Signed-off-by: Chip Childers <chip.childers@gmail.com> I've assumed that Gavin's commit is appropriate, based on an assumption that we will keep these files in the source tree. If https://issues.apache.org/jira/browse/LEGAL-146 results in a different opionion from the members, then we will end up having to do something more drastic anyway.
