description         Scheme byte-code interpreter
long_description    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.
