Yes, it would suck, cause then the reverse what is done above would
needs to happen. Sigh.

So, once it gets released properly, we will add breaks/replaces
against whatever the name of packages you will come up for it in the
PPA/jessie/for now. That way once boost.compute is upstream the
upgrade path will be easy once enough time passes.

So go for "* packaging Boost.Compute standalone" and we will work to
have a sensible upgrade path later, when needed.
