Usage: $0 [ -m title ] [ -f file ] [ -c yes|no ] [ -C user:pass ]
where:

-m title        Provide title for the journal entry
                (default is command name-based)
-f file         Read the journal entry from FILE instead of STDIN
-c yes|no       Allow or disallow comments
                (default is to let your use.perl.org default stand)
-C user:pass    Provide authentication credentials in place of (or in
                absence of) Netscape cookie authentication. User in
                this case is UID, not nickname.
