vftovp - convert virtual font (vf) files to virtual property lists (vpl)
vftovp [ -charcode-format=format ] [ -verbose ] vf_name[.vf] tfm_name[.tfm] [
This manual page is not meant to be exhaustive. The complete documentation for this ver-
sion 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.
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 char-
acter 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 out-
put in octal.
Without the -verbose option, vftovp operates silently. With it, a banner and progress
report are printed on stdout.
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.

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.
