It's in root/vendor:

    http://larceny.ccs.neu.edu/larceny-trac/browser/vendor/LexGen
    http://larceny.ccs.neu.edu/larceny-trac/browser/vendor/ParseGen

Warning:  It's an LL(1) parser generator, not LALR.

Note: src/Lib/Common/makeLexer.sch uses it.  We
might move it into src/lib/ so we can support a
programmer-customizable read or get-datum procedure.
