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 com-
plete 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 pro-
gram; 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 char-
acter 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.
