jjb/ruby-clock: A ruby job scheduler which runs jobs each in their own thread in a persistent process.

ruby-clock is a job scheduler, known by heroku as a clock process. In many cases it can replace the use of cron.Why another ruby scheduler project? See this feature matrix of the space. Feel free to leave a comment with suggestions for changes or additions.This gem is very small with very few lines of code. For all its scheduling capabilities, it relies on the venerable rufus-scheduler. rufus-scheduler does not aim to be a standalone process or a cron replacement, ruby-clock does.Jobs are all run in their own parallel threads within the same process.
