The root document usually has a special :ref:`genindex` link to the generated index. This is also the case for Documentation/index.rst. The other index.rst files deeper in the directory hierarchy usually don't. For SPHINXDIRS builds, the root document isn't Documentation/index.rst, but some other index.rst in the hierarchy. Currently they have a ".. only::" block to add the index link when doing SPHINXDIRS html builds. This is obviously very tedious and repetitive. The link is also added to all index.rst files in the hierarchy for SPHINXDIRS builds, not just the root document. Put the boilerplate in a sphinx-includes/subproject-index.rst file, and include it at the end of the root document for subproject builds in an ad-hoc source-read extension defined in conf.py. For now, keep having the boilerplate in translations, because this approach currently doesn't cover translated index link headers.

Core API Documentation
|
|
======================
|
|
|
|
This is the beginning of a manual for core kernel APIs. The conversion
|
|
(and writing!) of documents for this manual is much appreciated!
|
|
|
|
Core utilities
|
|
==============
|
|
|
|
This section has general and "core core" documentation. The first is a
|
|
massive grab-bag of kerneldoc info left over from the docbook days; it
|
|
should really be broken up someday when somebody finds the energy to do
|
|
it.

Memory management
