Agents for Job Execution and Communication Tasks
================================================
Agents collect informations and transfer them e.g. to a loops server.
($Id$)
This package does not depend on zope or the other loops packages
but represents a standalone application.
But we need a reactor for working with Twisted; in order not to block
testing when running the reactor we use reactor.iterate() calls
wrapped in a ``tester`` object.
>>> from cybertools.agent.tests import tester
Master Agent
============
The agent uses Twisted's cooperative multitasking model.
This means that all calls to services (like crawler, transporter, ...)
return a deferred that must be supplied with a callback method (and in
most cases also an errback method).
>>> #from cybertools.agent.core.agent import Master
>>> #master = Master()
