Subject: [PATCH 4/4] doc-rst: add ABI documentation to the admin-guide book
As we don't want a generic Sphinx extension to execute commands,
change the one proposed to Markus to call the abi_book.pl
script.
Use a script to parse the Documentation/ABI directory and output
it at the admin-guide.

- The ``kernel-cmd`` (:py:class:`KernelCmd`) directive includes contend
- from the stdout of a comand-line.
+ The ``kernel-abi`` (:py:class:`KernelCmd`) directive calls the
+ scripts/get_abi.pl script to parse the Kernel ABI files.
Overview of directive's argument and options.
.. code-block:: rst
- .. kernel-cmd:: <command line>
- :depends: <list of comma separated file names>
- :code-block: <language>
+ .. kernel-abi:: <ABI directory location>
:debug:
- The argument ``<command line>`` is required, it is a command line to be
- executed. The stdout stream of the command is captured and is inserted as
- reST content. The command line is executed in a system shell where the PATH
- environment is extended with the paths ::
-
- PATH=$(srctree)/scripts:$(srctree)/Documentation/sphinx:...
-
- ``depends <list of comma separated file names>``
-
- If the stdout of the command line depends on files, you can add them as
- dependency, which means: if one of the listed files is changed, the
- sphinx-build (environment) is newly build.
-
- ``code-block <language>``
-
- If the called script outputs a code-block, use the ``code-block`` option
- with an *language* as argument. The valid values for the highlighting
- language are:
-
- * none (no highlighting)
- * guess (let Pygments guess the lexer based on contents, only works
- with certain well-recognizable languages)
- * rest
- * c
- * and any other lexer alias that `Pygments
- <http://pygments.org/docs/lexers/>`_ supports.
+ The argument ``<ABI directory location>`` is required. It contains the
+ location of the ABI files to be parsed.
``debug``
Inserts a code-block with the *raw* reST. Sometimes it is helpful to see
what reST is generated.
- .. warning::
-
- The kernel-cmd directive **executes** commands, whatever poses a risk
- (shell injection) in itself!
-
- The command might depend on local installations, don't use commands which
- are not available in some OS (be clear about the dependencies).
