+- copy the appropriate manifest-xxx.json file to manifest.json; e.g. `mv manifest-chrome.json manifest.json`
+- zip using [grunt](https://stackoverflow.com/questions/15703598/how-to-install-grunt-and-how-to-build-script-with-it), which requires npm and node. Run `grunt` in top-level directory. The add-on is packaged into `target.zip`. Alternatively, zip the `src` directory into the top of an archive and exclude a bunch of stuff manually.
