 +%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.
 +
 +Libpng should be installed if you need to manipulate PNG format image
 +files.
