++Title: A description on how to use and modify libpng (version 1.5.X)
++Author: Glenn Randers-Pehrson
++Abstract: This file describes how to use and modify the PNG reference library
++ (known as libpng) for your own use. There are five sections to this
++ file: introduction, structures, reading, writing, and modification and
++ configuration notes for various special platforms. In addition to this
++ file, example.c is a good starting point for using the library, as
++ it is heavily commented and should include everything most people
++ will need. We assume that libpng is already installed; see the
++ INSTALL file for instructions on how to install libpng.
++ .
++ Libpng was written as a companion to the PNG specification, as a way
++ of reducing the amount of time and effort it takes to support the PNG
++ file format in application programs. The PNG specification is available
++ as RFC 2083 <http://www.ietf.org/rfc/rfc2083.txt> and as a
++ W3C Recommendation <http://www.w3.org/TR/REC-png-multi.html>. Some
++ additional chunks are described in the special-purpose public chunks
++ documents at <ftp://ftp.uu.net/graphics/png/documents/>. Other information
++ about PNG, and the latest version of libpng, can be found at the PNG home
++ page, <http://www.libpng.org/pub/png/>.
