[Pythonmac-SIG] A couple of universal binary questions

[Michael Glassford]

Is it possible to build a universal binary version of a Py2App/PyObjC 
based application that runs on pre-Tiger Macs? I assume this would 
require doing the build on a non-Intel Mac, since you generally have to 
build it on the earliest system version you want to run it on to get the 
right Foundation and AppKit. If so, could you point me to more 
information on how this is done?

What's the right way to detect within the application whether its 
running on an Intel or a PowerPC Mac? I can figure out a way on my own 
(such as looking at sys.byteorder), but I wonder if there's an 
"official" way.

Thanks,

Mike
