+OPEN-SOURCE-LIZENZ FÜR DIE EUROPÄISCHE UNION v. 1.2 
+EUPL © Europäische Union 2007, 2016 
+Diese Open-Source-Lizenz für die Europäische Union („EUPL“) gilt für Werke (im Sinne der nachfolgenden Begriffsbestimmung), die unter EUPL-Bedingungen zur Verfügung gestellt werden. Das Werk darf nur in der durch diese Lizenz gestatteten Form genutzt werden (insoweit eine solche Nutzung dem Urheber vorbehalten ist). 
+Das Werk wird unter den Bedingungen dieser Lizenz zur Verfügung gestellt, wenn der Lizenzgeber (im Sinne der nachfolgenden Begriffsbestimmung) den folgenden Hinweis unmittelbar hinter dem Urheberrechtshinweis dieses Werks anbringt: 
+                      Lizenziert unter der EUPL 
+oder in einer anderen Form zum Ausdruck bringt, dass er es unter der EUPL lizenzieren möchte. 
+
+1.Begriffsbestimmungen 
+Für diese Lizenz gelten folgende Begriffsbestimmungen:  
+— „Lizenz“:diese Lizenz.  
+— „Originalwerk“:das Werk oder die Software, die vom Lizenzgeber unter dieser Lizenz verbreitet oder zugänglich gemacht wird, und zwar als Quellcode und gegebenenfalls auch als ausführbarer Code.  
+— „Bearbeitungen“:die Werke oder Software, die der Lizenznehmer auf der Grundlage des Originalwerks oder seiner Bearbeitungen schaffen kann. In dieser Lizenz wird nicht festgelegt, wie umfangreich die Änderung oder wie stark die Abhängigkeit vom Originalwerk für eine Einstufung als Bearbeitung sein muss; dies bestimmt sich nach dem Urheberrecht, das in dem unter Artikel 15 aufgeführten Land anwendbar ist.  
+— „Werk“:das Originalwerk oder seine Bearbeitungen.  
+— „Quellcode“:diejenige Form des Werkes, die zur Auffassung durch den Menschen bestimmt ist und die am besten geeignet ist, um vom Menschen verstanden und verändert zu werden.  
+— „Ausführbarer Code“:die — üblicherweise — kompilierte Form des Werks, die von einem Computer als Programm ausgeführt werden soll.  
+— „Lizenzgeber“:die natürliche oder juristische Person, die das Werk unter der Lizenz verbreitet oder zugänglich macht.  
+— „Bearbeiter“:jede natürliche oder juristische Person, die das Werk unter der Lizenz verändert oder auf andere Weise zur Schaffung einer Bearbeitung beiträgt.  
+— „Lizenznehmer“ („Sie“):jede natürliche oder juristische Person, die das Werk unter den Lizenzbedingungen nutzt.  
+— „Verbreitung“ oder „Zugänglichmachung“:alle Formen von Verkauf, Überlassung, Verleih, Vermietung, Verbreitung, Weitergabe, Übermittlung oder anderweitiger Online- oder Offline-Bereitstellung von Vervielfältigungen des Werks oder Zugänglichmachung seiner wesentlichen Funktionen für dritte natürliche oder juristische Personen.
+
+2.Umfang der Lizenzrechte 
+Der Lizenzgeber erteilt Ihnen hiermit für die Gültigkeitsdauer der am Originalwerk bestehenden Urheberrechte eine weltweite, unentgeltliche, nicht ausschließliche, unterlizenzierbare Lizenz, die Sie berechtigt: 
+—  das Werk uneingeschränkt zu nutzen, 
+—  das Werk zu vervielfältigen, 
+—  das Werk zu verändern und Bearbeitungen auf der Grundlage des Werks zu schaffen, 
+—  das Werk öffentlich zugänglich zu machen, was das Recht einschließt, das Werk oder Vervielfältigungsstücke davon öffentlich bereitzustellen oder wahrnehmbar zu machen oder das Werk, soweit möglich, öffentlich aufzuführen, 
+—  das Werk oder Vervielfältigungen davon zu verbreiten, 
+—  das Werk oder Vervielfältigungen davon zu vermieten oder zu verleihen, 
+—  das Werk oder Vervielfältigungen davon weiter zu lizenzieren. 
+Für die Wahrnehmung dieser Rechte können beliebige, derzeit bekannte oder künftige Medien, Träger und Formate verwendet werden, soweit das geltende Recht dem nicht entgegensteht. Für die Länder, in denen Urheberpersönlichkeitsrechte an dem Werk bestehen, verzichtet der Lizenzgeber im gesetzlich zulässigen Umfang auf seine Urheberpersönlichkeitsrechte, um die Lizenzierung der oben aufgeführten Verwertungsrechte wirksam durchführen zu können. Der Lizenzgeber erteilt dem Lizenznehmer ein nicht ausschließliches, unentgeltliches Nutzungsrecht an seinen Patenten, sofern dies zur Ausübung der durch die Lizenz erteilten Nutzungsrechte am Werk notwendig ist. 
+
+3.Zugänglichmachung des Quellcodes 
+Der Lizenzgeber kann das Werk entweder als Quellcode oder als ausführbaren Code zur Verfügung stellen. Stellt er es als ausführbaren Code zur Verfügung, so stellt er darüber hinaus eine maschinenlesbare Kopie des Quellcodes für jedes von ihm verbreitete Vervielfältigungsstück des Werks zur Verfügung, oder er verweist in einem Vermerk im Anschluss an den dem Werk beigefügten Urheberrechtshinweis auf einen Speicherort, an dem problemlos und unentgeltlich auf den Quellcode zugegriffen werden kann, solange der Lizenzgeber das Werk verbreitet oder zugänglich macht. 
+
+4.Einschränkungen des Urheberrechts
+Es ist nicht Zweck dieser Lizenz, Ausnahmen oder Schranken der ausschließlichen Rechte des Urhebers am Werk, die dem Lizenznehmer zugutekommen, einzuschränken. Auch die Erschöpfung dieser Rechte bleibt von dieser Lizenz unberührt. 
+
+5.Pflichten des Lizenznehmers 
+Die Einräumung der oben genannten Rechte ist an mehrere Beschränkungen und Pflichten für den Lizenznehmer gebunden: 
+
+Urheberrechtshinweis, Lizenztext, Nennung des Bearbeiters: Der Lizenznehmer muss alle Urheberrechts-, Patent- oder Markenrechtshinweise und alle Hinweise auf die Lizenz und den Haftungsausschluss unverändert lassen. Jedem von ihm verbreiteten oder zugänglich gemachten Vervielfältigungsstück des Werks muss der Lizenznehmer diese Hinweise sowie diese Lizenz beifügen. Der Lizenznehmer muss auf jedem abgeleiteten Werk deutlich darauf hinweisen, dass das Werk geändert wurde, und das Datum der Bearbeitung angeben.
+
+„Copyleft“-Klausel: Der Lizenznehmer darf Vervielfältigungen des Originalwerks oder Bearbeitungen nur unter den Bedingungen dieser EUPL oder einer neueren Version dieser Lizenz verbreiten oder zugänglich machen, außer wenn das Originalwerk ausdrücklich nur unter dieser Lizenzversion — z. B. mit der Angabe „Nur EUPL V. 1.2“ — verbreitet werden darf. Der Lizenznehmer (der zum Lizenzgeber wird) darf für das Werk oder die Bearbeitung keine zusätzlichen Bedingungen anbieten oder vorschreiben, die die Bedingungen dieser Lizenz verändern oder einschränken. 
+
+Kompatibilitäts-Klausel: Wenn der Lizenznehmer Bearbeitungen, die auf dem Werk und einem anderen Werk, das unter einer kompatiblen Lizenz lizenziert wurde, basieren, oder die Kopien dieser Bearbeitungen verbreitet oder zugänglich macht, kann dies unter den Bedingungen dieser kompatiblen Lizenz erfolgen. Unter „kompatibler Lizenz“ ist eine im Anhang dieser Lizenz angeführte Lizenz zu verstehen. Sollten die Verpflichtungen des Lizenznehmers aus der kompatiblen Lizenz mit denjenigen aus der vorliegenden Lizenz (EUPL) in Konflikt stehen, werden die Verpflichtungen aus der kompatiblen Lizenz Vorrang haben.
+
+Bereitstellung des Quellcodes: Wenn der Lizenznehmer Vervielfältigungsstücke des Werks verbreitet oder zugänglich macht, muss er eine maschinenlesbare Fassung des Quellcodes mitliefern oder einen Speicherort angeben, über den problemlos und unentgeltlich so lange auf diesen Quellcode zugegriffen werden kann, wie der Lizenznehmer das Werk verbreitet oder zugänglich macht. 
+
+Rechtsschutz: Diese Lizenz erlaubt nicht die Benutzung von Kennzeichen, Marken oder geschützten Namensrechten des Lizenzgebers, soweit dies nicht für die angemessene und übliche Beschreibung der Herkunft des Werks und der inhaltlichen Wiedergabe des Urheberrechtshinweises erforderlich ist.
+
+6.Urheber und Bearbeiter 
+Der ursprüngliche Lizenzgeber gewährleistet, dass er das Urheberrecht am Originalwerk innehat oder dieses an ihn lizenziert wurde und dass er befugt ist, diese Lizenz zu erteilen. 
+Jeder Bearbeiter gewährleistet, dass er das Urheberrecht an den von ihm vorgenommenen Änderungen des Werks besitzt und befugt ist, diese Lizenz zu erteilen. 
+Jedes Mal, wenn Sie die Lizenz annehmen, erteilen Ihnen der ursprüngliche Lizenzgeber und alle folgenden Bearbeiter eine Befugnis zur Nutzung ihrer Beiträge zum Werk unter den Bedingungen dieser Lizenz. 
+
+7.Gewährleistungsausschluss 
+Die Arbeit an diesem Werk wird laufend fortgeführt; es wird durch unzählige Bearbeiter ständig verbessert. Das Werk ist nicht vollendet und kann daher Fehler („bugs“) enthalten, die dieser Art der Entwicklung inhärent sind. 
+Aus den genannten Gründen wird das Werk unter dieser Lizenz „so, wie es ist“ ohne jegliche Gewährleistung zur Verfügung gestellt. Dies gilt unter anderem — aber nicht ausschließlich — für Marktreife, Verwendbarkeit für einen bestimmten Zweck, Mängelfreiheit, Richtigkeit sowie Nichtverletzung von anderen Immaterialgüterrechten als dem Urheberrecht (vgl. dazu Artikel 6 dieser Lizenz). 
+Dieser Gewährleistungsausschluss ist wesentlicher Bestandteil der Lizenz und Bedingung für die Einräumung von Rechten an dem Werk.
+
+8.Haftungsausschluss/Haftungsbeschränkung 
+Außer in Fällen von Vorsatz oder der Verursachung von Personenschäden haftet der Lizenzgeber nicht für direkte oder indirekte, materielle oder immaterielle Schäden irgendwelcher Art, die aus der Lizenz oder der Benutzung des Werks folgen; dies gilt unter anderem, aber nicht ausschließlich, für Firmenwertverluste, Produktionsausfall, Computerausfall oder Computerfehler, Datenverlust oder wirtschaftliche Schäden, und zwar auch dann, wenn der Lizenzgeber auf die Möglichkeit solcher Schäden hingewiesen wurde. Unabhängig davon haftet der Lizenzgeber im Rahmen der gesetzlichen Produkthaftung, soweit die entsprechenden Regelungen auf das Werk anwendbar sind. 
+
+9.Zusatzvereinbarungen 
+Wenn Sie das Werk verbreiten, können Sie Zusatzvereinbarungen schließen, in denen Verpflichtungen oder Dienstleistungen festgelegt werden, die mit dieser Lizenz vereinbar sind. Sie dürfen Verpflichtungen indessen nur in Ihrem eigenen Namen und auf Ihre eigene Verantwortung eingehen, nicht jedoch im Namen des ursprünglichen Lizenzgebers oder eines anderen Bearbeiters, und nur, wenn Sie sich gegenüber allen Bearbeitern verpflichten, sie zu entschädigen, zu verteidigen und von der Haftung freizustellen, falls aufgrund der von Ihnen eingegangenen Gewährleistungsverpflichtung oder Haftungsübernahme Forderungen gegen sie geltend gemacht werden oder eine Haftungsverpflichtung entsteht. 
+
+10.Annahme der Lizenz 
+Sie können den Bestimmungen dieser Lizenz zustimmen, indem Sie das Symbol „Lizenz annehmen“ unter dem Fenster mit dem Lizenztext anklicken oder indem Sie Ihre Zustimmung auf vergleichbare Weise in einer nach anwendbarem Recht zulässigen Form geben. Das Anklicken des Symbols gilt als Anzeichen Ihrer eindeutigen und unwiderruflichen Annahme der Lizenz und der darin enthaltenen Klauseln und Bedingungen. In gleicher Weise gilt als Zeichen der eindeutigen und unwiderruflichen Zustimmung die Ausübung eines Rechtes, das in Artikel 2 dieser Lizenz angeführt ist, wie das Erstellen einer Bearbeitung oder die Verbreitung oder Zugänglichmachung des Werks oder dessen Vervielfältigungen. 
+
+11.Informationspflichten
+Wenn Sie das Werk verbreiten oder zugänglich machen (beispielsweise, indem Sie es zum Herunterladen von einer Website anbieten), müssen Sie über den Vertriebskanal oder das benutzte Verbreitungsmedium der Öffentlichkeit zumindest jene Informationen bereitstellen, die nach dem anwendbaren Recht bezüglich der Lizenzgeber, der Lizenz und ihrer Zugänglichkeit, des Abschlusses des Lizenzvertrags sowie darüber, wie die Lizenz durch den Lizenznehmer gespeichert und vervielfältigt werden kann, erforderlich sind.
+
+12.Beendigung der Lizenz 
+Die Lizenz und die damit eingeräumten Rechte erlöschen automatisch, wenn der Lizenznehmer gegen die Lizenzbedingungen verstößt. Ein solches Erlöschen der Lizenz führt nicht zum Erlöschen der Lizenzen von Personen, denen das Werk vom Lizenznehmer unter dieser Lizenz zur Verfügung gestellt worden ist, solange diese Personen die Lizenzbedingungen erfüllen. 
+13.Sonstiges
+Unbeschadet des Artikels 9 stellt die Lizenz die vollständige Vereinbarung der Parteien über das Werk dar. Sind einzelne Bestimmungen der Lizenz nach geltendem Recht nichtig oder unwirksam, so berührt dies nicht die Wirksamkeit oder Durchsetzbarkeit der Lizenz an sich. Solche Bestimmungen werden vielmehr so ausgelegt oder modifiziert, dass sie wirksam und durchsetzbar sind. Die Europäische Kommission kann weitere Sprachfassungen oder neue Versionen dieser Lizenz oder aktualisierte Fassungen des Anhangs veröffentlichen, soweit dies notwendig und angemessen ist, ohne den Umfang der Lizenzrechte zu verringern. Neue Versionen werden mit einer eindeutigen Versionsnummer veröffentlicht. Alle von der Europäischen Kommission anerkannten Sprachfassungen dieser Lizenz sind gleichwertig. Die Parteien können sich auf die Sprachfassung ihrer Wahl berufen.
+
+14.Gerichtsstand
+Unbeschadet besonderer Vereinbarungen zwischen den Parteien gilt Folgendes: 
+—  Für alle Streitigkeiten über die Auslegung dieser Lizenz zwischen den Organen, Einrichtungen und sonstigen Stellen der Europäischen Union als Lizenzgeber und einem Lizenznehmer ist der Gerichtshof der Europäischen Union gemäß Artikel 272 des Vertrags über die Arbeitsweise der Europäischen Union zuständig; 
+—  Gerichtsstand für Streitigkeiten zwischen anderen Parteien über die Auslegung dieser Lizenz ist allein der Ort, an dem der Lizenzgeber seinen Wohnsitz oder den wirtschaftlichen Mittelpunkt seiner Tätigkeit hat. 
+
+15.Anwendbares Recht
+Unbeschadet besonderer Vereinbarungen zwischen den Parteien gilt Folgendes: 
+—  Diese Lizenz unterliegt dem Recht des Mitgliedstaats der Europäischen Union, in dem der Lizenzgeber seinen Sitz, Wohnsitz oder eingetragenen Sitz hat; 
+—  diese Lizenz unterliegt dem belgischen Recht, wenn der Lizenzgeber keinen Sitz, Wohnsitz oder eingetragenen Sitz in einem Mitgliedstaat der Europäischen Union hat.
+   
+Anlage

+                      EUROPEAN UNION PUBLIC LICENCE v. 1.2
+                      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

+# Lucia App
+
+In Germany, the government is rolling out an app for QR code based contact
+tracing. The app claims to protect user data but actually it does not, at least
+at the time of writing.
+
+The name of that app shall not be named here. It will be referred to in this 
+document as the "real" app.
+
+The Lucia app is capable of generating fake QR codes that users can use to
+check in at locations while not providing any personal data whatsoever.
+
+# How it works
+
+The "real" app has four different ways of checking in at a location:
+
+1. Letting a staff member at the location scan a QR code from your smartphone
+2. Scanning a QR code provided by the location using your smartphone
+3. Letting a staff member at the location scan a QR code from a special key tag
+
+The Lucia app can help you check in using the first option. It generates and
+shows a QR code that can be scanned by a staff member at the location. This QR
+code will be considered valid by the check-in system. It does not, however,
+contain any personal data about you.
+
+The "real" app puts an encrypted identifier into the QR code that tells the
+system who you are. This identifier is encrypted and cannot be decrypted by the
+check-in system. The check-in system will simply forward the encrypted
+identifier to a server where it will be stored. Some time later (days, maybe
+weeks) and only when an infected person has visited the location at the same
+time as you, the encrypted identifier will be decrypted.
+
+The Lucia app makes use of the fact that encrypted data is indistinguishable
+from random data. So instead of an encrypted identifier it puts random data
+into the QR code. This does not interfere with the check-in process because
+the check-in system does not decrypt the identifier. So basically, the Lucia
+app allows you to enter any location that you would need the "real" app for.
+
+It does not, however, let you perform a check-out procedure. That is not a
+problem because you will automatically get checked out after 24 hours. Also
+you will not be warned or contacted in the case of a possible infection.
+
+# Why though?
+
+I've created the app mainly out of curiosity. I wanted to see if it was possible
+to create fake QR codes that let you complete the check-in procedure at
+locations. It turned out to be possible and so I created this app to make it
+accessible to every person using an Android smartphone (Version 4.4 "Kitkat" or
+newer).
+
+# Future plans
+
+Currently I do not plan to develop this app any further. It does what it was
+made for. I expect the "real" app to advance and it is likely that the Lucia
+app will stop working some time in the future if the QR code format of the
+"real" app changes. I may or may not adjust the Lucia app to be compatible
+with any new or other features of the "real" app.
+
+You can, however, fork this repository and tinker with the code. Try, learn and
+improve things. Feel free to create pull requests or maintain your own fork.
