%description
LibMNG is a library for accessing graphics in MNG (Multi-image Network
Graphics) and JNG (JPEG Network Graphics) formats.  MNG graphics are
basically animated PNGs.  JNG graphics are basically JPEG streams
integrated into a PNG chunk.

The library is available as 32-bit and 64-bit.

%description devel
LibMNG is a library for accessing MNG and JNG format graphics.  The
libmng-devel package contains files needed for developing or compiling
applications which use MNG graphics.

If you are compiling a 32-bit program, no special compiler options are
needed.

If you are compiling a 64-bit program, you have to compile and link your
application with "xlc -q64" or "gcc -maix64".
