Microsoft Developer Studio Build File, Format Version 6.00 for
libpng 1.0.12 (June 8, 2001) and zlib

Copyright (C) 2000 Simon-Pierre Cadieux

Assumes that libpng sources are in ..\..
Assumes that zlib sources have been copied to ..\..\..\zlib

To build:

1) On the main menu Select "Build|Set Active configuration". 
   Among the configurations beginning with "libpng" select the 
   one you wish to build (the corresponding "zlib" configuration
   will be built automatically).

2) Select "Build|Clean"

3) Select "Build|Rebuild All"

4) Look in the appropriate "win32" subdirectories for both "zlib"
   and "libpng" binaries.

This project will build the PNG Development Group's "official" versions of
libpng and zlib libraries:

   libpng2.dll          (default version, currently C code only)
   libpng2.dll         (C + Assembler version)
   libpng2.dll         (C + Assembler debug version)
   libpng2.dll         (C code debug version)
   libpng2[c,e-m].dll   (reserved for official versions) 
   libpng2[n-z].dll     (available for private versions)
   zlib.dll             (default version, currently C code only)
   zlibd.dll            (debug version)

If you change anything in libpng, or select different compiler settings,
please change the library name to an unreserved name, and define
DLLFNAME_POSTFIX and (PRIVATEBUILD or SPECIALBUILD) accordingly. DLLFNAME_POSTFIX
should correspond to a string in the range of "N" to "Z" depending on the letter 
you choose for your private version.

All DLLs built by this project use the Microsoft dynamic C runtime library
MSVCRT.DLL (MSVCRTD.DLL for debug versions). If you distribute any of the
above mentioned libraries you should also include this DLL in your package.
