"""Define the menu contents, hotkeys, and event bindings. There is additional configuration information in the EditorWindow class (andsubclasses): the menus are created there based on the menu_specs (class)variable, and menus not created are silently skipped in the code here.  Thismakes it possible, for example, to define a Debug menu which is only present inthe PythonShell window, and a Format menu which is only present in the Editorwindows.
