Travis: Deploy to S3 rather than SourceForge This has the following advantages: -- It doesn't require checking a private SSH key into the repository. (With SourceForge, an SSH key is the "keys to the kingdom".) -- If the S3 key is compromised, it is very easy to revoke it and generate a new one. -- The S3 bucket is isolated, so even if it becomes compromised, then the damage that one could do is limited. -- It's much easier to manage files through S3's web interface than through SourceForge. -- The files are served via HTTPS. -- Travis fully supports S3 as a deployment target, so this simplifies .travis.yml somewhat.
