For an application actually embedding Python, you don't ever use the 
executable, just the framework.  Bundlebuilder2, as-is, does not embed 
Python, because it does not have an executable stub (just scripts).  
PyMacApp and the PyObjC Xcode template (they are indistinguishable) 
does.

That's probably a bad idea.

There are two problems you can have.  You can't link to the framework 
properly (boom! link error), or the Python code doesn't work.  My 
executable stub handles both of these situations elegantly and anyone 
who cares should take a look at it.  If your software is not Python 
based but uses Python (I believe Glenn is in this camp), then you can 
just as easily rip code out of my executable stub and use it in your 
own program.  I don't care, and the license permits.
