* There is an entire library, Boost.Compose, long since deprecated and removed from svn in favor of Boost.Bind or Boost.Lambda, present in the git repos, both in master and develop. * Boost.Interprocess, git develop contains a header libs\include\boost\interprocess\fully_mapped_file.hpp that does not appear in the svn trunk head. * Boost.Type-Traits, git develop contains a header directory, \include\boost\detail, with two header files. Neither these two headers nor the directory are present in svn trunk head. * All 9974 headers in svn trunk/boost head have git super-project boost header entries generated by "b2 headers" and the content, ignoring end of line differences, is identical in all of them. * Exactly the same 5680 regression tests passed for both svn trunk head and git develop head. It doesn't get any better than that! --Beman
