Taskforest is a simple but expressive open-source job scheduler that allows you to chain jobs/tasks and create time dependencies. It uses text config files to specify task dependencies.

With the TaskForest Job Scheduler you can:

• schedule jobs to run at predetermined times,
• have jobs be dependent on each other
• rerun failed jobs
• mark jobs as succeeded or failed
• check the status of all jobs scheduled to run today
• interact with the included web service using your own client code
• interact with the included web server using your default browser
• express the relationships between jobs using a simple text-based format (a big advantage if you like using 'grep')
• browse job log files using the included web server
