tfmtodit - create font files for use with groff -Tdvi
tfmtodit [ -sv ] [ -ggf_file ] [ -kskewchar ] tfm_file
tfmtodit creates a font file for use with groff -Tdvi.
tfm_file is the name of the TeX font metric file for the
font. map_file is a file giving the groff names for char-
acters in the font; this file should consist of a sequence
of lines of the form:
n c1 c2 ...
where n is a decimal integer giving the position of the
character in the font, and c1, c2,... are the groff names
of the character. If a character has no groff names but
exists in the tfm file, then it will be put in the groff
font file as an unnamed character. font is the name of
the groff font file. The groff font file is written to
The -s option should be given if the font is special (a
font is special if troff should search it whenever a char-
acter is not found in the current font.) If the font is
special, it should be listed in the fonts command in the
DESC file; if it is not special, there is no need to list
it, since troff can automatically mount it when it's first
To do a good job of math typesetting, groff requires font
metric information not present in the tfm file. The rea-
son for this is that TeX has separate math italic fonts
whereas groff uses normal italic fonts for math. The
additional information required by groff is given by the
two arguments to the math_fit macro in the Metafont pro-
grams for the Computer Modern fonts. In a text font (a
font for which math_fitting is false), Metafont normally
ignores these two arguments. Metafont can be made to put
this information in the gf file by loading the following
definition after cmbase when creating cm.base:
def ignore_math_fit(expr left_adjustment,right_adjustment) =
The gf file created using this modified cm.base should be
specified with the -g option. The -g option should not be
given for a font for which math_fitting is true.

-v Print the version number.
-s The font is special. The effect of this option is
to add the special command to the font file.
-kn The skewchar of this font is at position n. n
should be an integer; it may be given in decimal,
or with a leading 0 in octal, or with a leading 0x
in hexadecimal. The effect of this option is to
ignore any kerns whose second component is the
gf_file is a gf file produced by Metafont contain-
ing special and numspecial commands giving addi-
tional font metric information.
