%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.

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

%description devel-static
This package contains the static library needed to develop statically linked
programs that use the zlib compression and decompression library.
