* Ignore `docs/_build`
* Remove `v` prefix from VERSION. Also added a `lib-doc` target
* Raise a `ValueError` instead of `NotImplementedError`
* Add all registered http method verbs
* Generate `_scm_version.py` on every `make` invocation. Fix `v` prefix bug.
* `+proxy` for emails
* Make explicit that this script writes to file
* `PROXY_AGENT_HEADER_VALUE` still needs the `v` :)
