Yes, it's a relatively straightforward tool.  It would be nice to have a
completely open-source bbv generating tool available to the general
public.  I must admit some of my reasons for wanting it merged are a bit
selfish; I mainly hate messting around with automake and configure files
whenever I want to build the tool on a new machine.

I really need to get some test cases too.  Trying to get things in shape
for merging with a public tree is a good incentive for getting around to
lots of testing and code cleanup.

You're right, I hadn't thought about that!  I've made this change, and now
my tool runs at least twice as fast as it used to.

Thanks

Vince
