+                      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.
+
+Appendix
