Is it D-Bus, DBus, D-BUS or dbus?

[Havoc Pennington]

I was consciously trying to use D-BUS consistently, but I certainly 
can't give you some kind of rational reason for it.

Of course in code I usually used dbus or DBus for the namespace.

The name D-BUS was essentially a joke; I seem to recall a lot of stupid 
puns being exchanged on IRC. (e.g., you will notice we still have 
dbus/bus/driver.c...) Putting it in all caps made it more amusing perhaps.
