++Version: 1.6.39
++Release: 0
+License: Libpng
+Summary: A library of functions for manipulating PNG image format files
+Url: http://www.libpng.org/pub/png/libpng.html
+Group: System/Libraries
+Source: %{name}-%{version}.tar.bz2
+Source1001: libpng.manifest
+
+BuildRequires: cmake
+BuildRequires: zlib-devel
+
+%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.
+
+%package devel
+Summary: Development tools for programs to manipulate PNG image format files
+Group: Development/Libraries
+Requires: %{name} = %{version}-%{release}
+Requires: zlib-devel
+
+%description devel
+The libpng-devel package contains header files and documentation necessary
+for developing programs using the PNG (Portable Network Graphics) library.
