vftovp - convert virtual font (vf) files to virtual property lists (vpl)
This manual page is not meant to be exhaustive. The complete documentation for
this version of TeX can be found in the info file or manual Web2C: A TeX
program translates a (program-oriented) virtual font file and
its accompanying TeX font metric file to a (human-oriented) property list
file. Thus, the virtual font can be edited, and its exact contents can be
displayed mnemonically. It also serves as a VF-file validating program; if no
error messages are given, the input files are correct.
The filenames are extended with the appropriate extension if necessary.
- The argument format specifies how character codes are output in the
VPL file. By default, only letters and digits are output using the
C integer code (i.e., in ASCII); the others are output in octal.
(Unless the font's coding scheme starts with TeX math sy or TeX
math ex, when all are output in octal.) If format is
ascii, all character codes that correspond to graphic characters,
besides the left and right parentheses, are output in ASCII. On the other
hand, if format is octal, all character codes are output in
- Without this option, vftovp operates silently. With it, a banner
and progress report are printed on stdout.
looks for vf_name
using the environment variable VFFONTS.
If that is not set, it uses the variable TEXFONTS. If that is not set, it uses
the system default.

Donald E. Knuth wrote the program, based in part on an idea of David Fuchs,
starting with the code for tftopl

compilation with web2c
