+A simple helper to assist with writing MCollective actions in PHP.
+
+Given an action as below:
+
+<pre>
+action "echo" do
+ validate :message, String
+
+ implemented_by "/tmp/echo.php"
+end
+</pre>
+
+The following PHP script will implement the echo action externally
+replying with _message_ and _timestamp_
+
+<pre>
+<?php
+ require("mcollective_action.php");
+
+ $mc = new MCollectiveAction();
+ $mc->message = $mc->data["message"];
+ $mc->timestamp = strftime("%c");
+ $mc->info("some text to info log on the server");
+?>
+</pre>
+
+Calling it with _mco rpc_ results in:
+
+<pre>
+$ mco rpc test echo message="hello world"
