 * 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.
