The boost/filesystem directory currently looks like this: v2 config.hpp // actual header convenience.hpp exception.hpp fstream.hpp operations.hpp path.hpp v3 config.hpp // actual header convenience.hpp exception.hpp fstream.hpp operations.hpp path.hpp config.hpp // forwards to v2/config.hpp or v3/config.hpp convenience.hpp exception.hpp fstream.hpp operations.hpp path.hpp It is time to remove the dual version support. What I'd like to do is: * create a branch, * switch to it, * delete the top level forwarding headers, * move the v3 headers up to boost/filesystem, * delete the v2 and v3 directories, * modify the headers as needed, * merge back to trunk. At the completion of the merge, the history for the boost/filesystem headers should include the full history of what were the boost/filesystem/v3 headers. What are the svn commands to accomplish that? Thanks, --Beman
