NAME
       vptovf - convert TeX virtual property list (vpl) files to virtual font
       metric (vf) files

SYNOPSIS
       vptovf [-verbose] vpl_file[.vpl] [vfm_file[.vf] [tfm_file[.tfm]]]

DESCRIPTION
       The vptovf program translates a (plain text) property list file to a
       pair of (binary) files in vf (virtual font) and tfm (TeX font metric)
       formats.  Thus, a virtual font file can be edited and its exact
       contents can be displayed mnemonically. New virtual fonts, which map
       characters as seen by TeX into an arbitrary sequence of low-level
       typesetting operations, can also be created in this way. See vftovp(1)
       for detailed references on virtual fonts.

       All three filenames, vpl_file, vf_file, and tfm_file, are extended with
       the appropriate suffix if necessary. No path searching is done for the
       vpl_file.

OPTIONS
       By default, the program operates silently. With -verbose, some reports
       are written to stdout.  The standard -help and -version options are
       also supported.

AUTHORS
       Donald E. Knuth wrote the program, based in part on an idea of David
       Fuchs, starting with the code for pltotf(1).  Karl Berry adapted it for
       compilation with web2c.
