I guess this is partly technical and partly organizational problem.
In order to have boost.jam appear as a patch to the perforce jam, of even
better, as a number of patches from which interested persons can select
needed features, the best option would be to have boost.jam version in
Perforce public depot (in David's branch now) to
1. correspond exactly to the version in the Boost CVS
2. to have detailed change history, so that anybody who wants, say, modules,
will know the numbers of changes that he should integrate to get modules
support. (I think p4 has a feature to integrate a set of changes, given they

Of cause, it would take time to produce such a history for existing
enhancements. For future ones, this is very desirable. But this requires some
effort on developers part. Syncing Boost CVS & public depot will be extra
burden as well... unless Boost CVS is no longer used for Boost.Jam
