For a general Python package to be picked up, you would need to add a regular ZCML slug into the etc/package-includes directory of your instance. If your package is a namespace package in the 'Products' namespace, then it will be picked up automatically, once added to the PYTHONPATH. This is triggered by the five:loadProducts and five:loadProductsOverrides directives in your instances site.zcml. The code for those directives is either in Products.Five or OFS depending on which version of Zope2 you use.

If your package is a namespace package in the 'Products' namespace, then it will be picked up automatically, once added to the PYTHONPATH. In essence: If your egg is in the Products namespace you don't need to do anything after adding it e.g. to the list of eggs for a Zope instance in your buildout.cfg. The product will be recognized, installed, and any configure.zcml in the root picked up automatically. That's one reason I stick to that namespace for anything that is indeed a Zope 2 Product. jens -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.8 (Darwin) iEYEARECAAYFAkxZKzQACgkQRAx5nvEhZLK7TgCeI2n6Y+xjagXyPZHeNuEII2V3 xMUAoIJHoErxjlAjZRWYPME8tEPM1S2O =IYFz -END PGP SIGNATURE- ___ Zope-Dev maillist - Zope-Dev@zope.org https://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - https://mail.zope.org/mailman/listinfo/zope-announce https://mail.zope.org/mailman/listinfo/zope )

Yes. Eggified products behave in the same way as code dumped into one of the products directories. If you have a package, which isn't in the Products namespace and still want its initialize to be called, you need to add some bits to your configure.zcml: five:registerPackage package=. initialize=.initialize / Yeah, but it's setuptools namespace packages magic that makes sure __path__, which the old Zope 2 code iterates over, is set up correctly, right?
