Best Python debugger

I don't use pdb often, but today, I needed one. I suspected that there should be a pdb module for emacs. Although GUD requires separate wrapper to PUD, there is a built-in module in Emacs. I just realized that GUD is a wrapper for another process instance. Not a big deal.
Create this file in somewhere PATHable and name it pdb.

exec python2.6 /usr/lib/python2.6/pdb.py $1 $2 $3 $4 $5 $6 $7 $8 $9

And then, you are good to go. Someone mentioned that backtracing does not work across modules. I didn't test that because his/her post was dated long time ago with emacs 21.
With pdb, 'C-x +' (balance-windows) will be very useful.
