Cette licence est basée sur "Cecill".
En apposant cette licence à un logiciel, sa copie, sa diffusion, en tout ou en partie, de même que son exécution, sont soumises aux termes de la licence.
Le texte est rédigé dans un langage juridique et ses détails sont tous importants pour sa cohérence, cependant il est assez bien résumé en quatre phrases courtes : (1) Le logiciel est en libre accès. (2) Une communauté d'utilisateurs potentiels est définie, engagée dans un mode de vie soutenable ou un processus de redirection écologique. (3) Pour cette communauté d'utilisateur, les termes d'une licence libre s'appliquent. (4) En dehors de cette communauté, toute utilisation, copie, modification, diffusion est prohibée.
Le texte de la licence est uniquement écrit en Anglais pour l'instant. Pour l'adopter, il suffit de le mentionner sur la page où vous rendez le logiciel accessible, en en-tête des fichiers de code, ou dans le répertoire principal de votre code, dans un fichier nommé par exemple "license.txt". Un résumé explique en langage humain les droits et les devoirs associés, puis le texte juridique suit.
En acceptant les terme de cette licence, vous obtenez le droit de :

In this respect, the Licensee's attention has been drawn to the risks associated with loading, using, modifying and/or developing and reproducing the Software which are reserved for experienced users.
The Licensee shall be responsible for verifying, by any or all means, the suitability of the product for its requirements, its good working order, and for ensuring that it shall not cause damage to either persons or properties.

9.4 The Licensor does not either expressly or tacitly warrant that the Software does not infringe any third party intellectual property right relating to a patent, software or any other property right.

10.2 A Licensee whose Agreement is terminated shall no longer be authorized to use, modify or distribute the Software. However, any licenses that it may have granted prior to termination of the Agreement shall remain valid subject to their having been granted in compliance with the terms and conditions hereof.
11.1 EXCUSABLE EVENTS Neither Party shall be liable for any or all delay, or failure to perform the Agreement, that may be attributable to an event of force majeure, or an outside cause, such as defective functioning or interruptions of the electricity or telecommunications networks, network paralysis following a virus attack, intervention by government authorities, natural disasters, water damage, earthquakes, fire, explosions, strikes and labor unrest, war, etc.

11.3 The Agreement cancels and replaces any or all previous agreements, whether written or oral, between the Parties and having the same purpose, and constitutes the entirety of the agreement between said Parties concerning said purpose. No supplement or modification to the terms and conditions hereof shall be effective as between the Parties unless it is made in writing and signed by their duly authorized representatives.
11.4 In the event that one or more of the provisions hereof were to conflict with a current or future applicable act or legislative text, said act or legislative text shall prevail, and the Parties shall make the necessary amendments so as to comply with said act or legislative text. All other provisions shall remain effective. Similarly, invalidity of a provision of the Agreement, for any reason whatsoever, shall not cause the Agreement as a whole to be invalid.
