I'm writing this as a fun app to build for my wife to store all her recipe cards electronically. I'm also using it as a way to learn the "proper" way to do a GAE-backed AngularJS app (because getting paid to do such does not always generate "proper" code).
Soon I'll be writing tests (Angular unit, Angular e2e, and Python unit) as I learn how to actually do that.
Well feel free to fork I suppose. No official method right now.
I really don't know how this works yet. So eventually I'll probably put some license up here, but for now I guess this is considered what "no-license" projects are considered (closed source?).
