Well, that's easily solved. The "tool" doesn't need to do everything on a
single invocation which leaves enough room for custom steps.

However, I do see the point of using different tools for that purpose. Yet
it would be convenient and time-saving to have everything under the same
roof within a common framework and good reference documentation :)
