- * Add
- *
- * Adds a file or directory to the RCS source repository. For a file,
- * the entry is marked as "needing to be added" in the user's own CVS
- * directory, and really added to the repository when it is committed.
- * For a directory, it is added at the appropriate place in the source
- * repository and a CVS directory is generated within the directory.
- *
- * The -m option is currently the only supported option. Some may wish to
- * supply standard "rcs" options here, but I've found that this causes more
- * trouble than anything else.
- *
- * The user files or directories must already exist. For a directory, it must
- * not already have a CVS file in it.
- *
- * An "add" on a file that has been "remove"d but not committed will cause the
- * file to be resurrected.
