Syn: custom_url_rewrite_inbound(&$result, $path, $path_language)

1. custom_url_rewrite_inbound is not a hook, it's a function.
2. You can add to settings.php to alter incoming requests so they map to a Drupal path.
3. This function is called before modules are loaded and the menu system is initialized and it changes $_GET['q'].

This function should change the value of $result by reference.

Parameters:

$result: The Drupal path based on the database. If there is no match in the database it'll be the same as $path.

$path: The path to be rewritten.

$path_language: An optional language code to rewrite the path into.
