To compile: just type "make" in the directory containing all this stuff. 
	You will also need to add the lines contained in
	the ".Xdefaults" file to your ".Xdefaults" file
	in your home directory (-- create one if you
	don't have one).

To run: It reads its input (list of nodes) from the file
	"nodedata". Overwrite this file with your own list
	of nodes as input, if you want to work with another grid
	(see pugfile.c or ask me for the format).
	As it is packaged, "nodedata" is just a copy of 
	"wrench.dat", so if you do overwrite "nodedata"
	you can easily restore it.

	There's also a few other command line switches,
	and all the usual Xt command-line switches
	(-display, -geometry,...).
	The most important ones are "-nosolve"
	which turns off solution-finding, and "-maxdepth" which
	allows you to set the maximum depth of the triangulation.
	To see more explanation, and other non-Xt options, run "pug -h"

Please let me know of any bugs. I know it works on:
	Sparc ELC,SLC,10
	BBN GP-1000
	SGI Crimson
	IBM-PC running Linux

Sample run:
 pug -loadt fic4.tri -noout -sweeps 2000 >! output
