-#  This script will pull tests to complete from the Beanstalk Queue,
-# where they will be found in JSON form, and executes them.
+# NAME
+#  custodian-dequeue - Pull network tests from a queue and execute them in series.
 #
-# Steve
-# --
+# SYNOPSIS
+#  custodian-dequeue  [ -h | --help ]
+#                     [ -m | --manual]
+#                     [      --server 1.2.3.4:123 ]
+#                     [ -s | --single ]
+#                     [ -v | --verbose ]
+#                     [ -f | --flush ]
+#
+# OPTIONS
+#
+#  -h, --help          Show a help message, and exit.
+#
+#  -m, --manual        Show this manual, and exit.
+#
+#  -f, --flush         Flush the queue, removing all jobs.
+#
+#  -s, --single        Run a single test and exit.  Don't poll the queue for more.

+#
+# ABOUT
+#
+#  This tool is designed to pull JSON-encoded network/protocol-tests from
+# a beanstalkd server and execute them, in series.
+#
+#  The tests are created, via custodian-enqueue, by parsing a configuration
+# file largely compatible with that used for our obsolete sentinel tool.
+#
+#  The results of the testing will be sent to a mauvealert server.
