The regexp package used by tf is Copyright (c) 1986 by University of
Toronto.

   This is an altered version.  Changes include:

   1. Minor changes in regexp.h for cleaner integration into TinyFugue,
      which should have no effect on the package's portability.

   2. The original Makefile has been renamed original.mak; the
      new Makefile contains only enough to compile regexp.o for use with
      TinyFugue.
