+ // The bitmasked value choices are as follows:
+ // a) unset: In this case (the default) JSBSim would only print
+ // out the normally expected messages, essentially echoing
+ // the config files as they are read. If the environment
+ // variable is not set, debug_lvl is set to 1 internally
+ // b) 0: This requests JSBSim not to output any messages
+ // whatsoever.
+ // c) 1: This value explicity requests the normal JSBSim
+ // startup messages
+ // d) 2: This value asks for a message to be printed out when
+ // a class is instantiated
+ // e) 4: When this value is set, a message is displayed when a
+ // FGModel object executes its Run() method
+ // f) 8: When this value is set, various runtime state variables
+ // are printed out periodically
+ // g) 16: When set various parameters are sanity checked and
+ // a message is printed out when they go out of bounds.
