runsv supervises a single service. It runs and monitors the service defined in the directory.
The run script is executed and monitored. If it exits, runsv restarts it.
Optional finish script runs after service exits. Cleanup operations go here.
Optional log directory runs a logging service. Captures stdout/stderr.
Control interface via supervise directory. The sv command communicates here.
