// Win8 default browser registration utility.

// This tool can register and unregister a given exe as a potential default

// for a mechnism to do this please see open_with_dialog_controller.h.

// TODO(robertshield): By default, this creates a run-time dependency on
// chrome.exe since it's the only thing we have right now that works as a
// default viewer process. Investigate extracting the metro init code and
// building them into a standalone viewer process.
