// TODO: (issue #264) break out the definition of brackets into a separate module from the application controller logic

/**
 * brackets is the root of the Brackets codebase. This file pulls in all other modules as
 * dependencies (or dependencies thereof), initializes the UI, and binds global menus & keyboard
 * shortcuts to their Commands.
 *
 * Unlike other modules, this one can be accessed without an explicit require() because it exposes
 * a global object, window.brackets.
