[PD] Re: Mac OS X installer with library documentation

That's a good point which I forgot.  My main point is that we should  
try to set things up so that the Pd.app never needs to be modified, so  
that upgrades are just a matter of deleting one Pd.app and swapping in  
the new one.  (This applies to all platforms, of course, just not the  
.app part;).

In the MacOS X way, there are two mirrored locations for such  
application extensions: system (/Library/Pd) and user (~/Library/Pd).   
So on Windows we could have "C:\Program Files\Common\Pd" and  
"C:\Documents and Settings\username\...blah blah...\Pd".  On UNIX, the  
same idea "/usr/local/lib/pd" and "~/lib/pd", or something like that.
