Michman installs Supervisor on your servers and uses it to manage your queues, schedules and daemons.
Daemons are used to keep long-running scripts and processes alive. For instance, you could have a custom backup script running. If the process exits - Supervisor will restart it automatically.
And you don't even have to read the documentation for Supervisor, because we apply sane default config and give you a simple UI to manage daemons on your servers.
