/* 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
