Configuration functions for the logging package for Python. The core package
is based on PEP 282 and comments thereto in comp.lang.python, and influenced
by Apache's log4j system.

To use, simply 'import logging' and log away!

Read the logging configuration from a ConfigParser-format file.
This can be called several times from an application, allowing an end user
the ability to select from various pre-canned configurations (if the
developer provides a mechanism to present the choices and load the chosen
configuration).

Convert values to an appropriate type. dicts, lists and tuples are
replaced by their converting alternatives. Strings are checked to
see if they have a conversion format and are converted if they do.

Start up a socket server on the specified port, and listen for new
configurations.
These will be sent as a file suitable for processing by fileConfig().
Returns a Thread object on which you can call start() to start the server,
and which you can join() when appropriate. To stop the server, call
stopListening().

Handler for a logging configuration request.
It expects a completely new logging configuration and uses fileConfig
to install it.

Handle a request.
Each request is expected to be a 4-byte length, packed using
struct.pack(">L", n), followed by the config file.
Uses fileConfig() to do the grunt work.
