// This file provides several functions to explicitly request the various
// component bundles of Chrome. Please use these methods rather than calling
// +[NSBundle mainBundle] or CFBundleGetMainBundle().
//
// Terminology
// - "Outer Bundle" - This is the main bundle for Chrome; it's what
// +[NSBundle mainBundle] returns when Chrome is launched normally.
//
// - "Main Bundle" - This is the bundle from which Chrome was launched.
// This will be the same as the outer bundle except when Chrome is launched
// via an app shortcut, in which case this will return the app shortcut's
// bundle rather than the main Chrome bundle.
//
// - "Framework Bundle" - This is the bundle corresponding to the Chrome
// framework.
//
// Guidelines for use:
// - To access a resource, the Framework bundle should be used.
// - If the choice is between the Outer or Main bundles then please choose
// carefully. Most often the Outer bundle will be the right choice, but for
// cases such as adding an app to the "launch on startup" list, the Main
// bundle is probably the one to use.
// Methods for retrieving the various bundles.
