This is a draft of my work for c-hglib up to now, I am sending this to the list
for public review (even if this is not a patch for the core mercurial). I am
sure that the main developers following my work (Matt, Pierre-Yves, Idan and
others) will have important remarks on the architecture and on the style, and I
like to solicit those feedbacks.
I know that all of you are very occupied those days with the freeze phase, but
when you find some time please make a review.
