19     //------------------------------------------------------------------------------------------------------------
20     //| fatal      | Fatal                      | Designates very severe error events that will presumably lead  |
21     //|            |                            | the application to abort.                                      |
22     //------------------------------------------------------------------------------------------------------------
23     //| error      | Fatal, Error               | Designates error events that might still allow the application |
24     //|            |                            | to continue running.                                           |

27     //------------------------------------------------------------------------------------------------------------
28     //| info       | Fatal, Error, Warn, Info   | Designates informational messages that highlight the progress  |

30     //------------------------------------------------------------------------------------------------------------
31     //| debug      | Fatal, Error, Info, Warn   | Designates fine-grained informational events that are most     |
32     //|            | Debug                      | useful to debug an application.                                |

34     //| trace      | All levels                 | Traces the code execution between methods, lines, etc.         |
