script, but it is better to put it into some context.

===========================
Including uAPI header files
===========================
Sometimes, it is useful to include header files and C example codes in
order to describe the userspace API and to generate cross-references
between the code and the documentation. Adding cross-references for
userspace API files has an additional vantage: Sphinx will generate warnings
if a symbol is not found at the documentation. That helps to keep the
uAPI documentation in sync with the Kernel changes.
The :ref:`parse_headers.pl <parse_headers>` provide a way to generate such
cross-references. It has to be called via Makefile, while building the
documentation. Please see ``Documentation/media/Makefile`` for an example
about how to use it inside the Kernel tree.
