Hey Bryce,

I was toying with the idea of working up my new third party
software - WinBig (TM) - entirely as an exercise in testing
xdg-utils.

My thought was to have a process that was fairly heavy on user
interaction, as that struck me as necessary.  (e.g. Did the menu
show up?  Did the right app open blat.mime?)

But then I recalled that you'd started down that road, and
I didn't want to duplicate effort.  I took a quick glance,
and didn't see 'make test' in the current tip; have you had any further
thoughts with this?

Cheers,

Jeremy
