 * Definitions used for IPC communications with SystemStarter.
 * SystemStarter listens on a CFMessagePort with the name defined by
 * kSystemStarterMessagePort.  The messageID of each message should
 * be set to the kIPCProtocolVersion constant.  The contents of each
 * message should be an XML plist containing a dictionary using
 * the keys defined in this file.
