+#!/bin/bash

+# This script is similar to minion but will do a few additional things:
+# - PHP process is run in the background
+# - PHP process is monitored and restarted if it exits for any reason
+# - Added handlers for SUGHUP, SIGINT, and SIGTERM
+#
+# This is meant for long running minion tasks (like background workers).
+# Shutting down the minion tasks is done by sending a SIGINT or SIGTERM signal
+# to this miniond process. You can also restart the minion task by sending a
+# SUGHUP signal to this process. It's useful to restart all your workers when
+# deploying new code so that the workers reload their code as well.
+# You cannot use this script for tasks that require user input because of the
+# PHP process running in the background.
+#
+# Usage: ./miniond [task:name] [--option1=optval1 --option2=optval2]
+#
+# And so on.
