Xataface Application Framework
This action is more for backward compatibility with Dataface 0.5.x than anything else. Dataface 0.5.x allowed developers to place php scripts in a directory named 'pages' in their application folder to essentially serve as custom actions but to a much more limited extent than the current actions framework. This action is triggered by "-action=-custom_<pagename>" where <pagename> is the name of the php script in the "pages" directory omitting the '.php' extension. For example. If you had a script pages/home.php then you would access this page with -action=custom_home .
