Maven S3 Wagon
This wagon enables communication between Maven and Amazon S3.
pom's with a reference to this wagon can publish build artifacts (.jar's, .war's, etc) to S3.
When uploading the contents of a directory, API calls to S3 are multi-threaded.
This allows directories with a lot of content (eg when invoking mvn site-deploy) to be published very quickly
