid processing files it
       detects as binary. With -a, annotate will annotate the file anyway,
       although the results will probably be neither useful nor desirable.
       Returns 0 on success.
       Options:
       -r, --rev
              annotate the specified revision
       --follow
              follow copies/renames and list the filename (DEPRECATED)
       --no-follow
              don't follow copies and renames
       -a, --text
              treat all files as text
       -u, --user
              list the author (long with -v)
       -f, --file
              list the filename
       -d, --date
              list the date (short with -q)
       -n, --number
              list the revision number (default)
       -c, --changeset
              list the changeset
       -l, --line-number
              show line number at the first appearance
       -w, --ignore-all-space
              ignore white space when comparing lines
       -b, --ignore-space-change
              ignore changes in the amount of white space
       -B, --ignore-blank-lines
              ignore changes whose lines are all blank
       -I, --include
              include names matching the given patterns
       -X, --exclude
              exclude names matching the given patterns
              aliases: blame
   archive
       hg archive [OPTION]... DEST
       By default, the revision used is the parent of the working directory;
       use -r/--rev to specify a different revision.
       The archive type is automatically detected based on file extension
       (or override using -t/--type).
       Examples:
       · create a zip file containing the 1.0 release:
         hg archive -r 1.0 project-1.0.zip
       · create a tarball excluding .hg files:
         hg archive project.tar.gz -X ".hg*"
       Valid types are:
       files
              a directory full of files (default)
       tar
              tar archive, uncompressed
       tbz2
              tar archive, compressed using bzip2
       tgz
              tar archive, compressed using gzip
       uzip
              zip archive, uncompressed
       zip
              zip archive, compressed using deflate
       The exact name of the destination archive or directory is given using
       a format string; see hg help export for details.
       Each member added to an archive file has a directory prefix
       prepended. Use -p/--prefix to specify a format string for the prefix.
       The default is the basename of the archive, with suffixes removed.
       Returns 0 on success.
       Options:
       --no-decode
              do not pass files through decoders
       -p, --prefix
              directory prefix for files in archive
       -r, --rev
              revision to distribute
       -t, --type
              type of distribution to create
       -S, --subrepos
              recurse into subrepositories
       -I, --include
              include names matching the given patterns
       -X, --exclude
              exclude names matching the given patterns
   backout
       hg backout [OPTION]... [-r] REV
       Prepare a new changeset with the effect of REV undone in the current
       working directory.
       If REV is the parent of the working directory, then this new
       changeset is committed automatically. Otherwise, hg needs to merge
       the changes and the merged result is left uncommitted.
       Note   backout cannot be used to fix either an unwanted or incorrect
              merge.
       By default, the pending changeset will have one parent, maintaining a
       linear history. With --merge, the pending changeset will instead have
       two parents: the old parent of the working directory and a new child
       of REV that simply undoes REV.
       Before version 1.7, the behavior without --merge was equivalent to
       specifying --merge followed by hg update --clean . to cancel the
       merge and leave the child of REV as a head to be merged separately.
       See hg help dates for a list of formats valid for -d/--date.
       Returns 0 on success.
       Options:
       --merge
              merge with old dirstate parent after backout
       --parent
              parent to choose when backing out merge (DEPRECATED)
       -r, --rev
              revision to backout
       -t, --tool
              specify merge tool
       -I, --include
              include names matching the given patterns
       -X, --exclude
              exclude names matching the given patterns
       -m, --message
              use text as commit message
       -l, --logfile
              read commit message from file
       -d, --date
              record the specified date as commit date
       -u, --user
              record the specified user as committer
   bisect
       hg bisect [-gbsr] [-U] [-c CMD] [REV]
       This command helps to find changesets which introduce problems. To
       use, mark the earliest changeset you know exhibits the problem as
       bad, then mark the latest changeset which is free from the problem as
       good. Bisect will update your working directory to a revision for
       testing (unless the -U/--noupdate option is specified). Once you have
       performed tests, mark the working directory as good or bad, and
       bisect will either update to another candidate changeset or announce
       that it has found the bad revision.
       As a shortcut, you can also use the revision argument to mark a
       revision as good or bad without checking it out first.
       If you supply a command, it will be used for automatic bisection.
       The environment variable HG_NODE will contain the ID of the changeset
       being tested. The exit status of the command will be used to mark
       revisions as good or bad: status 0 means good, 125 means to skip the
       revision, 127 (command not found) will abort the bisection, and any
       other non-zero exit status means the revision is bad.
       Some examples:
       · start a bisection with known bad revision 12, and good revision 34:
         hg bisect --bad 34
         hg bisect --good 12
       · advance the current bisection by marking current revision as good
         or bad:
         hg bisect --good
         hg bisect --bad
       · mark the current revision, or a known revision, to be skipped (e.g.
         if that revision is not usable because of another issue):
         hg bisect --skip
         hg bisect --skip 23
       · skip all revisions that do not touch directories foo or bar
            hg bisect --skip '!( file("path:foo") & file("path:bar") )'
       · forget the current bisection:
         hg bisect --reset
       · use 'make && make tests' to automatically find the first broken
         revision:
         hg bisect --reset
         hg bisect --bad 34
         hg bisect --good 12
         hg bisect --command 'make && make tests'
       · see all changesets whose states are already known in the current
         bisection:
         hg log -r "bisect(pruned)"
       · see the changeset currently being bisected (especially useful if
         running with -U/--noupdate):
         hg log -r "bisect(current)"
       · see all changesets that took part in the current bisection:
         hg log -r "bisect(range)"
       · with the graphlog extension, you can even get a nice graph:
         hg log --graph -r "bisect(range)"
       See hg help revsets for more about the bisect() keyword.
       Returns 0 on success.
       Options:
       -r, --reset
              reset bisect state
       -g, --good
              mark changeset good
       -b, --bad
              mark changeset bad
       -s, --skip
              skip testing changeset
       -e, --extend
              extend the bisect range
       -c, --command
              use command to check changeset state
       -U, --noupdate
              do not update to target
   bookmarks
       hg bookmarks [OPTIONS]... [NAME]...
       Bookmarks are pointers to certain commits that move when committing.
       Bookmarks are local. They can be renamed, copied and deleted. It is
       possible to use hg merge NAME to merge from a given bookmark, and hg
       update NAME to update to a given bookmark.
       You can use hg bookmark NAME to set a bookmark on the working
       directory's parent revision with the given name. If you specify a
       revision using -r REV (where REV may be an existing bookmark), the
       bookmark is assigned to that revision.
       Bookmarks can be pushed and pulled between repositories (see hg help
       push and hg help pull). This requires both the local and remote
       repositories to support bookmarks. For versions prior to 1.8, this
       means the bookmarks extension must be enabled.
       If you set a bookmark called '@', new clones of the repository will
       have that revision checked out (and the bookmark made active) by
       default.
       With -i/--inactive, the new bookmark will not be made the active
       bookmark. If -r/--rev is given, the new bookmark will not be made
       active even if -i/--inactive is not given. If no NAME is given, the
       current active bookmark will be marked inactive.
       Options:
       -f, --force
              force
       -r, --rev
              revision
       -d, --delete
              delete a given bookmark
       -m, --rename
              rename a given bookmark
       -i, --inactive
              mark a bookmark inactive
              aliases: bookmark
   branch
       hg branch [-fC] [NAME]
       Note   Branch names are permanent and global. Use hg bookmark to
              create a light-weight bookmark instead. See hg help glossary
              for more information about named branches and bookmarks.
       With no argument, show the current branch name. With one argument,
       set the working directory branch name (the branch will not exist in
       the repository until the next commit). Standard practice recommends
       that primary development take place on the 'default' branch.
       Unless -f/--force is specified, branch will not let you set a branch
       name that already exists, even if it's inactive.
       Use -C/--clean to reset the working directory branch to that of the
       parent of the working directory, negating a previous branch change.
       Use the command hg update to switch to an existing branch. Use hg
       commit --close-branch to mark this branch as closed.
       Returns 0 on success.
       Options:
       -f, --force
              set branch name even if it shadows an existing branch
       -C, --clean
              reset branch name to parent branch name
   branches
       hg branches [-ac]
       List the repository's named branches, indicating which ones are
       inactive. If -c/--closed is specified, also list branches which have
       been marked closed (see hg commit --close-branch).
       If -a/--active is specified, only show active branches. A branch is
       considered active if it contains repository heads.
       Use the command hg update to switch to an existing branch.
       Returns 0.
       Options:
       -a, --active
              show only branches that have unmerged heads
       -c, --closed
              show normal and closed branches
   bundle
       hg bundle [-f] [-t TYPE] [-a] [-r REV]... [--base REV]... FILE [DEST]
       Generate a compressed changegroup file collecting changesets not
       known to be in another repository.
       If you omit the destination repository, then hg assumes the
       destination will have all the nodes you specify with --base
       parameters. To create a bundle containing all changesets, use
       -a/--all (or --base null).
       You can change compression method with the -t/--type option.  The
       available compression methods are: none, bzip2, and gzip (by default,
       bundles are compressed using bzip2).
       The bundle file can then be transferred using conventional means and
       applied to another repository with the unbundle or pull command. This
       is useful when direct push and pull are not available or when
       exporting an entire repository is undesirable.
       Applying bundles preserves all changeset contents including
       permissions, copy/rename information, and revision history.
       Returns 0 on success, 1 if no changes found.
       Options:
       -f, --force
              run even when the destination is unrelated
       -r, --rev
              a changeset intended to be added to the destination
       -b, --branch
              a specific branch you would like to bundle
       --base a base changeset assumed to be available at the destination
       -a, --all
              bundle all changesets in the repository
       -t, --type
              bundle compression type to use (default: bzip2)
       -e, --ssh
              specify ssh command to use
       --remotecmd
              specify hg command to run on the remote side
       --insecure
              do not verify server certificate (ignoring web.cacerts config)
   cat
       hg cat [OPTION]... FILE...
       Print the specified files as they were at the given revision. If no
       revision is given, the parent of the working directory is used, or
       tip if no revision is checked out.
       Output may be to a file, in which case the name of the file is given
       using a format string. The formatting rules are the same as for the
       export command, with the following additions:
       %s
              basename of file being printed
       %d
              dirname of file being printed, or '.' if in repository root
       %p
              root-relative path name of file being printed
       Returns 0 on success.
       Options:
       -o, --output
              print output to file with formatted name
       -r, --rev
              print the given revision
       --decode
              apply any matching decode filter
       -I, --include
              include names matching the given patterns
       -X, --exclude
              exclude names matching the given patterns
   clone
       hg clone [OPTION]... SOURCE [DEST]
       Create a copy of an existing repository in a new directory.
       If no destination directory name is specified, it defaults to the
       basename of the source.
       The location of the source is added to the new repository's .hg/hgrc
       file, as the default to be used for future pulls.
       Only local paths and ssh:// URLs are supported as destinations. For
       ssh:// destinations, no working directory or .hg/hgrc will be created
       on the remote side.
       To pull only a subset of changesets, specify one or more revisions
       identifiers with -r/--rev or branches with -b/--branch. The resulting
       clone will contain only the specified changesets and their ancestors.
       These options (or 'clone src#rev dest') imply --pull, even for local
       source repositories. Note that specifying a tag will include the
       tagged changeset but not the changeset containing the tag.
       If the source repository has a bookmark called '@' set, that revision
       will be checked out in the new repository by default.
       To check out a particular version, use -u/--update, or -U/--noupdate
       to create a clone with no working directory.
       For efficiency, hardlinks are used for cloning whenever the source
       and destination are on the same filesystem (note this applies only to
       the repository data, not to the working directory). Some filesystems,
       such as AFS, implement hardlinking incorrectly, but do not report
       errors. In these cases, use the --pull option to avoid hardlinking.
       In some cases, you can clone repositories and the working directory
       using full hardlinks with
       $ cp -al REPO REPOCLONE
       This is the fastest way to clone, but it is not always safe. The
       operation is not atomic (making sure REPO is not modified during the
       operation is up to you) and you have to make sure your editor breaks
       hardlinks (Emacs and most Linux Kernel tools do so). Also, this is
       not compatible with certain extensions that place their metadata
       under the .hg directory, such as mq.
       Mercurial will update the working directory to the first applicable
       revision from this list:
       a. null if -U or the source repository has no changesets
       b. if -u . and the source repository is local, the first parent of
          the source repository's working directory
       c. the changeset specified with -u (if a branch name, this means the
          latest head of that branch)
       d. the changeset specified with -r
       e. the tipmost head specified with -b
       f. the tipmost head specified with the url#branch source syntax
       g. the revision marked with the '@' bookmark, if present
       h. the tipmost head of the default branch
       i. tip
       Examples:
       · clone a remote repository to a new directory named hg/:
         hg clone http://selenic.com/hg
       · create a lightweight local clone:
         hg clone project/ project-feature/
       · clone from an absolute path on an ssh server (note double-slash):
         hg clone ssh://user@server//home/projects/alpha/
       · do a high-speed clone over a LAN while checking out a specified
         version:
         hg clone --uncompressed http://server/repo -u 1.5
       · create a repository without changesets after a particular revision:
         hg clone -r 04e544 experimental/ good/
       · clone (and track) a particular named branch:
         hg clone http://selenic.com/hg#stable
       See hg help urls for details on specifying URLs.
       Returns 0 on success.
       Options:
       -U, --noupdate
              the clone will include an empty working copy (only a
              repository)
       -u, --updaterev
              revision, tag or branch to check out
       -r, --rev
              include the specified changeset
       -b, --branch
              clone only the specified branch
       --pull use pull protocol to copy metadata
       --uncompressed
              use uncompressed transfer (fast over LAN)
       -e, --ssh
              specify ssh command to use
       --remotecmd
              specify hg command to run on the remote side
       --insecure
              do not verify server certificate (ignoring web.cacerts config)
   commit
       hg commit [OPTION]... [FILE]...
       Commit changes to the given files into the repository. Unlike a
       centralized SCM, this operation is a local operation. See hg push for
       a way to actively distribute your changes.
       If a list of files is omitted, all changes reported by hg status will
       be committed.
       If you are committing the result of a merge, do not provide any
       filenames or -I/-X filters.
       If no commit message is specified, Mercurial starts your configured
       editor where you can enter a message. In case your commit fails, you
       will find a backup of your message in .hg/last-message.txt.
       The --amend flag can be used to amend the parent of the working
       directory with a new commit that contains the changes in the parent
       in addition to those currently reported by hg status, if there are
       any. The old commit is stored in a backup bundle in .hg/strip-backup
       (see hg help bundle and hg help unbundle on how to restore it).
       Message, user and date are taken from the amended commit unless
       specified. When a message isn't specified on the command line, the
       editor will open with the message of the amended commit.
       It is not possible to amend public changesets (see hg help phases) or
       changesets that have children.
       See hg help dates for a list of formats valid for -d/--date.
       Returns 0 on success, 1 if nothing changed.
       Options:
       -A, --addremove
              mark new/missing files as added/removed before committing
       --close-branch
              mark a branch as closed, hiding it from the branch list
       --amend
              amend the parent of the working dir
       -I, --include
              include names matching the given patterns
       -X, --exclude
              exclude names matching the given patterns
       -m, --message
              use text as commit message
       -l, --logfile
              read commit message from file
       -d, --date
              record the specified date as commit date
       -u, --user
              record the specified user as committer
       -S, --subrepos
              recurse into subrepositories
              aliases: ci
   copy
       hg copy [OPTION]... [SOURCE]... DEST
       Mark dest as having copies of source files. If dest is a directory,
       copies are put in that directory. If dest is a file, the source must
       be a single file.
       By default, this command copies the contents of files as they exist
       in the working directory. If invoked with -A/--after, the operation
       is recorded, but no copying is performed.
       This command takes effect with the next commit. To undo a copy before
       that, see hg revert.
       Returns 0 on success, 1 if errors are encountered.
       Options:
       -A, --after
              record a copy that has already occurred
       -f, --force
              forcibly copy over an existing managed file
       -I, --include
              include names matching the given patterns
       -X, --exclude
              exclude names matching the given patterns
       -n, --dry-run
              do not perform actions, just print output
              aliases: cp
   diff
       hg diff [OPTION]... ([-c REV] | [-r REV1 [-r REV2]]) [FILE]...
       Show differences between revisions for the specified files.
       Differences between files are shown using the unified diff format.
       Note   diff may generate unexpected results for merges, as it will
              default to comparing against the working directory's first
              parent changeset if no revisions are specified.
       When two revision arguments are given, then changes are shown between
       those revisions. If only one revision is specified then that revision
       is compared to the working directory, and, when no revisions are
       specified, the working directory files are compared to its parent.
       Alternatively you can specify -c/--change with a revision to see the
       changes in that changeset relative to its first parent.
       Without the -a/--text option, diff will avoid generating diffs of
       files it detects as binary. With -a, diff will generate a diff
       anyway, probably with undesirable results.
       Use the -g/--git option to generate diffs in the git extended diff
       format. For more information, read hg help diffs.
       Examples:
       · compare a file in the current working directory to its parent:
         hg diff foo.c
       · compare two historical versions of a directory, with rename info:
         hg diff --git -r 1.0:1.2 lib/
       · get change stats relative to the last change on some date:
         hg diff --stat -r "date('may 2')"
       · diff all newly-added files that contain a keyword:
         hg diff "set:added() and grep(GNU)"
       · compare a revision and its parents:
         hg diff -c 9353         # compare against first parent
         hg diff -r 9353^:9353   # same using revset syntax
         hg diff -r 9353^2:9353  # compare against the second parent
       Returns 0 on success.
       Options:
       -r, --rev
              revision
       -c, --change
              change made by revision
       -a, --text
              treat all files as text
       -g, --git
              use git extended diff format
       --nodates
              omit dates from diff headers
       -p, --show-function
              show which function each change is in
       --reverse
              produce a diff that undoes the changes
       -w, --ignore-all-space
              ignore white space when comparing lines
       -b, --ignore-space-change
              ignore changes in the amount of white space
       -B, --ignore-blank-lines
              ignore changes whose lines are all blank
       -U, --unified
              number of lines of context to show
       --stat output diffstat-style summary of changes
       -I, --include
              include names matching the given patterns
       -X, --exclude
              exclude names matching the given patterns
       -S, --subrepos
              recurse into subrepositories
   export
       hg export [OPTION]... [-o OUTFILESPEC] [-r] [REV]...
       Print the changeset header and diffs for one or more revisions.  If
       no revision is given, the parent of the working directory is used.
       The information shown in the changeset header is: author, date,
       branch name (if non-default), changeset hash, parent(s) and commit
       comment.
       Note   export may generate unexpected diff output for merge
              changesets, as it will compare the merge changeset against its
              first parent only.
       Output may be to a file, in which case the name of the file is given
       using a format string. The formatting rules are as follows:
       %%
              literal "%" character
       %H
              changeset hash (40 hexadecimal digits)
       %N
              number of patches being generated
       %R
              changeset revision number
       %b
              basename of the exporting repository
       %h
              short-form changeset hash (12 hexadecimal digits)
       %m
              first line of the commit message (only alphanumeric
              characters)
       %n
              zero-padded sequence number, starting at 1
       %r
              zero-padded changeset revision number
       Without the -a/--text option, export will avoid generating diffs of
       files it detects as binary. With -a, export will generate a diff
       anyway, probably with undesirable results.
       Use the -g/--git option to generate diffs in the git extended diff
       format. See hg help diffs for more information.
       With the --switch-parent option, the diff will be against the second
       parent. It can be useful to review a merge.
       Examples:
       · use export and import to transplant a bugfix to the current branch:
         hg export -r 9353 | hg import -
       · export all the changesets between two revisions to a file with
         rename information:
         hg export --git -r 123:150 > changes.txt
       · split outgoing changes into a series of patches with descriptive
         names:
         hg export -r "outgoing()" -o "%n-%m.patch"
       Returns 0 on success.
       Options:
       -o, --output
              print output to file with formatted name
       --switch-parent
              diff against the second parent
       -r, --rev
              revisions to export
       -a, --text
              treat all files as text
       -g, --git
              use git extended diff format
       --nodates
              omit dates from diff headers
   forget
       hg forget [OPTION]... FILE...
       Mark the specified files so they will no longer be tracked after the
       next commit.
       This only removes files from the current branch, not from the entire
       project history, and it does not delete them from the working
       directory.
       To undo a forget before the next commit, see hg add.
       Examples:
       · forget newly-added binary files:
         hg forget "set:added() and binary()"
       · forget files that would be excluded by .hgignore:
         hg forget "set:hgignore()"
       Returns 0 on success.
       Options:
       -I, --include
              include names matching the given patterns
       -X, --exclude
              exclude names matching the given patterns
   graft
       hg graft [OPTION]... [-r] REV...
       This command uses Mercurial's merge logic to copy individual changes
       from other branches without merging branches in the history graph.
       This is sometimes known as 'backporting' or 'cherry-picking'. By
       default, graft will copy user, date, and description from the source
       changesets.
       Changesets that are ancestors of the current revision, that have
       already been grafted, or that are merges will be skipped.
       If --log is specified, log messages will have a comment appended of
       the form:
       (grafted from CHANGESETHASH)
       If a graft merge results in conflicts, the graft process is
       interrupted so that the current merge can be manually resolved.  Once
       all conflicts are addressed, the graft process can be continued with
       the -c/--continue option.
       Note   The -c/--continue option does not reapply earlier options.
       Examples:
       · copy a single change to the stable branch and edit its description:
         hg update stable
         hg graft --edit 9393
       · graft a range of changesets with one exception, updating dates:
         hg graft -D "2085::2093 and not 2091"
       · continue a graft after resolving conflicts:
         hg graft -c
       · show the source of a grafted changeset:
         hg log --debug -r tip
       Returns 0 on successful completion.
       Options:
       -r, --rev
              revisions to graft
       -c, --continue
              resume interrupted graft
       -e, --edit
              invoke editor on commit messages
       --log  append graft info to log message
       -D, --currentdate
              record the current date as commit date
       -U, --currentuser
              record the current user as committer
       -d, --date
              record the specified date as commit date
       -u, --user
              record the specified user as committer
       -t, --tool
              specify merge tool
       -n, --dry-run
              do not perform actions, just print output
   grep
       hg grep [OPTION]... PATTERN [FILE]...
       Search revisions of files for a regular expression.
       This command behaves differently than Unix grep. It only accepts
       Python/Perl regexps. It searches repository history, not the working
       directory. It always prints the revision number in which a match
       appears.
       By default, grep only prints output for the first revision of a file
       in which it finds a match. To get it to print every revision that
       contains a change in match status ("-" for a match that becomes a
       non-match, or "+" for a non-match that becomes a match), use the
       --all flag.
       Returns 0 if a match is found, 1 otherwise.
       Options:
       -0, --print0
              end fields with NUL
       --all  print all revisions that match
       -a, --text
              treat all files as text
       -f, --follow
              follow changeset history, or file history across copies and
              renames
       -i, --ignore-case
              ignore case when matching
       -l, --files-with-matches
              print only filenames and revisions that match
       -n, --line-number
              print matching line numbers
       -r, --rev
              only search files changed within revision range
       -u, --user
              list the author (long with -v)
       -d, --date
              list the date (short with -q)
       -I, --include
              include names matching the given patterns
       -X, --exclude
              exclude names matching the given patterns
   heads
       hg heads [-ct] [-r STARTREV] [REV]...
       With no arguments, show all repository branch heads.
       Repository "heads" are changesets with no child changesets. They are
       where development generally takes place and are the usual targets for
       update and merge operations. Branch heads are changesets that have no
       child changeset on the same branch.
       If one or more REVs are given, only branch heads on the branches
       associated with the specified changesets are shown. This means that
       you can use hg heads foo to see the heads on a branch named foo.
       If -c/--closed is specified, also show branch heads marked closed
       (see hg commit --close-branch).
       If STARTREV is specified, only those heads that are descendants of
       STARTREV will be displayed.
       If -t/--topo is specified, named branch mechanics will be ignored and
       only changesets without children will be shown.
       Returns 0 if matching heads are found, 1 if not.
       Options:
       -r, --rev
              show only heads which are descendants of STARTREV
       -t, --topo
              show topological heads only
       -a, --active
              show active branchheads only (DEPRECATED)
       -c, --closed
              show normal and closed branch heads
       --style
              display using template map file
       --template
              display with template
   help
       hg help [-ec] [TOPIC]
       With no arguments, print a list of commands with short help messages.
       Given a topic, extension, or command name, print help for that topic.
       Returns 0 if successful.
       Options:
       -e, --extension
              show only help for extensions
       -c, --command
              show only help for commands
       -k, --keyword
              show topics matching keyword
   identify
       hg identify [-nibtB] [-r REV] [SOURCE]
       Print a summary identifying the repository state at REV using one or
       two parent hash identifiers, followed by a "+" if the working
       directory has uncommitted changes, the branch name (if not default),
       a list of tags, and a list of bookmarks.
       When REV is not given, print a summary of the current state of the
       repository.
       Specifying a path to a repository root or Mercurial bundle will cause
       lookup to operate on that repository/bundle.
       Examples:
       · generate a build identifier for the working directory:
         hg id --id > build-id.dat
       · find the revision corresponding to a tag:
         hg id -n -r 1.3
       · check the most recent revision of a remote repository:
         hg id -r tip http://selenic.com/hg/
       Returns 0 if successful.
       Options:
       -r, --rev
              identify the specified revision
       -n, --num
              show local revision number
       -i, --id
              show global revision id
       -b, --branch
              show branch
       -t, --tags
              show tags
       -B, --bookmarks
              show bookmarks
       -e, --ssh
              specify ssh command to use
       --remotecmd
              specify hg command to run on the remote side
       --insecure
              do not verify server certificate (ignoring web.cacerts config)
              aliases: id
   import
       hg import [OPTION]... PATCH...
       Import a list of patches and commit them individually (unless
       --no-commit is specified).
       If there are outstanding changes in the working directory, import
       will abort unless given the -f/--force flag.
       You can import a patch straight from a mail message. Even patches as
       attachments work (to use the body part, it must have type text/plain
       or text/x-patch). From and Subject headers of email message are used
       as default committer and commit message. All text/plain body parts
       before first diff are added to commit message.
       If the imported patch was generated by hg export, user and
       description from patch override values from message headers and body.
       Values given on command line with -m/--message and -u/--user override
       these.
       If --exact is specified, import will set the working directory to the
       parent of each patch before applying it, and will abort if the
       resulting changeset has a different ID than the one recorded in the
       patch. This may happen due to character set problems or other
       deficiencies in the text patch format.
       Use --bypass to apply and commit patches directly to the repository,
       not touching the working directory. Without --exact, patches will be
       applied on top of the working directory parent revision.
       With -s/--similarity, hg will attempt to discover renames and copies
       in the patch in the same way as hg addremove.
       To read a patch from standard input, use "-" as the patch name. If a
       URL is specified, the patch will be downloaded from it.  See hg help
       dates for a list of formats valid for -d/--date.
       Examples:
       · import a traditional patch from a website and detect renames:
         hg import -s 80 http://example.com/bugfix.patch
       · import a changeset from an hgweb server:
         hg import http://www.selenic.com/hg/rev/5ca8c111e9aa
       · import all the patches in an Unix-style mbox:
         hg import incoming-patches.mbox
       · attempt to exactly restore an exported changeset (not always
         possible):
         hg import --exact proposed-fix.patch
       Returns 0 on success.
       Options:
       -p, --strip
              directory strip option for patch. This has the same meaning as
              the corresponding patch option (default: 1)
       -b, --base
              base path (DEPRECATED)
       -e, --edit
              invoke editor on commit messages
       -f, --force
              skip check for outstanding uncommitted changes
       --no-commit
              don't commit, just update the working directory
       --bypass
              apply patch without touching the working directory
       --exact
              apply patch to the nodes from which it was generated
       --import-branch
              use any branch information in patch (implied by --exact)
       -m, --message
              use text as commit message
       -l, --logfile
              read commit message from file

              aliases: patch
   incoming
       hg incoming [-p] [-n] [-M] [-f] [-r REV]... [--bundle FILENAME] [SOURCE]
       Show new changesets found in the specified path/URL or the default
       pull location. These are the changesets that would have been pulled
       if a pull at the time you issued this command.
       For remote repository, using --bundle avoids downloading the
       changesets twice if the incoming is followed by a pull.
       See pull for valid source format details.
       Returns 0 if there are incoming changes, 1 otherwise.
       Options:
       -f, --force
              run even if remote repository is unrelated
       -n, --newest-first
              show newest record first
       --bundle
              file to store the bundles into
       -r, --rev

       --template
              display with template
       -e, --ssh
              specify ssh command to use
       --remotecmd
              specify hg command to run on the remote side
       --insecure
              do not verify server certificate (ignoring web.cacerts config)
       -S, --subrepos
              recurse into subrepositories
              aliases: in
   init
       hg init [-e CMD] [--remotecmd CMD] [DEST]
       Initialize a new repository in the given directory. If the given
       directory does not exist, it will be created.
       If no directory is given, the current directory is used.
       It is possible to specify an ssh:// URL as the destination.  See hg
       help urls for more information.
       Returns 0 on success.
       Options:
       -e, --ssh
              specify ssh command to use
       --remotecmd
              specify hg command to run on the remote side
       --insecure
              do not verify server certificate (ignoring web.cacerts config)
   locate
       hg locate [OPTION]... [PATTERN]...
       Print files under Mercurial control in the working directory whose
       names match the given patterns.
       By default, this command searches all directories in the working
       directory. To search just the current directory and its
       subdirectories, use "--include .".
       If no patterns are given to match, this command prints the names of
       all files under Mercurial control in the working directory.
       If you want to feed the output of this command into the "xargs"
       command, use the -0 option to both this command and "xargs". This
       will avoid the problem of "xargs" treating single filenames that
       contain whitespace as multiple filenames.
       Returns 0 if a match is found, 1 otherwise.
       Options:
       -r, --rev
              search the repository as it is in REV
       -0, --print0
              end filenames with NUL, for use with xargs
       -f, --fullpath
              print complete paths from the filesystem root
       -I, --include
              include names matching the given patterns
       -X, --exclude
              exclude names matching the given patterns
   log
       hg log [OPTION]... [FILE]
       Print the revision history of the specified files or the entire
       project.
       If no revision range is specified, the default is tip:0 unless
       --follow is set, in which case the working directory parent is used
       as the starting revision.
       File history is shown without following rename or copy history of
       files. Use -f/--follow with a filename to follow history across
       renames and copies. --follow without a filename will only show
       ancestors or descendants of the starting revision.
       By default this command prints revision number and changeset id,
       tags, non-trivial parents, user, date and time, and a summary for
       each commit. When the -v/--verbose switch is used, the list of
       changed files and full commit message are shown.
       Note   log -p/--patch may generate unexpected diff output for merge
              changesets, as it will only compare the merge changeset
              against its first parent. Also, only files different from BOTH
              parents will appear in files:.
       Note   for performance reasons, log FILE may omit duplicate changes
              made on branches and will not show deletions. To see all
              changes including duplicates and deletions, use the --removed
              switch.
       Some examples:
       · changesets with full descriptions and file lists:
         hg log -v
       · changesets ancestral to the working directory:
         hg log -f
       · last 10 commits on the current branch:
         hg log -l 10 -b .
       · changesets showing all modifications of a file, including removals:
         hg log --removed file.c
       · all changesets that touch a directory, with diffs, excluding
         merges:
         hg log -Mp lib/
       · all revision numbers that match a keyword:
         hg log -k bug --template "{rev}\n"
       · check if a given changeset is included is a tagged release:
         hg log -r "a21ccf and ancestor(1.9)"
       · find all changesets by some user in a date range:
         hg log -k alice -d "may 2008 to jul 2008"
       · summary of all changesets after the last tag:
         hg log -r "last(tagged())::" --template "{desc|firstline}\n"

              aliases: history
   manifest
       hg manifest [-r REV]
       Print a list of version controlled files for the given revision.  If
       no revision is given, the first parent of the working directory is
       used, or the null revision if no revision is checked out.
       With -v, print file permissions, symlink and executable bits.  With
       --debug, print file revision hashes.
       If option --all is specified, the list of all files from all
       revisions is printed. This includes deleted and renamed files.
       Returns 0 on success.
       Options:
       -r, --rev
              revision to display
       --all  list files from all revisions
   merge
       hg merge [-P] [-f] [[-r] REV]
       The current working directory is updated with all changes made in the
       requested revision since the last common predecessor revision.
       Files that changed between either parent are marked as changed for
       the next commit and a commit must be performed before any further
       updates to the repository are allowed. The next commit will have two
       parents.
       --tool can be used to specify the merge tool used for file merges. It
       overrides the HGMERGE environment variable and your configuration
       files. See hg help merge-tools for options.
       If no revision is specified, the working directory's parent is a head
       revision, and the current branch contains exactly one other head, the
       other head is merged with by default. Otherwise, an explicit revision
       with which to merge with must be provided.
       hg resolve must be used to resolve unresolved files.
       To undo an uncommitted merge, use hg update --clean . which will
       check out a clean copy of the original merge parent, losing all
       changes.
       Returns 0 on success, 1 if there are unresolved files.
       Options:
       -f, --force
              force a merge with outstanding changes
       -r, --rev
              revision to merge

              specify merge tool
   outgoing
       hg outgoing [-M] [-p] [-n] [-f] [-r REV]... [DEST]
       Show changesets not found in the specified destination repository or
       the default push location. These are the changesets that would be
       pushed if a push was requested.
       See pull for details of valid destination formats.
       Returns 0 if there are outgoing changes, 1 otherwise.
       Options:
       -f, --force
              run even when the destination is unrelated
       -r, --rev
              a changeset intended to be included in the destination

              aliases: out
   parents
       hg parents [-r REV] [FILE]
       Print the working directory's parent revisions. If a revision is
       given via -r/--rev, the parent of that revision will be printed.  If
       a file argument is given, the revision in which the file was last
       changed (before the working directory revision or the argument to
       --rev if given) is printed.
       Returns 0 on success.
       Options:
       -r, --rev
              show parents of the specified revision
       --style
              display using template map file
       --template
              display with template
   paths
       hg paths [NAME]
       Show definition of symbolic path name NAME. If no name is given, show
       definition of all available names.
       Option -q/--quiet suppresses all output when searching for NAME and
       shows only the path names when listing all definitions.
       Path names are defined in the [paths] section of your configuration
       file and in /etc/mercurial/hgrc. If run inside a repository, .hg/hgrc
       is used, too.
       The path names default and default-push have a special meaning.  When
       performing a push or pull operation, they are used as fallbacks if no
       location is specified on the command-line.  When default-push is set,
       it will be used for push and default will be used for pull; otherwise
       default is used as the fallback for both.  When cloning a repository,
       the clone source is written as default in .hg/hgrc.  Note that
       default and default-push apply to all inbound (e.g.  hg incoming) and
       outbound (e.g. hg outgoing, hg email and hg bundle) operations.
       See hg help urls for more information.
       Returns 0 on success.
   phase
       hg phase [-p|-d|-s] [-f] [-r] REV...
       With no argument, show the phase name of specified revisions.
       With one of -p/--public, -d/--draft or -s/--secret, change the phase
       value of the specified revisions.
       Unless -f/--force is specified, hg phase won't move changeset from a
       lower phase to an higher phase. Phases are ordered as follows:
       public < draft < secret
       Return 0 on success, 1 if no phases were changed or some could not be
       changed.
       Options:
       -p, --public
              set changeset phase to public
       -d, --draft
              set changeset phase to draft
       -s, --secret
              set changeset phase to secret
       -f, --force
              allow to move boundary backward
       -r, --rev
              target revision
   pull
       hg pull [-u] [-f] [-r REV]... [-e CMD] [--remotecmd CMD] [SOURCE]
       Pull changes from a remote repository to a local one.
       This finds all changes from the repository at the specified path or
       URL and adds them to a local repository (the current one unless -R is
       specified). By default, this does not update the copy of the project
       in the working directory.
       Use hg incoming if you want to see what would have been added by a
       pull at the time you issued this command. If you then decide to add
       those changes to the repository, you should use hg pull -r X where X
       is the last changeset listed by hg incoming.
       If SOURCE is omitted, the 'default' path will be used.  See hg help
       urls for more information.
       Returns 0 on success, 1 if an update had unresolved files.
       Options:
       -u, --update
              update to new branch head if changesets were pulled
       -f, --force
              run even when remote repository is unrelated
       -r, --rev
              a remote changeset intended to be added
       -B, --bookmark
              bookmark to pull
       -b, --branch
              a specific branch you would like to pull
       -e, --ssh
              specify ssh command to use
       --remotecmd
              specify hg command to run on the remote side
       --insecure
              do not verify server certificate (ignoring web.cacerts config)
   push
       hg push [-f] [-r REV]... [-e CMD] [--remotecmd CMD] [DEST]
       Push changesets from the local repository to the specified
       destination.
       This operation is symmetrical to pull: it is identical to a pull in
       the destination repository from the current one.
       By default, push will not allow creation of new heads at the
       destination, since multiple heads would make it unclear which head to
       use. In this situation, it is recommended to pull and merge before
       pushing.
       Use --new-branch if you want to allow push to create a new named
       branch that is not present at the destination. This allows you to
       only create a new branch without forcing other changes.
       Use -f/--force to override the default behavior and push all
       changesets on all branches.
       If -r/--rev is used, the specified revision and all its ancestors
       will be pushed to the remote repository.
       If -B/--bookmark is used, the specified bookmarked revision, its
       ancestors, and the bookmark will be pushed to the remote repository.
       Please see hg help urls for important details about ssh:// URLs. If
       DESTINATION is omitted, a default path will be used.
       Returns 0 if push was successful, 1 if nothing to push.
       Options:
       -f, --force
              force push
       -r, --rev
              a changeset intended to be included in the destination
       -B, --bookmark
              bookmark to push
       -b, --branch
              a specific branch you would like to push
       --new-branch
              allow pushing a new branch
       -e, --ssh
              specify ssh command to use
       --remotecmd
              specify hg command to run on the remote side
       --insecure
              do not verify server certificate (ignoring web.cacerts config)
   recover
       hg recover
       Recover from an interrupted commit or pull.
       This command tries to fix the repository status after an interrupted
       operation. It should only be necessary when Mercurial suggests it.
       Returns 0 if successful, 1 if nothing to recover or verify fails.
   remove
       hg remove [OPTION]... FILE...
       Schedule the indicated files for removal from the current branch.
       This command schedules the files to be removed at the next commit.
       To undo a remove before that, see hg revert. To undo added files, see
       hg forget.
       -A/--after can be used to remove only files that have already been
       deleted, -f/--force can be used to force deletion, and -Af can be
       used to remove files from the next revision without deleting them
       from the working directory.
       The following table details the behavior of remove for different file
       states (columns) and option combinations (rows). The file states are
       Added [A], Clean [C], Modified [M] and Missing [!]  (as reported by
       hg status). The actions are Warn, Remove (from branch) and Delete
       (from disk):

       Note that remove never deletes files in Added [A] state from the
       working directory, not even if option --force is specified.
       Returns 0 on success, 1 if any warnings encountered.
       Options:
       -A, --after
              record delete for missing files
       -f, --force
              remove (and delete) file even if added or modified
       -I, --include
              include names matching the given patterns
       -X, --exclude
              exclude names matching the given patterns
              aliases: rm
   rename
       hg rename [OPTION]... SOURCE... DEST
       Mark dest as copies of sources; mark sources for deletion. If dest is
       a directory, copies are put in that directory. If dest is a file,
       there can only be one source.
       By default, this command copies the contents of files as they exist
       in the working directory. If invoked with -A/--after, the operation
       is recorded, but no copying is performed.
       This command takes effect at the next commit. To undo a rename before
       that, see hg revert.
       Returns 0 on success, 1 if errors are encountered.
       Options:
       -A, --after
              record a rename that has already occurred
       -f, --force

   resolve
       hg resolve [OPTION]... [FILE]...
       Merges with unresolved conflicts are often the result of
       non-interactive merging using the internal:merge configuration
       setting, or a command-line merge tool like diff3. The resolve command
       is used to manage the files involved in a merge, after hg merge has
       been run, and before hg commit is run (i.e. the working directory
       must have two parents). See hg help merge-tools for information on
       configuring merge tools.
       The resolve command can be used in the following ways:
       · hg resolve [--tool TOOL] FILE...: attempt to re-merge the specified
         files, discarding any previous merge attempts. Re-merging is not
         performed for files already marked as resolved. Use --all/-a to
         select all unresolved files. --tool can be used to specify the
         merge tool used for the given files. It overrides the HGMERGE
         environment variable and your configuration files.  Previous file
         contents are saved with a .orig suffix.
       · hg resolve -m [FILE]: mark a file as having been resolved (e.g.
         after having manually fixed-up the files). The default is to mark
         all unresolved files.
       · hg resolve -u [FILE]...: mark a file as unresolved. The default is
         to mark all resolved files.
       · hg resolve -l: list files which had or still have conflicts.  In
         the printed list, U = unresolved and R = resolved.
       Note that Mercurial will not let you commit files with unresolved
       merge conflicts. You must use hg resolve -m ... before you can commit
       after a conflicting merge.
       Returns 0 on success, 1 if any files fail a resolve attempt.
       Options:
       -a, --all
              select all unresolved files
       -l, --list
              list state of files needing merge
       -m, --mark
              mark files as resolved
       -u, --unmark
              mark files as unresolved
       -n, --no-status
              hide status prefix
       -t, --tool
              specify merge tool
       -I, --include
              include names matching the given patterns
       -X, --exclude
              exclude names matching the given patterns
   revert
       hg revert [OPTION]... [-r REV] [NAME]...
       Note   To check out earlier revisions, you should use hg update REV.
              To cancel an uncommitted merge (and lose your changes), use hg
              update --clean ..
       With no revision specified, revert the specified files or directories
       to the contents they had in the parent of the working directory.
       This restores the contents of files to an unmodified state and
       unschedules adds, removes, copies, and renames. If the working
       directory has two parents, you must explicitly specify a revision.
       Using the -r/--rev or -d/--date options, revert the given files or
       directories to their states as of a specific revision. Because revert
       does not change the working directory parents, this will cause these
       files to appear modified. This can be helpful to "back out" some or
       all of an earlier change. See hg backout for a related method.
       Modified files are saved with a .orig suffix before reverting.  To
       disable these backups, use --no-backup.
       See hg help dates for a list of formats valid for -d/--date.
       Returns 0 on success.
       Options:
       -a, --all
              revert all changes when no arguments given
       -d, --date
              tipmost revision matching date
       -r, --rev
              revert to the specified revision
       -C, --no-backup
              do not save backup copies of files
       -I, --include
              include names matching the given patterns
       -X, --exclude
              exclude names matching the given patterns
       -n, --dry-run
              do not perform actions, just print output
   rollback
       hg rollback
       This command should be used with care. There is only one level of
       rollback, and there is no way to undo a rollback. It will also
       restore the dirstate at the time of the last transaction, losing any
       dirstate changes since that time. This command does not alter the
       working directory.
       Transactions are used to encapsulate the effects of all commands that
       create new changesets or propagate existing changesets into a
       repository.
       For example, the following commands are transactional, and their
       effects can be rolled back:
       · commit
       · import
       · pull
       · push (with this repository as the destination)
       · unbundle
       To avoid permanent data loss, rollback will refuse to rollback a
       commit transaction if it isn't checked out. Use --force to override
       this protection.
       This command is not intended for use on public repositories. Once
       changes are visible for pull by other users, rolling a transaction
       back locally is ineffective (someone else may already have pulled the
       changes). Furthermore, a race is possible with readers of the
       repository; for example an in-progress pull from the repository may
       fail if a rollback is performed.
       Returns 0 on success, 1 if no rollback data is available.
       Options:
       -n, --dry-run
              do not perform actions, just print output
       -f, --force
              ignore safety measures
   root
       hg root
       Print the root directory of the current repository.
       Returns 0 on success.
   serve
       hg serve [OPTION]...
       Start a local HTTP repository browser and pull server. You can use
       this for ad-hoc sharing and browsing of repositories. It is
       recommended to use a real web server to serve a repository for longer
       periods of time.
       Please note that the server does not implement access control.  This
       means that, by default, anybody can read from the server and nobody
       can write to it by default. Set the web.allow_push option to * to
       allow everybody to push to the server. You should use a real web
       server if you need to authenticate users.
       By default, the server logs accesses to stdout and errors to stderr.
       Use the -A/--accesslog and -E/--errorlog options to log to files.
       To have the server choose a free port number to listen on, specify a
       port number of 0; in this case, the server will print the port number
       it uses.
       Returns 0 on success.
       Options:
       -A, --accesslog
              name of access log file to write to
       -d, --daemon
              run server in background
       --daemon-pipefds
              used internally by daemon mode
       -E, --errorlog
              name of error log file to write to
       -p, --port
              port to listen on (default: 8000)
       -a, --address
              address to listen on (default: all interfaces)
       --prefix
              prefix path to serve from (default: server root)
       -n, --name
              name to show in web pages (default: working directory)
       --web-conf
              name of the hgweb config file (see "hg help hgweb")
       --webdir-conf
              name of the hgweb config file (DEPRECATED)
       --pid-file
              name of file to write process ID to
       --stdio
              for remote clients
       --cmdserver
              for remote clients
       -t, --templates
              web templates to use
       --style
              template style to use
       -6, --ipv6
              use IPv6 in addition to IPv4
       --certificate
              SSL certificate file
   showconfig
       hg showconfig [-u] [NAME]...
       With no arguments, print names and values of all config items.
       With one argument of the form section.name, print just the value of
       that config item.
       With multiple arguments, print names and values of all config items
       with matching section names.
       With --debug, the source (filename and line number) is printed for
       each config item.
       Returns 0 on success.
       Options:
       -u, --untrusted
              show untrusted configuration options
              aliases: debugconfig
   status
       hg status [OPTION]... [FILE]...
       Show status of files in the repository. If names are given, only
       files that match are shown. Files that are clean or ignored or the
       source of a copy/move operation, are not listed unless -c/--clean,
       -i/--ignored, -C/--copies or -A/--all are given.  Unless options
       described with "show only ..." are given, the options -mardu are
       used.
       Option -q/--quiet hides untracked (unknown and ignored) files unless
       explicitly requested with -u/--unknown or -i/--ignored.
       Note   status may appear to disagree with diff if permissions have
              changed or a merge has occurred. The standard diff format does
              not report permission changes and diff only reports changes
              relative to one merge parent.
       If one revision is given, it is used as the base revision.  If two
       revisions are given, the differences between them are shown. The
       --change option can also be used as a shortcut to list the changed
       files of a revision from its first parent.
       The codes used to show the status of files are:
       M = modified
       A = added
       R = removed
       C = clean
       ! = missing (deleted by non-hg command, but still tracked)
       ? = not tracked
       I = ignored
         = origin of the previous file listed as A (added)
       Examples:
       · show changes in the working directory relative to a changeset:
         hg status --rev 9353
       · show all changes including copies in an existing changeset:
         hg status --copies --change 9353
       · get a NUL separated list of added files, suitable for xargs:
         hg status -an0
       Returns 0 on success.
       Options:
       -A, --all
              show status of all files
       -m, --modified
              show only modified files
       -a, --added
              show only added files
       -r, --removed
              show only removed files
       -d, --deleted
              show only deleted (but tracked) files
       -c, --clean
              show only files without changes
       -u, --unknown
              show only unknown (not tracked) files
       -i, --ignored
              show only ignored files
       -n, --no-status
              hide status prefix
       -C, --copies
              show source of copied files
       -0, --print0
              end filenames with NUL, for use with xargs
       --rev  show difference from revision
       --change
              list the changed files of a revision
       -I, --include

   summary
       hg summary [--remote]
       This generates a brief summary of the working directory state,
       including parents, branch, commit status, and available updates.
       With the --remote option, this will check the default paths for
       incoming and outgoing changes. This can be time-consuming.
       Returns 0 on success.
       Options:
       --remote

   tag
       hg tag [-f] [-l] [-m TEXT] [-d DATE] [-u USER] [-r REV] NAME...
       Name a particular revision using <name>.
       Tags are used to name particular revisions of the repository and are
       very useful to compare different revisions, to go back to significant
       earlier versions or to mark branch points as releases, etc. Changing
       an existing tag is normally disallowed; use -f/--force to override.
       If no revision is given, the parent of the working directory is used,
       or tip if no revision is checked out.
       To facilitate version control, distribution, and merging of tags,
       they are stored as a file named ".hgtags" which is managed similarly
       to other project files and can be hand-edited if necessary. This also
       means that tagging creates a new commit. The file ".hg/localtags" is
       used for local tags (not shared among repositories).
       Tag commits are usually made at the head of a branch. If the parent
       of the working directory is not a branch head, hg tag aborts; use
       -f/--force to force the tag commit to be based on a non-head
       changeset.
       See hg help dates for a list of formats valid for -d/--date.
       Since tag names have priority over branch names during revision
       lookup, using an existing branch name as a tag name is discouraged.
       Returns 0 on success.
       Options:
       -f, --force
              force tag
       -l, --local
              make the tag local
       -r, --rev
              revision to tag
       --remove
              remove a tag
       -e, --edit
              edit commit message
       -m, --message
              use <text> as commit message
       -d, --date
              record the specified date as commit date
       -u, --user
              record the specified user as committer
   tags
       hg tags
       This lists both regular and local tags. When the -v/--verbose switch
       is used, a third column "local" is printed for local tags.
       Returns 0 on success.
   tip
       hg tip [-p] [-g]
       The tip revision (usually just called the tip) is the changeset most
       recently added to the repository (and therefore the most recently
       changed head).
       If you have just made a commit, that commit will be the tip. If you
       have just pulled changes from another repository, the tip of that
       repository becomes the current tip. The "tip" tag is special and
       cannot be renamed or assigned to a different changeset.
       Returns 0 on success.
       Options:
       -p, --patch
              show patch
       -g, --git
              use git extended diff format

   unbundle
       hg unbundle [-u] FILE...
       Apply one or more compressed changegroup files generated by the
       bundle command.
       Returns 0 on success, 1 if an update has unresolved files.
       Options:
       -u, --update
              update to new branch head if changesets were unbundled
   update
       hg update [-c] [-C] [-d DATE] [[-r] REV]
       Update the repository's working directory to the specified changeset.
       If no changeset is specified, update to the tip of the current named
       branch and move the current bookmark (see hg help bookmarks).
       Update sets the working directory's parent revision to the specified
       changeset (see hg help parents).
       If the changeset is not a descendant or ancestor of the working
       directory's parent, the update is aborted. With the -c/--check
       option, the working directory is checked for uncommitted changes; if
       none are found, the working directory is updated to the specified
       changeset.
       The following rules apply when the working directory contains
       uncommitted changes:
       1. If neither -c/--check nor -C/--clean is specified, and if the
          requested changeset is an ancestor or descendant of the working
          directory's parent, the uncommitted changes are merged into the
          requested changeset and the merged result is left uncommitted. If
          the requested changeset is not an ancestor or descendant (that is,
          it is on another branch), the update is aborted and the
          uncommitted changes are preserved.
       2. With the -c/--check option, the update is aborted and the
          uncommitted changes are preserved.
       3. With the -C/--clean option, uncommitted changes are discarded and
          the working directory is updated to the requested changeset.
       To cancel an uncommitted merge (and lose your changes), use hg update
       --clean ..
       Use null as the changeset to remove the working directory (like hg
       clone -U).
       If you want to revert just one file to an older revision, use hg
       revert [-r REV] NAME.
       See hg help dates for a list of formats valid for -d/--date.
       Returns 0 on success, 1 if there are unresolved files.
       Options:
       -C, --clean
              discard uncommitted changes (no backup)
       -c, --check

   verify
       hg verify
       Verify the integrity of the current repository.
       This will perform an extensive check of the repository's integrity,
       validating the hashes and checksums of each entry in the changelog,
       manifest, and tracked files, as well as the integrity of their

DATE FORMATS         top

       Some commands allow the user to specify a date, e.g.:
       · backout, commit, import, tag: Specify the commit date.
       · log, revert, update: Select revision(s) by date.
       Many date formats are valid. Here are some examples:
       · Wed Dec 6 13:18:29 2006 (local timezone assumed)
       · Dec 6 13:18 -0600 (year assumed, time offset provided)
       · Dec 6 13:18 UTC (UTC and GMT are aliases for +0000)
       · Dec 6 (midnight)
       · 13:18 (today assumed)
       · 3:39 (3:39AM assumed)
       · 3:39pm (15:39)
       · 2006-12-06 13:18:29 (ISO 8601 format)
       · 2006-12-6 13:18
       · 2006-12-6
       · 12-6
       · 12/6
       · 12/6/6 (Dec 6 2006)
       · today (midnight)
       · yesterday (midnight)
       · now - right now
       Lastly, there is Mercurial's internal format:
       · 1165432709 0 (Wed Dec 6 13:18:29 2006 UTC)
       This is the internal representation format for dates. The first
       number is the number of seconds since the epoch (1970-01-01 00:00
       UTC). The second is the offset of the local timezone, in seconds west
       of UTC (negative if the timezone is east of UTC).
       The log command also accepts date ranges:
       · <DATE - at or before a given date/time
       · >DATE - on or after a given date/time
       · DATE to DATE - a date range, inclusive
       · -DAYS - within a given number of days of today

DIFF FORMATS         top

       Mercurial's default format for showing changes between two versions
       of a file is compatible with the unified format of GNU diff, which
       can be used by GNU patch and many other standard tools.
       While this standard format is often enough, it does not encode the
       following information:
       · executable status and other permission bits
       · copy or rename information
       · changes in binary files
       · creation or deletion of empty files
       Mercurial also supports the extended diff format from the git VCS
       which addresses these limitations. The git diff format is not
       produced by default because a few widespread tools still do not
       understand this format.
       This means that when generating diffs from a Mercurial repository
       (e.g. with hg export), you should be careful about things like file
       copies and renames or other things mentioned above, because when
       applying a standard diff to a different repository, this extra
       information is lost. Mercurial's internal operations (like push and
       pull) are not affected by this, because they use an internal binary
       format for communicating changes.
       To make Mercurial produce the git extended diff format, use the --git
       option available for many commands, or set 'git = True' in the [diff]
       section of your configuration file. You do not need to set this
       option when importing diffs in this format or using them in the mq
       extension.

ENVIRONMENT VARIABLES         top

       HG     Path to the 'hg' executable, automatically passed when running
              hooks, extensions or external tools. If unset or empty, this
              is the hg executable's name if it's frozen, or an executable
              named 'hg' (with %PATHEXT% [defaulting to COM/EXE/BAT/CMD]
              extensions on Windows) is searched.
       HGEDITOR
              This is the name of the editor to run when committing. See
              EDITOR.
              (deprecated, use configuration file)
       HGENCODING
              This overrides the default locale setting detected by
              Mercurial.  This setting is used to convert data including
              usernames, changeset descriptions, tag names, and branches.
              This setting can be overridden with the --encoding
              command-line option.
       HGENCODINGMODE
              This sets Mercurial's behavior for handling unknown characters
              while transcoding user input. The default is "strict", which
              causes Mercurial to abort if it can't map a character. Other
              settings include "replace", which replaces unknown characters,
              and "ignore", which drops them. This setting can be overridden
              with the --encodingmode command-line option.
       HGENCODINGAMBIGUOUS
              This sets Mercurial's behavior for handling characters with
              "ambiguous" widths like accented Latin characters with East
              Asian fonts. By default, Mercurial assumes ambiguous
              characters are narrow, set this variable to "wide" if such
              characters cause formatting problems.
       HGMERGE
              An executable to use for resolving merge conflicts. The
              program will be executed with three arguments: local file,
              remote file, ancestor file.
              (deprecated, use configuration file)
       HGRCPATH
              A list of files or directories to search for configuration
              files. Item separator is ":" on Unix, ";" on Windows. If
              HGRCPATH is not set, platform default search path is used. If
              empty, only the .hg/hgrc from the current repository is read.
              For each element in HGRCPATH:
              · if it's a directory, all files ending with .rc are added
              · otherwise, the file itself will be added
       HGPLAIN
              When set, this disables any configuration settings that might
              change Mercurial's default output. This includes encoding,
              defaults, verbose mode, debug mode, quiet mode, tracebacks,
              and localization. This can be useful when scripting against
              Mercurial in the face of existing user configuration.
              Equivalent options set via command line flags or environment
              variables are not overridden.
       HGPLAINEXCEPT
              This is a comma-separated list of features to preserve when
              HGPLAIN is enabled. Currently the only value supported is
              "i18n", which preserves internationalization in plain mode.
              Setting HGPLAINEXCEPT to anything (even an empty string) will
              enable plain mode.
       HGUSER This is the string used as the author of a commit. If not set,
              available values will be considered in this order:
              · HGUSER (deprecated)
              · configuration files from the HGRCPATH
              · EMAIL
              · interactive prompt
              · LOGNAME (with @hostname appended)
              (deprecated, use configuration file)
       EMAIL  May be used as the author of a commit; see HGUSER.
       LOGNAME
              May be used as the author of a commit; see HGUSER.
       VISUAL This is the name of the editor to use when committing. See
              EDITOR.
       EDITOR Sometimes Mercurial needs to open a text file in an editor for
              a user to modify, for example when writing commit messages.
              The editor it uses is determined by looking at the environment
              variables HGEDITOR, VISUAL and EDITOR, in that order. The
              first non-empty one is chosen. If all of them are empty, the
              editor defaults to 'vi'.
       PYTHONPATH
              This is used by Python to find imported modules and may need
              to be set appropriately if this Mercurial is not installed
              system-wide.

USING ADDITIONAL FEATURES         top

       Mercurial has the ability to add new features through the use of
       extensions. Extensions may add new commands, add options to existing
       commands, change the default behavior of commands, or implement
       hooks.
       Extensions are not loaded by default for a variety of reasons: they
       can increase startup overhead; they may be meant for advanced usage
       only; they may provide potentially dangerous abilities (such as
       letting you destroy or modify history); they might not be ready for
       prime time; or they may alter some usual behaviors of stock
       Mercurial. It is thus up to the user to activate extensions as
       needed.
       To enable the "foo" extension, either shipped with Mercurial or in
       the Python search path, create an entry for it in your configuration
       file, like this:
       [extensions]
       foo =
       You may also specify the full path to an extension:
       [extensions]
       myfeature = ~/.hgext/myfeature.py
       To explicitly disable an extension enabled in a configuration file of
       broader scope, prepend its path with !:
       [extensions]
       # disabling extension bar residing in /path/to/extension/bar.py
       bar = !/path/to/extension/bar.py
       # ditto, but no path was supplied for extension baz
       baz = !
       disabled extensions:

SPECIFYING FILE SETS         top

       Mercurial supports a functional language for selecting a set of
       files.
       Like other file patterns, this pattern type is indicated by a prefix,
       'set:'. The language supports a number of predicates which are joined
       by infix operators. Parenthesis can be used for grouping.
       Identifiers such as filenames or patterns must be quoted with single
       or double quotes if they contain characters outside of
       [.*{}[]?/\_a-zA-Z0-9\x80-\xff] or if they match one of the predefined
       predicates. This generally applies to file patterns other than globs
       and arguments for predicates.
       Special characters can be used in quoted identifiers by escaping
       them, e.g., \n is interpreted as a newline. To prevent them from
       being interpreted, strings can be prefixed with r, e.g. r'...'.
       There is a single prefix operator:
       not x
              Files not in x. Short form is ! x.
       These are the supported infix operators:
       x and y
              The intersection of files in x and y. Short form is x & y.
       x or y
              The union of files in x and y. There are two alternative short
              forms: x | y and x + y.
       x - y
              Files in x but not in y.
       The following predicates are supported:
       added()
              File that is added according to status.
       binary()
              File that appears to be binary (contains NUL bytes).
       clean()
              File that is clean according to status.
       copied()
              File that is recorded as being copied.
       deleted()
              File that is deleted according to status.
       encoding(name)
              File can be successfully decoded with the given character
              encoding. May not be useful for encodings other than ASCII and
              UTF-8.
       eol(style)
              File contains newlines of the given style (dos, unix, mac).
              Binary files are excluded, files with mixed line endings match
              multiple styles.
       exec()
              File that is marked as executable.
       grep(regex)
              File contains the given regular expression.
       hgignore()
              File that matches the active .hgignore pattern.
       ignored()
              File that is ignored according to status. These files will
              only be considered if this predicate is used.
       modified()
              File that is modified according to status.
       removed()
              File that is removed according to status.
       resolved()
              File that is marked resolved according to the resolve state.
       size(expression)
              File size matches the given expression. Examples:
              · 1k (files from 1024 to 2047 bytes)
              · < 20k (files less than 20480 bytes)
              · >= .5MB (files at least 524288 bytes)
              · 4k - 1MB (files from 4096 bytes to 1048576 bytes)
       subrepo([pattern])
              Subrepositories whose paths match the given pattern.
       symlink()
              File that is marked as a symlink.
       unknown()
              File that is unknown according to status. These files will
              only be considered if this predicate is used.
       unresolved()
              File that is marked unresolved according to the resolve state.
       Some sample queries:
       · Show status of files that appear to be binary in the working
         directory:
         hg status -A "set:binary()"
       · Forget files that are in .hgignore but are already tracked:
         hg forget "set:hgignore() and not ignored()"
       · Find text files that contain a string:
         hg locate "set:grep(magic) and not binary()"
       · Find C files in a non-standard encoding:
         hg locate "set:**.c and not encoding('UTF-8')"
       · Revert copies of large binary files:
         hg revert "set:copied() and binary() and size('>1M')"
       · Remove files listed in foo.lst that contain the letter a or b:
         hg remove "set: 'listfile:foo.lst' and (**a* or **b*)"
       See also hg help patterns.

GLOSSARY         top

       Ancestor
              Any changeset that can be reached by an unbroken chain of
              parent changesets from a given changeset. More precisely, the
              ancestors of a changeset can be defined by two properties: a
              parent of a changeset is an ancestor, and a parent of an
              ancestor is an ancestor. See also: 'Descendant'.
       Bookmark
              Bookmarks are pointers to certain commits that move when
              committing. They are similar to tags in that it is possible to
              use bookmark names in all places where Mercurial expects a
              changeset ID, e.g., with hg update. Unlike tags, bookmarks
              move along when you make a commit.
              Bookmarks can be renamed, copied and deleted. Bookmarks are
              local, unless they are explicitly pushed or pulled between
              repositories.  Pushing and pulling bookmarks allow you to
              collaborate with others on a branch without creating a named
              branch.
       Branch (Noun) A child changeset that has been created from a parent
              that is not a head. These are known as topological branches,
              see 'Branch, topological'. If a topological branch is named,
              it becomes a named branch. If a topological branch is not
              named, it becomes an anonymous branch. See 'Branch, anonymous'
              and 'Branch, named'.
              Branches may be created when changes are pulled from or pushed
              to a remote repository, since new heads may be created by
              these operations. Note that the term branch can also be used
              informally to describe a development process in which certain
              development is done independently of other development. This
              is sometimes done explicitly with a named branch, but it can
              also be done locally, using bookmarks or clones and anonymous
              branches.
              Example: "The experimental branch".
              (Verb) The action of creating a child changeset which results
              in its parent having more than one child.
              Example: "I'm going to branch at X".
       Branch, anonymous
              Every time a new child changeset is created from a parent that
              is not a head and the name of the branch is not changed, a new
              anonymous branch is created.
       Branch, closed
              A named branch whose branch heads have all been closed.
       Branch, default
              The branch assigned to a changeset when no name has previously
              been assigned.
       Branch head
              See 'Head, branch'.
       Branch, inactive
              If a named branch has no topological heads, it is considered
              to be inactive. As an example, a feature branch becomes
              inactive when it is merged into the default branch. The hg
              branches command shows inactive branches by default, though
              they can be hidden with hg branches --active.
              NOTE: this concept is deprecated because it is too implicit.
              Branches should now be explicitly closed using hg commit
              --close-branch when they are no longer needed.
       Branch, named
              A collection of changesets which have the same branch name. By
              default, children of a changeset in a named branch belong to
              the same named branch. A child can be explicitly assigned to a
              different branch. See hg help branch, hg help branches and hg
              commit --close-branch for more information on managing
              branches.
              Named branches can be thought of as a kind of namespace,
              dividing the collection of changesets that comprise the
              repository into a collection of disjoint subsets. A named
              branch is not necessarily a topological branch. If a new named
              branch is created from the head of another named branch, or
              the default branch, but no further changesets are added to
              that previous branch, then that previous branch will be a
              branch in name only.
       Branch tip
              See 'Tip, branch'.
       Branch, topological
              Every time a new child changeset is created from a parent that
              is not a head, a new topological branch is created. If a
              topological branch is named, it becomes a named branch. If a
              topological branch is not named, it becomes an anonymous
              branch of the current, possibly default, branch.
       Changelog
              A record of the changesets in the order in which they were
              added to the repository. This includes details such as
              changeset id, author, commit message, date, and list of
              changed files.
       Changeset
              A snapshot of the state of the repository used to record a
              change.
       Changeset, child
              The converse of parent changeset: if P is a parent of C, then
              C is a child of P. There is no limit to the number of children
              that a changeset may have.
       Changeset id
              A SHA-1 hash that uniquely identifies a changeset. It may be
              represented as either a "long" 40 hexadecimal digit string, or
              a "short" 12 hexadecimal digit string.
       Changeset, merge
              A changeset with two parents. This occurs when a merge is
              committed.
       Changeset, parent
              A revision upon which a child changeset is based.
              Specifically, a parent changeset of a changeset C is a
              changeset whose node immediately precedes C in the DAG.
              Changesets have at most two parents.
       Checkout
              (Noun) The working directory being updated to a specific
              revision. This use should probably be avoided where possible,
              as changeset is much more appropriate than checkout in this
              context.
              Example: "I'm using checkout X."
              (Verb) Updating the working directory to a specific changeset.
              See hg help update.
              Example: "I'm going to check out changeset X."
       Child changeset
              See 'Changeset, child'.
       Close changeset
              See 'Head, closed branch'
       Closed branch
              See 'Branch, closed'.
       Clone  (Noun) An entire or partial copy of a repository. The partial
              clone must be in the form of a revision and its ancestors.
              Example: "Is your clone up to date?".
              (Verb) The process of creating a clone, using hg clone.
              Example: "I'm going to clone the repository".
       Closed branch head
              See 'Head, closed branch'.
       Commit (Noun) A synonym for changeset.
              Example: "Is the bug fixed in your recent commit?"
              (Verb) The act of recording changes to a repository. When
              files are committed in a working directory, Mercurial finds
              the differences between the committed files and their parent
              changeset, creating a new changeset in the repository.
              Example: "You should commit those changes now."
       Cset   A common abbreviation of the term changeset.
       DAG    The repository of changesets of a distributed version control
              system (DVCS) can be described as a directed acyclic graph
              (DAG), consisting of nodes and edges, where nodes correspond
              to changesets and edges imply a parent -> child relation. This
              graph can be visualized by graphical tools such as hg glog
              (graphlog). In Mercurial, the DAG is limited by the
              requirement for children to have at most two parents.
       Default branch
              See 'Branch, default'.
       Descendant
              Any changeset that can be reached by a chain of child
              changesets from a given changeset. More precisely, the
              descendants of a changeset can be defined by two properties:
              the child of a changeset is a descendant, and the child of a
              descendant is a descendant. See also: 'Ancestor'.
       Diff   (Noun) The difference between the contents and attributes of
              files in two changesets or a changeset and the current working
              directory. The difference is usually represented in a standard
              form called a "diff" or "patch". The "git diff" format is used
              when the changes include copies, renames, or changes to file
              attributes, none of which can be represented/handled by
              classic "diff" and "patch".
              Example: "Did you see my correction in the diff?"
              (Verb) Diffing two changesets is the action of creating a diff
              or patch.
              Example: "If you diff with changeset X, you will see what I
              mean."
       Directory, working
              The working directory represents the state of the files
              tracked by Mercurial, that will be recorded in the next
              commit. The working directory initially corresponds to the
              snapshot at an existing changeset, known as the parent of the
              working directory. See 'Parent, working directory'. The state
              may be modified by changes to the files introduced manually or
              by a merge. The repository metadata exists in the .hg
              directory inside the working directory.
       Draft  Changesets in the draft phase have not been shared with
              publishing repositories and may thus be safely changed by
              history-modifying extensions. See hg help phases.
       Graph  See DAG and hg help graphlog.
       Head   The term 'head' may be used to refer to both a branch head or
              a repository head, depending on the context. See 'Head,
              branch' and 'Head, repository' for specific definitions.
              Heads are where development generally takes place and are the
              usual targets for update and merge operations.
       Head, branch
              A changeset with no descendants on the same named branch.
       Head, closed branch
              A changeset that marks a head as no longer interesting. The
              closed head is no longer listed by hg heads. A branch is
              considered closed when all its heads are closed and
              consequently is not listed by hg branches.
              Closed heads can be re-opened by committing new changeset as
              the child of the changeset that marks a head as closed.
       Head, repository
              A topological head which has not been closed.
       Head, topological
              A changeset with no children in the repository.
       History, immutable
              Once committed, changesets cannot be altered.  Extensions
              which appear to change history actually create new changesets
              that replace existing ones, and then destroy the old
              changesets. Doing so in public repositories can result in old
              changesets being reintroduced to the repository.
       History, rewriting
              The changesets in a repository are immutable. However,
              extensions to Mercurial can be used to alter the repository,
              usually in such a way as to preserve changeset contents.
       Immutable history
              See 'History, immutable'.
       Merge changeset
              See 'Changeset, merge'.
       Manifest
              Each changeset has a manifest, which is the list of files that
              are tracked by the changeset.
       Merge  Used to bring together divergent branches of work. When you
              update to a changeset and then merge another changeset, you
              bring the history of the latter changeset into your working
              directory. Once conflicts are resolved (and marked), this
              merge may be committed as a merge changeset, bringing two
              branches together in the DAG.
       Named branch
              See 'Branch, named'.
       Null changeset
              The empty changeset. It is the parent state of
              newly-initialized repositories and repositories with no
              checked out revision. It is thus the parent of root changesets
              and the effective ancestor when merging unrelated changesets.
              Can be specified by the alias 'null' or by the changeset ID
              '000000000000'.
       Parent See 'Changeset, parent'.
       Parent changeset
              See 'Changeset, parent'.
       Parent, working directory
              The working directory parent reflects a virtual revision which
              is the child of the changeset (or two changesets with an
              uncommitted merge) shown by hg parents. This is changed with
              hg update. Other commands to see the working directory parent
              are hg summary and hg id. Can be specified by the alias ".".
       Patch  (Noun) The product of a diff operation.
              Example: "I've sent you my patch."
              (Verb) The process of using a patch file to transform one
              changeset into another.
              Example: "You will need to patch that revision."
       Phase  A per-changeset state tracking how the changeset has been or
              should be shared. See hg help phases.
       Public Changesets in the public phase have been shared with
              publishing repositories and are therefore considered
              immutable. See hg help phases.
       Pull   An operation in which changesets in a remote repository which
              are not in the local repository are brought into the local
              repository. Note that this operation without special arguments
              only updates the repository, it does not update the files in
              the working directory. See hg help pull.
       Push   An operation in which changesets in a local repository which
              are not in a remote repository are sent to the remote
              repository. Note that this operation only adds changesets
              which have been committed locally to the remote repository.
              Uncommitted changes are not sent. See hg help push.
       Repository
              The metadata describing all recorded states of a collection of
              files. Each recorded state is represented by a changeset. A
              repository is usually (but not always) found in the .hg
              subdirectory of a working directory. Any recorded state can be
              recreated by "updating" a working directory to a specific
              changeset.
       Repository head
              See 'Head, repository'.
       Revision
              A state of the repository at some point in time. Earlier
              revisions can be updated to by using hg update.  See also
              'Revision number'; See also 'Changeset'.
       Revision number
              This integer uniquely identifies a changeset in a specific
              repository. It represents the order in which changesets were
              added to a repository, starting with revision number 0. Note
              that the revision number may be different in each clone of a
              repository. To identify changesets uniquely between different
              clones, see 'Changeset id'.
       Revlog History storage mechanism used by Mercurial. It is a form of
              delta encoding, with occasional full revision of data followed
              by delta of each successive revision. It includes data and an
              index pointing to the data.
       Rewriting history
              See 'History, rewriting'.
       Root   A changeset that has only the null changeset as its parent.
              Most repositories have only a single root changeset.
       Secret Changesets in the secret phase may not be shared via push,
              pull, or clone. See hg help phases.
       Tag    An alternative name given to a changeset. Tags can be used in
              all places where Mercurial expects a changeset ID, e.g., with
              hg update. The creation of a tag is stored in the history and
              will thus automatically be shared with other using push and
              pull.
       Tip    The changeset with the highest revision number. It is the
              changeset most recently added in a repository.
       Tip, branch
              The head of a given branch with the highest revision number.
              When a branch name is used as a revision identifier, it refers
              to the branch tip. See also 'Branch, head'. Note that because
              revision numbers may be different in different repository
              clones, the branch tip may be different in different cloned
              repositories.
       Update (Noun) Another synonym of changeset.
              Example: "I've pushed an update".
              (Verb) This term is usually used to describe updating the
              state of the working directory to that of a specific
              changeset. See hg help update.
              Example: "You should update".
       Working directory
              See 'Directory, working'.
       Working directory parent
              See 'Parent, working directory'.

SYNTAX FOR MERCURIAL IGNORE FILES         top

   Synopsis
       The Mercurial system uses a file called .hgignore in the root
       directory of a repository to control its behavior when it searches
       for files that it is not currently tracking.
   Description
       The working directory of a Mercurial repository will often contain
       files that should not be tracked by Mercurial. These include backup
       files created by editors and build products created by compilers.
       These files can be ignored by listing them in a .hgignore file in the
       root of the working directory. The .hgignore file must be created
       manually. It is typically put under version control, so that the
       settings will propagate to other repositories with push and pull.
       An untracked file is ignored if its path relative to the repository
       root directory, or any prefix path of that path, is matched against
       any pattern in .hgignore.
       For example, say we have an untracked file, file.c, at a/b/file.c
       inside our repository. Mercurial will ignore file.c if any pattern in
       .hgignore matches a/b/file.c, a/b or a.
       In addition, a Mercurial configuration file can reference a set of
       per-user or global ignore files. See the ignore configuration key on
       the [ui] section of hg help config for details of how to configure
       these files.
       To control Mercurial's handling of files that it manages, many
       commands support the -I and -X options; see hg help <command> and hg
       help patterns for details.
       Files that are already tracked are not affected by .hgignore, even if
       they appear in .hgignore. An untracked file X can be explicitly added
       with hg add X, even if X would be excluded by a pattern in .hgignore.
   Syntax
       An ignore file is a plain text file consisting of a list of patterns,
       with one pattern per line. Empty lines are skipped. The # character
       is treated as a comment character, and the \ character is treated as
       an escape character.
       Mercurial supports several pattern syntaxes. The default syntax used
       is Python/Perl-style regular expressions.
       To change the syntax used, use a line of the following form:
       syntax: NAME
       where NAME is one of the following:
       regexp
              Regular expression, Python/Perl syntax.
       glob
              Shell-style glob.
       The chosen syntax stays in effect when parsing all patterns that
       follow, until another syntax is selected.
       Neither glob nor regexp patterns are rooted. A glob-syntax pattern of
       the form *.c will match a file ending in .c in any directory, and a
       regexp pattern of the form \.c$ will do the same. To root a regexp
       pattern, start it with ^.
       Note   Patterns specified in other than .hgignore are always rooted.
              Please see hg help patterns for details.
   Example
       Here is an example ignore file.
       # use glob syntax.
       syntax: glob
       *.elc
       *.pyc
       *~
       # switch to regexp syntax.
       syntax: regexp
       ^\.pc/

CONFIGURING HGWEB         top

       Mercurial's internal web server, hgweb, can serve either a single
       repository, or a tree of repositories. In the second case, repository
       paths and global options can be defined using a dedicated
       configuration file common to hg serve, hgweb.wsgi, hgweb.cgi and
       hgweb.fcgi.
       This file uses the same syntax as other Mercurial configuration files
       but recognizes only the following sections:
          · web
          · paths
          · collections
       The web options are thoroughly described in hg help config.
       The paths section maps URL paths to paths of repositories in the
       filesystem. hgweb will not expose the filesystem directly - only
       Mercurial repositories can be published and only according to the
       configuration.
       The left hand side is the path in the URL. Note that hgweb reserves
       subpaths like rev or file, try using different names for nested
       repositories to avoid confusing effects.
       The right hand side is the path in the filesystem. If the specified
       path ends with * or ** the filesystem will be searched recursively
       for repositories below that point.  With * it will not recurse into
       the repositories it finds (except for .hg/patches).  With ** it will
       also search inside repository working directories and possibly find
       subrepositories.
       In this example:
       [paths]
       /projects/a = /srv/tmprepos/a
       /projects/b = c:/repos/b
       / = /srv/repos/*
       /user/bob = /home/bob/repos/**
       · The first two entries make two repositories in different
         directories appear under the same directory in the web interface
       · The third entry will publish every Mercurial repository found in
         /srv/repos/, for instance the repository /srv/repos/quux/ will
         appear as http://server/quux/ 
       · The fourth entry will publish both http://server/user/bob/quux/ and
         http://server/user/bob/quux/testsubrepo/ 
       The collections section is deprecated and has been superseded by
       paths.

MERGE TOOLS         top

       To merge files Mercurial uses merge tools.
       A merge tool combines two different versions of a file into a merged
       file. Merge tools are given the two files and the greatest common
       ancestor of the two file versions, so they can determine the changes
       made on both branches.
       Merge tools are used both for hg resolve, hg merge, hg update, hg
       backout and in several extensions.
       Usually, the merge tool tries to automatically reconcile the files by
       combining all non-overlapping changes that occurred separately in the
       two different evolutions of the same initial base file. Furthermore,
       some interactive merge programs make it easier to manually resolve
       conflicting merges, either in a graphical way, or by inserting some
       conflict markers. Mercurial does not include any interactive merge
       programs but relies on external tools for that.
   Available merge tools
       External merge tools and their properties are configured in the
       merge-tools configuration section - see hgrc(5) - but they can often
       just be named by their executable.
       A merge tool is generally usable if its executable can be found on
       the system and if it can handle the merge. The executable is found if
       it is an absolute or relative executable path or the name of an
       application in the executable search path. The tool is assumed to be
       able to handle the merge if it can handle symlinks if the file is a
       symlink, if it can handle binary files if the file is binary, and if
       a GUI is available if the tool requires a GUI.
       There are some internal merge tools which can be used. The internal
       merge tools are:
       internal:dump
              Creates three versions of the files to merge, containing the
              contents of local, other and base. These files can then be
              used to perform a merge manually. If the file to be merged is
              named a.txt, these files will accordingly be named
              a.txt.local, a.txt.other and a.txt.base and they will be
              placed in the same directory as a.txt.
       internal:fail
              Rather than attempting to merge files that were modified on
              both branches, it marks them as unresolved. The resolve
              command must be used to resolve these conflicts.
       internal:local
              Uses the local version of files as the merged version.
       internal:merge
              Uses the internal non-interactive simple merge algorithm for
              merging files. It will fail if there are any conflicts and
              leave markers in the partially merged file.
       internal:other
              Uses the other version of files as the merged version.
       internal:prompt
              Asks the user which of the local or the other version to keep
              as the merged version.
       Internal tools are always available and do not require a GUI but will
       by default not handle symlinks or binary files.
   Choosing a merge tool
       Mercurial uses these rules when deciding which merge tool to use:
       1. If a tool has been specified with the --tool option to merge or
          resolve, it is used.  If it is the name of a tool in the
          merge-tools configuration, its configuration is used. Otherwise
          the specified tool must be executable by the shell.
       2. If the HGMERGE environment variable is present, its value is used
          and must be executable by the shell.
       3. If the filename of the file to be merged matches any of the
          patterns in the merge-patterns configuration section, the first
          usable merge tool corresponding to a matching pattern is used.
          Here, binary capabilities of the merge tool are not considered.
       4. If ui.merge is set it will be considered next. If the value is not
          the name of a configured tool, the specified value is used and
          must be executable by the shell. Otherwise the named tool is used
          if it is usable.
       5. If any usable merge tools are present in the merge-tools
          configuration section, the one with the highest priority is used.
       6. If a program named hgmerge can be found on the system, it is used
          - but it will by default not be used for symlinks and binary
          files.
       7. If the file to be merged is not binary and is not a symlink, then
          internal:merge is used.
       8. The merge of the file fails and must be resolved before commit.
       Note   After selecting a merge program, Mercurial will by default
              attempt to merge the files using a simple merge algorithm
              first. Only if it doesn't succeed because of conflicting
              changes Mercurial will actually execute the merge program.
              Whether to use the simple merge algorithm first can be
              controlled by the premerge setting of the merge tool. Premerge
              is enabled by default unless the file is binary or a symlink.
       See the merge-tools and ui sections of hgrc(5) for details on the
       configuration of merge tools.

SPECIFYING MULTIPLE REVISIONS         top

       When Mercurial accepts more than one revision, they may be specified
       individually, or provided as a topologically continuous range,
       separated by the ":" character.
       The syntax of range notation is [BEGIN]:[END], where BEGIN and END
       are revision identifiers. Both BEGIN and END are optional. If BEGIN
       is not specified, it defaults to revision number 0. If END is not
       specified, it defaults to the tip. The range ":" thus means "all
       revisions".
       If BEGIN is greater than END, revisions are treated in reverse order.
       A range acts as a closed interval. This means that a range of 3:5
       gives 3, 4 and 5. Similarly, a range of 9:6 gives 9, 8, 7, and 6.

FILE NAME PATTERNS         top

       Mercurial accepts several notations for identifying one or more files
       at a time.
       By default, Mercurial treats filenames as shell-style extended glob
       patterns.
       Alternate pattern notations must be specified explicitly.
       Note   Patterns specified in .hgignore are not rooted.  Please see hg
              help hgignore for details.
       To use a plain path name without any pattern matching, start it with
       path:. These path names must completely match starting at the current
       repository root.
       To use an extended glob, start a name with glob:. Globs are rooted at
       the current directory; a glob such as *.c will only match files in
       the current directory ending with .c.
       The supported glob syntax extensions are ** to match any string
       across path separators and {a,b} to mean "a or b".
       To use a Perl/Python regular expression, start a name with re:.
       Regexp pattern matching is anchored at the root of the repository.
       To read name patterns from a file, use listfile: or listfile0:.  The
       latter expects null delimited patterns while the former expects line
       feeds. Each string read from the file is itself treated as a file
       pattern.
       Plain examples:
       path:foo/bar   a name bar in a directory named foo in the root
                      of the repository
       path:path:name a file or directory named "path:name"
       Glob examples:
       glob:*.c       any name ending in ".c" in the current directory
       *.c            any name ending in ".c" in the current directory
       **.c           any name ending in ".c" in any subdirectory of the
                      current directory including itself.
       foo/*.c        any name ending in ".c" in the directory foo
       foo/**.c       any name ending in ".c" in any subdirectory of foo
                      including itself.
       Regexp examples:
       re:.*\.c$      any name ending in ".c", anywhere in the repository
       File examples:
       listfile:list.txt  read list from list.txt with one file pattern per line
       listfile0:list.txt read list from list.txt with null byte delimiters
       See also hg help filesets.

WORKING WITH PHASES         top

   What are phases?
       Phases are a system for tracking which changesets have been or should
       be shared. This helps prevent common mistakes when modifying history
       (for instance, with the mq or rebase extensions).
       Each changeset in a repository is in one of the following phases:
          · public : changeset is visible on a public server
          · draft : changeset is not yet published
          · secret : changeset should not be pushed, pulled, or cloned
       These phases are ordered (public < draft < secret) and no changeset
       can be in a lower phase than its ancestors. For instance, if a
       changeset is public, all its ancestors are also public. Lastly,
       changeset phases should only be changed towards the public phase.
   How are phases managed?
       For the most part, phases should work transparently. By default, a
       changeset is created in the draft phase and is moved into the public
       phase when it is pushed to another repository.
       Once changesets become public, extensions like mq and rebase will
       refuse to operate on them to prevent creating duplicate changesets.
       Phases can also be manually manipulated with the hg phase command if
       needed. See hg help -v phase for examples.
   Phases and servers
       Normally, all servers are publishing by default. This means:
       - all draft changesets that are pulled or cloned appear in phase
       public on the client
       - all draft changesets that are pushed appear as public on both
       client and server
       - secret changesets are neither pushed, pulled, or cloned
       Note   Pulling a draft changeset from a publishing server does not
              mark it as public on the server side due to the read-only
              nature of pull.
       Sometimes it may be desirable to push and pull changesets in the
       draft phase to share unfinished work. This can be done by setting a
       repository to disable publishing in its configuration file:
       [phases]
       publish = False
       See hg help config for more information on config files.
       Note   Servers running older versions of Mercurial are treated as
              publishing.
   Examples
          · list changesets in draft or secret phase:
            hg log -r "not public()"
          · change all secret changesets to draft:
            hg phase --draft "secret()"
          · forcibly move the current changeset and descendants from public
            to draft:
            hg phase --force --draft .
          · show a list of changeset revision and phase:
            hg log --template "{rev} {phase}\n"
          · resynchronize draft changesets relative to a remote repository:
            hg phase -fd 'outgoing(URL)'
       See hg help phase for more information on manually manipulating
       phases.

SPECIFYING SINGLE REVISIONS         top

       Mercurial supports several ways to specify individual revisions.
       A plain integer is treated as a revision number. Negative integers
       are treated as sequential offsets from the tip, with -1 denoting the
       tip, -2 denoting the revision prior to the tip, and so forth.
       A 40-digit hexadecimal string is treated as a unique revision
       identifier.
       A hexadecimal string less than 40 characters long is treated as a
       unique revision identifier and is referred to as a short-form
       identifier. A short-form identifier is only valid if it is the prefix
       of exactly one full-length identifier.
       Any other string is treated as a bookmark, tag, or branch name. A
       bookmark is a movable pointer to a revision. A tag is a permanent
       name associated with a revision. A branch name denotes the tipmost
       revision of that branch. Bookmark, tag, and branch names must not
       contain the ":" character.
       The reserved name "tip" always identifies the most recent revision.
       The reserved name "null" indicates the null revision. This is the
       revision of an empty repository, and the parent of revision 0.
       The reserved name "." indicates the working directory parent. If no
       working directory is checked out, it is equivalent to null. If an
       uncommitted merge is in progress, "." is the revision of the first
       parent.

SPECIFYING REVISION SETS         top

       Mercurial supports a functional language for selecting a set of
       revisions.
       The language supports a number of predicates which are joined by
       infix operators. Parenthesis can be used for grouping.
       Identifiers such as branch names may need quoting with single or
       double quotes if they contain characters like - or if they match one
       of the predefined predicates.
       Special characters can be used in quoted identifiers by escaping
       them, e.g., \n is interpreted as a newline. To prevent them from
       being interpreted, strings can be prefixed with r, e.g. r'...'.
       There is a single prefix operator:
       not x
              Changesets not in x. Short form is ! x.
       These are the supported infix operators:
       x::y
              A DAG range, meaning all changesets that are descendants of x
              and ancestors of y, including x and y themselves. If the first
              endpoint is left out, this is equivalent to ancestors(y), if
              the second is left out it is equivalent to descendants(x).
              An alternative syntax is x..y.
       x:y
              All changesets with revision numbers between x and y, both
              inclusive. Either endpoint can be left out, they default to 0
              and tip.
       x and y
              The intersection of changesets in x and y. Short form is x &
              y.
       x or y
              The union of changesets in x and y. There are two alternative
              short forms: x | y and x + y.
       x - y
              Changesets in x but not in y.
       x^n
              The nth parent of x, n == 0, 1, or 2.  For n == 0, x; for n ==
              1, the first parent of each changeset in x; for n == 2, the
              second parent of changeset in x.
       x~n
              The nth first ancestor of x; x~0 is x; x~3 is x^^^.
       There is a single postfix operator:
       x^
              Equivalent to x^1, the first parent of each changeset in x.
       The following predicates are supported:
       adds(pattern)
              Changesets that add a file matching pattern.
       all()
              All changesets, the same as 0:tip.
       ancestor(*changeset)
              Greatest common ancestor of the changesets.
              Accepts 0 or more changesets.  Will return empty list when
              passed no args.  Greatest common ancestor of a single
              changeset is that changeset.
       ancestors(set)
              Changesets that are ancestors of a changeset in set.
       author(string)
              Alias for user(string).
       bisect(string)
              Changesets marked in the specified bisect status:
              · good, bad, skip: csets explicitly marked as good/bad/skip
              · goods, bads      : csets topologically good/bad
              · range              : csets taking part in the bisection
              · pruned             : csets that are goods, bads or skipped
              · untested           : csets whose fate is yet unknown
              · ignored            : csets ignored due to DAG topology
              · current            : the cset currently being bisected
       bookmark([name])
              The named bookmark or all bookmarks.
              If name starts with re:, the remainder of the name is treated
              as a regular expression. To match a bookmark that actually
              starts with re:, use the prefix literal:.
       branch(string or set)
              All changesets belonging to the given branch or the branches
              of the given changesets.
              If string starts with re:, the remainder of the name is
              treated as a regular expression. To match a branch that
              actually starts with re:, use the prefix literal:.
       branchpoint()
              Changesets with more than one child.
       bumped()
              Mutable changesets marked as successors of public changesets.
              Only non-public and non-obsolete changesets can be bumped.
       bundle()
              Changesets in the bundle.
              Bundle must be specified by the -R option.
       children(set)
              Child changesets of changesets in set.
       closed()
              Changeset is closed.
       contains(pattern)
              Revision contains a file matching pattern. See hg help
              patterns for information about file patterns.
       converted([id])
              Changesets converted from the given identifier in the old
              repository if present, or all converted changesets if no
              identifier is specified.
       date(interval)
              Changesets within the interval, see hg help dates.
       desc(string)
              Search commit message for string. The match is
              case-insensitive.
       descendants(set)
              Changesets which are descendants of changesets in set.
       destination([set])
              Changesets that were created by a graft, transplant or rebase
              operation, with the given revisions specified as the source.
              Omitting the optional set is the same as passing all().
       divergent()
              Final successors of changesets with an alternative set of
              final successors.
       draft()
              Changeset in draft phase.
       extinct()
              Obsolete changesets with obsolete descendants only.
       extra(label, [value])
              Changesets with the given label in the extra metadata, with
              the given optional value.
              If value starts with re:, the remainder of the value is
              treated as a regular expression. To match a value that
              actually starts with re:, use the prefix literal:.
       file(pattern)
              Changesets affecting files matched by pattern.
              For a faster but less accurate result, consider using
              filelog() instead.
       filelog(pattern)
              Changesets connected to the specified filelog.
              For performance reasons, filelog() does not show every
              changeset that affects the requested file(s). See hg help log
              for details. For a slower, more accurate result, use file().
       first(set, [n])
              An alias for limit().
       follow([file])
              An alias for ::. (ancestors of the working copy's first
              parent).  If a filename is specified, the history of the given
              file is followed, including copies.
       grep(regex)
              Like keyword(string) but accepts a regex. Use grep(r'...') to
              ensure special escape characters are handled correctly. Unlike
              keyword(string), the match is case-sensitive.
       head()
              Changeset is a named branch head.
       heads(set)
              Members of set with no children in set.
       hidden()
              Hidden changesets.
       id(string)
              Revision non-ambiguously specified by the given hex string
              prefix.
       keyword(string)
              Search commit message, user name, and names of changed files
              for string. The match is case-insensitive.
       last(set, [n])
              Last n members of set, defaulting to 1.
       limit(set, [n])
              First n members of set, defaulting to 1.
       matching(revision [, field])
              Changesets in which a given set of fields match the set of
              fields in the selected revision or set.
              To match more than one field pass the list of fields to match
              separated by spaces (e.g. author description).
              Valid fields are most regular revision fields and some special
              fields.
              Regular revision fields are description, author, branch, date,
              files, phase, parents, substate, user and diff.  Note that
              author and user are synonyms. diff refers to the contents of
              the revision. Two revisions matching their diff will also
              match their files.
              Special fields are summary and metadata: summary matches the
              first line of the description.  metadata is equivalent to
              matching description user date (i.e. it matches the main
              metadata fields).
              metadata is the default field which is used when no fields are
              specified. You can match more than one field at a time.
       max(set)
              Changeset with highest revision number in set.
       merge()
              Changeset is a merge changeset.
       min(set)
              Changeset with lowest revision number in set.
       modifies(pattern)
              Changesets modifying files matched by pattern.
       obsolete()
              Mutable changeset with a newer version.
       origin([set])
              Changesets that were specified as a source for the grafts,
              transplants or rebases that created the given revisions.
              Omitting the optional set is the same as passing all().  If a
              changeset created by these operations is itself specified as a
              source for one of these operations, only the source changeset
              for the first operation is selected.
       outgoing([path])
              Changesets not found in the specified destination repository,
              or the default push location.
       p1([set])
              First parent of changesets in set, or the working directory.
       p2([set])
              Second parent of changesets in set, or the working directory.
       parents([set])
              The set of all parents for all changesets in set, or the
              working directory.
       present(set)
              An empty set, if any revision in set isn't found; otherwise,
              all revisions in set.
              If any of specified revisions is not present in the local
              repository, the query is normally aborted. But this predicate
              allows the query to continue even in such cases.
       public()
              Changeset in public phase.
       remote([id [,path]])
              Local revision that corresponds to the given identifier in a
              remote repository, if present. Here, the '.' identifier is a
              synonym for the current local branch.
       removes(pattern)
              Changesets which remove files matching pattern.
       rev(number)
              Revision with the given numeric identifier.
       reverse(set)
              Reverse order of set.
       roots(set)
              Changesets in set with no parent changeset in set.
       secret()
              Changeset in secret phase.
       sort(set[, [-]key...])
              Sort set by keys. The default sort order is ascending, specify
              a key as -key to sort in descending order.
              The keys can be:
              · rev for the revision number,
              · branch for the branch name,
              · desc for the commit message (description),
              · user for user name (author can be used as an alias),
              · date for the commit date
       tag([name])
              The specified tag by name, or all tagged revisions if no name
              is given.
       unstable()
              Non-obsolete changesets with obsolete ancestors.
       user(string)
              User name contains string. The match is case-insensitive.
              If string starts with re:, the remainder of the string is
              treated as a regular expression. To match a user that actually
              contains re:, use the prefix literal:.
       New predicates (known as "aliases") can be defined, using any
       combination of existing predicates or other aliases. An alias
       definition looks like:
       <alias> = <definition>
       in the revsetalias section of a Mercurial configuration file.
       Arguments of the form $1, $2, etc. are substituted from the alias
       into the definition.
       For example,
       [revsetalias]
       h = heads()
       d($1) = sort($1, date)
       rs($1, $2) = reverse(sort($1, $2))
       defines three aliases, h, d, and rs. rs(0:tip, author) is exactly
       equivalent to reverse(sort(0:tip, author)).
       Command line equivalents for hg log:
       -f    ->  ::.
       -d x  ->  date(x)
       -k x  ->  keyword(x)
       -m    ->  merge()
       -u x  ->  user(x)
       -b x  ->  branch(x)
       -P x  ->  !::x
       -l x  ->  limit(expr, x)
       Some sample queries:
       · Changesets on the default branch:
         hg log -r "branch(default)"
       · Changesets on the default branch since tag 1.5 (excluding merges):
         hg log -r "branch(default) and 1.5:: and not merge()"
       · Open branch heads:
         hg log -r "head() and not closed()"
       · Changesets between tags 1.3 and 1.5 mentioning "bug" that affect
         hgext/*:
         hg log -r "1.3::1.5 and keyword(bug) and file('hgext/*')"
       · Changesets committed in May 2008, sorted by user:
         hg log -r "sort(date('May 2008'), user)"
       · Changesets mentioning "bug" or "issue" that are not in a tagged
         release:
         hg log -r "(keyword(bug) or keyword(issue)) and not ancestors(tag())"

SUBREPOSITORIES         top

       Subrepositories let you nest external repositories or projects into a
       parent Mercurial repository, and make commands operate on them as a
       group.
       Mercurial currently supports Mercurial, Git, and Subversion
       subrepositories.
       Subrepositories are made of three components:
       1. Nested repository checkouts. They can appear anywhere in the
          parent working directory.
       2. Nested repository references. They are defined in .hgsub, which
          should be placed in the root of working directory, and tell where
          the subrepository checkouts come from. Mercurial subrepositories
          are referenced like:
          path/to/nested = https://example.com/nested/repo/path
          Git and Subversion subrepos are also supported:
          path/to/nested = [git]git://example.com/nested/repo/path
          path/to/nested = [svn]https://example.com/nested/trunk/path
          where path/to/nested is the checkout location relatively to the
          parent Mercurial root, and https://example.com/nested/repo/path is
          the source repository path. The source can also reference a
          filesystem path.
          Note that .hgsub does not exist by default in Mercurial
          repositories, you have to create and add it to the parent
          repository before using subrepositories.
       3. Nested repository states. They are defined in .hgsubstate, which
          is placed in the root of working directory, and capture whatever
          information is required to restore the subrepositories to the
          state they were committed in a parent repository changeset.
          Mercurial automatically record the nested repositories states when
          committing in the parent repository.
       Note
          The .hgsubstate file should not be edited manually.
   Adding a Subrepository
       If .hgsub does not exist, create it and add it to the parent
       repository. Clone or checkout the external projects where you want it
       to live in the parent repository. Edit .hgsub and add the
       subrepository entry as described above. At this point, the
       subrepository is tracked and the next commit will record its state in
       .hgsubstate and bind it to the committed changeset.
   Synchronizing a Subrepository
       Subrepos do not automatically track the latest changeset of their
       sources. Instead, they are updated to the changeset that corresponds
       with the changeset checked out in the top-level changeset. This is so
       developers always get a consistent set of compatible code and
       libraries when they update.
       Thus, updating subrepos is a manual process. Simply check out target
       subrepo at the desired revision, test in the top-level repo, then
       commit in the parent repository to record the new combination.
   Deleting a Subrepository
       To remove a subrepository from the parent repository, delete its
       reference from .hgsub, then remove its files.
   Interaction with Mercurial Commands
       add    add does not recurse in subrepos unless -S/--subrepos is
              specified.  However, if you specify the full path of a file in
              a subrepo, it will be added even without -S/--subrepos
              specified.  Git and Subversion subrepositories are currently
              silently ignored.
       archive
              archive does not recurse in subrepositories unless
              -S/--subrepos is specified.
       commit commit creates a consistent snapshot of the state of the
              entire project and its subrepositories. If any subrepositories
              have been modified, Mercurial will abort.  Mercurial can be
              made to instead commit all modified subrepositories by
              specifying -S/--subrepos, or setting "ui.commitsubrepos=True"
              in a configuration file (see hg help config).  After there are
              no longer any modified subrepositories, it records their state
              and finally commits it in the parent repository.
       diff   diff does not recurse in subrepos unless -S/--subrepos is
              specified. Changes are displayed as usual, on the
              subrepositories elements. Git and Subversion subrepositories
              are currently silently ignored.
       forget forget currently only handles exact file matches in subrepos.
              Git and Subversion subrepositories are currently silently
              ignored.
       incoming
              incoming does not recurse in subrepos unless -S/--subrepos is
              specified. Git and Subversion subrepositories are currently
              silently ignored.
       outgoing
              outgoing does not recurse in subrepos unless -S/--subrepos is
              specified. Git and Subversion subrepositories are currently
              silently ignored.
       pull   pull is not recursive since it is not clear what to pull prior
              to running hg update. Listing and retrieving all
              subrepositories changes referenced by the parent repository
              pulled changesets is expensive at best, impossible in the
              Subversion case.
       push   Mercurial will automatically push all subrepositories first
              when the parent repository is being pushed. This ensures new
              subrepository changes are available when referenced by
              top-level repositories.  Push is a no-op for Subversion
              subrepositories.
       status status does not recurse into subrepositories unless
              -S/--subrepos is specified. Subrepository changes are
              displayed as regular Mercurial changes on the subrepository
              elements. Subversion subrepositories are currently silently
              ignored.
       update update restores the subrepos in the state they were originally
              committed in target changeset. If the recorded changeset is
              not available in the current subrepository, Mercurial will
              pull it in first before updating.  This means that updating
              can require network access when using subrepositories.
   Remapping Subrepositories Sources
       A subrepository source location may change during a project life,
       invalidating references stored in the parent repository history. To
       fix this, rewriting rules can be defined in parent repository hgrc
       file or in Mercurial configuration. See the [subpaths] section in
       hgrc(5) for more details.

TEMPLATE USAGE         top

       Mercurial allows you to customize output of commands through
       templates. You can either pass in a template from the command line,
       via the --template option, or select an existing template-style
       (--style).
       You can customize output for any "log-like" command: log, outgoing,
       incoming, tip, parents, heads and glog.
       Five styles are packaged with Mercurial: default (the style used when
       no explicit preference is passed), compact, changelog, phases and
       xml.  Usage:
       $ hg log -r1 --style changelog
       A template is a piece of text, with markup to invoke variable
       expansion:
       $ hg log -r1 --template "{node}\n"
       b56ce7b07c52de7d5fd79fb89701ea538af65746
       Strings in curly braces are called keywords. The availability of
       keywords depends on the exact context of the templater. These
       keywords are usually available for templating a log-like command:
       author String. The unmodified author of the changeset.
       bisect String. The changeset bisection status.
       bookmarks
              List of strings. Any bookmarks associated with the changeset.
       branch String. The name of the branch on which the changeset was
              committed.
       branches
              List of strings. The name of the branch on which the changeset
              was committed. Will be empty if the branch name was default.
       children
              List of strings. The children of the changeset.
       date   Date information. The date when the changeset was committed.
       desc   String. The text of the changeset description.
       diffstat
              String. Statistics of changes with the following format:
              "modified files: +added/-removed lines"
       file_adds
              List of strings. Files added by this changeset.
       file_copies
              List of strings. Files copied in this changeset with their
              sources.
       file_copies_switch
              List of strings. Like "file_copies" but displayed only if the
              --copied switch is set.
       file_dels
              List of strings. Files removed by this changeset.
       file_mods
              List of strings. Files modified by this changeset.
       files  List of strings. All files modified, added, or removed by this
              changeset.
       latesttag
              String. Most recent global tag in the ancestors of this
              changeset.
       latesttagdistance
              Integer. Longest path to the latest tag.
       node   String. The changeset identification hash, as a 40 hexadecimal
              digit string.
       p1node String. The identification hash of the changeset's first
              parent, as a 40 digit hexadecimal string. If the changeset has
              no parents, all digits are 0.
       p1rev  Integer. The repository-local revision number of the
              changeset's first parent, or -1 if the changeset has no
              parents.
       p2node String. The identification hash of the changeset's second
              parent, as a 40 digit hexadecimal string. If the changeset has
              no second parent, all digits are 0.
       p2rev  Integer. The repository-local revision number of the
              changeset's second parent, or -1 if the changeset has no
              second parent.
       parents
              List of strings. The parents of the changeset in "rev:node"
              format. If the changeset has only one "natural" parent (the
              predecessor revision) nothing is shown.
       phase  String. The changeset phase name.
       phaseidx
              Integer. The changeset phase index.
       rev    Integer. The repository-local changeset revision number.
       tags   List of strings. Any tags associated with the changeset.
       The "date" keyword does not produce human-readable output. If you
       want to use a date in your output, you can use a filter to process
       it. Filters are functions which return a string based on the input
       variable. Be sure to use the stringify filter first when you're
       applying a string-input filter to a list-like input variable.  You
       can also use a chain of filters to get the desired output:
       $ hg tip --template "{date|isodate}\n"
       2008-08-21 18:22 +0000
       List of filters:
       addbreaks
              Any text. Add an XHTML "<br />" tag before the end of every
              line except the last.
       age    Date. Returns a human-readable date/time difference between
              the given date/time and the current date/time.
       basename
              Any text. Treats the text as a path, and returns the last
              component of the path after splitting by the path separator
              (ignoring trailing separators). For example, "foo/bar/baz"
              becomes "baz" and "foo/bar//" becomes "bar".
       date   Date. Returns a date in a Unix date format, including the
              timezone: "Mon Sep 04 15:13:13 2006 0700".
       domain Any text. Finds the first string that looks like an email
              address, and extracts just the domain component. Example: User
              <user@example.com> becomes example.com.
       email  Any text. Extracts the first string that looks like an email
              address. Example: User <user@example.com> becomes
              user@example.com.
       emailuser
              Any text. Returns the user portion of an email address.
       escape Any text. Replaces the special XML/XHTML characters "&", "<"
              and ">" with XML entities, and filters out NUL characters.
       fill68 Any text. Wraps the text to fit in 68 columns.
       fill76 Any text. Wraps the text to fit in 76 columns.
       firstline
              Any text. Returns the first line of text.
       hex    Any text. Convert a binary Mercurial node identifier into its
              long hexadecimal representation.
       hgdate Date. Returns the date as a pair of numbers: "1157407993
              25200" (Unix timestamp, timezone offset).
       isodate
              Date. Returns the date in ISO 8601 format: "2009-08-18 13:00
              +0200".
       isodatesec
              Date. Returns the date in ISO 8601 format, including seconds:
              "2009-08-18 13:00:13 +0200". See also the rfc3339date filter.
       localdate
              Date. Converts a date to local date.
       nonempty
              Any text. Returns '(none)' if the string is empty.

              Any text. Returns the input text rendered as a sequence of XML
              entities.
       person Any text. Returns the name before an email address,
              interpreting it as per RFC 5322.
       rfc3339date
              Date. Returns a date using the Internet date format specified
              in RFC 3339: "2009-08-18T13:00:13+02:00".
       rfc822date
              Date. Returns a date using the same format used in email
              headers: "Tue, 18 Aug 2009 13:00:13 +0200".
       short  Changeset hash. Returns the short form of a changeset hash,
              i.e. a 12 hexadecimal digit string.
       shortbisect
              Any text. Treats text as a bisection status, and returns a
              single-character representing the status (G: good, B: bad, S:
              skipped, U: untested, I: ignored). Returns single space if
              text is not a valid bisection status.
       shortdate
              Date. Returns a date like "2006-09-18".
       stringify
              Any type. Turns the value into text by converting values into
              text and concatenating them.
       strip  Any text. Strips all leading and trailing whitespace.
       stripdir
              Treat the text as path and strip a directory level, if
              possible. For example, "foo" and "foo/bar" becomes "foo".
       tabindent
              Any text. Returns the text, with every line except the first
              starting with a tab character.
       urlescape
              Any text. Escapes all "special" characters. For example, "foo
              bar" becomes "foo%20bar".
       user   Any text. Returns a short representation of a user name or
              email address.
       Note that a filter is nothing more than a function call, i.e.
       expr|filter is equivalent to filter(expr).
       In addition to filters, there are some basic built-in functions:
       · date(date[, fmt])
       · fill(text[, width])
       · get(dict, key)
       · if(expr, then[, else])
       · ifeq(expr, expr, then[, else])
       · join(list, sep)
       · label(label, expr)
       · sub(pat, repl, expr)
       · rstdoc(text, style)
       Also, for any expression that returns a list, there is a list
       operator:
       · expr % "{template}"
       Some sample command line templates:
       · Format lists, e.g. files:
         $ hg log -r 0 --template "files:\n{files % '  {file}\n'}"
       · Join the list of files with a ", ":
         $ hg log -r 0 --template "files: {join(files, ', ')}\n"
       · Format date:
         $ hg log -r 0 --template "{date(date, '%Y')}\n"
       · Output the description set to a fill-width of 30:
         $ hg log -r 0 --template "{fill(desc, '30')}"
       · Use a conditional to test for the default branch:
         $ hg log -r 0 --template "{ifeq(branch, 'default', 'on the main branch',
         'on branch {branch}')}\n"
       · Append a newline if not empty:
         $ hg tip --template "{if(author, '{author}\n')}"
       · Label the output for use with the color extension:
         $ hg log -r 0 --template "{label('changeset.{phase}', node|short)}\n"
       · Invert the firstline filter, i.e. everything but the first line:
         $ hg log -r 0 --template "{sub(r'^.*\n?\n?', '', desc)}\n"

URL PATHS         top

       Valid URLs are of the form:
       local/filesystem/path[#revision]
       file://local/filesystem/path[#revision]
       http://[user[:pass]@]host[:port]/[path][#revision]
       https://[user[:pass]@]host[:port]/[path][#revision]
       ssh://[user@]host[:port]/[path][#revision]
       Paths in the local filesystem can either point to Mercurial
       repositories or to bundle files (as created by hg bundle or :hg:`
       incoming --bundle`). See also hg help paths.
       An optional identifier after # indicates a particular branch, tag, or
       changeset to use from the remote repository. See also hg help
       revisions.
       Some features, such as pushing to http:// and https:// URLs are only
       possible if the feature is explicitly enabled on the remote Mercurial
       server.
       Note that the security of HTTPS URLs depends on proper configuration
       of web.cacerts.
       Some notes about using SSH with Mercurial:
       · SSH requires an accessible shell account on the destination machine
         and a copy of hg in the remote path or specified with as remotecmd.
       · path is relative to the remote user's home directory by default.
         Use an extra slash at the start of a path to specify an absolute
         path:
         ssh://example.com//tmp/repository
       · Mercurial doesn't use its own compression via SSH; the right thing
         to do is to configure it in your ~/.ssh/config, e.g.:
         Host *.mylocalnetwork.example.com
           Compression no
         Host *
           Compression yes
         Alternatively specify "ssh -C" as your ssh command in your
         configuration file or with the --ssh command line option.
       These URLs can all be stored in your configuration file with path
       aliases under the [paths] section like so:
       [paths]
       alias1 = URL1
       alias2 = URL2
       ...
       You can then use the alias for any command that uses a URL (for
       example hg pull alias1 will be treated as hg pull URL1).
       Two path aliases are special because they are used as defaults when
       you do not provide the URL to a command:
       default:
              When you create a repository with hg clone, the clone command
              saves the location of the source repository as the new
              repository's 'default' path. This is then used when you omit
              path from push- and pull-like commands (including incoming and
              outgoing).
       default-push:
              The push command will look for a path named 'default-push',
              and prefer it over 'default' if both are defined.

EXTENSIONS         top

       This section contains help for extensions that are distributed
       together with Mercurial. Help for other extensions is available in
       the help system.
   acl
       hooks for controlling repository access
       This hook makes it possible to allow or deny write access to given
       branches and paths of a repository when receiving incoming changesets
       via pretxnchangegroup and pretxncommit.
       The authorization is matched based on the local user name on the
       system where the hook runs, and not the committer of the original
       changeset (since the latter is merely informative).
       The acl hook is best used along with a restricted shell like hgsh,
       preventing authenticating users from doing anything other than
       pushing or pulling. The hook is not safe to use if users have
       interactive shell access, as they can then disable the hook. Nor is
       it safe if remote users share an account, because then there is no
       way to distinguish them.
       The order in which access checks are performed is:
       1. Deny  list for branches (section acl.deny.branches)
       2. Allow list for branches (section acl.allow.branches)
       3. Deny  list for paths    (section acl.deny)
       4. Allow list for paths    (section acl.allow)
       The allow and deny sections take key-value pairs.
   Branch-based Access Control
       Use the acl.deny.branches and acl.allow.branches sections to have
       branch-based access control. Keys in these sections can be either:
       · a branch name, or
       · an asterisk, to match any branch;
       The corresponding values can be either:
       · a comma-separated list containing users and groups, or
       · an asterisk, to match anyone;
       You can add the "!" prefix to a user or group name to invert the
       sense of the match.
   Path-based Access Control
       Use the acl.deny and acl.allow sections to have path-based access
       control. Keys in these sections accept a subtree pattern (with a glob
       syntax by default). The corresponding values follow the same syntax
       as the other sections above.
   Groups
       Group names must be prefixed with an @ symbol. Specifying a group
       name has the same effect as specifying all the users in that group.
       You can define group members in the acl.groups section.  If a group
       name is not defined there, and Mercurial is running under a Unix-like
       system, the list of users will be taken from the OS.  Otherwise, an
       exception will be raised.
   Example Configuration
       [hooks]
       # Use this if you want to check access restrictions at commit time
       pretxncommit.acl = python:hgext.acl.hook
       # Use this if you want to check access restrictions for pull, push,
       # bundle and serve.
       pretxnchangegroup.acl = python:hgext.acl.hook
       [acl]
       # Allow or deny access for incoming changes only if their source is
       # listed here, let them pass otherwise. Source is "serve" for all
       # remote access (http or ssh), "push", "pull" or "bundle" when the
       # related commands are run locally.
       # Default: serve
       sources = serve
       [acl.deny.branches]
       # Everyone is denied to the frozen branch:
       frozen-branch = *
       # A bad user is denied on all branches:
       * = bad-user
       [acl.allow.branches]
       # A few users are allowed on branch-a:
       branch-a = user-1, user-2, user-3
       # Only one user is allowed on branch-b:
       branch-b = user-1
       # The super user is allowed on any branch:
       * = super-user
       # Everyone is allowed on branch-for-tests:
       branch-for-tests = *
       [acl.deny]
       # This list is checked first. If a match is found, acl.allow is not
       # checked. All users are granted access if acl.deny is not present.
       # Format for both lists: glob pattern = user, ..., @group, ...
       # To match everyone, use an asterisk for the user:
       # my/glob/pattern = *
       # user6 will not have write access to any file:
       ** = user6
       # Group "hg-denied" will not have write access to any file:
       ** = @hg-denied
       # Nobody will be able to change "DONT-TOUCH-THIS.txt", despite
       # everyone being able to change all other files. See below.
       src/main/resources/DONT-TOUCH-THIS.txt = *
       [acl.allow]
       # if acl.allow is not present, all users are allowed by default
       # empty acl.allow = no users allowed
       # User "doc_writer" has write access to any file under the "docs"
       # folder:
       docs/** = doc_writer
       # User "jack" and group "designers" have write access to any file
       # under the "images" folder:
       images/** = jack, @designers
       # Everyone (except for "user6" and "@hg-denied" - see acl.deny above)
       # will have write access to any file under the "resources" folder
       # (except for 1 file. See acl.deny):
       src/main/resources/** = *
       .hgtags = release_engineer
   Examples using the ! prefix
       Suppose there's a branch that only a given user (or group) should be
       able to push to, and you don't want to restrict access to any other
       branch that may be created.
       The "!" prefix allows you to prevent anyone except a given user or
       group to push changesets in a given branch or path.
       In the examples below, we will: 1) Deny access to branch "ring" to
       anyone but user "gollum" 2) Deny access to branch "lake" to anyone
       but members of the group "hobbit" 3) Deny access to a file to anyone
       but user "gollum"
       [acl.allow.branches]
       # Empty
       [acl.deny.branches]
       # 1) only 'gollum' can commit to branch 'ring';
       # 'gollum' and anyone else can still commit to any other branch.
       ring = !gollum
       # 2) only members of the group 'hobbit' can commit to branch 'lake';
       # 'hobbit' members and anyone else can still commit to any other branch.
       lake = !@hobbit
       # You can also deny access based on file paths:
       [acl.allow]
       # Empty
       [acl.deny]
       # 3) only 'gollum' can change the file below;
       # 'gollum' and anyone else can still change any other file.
       /misty/mountains/cave/ring = !gollum
   blackbox
       log repository events to a blackbox for debugging
       Logs event information to .hg/blackbox.log to help debug and diagnose
       problems.  The events that get logged can be configured via the
       blackbox.track config key.  Examples:
       [blackbox]
       track = *
       [blackbox]
       track = command, commandfinish, commandexception, exthook, pythonhook
       [blackbox]
       track = incoming
       [blackbox]
       # limit the size of a log file
       maxsize = 1.5 MB
       # rotate up to N log files when the current one gets too big
       maxfiles = 3
   Commands
   blackbox
       hg blackbox [OPTION]...
       view the recent repository events
       Options:
       -l, --limit
              the number of events to show (default: 10)
   bugzilla
       hooks for integrating with the Bugzilla bug tracker
       This hook extension adds comments on bugs in Bugzilla when changesets
       that refer to bugs by Bugzilla ID are seen. The comment is formatted
       using the Mercurial template mechanism.
       The bug references can optionally include an update for Bugzilla of
       the hours spent working on the bug. Bugs can also be marked fixed.
       Three basic modes of access to Bugzilla are provided:
       1. Access via the Bugzilla XMLRPC interface. Requires Bugzilla 3.4 or
          later.
       2. Check data via the Bugzilla XMLRPC interface and submit bug change
          via email to Bugzilla email interface. Requires Bugzilla 3.4 or
          later.
       3. Writing directly to the Bugzilla database. Only Bugzilla
          installations using MySQL are supported. Requires Python MySQLdb.
       Writing directly to the database is susceptible to schema changes,
       and relies on a Bugzilla contrib script to send out bug change
       notification emails. This script runs as the user running Mercurial,
       must be run on the host with the Bugzilla install, and requires
       permission to read Bugzilla configuration details and the necessary
       MySQL user and password to have full access rights to the Bugzilla
       database. For these reasons this access mode is now considered
       deprecated, and will not be updated for new Bugzilla versions going
       forward. Only adding comments is supported in this access mode.
       Access via XMLRPC needs a Bugzilla username and password to be
       specified in the configuration. Comments are added under that
       username. Since the configuration must be readable by all Mercurial
       users, it is recommended that the rights of that user are restricted
       in Bugzilla to the minimum necessary to add comments. Marking bugs
       fixed requires Bugzilla 4.0 and later.
       Access via XMLRPC/email uses XMLRPC to query Bugzilla, but sends
       email to the Bugzilla email interface to submit comments to bugs.
       The From: address in the email is set to the email address of the
       Mercurial user, so the comment appears to come from the Mercurial
       user. In the event that the Mercurial user email is not recognized by
       Bugzilla as a Bugzilla user, the email associated with the Bugzilla
       username used to log into Bugzilla is used instead as the source of
       the comment. Marking bugs fixed works on all supported Bugzilla
       versions.
       Configuration items common to all access modes:
       bugzilla.version
              The access type to use. Values recognized are:
              xmlrpc
                     Bugzilla XMLRPC interface.
              xmlrpc+email
                     Bugzilla XMLRPC and email interfaces.
              3.0
                     MySQL access, Bugzilla 3.0 and later.
              2.18
                     MySQL access, Bugzilla 2.18 and up to but not including
                     3.0.
              2.16
                     MySQL access, Bugzilla 2.16 and up to but not including
                     2.18.
       bugzilla.regexp
              Regular expression to match bug IDs for update in changeset
              commit message.  It must contain one "()" named group <ids>
              containing the bug IDs separated by non-digit characters. It
              may also contain a named group <hours> with a floating-point
              number giving the hours worked on the bug. If no named groups
              are present, the first "()" group is assumed to contain the
              bug IDs, and work time is not updated. The default expression
              matches Bug 1234, Bug no. 1234, Bug number 1234, Bugs
              1234,5678, Bug 1234 and 5678 and variations thereof, followed
              by an hours number prefixed by h or hours, e.g. hours 1.5.
              Matching is case insensitive.
       bugzilla.fixregexp
              Regular expression to match bug IDs for marking fixed in
              changeset commit message. This must contain a "()" named group
              <ids>` containing the bug IDs separated by non-digit
              characters. It may also contain a named group ``<hours> with a
              floating-point number giving the hours worked on the bug. If
              no named groups are present, the first "()" group is assumed
              to contain the bug IDs, and work time is not updated. The
              default expression matches Fixes 1234, Fixes bug 1234, Fixes
              bugs 1234,5678, Fixes 1234 and 5678 and variations thereof,
              followed by an hours number prefixed by h or hours, e.g. hours
              1.5. Matching is case insensitive.
       bugzilla.fixstatus
              The status to set a bug to when marking fixed. Default
              RESOLVED.
       bugzilla.fixresolution
              The resolution to set a bug to when marking fixed. Default
              FIXED.
       bugzilla.style
              The style file to use when formatting comments.
       bugzilla.template
              Template to use when formatting comments. Overrides style if
              specified. In addition to the usual Mercurial keywords, the
              extension specifies:
              {bug}
                     The Bugzilla bug ID.
              {root}
                     The full pathname of the Mercurial repository.
              {webroot}
                     Stripped pathname of the Mercurial repository.
              {hgweb}
                     Base URL for browsing Mercurial repositories.
              Default changeset {node|short} in repo {root} refers to bug
              {bug}.\ndetails:\n\t{desc|tabindent}
       bugzilla.strip
              The number of path separator characters to strip from the
              front of the Mercurial repository path ({root} in templates)
              to produce {webroot}. For example, a repository with {root}
              /var/local/my-project with a strip of 2 gives a value for
              {webroot} of my-project. Default 0.
       web.baseurl
              Base URL for browsing Mercurial repositories. Referenced from
              templates as {hgweb}.
       Configuration items common to XMLRPC+email and MySQL access modes:
       bugzilla.usermap
              Path of file containing Mercurial committer email to Bugzilla
              user email mappings. If specified, the file should contain one
              mapping per line:
              committer = Bugzilla user
              See also the [usermap] section.
       The [usermap] section is used to specify mappings of Mercurial
       committer email to Bugzilla user email. See also bugzilla.usermap.
       Contains entries of the form committer = Bugzilla user.
       XMLRPC access mode configuration:
       bugzilla.bzurl
              The base URL for the Bugzilla installation.  Default
              http://localhost/bugzilla .
       bugzilla.user
              The username to use to log into Bugzilla via XMLRPC. Default
              bugs.
       bugzilla.password
              The password for Bugzilla login.
       XMLRPC+email access mode uses the XMLRPC access mode configuration
       items, and also:
       bugzilla.bzemail
              The Bugzilla email address.
       In addition, the Mercurial email settings must be configured. See the
       documentation in hgrc(5), sections [email] and [smtp].
       MySQL access mode configuration:
       bugzilla.host
              Hostname of the MySQL server holding the Bugzilla database.

              Name of the Bugzilla database in MySQL. Default bugs.
       bugzilla.user
              Username to use to access MySQL server. Default bugs.
       bugzilla.password
              Password to use to access MySQL server.
       bugzilla.timeout
              Database connection timeout (seconds). Default 5.
       bugzilla.bzuser
              Fallback Bugzilla user name to record comments with, if
              changeset committer cannot be found as a Bugzilla user.
       bugzilla.bzdir
              Bugzilla install directory. Used by default notify. Default
              /var/www/html/bugzilla.
       bugzilla.notify
              The command to run to get Bugzilla to send bug change
              notification emails. Substitutes from a map with 3 keys,
              bzdir, id (bug id) and user (committer bugzilla email).
              Default depends on version; from 2.18 it is "cd %(bzdir)s &&
              perl -T contrib/sendbugmail.pl %(id)s %(user)s".

       Print the children of the working directory's revisions. If a
       revision is given via -r/--rev, the children of that revision will be
       printed. If a file argument is given, revision in which the file was
       last changed (after the working directory revision or the argument to
       --rev if given) is printed.
       Options:
       -r, --rev
              show children of the specified revision
       --style
              display using template map file
       --template
              display with template
   churn
       command to display statistics about repository history
   Commands
   churn
       hg churn [-d DATE] [-r REV] [--aliases FILE] [FILE]
       This command will display a histogram representing the number of
       changed lines or revisions, grouped according to the given template.
       The default template will group changes by author.  The --dateformat
       option may be used to group the results by date instead.
       Statistics are based on the number of changed lines, or alternatively
       the number of matching revisions if the --changesets option is
       specified.
       Examples:
       # display count of changed lines for every committer
       hg churn -t '{author|email}'
       # display daily activity graph
       hg churn -f '%H' -s -c
       # display activity of developers by month
       hg churn -f '%Y-%m' -s -c
       # display count of lines changed in every year
       hg churn -f '%Y' -s
       It is possible to map alternate email addresses to a main address by
       providing a file using the following format:
       <alias email> = <actual email>
       Such a file may be specified with the --aliases option, otherwise a
       .hgchurn file will be looked for in the working directory root.
       Options:
       -r, --rev
              count rate for the specified revision or range
       -d, --date
              count rate for revisions matching date spec
       -t, --template
              template to group changesets (default: {author|email})
       -f, --dateformat
              strftime-compatible format for grouping by date
       -c, --changesets
              count rate by number of changesets
       -s, --sort
              sort by key (default: sort by count)
       --diffstat
              display added/removed lines separately
       --aliases
              file with email aliases
       -I, --include
              include names matching the given patterns
       -X, --exclude
              exclude names matching the given patterns
   color
       colorize output from some commands
       This extension modifies the status and resolve commands to add color
       to their output to reflect file status, the qseries command to add
       color to reflect patch status (applied, unapplied, missing), and to
       diff-related commands to highlight additions, removals, diff headers,
       and trailing whitespace.
       Other effects in addition to color, like bold and underlined text,
       are also available. By default, the terminfo database is used to find
       the terminal codes used to change color and effect.  If terminfo is
       not available, then effects are rendered with the ECMA-48 SGR control
       function (aka ANSI escape codes).
       Default effects may be overridden from your configuration file:
       [color]
       status.modified = blue bold underline red_background
       status.added = green bold
       status.removed = red bold blue_background
       status.deleted = cyan bold underline
       status.unknown = magenta bold underline
       status.ignored = black bold
       # 'none' turns off all effects
       status.clean = none
       status.copied = none
       qseries.applied = blue bold underline
       qseries.unapplied = black bold
       qseries.missing = red bold
       diff.diffline = bold
       diff.extended = cyan bold
       diff.file_a = red bold
       diff.file_b = green bold
       diff.hunk = magenta
       diff.deleted = red
       diff.inserted = green
       diff.changed = white
       diff.trailingwhitespace = bold red_background
       resolve.unresolved = red bold
       resolve.resolved = green bold
       bookmarks.current = green
       branches.active = none
       branches.closed = black bold
       branches.current = green
       branches.inactive = none
       tags.normal = green
       tags.local = black bold
       The available effects in terminfo mode are 'blink', 'bold', 'dim',
       'inverse', 'invisible', 'italic', 'standout', and 'underline'; in
       ECMA-48 mode, the options are 'bold', 'inverse', 'italic', and
       'underline'.  How each is rendered depends on the terminal emulator.
       Some may not be available for a given terminal type, and will be
       silently ignored.
       Note that on some systems, terminfo mode may cause problems when
       using color with the pager extension and less -R. less with the -R
       option will only display ECMA-48 color codes, and terminfo mode may
       sometimes emit codes that less doesn't understand. You can work
       around this by either using ansi mode (or auto mode), or by using
       less -r (which will pass through all terminal control codes, not just
       color control codes).
       Because there are only eight standard colors, this module allows you
       to define color names for other color slots which might be available
       for your terminal type, assuming terminfo mode.  For instance:
       color.brightblue = 12
       color.pink = 207
       color.orange = 202
       to set 'brightblue' to color slot 12 (useful for 16 color terminals
       that have brighter colors defined in the upper eight) and, 'pink' and
       'orange' to colors in 256-color xterm's default color cube.  These
       defined colors may then be used as any of the pre-defined eight,
       including appending '_background' to set the background to that
       color.
       By default, the color extension will use ANSI mode (or win32 mode on
       Windows) if it detects a terminal. To override auto mode (to enable
       terminfo mode, for example), set the following configuration option:
       [color]
       mode = terminfo
       Any value other than 'ansi', 'win32', 'terminfo', or 'auto' will
       disable color.
   convert
       import revisions from foreign VCS repositories into Mercurial
   Commands
   convert
       hg convert [OPTION]... SOURCE [DEST [REVMAP]]
       Accepted source formats [identifiers]:
       · Mercurial [hg]
       · CVS [cvs]
       · Darcs [darcs]
       · git [git]
       · Subversion [svn]
       · Monotone [mtn]
       · GNU Arch [gnuarch]
       · Bazaar [bzr]
       · Perforce [p4]
       Accepted destination formats [identifiers]:
       · Mercurial [hg]
       · Subversion [svn] (history on branches is not preserved)
       If no revision is given, all revisions will be converted.  Otherwise,
       convert will only import up to the named revision (given in a format
       understood by the source).
       If no destination directory name is specified, it defaults to the
       basename of the source with -hg appended. If the destination
       repository doesn't exist, it will be created.
       By default, all sources except Mercurial will use --branchsort.
       Mercurial uses --sourcesort to preserve original revision numbers
       order. Sort modes have the following effects:
       --branchsort
              convert from parent to child revision when possible, which
              means branches are usually converted one after the other. It
              generates more compact repositories.
       --datesort
              sort revisions by date. Converted repositories have
              good-looking changelogs but are often an order of magnitude
              larger than the same ones generated by --branchsort.
       --sourcesort
              try to preserve source revisions order, only supported by
              Mercurial sources.
       --closesort
              try to move closed revisions as close as possible to parent
              branches, only supported by Mercurial sources.
       If REVMAP isn't given, it will be put in a default location
       (<dest>/.hg/shamap by default). The REVMAP is a simple text file that
       maps each source commit ID to the destination ID for that revision,
       like so:
       <source ID> <destination ID>
       If the file doesn't exist, it's automatically created. It's updated
       on each commit copied, so hg convert can be interrupted and can be
       run repeatedly to copy new commits.
       The authormap is a simple text file that maps each source commit
       author to a destination commit author. It is handy for source SCMs
       that use unix logins to identify authors (e.g.: CVS). One line per
       author mapping and the line format is:
       source author = destination author
       Empty lines and lines starting with a # are ignored.
       The filemap is a file that allows filtering and remapping of files
       and directories. Each line can contain one of the following
       directives:
       include path/to/file-or-dir
       exclude path/to/file-or-dir
       rename path/to/source path/to/destination
       Comment lines start with #. A specified path matches if it equals the
       full relative name of a file or one of its parent directories. The
       include or exclude directive with the longest matching path applies,
       so line order does not matter.
       The include directive causes a file, or all files under a directory,
       to be included in the destination repository, and the exclusion of
       all other files and directories not explicitly included. The exclude
       directive causes files or directories to be omitted. The rename
       directive renames a file or directory if it is converted. To rename
       from a subdirectory into the root of the repository, use . as the
       path to rename to.
       The splicemap is a file that allows insertion of synthetic history,
       letting you specify the parents of a revision. This is useful if you
       want to e.g. give a Subversion merge two parents, or graft two
       disconnected series of history together. Each entry contains a key,
       followed by a space, followed by one or two comma-separated values:
       key parent1, parent2
       The key is the revision ID in the source revision control system
       whose parents should be modified (same format as a key in
       .hg/shamap). The values are the revision IDs (in either the source or
       destination revision control system) that should be used as the new
       parents for that node. For example, if you have merged "release-1.0"
       into "trunk", then you should specify the revision on "trunk" as the
       first parent and the one on the "release-1.0" branch as the second.
       The branchmap is a file that allows you to rename a branch when it is
       being brought in from whatever external repository. When used in
       conjunction with a splicemap, it allows for a powerful combination to
       help fix even the most badly mismanaged repositories and turn them
       into nicely structured Mercurial repositories. The branchmap contains
       lines of the form:
       original_branch_name new_branch_name
       where "original_branch_name" is the name of the branch in the source
       repository, and "new_branch_name" is the name of the branch is the
       destination repository. No whitespace is allowed in the branch names.
       This can be used to (for instance) move code in one repository from
       "default" to a named branch.
   Mercurial Source
       The Mercurial source recognizes the following configuration options,
       which you can set on the command line with --config:
       convert.hg.ignoreerrors
              ignore integrity errors when reading.  Use it to fix Mercurial
              repositories with missing revlogs, by converting from and to
              Mercurial. Default is False.
       convert.hg.saverev
              store original revision ID in changeset (forces target IDs to
              change). It takes a boolean argument and defaults to False.
       convert.hg.startrev
              convert start revision and its descendants.  It takes a hg
              revision identifier and defaults to 0.
   CVS Source
       CVS source will use a sandbox (i.e. a checked-out copy) from CVS to
       indicate the starting point of what will be converted. Direct access
       to the repository files is not needed, unless of course the
       repository is :local:. The conversion uses the top level directory in
       the sandbox to find the CVS repository, and then uses CVS rlog
       commands to find files to convert. This means that unless a filemap
       is given, all files under the starting directory will be converted,
       and that any directory reorganization in the CVS sandbox is ignored.
       The following options can be used with --config:
       convert.cvsps.cache
              Set to False to disable remote log caching, for testing and
              debugging purposes. Default is True.
       convert.cvsps.fuzz
              Specify the maximum time (in seconds) that is allowed between
              commits with identical user and log message in a single
              changeset. When very large files were checked in as part of a
              changeset then the default may not be long enough.  The
              default is 60.
       convert.cvsps.mergeto
              Specify a regular expression to which commit log messages are
              matched. If a match occurs, then the conversion process will
              insert a dummy revision merging the branch on which this log
              message occurs to the branch indicated in the regex. Default
              is {{mergetobranch ([-\w]+)}}
       convert.cvsps.mergefrom
              Specify a regular expression to which commit log messages are
              matched. If a match occurs, then the conversion process will
              add the most recent revision on the branch indicated in the
              regex as the second parent of the changeset. Default is
              {{mergefrombranch ([-\w]+)}}
       convert.localtimezone
              use local time (as determined by the TZ environment variable)
              for changeset date/times. The default is False (use UTC).
       hooks.cvslog
              Specify a Python function to be called at the end of gathering
              the CVS log. The function is passed a list with the log
              entries, and can modify the entries in-place, or add or delete
              them.
       hooks.cvschangesets
              Specify a Python function to be called after the changesets
              are calculated from the CVS log. The function is passed a list
              with the changeset entries, and can modify the changesets
              in-place, or add or delete them.
       An additional "debugcvsps" Mercurial command allows the builtin
       changeset merging code to be run without doing a conversion. Its
       parameters and output are similar to that of cvsps 2.1. Please see
       the command help for more details.
   Subversion Source
       Subversion source detects classical trunk/branches/tags layouts.  By
       default, the supplied svn://repo/path/ source URL is converted as a
       single branch. If svn://repo/path/trunk exists it replaces the
       default branch. If svn://repo/path/branches exists, its
       subdirectories are listed as possible branches. If
       svn://repo/path/tags exists, it is looked for tags referencing
       converted branches. Default trunk, branches and tags values can be
       overridden with following options. Set them to paths relative to the
       source URL, or leave them blank to disable auto detection.
       The following options can be set with --config:
       convert.svn.branches
              specify the directory containing branches.  The default is
              branches.
       convert.svn.tags
              specify the directory containing tags. The default is tags.
       convert.svn.trunk
              specify the name of the trunk branch. The default is trunk.
       convert.localtimezone
              use local time (as determined by the TZ environment variable)
              for changeset date/times. The default is False (use UTC).
       Source history can be retrieved starting at a specific revision,
       instead of being integrally converted. Only single branch conversions
       are supported.
       convert.svn.startrev
              specify start Subversion revision number.  The default is 0.
   Perforce Source
       The Perforce (P4) importer can be given a p4 depot path or a client
       specification as source. It will convert all files in the source to a
       flat Mercurial repository, ignoring labels, branches and
       integrations. Note that when a depot path is given you then usually
       should specify a target directory, because otherwise the target may
       be named ...-hg.
       It is possible to limit the amount of source history to be converted
       by specifying an initial Perforce revision:
       convert.p4.startrev
              specify initial Perforce revision (a Perforce changelist
              number).
   Mercurial Destination
       The following options are supported:
       convert.hg.clonebranches
              dispatch source branches in separate clones. The default is
              False.
       convert.hg.tagsbranch
              branch name for tag revisions, defaults to default.
       convert.hg.usebranchnames
              preserve branch names. The default is True.
       Options:
       --authors
              username mapping filename (DEPRECATED, use --authormap
              instead)
       -s, --source-type
              source repository type
       -d, --dest-type
              destination repository type
       -r, --rev
              import up to target revision REV
       -A, --authormap
              remap usernames using this file
       --filemap
              remap file names using contents of file
       --splicemap
              splice synthesized history into place
       --branchmap
              change branch names while converting
       --branchsort
              try to sort changesets by branches
       --datesort
              try to sort changesets by date
       --sourcesort
              preserve source changesets order
       --closesort
              try to reorder closed revisions
   eol
       automatically manage newlines in repository files
       This extension allows you to manage the type of line endings (CRLF or
       LF) that are used in the repository and in the local working
       directory. That way you can get CRLF line endings on Windows and LF
       on Unix/Mac, thereby letting everybody use their OS native line
       endings.
       The extension reads its configuration from a versioned .hgeol
       configuration file found in the root of the working copy. The .hgeol
       file use the same syntax as all other Mercurial configuration files.
       It uses two sections, [patterns] and [repository].
       The [patterns] section specifies how line endings should be converted
       between the working copy and the repository. The format is specified
       by a file pattern. The first match is used, so put more specific
       patterns first. The available line endings are LF, CRLF, and BIN.
       Files with the declared format of CRLF or LF are always checked out
       and stored in the repository in that format and files declared to be
       binary (BIN) are left unchanged. Additionally, native is an alias for
       checking out in the platform's default line ending: LF on Unix
       (including Mac OS X) and CRLF on Windows. Note that BIN (do nothing
       to line endings) is Mercurial's default behaviour; it is only needed
       if you need to override a later, more general pattern.
       The optional [repository] section specifies the line endings to use
       for files stored in the repository. It has a single setting, native,
       which determines the storage line endings for files declared as
       native in the [patterns] section. It can be set to LF or CRLF. The
       default is LF. For example, this means that on Windows, files
       configured as native (CRLF by default) will be converted to LF when
       stored in the repository. Files declared as LF, CRLF, or BIN in the
       [patterns] section are always stored as-is in the repository.
       Example versioned .hgeol file:
       [patterns]
       **.py = native
       **.vcproj = CRLF
       **.txt = native
       Makefile = LF
       **.jpg = BIN
       [repository]
       native = LF
       Note   The rules will first apply when files are touched in the
              working copy, e.g. by updating to null and back to tip to
              touch all files.
       The extension uses an optional [eol] section read from both the
       normal Mercurial configuration files and the .hgeol file, with the
       latter overriding the former. You can use that section to control the
       overall behavior. There are three settings:
       · eol.native (default os.linesep) can be set to LF or CRLF to
         override the default interpretation of native for checkout. This
         can be used with hg archive on Unix, say, to generate an archive
         where files have line endings for Windows.
       · eol.only-consistent (default True) can be set to False to make the
         extension convert files with inconsistent EOLs. Inconsistent means
         that there is both CRLF and LF present in the file.  Such files are
         normally not touched under the assumption that they have mixed EOLs
         on purpose.
       · eol.fix-trailing-newline (default False) can be set to True to
         ensure that converted files end with a EOL character (either \n or
         \r\n as per the configured patterns).
       The extension provides cleverencode: and cleverdecode: filters like
       the deprecated win32text extension does. This means that you can
       disable win32text and enable eol and your filters will still work.
       You only need to these filters until you have prepared a .hgeol file.
       The win32text.forbid* hooks provided by the win32text extension have
       been unified into a single hook named eol.checkheadshook. The hook
       will lookup the expected line endings from the .hgeol file, which
       means you must migrate to a .hgeol file first before using the hook.
       eol.checkheadshook only checks heads, intermediate invalid revisions
       will be pushed. To forbid them completely, use the eol.checkallhook
       hook. These hooks are best used as pretxnchangegroup hooks.
       See hg help patterns for more information about the glob patterns
       used.
   extdiff
       command to allow external programs to compare revisions
       The extdiff Mercurial extension allows you to use external programs
       to compare revisions, or revision with working directory. The
       external diff programs are called with a configurable set of options
       and two non-option arguments: paths to directories containing
       snapshots of files to compare.
       The extdiff extension also allows you to configure new diff commands,
       so you do not need to type hg extdiff -p kdiff3 always.
       [extdiff]
       # add new command that runs GNU diff(1) in 'context diff' mode
       cdiff = gdiff -Nprc5
       ## or the old way:
       #cmd.cdiff = gdiff
       #opts.cdiff = -Nprc5
       # add new command called vdiff, runs kdiff3
       vdiff = kdiff3
       # add new command called meld, runs meld (no need to name twice)
       meld =
       # add new command called vimdiff, runs gvimdiff with DirDiff plugin
       # (see http://www.vim.org/scripts/script.php?script_id=102) Non
       # English user, be sure to put "let g:DirDiffDynamicDiffText = 1" in
       # your .vimrc
       vimdiff = gvim -f "+next" \
                 "+execute 'DirDiff' fnameescape(argv(0)) fnameescape(argv(1))"
       Tool arguments can include variables that are expanded at runtime:
       $parent1, $plabel1 - filename, descriptive label of first parent
       $child,   $clabel  - filename, descriptive label of child revision
       $parent2, $plabel2 - filename, descriptive label of second parent
       $root              - repository root
       $parent is an alias for $parent1.
       The extdiff extension will look in your [diff-tools] and
       [merge-tools] sections for diff tool arguments, when none are
       specified in [extdiff].
       [extdiff]
       kdiff3 =
       [diff-tools]
       kdiff3.diffargs=--L1 '$plabel1' --L2 '$clabel' $parent $child
       You can use -I/-X and list of file or directory names like normal hg
       diff command. The extdiff extension makes snapshots of only needed
       files, so running the external diff program will actually be pretty
       fast (at least faster than having to compare the entire tree).
   Commands
   extdiff
       hg extdiff [OPT]... [FILE]...
       Show differences between revisions for the specified files, using an
       external program. The default program used is diff, with default
       options "-Npru".
       To select a different program, use the -p/--program option. The
       program will be passed the names of two directories to compare. To
       pass additional options to the program, use -o/--option. These will
       be passed before the names of the directories to compare.
       When two revision arguments are given, then changes are shown between
       those revisions. If only one revision is specified then that revision
       is compared to the working directory, and, when no revisions are
       specified, the working directory files are compared to its parent.
       Options:
       -p, --program
              comparison program to run
       -o, --option
              pass option to comparison program
       -r, --rev
              revision
       -c, --change
              change made by revision
       -I, --include
              include names matching the given patterns
       -X, --exclude
              exclude names matching the given patterns
   factotum
       http authentication with factotum
       This extension allows the factotum(4) facility on Plan 9 from Bell
       Labs platforms to provide authentication information for HTTP access.
       Configuration entries specified in the auth section as well as
       authentication information provided in the repository URL are fully
       supported. If no prefix is specified, a value of "*" will be assumed.
       By default, keys are specified as:
       proto=pass service=hg prefix=<prefix> user=<username> !password=<password>
       If the factotum extension is unable to read the required key, one
       will be requested interactively.
       A configuration section is available to customize runtime behavior.
       By default, these entries are:
       [factotum]
       executable = /bin/auth/factotum
       mountpoint = /mnt/factotum
       service = hg
       The executable entry defines the full path to the factotum binary.
       The mountpoint entry defines the path to the factotum file service.
       Lastly, the service entry controls the service name used when reading
       keys.
   fetch
       pull, update and merge in one command (DEPRECATED)
   Commands
   fetch
       hg fetch [SOURCE]
       This finds all changes from the repository at the specified path or
       URL and adds them to the local repository.
       If the pulled changes add a new branch head, the head is
       automatically merged, and the result of the merge is committed.
       Otherwise, the working directory is updated to include the new
       changes.
       When a merge is needed, the working directory is first updated to the
       newly pulled changes. Local changes are then merged into the pulled
       changes. To switch the merge order, use --switch-parent.
       See hg help dates for a list of formats valid for -d/--date.
       Returns 0 on success.
       Options:
       -r, --rev

       verify all the signatures there may be for a particular revision
   sign
       hg sign [OPTION]... [REV]...
       If no revision is given, the parent of the working directory is used,
       or tip if no revision is checked out.
       See hg help dates for a list of formats valid for -d/--date.
       Options:
       -l, --local
              make the signature local
       -f, --force

   sigs
       hg sigs
       list signed changesets
   graphlog
       command to view revision graphs from a shell
       This extension adds a --graph option to the incoming, outgoing and
       log commands. When this options is given, an ASCII representation of
       the revision graph is also shown.
   Commands
   glog
       hg glog [OPTION]... [FILE]

   hgcia
       hooks for integrating with the CIA.vc notification service
       This is meant to be run as a changegroup or incoming hook. To
       configure it, set the following options in your hgrc:
       [cia]
       # your registered CIA user name
       user = foo
       # the name of the project in CIA
       project = foo
       # the module (subproject) (optional)
       #module = foo
       # Append a diffstat to the log message (optional)
       #diffstat = False
       # Template to use for log messages (optional)
       #template = {desc}\n{baseurl}{webroot}/rev/{node}-- {diffstat}
       # Style to use (optional)
       #style = foo
       # The URL of the CIA notification service (optional)
       # You can use mailto: URLs to send by email, e.g.
       # mailto:cia@cia.vc
       # Make sure to set email.from if you do this.
       #url = http://cia.vc/
       # print message instead of sending it (optional)
       #test = False
       # number of slashes to strip for url paths
       #strip = 0
       [hooks]
       # one of these:
       changegroup.cia = python:hgcia.hook
       #incoming.cia = python:hgcia.hook
       [web]
       # If you want hyperlinks (optional)
       baseurl = http://server/path/to/repo
   hgk
       browse the repository in a graphical way
       The hgk extension allows browsing the history of a repository in a
       graphical way. It requires Tcl/Tk version 8.4 or later. (Tcl/Tk is
       not distributed with Mercurial.)
       hgk consists of two parts: a Tcl script that does the displaying and
       querying of information, and an extension to Mercurial named hgk.py,
       which provides hooks for hgk to get information. hgk can be found in
       the contrib directory, and the extension is shipped in the hgext
       repository, and needs to be enabled.
       The hg view command will launch the hgk Tcl script. For this command
       to work, hgk must be in your search path. Alternately, you can
       specify the path to hgk in your configuration file:
       [hgk]
       path=/location/of/hgk
       hgk can make use of the extdiff extension to visualize revisions.
       Assuming you had already configured extdiff vdiff command, just add:
       [hgk]
       vdiff=vdiff
       Revisions context menu will now display additional entries to fire
       vdiff on hovered and selected revisions.
   Commands
   view
       hg view [-l LIMIT] [REVRANGE]
       start interactive history viewer
       Options:
       -l, --limit
              limit number of changes displayed
   highlight
       syntax highlighting for hgweb (requires Pygments)
       It depends on the Pygments syntax highlighting library:
       http://pygments.org/
       There is a single configuration option:
       [web]
       pygments_style = <style>
       The default is 'colorful'.
   histedit
       interactive history editing
       With this extension installed, Mercurial gains one new command:
       histedit. Usage is as follows, assuming the following history:
       @  3[tip]   7c2fd3b9020c   2009-04-27 18:04 -0500   durin42
       |    Add delta
       |
       o  2   030b686bedc4   2009-04-27 18:04 -0500   durin42
       |    Add gamma
       |
       o  1   c561b4e977df   2009-04-27 18:04 -0500   durin42

       |
       o  0   d8d2fcd0e319   2009-04-27 18:04 -0500   durin42
            Add alpha
       If you were to run hg histedit c561b4e977df, you would see the
       following file open in your editor:
       pick c561b4e977df Add beta
       pick 030b686bedc4 Add gamma
       pick 7c2fd3b9020c Add delta
       # Edit history between c561b4e977df and 7c2fd3b9020c
       #
       # Commands:
       #  p, pick = use commit
       #  e, edit = use commit, but stop for amending
       #  f, fold = use commit, but fold into previous commit (combines N and N-1)
       #  d, drop = remove commit from history
       #  m, mess = edit message without changing commit content
       #
       In this file, lines beginning with # are ignored. You must specify a
       rule for each revision in your history. For example, if you had meant
       to add gamma before beta, and then wanted to add delta in the same
       revision as beta, you would reorganize the file to look like this:
       pick 030b686bedc4 Add gamma
       pick c561b4e977df Add beta
       fold 7c2fd3b9020c Add delta
       # Edit history between c561b4e977df and 7c2fd3b9020c
       #
       # Commands:
       #  p, pick = use commit
       #  e, edit = use commit, but stop for amending
       #  f, fold = use commit, but fold into previous commit (combines N and N-1)
       #  d, drop = remove commit from history
       #  m, mess = edit message without changing commit content
       #
       At which point you close the editor and histedit starts working. When
       you specify a fold operation, histedit will open an editor when it
       folds those revisions together, offering you a chance to clean up the
       commit message:
       Add beta
       ***
       Add delta
       Edit the commit message to your liking, then close the editor. For
       this example, let's assume that the commit message was changed to Add
       beta and delta. After histedit has run and had a chance to remove any
       old or temporary revisions it needed, the history looks like this:
       @  2[tip]   989b4d060121   2009-04-27 18:04 -0500   durin42
       |    Add beta and delta.
       |
       o  1   081603921c3f   2009-04-27 18:04 -0500   durin42
       |    Add gamma
       |
       o  0   d8d2fcd0e319   2009-04-27 18:04 -0500   durin42
            Add alpha
       Note that histedit does not remove any revisions (even its own
       temporary ones) until after it has completed all the editing
       operations, so it will probably perform several strip operations when
       it's done. For the above example, it had to run strip twice. Strip
       can be slow depending on a variety of factors, so you might need to
       be a little patient. You can choose to keep the original revisions by
       passing the --keep flag.
       The edit operation will drop you back to a command prompt, allowing
       you to edit files freely, or even use hg record to commit some
       changes as a separate commit. When you're done, any remaining
       uncommitted changes will be committed as well. When done, run hg
       histedit --continue to finish this step. You'll be prompted for a new
       commit message, but the default commit message will be the original
       message for the edit ed revision.
       The message operation will give you a chance to revise a commit
       message without changing the contents. It's a shortcut for doing edit
       immediately followed by hg histedit --continue`.
       If histedit encounters a conflict when moving a revision (while
       handling pick or fold), it'll stop in a similar manner to edit with
       the difference that it won't prompt you for a commit message when
       done. If you decide at this point that you don't like how much work
       it will be to rearrange history, or that you made a mistake, you can
       use hg histedit --abort to abandon the new changes you have made and
       return to the state before you attempted to edit your history.
       If we clone the histedit-ed example repository above and add four
       more changes, such that we have the following history:

       If you run hg histedit --outgoing on the clone then it is the same as
       running hg histedit 836302820282. If you need plan to push to a
       repository that Mercurial does not detect to be related to the source
       repo, you can add a --force option.

       Keywords are only expanded in local repositories and not stored in
       the change history. The mechanism can be regarded as a convenience
       for the current user or for archive distribution.
       Keywords expand to the changeset data pertaining to the latest change
       relative to the working directory parent of each file.
       Configuration is done in the [keyword], [keywordset] and
       [keywordmaps] sections of hgrc files.
       Example:
       [keyword]
       # expand keywords in every python file except those matching "x*"
       **.py =
       x*    = ignore
       [keywordset]
       # prefer svn- over cvs-like default keywordmaps
       svn = True
       Note   The more specific you are in your filename patterns the less
              you lose speed in huge repositories.
       For [keywordmaps] template mapping and expansion demonstration and
       control run hg kwdemo. See hg help templates for a list of available
       templates and filters.
       Three additional date template filters are provided:
       utcdate
              "2006/09/18 15:13:13"
       svnutcdate
              "2006-09-18 15:13:13Z"
       svnisodate
              "2006-09-18 08:13:13 -700 (Mon, 18 Sep 2006)"
       The default template mappings (view with hg kwdemo -d) can be
       replaced with customized keywords and templates. Again, run hg kwdemo
       to control the results of your configuration changes.
       Before changing/disabling active keywords, you must run hg kwshrink
       to avoid storing expanded keywords in the change history.
       To force expansion after enabling it, or a configuration change, run
       hg kwexpand.
       Expansions spanning more than one line and incremental expansions,
       like CVS' $Log$, are not supported. A keyword template map "Log =
       {desc}" expands to the first line of the changeset description.
   Commands
   kwdemo
       hg kwdemo [-d] [-f RCFILE] [TEMPLATEMAP]...
       Show current, custom, or default keyword template maps and their
       expansions.
       Extend the current configuration by specifying maps as arguments and
       using -f/--rcfile to source an external hgrc file.
       Use -d/--default to disable current configuration.
       See hg help templates for information on templates and filters.
       Options:
       -d, --default
              show default keyword template maps
       -f, --rcfile
              read maps from rcfile
   kwexpand
       hg kwexpand [OPTION]... [FILE]...
       Run after (re)enabling keyword expansion.
       kwexpand refuses to run if given files contain local changes.
       Options:
       -I, --include
              include names matching the given patterns
       -X, --exclude
              exclude names matching the given patterns
   kwfiles
       hg kwfiles [OPTION]... [FILE]...
       List which files in the working directory are matched by the
       [keyword] configuration patterns.
       Useful to prevent inadvertent keyword expansion and to speed up
       execution by including only files that are actual candidates for
       expansion.
       See hg help keyword on how to construct patterns both for inclusion
       and exclusion of files.
       With -A/--all and -v/--verbose the codes used to show the status of
       files are:
       K = keyword expansion candidate
       k = keyword expansion candidate (not tracked)
       I = ignored
       i = ignored (not tracked)
       Options:
       -A, --all
              show keyword status flags of all files
       -i, --ignore
              show files excluded from expansion
       -u, --unknown
              only show unknown (not tracked) files
       -I, --include
              include names matching the given patterns
       -X, --exclude
              exclude names matching the given patterns
   kwshrink
       hg kwshrink [OPTION]... [FILE]...
       Must be run before changing/disabling active keywords.
       kwshrink refuses to run if given files contain local changes.
       Options:
       -I, --include
              include names matching the given patterns
       -X, --exclude
              exclude names matching the given patterns
   largefiles
       track large binary files
       Large binary files tend to be not very compressible, not very
       diffable, and not at all mergeable. Such files are not handled
       efficiently by Mercurial's storage format (revlog), which is based on
       compressed binary deltas; storing large binary files as regular
       Mercurial files wastes bandwidth and disk space and increases
       Mercurial's memory usage. The largefiles extension addresses these
       problems by adding a centralized client-server layer on top of
       Mercurial: largefiles live in a central store out on the network
       somewhere, and you only fetch the revisions that you need when you
       need them.
       largefiles works by maintaining a "standin file" in .hglf/ for each
       largefile. The standins are small (41 bytes: an SHA-1 hash plus
       newline) and are tracked by Mercurial. Largefile revisions are
       identified by the SHA-1 hash of their contents, which is written to
       the standin. largefiles uses that revision ID to get/put largefile
       revisions from/to the central store. This saves both disk space and
       bandwidth, since you don't need to retrieve all historical revisions
       of large files when you clone or pull.
       To start a new repository or add new large binary files, just add
       --large to your hg add command. For example:
       $ dd if=/dev/urandom of=randomdata count=2000
       $ hg add --large randomdata
       $ hg commit -m 'add randomdata as a largefile'
       When you push a changeset that adds/modifies largefiles to a remote
       repository, its largefile revisions will be uploaded along with it.
       Note that the remote Mercurial must also have the largefiles
       extension enabled for this to work.
       When you pull a changeset that affects largefiles from a remote
       repository, the largefiles for the changeset will by default not be
       pulled down. However, when you update to such a revision, any
       largefiles needed by that revision are downloaded and cached (if they
       have never been downloaded before). One way to pull largefiles when
       pulling is thus to use --update, which will update your working copy
       to the latest pulled revision (and thereby downloading any new
       largefiles).
       If you want to pull largefiles you don't need for update yet, then
       you can use pull with the --lfrev option or the hg lfpull command.
       If you know you are pulling from a non-default location and want to
       download all the largefiles that correspond to the new changesets at
       the same time, then you can pull with --lfrev "pulled()".
       If you just want to ensure that you will have the largefiles needed
       to merge or rebase with new heads that you are pulling, then you can
       pull with --lfrev "head(pulled())" flag to pre-emptively download any
       largefiles that are new in the heads you are pulling.
       Keep in mind that network access may now be required to update to
       changesets that you have not previously updated to. The nature of the
       largefiles extension means that updating is no longer guaranteed to
       be a local-only operation.
       If you already have large files tracked by Mercurial without the
       largefiles extension, you will need to convert your repository in
       order to benefit from largefiles. This is done with the hg lfconvert
       command:
       $ hg lfconvert --size 10 oldrepo newrepo
       In repositories that already have largefiles in them, any new file
       over 10MB will automatically be added as a largefile. To change this
       threshold, set largefiles.minsize in your Mercurial config file to
       the minimum size in megabytes to track as a largefile, or use the
       --lfsize option to the add command (also in megabytes):
       [largefiles]
       minsize = 2
       $ hg add --lfsize 2
       The largefiles.patterns config option allows you to specify a list of
       filename patterns (see hg help patterns) that should always be
       tracked as largefiles:
       [largefiles]
       patterns =
         *.jpg
         re:.*\.(png|bmp)$
         library.zip
         content/audio/*
       Files that match one of these patterns will be added as largefiles
       regardless of their size.
       The largefiles.minsize and largefiles.patterns config options will be
       ignored for any repositories not already containing a largefile. To
       add the first largefile to a repository, you must explicitly do so
       with the --large flag passed to the hg add command.
   Commands
   lfconvert
       hg lfconvert SOURCE DEST [FILE ...]
       Convert repository SOURCE to a new repository DEST, identical to
       SOURCE except that certain files will be converted as largefiles:
       specifically, any file that matches any PATTERN or whose size is
       above the minimum size threshold is converted as a largefile. The
       size used to determine whether or not to track a file as a largefile
       is the size of the first version of the file. The minimum size can be
       specified either with --size or in configuration as largefiles.size.
       After running this command you will need to make sure that largefiles
       is enabled anywhere you intend to push the new repository.
       Use --to-normal to convert largefiles back to normal files; after
       this, the DEST repository can be used without largefiles at all.
       Options:
       -s, --size
              minimum size (MB) for files to be converted as largefiles
       --to-normal
              convert from a largefiles repo to a normal repo
   lfpull
       hg lfpull -r REV... [-e CMD] [--remotecmd CMD] [SOURCE]
       Pull largefiles that are referenced from local changesets but missing
       locally, pulling from a remote repository to the local cache.
       If SOURCE is omitted, the 'default' path will be used.  See hg help
       urls for more information.
       Some examples:
       · pull largefiles for all branch heads:
         hg lfpull -r "head() and not closed()"
       · pull largefiles on the default branch:
         hg lfpull -r "branch(default)"
       Options:
       -r, --rev
              pull largefiles for these revisions
       -e, --ssh
              specify ssh command to use
       --remotecmd
              specify hg command to run on the remote side
       --insecure
              do not verify server certificate (ignoring web.cacerts config)
   mq
       manage a stack of patches
       This extension lets you work with a stack of patches in a Mercurial
       repository. It manages two stacks of patches - all known patches, and
       applied patches (subset of known patches).
       Known patches are represented as patch files in the .hg/patches
       directory. Applied patches are both patch files and changesets.
       Common tasks (use hg help command for more details):
       create new patch                          qnew
       import existing patch                     qimport
       print patch series                        qseries
       print applied patches                     qapplied
       add known patch to applied stack          qpush
       remove patch from applied stack           qpop
       refresh contents of top applied patch     qrefresh
       By default, mq will automatically use git patches when required to
       avoid losing file mode changes, copy records, binary files or empty
       files creations or deletions. This behaviour can be configured with:
       [mq]
       git = auto/keep/yes/no
       If set to 'keep', mq will obey the [diff] section configuration while
       preserving existing git patches upon qrefresh. If set to 'yes' or
       'no', mq will override the [diff] section and always generate git or
       regular patches, possibly losing data in the second case.
       It may be desirable for mq changesets to be kept in the secret phase
       (see hg help phases), which can be enabled with the following
       setting:
       [mq]
       secret = True
       You will by default be managing a patch queue named "patches". You
       can create other, independent patch queues with the hg qqueue
       command.
       If the working directory contains uncommitted files, qpush, qpop and
       qgoto abort immediately. If -f/--force is used, the changes are
       discarded. Setting:
       [mq]
       keepchanges = True
       make them behave as if --keep-changes were passed, and
       non-conflicting local changes will be tolerated and preserved. If
       incompatible options such as -f/--force or --exact are passed, this
       setting is ignored.
   Commands
   qapplied
       hg qapplied [-1] [-s] [PATCH]
       Returns 0 on success.
       Options:
       -1, --last
              show only the preceding applied patch
       -s, --summary
              print first line of patch header
   qclone
       hg qclone [OPTION]... SOURCE [DEST]
       If source is local, destination will have no patches applied. If
       source is remote, this command can not check if patches are applied
       in source, so cannot guarantee that patches are not applied in
       destination. If you clone remote repository, be sure before that it
       has no patches applied.
       Source patch repository is looked for in <src>/.hg/patches by
       default. Use -p <url> to change.
       The patch directory must be a nested Mercurial repository, as would
       be created by hg init --mq.
       Return 0 on success.
       Options:
       --pull use pull protocol to copy metadata
       -U, --noupdate
              do not update the new working directories
       --uncompressed
              use uncompressed transfer (fast over LAN)
       -p, --patches
              location of source patch repository
       -e, --ssh
              specify ssh command to use
       --remotecmd
              specify hg command to run on the remote side
       --insecure
              do not verify server certificate (ignoring web.cacerts config)
   qcommit
       hg qcommit [OPTION]... [FILE]...
       This command is deprecated; use hg commit --mq instead.

       -A, --addremove
              mark new/missing files as added/removed before committing
       --close-branch
              mark a branch as closed, hiding it from the branch list
       --amend
              amend the parent of the working dir

              record the specified user as committer
       -S, --subrepos
              recurse into subrepositories
              aliases: qci
   qdelete
       hg qdelete [-k] [PATCH]...
       The patches must not be applied, and at least one patch is required.
       Exact patch identifiers must be given. With -k/--keep, the patch
       files are preserved in the patch directory.
       To stop managing a patch and move it into permanent history, use the
       hg qfinish command.
       Options:
       -k, --keep
              keep patch file
       -r, --rev
              stop managing a revision (DEPRECATED)
              aliases: qremove qrm
   qdiff
       hg qdiff [OPTION]... [FILE]...
       Shows a diff which includes the current patch as well as any changes
       which have been made in the working directory since the last refresh
       (thus showing what the current patch would become after a qrefresh).
       Use hg diff if you only want to see the changes made since the last
       qrefresh, or hg export qtip if you want to see changes made by the
       current patch without including changes made since the qrefresh.
       Returns 0 on success.
       Options:
       -a, --text
              treat all files as text
       -g, --git
              use git extended diff format

              show which function each change is in
       --reverse
              produce a diff that undoes the changes
       -w, --ignore-all-space
              ignore white space when comparing lines
       -b, --ignore-space-change
              ignore changes in the amount of white space
       -B, --ignore-blank-lines
              ignore changes whose lines are all blank
       -U, --unified
              number of lines of context to show
       --stat output diffstat-style summary of changes
       -I, --include
              include names matching the given patterns
       -X, --exclude
              exclude names matching the given patterns
   qfinish
       hg qfinish [-a] [REV]...
       Finishes the specified revisions (corresponding to applied patches)
       by moving them out of mq control into regular repository history.
       Accepts a revision range or the -a/--applied option. If --applied is
       specified, all applied mq revisions are removed from mq control.
       Otherwise, the given revisions must be at the base of the stack of
       applied patches.
       This can be especially useful if your changes have been applied to an
       upstream repository, or if you are about to push your changes to
       upstream.
       Returns 0 on success.
       Options:
       -a, --applied
              finish all applied changesets
   qfold
       hg qfold [-e] [-k] [-m TEXT] [-l FILE] PATCH...
       Patches must not yet be applied. Each patch will be successively
       applied to the current patch in the order given. If all the patches
       apply successfully, the current patch will be refreshed with the new
       cumulative patch, and the folded patches will be deleted. With
       -k/--keep, the folded patch files will not be removed afterwards.
       The header for each folded patch will be concatenated with the
       current patch header, separated by a line of * * *.
       Returns 0 on success.
       Options:
       -e, --edit
              edit patch header
       -k, --keep
              keep folded patch files
       -m, --message
              use text as commit message
       -l, --logfile
              read commit message from file
   qgoto
       hg qgoto [OPTION]... PATCH
       Returns 0 on success.
       Options:
       --keep-changes
              tolerate non-conflicting local changes
       -f, --force
              overwrite any local changes
       --no-backup
              do not save backup copies of files
   qguard
       hg qguard [-l] [-n] [PATCH] [-- [+GUARD]... [-GUARD]...]
       Guards control whether a patch can be pushed. A patch with no guards
       is always pushed. A patch with a positive guard ("+foo") is pushed
       only if the hg qselect command has activated it. A patch with a
       negative guard ("-foo") is never pushed if the hg qselect command has
       activated it.
       With no arguments, print the currently active guards.  With
       arguments, set guards for the named patch.
       Note   Specifying negative guards now requires '--'.
       To set guards on another patch:
       hg qguard other.patch -- +2.6.17 -stable
       Returns 0 on success.
       Options:
       -l, --list
              list all patches and guards
       -n, --none
              drop all guards
   qheader
       hg qheader [PATCH]
       Returns 0 on success.
   qimport
       hg qimport [-e] [-n NAME] [-f] [-g] [-P] [-r REV]... [FILE]...
       The patch is inserted into the series after the last applied patch.
       If no patches have been applied, qimport prepends the patch to the
       series.
       The patch will have the same name as its source file unless you give
       it a new one with -n/--name.
       You can register an existing patch inside the patch directory with
       the -e/--existing flag.
       With -f/--force, an existing patch of the same name will be
       overwritten.
       An existing changeset may be placed under mq control with -r/--rev
       (e.g. qimport --rev tip -n patch will place tip under mq control).
       With -g/--git, patches imported with --rev will use the git diff
       format. See the diffs help topic for information on why this is
       important for preserving rename/copy information and permission
       changes. Use hg qfinish to remove changesets from mq control.
       To import a patch from standard input, pass - as the patch file.
       When importing from standard input, a patch name must be specified
       using the --name flag.
       To import an existing patch while renaming it:
       hg qimport -e existing-patch -n new-name
       Returns 0 if import succeeded.
       Options:
       -e, --existing
              import file in patch directory
       -n, --name
              name of patch file
       -f, --force
              overwrite existing files
       -r, --rev
              place existing revisions under mq control
       -g, --git
              use git extended diff format
       -P, --push
              qpush after importing
   qinit
       hg qinit [-c]
       The queue repository is unversioned by default. If -c/--create-repo
       is specified, qinit will create a separate nested repository for
       patches (qinit -c may also be run later to convert an unversioned
       patch repository into a versioned one). You can use qcommit to commit
       changes to this queue repository.
       This command is deprecated. Without -c, it's implied by other
       relevant commands. With -c, use hg init --mq instead.
       Options:
       -c, --create-repo
              create queue repository
   qnew
       hg qnew [-e] [-m TEXT] [-l FILE] PATCH [FILE]...
       qnew creates a new patch on top of the currently-applied patch (if
       any). The patch will be initialized with any outstanding changes in
       the working directory. You may also use -I/--include, -X/--exclude,
       and/or a list of files after the patch name to add only changes to
       matching files to the new patch, leaving the rest as uncommitted
       modifications.
       -u/--user and -d/--date can be used to set the (given) user and date,
       respectively. -U/--currentuser and -D/--currentdate set user to
       current user and date to current date.
       -e/--edit, -m/--message or -l/--logfile set the patch header as well
       as the commit message. If none is specified, the header is empty and
       the commit message is '[mq]: PATCH'.
       Use the -g/--git option to keep the patch in the git extended diff
       format. Read the diffs help topic for more information on why this is
       important for preserving permission changes and copy/rename
       information.
       Returns 0 on successful creation of a new patch.
       Options:
       -e, --edit
              edit commit message
       -f, --force
              import uncommitted changes (DEPRECATED)
       -g, --git
              use git extended diff format
       -U, --currentuser
              add "From: <current user>" to patch
       -u, --user
              add "From: <USER>" to patch
       -D, --currentdate
              add "Date: <current date>" to patch
       -d, --date
              add "Date: <DATE>" to patch
       -I, --include
              include names matching the given patterns
       -X, --exclude
              exclude names matching the given patterns
       -m, --message
              use text as commit message
       -l, --logfile
              read commit message from file
   qnext
       hg qnext [-s]
       Returns 0 on success.
       Options:
       -s, --summary
              print first line of patch header
   qpop
       hg qpop [-a] [-f] [PATCH | INDEX]
       Without argument, pops off the top of the patch stack. If given a
       patch name, keeps popping off patches until the named patch is at the
       top of the stack.
       By default, abort if the working directory contains uncommitted
       changes. With --keep-changes, abort only if the uncommitted files
       overlap with patched files. With -f/--force, backup and discard
       changes made to such files.
       Return 0 on success.
       Options:
       -a, --all
              pop all patches
       -n, --name
              queue name to pop (DEPRECATED)

              forget any local changes to patched files
       --no-backup
              do not save backup copies of files
   qprev
       hg qprev [-s]
       Returns 0 on success.
       Options:
       -s, --summary
              print first line of patch header
   qpush
       hg qpush [-f] [-l] [-a] [--move] [PATCH | INDEX]
       By default, abort if the working directory contains uncommitted
       changes. With --keep-changes, abort only if the uncommitted files
       overlap with patched files. With -f/--force, backup and patch over
       uncommitted changes.
       Return 0 on success.
       Options:
       --keep-changes
              tolerate non-conflicting local changes
       -f, --force
              apply on top of local changes
       -e, --exact
              apply the target patch to its recorded parent
       -l, --list
              list patch name in commit text
       -a, --all
              apply all patches
       -m, --merge
              merge from another queue (DEPRECATED)
       -n, --name
              merge queue name (DEPRECATED)
       --move reorder patch series and apply only the patch
       --no-backup
              do not save backup copies of files
   qqueue
       hg qqueue [OPTION] [QUEUE]
       Supports switching between different patch queues, as well as
       creating new patch queues and deleting existing ones.
       Omitting a queue name or specifying -l/--list will show you the
       registered queues - by default the "normal" patches queue is
       registered. The currently active queue will be marked with
       "(active)". Specifying --active will print only the name of the
       active queue.
       To create a new queue, use -c/--create. The queue is automatically
       made active, except in the case where there are applied patches from
       the currently active queue in the repository. Then the queue will
       only be created and switching will fail.
       To delete an existing queue, use --delete. You cannot delete the
       currently active queue.
       Returns 0 on success.
       Options:
       -l, --list
              list all available queues
       --active
              print name of active queue
       -c, --create
              create new queue
       --rename
              rename active queue
       --delete
              delete reference to queue
       --purge
              delete queue, and remove patch dir
   qrefresh
       hg qrefresh [-I] [-X] [-e] [-m TEXT] [-l FILE] [-s] [FILE]...
       If any file patterns are provided, the refreshed patch will contain
       only the modifications that match those patterns; the remaining
       modifications will remain in the working directory.
       If -s/--short is specified, files currently included in the patch
       will be refreshed just like matched files and remain in the patch.
       If -e/--edit is specified, Mercurial will start your configured
       editor for you to enter a message. In case qrefresh fails, you will
       find a backup of your message in .hg/last-message.txt.
       hg add/remove/copy/rename work as usual, though you might want to use
       git-style patches (-g/--git or [diff] git=1) to track copies and
       renames. See the diffs help topic for more information on the git
       diff format.
       Returns 0 on success.
       Options:
       -e, --edit
              edit commit message
       -g, --git
              use git extended diff format
       -s, --short
              refresh only files already in the patch and specified files
       -U, --currentuser
              add/update author field in patch with current user
       -u, --user
              add/update author field in patch with given user
       -D, --currentdate
              add/update date field in patch with current date
       -d, --date
              add/update date field in patch with given date
       -I, --include
              include names matching the given patterns
       -X, --exclude
              exclude names matching the given patterns
       -m, --message
              use text as commit message
       -l, --logfile
              read commit message from file
   qrename
       hg qrename PATCH1 [PATCH2]
       With one argument, renames the current patch to PATCH1.  With two
       arguments, renames PATCH1 to PATCH2.
       Returns 0 on success.
          aliases: qmv
   qrestore
       hg qrestore [-d] [-u] REV
       This command is deprecated, use hg rebase instead.
       Options:
       -d, --delete
              delete save entry
       -u, --update
              update queue working directory
   qsave
       hg qsave [-m TEXT] [-l FILE] [-c] [-n NAME] [-e] [-f]
       This command is deprecated, use hg rebase instead.
       Options:
       -c, --copy
              copy patch directory
       -n, --name
              copy directory name
       -e, --empty
              clear queue status file
       -f, --force
              force copy
       -m, --message
              use text as commit message
       -l, --logfile
              read commit message from file
   qselect
       hg qselect [OPTION]... [GUARD]...
       Use the hg qguard command to set or print guards on patch, then use
       qselect to tell mq which guards to use. A patch will be pushed if it
       has no guards or any positive guards match the currently selected
       guard, but will not be pushed if any negative guards match the
       current guard. For example:
       qguard foo.patch -- -stable    (negative guard)
       qguard bar.patch    +stable    (positive guard)
       qselect stable
       This activates the "stable" guard. mq will skip foo.patch (because it
       has a negative match) but push bar.patch (because it has a positive
       match).
       With no arguments, prints the currently active guards.  With one
       argument, sets the active guard.
       Use -n/--none to deactivate guards (no other arguments needed).  When
       no guards are active, patches with positive guards are skipped and
       patches with negative guards are pushed.
       qselect can change the guards on applied patches. It does not pop
       guarded patches by default. Use --pop to pop back to the last applied
       patch that is not guarded. Use --reapply (which implies --pop) to
       push back to the current patch afterwards, but skip guarded patches.
       Use -s/--series to print a list of all guards in the series file (no
       other arguments needed). Use -v for more information.
       Returns 0 on success.
       Options:
       -n, --none
              disable all guards
       -s, --series
              list all guards in series file
       --pop  pop to before first guarded applied patch
       --reapply
              pop, then reapply patches
   qseries
       hg qseries [-ms]
       Returns 0 on success.
       Options:
       -m, --missing
              print patches not in series
       -s, --summary
              print first line of patch header
   qtop
       hg qtop [-s]
       Returns 0 on success.
       Options:
       -s, --summary
              print first line of patch header
   qunapplied
       hg qunapplied [-1] [-s] [PATCH]
       Returns 0 on success.
       Options:
       -1, --first
              show only the first patch
       -s, --summary
              print first line of patch header
   strip
       hg strip [-k] [-f] [-n] [-B bookmark] [-r] REV...
       The strip command removes the specified changesets and all their
       descendants. If the working directory has uncommitted changes, the
       operation is aborted unless the --force flag is supplied, in which
       case changes will be discarded.
       If a parent of the working directory is stripped, then the working
       directory will automatically be updated to the most recent available
       ancestor of the stripped parent after the operation completes.
       Any stripped changesets are stored in .hg/strip-backup as a bundle
       (see hg help bundle and hg help unbundle). They can be restored by
       running hg unbundle .hg/strip-backup/BUNDLE, where BUNDLE is the
       bundle file created by the strip. Note that the local revision
       numbers will in general be different after the restore.
       Use the --no-backup option to discard the backup bundle once the
       operation completes.
       Strip is not a history-rewriting operation and can be used on
       changesets in the public phase. But if the stripped changesets have
       been pushed to a remote repository you will likely pull them again.
       Return 0 on success.
       Options:
       -r, --rev
              strip specified revision (optional, can specify revisions
              without this option)
       -f, --force
              force removal of changesets, discard uncommitted changes (no
              backup)
       -b, --backup
              bundle only changesets with local revision number greater than
              REV which are not descendants of REV (DEPRECATED)
       --no-backup
              no backups
       --nobackup
              no backups (DEPRECATED)
       -n     ignored  (DEPRECATED)
       -k, --keep
              do not modify working copy during strip
       -B, --bookmark
              remove revs only reachable from given bookmark
   notify
       hooks for sending email push notifications
       This extension implements hooks to send email notifications when
       changesets are sent from or received by the local repository.
       First, enable the extension as explained in hg help extensions, and
       register the hook you want to run. incoming and changegroup hooks are
       run when changesets are received, while outgoing hooks are for
       changesets sent to another repository:
       [hooks]
       # one email for each incoming changeset
       incoming.notify = python:hgext.notify.hook
       # one email for all incoming changesets
       changegroup.notify = python:hgext.notify.hook
       # one email for all outgoing changesets
       outgoing.notify = python:hgext.notify.hook
       This registers the hooks. To enable notification, subscribers must be
       assigned to repositories. The [usersubs] section maps multiple
       repositories to a given recipient. The [reposubs] section maps
       multiple recipients to a single repository:
       [usersubs]
       # key is subscriber email, value is a comma-separated list of repo patterns
       user@host = pattern
       [reposubs]
       # key is repo pattern, value is a comma-separated list of subscriber emails
       pattern = user@host
       A pattern is a glob matching the absolute path to a repository,
       optionally combined with a revset expression. A revset expression, if
       present, is separated from the glob by a hash. Example:
       [reposubs]
       */widgets#branch(release) = qa-team@example.com
       This sends to qa-team@example.com whenever a changeset on the release
       branch triggers a notification in any repository ending in widgets.
       In order to place them under direct user management, [usersubs] and
       [reposubs] sections may be placed in a separate hgrc file and
       incorporated by reference:
       [notify]
       config = /path/to/subscriptionsfile
       Notifications will not be sent until the notify.test value is set to
       False; see below.
       Notifications content can be tweaked with the following configuration
       entries:
       notify.test
              If True, print messages to stdout instead of sending them.
              Default: True.
       notify.sources
              Space-separated list of change sources. Notifications are
              activated only when a changeset's source is in this list.
              Sources may be:
              serve
                     changesets received via http or ssh
              pull
                     changesets received via hg pull
              unbundle
                     changesets received via hg unbundle
              push
                     changesets sent or received via hg push
              bundle
                     changesets sent via hg unbundle
              Default: serve.
       notify.strip
              Number of leading slashes to strip from url paths. By default,
              notifications reference repositories with their absolute path.
              notify.strip lets you turn them into relative paths. For
              example, notify.strip=3 will change /long/path/repository into
              repository. Default: 0.
       notify.domain
              Default email domain for sender or recipients with no explicit
              domain.
       notify.style
              Style file to use when formatting emails.
       notify.template
              Template to use when formatting emails.
       notify.incoming
              Template to use when run as an incoming hook, overriding
              notify.template.
       notify.outgoing
              Template to use when run as an outgoing hook, overriding
              notify.template.
       notify.changegroup
              Template to use when running as a changegroup hook, overriding
              notify.template.
       notify.maxdiff
              Maximum number of diff lines to include in notification email.
              Set to 0 to disable the diff, or -1 to include all of it.
              Default: 300.
       notify.maxsubject
              Maximum number of characters in email's subject line. Default:
              67.
       notify.diffstat
              Set to True to include a diffstat before diff content.
              Default: True.
       notify.merge
              If True, send notifications for merge changesets. Default:
              True.
       notify.mbox
              If set, append mails to this mbox file instead of sending.
              Default: None.
       notify.fromauthor
              If set, use the committer of the first changeset in a
              changegroup for the "From" field of the notification mail. If
              not set, take the user from the pushing repo.  Default: False.
       If set, the following entries will also be used to customize the
       notifications:
       email.from
              Email From address to use if none can be found in the
              generated email content.
       web.baseurl
              Root repository URL to combine with repository paths when
              making references. See also notify.strip.
   pager
       browse command output with an external pager
       To set the pager that should be used, set the application variable:
       [pager]
       pager = less -FRX
       If no pager is set, the pager extensions uses the environment
       variable $PAGER. If neither pager.pager, nor $PAGER is set, no pager
       is used.
       You can disable the pager for certain commands by adding them to the
       pager.ignore list:
       [pager]
       ignore = version, help, update
       You can also enable the pager only for certain commands using
       pager.attend. Below is the default list of commands to be paged:
       [pager]
       attend = annotate, cat, diff, export, glog, log, qdiff
       Setting pager.attend to an empty value will cause all commands to be
       paged.
       If pager.attend is present, pager.ignore will be ignored.
       To ignore global commands like hg version or hg help, you have to
       specify them in your user configuration file.
       The --pager=... option can also be used to control when the pager is
       used. Use a boolean value like yes, no, on, off, or use auto for
       normal behavior.
   patchbomb
       command to send changesets as (a series of) patch emails
       The series is started off with a "[PATCH 0 of N]" introduction, which
       describes the series as a whole.
       Each patch email has a Subject line of "[PATCH M of N] ...", using
       the first line of the changeset description as the subject text. The
       message contains two or three body parts:
       · The changeset description.
       · [Optional] The result of running diffstat on the patch.
       · The patch itself, as generated by hg export.
       Each message refers to the first in the series using the In-Reply-To
       and References headers, so they will show up as a sequence in
       threaded mail and news readers, and in mail archives.
       To configure other defaults, add a section like this to your
       configuration file:
       [email]
       from = My Name <my@email>
       to = recipient1, recipient2, ...
       cc = cc1, cc2, ...
       bcc = bcc1, bcc2, ...
       reply-to = address1, address2, ...
       Use [patchbomb] as configuration section name if you need to override
       global [email] address settings.
       Then you can use the hg email command to mail a series of changesets
       as a patchbomb.
       You can also either configure the method option in the email section
       to be a sendmail compatible mailer or fill out the [smtp] section so
       that the patchbomb extension can automatically send patchbombs
       directly from the commandline. See the [email] and [smtp] sections in
       hgrc(5) for details.
   Commands
   email
       hg email [OPTION]... [DEST]...
       By default, diffs are sent in the format generated by hg export, one
       per message. The series starts with a "[PATCH 0 of N]" introduction,
       which describes the series as a whole.
       Each patch email has a Subject line of "[PATCH M of N] ...", using
       the first line of the changeset description as the subject text.  The
       message contains two or three parts. First, the changeset
       description.
       With the -d/--diffstat option, if the diffstat program is installed,
       the result of running diffstat on the patch is inserted.
       Finally, the patch itself, as generated by hg export.
       With the -d/--diffstat or --confirm options, you will be presented
       with a final summary of all messages and asked for confirmation
       before the messages are sent.
       By default the patch is included as text in the email body for easy
       reviewing. Using the -a/--attach option will instead create an
       attachment for the patch. With -i/--inline an inline attachment will
       be created. You can include a patch both as text in the email body
       and as a regular or an inline attachment by combining the -a/--attach
       or -i/--inline with the --body option.
       With -o/--outgoing, emails will be generated for patches not found in
       the destination repository (or only those which are ancestors of the
       specified revisions if any are provided)
       With -b/--bundle, changesets are selected as for --outgoing, but a
       single email containing a binary Mercurial bundle as an attachment
       will be sent.
       With -m/--mbox, instead of previewing each patchbomb message in a
       pager or sending the messages directly, it will create a UNIX mailbox
       file with the patch emails. This mailbox file can be previewed with
       any mail user agent which supports UNIX mbox files.
       With -n/--test, all steps will run, but mail will not be sent.  You
       will be prompted for an email recipient address, a subject and an
       introductory message describing the patches of your patchbomb.  Then
       when all is done, patchbomb messages are displayed. If the PAGER
       environment variable is set, your pager will be fired up once for
       each patchbomb message, so you can verify everything is alright.
       In case email sending fails, you will find a backup of your series
       introductory message in .hg/last-email.txt.
       Examples:
       hg email -r 3000          # send patch 3000 only
       hg email -r 3000 -r 3001  # send patches 3000 and 3001
       hg email -r 3000:3005     # send patches 3000 through 3005
       hg email 3000             # send patch 3000 (deprecated)
       hg email -o               # send all patches not in default
       hg email -o DEST          # send all patches not in DEST
       hg email -o -r 3000       # send all ancestors of 3000 not in default
       hg email -o -r 3000 DEST  # send all ancestors of 3000 not in DEST
       hg email -b               # send bundle of all patches not in default
       hg email -b DEST          # send bundle of all patches not in DEST
       hg email -b -r 3000       # bundle of all ancestors of 3000 not in default
       hg email -b -r 3000 DEST  # bundle of all ancestors of 3000 not in DEST
       hg email -o -m mbox &&    # generate an mbox file...
         mutt -R -f mbox         # ... and view it with mutt
       hg email -o -m mbox &&    # generate an mbox file ...
         formail -s sendmail \   # ... and use formail to send from the mbox
           -bm -t < mbox         # ... using sendmail
       Before using this command, you will need to enable email in your
       hgrc. See the [email] section in hgrc(5) for details.

   progress
       show progress bars for some actions
       This extension uses the progress information logged by hg commands to
       draw progress bars that are as informative as possible. Some progress
       bars only offer indeterminate information, while others have a
       definite end point.
       The following settings are available:
       [progress]
       delay = 3 # number of seconds (float) before showing the progress bar
       changedelay = 1 # changedelay: minimum delay before showing a new topic.
                       # If set to less than 3 * refresh, that value will
                       # be used instead.
       refresh = 0.1 # time in seconds between refreshes of the progress bar
       format = topic bar number estimate # format of the progress bar
       width = <none> # if set, the maximum width of the progress information
                      # (that is, min(width, term width) will be used)
       clear-complete = True # clear the progress bar after it's done
       disable = False # if true, don't show a progress bar
       assume-tty = False # if true, ALWAYS show a progress bar, unless
                          # disable is given
       Valid entries for the format field are topic, bar, number, unit,
       estimate, speed, and item. item defaults to the last 20 characters of
       the item, but this can be changed by adding either -<num> which would
       take the last num characters, or +<num> for the first num characters.
   purge
       command to delete untracked files from the working directory
   Commands
   purge
       hg purge [OPTION]... [DIR]...
       Delete files not known to Mercurial. This is useful to test local and
       uncommitted changes in an otherwise-clean source tree.
       This means that purge will delete:
       · Unknown files: files marked with "?" by hg status
       · Empty directories: in fact Mercurial ignores directories unless
         they contain files under source control management
       But it will leave untouched:
       · Modified and unmodified tracked files
       · Ignored files (unless --all is specified)
       · New files added to the repository (with hg add)
       If directories are given on the command line, only files in these
       directories are considered.
       Be careful with purge, as you could irreversibly delete some files
       you forgot to add to the repository. If you only want to print the
       list of files that this program would delete, use the --print option.
       Options:
       -a, --abort-on-err
              abort if an error occurs
       --all  purge ignored files too
       -p, --print
              print filenames instead of deleting them
       -0, --print0
              end filenames with NUL, for use with xargs (implies
              -p/--print)
       -I, --include
              include names matching the given patterns
       -X, --exclude
              exclude names matching the given patterns
              aliases: clean
   rebase
       command to move sets of revisions to a different ancestor
       This extension lets you rebase changesets in an existing Mercurial
       repository.
       For more information:
       http://mercurial.selenic.com/wiki/RebaseExtension
   Commands
   rebase
       hg rebase [-s REV | -b REV] [-d REV] [OPTION]
       Rebase uses repeated merging to graft changesets from one part of
       history (the source) onto another (the destination). This can be
       useful for linearizing local changes relative to a master development
       tree.
       You should not rebase changesets that have already been shared with
       others. Doing so will force everybody else to perform the same rebase
       or they will end up with duplicated changesets after pulling in your
       rebased changesets.
       In its default configuration, Mercurial will prevent you from
       rebasing published changes. See hg help phases for details.
       If you don't specify a destination changeset (-d/--dest), rebase uses
       the tipmost head of the current named branch as the destination. (The
       destination changeset is not modified by rebasing, but new changesets
       are added as its descendants.)
       You can specify which changesets to rebase in two ways: as a "source"
       changeset or as a "base" changeset. Both are shorthand for a
       topologically related set of changesets (the "source branch"). If you
       specify source (-s/--source), rebase will rebase that changeset and
       all of its descendants onto dest. If you specify base (-b/--base),
       rebase will select ancestors of base back to but not including the
       common ancestor with dest. Thus, -b is less precise but more
       convenient than -s: you can specify any changeset in the source
       branch, and rebase will select the whole branch. If you specify
       neither -s nor -b, rebase uses the parent of the working directory as
       the base.
       For advanced usage, a third way is available through the --rev
       option. It allows you to specify an arbitrary set of changesets to
       rebase. Descendants of revs you specify with this option are not
       automatically included in the rebase.
       By default, rebase recreates the changesets in the source branch as
       descendants of dest and then destroys the originals. Use --keep to
       preserve the original source changesets. Some changesets in the
       source branch (e.g. merges from the destination branch) may be
       dropped if they no longer contribute any change.
       One result of the rules for selecting the destination changeset and
       source branch is that, unlike merge, rebase will do nothing if you
       are at the latest (tipmost) head of a named branch with two heads.
       You need to explicitly specify source and/or destination (or update
       to the other head, if it's the head of the intended source branch).
       If a rebase is interrupted to manually resolve a merge, it can be
       continued with --continue/-c or aborted with --abort/-a.
       Returns 0 on success, 1 if nothing to rebase.
       Options:
       -s, --source
              rebase from the specified changeset
       -b, --base
              rebase from the base of the specified changeset (up to
              greatest common ancestor of base and dest)
       -r, --rev
              rebase these revisions
       -d, --dest
              rebase onto the specified changeset
       --collapse
              collapse the rebased changesets
       -m, --message
              use text as collapse commit message
       -e, --edit
              invoke editor on commit messages
       -l, --logfile
              read collapse commit message from file
       --keep keep original changesets
       --keepbranches
              keep original branch names
       -D, --detach
              (DEPRECATED)
       -t, --tool
              specify merge tool
       -c, --continue
              continue an interrupted rebase
       -a, --abort
              abort an interrupted rebase
       --style
              display using template map file
       --template
              display with template
   record
       commands to interactively select changes for commit/qrefresh
   Commands
   qrecord
       hg qrecord [OPTION]... PATCH [FILE]...
       See hg help qnew & hg help record for more information and usage.
   record
       hg record [OPTION]... [FILE]...
       If a list of files is omitted, all changes reported by hg status will
       be candidates for recording.
       See hg help dates for a list of formats valid for -d/--date.
       You will be prompted for whether to record changes to each modified
       file, and for files with multiple changes, for each change to use.
       For each query, the following responses are possible:
       y - record this change
       n - skip this change
       e - edit this change manually
       s - skip remaining changes to this file
       f - record remaining changes to this file
       d - done, skip remaining changes and files
       a - record all changes to all remaining files
       q - quit, recording no changes
       ? - display help
       This command is not available when committing a merge.
       Options:
       -A, --addremove

              recurse into subrepositories
       -w, --ignore-all-space
              ignore white space when comparing lines
       -b, --ignore-space-change
              ignore changes in the amount of white space
       -B, --ignore-blank-lines
              ignore changes whose lines are all blank
   relink
       recreates hardlinks between repository clones
   Commands
   relink
       hg relink [ORIGIN]
       When repositories are cloned locally, their data files will be
       hardlinked so that they only use the space of a single repository.
       Unfortunately, subsequent pulls into either repository will break
       hardlinks for any files touched by the new changesets, even if both
       repositories end up pulling the same changes.
       Similarly, passing --rev to "hg clone" will fail to use any
       hardlinks, falling back to a complete copy of the source repository.
       This command lets you recreate those hardlinks and reclaim that
       wasted space.
       This repository will be relinked to share space with ORIGIN, which
       must be on the same local disk. If ORIGIN is omitted, looks for
       "default-relink", then "default", in [paths].
       Do not attempt any read operations on this repository while the
       command is running. (Both repositories will be locked against
       writes.)
   schemes
       extend schemes with shortcuts to repository swarms
       This extension allows you to specify shortcuts for parent URLs with a
       lot of repositories to act like a scheme, for example:
       [schemes]
       py = http://code.python.org/hg/
       After that you can use it like:
       hg clone py://trunk/
       Additionally there is support for some more complex schemas, for
       example used by Google Code:
       [schemes]
       gcode = http://{1}.googlecode.com/hg/
       The syntax is taken from Mercurial templates, and you have unlimited
       number of variables, starting with {1} and continuing with {2}, {3}
       and so on. This variables will receive parts of URL supplied, split
       by /. Anything not specified as {part} will be just appended to an
       URL.
       For convenience, the extension adds these schemes by default:
       [schemes]
       py = http://hg.python.org/
       bb = https://bitbucket.org/
       bb+ssh = ssh://hg@bitbucket.org/
       gcode = https://{1}.googlecode.com/hg/
       kiln = https://{1}.kilnhg.com/Repo/
       You can override a predefined scheme by defining a new scheme with
       the same name.
   share
       share a common history between several working directories
   Commands
   share
       hg share [-U] SOURCE [DEST]
       Initialize a new repository and working directory that shares its
       history with another repository.
       Note   using rollback or extensions that destroy/modify history (mq,
              rebase, etc.) can cause considerable confusion with shared
              clones. In particular, if two shared clones are both updated
              to the same changeset, and one of them destroys that changeset
              with rollback, the other clone will suddenly stop working: all
              operations will fail with "abort: working directory has
              unknown parent". The only known workaround is to use
              debugsetparents on the broken clone to reset it to a changeset
              that still exists (e.g. tip).
       Options:
       -U, --noupdate
              do not create a working copy
   unshare
       hg unshare
       Copy the store data to the repo and remove the sharedpath data.
   transplant
       command to transplant changesets from another branch
       This extension allows you to transplant changes to another parent
       revision, possibly in another repository. The transplant is done
       using 'diff' patches.
       Transplanted patches are recorded in .hg/transplant/transplants, as a
       map from a changeset hash to its hash in the source repository.
   Commands
   transplant
       hg transplant [-s REPO] [-b BRANCH [-a]] [-p REV] [-m REV] [REV]...
       Selected changesets will be applied on top of the current working
       directory with the log of the original changeset. The changesets are
       copied and will thus appear twice in the history with different
       identities.
       Consider using the graft command if everything is inside the same
       repository - it will use merges and will usually give a better
       result.  Use the rebase extension if the changesets are unpublished
       and you want to move them instead of copying them.
       If --log is specified, log messages will have a comment appended of
       the form:
       (transplanted from CHANGESETHASH)
       You can rewrite the changelog message with the --filter option.  Its
       argument will be invoked with the current changelog message as $1 and
       the patch as $2.
       --source/-s specifies another repository to use for selecting
       changesets, just as if it temporarily had been pulled.  If
       --branch/-b is specified, these revisions will be used as heads when
       deciding which changsets to transplant, just as if only these
       revisions had been pulled.  If --all/-a is specified, all the
       revisions up to the heads specified with --branch will be
       transplanted.
       Example:
       · transplant all changes up to REV on top of your current revision:
         hg transplant --branch REV --all
       You can optionally mark selected transplanted changesets as merge
       changesets. You will not be prompted to transplant any ancestors of a
       merged transplant, and you can merge descendants of them normally
       instead of transplanting them.
       Merge changesets may be transplanted directly by specifying the
       proper parent changeset by calling hg transplant --parent.
       If no merges or revisions are provided, hg transplant will start an
       interactive changeset browser.
       If a changeset application fails, you can fix the merge by hand and
       then resume where you left off by calling hg transplant --continue/-c
       .
       Options:
       -s, --source
              transplant changesets from REPO
       -b, --branch
              use this source changeset as head
       -a, --all
              pull all changesets up to the --branch revisions
       -p, --prune
              skip over REV
       -m, --merge
              merge at REV
       --parent
              parent to choose when transplanting merge
       -e, --edit
              invoke editor on commit messages
       --log  append transplant info to log message
       -c, --continue
              continue last transplant session after fixing conflicts
       --filter
              filter changesets through command
   win32mbcs
       allow the use of MBCS paths with problematic encodings
       Some MBCS encodings are not good for some path operations (i.e.
       splitting path, case conversion, etc.) with its encoded bytes. We
       call such a encoding (i.e. shift_jis and big5) as "problematic
       encoding".  This extension can be used to fix the issue with those
       encodings by wrapping some functions to convert to Unicode string
       before path operation.
       This extension is useful for:
       · Japanese Windows users using shift_jis encoding.
       · Chinese Windows users using big5 encoding.
       · All users who use a repository with one of problematic encodings on
         case-insensitive file system.
       This extension is not needed for:
       · Any user who use only ASCII chars in path.
       · Any user who do not use any of problematic encodings.
       Note that there are some limitations on using this extension:
       · You should use single encoding in one repository.
       · If the repository path ends with 0x5c, .hg/hgrc cannot be read.
       · win32mbcs is not compatible with fixutf8 extension.
       By default, win32mbcs uses encoding.encoding decided by Mercurial.
       You can specify the encoding by config option:
       [win32mbcs]
       encoding = sjis
       It is useful for the users who want to commit with UTF-8 log message.
   win32text
       perform automatic newline conversion
          Deprecation: The win32text extension requires each user to
          configure the extension again and again for each clone since the
          configuration is not copied when cloning.
          We have therefore made the eol as an alternative. The eol uses a
          version controlled file for its configuration and each clone will
          therefore use the right settings from the start.
       To perform automatic newline conversion, use:
       [extensions]
       win32text =
       [encode]
       ** = cleverencode:
       # or ** = macencode:
       [decode]
       ** = cleverdecode:
       # or ** = macdecode:
       If not doing conversion, to make sure you do not commit CRLF/CR by
       accident:
       [hooks]
       pretxncommit.crlf = python:hgext.win32text.forbidcrlf
       # or pretxncommit.cr = python:hgext.win32text.forbidcr
       To do the same check on a server to prevent CRLF/CR from being pushed
       or pulled:
       [hooks]
       pretxnchangegroup.crlf = python:hgext.win32text.forbidcrlf
       # or pretxnchangegroup.cr = python:hgext.win32text.forbidcr
   zeroconf
       discover and advertise repositories on the local network
       Zeroconf-enabled repositories will be announced in a network without
       the need to configure a server or a service. They can be discovered
       without knowing their actual IP address.
       To allow other people to discover your repository using run hg serve
       in your repository:
       $ cd test
       $ hg serve
       You can discover Zeroconf-enabled repositories by running hg paths:
       $ hg paths
       zc-test = http://example.com:8000/test

FILES         top

       /etc/mercurial/hgrc, $HOME/.hgrc, .hg/hgrc
              This file contains defaults and configuration. Values in
              .hg/hgrc override those in $HOME/.hgrc, and these override
              settings made in the global /etc/mercurial/hgrc configuration.
              See hgrc(5) for details of the contents and format of these
              files.
       .hgignore
              This file contains regular expressions (one per line) that
              describe file names that should be ignored by hg. For details,
              see hgignore(5).
       .hgsub
              This file defines the locations of all subrepositories, and
              tells where the subrepository checkouts came from. For
              details, see hg help subrepos.
       .hgsubstate
              This file is where Mercurial stores all nested repository
              states. NB: This file should not be edited manually.
       .hgtags
              This file contains changeset hash values and text tag names
              (one of each separated by spaces) that correspond to tagged
              versions of the repository contents. The file content is
              encoded using UTF-8.
       .hg/last-message.txt
              This file is used by hg commit to store a backup of the commit
              message in case the commit fails.
       .hg/localtags
              This file can be used to define local tags which are not
              shared among repositories. The file format is the same as for
              .hgtags, but it is encoded using the local system encoding.
       Some commands (e.g. revert) produce backup files ending in .orig, if
       the .orig file already exists and is not tracked by Mercurial, it
       will be overwritten.
