 Here we first create an instance of OC_VCategories and tell it to store categories identified by ``contact`` type. Then we fetch all the contacts and create and array holding arrays of id/carddata [1]_ pairs. The OC_VCategories object is then told to scan all the vCards ``CATEGORIES`` property and save the result when done. If it finds any categories it doesn't know already, they will be added to the database (category names are NOT case-sensitive). Additionally it will create relations between the category and the contact object to be used by the contacts app. The ``rescan`` method also takes a third boolean argument ``reset`` which will purge any categories and relations for the current user.

 For acting on user input the following methods, which should be mostly self-explanatory, are available:
 
-.. code-block:: php

+   :param string $names: deletes the categories in the array `$names` and any object/category/user relations saved.
+   :param array $objects: If `$objects` is not null it is assumed to be an array of id/data pairs passed by reference.
+   :returns: the integer id of the new category or **false** if it already exists.

+   The data is parsed into an OC_VObject and if found the categories will be removed from the CATEGORIES property and the OC_VObject will be serialized back to a string again. It is up to the app to store the data afterwards.
