patch for the infamous antiquotation font-lock problem of Proof General 3.7.1 with GNU Emacs, cf. http://proofgeneral.inf.ed.ac.uk/trac/ticket/236

#!/usr/bin/env bash
#
# make-metis - turn original Metis files into Isabelle ML source.
#
# Structure declarations etc. are made local by wrapping into a
# collective structure Metis.  Signature and functor definitions are
# global!
