Scheme 48 is an implementation of Scheme written by Richard Kelsey and
Jonathan Rees. It is based on a byte-code interpreter and is designed
to be used as a testbed for experiments in implementation techniques
and as an expository tool. It comes with a module system, an extensive
set of libraries, an interactive command-line-based development
environment and a manual in various formats. Scheme 48 runs on most
Unix/Linux systems, as well as Windows NT, 2000, XP, and Vista, and is
Scheme 48 is available (under a very liberal license) from
