================
- Use zc.buildout's download API. As this allows MD5 checking, added the
md5sum and patch-md5sum options.
- Added options for changing the name of the configure script and
overriding the ``--prefix`` parameter.
- Moved the core "configure; make; make install" command sequence to a
method that can be overridden in other recipes, to support packages
whose installation process is slightly different.
