supervise monitors a service. It starts the service and restarts the
service if it dies. Setting up a new service is easy: all supervise
needs is a directory with a run script that runs the service.

multilog saves error messages to one or more logs. It optionally timestamps
each line and, for each log, includes or excludes lines matching specified
patterns. It automatically rotates logs to limit the amount of disk space
used. If the disk fills up, it pauses and tries again, without losing any
data.
