The current state of this software is "works pretty well"; there
have been only minor changes made in over a year.

Useful programs
	screend		daemon
	screenmode	turns screening on and off
	screenstat	prints kernel stats

Not so useful programs
	screenmini	used for timing tests
	screentest	used for testing kernel code
	ckscreentab	now obviated by "screend -c"

Program documentation (useful programs only) in the "man" subdirectory.

Concept documentation (paper in Summer 1989 USENIX conference)
in the "doc" subdirectory; PostScript format only.

Example configuration files in the "examples" subdirectory, mostly
not worth much of anything.

Kernel code (tested but no guarantees) in "sys" subdirectory.

This code should run on both Vax and PMax, but has been heavily
tested only on Vaxen.

Please obey the part in the LICENSE file that says not to redistribute
this software to anyone.
