# RCS to ChangeLog generator
# Generate a change log prefix from RCS files (perhaps in the CVS repository)
# and the ChangeLog (if any).
# Output the new prefix to standard output.
# You can edit this prefix by hand, and then prepend it to ChangeLog.
# Ignore log entries that start with `#'.
# Clump together log entries that start with `{topic} ',
# where `topic' contains neither white space nor `}'.
Help='The default FILEs are the files registered under the working directory.
Options:
-c CHANGELOG Output a change log prefix to CHANGELOG (default ChangeLog).
-h HOSTNAME Use HOSTNAME in change log entries (default current host).
-i INDENT Indent change log lines by INDENT spaces (default 8).
-l LENGTH Try to limit log lines to LENGTH characters (default 79).
-R If no FILEs are given and RCS is used, recurse through working directory.
-r OPTION Pass OPTION to subsidiary log command.
-t TABWIDTH Tab stops are every TABWIDTH characters (default 8).
-u "LOGIN<tab>FULLNAME<tab>MAILADDR" Assume LOGIN has FULLNAME and MAILADDR.
-v Append RCS revision to file names in log lines.
--help Output help.
--version Output version number.
Report bugs to <bug-gnu-emacs@gnu.org>.'
