 Loading this Helper
 ===================
@@ -16,64 +21,63 @@ This helper is loaded using the following code
 
 	$this->load->helper('directory');
 
+Available Functions
+===================
+
 The following functions are available:
 
-directory_map()
-===============
 
-This function reads the directory path specified in the first parameter
-and builds an array representation of it and all its contained files.
-	
-.. php:method:: directory_map($source_dir[, $directory_depth = 0[, $hidden = FALSE]])
+.. function:: directory_map($source_dir[, $directory_depth = 0[, $hidden = FALSE]])
 
 	:param string	$source_dir: path to the ource directory
 	:param integer	$directory_depth: depth of directories to traverse (0 =
 		fully recursive, 1 = current dir, etc)
 	:param boolean	$hidden: whether to include hidden directories
-	
-Examples::
-
-	$map = directory_map('./mydirectory/');
-
-.. note:: Paths are almost always relative to your main index.php file.
-
-
-Sub-folders contained within the directory will be mapped as well. If
-you wish to control the recursion depth, you can do so using the second
-parameter (integer). A depth of 1 will only map the top level directory::
-
-	$map = directory_map('./mydirectory/', 1);
-
-By default, hidden files will not be included in the returned array. To
-override this behavior, you may set a third parameter to true (boolean)::
-
-	$map = directory_map('./mydirectory/', FALSE, TRUE);
-
-Each folder name will be an array index, while its contained files will
-be numerically indexed. Here is an example of a typical array::
-
-	Array (    
-		[libraries] => Array    
-			(        
-				[0] => benchmark.html        
-				[1] => config.html
