AWS S3 support: docs?

[Richard Gaskin]

Apparently v9 added support for Amazon's S3, but I can't find 
documentation on it.

I see mention of it in the Release Notes for v9 and later, e.g.:

    Amazon Web Services (AWS) Library
    The new Amazon Web Services library includes support for Amazon
    Simple Storage Service (S3). You can use S3 to provide cloud
    storage for your app. Read more here

   https://livecode.com/docs/9-5-0/whats-new/release-notes/

Unfortunately, the "Read more here" link goes to Amazon AWS, where they 
provide no documentation on using their service with LiveCode.

I tried looking in the LC Dictionary, but searching for "aws" and "s3" 
yield nothing.

Clues?
