#   This script calls the undocumented vgrind back end "vfontedpr"
#   directly because /usr/ucb/vgrind is badly (& differently) broken
#   on both Vax (4.3 Mt Xinu) and Sun (3.5); for example, try a  simple
#   "TROFF=cat vgrind foo.c".

#   Note that we allow "-s 12" and "-dfile" as well as the "-s12" and "-d file"
#   forms vgrind insists on; but we still don't allow "-fn" for "-f -n".

#   vgrindefs below are based on efforts of Roger Hayes, Doug Cook, Ron Olsson.
