Description:

Introspection for the ``logging`` logger tree in the Standard Library.

While you can write programs that call this package's ``tree()``
function and examine the hierarchy of logger objects that it finds
inside of the Standard Library ``logging`` module, the simplest use of
this package for debugging is to call ``printout()`` to print the
loggers, filters, and handlers that your application has configured::

>>> logging.getLogger('a')
>>> logging.getLogger('a.b').setLevel(logging.DEBUG)
>>> logging.getLogger('x.c')
>>> from logging_tree import printout
>>> printout()
""
Level WARNING
|
o<--"a"
| |
| o<--"a.b"
| Level DEBUG
|
o<--[x]
|
o<--"x.c"
