The NSPR, NSS and related projects have stopped using Mozilla'a CVS server, but have migrated to 
 Mozilla's HG (Mercurial) server.
 
 Each project now lives in its own separate space, they can be found at: 
   https://hg.mozilla.org/projects/nspr/
   https://hg.mozilla.org/projects/nss/
   https://hg.mozilla.org/projects/jss/
   https://hg.mozilla.org/projects/python-nss/
This migration has been used as an opportunity to change the layout of the 
 source directories. 
 
 For NSPR, "mozilla/nsprpub" has been removed from the directory 
 hierarchy, all files now live in the top directory of the NSPR 
 repository. 
 
 Likewise for NSS and JSS, "mozilla/security" has been removed and files 
 now live at the top level. In addition for NSS, we have merged the 
 contents of directories mozilla/dbm and mozilla/security/dbm into the 
 new directory lib/dbm. 
 
 Besides the new layout, the build system hasn't changed. Most parts of 
 the NSS build instructions remain valid, especially the instructions 
 about setting environment variables. 
 
 Updated instructions for building NSS with NSPR can be found at: 
 https://developer.mozilla.org/en-US/docs/NSS_reference/Building_and_installing_NSS/Build_instructions
 
 It's best to refer to the above document to learn about the various 
 environment variables that you might have to set to build on your 
 platform (this part hasn't changed). 
 
 However, below is a brief summary that shows how to checkout the 
 source code and build both NSPR and NSS: 
   mkdir workarea 
   cd workarea 
   hg clone https://hg.mozilla.org/projects/nspr
   hg clone https://hg.mozilla.org/projects/nss
   cd nss 
   # set USE_64=1 on 64 bit architectures 
   # set BUILD_OPT=1 to get an optimized build 
   make nss_build_all 
 
 Note that the JSS project has been given a private copy of the former 
 mozilla/security/coreconf directory, allowing it to remain stable, 
 and only update its build system as necessary. 
 
 Because of the changes described above, we have decided to use a new 
 series of (minor) version numbers. The first releases using the new code 
 layout will be NSPR 4.10 and NSS 3.15
