[Distutils] Buildout and non-pypi hosted packages

[Tom Aratyn]

Hello,

I work for an organization which would like to use buildout but we're
hitting a problem with buildout and pyrtf (which is not hosted in the
cheeseshop but is available off a url form sourceforge). Pip has no
problem with this but I'm not sure how to get buildout to understand
it.

We're listing all our dependencies using install_requires. Is there a
way to do this?

Cheers,

Tom
