This module implements a multi-process supervisor.

It takes a list of commands to execute and starts each one, and then monitors their execution. If one of the programs dies, the supervisor will restart it after start_delay seconds. If a program respawns during start_delay for start_retries times, the supervisor gives up and stops it indefinitely.

You can send SIGTERM to the supervisor process to kill all childs and exit.

You can also send SIGINT (Ctrl-C on your terminal) to restart the processes. If a second SIGINT is received and no child process is currently running, the supervisor will exit. This allows you to tap Ctrl-C twice in quick succession in a terminal window to terminate the supervisor and all child processes
