%description
zlib is a general-purpose lossless data-compression library,
implementing an API for the DEFLATE algorithm, the latter of
which is being used by, for example, gzip and the ZIP archive
format.

%description devel
zlib is a general-purpose lossless data-compression library,
implementing an API for the DEFLATE algorithm, the latter of
which is being used by, for example, gzip and the ZIP archive
format.

This subpackage holds the development headers for the library.

The zlib data format is itself portable across platforms. Unlike the
LZW compression method used in unix compress(1) and in the GIF image
format, the compression method currently used in zlib essentially
never expands the data. (LZW can double or triple the file size in
extreme cases.) zlib's memory footprint is also independent of the
input data and can be reduced, if necessary, at some cost in
compression.

%package devel-static
Summary:        Static library for zlib

which is being used by, for example, gzip and the ZIP archive
format.

This subpackage contains the static version of the library
used for development.
