# Source Generated with Decompyle++ # File: in.pyc (Python 2.4) """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.
