Earlier this week, Jesse Alama brought up the topic of scheduling
cron jobs with koyo and we both agreed that it would be nice if koyo
had built-in support for that sort of thing. So, I wrote crontab,
a little library for parsing cron-style schedules and executing
code based on them. On top of that functionality, I've added a new
koyo/crontab module to koyo that integrates with the
component system.
