* Welcome to the source-code. This is a good point to start reading.
*
* This is index.php - the master-control-page. There are NO other php-pages, except from
* install.php (which should have been deleted in normal installations).
*
* index.php does...
*
* 1. initialize the profiler
* 2. include config and customize
* 3. include core-components
* 4. authenticate the user
* 5. render a page (which means calling a function defined in a file at pages/XXX.inc)
