Is it possible to upload multiple versions of the same package to pypiserver?
<p>Say you have two different versions of the same package and want to upload them to <code>pypiserver</code> and have clients install the version they want via <code>pip</code>. Is this possible?</p>

<p>Yes it is possible.</p>

<p>You just upload package twice setting different version (e.g. first <code>0.1</code> and second <code>0.2</code>) in <code>setup.py</code> of your package.</p>

<p>Here is instruction how to upload:

<pre><code>pip install 'package_name==0.1'
</code></pre>
