Nope, as far as I know, it's not being used at all at the moment. The idea
was we could use it to avoid having multiple recipes with different
versions and .inc includes all over the place, but then policy changed to
tend to prefer having just a single recipe version around, so it's of less
use. If you'd like to see an example of a prototyped recipe using it, which
I created while implementing BBVERSIONS, see
https://gist.github.com/kergoth/338382. This was an attempt, at the time
(2010) to have a single m4 recipe that was capable of building every m4
version that existed. It was mostly to see if it could be done :)
