I think it would be a good idea to keep boost.jam as some kind of patch
in respect to the 'official jam' (certainly since it started evolving
again) and since there a lot of other good patches (Matt Armstrong,
...). Of course, this way, boost.jam will probably evolve slower as we
would like but it will be better in the long run (btw we're a too small
community ourselves to maintain boost.jam ourselves : you are already
spending some much time on it).

If we would not keep boost.jam a patch to Jam, I think it's better to
take the more drastic decision to e.g. use Python (as Matt Armstrong
suggests is the msg : possibility of merged codebase.

So I think it's a good idea to suggest all the improvements maid by
boost.jam to the root jam, but item per item, starting with the items
that are easiest to integrate in the root. Boost.jam has so much evolved
that I guess the other people choke when they see the whole bunch of
changes at once.
