+ 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.psfig in this directory.  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.
