option: alternate-url
Alternate URL. If supported by Buildout, it is used as fallback if the main
URL (`url` option) fails at HTTP level.
Useful when a version of a resource can only be downloaded with a temporary
URL as long as it's the last version, and this version is then moved to a
permanent place when a newer version is released: `url` shall be the final URL
and `alternate-url` the temporary one.

An MD5 checksum can be specified to check the downloaded file, like for the
``download`` recipe. However, if unset, updating the part does nothing.

See the ``download`` recipe.
