1This demonstrates the use of PNG_USER_CONFIG, pngusr.h and pngusr.dfa
2
3The makefile builds a minimal read-only decoder with embedded libpng
4and zlib.
5
6Specify the location of the zlib source (1.2.1 or later) as ZLIBSRC
7on the make command line.
8
9If you prefer to use the shared libraries, go to contrib/pngminus
10and build the png2pnm application there.
