Pucked Plugins

This is the home of Friar Puck's version of MIT/GNU Scheme, mit-scheme-pucked. If you arrived here without knowing who Puck is or why he might create an experimental version of mit-scheme return whence ye came!

New users should start with the user manual. Experienced users might skip straight to the release notes.

All of the packages built at Birchwood Abbey are signed by the code master, whose public GPG key can be found here.
