Perhaps, but it's not as good as Heirloom Troff, which is based on the
"real" sources, but adds lots of groff's features PLUS adds a new font
system that allows for the trasparent use of unmodified Type 1,
Truetype and even OpenType (including all the fancy stuff) fonts AND
tweaks the various typesetting algorithms for MUCH nicer results.
