+# Port control script for Digital Loggers Inc. Web Power Switch II and III
+#
+# Written by: Grant Likely <grant.likely@secretlab.ca>
+# Copyright 2010 Secret Lab Technologies Ltd.
+#
+# Usage: dli-pscontrol.sh <admin:passwd@host> <port> {on|off|cycle}
+#
+# <port> is in the range 1..8.
+# 'cycle' will turn a port off and on with a 1 second delay.
+#
+# The Web Power Switch uses a simple http request protocol for controlling
+# the port state.  The action simply gets encoded into the url in the form:
+#
+#   http://<user>:<passwd>@<host[:port]>/outlet?<port-number>={ON|OFF|CCW}
+#
+# ON and OFF are self explanatory.
+# CCW means cycle power, but only has effect when the port is already on.
+#
+# The protocol is simple enough that wget is sufficient to control ports.
