+
+    Comprehensively adds a new logging level to the `logging` module and the
+    currently configured logging class.
+
+    `levelName` becomes an attribute of the `logging` module with the value
+    `levelNum`. `methodName` becomes a convenience method for both `logging`
+    itself and the class returned by `logging.getLoggerClass()` (usually just
+    `logging.Logger`). If `methodName` is not specified, `levelName.lower()` is
+    used.
+
+    To avoid accidental clobberings of existing attributes, this method will
+    raise an `AttributeError` if the level name is already an attribute of the
+    `logging` module or if the method name is already present
+
+    Example
+    -------
+    >>> addLoggingLevel('TRACE', logging.DEBUG - 5)
+    >>> logging.getLogger(__name__).setLevel("TRACE")
+    >>> logging.getLogger(__name__).trace('that worked')
+    >>> logging.trace('so did this')
+    >>> logging.TRACE
+    5
