Zen Cart 1.3.8a
Database Patch Level: 1.3.8
Server OS: Linux 2.4.20PIII
PHP Version: 4.4.2 (Zend: 1.3.0)
Database: MySQL 4.1.19-standard

I would like to override the functions in the html_output.php file that output HTML tags.

Where do I put these functions, and what replacement structure do I need to use to remove / disregard the previously defined versions of these functions so I dont end up with PHP errors saying I duplicated something.
