.TH VPTOVF 1 "7 Jan 92"
.SH NAME
vptovf - convert virtual property lists to virtual font metrics
.SH SYNOPSIS
.B vptovf
[-verbose] vpl_file_name vfm_file_name tfm_file_name
.SH DESCRIPTION
The 
.I vptovf
program translates a (human-oriented) property list file to a pair of
(program-oriented) files in the 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.
.PP
All three file names,
.I vpl_file_name,
.I vf_file_name,
and
.I tfm_file_name,
must be complete. No adding of default extensions or path searching is done.
.SH OPTIONS
Without the
.I -verbose
option,
.I vptovf
operates silently.  With it, a banner and progress report are printed on
.IR stdout .
See
.BR tex (1)
for the details of specifying options.
