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


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


 DESCRIPTION
      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 vpl_file_name must be complete; no adding of default extensions is
      done.


 OPTIONS
      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 TeX math ex, 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.


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


 ENVIRONMENT
      vftovp looks for vf_file_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:
      !!/opt/teTeX/texmf/fonts/vf//:.


      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.
