%description
Gf2x is a C/C++ software package containing routines for fast arithmetic
in GF(2)[x] (multiplication, squaring, GCD) and searching for
irreducible/primitive trinomials.

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

Summary:        Headers and library files for %{name}
Group:          Applications/Engineering
Requires:       %{name} = %{version}-%{release}

%description devel
Headers and library files for developing applications that use %{name}.

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 "xlc_r -q64" or "gcc -maix64".
