The Boost Property Map Library (property_map) currently consists of a number of files in the top-level boost/ include directory. It would probably be better to move all of them into a subdirectory, especially as Nick Edmonds and I will be adding new files and directories into that library soon. Should I do that move? I will update Boost.Graph; are there other libraries in Boost that use property_map?
You never know who is using the files outside the boost tree. Don't remove them altogether just that. As a safeguard, you could put forwarding headers into the Boost root instead of the old files. Those could be flagged to be deprecated (add some warnings - see the boost/spirit.hpp forwarding header for an example) and may be removed two or three versions from now. Regards Hartmut
