cpython/Demo/tkinter/guido/kill.py
Brett Cannon a23810f86a The commands module has been removed. The getoutput() and getstatusoutput()
functions have been added to the subprocess module.

The fixer for this still needs to be written and proper Py3K deprecation
warnings for the functions that didn't make the transition need to be done in
2.6.

This is all part of trying to close issue #2872.
