-/* From the original /bin/sh script:
-
- Used to create a copy of the a directory tree that has links for all
- non-directories (except those named RCS, SCCS or CVS.adm). If you are
- building the distribution on more than one machine, you should use
- this technique.
-
- If your master sources are located in /usr/local/src/X and you would like
- your link tree to be in /usr/local/src/new-X, do the following:
-
- % mkdir /usr/local/src/new-X
- % cd /usr/local/src/new-X
- % lndir ../X
