Implementations

This is an extremely short list of available Scheme implementations (environments, libraries, etc.). It mainly contains those that I have used, or those I am interested in.

(Because Scheme is such a simple language practically anyone can cook-up an implementation in a matter of hours --- I know, because I did one once.) :)
