/**
-* Simple filesystem browser that can be used to generated menu (3) hashes.
+* Simple filesystem browser that can be used to generated menu (3) hashes based on
+the directory structure.
*
-* Together with menu (3) you can use this browser to generate simple
-* fusebox like systems.
+* Together with menu (3) and the (userland) cache you can use this
+* browser to generate simple fusebox like applications / content systems.
*
+* Let the menubrowser scan your document root and generate a menu (3) structure
+* hash which maps the directory structure, pass it to menu's setMethod() and
+optionally
+* wrap the cache around all this to save script runs. If you do so, it looks
+* like this:
+*
+* // document root directory
+* define("DOC_ROOT", "/home/server/www.example.com/");
+*
+* // instantiate the menubrowser
+* $browser = new menubrowser(DOC_ROOT);
+*
+* // instantiate menu (3)
+* $menu = new menu($browser->getMenu());
+*
+* // output the sitemap
+* $menu->show("sitemap");
+*
+* Now, use e.g. simple XML files to store your content and additional menu
+informations
+* (title!). Subclass exploreFile() depending on your file format.
