S3/Swift REST API Comparison Matrix
===================================

General compatibility statement
-------------------------------

S3 is a product from Amazon, and as such, it includes "features" that
are  outside the scope of Swift itself. For example, Swift doesn't
have anything to do with billing, whereas S3 buckets can be tied to
Amazon's billing system. Similarly, log delivery is a service outside
of Swift. It's entirely possible for a Swift deployment to provide that
functionality, but it is not part of Swift itself. Likewise, a Swift
deployment can provide similar geographic availability as S3, but this
is tied to the deployer's willingness to build the infrastructure and
support systems to do so.
