1. Use the same approach like in the overlay example:
Override `python` instead of `pythonPackages` so that
`python.pkgs` refers to the new package set like `pythonPackages`.
This also fixes a bug in the original example where
`pkgs.fetchgit` was not in scope.
Add an extra example to illustrate how to override just a
package set.
2. Fix mix-up between `super` and `self` in the explanation text.
Also, simplify the explanation.
This makes the command ‘nix-env -qa -f. --arg config '{skipAliases =
true;}'’ work in Nixpkgs.

- qtikz: use libsForQt5.callPackage
This ensures we get the right poppler.
- rewrites:
docbook5_xsl -> docbook_xsl_ns
docbook_xml_xslt -> docbook_xsl
diffpdf: fixup
This script is used to automatically fix issues within xml documentation
files.
The script is *for now* intended to be used ad-hoc, and the commits to
be examined.
A future discussion will define whether:
* This commit and scripts are kept.
* The script is extended for common use.
The biggest issue right now with the script is that it *could* in theory
destroy a valid space-less varlistentry.
The script could, in practical use, be changed and extended to normalize
some parts of the XML files, mainly:
* A common quoting style for attributes
* Fix-up some weird formatting automatically that xmlformat doesn't
catch
This fixes a regression introduced in 4b06383.

Relevant section: 9.5.2.3. How to install a compiler with libraries, hoogle and documentation indexes
Since version 5 `hoogle server`s --local flag solves the problem with links from
`http:` to `file:` URIs:
hoogle server --local -p 8080
As suggested in https://github.com/NixOS/nixpkgs/pull/39416#discussion_r183845745
the versioning attributes in `lib` should be consistent to
`nixos/version` which implicates the following changes:
* `lib.trivial.version` -> `lib.trivial.release`
* `lib.trivial.suffix` -> `lib.trivial.versionSuffix`
* `lib.nixpkgsVersion` -> `lib.version`
As `lib.nixpkgsVersion` is referenced several times in `NixOS/nixpkgs`,
`NixOS/nix` and probably several user's setups. As the rename will cause
a notable impact it's better to keep `lib.nixpkgsVersion` as alias with
a warning yielded by `builtins.trace`.
Note that a bunch of non-python packages use this attribute already.
Some of those are clearly unaware of the fact that this attribute does
not exists in stdenv because they define it but don't to add it to
their `bulidInputs` :)
Also note that I use `buildInputs` here and only handle regular
builds because python and haskell builders do it this way and I'm not
sure how to properly handle the cross-compilation case.
Setting haskell.packageOverrides like so:
haskell = super.haskell // {
packageOverrides = self: super: {
my-package = ...;
my-other-package = ...;
};
};
causes all compiler-specific package sets to be overridden with those
overrides.
