I saw mention somewhere of a Bison %semantic_parser directive. Near
as I can tell, it causes bison.hairy to be used instead of
bison.simple, and it seems to be somehow tied in with another
directive, %guard.


I cannot, however, find any mention of these directives in the online
documentation. What do they do? How does a hairy parser differ from
a simple one? If someone could point me to some FTP'able
documentation, I would be most grateful.
