Buxscript is a unique PTC and Aurora module, that is powered by drupal. Due to use of a content management system Content Management System (CMS), our Buxscript is built to deliver maximum functionality to our customers by simply uploading the modules, themes and translations from http://drupal.org onto the web server.
It has the ability for the administrator to create and manage content (pages and menus) without programming skills. Add new functionalities and themes (templates) with the click of a button. Other benefits include the added security and administrative power provided by the content management system and free modules people have contributed over the years.
The use of a CMS gives the administrators of the buxscirpt total control. You might want to know what is drupal and get a drupal tutorial.
