+      Racket (formerly called PLT Scheme) is a programming language derived

+      implementation of Racket, a JIT compiler; DrRacket, the Racket program
+      development environment; the TeachScheme! outreach, an attempt to turn
+      Computing and Programming into "an indispensable part of the liberal
+      arts curriculum"; and PLaneT, Racket's web-based package
+      distribution system for user-contributed packages.
