    "    * **WARNING**: An indication that something unexpected happened, and that user action may be required.\n",
    "    * **ERROR**: indicates a more serious issue where something failed but the task is continuing\n",
    "    * **CRITICAL**: A serious error, indicating that the program itself may be unable to continue running.\n",
