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.
