vwidth - make troff width table for a font
vwidth fontfile pointsize > ftxx.c
cc -c ftxx.c mv ftxx.o /usr/share/font/ftxx
Vwidth translates from the width information stored in the vfont style format to the for-
mat expected by troff. Troff wants an object file in a.out(5) format. (This fact does
not seem to be documented anywhere.) Troff should look directly in the font file but it
Vwidth should be used after editing a font with fed(1). It is not necessary to use vwidth
unless you have made a change that would affect the width tables. Such changes include
numerically editing the width field, adding a new character, and moving or copying a char-
acter to a new position. It is not always necessary to use vwidth if the physical width
of the glyph (e.g. the number of columns in the bit matrix) has changed, but if it has
changed much the logical width should probably be changed and vwidth run.
Vwidth produces a C program on its standard output. This program should be run through
the C compiler and the object (that is, the .o file) saved. The resulting file should be
placed in /usr/share/font in the file ftxx where is a one or two letter code that is the
logical (internal to troff) font name. This name can be found by looking in the file
/usr/share/fontinfo/fname* where fname is the external name of the font.

Produces the C file using obsolete syntax that the portable C compiler complains about.
