%description
bzip2 is a freely available, patent-free, high quality data compressor.

bzip2 compresses files using the Burrows-Wheeler block sorting text
compression algorithm and Huffman coding.  Compression is generally
considerably better than that achieved by more conventional
LZ77/LZ78-based compressors (such as gzip), and approaches the
performance of the PPM family of statistical compressors.  bzip2 is
by far not the fastest compression utility, but it does strike a
balance between speed and compression capability.

The command-line options are deliberately very similar to those of
GNU Gzip, but they are not identical.

%description -n bzlib
The bzip2 compression library provides in-memory compression and
decompression functions, including integrity checks of the uncompressed
data.  The bzip2 library is used by many different system programs.

%description -n bzlib-devel
This package contains the include files needed to develop programs that
use the bzip2 compression and decompression library.

%description -n bzlib-devel-static
This package contains the static library needed to develop statically
linked programs that use the bzip2 compression and decompression
library.
