 /**
  * Object that to automatically load classes within a root directory.
- * 
- * An Autoloader instance can register itself to the SPL autoload stack.
+ * Simple example: all classes are located in the 'classes' directory.
+ * <code>
+ * $loader = new Autoloader('classes');
+ * $loader->load_class('FooBar');  // Includes file 'classes/foo_bar.php'
+ * </code>
+ * 
+ * An Autoloader instance can register itself to the SPL autoload stack, so
+ * that explicit 'include' statements for classes are not necessary anymore.
+ * Applied to the example above:
+ * <code>
+ * $loader = new Autoloader('classes');
+ * $loader->register();
+ * $foobar = new FooBar();  // File 'classes/foo_bar.php' is automatically included
+ * </code>
+ * 
+ * Namespaces are assumed to indicate subdirectories:
+ * <code=php>
+ * Autoloader::create('classes')->register();
+ * $bar = new Foo\Bar();      // Includes 'classes/foo/bar.php'
+ * $baz = new Foo\Bar\Baz();  // Includes 'classes/foo/bar/baz.php'
+ * </code>
+ * 
+ * Multiple autoloaders can be registered at the same time. Be sure to disable
+ * exceptions on the previously added loaders!
+ * <code>
+ * <code>
+ * File structure:
+ * classes/
+ *   | foo.php  // Contains class 'Foo'
+ * other_classes/
+ *   | bar.php  // Contains class 'Bar'
+ * </code>
+ * Autoloader::create('classes', false)->register();
+ * Autoloader::create('other_classes')->register();
+ * $foo = new Foo();  // Includes 'classes/foo.php'
+ * $bar = new Bar();  // Includes 'other_classes/bar.php', since 'classes/bar.php' does not exist
+ * $baz = new Baz();  // Throws an exception, since 'other_classes/baz.php' does not exist
+ * </code>
