+	<p>The <c>start_disabled</c> command operates on a service
+	regardless of if it's enabled/disabled or started/stopped.  It
+	does this by first enabling it (regardless of if it' enabled
+	or not), then starting it (if it's not already started) and
+	then disabling it. The result will be a disabled but started
+	service, regardless of it's earlier state. This is useful for
+	starting services temporarily during a release upgrade. The
+	difference between using <c>start_disabled</c> and the
+	sequence <c>enable</c>, <c>start</c> and <c>disable</c> is
+	that all other <c>erlsrv</c> commands are locked out during
+	the sequence of operations in <c>start_disable</c>, making the
+	operation atomic from an <c>erlsrv</c> user's point of
+	view.</p>
