You haven't missed anything, the documentation for PyObjC2 is not  
online yet due to lack of time on part.

I still use py2app. The Xcode templates are supported by Apple and are  
the best way to integrate with Xcode at the moment. py2app allows you  
to build applications without having Xcode installed.

The AutoBaseClass stuff is deprecated in PyObjC 2, I haven't  
eradicated it from all examples yet.  The main reasons for deprecation  
are that (1) it it no longer needed given Xcode/IB's support for  
PyObjC code and (2) the ".xib" files in Xcode3 use a completely new  
file format that the AutoBaseClass code doesn't grok.

If you're new to PyObjC but are confortable with Xcode I'd use the  
Xcode templates.
