<?php
/**
* 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 Director::setBaseFolder().
* - 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"
* - CMS_DIR: Path relative to webroot, e.g. "cms"
* - CMS_PATH: Absolute filepath, e.g. "/var/www/my-webroot/cms"
* - SAPPHIRE_DIR: Path relative to webroot, e.g. "sapphire"
* - SAPPHIRE_PATH:Absolute filepath, e.g. "/var/www/my-webroot/sapphire"
* - THIRDPARTY_DIR: Path relative to webroot, e.g. "sapphire/thirdparty"
* - THIRDPARTY_PATH: Absolute filepath, e.g. "/var/www/my-webroot/sapphire/thirdparty"
*
* @package sapphire
* @subpackage core
