drive
One verb for every desktop.
The pass-through to whichever drive backend this OS has: baton drive <anything> hands the arguments verbatim to mac-drive, lin-drive or win-drive, locally or on a peer with --node. baton holds no model of the verbs — it probes for a binary and gets out of the way, so a new backend capability needs no baton release. doctor reports what is installed and operable.
