Version 0.99.0

The command-line tool's S3 gateway now decides by a file's content instead of its name, so re-sending a file that is already stored costs nothing.

A backup program's job is to send the same names every night, and the gateway refused every one of them because something was already at that key — which a sync tool records as a failure. It now compares the arriving bytes against the hash this account encrypted when the file was first stored, and answers that the file is there without sending it. A key holding a different file is still declined, because this drive does not replace files, and a file stored before those hashes were recorded says it cannot tell rather than claiming to know. This is in nmts 0.7.0.
