title: What kind of artifacts do pip repos use?
body: <p>I understand the difference between a python module and package, but I cannot find a clear answer that tells me what type of artifact the pip repos truly manage in the end.</p>
  <p>For example, if I write a big python application like QT, what artifact do I need to build inorder to upload it to a pip repository server? Is it just a zip of the folder, the raw folder (unlikely and I hope not) or a special run-able python compressed format analogous to how java uses WAR files.</p>
