The same configuration is used to preserve style with one DTS-specific configuration (so that the DPDK docs are unchanged) that modifies how the sidebar displays the content. Sphinx generates the documentation from Python docstrings. The docstring format is the Google format [0] which requires the sphinx.ext.napoleon extension. The other extension, sphinx.ext.intersphinx, enables linking to object in external documentations, such as the Python documentation. There are two requirements for building DTS docs: * The same Python version as DTS or higher, because Sphinx imports the code. * Also the same Python packages as DTS, for the same reason.
