For src, you're going to want `dist/*.css`. Also just set the ext to `` (so the filenames are not changed)

Since we are going to be uploading this to s3, I think it will be better to set the `dest: s3/` and then add
`s3/` to `.gitignore` file. That way the gzipped files won't get committed but when we  do automatic uploads, it can look at that folder.
