 Much of the parser generated by Bison is copied verbatim from a file
 called @file{bison.simple}.  If Bison cannot find that file, or if you
 would like to direct Bison to use a different copy, setting the
 environment variable @code{BISON_SIMPLE} to the path of the file will
 cause Bison to use that copy instead.
