We should really clean this up. The different tools should be supported outside
of this method in something like RegisterInTools. Does not have to happen in
this CL, but if you do not factor this out before the end of the week, please
file a tracking bug.

Refactored.

This seems rather error prone, as the checking is done at two places. Falls into
the same category as above.
