	"@brief A control which adds several reactions to other GUIs via callbacks.\n\n"

	"GuiScriptNotifyCtrl does not exist to render anything. When parented or made a child of "
	"other controls, you can toggle flags on or off to make use of its specialized callbacks. "
	"Normally these callbacks are used as utility functions by the GUI Editor, or other container "
	"classes. However, for very fancy GUI work where controls interact with each other "
	"constantly, this is a handy utility to make use of.\n\n "
