34 :			** character that is to replace blanks in names that form the URL.
35 :			** You can vary this, although the only sensible choices seem to be
36 :			** underscore or hyphen (_ or -).
37 :			**
38 :			** The arrays $this->custom_code and $this->custom_name must be kept exactly
39 :			** in step with each other. $this->custom_code is a list of the components
40 :			** that are to be handled by ReMOSef.
41 :			**
42 :			** The array $this->custom_name is the alternative name that will be used
43 :			** in the optimised URL to identify the component and can be whatever
44 :			** you please so long as it is unique and legal for a URL. Apart from
45 :			** using the custom name for the component, ReMOSef will do no further
46 :			** translation of the URL than is done by the standard Mambo SEF - UNLESS
47 :			** there is a sef_ext.php file installed for that component. The
48 :			** exception to this is ReMOSitory - the optimisation code for Remository
49 :			** is integrated in ReMOSef. For other components, if a sef_ext.php is
50 :			** present, it will be invoked by ReMOSef.
51 :			**
52 :			** The array $remosef_content_task is capable of translating the tasks
53 :			** understood by the Mambo content component. Please DO NOT CHANGE what
54 :			** is to the left of the equals sign. When putting different values on
55 :			** the right hand side, remember that they must all be different, and must
56 :			** also be different from any of the custom names used for components.
57 :			** Without that, Remosef cannot figure out what a SEF URL means and will
58 :			** give unpredictable results.
