The Sphinx theme can be overridden by using the ``DOCS_THEME`` make variable.
There is another make variable ``SPHINXDIRS``, which is useful when test
building a subset of documentation. For example, you can build documents
under ``Documentation/doc-guide`` by running
``make SPHINXDIRS=doc-guide htmldocs``.
The documentation section of ``make help`` will show you the list of
subdirectories you can specify.
To remove the generated documentation, run ``make cleandocs``.
