PyPI usage statistics, the zc.buildout effect

It is interesting to look at the usage statistics at PyPI: [][]

Besides the front page, the most visited pages are in order (same thing in April):
- zc.buildout - setuptools - zc.recipe.egg - plone.recipe.zope2instance - plone.recipe.distros - python-openid - elementtree - plone.recipe.zope2install

Then the packages in the top 60 are mainly zope eggs. This corresponds to the sequence done by a Plone or Zope being build in a buildout.

If you take a closer look at [][], the next top hits corresponds to zope.* then plone.* packages.
