docs: drop options.md from the repository
Generate the file on the readthedocs builder using Nix. Since there is
no root access or user namespaces, we have to use proot (see
https://nixos.wiki/wiki/Nix_Installation_Guide#PRoot).

Run NixOS tests
---------------
To run the test suite, you need to enable `Nix Flakes
<https://nixos.wiki/wiki/Flakes#Installing_flakes>`_.
You can then run the testsuite via
::
$ nix flake check -L
Since Nix doesn't garantee your machine have enough resources to run
all test VMs in parallel, some tests can fail. You would then haev to
run tests manually. For instance:
::
$ nix build .#hydraJobs.x86_64-linux.external-unstable -L
Contributing to the documentation
---------------------------------
The documentation is written in RST (except option documentation which is in CommonMark),
built with Sphinx and published by `Read the Docs <https://readthedocs.org/>`_.
For the syntax, see the `RST/Sphinx primer
<https://www.sphinx-doc.org/en/master/usage/restructuredtext/basics.html>`_.
To build the documentation, you need to enable `Nix Flakes
<https://nixos.wiki/wiki/Flakes#Installing_flakes>`_.
::
$ nix build .#documentation
$ xdg-open result/index.html
Nixops
------
You can test the setup via ``nixops``. After installation, do
::
$ nixops create nixops/single-server.nix nixops/vbox.nix -d mail
$ nixops deploy -d mail
$ nixops info -d mail
You can then test the server via e.g. \ ``telnet``. To log into it, use
::
$ nixops ssh -d mail mailserver
Imap
----
To test imap manually use
::
$ openssl s_client -host mail.example.com -port 143 -starttls imap
