description         Compiler and libraries for the OCaml programming language
long_description    OCaml is an industrial strength programming language \
                    in the ML family, supporting functional, imperative \
                    and object-oriented styles.

# debug problems with these patches.

# bytecode-only build (arch=none) on those targets. The old native-ppc and
# 32-bit-darwin shared-library configure patches no longer apply and are not
