Other initialization steps such as requesting devices may also be
performed here.
When the repository is scanned, any requested devices and arguments
are set to ``None``.
There are two situations where the requested devices are replaced by
``DummyDevice()`` and arguments are set to their defaults (or ``None``)
instead: when the repository is scanned to build the list of
available experiments and when the dataset browser ``artiq_browser``
is used to open or run the analysis stage of an experiment. Do not
rely on being able to operate on devices or arguments in ``build()``.
Datasets are read-only in this method.
