I'll try once more, before giving up.  You want to put something at the 
head of target.py that has some effect on the running of that script.

Which is it you want,  "output is swapped case"?

Or do you want the equivalent of putting swapcase() after each literal 
string?

You can't have it both ways, since swapping the case of literals does 
not affect all output.  And it affects things that are not output.
