//
// Interface for CON scripts to get descriptions for actions
// This code can query the 64 original game functions by index.
//
// This is mostly an ill-advised hackery to change menu texts. It no longer
// changes the menu but gets used when scripts try to write
// key related messages. Ion Fury uses this and is one of the reasons
// why that game is by all accounts not localizable.
//
// Important note: The list of actions may not be altered. If some of these
// commands get refactored, the string below needs to be changed to match
// the new command.
