Complies fully with the standard cron format. Also includes the following shorthand formats which cron also supports: @yearly, @monthly, @weekly, @daily, @hourly. Note that this parser will fail if there is extraneous input. This is to prevent things like extra fields. If you want a more lax parser, use (", which is fine with extra input.(Same as '' but does not fail on extraneous input.)eParses a full crontab file, omitting comments and including environment variable sets (e.g FOO=BAR).*iParses an individual crontab line, which is either a scheduled command or an environmental variable set.'()*LMNOPQRSTUVWXYZ['()*'()*'()*LMNOPQRSTUVWXYZ[=Monad stack for scheduling jobs to be executed by cron rules.(c) Andrew Rademacher 2014MIT.Andrew Rademacher <andrewrademacher@gmail.com>portableNone-CN7ÿUSchedule all of the jobs to run at appropriate intervals. Each job that is launched gets a scheduling thread to itself. Each time a scheduling thread launches a job, the job is forked onto a new thread. This means that if a job throws an excpetion in IO, its thread will be killed, but it will continue to be scheduled in the future.\½Start a job-runner thread that runs a job at appropriate intervals.
