This package uses raml-client-generator as a framework for generating macro files. (You may also just use the language/python directory as a plug-in, if you're using more than just python)
for the code generation, you'll need to run
npm install
sh test.sh
This will generate a bunch of python files in the directory 'igpy' for various python web clients and servers.
For more details of what's generated, see the README.md in the language/python folder.
