+# European Union Public Licence V. 1.1
+
+
+EUPL © the European Community 2007
+
+
+This European Union Public Licence (the “EUPL”) applies to the Work or Software
+(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 Original 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 Original Work:
+
+Licensed under the EUPL V.1.1
+
+or has expressed by any other mean 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 or the Software: the software distributed and/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 and/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 and/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
+ Software under the terms of the Licence.
+
+- Distribution and/or Communication: any act of selling, giving, lending,
+ renting, distributing, communicating, transmitting, or otherwise making
+ available, on-line or off-line, 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 world-wide, royalty-free, non-exclusive,
+sub-licensable 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 Original 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, sub-license 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 and/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
+Original Work or Software, 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 and/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 and/or communicates copies of the
+Original Works or Derivative Works based upon the Original Work, this
+Distribution and/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. 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 and/or Communicates Derivative
+Works or copies thereof based upon both the Original Work and another work
+licensed under a Compatible Licence, this Distribution and/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 and/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 and/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 software 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 Original Work or Derivative Works, You may choose to
+conclude an additional agreement to offer, and charge a fee for, acceptance of
+support, warranty, indemnity, or other liability obligations and/or services
+consistent with this Licence. However, in accepting such 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 such 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 and/or Communication by You of the Work or copies thereof.
+
+
+
+## 11. Information to the public
+
+In case of any Distribution and/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 licensed hereunder.
+
+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 and/or reformed so as necessary to make
+it valid and enforceable.
+
+The European Commission may publish other linguistic versions and/or new
+versions of this Licence, 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
+
+Any litigation resulting from the interpretation of this License, arising
+between the European Commission, as a Licensor, and any Licensee, will be
+subject to the jurisdiction of the Court of Justice of the European Communities,
+as laid down in article 238 of the Treaty establishing the European Community.
+
+Any litigation arising between Parties, other than the European Commission, 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
+
+This Licence shall be governed by the law of the European Union country where
+the Licensor resides or has his registered office.
+
+This licence shall be governed by the Belgian law if:
+
+- a litigation arises between the European Commission, as a Licensor, and any
+- Licensee; the Licensor, other than the European Commission, has no residence
+- or registered office inside a European Union country.
+
+
+
+## Appendix
+
+
+
+“Compatible Licences” according to article 5 EUPL are:
+
+
+- GNU General Public License (GNU GPL) v. 2
+
