  Twisted's log module is used to publish certain kinds of information to any observer who cares to listen for it.  This file documents all of the "channels" used in Quotient (this includes atop and nevow).

atop
----
  db_txn
	with a value of "commit" whenever a bsddb transaction is commited
	with a value of "abort" whenever a bsddb transaction is aborted

  db_get
	always with a value of None.  This is called when an object is unpickled
	from the database.  Several other keys are associated with this message:

	path, with the item path (a tuple of integers) to the item being loaded
	item, with the actual object which was loaded
	pickle, with the string from which the pickle was loaded

  db_put
	always with a value of None.  This is called when an object is pickled
	into the database.  The same keys are available as those used by db_get.

  db_lock
	with a value of the string key of the item being locked.  path and item,
	with the same values as in db_get, are also available.

  db_cache
	with a value of "hit" whenever the memory cache is hit instead of the
	database itself

  login
	with a value of None for unauthorized logins
	with a value of the username who logged in for authorized logins

	in either case, the interface and mind keys are both available.

nevow
-----

  http_render
	with a value of None.  A uri key is also present with this message, the value
	of which is the uri being rendered.

quotient
--------

  storage
	with a value of "used" whenever non-database disk space is allocated for a user.
	type, amount, and avatar keys are also available.
