Is there anything like Satis from PHP for Python? I've tried some tools for "private pypi's" respectively private package indexes like devpi or pyshop. I want to mirror some packages which are also needed offline, but I don't want to mirror the whole pypi (more like a caching proxy). And I want to upload privately developed packages. Also it would be really useful if it automatically caches the dependencies of my uploaded packages or if I can give it a file containing all needed packages (like satis build) with the source (e.g. pypi, vcs/svn) and it caches / adds them to the index.
I'm searching for a option to make a private package index but devpi has not all the features I need.
