A portable Scheme library providing compatibility and utility functions for standard Scheme implementations. By Audrey Jaffer, author of SCM.

A module proposal for Scheme by Audrey Jaffer.

An extension of the Scheme programming language to support research in computer vision.

For DrScheme, semi-structured program editing; an alternative set of key bindings. When it is on, the most important functions can run via unchorded keystrokes, and motion commands work on sexps by default.
