Hi Ed, I think that sounds great. In the future, could we go even further and, = by default, only emit date/user/path if the source tree is =E2=80=9Cdirty= =E2=80=9D = with respect to SVN? If the build really is reproducible, that data = should only be informative when building something that doesn=E2=80=99t m= atch = a FreeBSD SVN revision (e.g., a Git commit in a local repo or a tree = with local changes).
