%description
A free open source portable number theoretic multiple-precision integer
library 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".
