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 parser}s ({LL parser}s) and
        {bottom-up parser}s ({LR parser}s), which will automatically
        generate {derivation tree}s, {abstract syntax tree}s or
        arbitrary {Smalltalk} {object}s.  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
