Diane, idea for Command is excelent! I (and assuming, the others) will
find it very handy, since it will remove various hacks we did in the
past. Btw. thank you for the patch.

David, any chance FTJam be synced with the jam 2.5? I'm using ftjam often,
but some "new tools" in 2.5 (for example GLOB) are very handy when
someone wants to write quick builds for large projects; not to say that
would be nice to reuse Autojam library with it :)
