The text was originally added [0] following an apparently incomplete
research on how everything plays together. In fact, Nix propagates
`outputs` to the corresponding nested derivations, and there is some
messy behavior in Nixpkgs that only seems to propagate
`meta.outputsToInstall` in `buildEnv`[1].
This change moves the hints on how to use NixOS specifics to NixOS
module documentation (which is hopefully easier to find through
search.nixos.org), describes the default behavior in Nixpkgs (updating
a the link to the source), and removes the confusing mention of
`nix-env`.
the last of them should not be there to begin with. we don't want
beginners to use `nix-env`, as this is known to run them into trouble
eventually.

>> 3: Discourage using package sets like python3.pkgs "directly"
> I think about 8 years ago I introduced this and it has been a clear mistake. Since then this pattern was copied throughout. We should indeed go to pythonPackages and also move the helpers such as buildEnv and withPackages into the package set, like haskell already had before.

Clarify that the monochrome font is not included, per #221181.
The new name is also coherent with the name of the font,
according to `fontconfig`: Noto Color Emoji.
This change which involves creating multiple outputs for CUDA
redistributable packages.
We use a script to find out, ahead of time, the outputs each redist
package provides. From that, we are able to create multiple outputs for
supported redist packages, allowing users to specify exactly which
components they require.
Beyond the script which finds outputs ahead of time, there is some custom
code involved in making this happen. For example, the way Nixpkgs
typically handles multiple outputs involves making `dev` the default
output when available, and adding `out` to `dev`'s
`propagatedBuildInputs`.
Instead, we make each output independent of the others. If a user wants
only to include the headers found in a redist package, they can do so by
choosing the `dev` output. If they want to include dynamic libraries,
they can do so by specifying the `lib` output, or `static` for static
libraries.
To avoid breakages, we continue to provide the `out` output, which
becomes the union of all other outputs, effectively making the split
outputs opt-in.
1. Clarify what is the reason for importing and to where it saves
2. Clarify that packages.sqlite is a temporary file
3. Link to section about native dependencies from first mention of ql.nix
Add this hook to checkPhase to allow for running MPI application in
the sandbox. It detects the MPI implementations and sets the respective

Zig is still under active development, and new releases often introduce
breaking changes. This makes updating the default version of zig easier.
Some packages did not receive this change because they could be using
the c compiler or linker of zig, which doesn't receive as much breaking
changes compared to e.g. the zig std library.

This is very useful in conjunction with meta.pkgConfigModules, as the
new tester can use the list provided by this meta attribute as a default
value for moduleNames, making its usage in passthru.tests very
convenient.
For backwards compatibility, a shim under the old name is maintained
with a warning.
* nixpkgs manual, doc Python: render interpreters in a table
The current paragraph presenting Python interpreters is verbose and hinders clarity. The information provided is well suited to be rendered as a table.

I had to change ${go-modules} to $goModules to allow overrideAttrs to work;
However, env vars cannot contain -, so i had to change go-modules too.
This in turn broke nix-update because it uses the go-modules attr.
Instead of making nix-update more complicated, make go-modules naming match cargoDeps.

release note added
separating function docs out like this makes it less clear how library
documentation is generated and integrated into the build. if in the
future more parts of nixpkgs use nixdoc it will make sense to have all
information about library doc generation in the same place.
all xml-related tooling can go away. shell.nix is no longer useful since
the makefile is gone and the build runs entirely via a derivation, and
gitignore is thus also no longer that useful. it may filter out some
swap files, but its main reason to exist (keeping generated files out of
a concurrent build of the derivation) has gone away.
also updates nixdoc to 2.3.0. the nixdoc update is not a separate commit
because that would leave the manual build broken for one commit,
potentially breaking bisects and rebases.
nothing except function docs uses this, so we need not expose it. we'll
be reworking this entire section of the build anyway, with the target of
breaking up doc-support as it is now.
Makes overrideAttrs usable in the same way that `override` can be used.
It allows the first argument of `overrideAttrs` to be either a function
or an attrset, instead of only a function:
hello.overrideAttrs (old: { postBuild = "echo hello"; })
hello.overrideAttrs { postBuild = "echo hello"; }
Previously only the first example was possible.

This is actually relatively complicated to achieve, since it involves
overriding GHC on e.g. aarch64-darwin, so the FAQ entry seems warranted.
It's also a good exercise to me, since it demonstrates some problems
with the overriding infrastructure, i.e. that it has a tendency to
inherit the pkgs fixpoint from prev. An example of this problem is
https://github.com/NixOS/nixpkgs/issues/235960, but it has different
manifestations as well. Awareness of this will also help writing the
other sections on overriding.
How complicated it is, seems to be further incentive to go ahead with
https://github.com/NixOS/nixpkgs/pull/239548 as well.
This reverts commit 7e6c518ce4.
I misinterpreted Github's CI failure in the notification tab and
thought that I had broken CI on origin/master, so I panic-reverted
before I merged it (I thought they had).
On closer inspection, it appears that the CI failure was not from
the tip that I merged. This PR resubmits the reverted change. I'll
wait for OfBorg to finish this time.
The manual does an okay job of explaining the rules for each of the
three development branches, but really doesn't give any intuition as
to why there are three (why not four? or two?) or how we got where
we are today.
This commit attempts to fix that, by explaining that there is one
branch that allows mass-rebuild commits, and it has a fast-building
branch both upstream and downstream of it (from the perspective of
automated merges).
I have also removed the term "stabilization" from the arc labels.
This vague term is not defined anywhere, and does communicate any
useful information without a longer explanation. Therefore it is
not appropriate for use in a diagram.

It may have to be fetchpatch, fetchpatch2, or fetchurl. We should link somewhere, but we don't have a link target yet, so until then, remove the inaccurate info.
