# Module selenium-webdriver/_base

code »

The base module responsible for bootstrapping the Closure library and providing a means of loading Closure-based modules.

Each script loaded by this module will be granted access to this module's `require` function; all required non-native modules must be specified relative to this module.

This module will load all scripts from the "lib" subdirectory, unless the SELENIUM_DEV_MODE environment variable has been set to 1, in which case all scripts will be loaded from the Selenium client containing this script.

## Classes
