.SH Description
.\" ====================================================================
.
.I tfmtodit
creates a font description file for use with
.MR groff 1 's
.B dvi
output device.
.
.I tfm-file
is the name of the \*(tx font metric file for the font.
.
.I map-file
assigns
.I groff
ordinary or special character identifiers to glyph indices in the font;
it should consist of a sequence of lines of the form
.
.RS
.IR "i c1" \~\&.\|.\|.\&\~ cn
.RE
.
where
.I i
is a position of the glyph in the font in decimal,
and
.I c1
through
.I cn
are glyph identifiers in the form used by
.I groff
font descriptions.
.
If a glyph has no
.I groff
names but exists in
.I tfm-file,
it is put in the
.I groff
font description file as an unnamed glyph.
.
Output is written in
.MR groff_font 5
format to
.I font-description,
a file named for the intended
.I groff
font name.
.
.
.P
If the font is \[lq]special\[rq],
meaning that
.I groff
should search it whenever a glyph is not found in the current font,
use the
.B \-s
option and name
.I font-description
in the
.B fonts
directive in the output device's
.I DESC
file.
.
.
.P
To do a good job of math typesetting,
.I groff
requires font metric information not present in
.I tfm-file.
.
This is because \*(tx has separate math italic fonts,
whereas
.I groff
uses normal italic fonts for math.
.
The additional information required by
.I groff
is given by the two arguments to the
.B math_fit
macro in the Metafont programs for the Computer Modern fonts.
.
In a text font (a font for which
.B math_fit
is false),
Metafont normally ignores these two arguments.
.
Metafont can be made to put this information into the GF
(\[lq]generic font\[rq])
files it produces by loading the following definition after
.B cmbase
when creating
.IR cm.base .
.
.RS
.EX
def ignore_math_fit(expr left_adjustment,right_adjustment) =
    special "adjustment";
    numspecial left_adjustment*16/designsize;
    numspecial right_adjustment*16/designsize;
    enddef;
.EE
.RE
.
For the EC font family,
load the following definition after
.BR exbase ;
consider patching
.I exbase.mf
locally.
.
.RS
.EX
def ignore_math_fit(expr left_adjustment,right_adjustment) =
    ori_special "adjustment";
    ori_numspecial left_adjustment*16/designsize;
    ori_numspecial right_adjustment*16/designsize;
    enddef;
.EE
.RE
.
The only difference from the previous example is the \[lq]ori_\[rq]
prefix to \[lq]special\[rq] and \[lq]numspecial\[rq].
.
The GF file created using this modified
.I cm.base
or
.I exbase.mf
should be specified with the
.B \-g
option,
which should
.I not
be given for a font for which
.B math_fit
is true.

.
.B \-\-help
displays a usage message,
while
.B \-v
and

show version information;
all exit afterward.
.
.
.TP
.BI \-g \~gf-file
Use the
.I gf-file
produced by Metafont containing
.RB \[lq] special \[rq]
and
.RB \[lq] numspecial \[rq]
commands to obtain additional font metric information.
.
.
.TP
.BI \-k \~skew-char
The skew character of this font is at position
.I skew-char.
.
.I skew-char
should be an integer;
it may be given in decimal,
with a leading 0 in octal,
or with a leading 0x in hexadecimal.
.
Any kerns whose second component is
.I skew-char
are ignored.
.
.
.TP
.B \-s
Add the
.B special
directive to the font description file.
