title: How can I use conda skeleton with packages that are not uploaded to pypi?
body: <p>I am trying to use conda skeleton to build conda packages for some python packages that were not uploaded to pypi.</p>
  
  <p>I cannot upload them to pypi and I don't want to have to deploy a local pypi server. They are stored on the local machine, being the results of a recent build and now I want to also build their conda packages.</p>
  
  <p>How can I do this? I tried various options for <code>--pypi-url</code> but I get a <code>OSError: unsupported XML-RPC protocol</code> which tells me that skeleton expects a real PYPI and that it cannot really deal with local repositories. PIP can work with local directories without problems.</p>
  
  <p>What would be the way to overcome this?</p>
