Agreed. I searched through matplotlib and pytz, and found that you  
can add a straightforward import of pytz.zoneinfo.UTC rather than  
going through a loader function. I will submit as a patch to the  
matplotlib developers. I suggest leaving the line in the recipe for a  
while at least.

Agreed, although with the latest version of py2app working out of the  
box with the recipes, I'll probably let it slide.

I spent a bit more time looking at matplotlib, and realised I just  
need to include the data files (fonts, rc, icons) directory in the  
Resources dir in the app. When I did this manually, it worked fine,  
since there is code to detect frozen status in the initialisation,  
and it searches the Resources dir.

However, I can't figure out how to copy resources in the recipe. It  
seems in recipes, you can return in the dict: packages, flatpackages,  
filters, loader_files, and prescripts. Could you enlighten me on the  
use of each of these?
