[Twisted-Python] Asynqueue 101 (Help)

Hi, I want to develop a server that has a dispatcher and worker processes. Asynqueue seems to be a perfect choice for my intention. However, I couldn't understand what I should do first and next. The workers will be processes and tasks will be queued and assigned to the child processes. There are many classes but I couldn't understand their interaction. For example what is the difference between a job and a task. How will I use TaskQueue with child processes or process workers. I need some examples, asynqueue has some test codes but they don't give enough clue to me. I need the general idea and the use of asynqueue. Thanks in advance.
