Improve beam docs:
* correct spelling
* update per pandoc changes
* capitalize titles
* capitalize BEAM throughout and use "the BEAM" when referring to the virtual machine.
* tweak grammar and phrasing
* reformat build-tools-rebar3 section
* add more links
* re-wrap <para>s
Also update <programlisting>s
* normalize whitespace
* don't double quote homepage
* use $ in all shell snippets
The documentation got a bit stale compared to actual contents of
nixpkgs. This commit focuses on updating existing docs, not on making
sure all details of beam packages are covered.
* Update python.md
this makes it clear how to alter `attributes` by using `packageOverrides`
* Update python.md
* Update python.md
* Update python.md
* Update python.md
* Update python.md
* Update python.md
Fix code syntax highlighting by specifying language in every code block
and adding some context to Nix code blocks to make them valid
expressions. Use the same markup style for all code blocks. Reformat
some code blocks.

- Describe the new `libsForQt5.callPackage` interface
- Emphasize that Qt dependencies must be imported unqualified
- Describe the new `kdeWrapper` wrapper generator
If the flag enableIntegerSimple is true GHC will be build with the GPL-free but
slower integer-simple library instead of the faster but GPLed integer-gmp
library.
The attribute `pkgs.haskell.compiler.integer-simple."${ghcVersion}"` provides a
GHC compiler build with `integer-simple`.
Similarly, the attribute `pkgs.haskell.packages.integer-simple."${ghcVersion}"`
provides a package set supporting `integer-simple`.

This patch add a new argument to Nixpkgs default expression named "overlays".
By default, the value of the argument is either taken from the environment variable `NIXPKGS_OVERLAYS`,
or from the directory `~/.nixpkgs/overlays/`. If the environment variable does not name a valid directory
then this mechanism would fallback on the home directory. If the home directory does not exists it will
fallback on an empty list of overlays.
The overlays directory should contain the list of extra Nixpkgs stages which would be used to extend the
content of Nixpkgs, with additional set of packages. The overlays, i-e directory, files, symbolic links
are used in alphabetical order.
The simplest overlay which extends Nixpkgs with nothing looks like:
```nix
self: super: {
}
```
More refined overlays can use `super` as the basis for building new packages, and `self` as a way to query
the final result of the fix-point.
An example of overlay which extends Nixpkgs with a small set of packages can be found at:
https://github.com/nbp/nixpkgs-mozilla/blob/nixpkgs-overlay/moz-overlay.nix
To use this file, checkout the repository and add a symbolic link to
the `moz-overlay.nix` file in `~/.nixpkgs/overlays` directory.
I wanted to list the different texlive collections using the nix-repl, as per the [manual](https://nixos.org/nixpkgs/manual/#idm140737316065984).
It didn't work, since the nixpkgs were not loaded. Doing `:l <nixpkgs>` first resolved the problem.
This change adds the nixpkgs loading step to the manual so that the next inexperienced person don't have to figure out why it didn't work.
I tested this on NixOS unstable (16.09pre90254.6b20d5b) with nix-repl 1.11.3.
In #19309 a separate output for tkinter was added.
Several dependencies of Python depend indirectly on Python. We have the
following two paths:
```
‘python-2.7.12’ - ‘tk-8.6.6’ - ‘libXft-2.3.2’ - ‘libXrender-0.9.10’ -
‘libX11-1.6.4’ - ‘libxcb-1.12’ - ‘libxslt-1.1.29’- ‘libxml2-2.9.4’ -
‘python-2.7.12’
‘python-2.7.12’ - ‘tk-8.6.6’ - ‘libXft-2.3.2’ - ‘fontconfig-2.12.1’ -
‘dejavu-fonts-2.37’ - ‘fontforge-20160404’ - ‘python-2.7.12’
```
Because only `tkinter` needs this, I added
```
pythonSmall = python.override {x11Support = false;};
```
to break the infinite recursion. We also still have the output
`tkinter`.
However, we might as well build without x11Support by default. Then we build with x11Support as well so we get the tkinter module and put that in a separate package.
After #16017 there were a lot
of comments saying that `nix` would be better than `JSON`
for Go packages dependency sets.
As said in https://github.com/NixOS/nixpkgs/pull/16017#issuecomment-229624046

This PR removes `libs.json` file and puts all package dependencies in
theirs `deps.json`.
- missing cd command
- invoke bundler through nix-shell, so it doesn't need to be on $PATH
Note: running bundix through nix-shell won't work ATM, as the shell sets
SSL_CERT_FILE=/no-cert-file.crt which prevents fetching throug https.
- use version from gemset to simplify updating
- don't break line in meta.description
There's no change in content except for amending the title of the
section to mention "frameworks", as e.g. I don't consider Qt a language,
and it's likely there will be more of similar cases in future.
To be certain, I checked diff of the generated HTMLs.
