Hi, Cool lib, but one minor correction: quartzite is backed by Quartz, which features a number of different scheduling mechanisms, including a unix-like CronExpression, but it's not a traditional crontab spec. In particular, it has an additional seconds field and a pretty handy "increment" operator. See http://www.quartz-scheduler.org/api/2.1.5/org/quartz/CronExpression.html for details.
