I think this should be subject of a small How-To. Anyway...to register
a plugin index you have to call "context.registerClass(...)". Take
a look at PluginIndexes/__init__.py how Zopes indexes are
registered. Other indexes should do it in the same way.

The reason why PluginIndexes are installed as first product is that there
are some dependencies between PluginIndexes and other Zope Products.
Products are usually inialized in alphabetical order. But in this case
we made an exception.
