Usage: fnrclone [-OPTIONS] <source> <destination>   
	where OPTIONS are:
        [-c (checkout any new versions of files from RCS)]
        [-s (create a script & log file in $HOME/fnrclone and
	    execute the script)]
        [-n (leave actual files, not symbolic links)]
	[-f <logfile name> (create a log file of changes)]
	[-d (descend symbolically linked directories)]
	[-S (do not follow symbolic links for files)
        [-O (do not check out files, Only create symbolic links for existing files)
	[-C (process SCCS directories[usually they are ignored])
        [-u Usage message]
NOTE: the default is make symbolic links and don't check out newer
      revisions of files, just shadow the source. If the RCS directory is 
      accessible, check out any brand new files as real files. If the
      RCS directory is not accessible (remote exchange), do NOT check out
      any brand new files.
