compares the working file and a revision in the corresponding
RCS file. If it finds a difference, it does nothing.
Otherwise, it first unlocks the revision if the
option is given,
and then removes the working file
unless the working file is writable and the revision is locked.
It logs its actions by outputting the corresponding
commands on the standard output.

Pathnames matching an RCS suffix denote RCS files;
all others denote working files.
The number of the revision to which the working file is compared

- Do not actually remove any files or unlock any revisions.
Using this option will tell you what
would do without actually doing it.
- Do not log the actions taken on standard output.
- This option has no effect other than specifying the revision for comparison.
- Preserve the modification time on the RCS file
even if the RCS file changes because a lock is removed.
This option can suppress extensive recompilation caused by a
dependency of some other copy of the working file on the RCS file.
Use this option with care; it can suppress recompilation even when it is needed,
i.e. when the lock removal
would mean a change to keyword strings in the other working file.
- Unlock the revision if it is locked and no difference is found.
- Print RCS's version number.
- Emulate RCS version
to characterize RCS files.
