Hi all, On a regular basis, users of my 'tree.hh' library ask me whether I would be interested in submitting it to boost. As you may have guessed from the name, tree.hh is a templated n-ary tree container class in the spirit of the STL, but of course deviating from it in the sense of offering various ways of iterating over the tree. More info at http://www.aei.mpg.de/~peekas/tree/ Back in 2002 I tried to estimate the interest for inclusion in boost, see http://lists.boost.org/Archives/boost/2002/10/37383.php The most serious criticism back then was the 'lack of abstraction' (for more details please consult the original thread), and I didn't have the time to address that. Given the continuing interest by users of tree.hh to propose it for inclusion in boost, I would like to give this another shot and see what's the current opinion. While I would be happy to clean up the code, I do not have the time to do a substantial rewrite (along the lines suggested in 2002), but would be interested to help someone else do that. License-wise, tree.hh is now available under GPL-2 or 3, but all of the above of course implies that I'd be willing to re-license. Cheers, Kasper
