VFTOVP(1)

NAME
vftovp - convert virtual font (vf) files to virtual property lists

SYNOPSIS
vftovp [-verbose] [-charcode-format=format] vf_file_name tfm_file_name [vpl_file_name]

DESCRIPTION
The vftovp program translates a (program-oriented) virtual font file and its accompanying 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 vpl_file_name, must be complete. No adding of default extensions is done.

ENVIRONMENT
vftovp looks for vf_file_name first in the current directory. If it is not present there, it uses the environment variable VFFONTS. If that is not set, it uses the variable TEXFONTS. If this is not set, it uses the system defaults:
VFFONTS: TEXFONTS,
TEXFONTS: /usr/TeX/lib/tex/fonts//:.,
See tex(1) for the details of the searching.

OPTIONS
Without the -verbose option, vftovp operates silently. With it, a banner and progress report are printed on stdout.

The argument format to -charcode-format specifies how character codes are output in the PL 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 TeXmathex, that is, 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.

See tex(1) for the details of specifying options.

AUTHORS
Donald 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.
