273273In brief, a mark file contains a `door` with three arms. The door's sample type is the type of the data in question - in our case the `$user` structure. The `+grab` arm contains methods for converting _to_ our mark, and the `+grow` arm contains methods for converting _from_ our mark. The `+noun` arms are mandatory, and then we've added `+json` arms which respectively call the `+from-js` and `+to-js` functions from our `json-test.hoon` library. The final `+grad` arm defines various revision control functions, in our case we've delegated these to the `%noun` mark.
