Please note you must execute this script with the same uid as apache!

Site defaults may be changed via local/defaults.php.

Options:
--non-interactive     No interactive questions or confirmations
--allow-unstable      Upgrade even if the version is not marked as stable yet,
                      required in non-interactive mode.
--lang=CODE           Set preferred language for CLI output. Defaults to the
                      site language if not set. Defaults to 'en' if the lang
                      parameter is invalid or if the language pack is not
                      installed.
--verbose-settings    Show new settings values. By default only the name of
                      new core or plugin settings are displayed. This option
                      outputs the new values as well as the setting name.
-h, --help            Print out this help

\$sudo -u www-data /usr/bin/php admin/cli/upgrade.php
