NAME
vftovp - convert virtual font (vf) files to virtual property lists (vpl)
SYNOPSIS
vftovp [OPTIONS] vf_name[.vf] [tfm_name[.tfm] [vpl_name[.vpl]]]
DESCRIPTION
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 implementation.
The vftovp 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.
OPTIONS
-charcode-format=format
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 octal.
-verbose
Without this option, vftovp operates silently. With it, a banner and progress report are printed
on stdout.
ENVIRONMENT
vftovp 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.
See tex(1) for the details of the searching.

AUTHORS
Donald E. Knuth wrote the program, based in part on an idea of David Fuchs, starting with the code for
tftopl(1). Karl Berry adapted it for compilation with web2c.
