драйвер вывода groff для PostScript (groff output driver for PostScript)
Old fonts
groff versions 1.19.2 and earlier contain a slightly different
set of the 35 Adobe core fonts; the difference is mainly the lack
of the 'Euro' glyph and a reduced set of kerning pairs. For
backwards compatibility, these old fonts are installed also in
the
/usr/local/share/groff/1.23.0/oldfont/devps
directory.
To use them, make sure that grops finds the fonts before the
default system fonts (with the same names): Either add command-
line option -F to grops
groff -Tps -P-F -P/usr/local/share/groff/1.23.0/oldfont
...
or add the directory to groff's font path environment variable
GROFF_FONT_PATH=/usr/local/share/groff/1.23.0/oldfont
