* This file is the Sapphire bootstrap. It will get your environment ready to call Director::direct().

*
|
|
* It takes care of:
|
|
* - Including _ss_environment.php
|
|
* - Normalisation of $_SERVER values
|
|
* - Initialisation of TEMP_FOLDER, BASE_URL, BASE_PATH, and other SilverStripe defines
|
|
* - Checking of PHP memory limit
|
|
* - Including all the files needed to get the manifest built
|
|
* - Building and including the manifest
|
|
*
|
|
* @todo This file currently contains a lot of bits and pieces, and its various responsibilities should probably be
|
|
* moved into different subsystems.
|
|
* @todo A lot of this stuff is very order-independent; for example, the require_once calls have to happen after the defines.'
|
|
* This could be decoupled.
