directory that contains extensive information on using the PCN System.
(The Postscript version of the manual is in the file
"docs/pcn_prog_v2.0.ps".)  This manual contains a description of the
PCN programming language, instructions on running the system,
reference material, and much more...

This PCN manual can also be obtained by anonymous ftp from:

In addition, please consult the RELEASE_NOTES file for information on
features that are not described in the manual, or things that have
changed since the manual was written.
