There are several areas where documentation is kept on this system.
Most important are:

[S,DOC]		Stanford Artificial Intelligence Laboratory Operating
		Notes (SAILONS).  These are usually manuals for
		systems programs.
[UP,DOC]	User Program Documentation.

The extension for files on [*,DOC] are usually the initials of its
maintainer.

Brief description of system programs may be found on PRUNE.DAT[1,3].
Many users also maintain PRUNE.DAT files which may occasionally be
helpful.
