option and its parameter.

ttffmmttooddiitt creates a font file for use with ggrrooffff --TTddvvii.
_t_f_m___f_i_l_e is the name of the TeX font metric file for the
font. _m_a_p___f_i_l_e 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 _c_1 _c_2 ...
where _n is a decimal integer giving the position of the
character in the font, and _c_1, _c_2,... 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. _f_o_n_t is the name of
the groff font file. The groff font file is written to
_f_o_n_t.
The --ss option should be given if the font is special (a
font is _s_p_e_c_i_a_l if ttrrooffff 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 ffoonnttss command in the
DESC file; if it is not special, there is no need to list
it, since ttrrooffff can automatically mount it when it's first
used.
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 mmaatthh__ffiitt macro in the Metafont pro
grams for the Computer Modern fonts. In a text font (a
font for which mmaatthh__ffiittttiinngg 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 ccmmbbaassee when creating ccmm..bbaassee:
ddeeff iiggnnoorree__mmaatthh__ffiitt((eexxpprr lleefftt__aaddjjuussttmmeenntt,,rriigghhtt__aaddjjuussttmmeenntt)) ==
ssppeecciiaall ""aaddjjuussttmmeenntt"";;
nnuummssppeecciiaall lleefftt__aaddjjuussttmmeenntt**1166//ddeessiiggnnssiizzee;;
nnuummssppeecciiaall rriigghhtt__aaddjjuussttmmeenntt**1166//ddeessiiggnnssiizzee;;
eennddddeeff;;
The gf file created using this modified ccmm..bbaassee should be
specified with the --gg option. The --gg option should not be
given for a font for which mmaatthh__ffiittttiinngg is true.
OOPPTTIIOONNSS
--vv Print the version number.
--ss The font is special. The effect of this option is
to add the ssppeecciiaall command to the font file.
--kk_n The skewchar of this font is at position _n. _n
should be an integer; it may be given in decimal,
or with a leading 00 in octal, or with a leading 00xx
in hexadecimal. The effect of this option is to
ignore any kerns whose second component is the
specified character.
--gg_g_f___f_i_l_e
_g_f___f_i_l_e is a gf file produced by Metafont contain
ing special and numspecial commands giving addi
tional font metric information.
