- *
- * Where "command" is composed of:
- * admin RCS command
- * checkout Check out a module/dir/file
- * export Like checkout, but used for exporting sources
- * update Brings work tree in sync with repository
- * commit Checks files into the repository
- * diff Runs diffs between revisions
- * log Prints "rlog" information for files
- * login Record user, host, repos, password
- * add Adds an entry to the repository
- * remove Removes an entry from the repository
- * status Status info on the revisions
- * rdiff "patch" format diff listing between releases
- * tag Add/delete a symbolic tag to the RCS file
- * rtag Add/delete a symbolic tag to the RCS file
- * import Import sources into CVS, using vendor branches
- * release Indicate that Module is no longer in use.
- * history Display history of Users and Modules.
