SCM is a
Scheme
implementation
conforming
to
Revised
Report on the
Algorithmic Language Scheme
and the IEEE P1178
specification

Scm is written in C and runs under Amiga, Atari-ST, GNU/Linux, MacOS,
MS-DOS, MS-Vista, MS-Windows, OS/2, NOS/VE, Unicos, VMS, Unix and
similar systems.
SCM includes Hobbit, the Scheme-to-C compiler originally written by
Tanel Tammet. Hobbit generates C files whose binaries can be
dynamically or statically linked with a SCM executable. SCM includes
linkable modules for sequence-comparison, arrays, records, and
byte-number conversions; and modules for POSIX system calls and
network-sockets, readline, ncurses, and Xlib.
On some platforms SCM supports unexec (developed for Emacs and bash),
which dumps a executable image from a running SCM. This results in
very low latency (12.ms) startup for SCM.
SCM requires the
SLIB Scheme Library
Both SCM and SLIB are
GNU packages
