-"""Extension to execute code outside the Python shell window.
-
-This adds the following commands:
-
-- Check module does a full syntax check of the current module.
- It also runs the tabnanny to catch any inconsistent tabs.
-
-- Run module executes the module's code in the __main__ namespace. The window
- must have been saved previously. The module is added to sys.modules, and is
- also added to the __main__ namespace.
-
-XXX GvR Redesign this interface (yet again) as follows:
-
-- Present a dialog box for ``Run Module''
-
-- Allow specify command line arguments in the dialog box
