@**Parser tables. This is the main table output code. Its core comes from the Bison
Sourcer(er?) (\.{bs.w}) which will be included as soon as this paragraph is
over. Since the main function of this code is to {\it dump\/} tables
produced by \bison, and a {\it bison\/} is a large buffalo like
animal, {\it and\/} the only reason it has to be done like this is due
to the less than optimal choices of a few developers, feel free to
interpret the acronym as something easier to remember.
