+# Command Line Tools
+
+# Service Packager
+
+The command line tool `bin/service_packager`, when called with the following command line:
+
+```bash
+service_packager proto_file -o output_path -n name -v version [-i input_path...]
+```
+
+Populates `output_path` with a node package consisting of a `package.json` populated with `name` and `version`, an `index.js`, a `LICENSE` file copied from gRPC, and a `service.json`, which is compiled from `proto_file` and the given `input_path`s. `require('output_path')` returns an object that is equivalent to
+
+```js
+{ client: require('grpc').load('service.json'),
+ auth: require('google-auth-library') }
+```
