Yeah, it's confusingly part of the mom macro package documentation,
even though it's a general-purpose groff script.  See
http://www.schaffter.ca/mom/mom-06.html#install-font.

It doesn't so much let groff natively understand modern fonts as
convert those fonts into a form groff does understand (Type 1
PostScript) and install them in a place groff checks automatically.
By default this requires root privs, though if you don't have them,
you can work around it by setting GROFF_FONT_PATH to point to where
you've installed them.
