title: cron scheduler with jobs dependency
body: <p>Our project has some distributed daily jobs which run in "crontab" and there are some dependencies between them. And we want job schedule is independent with our project(it seems like using Quartz should change current code). Does there any open source software provides functions like web-based cron management and jobs dependency?</p>
