""" wicd - wireless connection daemon frontend implementation
This module implements a usermode frontend for wicd. It updates connection
information, provides an (optional) tray icon, and allows for launching of
the wicd GUI and Wired Profile Chooser.
class TrayIcon() -- Parent class of TrayIconGUI and IconConnectionInfo.
class TrayConnectionInfo() -- Child class of TrayIcon which provides
and updates connection status.
class TrayIconGUI() -- Child class of TrayIcon which implements the tray.
icon itself. Parent class of StatusTrayIconGUI and EggTrayIconGUI.
class StatusTrayIconGUI() -- Implements the tray icon using a
gtk.StatusIcon.
class EggTrayIconGUI() -- Implements the tray icon using egg.trayicon.
def usage() -- Prints usage information.
def main() -- Runs the wicd frontend main loop.
