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.
