+define PKG_DESCRIPTION
+       The libpng package contains a library of functions for creating and \
+       manipulating PNG (Portable Network Graphics) image format files. \
+       PNG is a bit-mapped graphics format similar to the GIF format. PNG \
+       was created to replace the GIF format, since GIF uses a patented \
+       data compression algorithm.

++/* pngconf.h is part of the exported API. When a libpng-using application
++   includes us, PNG_CONFIGURE_LIBPNG is of course not defined as we do not have
++   libpng's config.h available in this case. This means that we do not have the
++   defines added to config.h and the commandline by libpng's ./configure .
++   
++   For all defines from config.h not having them set is not a problem, however
++   ./configure also adds -DPNG_NO_ASSEMBLER_CODE to the CFLAGS when compiling
++   on a platform on which the MMX and SSE asm code in libpng is not supported.
++   
++   We do need this define as this define is used to determine whether or not
++   to define PNG_ASSEMBLER_CODE_SUPPORTED and other assembler related defines
++   and prototypes. PNG_ASSEMBLER_CODE_SUPPORTED in turn is used by applications
++   (ImageMagick for example) to determine whether or not they can use the asm
++   functions. Thus we need to define PNG_NO_ASSEMBLER_CODE here on platforms
++   on which the MMX and SSE asm code in libpng is not supported: */
