mit-scheme-dbg - 12.1-4 main

MIT/GNU Scheme is an implementation of the Scheme programming language,
providing an interpreter, compiler, source-code debugger, integrated
Emacs-like editor, and a large runtime library. MIT/GNU Scheme is best
suited to programming large applications with a rapid development
cycle.
.
This package contains debugging files for the development
environment. These files provide support for debugging the MIT/GNU
Scheme system, and are useful only if you need to see the system
internals while you are debugging.
