This directory contains the files for PLScheme, a virtual machine and
compiler developed by Jonathan Rees in 1988 for 6.821, Dave Gifford's
graduate programming languages class at MIT.  The code is written in
Scheme.

Load the files listed in the file PL.SCM in order to run the system.

VM.SCM contains a read-evaluate-print loop (repl) and a few test
definitions. You must do (initialize) before calling these. They are
(test-fact n), (test-ifact n) and (cons-a-lot).

In COMPILER.SCM and VM.SCM, the named-let name "recur" is replaced
with "loop" to avoid conflicts with the recur special form on some
schemes.
