Is it allowed to have back dependency on chrome from components? Can we create
copresence_switches.cc instead?

[Daniel Erat, 2014/08/06 00:44:46]

no, this isn't allowed, and yes, dependencies that are shared between chrome/
and something under components/ should live in components/.

[Charlie, 2014/08/06 19:32:17]

Done.
