Hmm, maybe I overlooked that. But maybe not because it seems one still
needs to make all the same changes to the source when adding a module.

What I'm asking is that

1. a module can be built on its own, without also rebuilding the main
binary

2. getting a module to be used is as simple as installing it in the
magic directory, plus maybe _one_ explicit mention in a _runtime_
config file.

Of course we would need to define a precise interface that modules must
provide; I don't think this is quite the case now.
