    // @description
    // Using the /denizen debug command interfaces with Denizen's dBugger to allow control
    // over debug messages.
    //
    // To enable debugging mode, simply type '/denizen debug'. While debug is enabled, all debuggable
    // scripts, and any invoked actions, will output information to the console as they are executed.
    // By default, all scripts are debuggable while the dBugger is enabled. To disable a script
    // specifically from debugging, simply add the 'debug:' node with a value of 'false' to your script
    // container. This is typically used to silence particularly spammy scripts. Any kind of script
    // container can be silenced using this method.
    //
    // To stop debugging, simply type the '/denizen debug' command again. This must be used without
    // any additional options. A message will be sent to show the current status of the dBugger.
    // Note: While your server is in 'live production mode', the dBugger should be disabled as your
    // server will run slower while outputting debug information.
    //
    // There are also several options to further help debugging. To use an option, simply attach them
    // to the /denizen debug command. One option, or multiple options can be used. For example: /denizen debug -ce
    //
    // '-c' enables/disables color. This is sometimes useful when debugging with a non-color console.
    // '-r' enables recording mode. See also: /denizen submit command
    // '-e' enables/disables world event timings. While enabled, the dBugger will show all triggered events.
    // '-s' enables/disables stacktraces generated by Denizen. We might ask you to enable this when problems arise.
    // '-b' enables/disables the ScriptBuilder debug. When enabled, Denizen will show info on script and argument creation.
    //      Warning: Can be spammy.
    // '-n' enables/disables debug trimming. When enabled, messages longer than 512 characters will be 'snipped'.
    //
    // The dBugger also allows the targeting of specific scripts by using the '--filter script_name' argument. For
    // example: /denizen debug --filter 'my script|my other script' will instruct the dBugger to only debug the
    // scripts named 'my script' and 'my other script'. Multiple scripts should be separated by a pipe character (|).
    // The --filter argument is cumulative, that is, scripts specified are added to the filter. To add more scripts,
    // simply use the command again. To clear the filter, use the -x option. Example: /denizen debug -x
    //
