%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.

%package devel
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.
