// There are two flavors of auto-start, separated by whether a window is

// the other flavor might have been requested).
// NOTE: Chrome being set to launch in the background (without a window)
// does not necessarily mean that Chrome *will* launch without a window, since
// when both flavors of the auto-start feature have been requested. In other
// words, showing a window trumps not showing a window.
// ALSO NOTE: |application_path| is optional and should be blank in most cases
// (as it will default to the application path of the current executable).
