This is a prototype for an SCCS file browser.  

Installation
------------
	put bin/* in /usr/local/bin
	put lib/* in /usr/local/lib

Running
-------
	put /usr/local/bin in your path
	sccstool SCCS/s.foo.c

	Clicking on a rev with the left mouse gives the SCCS history for that
	rev.

	Clicking on rev1 with the middle mouse, then rev2 with the right
	mouse will produce the diffs from rev1 leading to rev2.

Future
------
	This will change to have a directory browser for selecting files,
	two text windows, one for history and one for diffs.
