DESCRIPTION         top

       The pam_echo PAM module is for printing text messages to inform user
       about special things. Sequences starting with the % character are
       interpreted in the following way:
       %H
           The name of the remote host (PAM_RHOST).
       %h
           The name of the local host.
       %s
           The service name (PAM_SERVICE).

       %U
           The remote user name (PAM_RUSER).
       %u
           The local user name (PAM_USER).
       All other sequences beginning with % expands to the characters
       following the % character.
