Well, since Tango downloads are available that include Tangobos now, it might be
less of an issue than it was before. If people want "pure Tango" examples they can
find them in the Tango wiki. If people don't mind using Tangobos, most of the
tutorials should run without any modification needed. (I guess I might install a
recent version of Tango to see if this is true.)
