+Zotlabs/Module
+==============
+
+
+This directory contains controller modules for handling web requests. The
+lowercase class name indicates the head of the URL path which this module
+handles. There are other methods of attaching (routing) URL paths to
+controllers, but this is the primary method used in this project.
+
+Module controllers MUST reside in this directory and namespace to be
+autoloaded (unless other specific routing methods are employed). They
+typically use and extend the class definition in Zotlabs/Web/Controller 
+as a template. 
+
+Template:
+
+	<?php
+
+	namespace Zotlabs\Web;
+
+
+	class Controller {
+
+		function init() {}
+		function post() {}
+		function get() {}
+
+	}
+
+
+Typical Module declaration for the '/foo' URL route:
+
+
+	<?php
+	namespace Zotlabs\Module;
+
+	class Foo extends \Zotlabs\Web\Controller {
+
+		function init() {
+			// init() handler goes here
+		}
+
+		function post() {
+			// post handler goes here
+		}
+
+		function get() {
+			return 'Hello world.' . EOL;
+		}
+
+	}
+
+This model provides callbacks for public functions named init(), post(), 
+and get(). init() is always called. post() is called if $_POST variables
+are present, and get() is called if none of the prior functions terminated
+the handler. The get() method typically retuns a string which represents 
+the contents of the content region of the resulting page. Modules which emit 
+json, xml or other machine-readable formats typically emit their contents
+inside the init() function and call 'killme()' to terminate the Module. 
+
+Modules are passed the URL path as argc,argv arguments. For a path such as
+
+	https://mysite.something/foo/bar/baz
+
+The app will typically invoke the Module class 'Foo' and pass it 
+
+	$x = argc(); // $x = 3
+
+	$x = argv(0); // $x = 'foo'
+	$x = argv(1); // $x = 'bar'
+	$x = argv(2); // $x = 'baz'
+
+These are handled in a similar fashion to their counterparts in the Unix shell
+or C/C++ languages. Do not confuse the argc(),argv() functions with the
+global variables $argc,$argv which are passed to command line programs. These 
+are handled separately by command line and Zotlabs/Daemon class functions.
