Done. Therion is stuck waiting for current vtk package to transition
to testing, and both are stuck because the mipsel buildds can't keep up but it should be OK in a week or so.

We've been doing that for many, many years as it provides some useful
local documentation (although, checking, I see that the resolution of
some of the images is too low to be useful). I chose not to use cavern
so that the back-up calculation system in therion got tested. That
seemed more appropriate for the therion build. It also simplified the
build-dependency tree a little.

OK. But then the therion back-up functionality may hardly ever get
tested?

Now that we have autopackage tests (tests run after the build on the
installed packages), I guess we could run some tests both with and
without cavern installed (maybe - not sure if we have that level of
control). But we don't have the sample sources available to run a
runtime, only at build-time.

Using cavern is the 'normal' case so maybe it's better to do that at
build-time too. I'll try it.
