VSCM

A highly portable implementation of {Scheme}, written in {ANSI

C} and {Scheme}. VSCM features exception and interrupt

handling, executable portable memory images, {coroutine}s and

{continuation}s with multiple arguments.

Portability is achieved by exclusive use of legal ANSI C

features -- as opposed to a plethora of #ifdef's to adjust to

various system peculiarities. (Of course, in real life ANSI C

doesn't guarantee portability per se, because there are too

many systems with broken compilers or broken libraries.)

Version II Nov9 by Matthias Blume

includes {run-time support} and a {bytecode compiler}. It

conforms to R4RS and IEEE P1178 and runs on {Unix} and

{Macintosh}. It is actively developed.
