/**
* This file is the Framework constants bootstrap. It will prepare some basic common constants.
*
* It takes care of:
* - Including _ss_environment.php
* - Normalisation of $_SERVER values
* - Initialisation of necessary constants (mostly paths)
*
* Initialized constants:
* - BASE_URL: Full URL to the webroot, e.g. "http://my-host.com/my-webroot" (no trailing slash).
* - BASE_PATH: Absolute path to the webroot, e.g. "/var/www/my-webroot" (no trailing slash).
* See Director::baseFolder(). Can be overwritten by Config::inst()->update('Director', 'alternate_base_folder', ).
* - TEMP_FOLDER: Absolute path to temporary folder, used for manifest and template caches. Example: "/var/tmp"
* See getTempFolder(). No trailing slash.
* - MODULES_DIR: Not used at the moment
* - MODULES_PATH: Not used at the moment
* - THEMES_DIR: Path relative to webroot, e.g. "themes"
* - THEMES_PATH: Absolute filepath, e.g. "/var/www/my-webroot/themes"
* - FRAMEWORK_DIR: Path relative to webroot, e.g. "framework"
* - FRAMEWORK_PATH:Absolute filepath, e.g. "/var/www/my-webroot/framework"
* - FRAMEWORK_ADMIN_DIR: Path relative to webroot, e.g. "framework/admin"
* - FRAMEWORK_ADMIN_PATH: Absolute filepath, e.g. "/var/www/my-webroot/framework/admin"
* - THIRDPARTY_DIR: Path relative to webroot, e.g. "framework/thirdparty"
* - THIRDPARTY_PATH: Absolute filepath, e.g. "/var/www/my-webroot/framework/thirdparty"
* - TRUSTED_PROXY: true or false, depending on whether the X-Forwarded-* HTTP
* headers from the given client are trustworthy (e.g. from a reverse proxy).
*
* @package framework
* @subpackage core
