Guidelines for any code contributions:

1.  Any significant changes should be accompanied by tests. The project already
    has good test coverage, so look at some existing tests if you're unsure how
    to go about it.
2.  All contributions must be licensed Apache 2.0 and all files must have a copy
    of the boilerplate license comment (can be copied from an existing file).

### Docs for tests

Most of the tests actually run against the example source files in the documentation.

This helps to make sure that:

* The documentation is up-to-date.
* The documentation examples can be run as is.
* Most of the features are covered by the documentation, ensured by test coverage.

#### Apps and docs at the same time
