Antoine Vandevenne (anv) e3fee2cf46 [REF][MOV] documentation apocalypse
Prior to this commit, the Odoo documentation was mainly split between
two repositories: odoo/odoo/doc and odoo/documentation-user. Some bits
of documentation were also hosted elsewhere (e.g., wiki, upgrade, ...).
This was causing several problems among which:
  - The theme, config, Makefile, and similar technical resources had to
    be duplicated. This resulted in inconsistent layout, features, and
    build environments from one documentation to another.
  - Some pages did not fit either documentation as they were relevant
    for both users and developers. Some were relevant to neither of the
    two (e.g., DB management).
  - Cross-doc references had to be absolute links and they broke often.
  - Merging large image files in the developer documentation would bloat
    the odoo/odoo repository. Some contributions had to be lightened to
    avoid merging too many images (e.g., Odoo development tutorials).
  - Long-time contributors to the user documentation were chilly about
    going through the merging process of the developer documentation
    because of the runbot, mergebot, `odoo-dev` repository, etc.
  - Some contributors would look for the developer documentation in the
    `odoo/documentation-user` repository.
  - Community issues about the user documentation were submitted on the
    `odoo/odoo` repository and vice-versa.

Merging all documentations in one repository will allow us to have one
place, one theme, one work process, and one set of tools (build
environment, ...) for all of the Odoo docs.

As this is a good opportunity to revamp the layout of the documentation,
a brand new theme replaces the old one. It features a new way to
navigate the documentation, centered on the idea of always letting the
reader know what is the context (enclosing section, child pages, page
structure ...) of the page they are reading. The previous theme would
quickly confuse readers as they navigated the documentation and followed
cross-application links.

The chance is also taken to get rid of all the technical dangling parts,
performance issues, and left-overs. Except for some page-specific JS
scripts, the Odoo theme Sphinx extension is re-written from scratch
based on the latest Sphinx release to benefit from the improvements and
ease future contributions.

===================================================
Setting up the Fiscal Data Module with the Odoo POS
===================================================
Introduction
============
The Belgian government requires certain businesses to use a
government-certified device called a **Fiscal Data Module** (also
known as a **blackbox**). This device works together with the POS
application and logs certain transactions. On top of that, the used
POS application must also be certified by the government and must
adhere to strict standards specified by them. `Odoo 9 (Enterprise Edition) is a
certified application
<http://www.systemedecaisseenregistreuse.be/systemes-certifies>`_. More
information concerning the Fiscal Data Module can be found on `the
official website <http://www.systemedecaisseenregistreuse.be/>`_.
Required hardware
=================
* A government certified `Fiscal Data Module
<http://www.systemedecaisseenregistreuse.be/systemes-certifies#FDM%20certifiés>`_
per POS, all of them should work, but the Cleancash SC-B is
recommended, you will also need:
* Serial null modem cable per FDM (`example
<http://www.startech.com/Cables/Serial-Parallel-PS-2/DB9-DB25/10-ft-Cross-Wired-Serial-Null-Modem-Cable-DB9-FM~SCNM9FM>`__)
* Serial-to-USB adapter per FDM (`example
<http://trendnet.com/products/proddetail.asp?prod=265_TU-S9>`__)
* A registered IoT Box per POS configuration
Setup
=====
IoT Box
-------
In order to use a Fiscal Data Module, you will need a registered
IoT Box. These IoT Boxes are similar to the regular IoT Boxes we sell,
but they are registered with the Belgian government. This is required
by law. Attempting to use a Fiscal Data Module on a non-registered
IoT Box will not work. You can verify that the Fiscal Data Module is
recognized by the IoT Box by going to the *Hardware status page* via
the IoT Box homepage.

Odoo
----
An Odoo POS app can be given certified POS capabilities by installing
the **Belgian Registered Cash Register** app (technical name:
``pos_blackbox_be``). Because of government restrictions imposed on
us, this installation cannot be undone. After this, you will have to
ensure that each POS configuration has a unique registered IoT Box
associated with it (:menuselection:`Point of Sale --> Configuration
--> Point of Sale` and ensure Hardware Proxy / IoT Box and the serial
number of your IoT Box is set). The first time you open the Point of
Sale and attempt to do a transaction, you will be asked to input the
PIN that you received with your VAT signing card.

Certification & On-premise
==========================
The certification granted by the government is restricted to the use on odoo.com
SaaS instance. The usage of the module from the source or a modified version
will **not** be certified. For on-premise users, we also support the Fiscal Data
Module in such installations. The main restriction is that this requires an
obfuscated version of the ``pos_blackbox_be`` module we will provide on request
for Enterprise customers.
Restrictions
============
As mentioned before, in order to get certified the POS application
must adhere to strict government guidelines. Because of this, a
certified Odoo POS has some limitations not present in the
non-certified Odoo POS.
* Refunding is disabled
* Modifying orderline prices
* Creating/modifying/deleting POS orders
* Selling products without a valid tax
* Multiple Odoo POS configurations per IoT Box are not allowed
* Using the POS without a connection to the IoT Box (and thus FDM)
* Blacklisted modules: pos_discount, pos_reprint, pos_loyalty
