[Pythonmac-SIG] py2app on Tiger

[Charles Hartman]

Thanks, that clarifies it. Since I'm not -- at least in my main current 
project -- compiling any extensions, just using off-the-shelf Python 
2.3 and wxPython, it sounds as though my life shouldn't get *too* much 
more compicated too soon. I'm pretty sure my fairly straightforward 
code isn't using anything in 2.3 that will turn out not to work in 2.4. 
(Famous last words?)

Probably like a lot of people, I don't care much about supporting 
versions of the OS that "nobody" (???) is using. Not only don't I have 
an OS9 version of my application, I don't worry about the absence of a 
10.2 version, because "people" -- which means everyone I know in the 
audience for my weird app -- will have upgraded to 10.3 by now. That 
implies that, from now on, I'll need to keep one (1) bootable partition 
around with the previous x in 10.x, but no more. I'm counting on the 
herd instinct, here.
