Hi Joel,
Nice christmas gift you made us! Sorry for the delays, my backlog is, err,
significant :)

This is nice work. I have not read it in all the details, but it is, as usual,
well commented, documented, and tested. Yet, I expected to find some reference
to some published work. Do you have something about this?
I think we should create a Reference section pointing to the various papers on
top of which Bison is built.
How far do you think 2.5 is from being released? Rough estimation, of course.
