EUROPEAN UNION PUBLIC LICENCE v. 1.2
-------------------------------------
EUPL © the European Union 2007, 2016

This European Union Public Licence (the ‘EUPL’) applies to the Work (as
defined below) which is provided under the terms of this Licence. Any
use of the Work, other than as authorised under this Licence is
prohibited (to the extent such use is covered by a right of the
copyright holder of the Work).

The Work is provided under the terms of this Licence when the Licensor
(as defined below) has placed the following notice immediately following
the copyright notice for the Work:

       Licensed under the EUPL

or has expressed by any other means his willingness to license under the
EUPL.

1. Definitions
~~~~~~~~~~~~~~~~~~~~~~~~~

In this Licence, the following terms have the following meaning:

-  ‘The Licence’: this Licence.

-  ‘The Original Work’: the work or software distributed or communicated
   by the Licensor under this Licence, available as Source Code and also
   as Executable Code as the case may be.

-  ‘Derivative Works’: the works or software that could be created by
   the Licensee, based upon the Original Work or modifications thereof.
   This Licence does not define the extent of modification or dependence
   on the Original Work required in order to classify a work as a
   Derivative Work; this extent is determined by copyright law
   applicable in the country mentioned in Article 15.

-  ‘The Work’: the Original Work or its Derivative Works.

-  ‘The Source Code’: the human-readable form of the Work which is the
   most convenient for people to study and modify.

-  ‘The Executable Code’: any code which has generally been compiled and
   which is meant to be interpreted by a computer as a program.

-  ‘The Licensor’: the natural or legal person that distributes or
   communicates the Work under the Licence.

-  ‘Contributor(s)’: any natural or legal person who modifies the Work
   under the Licence, or otherwise contributes to the creation of a
   Derivative Work.

-  ‘The Licensee’ or ‘You’: any natural or legal person who makes any
   usage of the Work under the terms of the Licence.

-  ‘Distribution’ or ‘Communication’: any act of selling, giving,
   lending, renting, distributing, communicating, transmitting, or
   otherwise making available, online or offline, copies of the Work or
   providing access to its essential functionalities at the disposal of
   any other natural or legal person.

2. Scope of the rights granted by the Licence
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

The Licensor hereby grants You a worldwide, royalty-free, non-exclusive,
sublicensable licence to do the following, for the duration of copyright
vested in the Original Work:

-  use the Work in any circumstance and for all usage,
-  reproduce the Work,
-  modify the Work, and make Derivative Works based upon the Work,
-  communicate to the public, including the right to make available or
   display the Work or copies thereof to the public and perform
   publicly, as the case may be, the Work,
-  distribute the Work or copies thereof,
-  lend and rent the Work or copies thereof,
-  sublicense rights in the Work or copies thereof.

Those rights can be exercised on any media, supports and formats,
whether now known or later invented, as far as the applicable law
permits so.

In the countries where moral rights apply, the Licensor waives his right
to exercise his moral right to the extent allowed by law in order to
make effective the licence of the economic rights here above listed.

The Licensor grants to the Licensee royalty-free, non-exclusive usage
rights to any patents held by the Licensor, to the extent necessary to
make use of the rights granted on the Work under this Licence.

3. Communication of the Source Code
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

The Licensor may provide the Work either in its Source Code form, or as
Executable Code. If the Work is provided as Executable Code, the
Licensor provides in addition a machine-readable copy of the Source Code
of the Work along with each copy of the Work that the Licensor
distributes or indicates, in a notice following the copyright notice
attached to the Work, a repository where the Source Code is easily and
freely accessible for as long as the Licensor continues to distribute or
communicate the Work.

4. Limitations on copyright
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Nothing in this Licence is intended to deprive the Licensee of the
benefits from any exception or limitation to the exclusive rights of the
rights owners in the Work, of the exhaustion of those rights or of other
applicable limitations thereto.

5. Obligations of the Licensee
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

The grant of the rights mentioned above is subject to some restrictions
and obligations imposed on the Licensee. Those obligations are the
following:

Attribution right: The Licensee shall keep intact all copyright, patent
or trademarks notices and all notices that refer to the Licence and to
the disclaimer of warranties. The Licensee must include a copy of such
notices and a copy of the Licence with every copy of the Work he/she
distributes or communicates. The Licensee must cause any Derivative Work
to carry prominent notices stating that the Work has been modified and
the date of modification.

Copyleft clause: If the Licensee distributes or communicates copies of
the Original Works or Derivative Works, this Distribution or
Communication will be done under the terms of this Licence or of a later
version of this Licence unless the Original Work is expressly
distributed only under this version of the Licence — for example by
communicating ‘EUPL v. 1.2 only’. The Licensee (becoming Licensor)
cannot offer or impose any additional terms or conditions on the Work or
Derivative Work that alter or restrict the terms of the Licence.

Compatibility clause: If the Licensee Distributes or Communicates
Derivative Works or copies thereof based upon both the Work and another
work licensed under a Compatible Licence, this Distribution or
Communication can be done under the terms of this Compatible Licence.
For the sake of this clause, ‘Compatible Licence’ refers to the licences
listed in the appendix attached to this Licence. Should the Licensee’s
obligations under the Compatible Licence conflict with his/her
obligations under this Licence, the obligations of the Compatible
Licence shall prevail.

Provision of Source Code: When distributing or communicating copies of
the Work, the Licensee will provide a machine-readable copy of the
Source Code or indicate a repository where this Source will be easily
and freely available for as long as the Licensee continues to distribute
or communicate the Work.

Legal Protection: This Licence does not grant permission to use the
trade names, trademarks, service marks, or names of the Licensor, except
as required for reasonable and customary use in describing the origin of
the Work and reproducing the content of the copyright notice.

6. Chain of Authorship
~~~~~~~~~~~~~~~~~~~~~~~~~

The original Licensor warrants that the copyright in the Original Work
granted hereunder is owned by him/her or licensed to him/her and that
he/she has the power and authority to grant the Licence.

Each Contributor warrants that the copyright in the modifications he/she
brings to the Work are owned by him/her or licensed to him/her and that
he/she has the power and authority to grant the Licence.

Each time You accept the Licence, the original Licensor and subsequent
Contributors grant You a licence to their contributions to the Work,
under the terms of this Licence.

7. Disclaimer of Warranty
~~~~~~~~~~~~~~~~~~~~~~~~~

The Work is a work in progress, which is continuously improved by
numerous Contributors. It is not a finished work and may therefore
contain defects or ‘bugs’ inherent to this type of development.

For the above reason, the Work is provided under the Licence on an ‘as
is’ basis and without warranties of any kind concerning the Work,
including without limitation merchantability, fitness for a particular
purpose, absence of defects or errors, accuracy, non-infringement of
intellectual property rights other than copyright as stated in Article 6
of this Licence.

This disclaimer of warranty is an essential part of the Licence and a
condition for the grant of any rights to the Work.

8. Disclaimer of Liability
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Except in the cases of wilful misconduct or damages directly caused to
natural persons, the Licensor will in no event be liable for any direct
or indirect, material or moral, damages of any kind, arising out of the
Licence or of the use of the Work, including without limitation, damages
for loss of goodwill, work stoppage, computer failure or malfunction,
loss of data or any commercial damage, even if the Licensor has been
advised of the possibility of such damage. However, the Licensor will be
liable under statutory product liability laws as far such laws apply to
the Work.

9. Additional agreements
~~~~~~~~~~~~~~~~~~~~~~~~~

While distributing the Work, You may choose to conclude an additional
agreement, defining obligations or services consistent with this
Licence. However, if accepting obligations, You may act only on your own
behalf and on your sole responsibility, not on behalf of the original
Licensor or any other Contributor, and only if You agree to indemnify,
defend, and hold each Contributor harmless for any liability incurred
by, or claims asserted against such Contributor by the fact You have
accepted any warranty or additional liability.

10. Acceptance of the Licence
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

The provisions of this Licence can be accepted by clicking on an icon ‘I
agree’ placed under the bottom of a window displaying the text of this
Licence or by affirming consent in any other similar way, in accordance
with the rules of applicable law. Clicking on that icon indicates your
clear and irrevocable acceptance of this Licence and all of its terms
and conditions.

Similarly, you irrevocably accept this Licence and all of its terms and
conditions by exercising any rights granted to You by Article 2 of this
Licence, such as the use of the Work, the creation by You of a
Derivative Work or the Distribution or Communication by You of the Work
or copies thereof.

11. Information to the public
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

In case of any Distribution or Communication of the Work by means of
electronic communication by You (for example, by offering to download
the Work from a remote location) the distribution channel or media (for
example, a website) must at least provide to the public the information
requested by the applicable law regarding the Licensor, the Licence and
the way it may be accessible, concluded, stored and reproduced by the
Licensee.

12. Termination of the Licence
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

The Licence and the rights granted hereunder will terminate
automatically upon any breach by the Licensee of the terms of the
Licence.

Such a termination will not terminate the licences of any person who has
received the Work from the Licensee under the Licence, provided such
persons remain in full compliance with the Licence.

13. Miscellaneous
~~~~~~~~~~~~~~~~~~~~~~~~~

Without prejudice of Article 9 above, the Licence represents the
complete agreement between the Parties as to the Work.

If any provision of the Licence is invalid or unenforceable under
applicable law, this will not affect the validity or enforceability of
the Licence as a whole. Such provision will be construed or reformed so
as necessary to make it valid and enforceable.

The European Commission may publish other linguistic versions or new
versions of this Licence or updated versions of the Appendix, so far
this is required and reasonable, without reducing the scope of the
rights granted by the Licence. New versions of the Licence will be
published with a unique version number.

All linguistic versions of this Licence, approved by the European
Commission, have identical value. Parties can take advantage of the
linguistic version of their choice.

14. Jurisdiction
~~~~~~~~~~~~~~~~~~~~~~~~~

Without prejudice to specific agreement between parties,

-  any litigation resulting from the interpretation of this License,
   arising between the European Union institutions, bodies, offices or
   agencies, as a Licensor, and any Licensee, will be subject to the
   jurisdiction of the Court of Justice of the European Union, as laid
   down in article 272 of the Treaty on the Functioning of the European
   Union,

-  any litigation arising between other parties and resulting from the
   interpretation of this License, will be subject to the exclusive
   jurisdiction of the competent court where the Licensor resides or
   conducts its primary business.

15. Applicable Law
~~~~~~~~~~~~~~~~~~~~~~~~~

Without prejudice to specific agreement between parties,

-  this Licence shall be governed by the law of the European Union
   Member State where the Licensor has his seat, resides or has his
   registered office,

-  this licence shall be governed by Belgian law if the Licensor has no
   seat, residence or registered office inside a European Union Member
   State.
