Options:
-r | -r[rev]: check in revision rev
-l[rev]: ", but do co -l
-u[rev]: ", but do co -u
-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 date and time.
-M[rev]: set modification time on any new working file to be that of the retrieved version.
-mmsg: msg is the log message, don't start editor. log messages with #are comments.
