%description
LZ4 is an extremely fast loss-less compression algorithm, providing compression
speed at 400 MB/s per core, scalable with multi-core CPU. It also features
an extremely fast decoder, with speed in multiple GB/s per core, typically
reaching RAM speed limits on multi-core systems.

The library is available as 32-bit and 64-bit.

Requires:       %{name} = %{version}-%{release}

%description    devel
This package contains the header(.h) and library(.so) files required to build
applications using liblz4 library.

If you are compiling a 32-bit program, no special compiler options are
needed.

If you are compiling a 64-bit program, you have to compile and link your
application with "cc_r -q64" or "gcc -maix64".
