2 *
3 * Font description file producer for imagen fonts: David Slattengren
4 * Taken from vfontinfo by Andy Hertzfeld 4/79
5 *
6 * Use: makeifont [ -nNAME ] [ -i -s -a -o -l -c ] [ "-xs1,s2[;s1,s2...]" ]
7 * [ "-ys1,s2[;s1,s2...]" ] [ -p# ] [ -r# ] [ -ddir ] font
8 *
9 * Mkfnt takes the font named "font" and produces a ditroff description
10 * file from it. The -n option takes the 1 or 2 letter troff name to put
11 * the description (default = XX). The -s, -o, -i, -a options select a
12 * different character mapping than for a "roman" font. s = special;
13 * o = math; i = italics; a = ascii. The -l option tells if the font
14 * has ligatures. The -c option tells makeifont that the font is a
15 * constant width one and sets parameters appropriately.
16 *
17 * Both -x and -y options allow character name mapping. A semi-colon
18 * separated list of comma-separated character-name pairs follows the
19 * x or y. Notice that there are no spaces in the -x or -y command. It
20 * is also IMPORTANT to enclose these arguments in single quotes to stop
21 * the cshell from interpretting the contents. A -x pair REPLACES the
22 * definition for s1 by s2. A -y pair creates a synonym for s1 and calls
23 * it s2. -x and -y MUST be sent after -s, -m, -i, or -a if one of them
24 * is used. Some synonyms are defaulted. To remove a synonym or char-
25 * acter, leave out s2.
26 *
27 * The -p# option tells what point size the DESC file has
28 * as it's "unitwidth" argument (default: 40). The -r# option is the
29 * resolution of the device (default: 240, in units/inch). The -d option
30 * tells where to find fonts (default: /usr/src/local/imagen/fonts/raster).
