nit: "Launch app" since it's in not title_case section.

[Nikita (slow), 2014/02/12 17:19:25]

Done.
Do you know how this is used?

[xiyuan, 2014/02/12 17:35:03]

It is used in common.gypi and true for gtk, mac and ios.
https://code.google.com/p/chromium/codesearch#chromium/src/build/common.gypi&...

Probably does not makes sense for chromeos but since we share code with desktop
user manager now, it is better to follow the convention.
