%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.

%description -n	%{develname}
The libpng-devel package contains the header files and libraries
necessary for developing programs using the PNG (Portable Network
Graphics) library.

If you want to develop programs which will manipulate PNG image format
files, you should install libpng-devel.  You'll also need to install the
libpng package.
