Project: Job Manager

The Job Manager component is responsible for creating and managing jobs

within the system.

This includes tracking the state of "active" jobs and the retrieval of

stored jobs. Job Manager can be thought of as having several roles,

including a registry of jobs, the scheduling jobs, and providing status of

jobs in the system. Additionally, the Job Manager connects I/O filters

with successive Job Stream interfaces before passing the resultant Job

Stream to the Job.
