Runners

The Meteor tool process would run multiple big "parts" that should be managed: started, stopped, restarted, monitored for crashes, etc.

The interface that Meteor tool uses is called a "runner".

Some of the runners run sub-processes. The main runner is called run-all, it has sub-runners such as run-app, run-mongo and run-proxy. Other runners are used for different CLI commands.
