KL1 Programming Environment on UNIX --- PDSS

PDSS --- PIMOS Development Support System is a KL1 system which was
used to develop PIMOS.  PDSS is running on ordinary BSD-UNIX machines,
and is widely compatible with the KL1 system found on Multi-PSI
besides implementation details, execution speed, etc.  Moreover PDSS
include GNU Emacs Lisp libraries to assist you in editing KL1 source
programs and to realise interactive execution through multiple emacs
buffers.  Therefore, pdss is very useful to develop KL1 programs.

Configuration:
 - KL1-B (byte code) interpreter written in C.
 - KL1 to KL1-B compilers written in KL1 and SICStus Prolog.
 - Runtime support routines (command interpreter and I/O) written in KL1.
 - GNU Emacs Libraries --- KL1-mode to edit KL1 source programs and
   PDSS-mode to run PDSS interactively through multiple emacs buffers.

Installation Environment:
 - PDSS require the UNIX system (only BSD version).
   In ICOT, We are using PDSS on SUN-3, SUN-4 and Sequent Symmetry.
 - You must provide 20MB of disk space to install the full PDSS syste.
 - One of KL1 compiler is written in SICStus Prolog.
   This is an optional tool.  However, this generate better code.
 - PDSS should be used with GNU Emacs.  It is more user-friendly.
