Tango actually requires that version=Tango be set for the installation
to be considered complete. I suppose we could enforce this by adding a
static failure condition to Tango's object.d file, but I'd like to think
that making it a default part of the bundled Tango installs and
documenting the requirement in our manual install docs would be sufficient.
