1. Purpose of the package
=========================
This package contains the png2pdf program. This program converts PNG
images to PDF files. It can use the PNG alpha channel to mix against
a background (either from the PNG file's background chunk or user
specified) and/or to create an image mask or PDF alpha channel.

This software is released under a BSD-style license.
See the file bsdlic.txt for details.
