+$#      zlib.lib.
+$#
+$#   2) If you want to change libpng to a non-standard configuration also
+$#      change the definition of 'awk' in the before rule to the name of your

+$# If emtpy the standard configuration will be built.  For this file to be
+$# used a working version of the program 'awk' is required and the program
+$# must be identified in the 'before' rule of the project.
+$#
+$# If you don't already have 'awk', or the version of awk you have seems not
+$# to work, download Brian Kernighan's awk (Brian Kernighan is the author of
+$# awk.)  You can find source code and a built executable (called awk95.exe)
+$# here:
+$#
+$#     http://www.cs.princeton.edu/~bwk/btl.mirror/
+$#
+$# The executable works just fine.
+$#
+$# If build issues errors after a change to pngconfig.dfa you have entered
+$# inconsistent feature requests, or even malformed requests, in
+$# pngconfig.dfa.  The error messages from awk should be comprehensible, but
+$# if not simply go back to the start (nothing but comments in this file) and
+$# enter configuration lines one by one until one produces an error.  (Or, of
+$# course, do the standard binary chop.)
+$#
+$# You need to rebuild everything after a change to pnglibconf.dfa - i.e. you
+$# must do Actions/Mark All Targets for Remake.  This is because the compiler
+$# generated dependency information (as of OpenWatcom 1.9) does not record the
+$# dependency on pnglibconf.h correctly.
+$#
+$# If awk isn't set then this file is bypassed.  If you just want the standard
+$# configuration it is automatically produced from the distributed version
+$# (scripts\pnglibconf.h.prebuilt) by editting PNG_API_RULE to 2 (to force use
+$# of the OpenWatcom library calling convention.)

+Assumptions:
+* The libpng source files are in ..\..
+* The zlib source files are in ..\..\..\zlib
+* The zlib project file is in . /* Warning: This is until the zlib project
+  files get intergrated into the next zlib release. The final zlib project
+  directory will then be ..\..\..\zlib\projects\visualc71. */
+
+To use:
+
+1) On the main menu, select "File | Open Solution".
+   Open "libpng.sln".
+
+2) Display the Solution Explorer view (Ctrl+Alt+L)
+
+3) Set one of the project as the StartUp project. If you just want to build the
+   binaries set "libpng" as the startup project (Select "libpng" tree view
+   item + Project | Set as StartUp project). If you want to build and test the
+   binaries set it to "pngtest" (Select "pngtest" tree view item +
+   Project | Set as StartUp project)
+
+4) Select "Build | Configuration Manager...".
+   Choose the configuration you wish to build.
+
+5) Select "Build | Clean Solution".
+
+6) Select "Build | Build Solution (Ctrl-Shift-B)"
+
+This project builds the libpng binaries as follows:
+
+* Win32_DLL_Release\libpng15.dll      DLL build
+* Win32_DLL_Debug\libpng15d.dll       DLL build (debug version)
+* Win32_DLL_VB\libpng15vb.dll         DLL build for Visual Basic, using stdcall
+* Win32_LIB_Release\libpng.lib        static build
+* Win32_LIB_Debug\libpngd.lib         static build (debug version)
+
+Notes:
+
+If you change anything in the source files, or select different compiler
+settings, please change the DLL name to something different than any of
+the above names. Also, make sure that in your "pngusr.h" you define
+PNG_USER_PRIVATEBUILD and PNG_USER_DLLFNAME_POSTFIX according to the
+instructions provided in "pngconf.h".
+
+All DLLs built by this project use the Microsoft dynamic C runtime library
+MSVCR71.DLL (MSVCR71D.DLL for debug versions).  If you distribute any of the
+above mentioned libraries you may have to include this DLL in your package.
+For a list of files that are redistributable in Visual Studio see
+$(VCINSTALLDIR)\redist.txt.

+libpng version 1.5.9 - February 18, 2012
+
+Copyright (c) 1998-2010 Glenn Randers-Pehrson
+
+This code is released under the libpng license.
+For conditions of distribution and use, see the disclaimer
+and license in png.h
+
+This directory  contains support for building libpng under MicroSoft
+VisualStudio 2010.  It may also work under later versions of VisualStudio.
+You should be familiar with VisualStudio before using this directory.
+
+Initial preparations
+====================
+You must enter some information in zlib.props before attempting to build
+with this 'solution'.  Please read and edit zlib.props first.  You will
+probably not be familiar with the contents of zlib.props - do not worry,
+it is mostly harmless.
+
+This is all you need to do to build the 'release' and 'release library'
+configurations.
+
+Debugging
+=========
+The release configurations default to /Ox optimization.  Full debugging
+information is produced (in the .pdb), but if you encounter a problem the
+optimization may make it difficult to debug.  Simply rebuild with a lower
+optimization level (e.g. /Od.)
+
+Linking your application
+========================
+Normally you should link against the 'release' configuration.  This builds a
+DLL for libpng 1.5 with the default runtime options used by Visual Studio
+2010.  In particular the runtime library is the "MultiThreaded DLL" version.
+If you use Visual Studio defaults to build your application you will have no
+problems.
+
+If you don't use the Visual Studio defaults your application must still be built
+with the default runtime option (/MD).  If, for some reason, it is not then your
+application will crash inside libpng15.dll as soon as libpng tries to read
+from a file handle you pass in.
+
+If you do not want to use the DLL, for example for a very small application,
+the 'release library' configuration may be more appropriate.  This is built
+with a non-standard runtime library - the "MultiThreaded" version.  When you
+build your application it must be compiled with this option (/MT), otherwise
+it will not build (if you are lucky) or crash (if you are not.)
+
+Stop reading here
+=================
+You have enough information to build a working application.
+
+Debug versions have limited support
+===================================
+This solution includes limited support for debug versions of libpng.  You
+do not need these unless your own solution itself uses debug builds (it is
+far more effective to debug on the release builds, there is no point building
+a special debug build.)
+
+The debug build of libpng is minimally supported.  Support for debug builds of
+zlib is also minimal.  You really don't want to do this.
