Summary: logging module documentation

Initial Comment:
I believe the logging module documentation needs to give an 
example of how to simply log to a file. The following example snippet 
could be appropriate: 
 
import logging 
logger = logging.getLogger('myapp') 
hdlr = FileHandler('/var/myapp/debug.log') 
hdlr.setFormatter(Formatter('%(asctime)s %(level)s %(message)s')) 
logger.addHandler(hdlr) 
logger.setLevel(DEBUG)

Please consider adding a simpler interface for people who just 
want to log to a file: 
 
  import logging 
  logger = logging.open('/var/log/myapp.log') 
 
which does the equivalent of: 
 
  import logging 
  logger = logging.getLogger('<default>') 
  hdlr = logging.FileHandler('/var/log/myapp.log') 
  formatter = logging.Formatter('%(asctime)s %(levelname)s 
%(message)s') 
  hdlr.setFormatter(formatter) 
  logger.addHandler(hdlr) 
  logger.setLevel(logging.INFO) 
 
which is what I expect most users will want when they first 
see this module. If they then want to mess around with 
additional handers, or different formatting or whatever, then 
they can read the reference doc. 
 
Please make the simplest use-case much simpler!

I would also like to see a more thorough set of introductory
examples.  The second page of the unittest documentation
could serve as a model -- it attempts to cover the 90% of
what you need to know in a single page of examples.   As it
stands now, the documentation for the logging module is
formidable.  Those wanting to take advantage of the module
face a steep learning curve from rather heavyweight
documentation -- it's complexity exceeds that of almost all
modules except for the email and xml packages.

Assigning to Vinay Sajip to work with Anthony to improve the
docs.

Why was this closed? nnorwitz's doc fixes, as seen in CVS or 
http://www.python.org/dev/doc/devel/lib/module-logging.html
have no examples section.  

Running the current logging module docs past a number of 
python coders here produced a consistent "what the heck?"
response - the opening introduction provides no indications of
how to use the package. 
This is a problem for me, right now, so I'm re-opening and
assigning to myself to fix.

I just updated the logging documentation.  Could you please
review for accuracy and completeness?
