 /**
  * Elgg Installer.
- * Controller for installing Elgg.
+ * Controller for installing Elgg. Supports both web-based on CLI installation.
+ *
+ * This controller steps the user through the install process. The method for
+ * each step handles both the GET and POST requests. There is no XSS/CSRF protection
+ * on the POST processing since the installer is only run once by the administrator.
+ *
+ * The installation process can be resumed by hitting the first page. The installer
+ * will try to figure out where to pick up again.
+ *
+ * All the logic for the installation process is in this class, but it depends on
+ * the core libraries. To do this, we selectively load a subset of the core libraries
+ * for the first few steps and then load the entire engine once the database and
+ * site settings are configured. In addition, this controller does its own session
+ * handling until the database is setup.
+ *
+ * There is an aborted attempt in the code at creating the data directory for
+ * users as a subdirectory of Elgg's root. The idea was to protect this directory
+ * through a .htaccess file. The problem is that a malicious user can upload a
+ * .htaccess of his own that overrides the protection for his user directory. The
+ * best solution is server level configuration that turns off AllowOverride for the
+ * data directory. See ticket #3453 for discussion on this.
