T-gen

   A general-purpose object-oriented tool for the automatic
   generation of string-to-object translators.  It was written
   in Smalltalk by Justin Graver  and runs
   in the Smalltalk programming environment.  T-gen supports the
   generation of both top-down parsers (LL parsers) and
   bottom-up parsers (LR parsers), which will automatically
   generate derivation trees, abstract syntax trees or
   arbitrary Smalltalk objects.  The simple specification
   syntax and graphical user interface are intended to
   enhance the learning, comprehension and usefulness of T-gen.

   Runs on Smalltalk-80, ParcPlace Objectworks/Smalltalk
   4.0 or 4.1.
