-f[rev]:      force a deposit (check in?)
-k[rev]:      ?
-q[rev]:      quiet mode
-i[rev]:      initial check in, errors if RCS file already exists.
-j[rev]:      just checkin and do not initialize, errors if RCS file already exists.
-I[rev]:      user is prompted even if stdin is not a tty
-d[date]:     uses date for checkin dat and time.
-M[rev]:      set modification time on any new working file to be that of the retrieved version.
