+// Autoloading of dependencies.
+// Three options are supported:
+// 1. If dependencies are installed with Composer, Composer will create a
+//    vendor/autoload.php. If this file exists it will be
+//    automatically used by phpBB. This is the default mode that phpBB
+//    will use when shipped.
+// 2. To disable composer autoloading, PHPBB_NO_COMPOSER_AUTOLOAD can be specified.
+// 	  Additionally specify PHPBB_AUTOLOAD=/path/to/autoload.php in the
+//    environment. This is useful for running CLI scripts and tests.
+//    /path/to/autoload.php should define and register class loaders
+//    for all of phpBB's dependencies.
+// 3. You can also set PHPBB_NO_COMPOSER_AUTOLOAD without setting PHPBB_AUTOLOAD.
+//    In this case autoloading needs to be defined before running any phpBB
+//    script. This might be useful in cases when phpBB is integrated into a
+//    larger program.
