/*
* NAME
* pfb2pfa - convert a type1 pfb file (binary) into a pfa (ASCII)
* SYNOPSIS
* pfb2pfa [-v] pfbfile [pfafile]
* DESCRIPTION
* Program converts a binary MSDOS representation for a type1
* PostScript font into a readable ASCII version. The MSDOS
* newline (\r) is converted into the UNIX newline (\n).
* The output is written in a file whose name is the name that
* is provided on the command line or the basename of the input
* file plus extension ".pfa".
*
* With the -v option you get some information about what the
* program is doing.
* AUTHOR
* Piet Tutelaers (rcpt@urc.tue.nl)
