Now that all the DocBook documentation is gone, we can switch to the
new NixOS documentation generator. No meaningful change in HTML output,
except that I removed the rather pointless preface and changed the
title accordingly. Manual page output is greatly improved; it was
kind of broken before. The `sed` hack is pretty gross but I have
confirmed that nixpkgs will be happy to accept a PR to make things
a little more customizable.
This also drops the `manual` alias (deprecated in nixpkgs in 2018
and imported into nix-darwin), and `manualEpub` (because the NixOS
documentation generator doesn't support it and also nobody wants this
as an ebook).
This process was automated by [my fork of `nix-doc-munge`]; thanks
to @pennae for writing this tool! It automatically checks that the
resulting documentation doesn't change, although my fork loosens
this a little to ignore some irrelevant whitespace and typographical
differences.
As of this commit there is no DocBook remaining in the options
documentation.
You can play along at home if you want to reproduce this commit:

These all use DocBook markup too complex for `nix-doc-munge` to handle,
have syntax that clashes with Markdown, or already contain Markdown
syntax that currently isn't rendering correctly.
Converting DocBook list syntax makes me think that maybe Markdown
isn't so bad after all.
These help `nix-munge-doc` automate more of the Markdown conversion
process. See the following nixpkgs commits for explanations of many
of these changes:
* 275a34e0d8
* 694d5b19d3
* f1d39b6d61
* 16102dce2f
I couldn't think of any particularly good way to format the
`system.defaults` breadcrumbs, so I just made them standalone
paragraphs. They weren't rendering correctly in DocBook anyway.
The only change to `options.json` are that the `declarations` fields
now contain correct GitHub URLs.
The changes to the HTML manual are all either strict improvements:
* "Declared by:" links point to the correct URLs.
* `lib.mdDoc` documentation is included.
or else trivial:
* Additional whitespace in the HTML source.
* Some interchange of `<pre class="programlisting">` and
`<code class="literal">`.
* Fancy quotes used in some type descriptions.
`optionsDocBook` is exported temporarily as it is used by
`nix-doc-munge` for the Markdown conversion process.
This drops support for building the manual on 22.11, which lacks a
complete implementation of this processor, and provides stubbed-out
manual packages with an explanation on that version.
