%description
zn_poly is a C library for polynomial arithmetic in Z/nZ[x], where n is
any modulus that fits into an unsigned long.

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

%description devel
zn_poly is a C library for polynomial arithmetic in Z/nZ[x], where n is
any modulus that fits into an unsigned long.

This package contains the development files.

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".
