----------------------------------------

Steve, thank you for the update.  I have entered a few more small comments on 
pull request #130.  I think this is close to being ready after addressing those 
comments and getting another pre-commit run.

> An AWS SDK [issue|https://github.com/aws/aws-sdk-java/issues/367] highlights 
> that metadata isn't copied on large copies.
> 1. Add a test to do that large copy/rname and verify that the copy really 
> works
> 2. Verify that metadata makes it over.
> Verifying large file rename is important on its own, as it is needed for very 
> large commit operations for committers using rename
