Logbook
-------
An awesome logging implementation that is fun to use.
Quickstart
``````````
::
from logbook import Logger
log = Logger('A Fancy Name')
log.warn('Logbook is too awesome for most applications')
log.error("Can't touch this")
Works for web apps too
``````````````````````
::
from logbook import MailHandler, Processor
mailhandler = MailHandler(from_addr='servererror@example.com',
recipients=['admin@example.com'],
level='ERROR', format_string=u'''\
