%description
Zstd, short for Zstandard, is a fast lossless compression algorithm,
targeting real-time compression scenarios at zlib-level compression ratio.

%package -n pzstd
Summary: Parallel Zstandard tool
Group: %group
Requires: %name = %EVR

%description -n pzstd
Parallel Zstandard is a Pigz-like tool for Zstandard.

It provides Zstandard format compatible compression and decompression
that is able to utilize multiple cores.  It breaks the input up into
equal sized chunks and compresses each chunk independently into a
Zstandard frame.  It then concatenates the frames together to produce
the final compressed output.  Pzstandard will write a 12 byte header for
each frame that is a skippable frame in the Zstandard format, which
tells PZstandard the size of the next compressed frame.

PZstandard supports parallel decompression of files compressed with
PZstandard.  When decompressing files compressed with Zstandard,
PZstandard does IO in one thread, and decompression in another.

%package -n lib%name
Summary: Zstd compression shared library
Group: System/Libraries

%description -n lib%name
Zstd, short for Zstandard, is a fast lossless compression algorithm,
targeting real-time compression scenarios at zlib-level compression ratio.

This package contains lib%name shared library.

%package -n lib%name-devel
Summary: Zstd compression development files
Group: Development/C
Requires: lib%name = %EVR

%description -n lib%name-devel
Zstd, short for Zstandard, is a fast lossless compression algorithm,
targeting real-time compression scenarios at zlib-level compression ratio.

This package contains development files required to build applications
using lib%name library.
