 This plugin generates a [manifest file](https://en.wikipedia.org/wiki/Manifest_file) listing the versioned asset files generated by your app's build process.  By comparing the latest manifest to the previous one, your deployment plugin (such as [ember-cli-deploy-s3](https://github.com/zapnito/ember-cli-deploy-s3)) can determine which files have changed and only upload those, improving efficiency.
