DESCRIPTION

The svd command is a supervisor daemon for App::Sv.

It reads a list of commands to execute from a YAML config file and starts each one, and then monitors their execution. If one of the program dies, the supervisor will restart it after a preset delay.

You can restart the supervised process with Ctrl-C. If you hit Ctrl-C again before the supervised process restart, the supervisor will exit. This allows you to use one tap of Ctrl-C to restart, and a double tap to exit.
