Yes, I understand that some of us have a (reasonable) doubt about
the reST markup. It is not perfect in any matter, e.g. I don't like
the ``monospace`` markup. But this is my home opinion.

My hope is, that those of us who have a doubt give reST
a chance ... it is a compromise, not as bad as you might
think first ... your cooperation and your criticism is
needed and welcome. Please let me invite you / read on:

There are other plain-text markups e.g. AsciiDoc or Markdown. The
reST markup and the Sphinx-builder is a compromise from a evaluation
in 2016 (see linux-doc ML subject "muddying the waters" [1]).

Jani wrote an article about the evaluation and it results [2]. And
there are other articles documenting all the various aspects.

- A report from the documentation maintainer [3]
- Kernel documentation with Sphinx, part 2: how it works [4]
- Kernel documentation update [5]

To summarize it with my words:

The old DocBook-based toolchain was hard to maintain and of course
who want's to write XML? A consistent plain-text markup for
articles in /Documentation/* and source-code comments (kernel-doc)
was needed.

The markup: IMO reST wins that race, because it has a extendable
markup specification while others plain-text markups like Markdown
have various (HTML) builders with various markup dialects[7] (which
is more a mess than a definition).

The builder: IMO Sphinx-Doc wins that race, since it is (well)
maintained, widely used and has a interface for extensions.
I.e. the one extension we wrote: 'kernel-doc' to parse kernel-doc
comments from source code and include them in the articles.
Perspective: Sphinx-Doc also offers solutions we might use in the
future (e.g. building man-pages). Not to end in a mess, extensions
should be implemented cautiously and deliberately (be patient).

But that should not fool you; yes we have known problems with our
toolchain and it is not yet ;) perfect in any matter (e.g. the
highlighting in kernel-doc comments or the PDF generation or the
sphinx-doc versions shipped with various distributions or ..)

Anyway, today we have more than before: The reST learning curve is
(compared to DocBook) not hard for newbees and our toolchain is
flexible for all the requirements wich might come up in the future.

IMO the actual challenge is the content and the organization
of the doc-tree and for this

Thats exactly what I mean: give reST a chance :)
