Summary: simple lndir script

	We have similar problems.  Our master source directory tree is
on a Pyramid, but we would like to be able to build stuff on each of
several different machines (Sun2, Sun3, soon Sun4, soon HP 330s and
350s, etc.).  I find the following shell script "lndir" to be very
useful.  It makes a tree of links: The directories are real, but all
files are symbolic links, usually across NFS to the actual sources.
The current exception is that anything named Makefile is copied
because that's where most of the machine customizations happen
	This script still requires some manual postprocessing.  For
example, you will need to make all your GNU Emacs *.elc files "real"
on the new directory tree if you want to be able to use workstations
while the central source machine is down.  Similarly,
emacs/src/config.h and friends are locally-customized.  X11 may
require manual local machine-specific futzing of Imakefiles, too.
	But the massive bulk of the work of building a tree of links
is done for you.  Since the script is fairly simple and very helpful,
I've included it here.  Hope this helps!
