you CAN LOSE FILES THIS WAY!!!**. The smart move here is to use
test mode and make sure your proposed renaming isn't going to
require deeply recursive backups.
 
- The argument ``-r=`` is always ignored because it means "change
the empty string into the empty string". It might be tempting
to try this to get rid of characters via a target, but it won't
work::
 
tren.py -T -1 -r= foo- # Nope - have to do it explicitly
 
tren.py -T -1 -r-= foo- # Yup
 
 
- Save the output from your **tren** runs in logs. That way, if you
have to unwind a renaming gone bad, you'll have a record of what was
done.
