psfig.diff

早期freebsd实现

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 ../macros/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.
