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