rbison generates a Ruby parser class from a Bison-like specification
file. rbison uses Bison to do all the hard work (generating state
transition tables, etc), then translates the Bison-generated C code into
Ruby code. 

Changes: A few small bug fixes. yytranslate() now inlined for better
performance.
