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). -L FILE Use rlog-format FILE for source of logs. -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.
