/**
* Main file that handles every page request.
*
* The main.php does a number of set-up activities for the request.
*
* - Includes the first one of the following files that it finds: (root)/_ss_environment.php,
* (root)/../_ss_environment.php, or (root)/../../_ss_environment.php
* - Gets an up-to-date manifest from {@link ManifestBuilder}
* - Sets up error handlers with {@link Debug::loadErrorHandlers()}
* - Calls {@link DB::connect()}, passing it the global variable $databaseConfig that should
* be defined in an _config.php
* - Sets up the default director rules using {@link Director::$rules}
*
* After that, it calls {@link Director::direct()}, which is responsible for doing most of the
* real work.
*
* CONFIGURING THE WEBSERVER
*
* To use SilverStripe, every request that doesn't point directly to a file should be rewritten to
* framework/main.php?url=(url). For example, http://www.example.com/about-us/rss would be rewritten
* to http://www.example.com/framework/main.php?url=about-us/rss
*
* It's important that requests that point directly to a file aren't rewritten; otherwise, visitors
* won't be able to download any CSS, JS, image files, or other downloads.
*
* On Apache, RewriteEngine can be used to do this.
