 /**
- * @file
- * drush is a PHP script implementing a command line shell for Drupal.
+ * This script runs Drush.
+ *
+ * Responsibilities of this script:
+ *   - Locate and include the Composer autoload file for Drush.
+ *   - Set up the environment (record user home directory, cwd, etc.).
+ *   - Call the Preflight object to do all necessary setup and execution.
+ *   - Exit with status code returned
  *
- * @requires PHP CLI 5.4.5, or newer.
+ * It is our goal to put all $_SERVER access and other constructs that are
+ * difficult to test in this script to reduce the burden on the unit tests.
+ * This script will only be tested via the functional tests.
+ *
+ * The Drush bootstrap goes through the following steps:
+ *   - (ArgsPreprocessor) Preprocess the commandline arguments, considering only:
+ *     - The named alias `@sitealias` (removed from arguments if present)
+ *     - The --root option (read and retained)
+ *     - The --config option (read and retained)
+ *     - The --alias-path option (read and retained)
+ *   - Load the Drush configuration and alias files from the standard
+ *     global locations (including --config and --alias-path)
+ *   - Determine the local Drupal site targeted, if any
+ *   - Include the Composer autoload for Drupal (if different)
+ *   - Extend configuration and alias files to include files in target Drupal site.
+ *   - Create the Robo DI container and Symfony Application et. al.
+ *   - Run the Symfony Application
+ *     - Predispatch: call a remote Drush command if applicable
+ *     - Bootstrap Drupal via @bootstrap command hook
+ *     - Run commands and command hooks via annotated commands library
+ *     - Catch 'command not found' exception, bootstrap Drupal and run again
+ *   - Return status code
