Perhaps there is a more 'compact' way to do this, but it occurs to me that each
code segment of your app is also a 'CODE' resource in the compiled app.  SInce
you know how to change the resources, swap in the new CODE resources as well. 
If you simply made changes to one code segment, then you'll only need replace
that one CODE segement.

Sorry, I think I spoke too fast.  It occurs to me now that perhaps the main
CODE segment will differ as well.  I'm just stabbing though, I'm still pretty
much in the dark as to how programs are compiled and then loaded by the Mac.
