NAME
vftovp - convert virtual font (vf) files to virtual
property lists (vpl)
SYNOPSIS
vftovp [
-charcode-format=format ] [ -verbose ]
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
The argument format to
-charcode-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.
Without the -verbose 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.
