 Welcome! This project will hopefully help you run scheduled and repeating functions in Swift! This is a very basic start to having a robust cron application in pure Swift. There is still a lot of work to be done. Pull requests are encouraged and welcomed... 😃
 
-### IMPORTANT NOTE FOR UBUNTU USERS
-Right now this library uses NSTimer and, thus #selector and needs the objective-c runtime, so it only works on macOS. I am looking into other ways to accomplish this, but until then you're stuck with macOS.

 Everything should go in the order it is in the example. You may also import functions from another Framework or write your own inside new files in your project. Cron will accept any valid functions that have no return and no parameters.

-while shouldKeepRunning && theRL.run(mode: .defaultRunLoopMode, before: .distantFuture) {  }

-
-This **MUST** be at the **END** of main.swift, because it keeps the application running. Without this line at the end, the application would simply terminate on launch.

 Hopefully there is more to come. For now, please enjoy.
