Global flag to identify update.php and authorize.php runs, and so avoid various unwanted operations, such as hook_init() and hook_exit() invokes, css/js preprocessing and translation, and solve some theming issues. This flag is checked on several places in Drupal code (not just authorize.php).

File

./authorize.php, line 35

Administrative script for running authorized file operations.
