I am still learning git ( I like what I see ). I did check out his git-hub repository, but I was unable to figure out how 'overlay' his repos on a working boost chain or pull out just the parts he was using. Besides, I would like to support the efforts of Boost.CMake and/or Ryppl, both of which use cmake and a 'modular' approach allowing me to checkout 'just boost context' all in one directory and then collaborate on that repository.

Because git does not allow you to manage externals in the same way subversion does (pointing at any subtree of the repo), it makes sense to keep each library in a self contained git module that does not split itself into boost/context and lib/context parts.

Right now I see advantages in Boost.Cmake over Ryppl in that Ryppl is more tied to git, where as Boost.Cmake is more flexible with respect to getting the sources. I have checked out and built the projects for both and it seems like, in the short term Boost.CMake has the advantage over Ryppl, but in the long-term I think Ryppl will be the best. Either way, the module structure should be fairly close, thus making it easy to port from one system to the other or even support both at once. In this way we can give feed back to the developers working on these ideas.

Is anyone doing active development of their boost components under either of these modular systems?

Anyway, I agree with the creator of Ryppl when he said at Boostcon 2010 that the boost build process sucks the joy out of development. I want to focus on actual code, not fighting with a difficult boost-centric build system that cannot even handle (on Mac OS X ) passing bjam extra options required by Boost.Context without messing up the commands fed to sh. I have already spent 16+ hours just trying to get my 'environment' set up in a way that I can efficiently stay up to date with the trunk, submit patches that are easily merged, and work on my own private libraries.

Perhaps a veteran boost developer could share their 'day-to-day' process for staying up to date, making patches, etc. Perhaps it is not so bad if you know bjam through and through.
