// A template HUD script for Corrade that reads a configuration notecard
// and then feeds that configuration to various other components of the HUD
// that request the configuration. Additionally, this HUD is programmed to
// "fold" and "unfold" depending on whether Corrade is online or not. For
// more information on the Corrade scripted agent please see the URL:
