+// Win8 default browser registration utility.
+//
+// This tool can register and unregister a given exe as a potential default
+// metro browser on Win8. It does not make the exe become THE default browser,
+// 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.
