quick question: If I want to whitelist everything but a few packages, is that possible with devpi indexes and if so what is the syntax?
E.g. i'd expect:
`mirror_whitelist=['*', '!somepack', '!mypackage']`
would whitelist things like `pip` and `setuptools` but not the two explicitly forbidden packages named somepack and mypackage.
Cheers and thx, Christoph
