%description
A free open source portable library to provide access to polynomials of finite
characteristic of varying degrees (it will grow to accomodate) written entirely
in C.  The library is designed to provide a simple to work with API that
provides fairly efficient routines that build out of the box without
configuration.

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


%package        devel
Summary:        Development files for %{name}
Group:          Development/Libraries
Requires:       %{name} = %{version}-%{release}

%description    devel
The %{name}-devel package contains libraries and header 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 "cc -q64" or "gcc -maix64".
