%description
The zlib compression library provides in-memory compression and decompression
functions, including integrity checks of the uncompressed data.  This version
of the library supports only one compression method (deflation), but other
algorithms may be added later, which will have the same stream interface.  The
zlib library is used by many different system programs.

Summary: Header files and libraries for developing apps which will use zlib.
Group: Development/Libraries
Requires: zlib

%description devel
The zlib-devel package contains the header files and libraries needed to
develop programs that use the zlib compression and decompression library.

Install the zlib-devel package if you want to develop applications that will
use the zlib library.
