13 Vwidth translates from the width information stored in the vfont style
14 format to the format expected by troff. Troff wants an object file in
15 a.out(5) format. (This fact does not seem to be documented anywhere.)
16 Troff should look directly in the font file but it doesn't.
17 Vwidth should be used after editing a font with fed(1). It is not nec‐
19 essary to use vwidth unless you have made a change that would affect
20 the width tables. Such changes include numerically editing the width
21 field, adding a new character, and moving or copying a character to a
22 new position. It is not always necessary to use vwidth if the physical
23 width of the glyph (e.g. the number of columns in the bit matrix) has
24 changed, but if it has changed much the logical width should probably
25 be changed and vwidth run.
26 Vwidth produces a C program on its standard output. This program
28 should be run through the C compiler and the object (that is, the .o
29 file) saved. The resulting file should be placed in /usr/share/font in
30 the file ftxx where is a one or two letter code that is the logical
31 (internal to troff) font name. This name can be found by looking in
32 the file /usr/share/fontinfo/fname* where fname is the external name of
33 the font.

40 complains about.
