Re: [boost] Changing the arrangement of files within our SCM

...

This plan will work better with Subversion, since that SCM system records file _and_ directory moves.

Not strictly true. It keeps track of deletes and adds. The moves/renames are implemented in terms of those which means that getting the history of files in place is not possible. (Last I checked)

In subversion, moves are a copy, followed by the deletion of the original; the copy is history-preserving.
