python naming convention for plugins, i.e. non-top-level packages
<p>I'm wondering if there is naming convention for non-top-level python packages, i.e. so called plugins or extensions. According to PyPI the plugins, mostly, named with dash(-) or dot(.)</p>

<p>e.g.:
most django plugins named with dash while plone/zope and many others prefer the dot, WTF? :)</p>

<p>Thanks!</p>
