grops/psfig.diff

   1 These are patches to makes psfig work with groff.  They apply to the
   2 version of psfig in comp.sources.unix/Volume11.  After applying them,
   3 psfig should be recompiled with -DGROFF.  The resulting psfig will
   4 work only with groff, so you might want to install it under a
   5 different name.  The output of this psfig must be processed using the
   6 macros in the file ../macros/tmac.psfig.  These will automatically add
   7 the necessary PostScript code to the prologue output by grops.  Use of
   8 the `global' feature in psfig will result in non-conformant PostScript
   9 which will fail if processed by a page reversal program.  Note that
  10 psfig is unsupported by me (I'm not interested in hearing about psfig
  11 problems.)  For new documents, I recommend using the PostScript
  12 inclusion features provided by grops.
