24 // This file provides several functions to explicitly request the various
25 // component bundles of Chrome.  Please use these methods rather than calling
26 // `+[NSBundle mainBundle]` or `CFBundleGetMainBundle()`.
27 //
28 // Terminology
29 //  - "Outer Bundle" - This is the main bundle for Chrome; it's what
30 //  `+[NSBundle mainBundle]` returns when Chrome is launched normally.
31 //
32 //  - "Main Bundle" - This is the bundle from which Chrome was launched.
33 //  This will be the same as the outer bundle except when Chrome is launched
34 //  via an app shortcut, in which case this will return the app shortcut's
35 //  bundle rather than the main Chrome bundle.
36 //
37 //  - "Framework Bundle" - This is the bundle corresponding to the Chrome
38 //  framework.
39 //
40 // Guidelines for use:
41 //  - To access a resource, the Framework bundle should be used.
42 //  - If the choice is between the Outer or Main bundles then please choose
43 //  carefully.  Most often the Outer bundle will be the right choice, but for
44 //  cases such as adding an app to the "launch on startup" list, the Main
45 //  bundle is probably the one to use.
