Create a font description file from a TeX font metrics file

tfmtodit creates font description files for use with groff's DVI output device. It converts TeX Font Metrics (TFM) files into the format required by groff.
The tfmfile is the TeX font metric file for the font. The mapfile assigns groff character identifiers to glyph indices in the font, consisting of lines in the form `i c1 ... cn` where i is the glyph position and c1 through cn are glyph identifiers. Output is written in grofffont(5) format to the specified font_ file.
For math typesetting, groff requires additional font metric information not present in TFM files. This is because TeX uses separate math italic fonts while groff uses normal italic fonts for math. The additional information comes from the math_fit macro arguments in Metafont programs for Computer Modern fonts.

-s

Add the special directive to the font description file. Use when the font should be searched whenever a glyph is not found in the current font.

Use the gf file produced by Metafont containing special and numspecial commands to obtain additional font metric information.

Specify the skew character position. Any kerns whose second component is the skew character are ignored. May be given in decimal, octal (leading 0), or hexadecimal (leading 0x).

Print the version number and exit.

The tool is specifically designed for the DVI output device and may not work correctly with other groff output devices. Proper math typesetting requires supplementary font metric data from Metafont gf files via the -g option.

tfmtodit is part of the groff (GNU troff) project, which began in 1990 as a free software replacement for the Unix troff typesetting system. The tool bridges the gap between TeX font metrics and groff's font description format, enabling use of TeX fonts with groff's DVI output.
