EUPL © the European Community 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.
