+    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.
