+I have placed the Bourne shell scripts in the `bin` directory. I have
+also included tests for these scripts in the `test` directory. To run
+the tests you will need to install [bats](https://github.com/sstephenson/bats).
+To make installation easier, I have included [bats](https://github.com/sstephenson/bats) as a git submodule.
+
+```bash
+$ git submodule update --init
+$ sh ./bin/test
