Bulk moving asset folders, from one source to another I'm moving all of my assets from a local folder to Amazon S3. I've got my S3 source all set up, and I've been migrating folders over to it by dragging &amp; dropping.

The problem is, I have thousands of asset folders. I did the math, and it'll take me 4+ hours to drag &amp; drop each of them.

Is there some way to bulk move asset folders?

If it's not possible in the CP, I'm open to plugin suggestions as well.
I did this with grunt, using the grunt-aws-s3 task. It worked beautifully. If you are a gulp person, I'm sure there is something similar for gulp.
