-  Logging conveniences for Bandit servers
-
-  Allows dynamically adding and altering the log level used to trace connections
-  within a Bandit server via the use of telemetry hooks. Should you wish
-  to do your own logging or tracking of these events, a complete list of the
-  telemetry events emitted by Bandit is described in the module documentation
-  for `Bandit.Telemetry`.
-
-  The logging included in this module is concerned specifically with protocol level events.
-  Should you wish to log lower level transport concerns, there are similar functions to these in
-  the `ThousandIsland.Logger` module. Corresponding telemetry events are described in the
-  module documentation for `ThousandIsland.Telemetry`.
