// Purpose: Provide the main functions that are called in every Dragons
//		contents page. Initially this includes code ensuring that frames
//		work correctly, and the file last modified date/time string code.

// A generic function run in the header of every content page, to make
// the code more extensible.

//Handles putting the content page into the frame set (the content page
//part of it anyway), and renaming the title bar correctly
