vptovf1
Convert tex virtual property list (vpl) files to virtual font metric (vf) files
Usage
vptovf [-verbose]
vpl_file
[.vpl]
[vfm_file
[.vf]
[tfm_file
[.tfm]]]
Overview
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.
