+ GNU GENERAL PUBLIC LICENSE
+
+ Version 2, June 1991
+ Copyright © 1989, 1991 Free Software Foundation, Inc.
+ 675 Mass Ave, Cambridge, MA 02139, USA
+
+Everyone is permitted to copy and distribute verbatim copies of this
+license document, but changing it is not allowed.
+
+ Preamble
+
+The licenses for most software are designed to take away your freedom to
+share and change it. By contrast, the GNU General Public License is
+intended to guarantee your freedom to share and change free software--to
+make sure the software is free for all its users. This General Public
+License applies to most of the Free Software Foundation's software and to
+any other program whose authors commit to using it. (Some other Free
+Software Foundation software is covered by the GNU Library General Public
+License instead.) You can apply it to your programs, too.
+
+When we speak of free software, we are referring to freedom, not price. Our
+General Public Licenses are designed to make sure that you have the freedom
+to distribute copies of free software (and charge for this service if you
+wish), that you receive source code or can get it if you want it, that you
+can change the software or use pieces of it in new free programs; and that
+you know you can do these things.
+
+To protect your rights, we need to make restrictions that forbid anyone to
+deny you these rights or to ask you to surrender the rights. These
+restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+For example, if you distribute copies of such a program, whether gratis or
+for a fee, you must give the recipients all the rights that you have. You
+must make sure that they, too, receive or can get the source code. And you
+must show them these terms so they know their rights.
+
+We protect your rights with two steps: (1) copyright the software, and (2)
+offer you this license which gives you legal permission to copy, distribute
+and/or modify the software.
+
+Also, for each author's protection and ours, we want to make certain that
+everyone understands that there is no warranty for this free software. If
+the software is modified by someone else and passed on, we want its
+recipients to know that what they have is not the original, so that any
+problems introduced by others will not reflect on the original authors'
+reputations.
+
+Finally, any free program is threatened constantly by software patents. We
+wish to avoid the danger that redistributors of a free program will
+individually obtain patent licenses, in effect making the program
+proprietary. To prevent this, we have made it clear that any patent must be
+licensed for everyone's free use or not licensed at all.
+
+The precise terms and conditions for copying, distribution and modification
+follow.
+
+ GNU GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+0. This License applies to any program or other work which contains a
+notice placed by the copyright holder saying it may be distributed under
+the terms of this General Public License. The "Program", below, refers to
+any such program or work, and a "work based on the Program" means either
+the Program or any derivative work under copyright law: that is to say, a
+work containing the Program or a portion of it, either verbatim or with
+modifications and/or translated into another language. (Hereinafter,
+translation is included without limitation in the term "modification".)
+Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of running the
+Program is not restricted, and the output from the Program is covered only
+if its contents constitute a work based on the Program (independent of
+having been made by running the Program). Whether that is true depends on
+what the Program does.
+
+1. You may copy and distribute verbatim copies of the Program's source code
+as you receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice and
+disclaimer of warranty; keep intact all the notices that refer to this
+License and to the absence of any warranty; and give any other recipients
+of the Program a copy of this License along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and you
+may at your option offer warranty protection in exchange for a fee.
+
+2. You may modify your copy or copies of the Program or any portion of it,
+thus forming a work based on the Program, and copy and distribute such
+modifications or work under the terms of Section 1 above, provided that you
+also meet all of these conditions:
+
+ a) You must cause the modified files to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ b) You must cause any work that you distribute or publish, that in
+ whole or in part contains or is derived from the Program or any part
+ thereof, to be licensed as a whole at no charge to all third parties
+ under the terms of this License.
+
+ c) If the modified program normally reads commands interactively when
+ run, you must cause it, when started running for such interactive use
+ in the most ordinary way, to print or display an announcement
+ including an appropriate copyright notice and a notice that there is
+ no warranty (or else, saying that you provide a warranty) and that
+ users may redistribute the program under these conditions, and telling
+ the user how to view a copy of this License. (Exception: if the
+ Program itself is interactive but does not normally print such an
+ announcement, your work based on the Program is not required to print
+ an announcement.)
+
+These requirements apply to the modified work as a whole. If identifiable
+sections of that work are not derived from the Program, and can be
+reasonably considered independent and separate works in themselves, then
+this License, and its terms, do not apply to those sections when you
+distribute them as separate works. But when you distribute the same
+sections as part of a whole which is a work based on the Program, the
+distribution of the whole must be on the terms of this License, whose
+permissions for other licensees extend to the entire whole, and thus to
+each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest your
+rights to work written entirely by you; rather, the intent is to exercise
+the right to control the distribution of derivative or collective works
+based on the Program.
+
+In addition, mere aggregation of another work not based on the Program with
+the Program (or with a work based on the Program) on a volume of a storage
+or distribution medium does not bring the other work under the scope of
+this License.
+
+3. You may copy and distribute the Program (or a work based on it, under
+Section 2) in object code or executable form under the terms of Sections 1
+and 2 above provided that you also do one of the following:
+
+ a) Accompany it with the complete corresponding machine-readable
+ source code, which must be distributed under the terms of Sections 1
+ and 2 above on a medium customarily used for software interchange; or,
+
+ b) Accompany it with a written offer, valid for at least three years,
+ to give any third party, for a charge no more than your cost of
+ physically performing source distribution, a complete machine-readable
+ copy of the corresponding source code, to be distributed under the
+ terms of Sections 1 and 2 above on a medium customarily used for
+ software interchange; or,
+
+ c) Accompany it with the information you received as to the offer to
+ distribute corresponding source code. (This alternative is allowed
+ only for noncommercial distribution and only if you received the
+ program in object code or executable form with such an offer, in
+ accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for making
+modifications to it. For an executable work, complete source code means all
+the source code for all modules it contains, plus any associated interface
+definition files, plus the scripts used to control compilation and
+installation of the executable. However, as a special exception, the source
+code distributed need not include anything that is normally distributed (in
+either source or binary form) with the major components (compiler, kernel,
+and so on) of the operating system on which the executable runs, unless
+that component itself accompanies the executable.
+
+If distribution of executable or object code is made by offering access to
+copy from a designated place, then offering equivalent access to copy the
+source code from the same place counts as distribution of the source code,
+even though third parties are not compelled to copy the source along with
+the object code.
+
+4. You may not copy, modify, sublicense, or distribute the Program except
+as expressly provided under this License. Any attempt otherwise to copy,
+modify, sublicense or distribute the Program is void, and will
+automatically terminate your rights under this License. However, parties
+who have received copies, or rights, from you under this License will not
+have their licenses terminated so long as such parties remain in full
+compliance.
+
+5. You are not required to accept this License, since you have not signed
+it. However, nothing else grants you permission to modify or distribute the
+Program or its derivative works. These actions are prohibited by law if you
+do not accept this License. Therefore, by modifying or distributing the
+Program (or any work based on the Program), you indicate your acceptance of
+this License to do so, and all its terms and conditions for copying,
+distributing or modifying the Program or works based on it.
+
+6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the original
+licensor to copy, distribute or modify the Program subject to these terms
+and conditions. You may not impose any further restrictions on the
+recipients' exercise of the rights granted herein. You are not responsible
+for enforcing compliance by third parties to this License.
+
+7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot distribute so
+as to satisfy simultaneously your obligations under this License and any
+other pertinent obligations, then as a consequence you may not distribute
+the Program at all. For example, if a patent license would not permit
+royalty-free redistribution of the Program by all those who receive copies
+directly or indirectly through you, then the only way you could satisfy
+both it and this License would be to refrain entirely from distribution of
+the Program.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply
+and the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any patents
+or other property right claims or to contest validity of any such claims;
+this section has the sole purpose of protecting the integrity of the free
+software distribution system, which is implemented by public license
+practices. Many people have made generous contributions to the wide range
+of software distributed through that system in reliance on consistent
+application of that system; it is up to the author/donor to decide if he or
+she is willing to distribute software through any other system and a
+licensee cannot impose that choice.
+
+This section is intended to make thoroughly clear what is believed to be a
+consequence of the rest of this License.
+
+8. If the distribution and/or use of the Program is restricted in certain
+countries either by patents or by copyrighted interfaces, the original
+copyright holder who places the Program under this License may add an
+explicit geographical distribution limitation excluding those countries, so
+that distribution is permitted only in or among countries not thus
+excluded. In such case, this License incorporates the limitation as if
+written in the body of this License.
+
+9. The Free Software Foundation may publish revised and/or new versions of
+the General Public License from time to time. Such new versions will be
+similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation. If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free
+Software Foundation.
+
+10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission. For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this. Our decision will be guided by the two goals of
+preserving the free status of all derivatives of our free software and of
+promoting the sharing and reuse of software generally.
+
+ NO WARRANTY
+
+11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO
+THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM
+PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR
+CORRECTION.
+
+12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.

+
+Vorwort
+
+ Die meisten Softwarelizenzen sind daraufhin entworfen worden, Ihnen
+ die Freiheit zu nehmen, die Software weiterzugeben und zu verändern.
+ Im Gegensatz dazu soll Ihnen die GNU General Public License, die
+ allgemeine öffentliche GNU-Lizenz, ebendiese Freiheit garantieren. Sie
+ soll sicherstellen, daß die Software für alle Benutzer frei ist. Diese
+ Lizenz gilt für den Großteil der von der Free Software Foundation
+ herausgegebenen Software und für alle anderen Programme, deren Autoren
+ ihr Werk dieser Lizenz unterstellt haben. Auch Sie können diese
+ Möglichkeit der Lizenzierung für Ihre Programme anwenden. (Ein anderer
+ Teil der Software der Free Software Foundation unterliegt stattdessen
+ der GNU Library General Public License, der allgemeinen öffentlichen
+ GNU-Lizenz für Bibliotheken.
+ )
+
+ Die Bezeichnung "freie" Software bezieht sich auf Freiheit, nicht auf
+ den Preis. Unsere Lizenzen sollen Ihnen die Freiheit garantieren,
+ Kopien freier Software zu verbreiten (und etwas für diesen Service zu
+ berechnen, wenn Sie möchten), die Möglichkeit, die Software im
+ Quelltext zu erhalten oder den Quelltext auf Wunsch zu bekommen. Die
+ Lizenzen sollen garantieren, daß Sie die Software ändern oder Teile
+ davon in neuen freien Programmen verwenden dürfen - und daß Sie
+ wissen, daß Sie dies alles tun dürfen.
+
+ Um Ihre Rechte zu schützen, müssen wir Einschränkungen machen, die es
+ jedem verbieten, Ihnen diese Rechte zu verweigern oder Sie
+ aufzufordern, auf diese Rechte zu verzichten. Aus diesen
+ Einschränkungen folgen bestimmte Verantwortlichkeiten für Sie, wenn
+ Sie Kopien der Software verbreiten oder sie verändern.
+
+ Beispielsweise müssen Sie den Empfängern alle Rechte gewähren, die Sie
+ selbst haben, wenn Sie - kostenlos oder gegen Bezahlung - Kopien eines
+ solchen Programms verbreiten. Sie müssen sicherstellen, daß auch sie
+ den Quelltext erhalten bzw. erhalten können. Und Sie müssen ihnen
+ diese Bedingungen zeigen, damit sie ihre Rechte kennen.
+
+ Wir schützen Ihre Rechte in zwei Schritten: (1) Wir stellen die
+ Software unter ein Urheberrecht (Copyright), und (2) wir bieten Ihnen
+ diese Lizenz an, die Ihnen das Recht gibt, die Software zu
+ vervielfältigen, zu verbreiten und/oder zu verändern.
+
+ Um die Autoren und uns zu schützen, wollen wir darüberhinaus
+ sicherstellen, daß jeder erfährt, daß für diese freie Software
+ keinerlei Garantie besteht. Wenn die Software von jemand anderem
+ modifiziert und weitergegeben wird, möchten wir, daß die Empfänger
+ wissen, daß sie nicht das Original erhalten haben, damit von anderen
+ verursachte Probleme nicht den Ruf des ursprünglichen Autors
+ schädigen.
+
+ Schließlich und endlich ist jedes freie Programm permanent durch
+ Software-Patente bedroht. Wir möchten die Gefahr ausschließen, daß
+ Distributoren eines freien Programms individuell Patente lizensieren -
+ mit dem Ergebnis, daß das Programm proprietär würde. Um dies zu
+ verhindern, haben wir klargestellt, daß jedes Patent entweder für
+ freie Benutzung durch jedermann lizenziert werden muß oder überhaupt
+ nicht lizenziert werden darf.
+
+ Es folgen die genauen Bedingungen für die Vervielfältigung,
+ Verbreitung und Bearbeitung:
+
+Bedingungen für die Vervielfältigung, Verbreitung und Bearbeitung
+
+ Paragraph 0. Diese Lizenz gilt für jedes Programm und jedes andere
+ Werk, in dem ein entsprechender Vermerk des Copyright-Inhabers darauf
+ hinweist, daß das Werk unter den Bestimmungen dieser General Public
+ License verbreitet werden darf. Im folgenden wird jedes derartige
+ Programm oder Werk als "das Programm" bezeichnet; die Formulierung
+ "auf dem Programm basierendes Werk" bezeichnet das Programm sowie
+ jegliche Bearbeitung des Programms im urheberrechtlichen Sinne, also
+ ein Werk, welches das Programm, auch auszugsweise, sei es unverändert
+ oder verändert und/oder in eine andere Sprache übersetzt, enthält. (Im
+ folgenden wird die Übersetzung ohne Einschränkung als "Bearbeitung"
+ eingestuft.) Jeder Lizenznehmer wird im folgenden als "Sie"
+ angesprochen.
+
+ Andere Handlungen als Vervielfältigung, Verbreitung und Bearbeitung
+ werden von dieser Lizenz nicht berührt; sie fallen nicht in ihren
+ Anwendungsbereich. Der Vorgang der Ausführung des Programms wird nicht
+ eingeschränkt, und die Ausgaben des Programms unterliegen dieser
+ Lizenz nur, wenn der Inhalt ein auf dem Programm basierendes Werk
+ darstellt (unabhängig davon, daß die Ausgabe durch die Ausführung des
+ Programmes erfolgte). Ob dies zutrifft, hängt von den Funktionen des
+ Programms ab.
+
+ Paragraph 1. Sie dürfen auf beliebigen Medien unveränderte Kopien des
+ Quelltextes des Programms, wie sie ihn erhalten haben, anfertigen und
+ verbreiten. Voraussetzung hierfür ist, daß Sie mit jeder Kopie einen
+ entsprechenden Copyright-Vermerk sowie einen Haftungsausschluß
+ veröffentlichen, alle Vermerke, die sich auf diese Lizenz und das
+ Fehlen einer Garantie beziehen, unverändert lassen und desweiteren
+ allen anderen Empfängern des Programms zusammen mit dem Programm eine
+ Kopie dieser Lizenz zukommen lassen.
+
+ Sie dürfen für den eigentlichen Kopiervorgang eine Gebühr verlangen.
+ Wenn Sie es wünschen, dürfen Sie auch gegen Entgelt eine Garantie für
+ das Programm anbieten.
+
+ Paragraph 2. Sie dürfen Ihre Kopie(n) des Programms oder eines Teils
+ davon verändern, wodurch ein auf dem Programm basierendes Werk
+ entsteht; Sie dürfen derartige Bearbeitungen unter den Bestimmungen
+ von Paragraph 1 vervielfältigen und verbreiten, vorausgesetzt, daß
+ zusätzlich alle folgenden Bedingungen erfüllt werden:
+
+ (a)
+ Sie müssen die veränderten Dateien mit einem auffälligen
+ Vermerk versehen, der auf die von Ihnen vorgenommene
+ Modifizierung und das Datum jeder Änderung hinweist.
+
+ (b)
+ Sie müssen dafür sorgen, daß jede von Ihnen verbreitete oder
+ veröffentlichte Arbeit, die ganz oder teilweise von dem
+ Programm oder Teilen davon abgeleitet ist, Dritten gegenüber
+ als Ganzes unter den Bedingungen dieser Lizenz ohne
+ Lizenzgebühren zur Verfügung gestellt wird.
+
+ (c)
+ Wenn das veränderte Programm normalerweise bei der Ausführung
+ interaktiv Kommandos einliest, müssen Sie dafür sorgen, daß es,
+ wenn es auf dem üblichsten Wege für solche interaktive Nutzung
+ gestartet wird, eine Meldung ausgibt oder ausdruckt, die einen
+ geeigneten Copyright-Vermerk enthält sowie einen Hinweis, daß
+ es keine Gewährleistung gibt (oder anderenfalls, daß Sie
+ Garantie leisten), und daß die Benutzer das Programm unter
+ diesen Bedingungen weiter verbreiten dürfen. Auch muß der
+ Benutzer darauf hingewiesen werden, wie er eine Kopie dieser
+ Lizenz ansehen kann. (Ausnahme: Wenn das Programm selbst
+ interaktiv arbeitet, aber normalerweise keine derartige Meldung
+ ausgibt, muß Ihr auf dem Programm basierendes Werk auch keine
+ solche Meldung ausgeben).
+
+ Diese Anforderungen betreffen das veränderte Werk als Ganzes. Wenn
+ identifizierbare Abschnitte des Werkes nicht von dem Programm
+ abgeleitet sind und vernünftigerweise selbst als unabhängige und
+ eigenständige Werke betrachtet werden können, dann erstrecken sich
+ diese Lizenz und ihre Bedingungen nicht auf diese Abschnitte, wenn sie
+ als eigenständige Werke verbreitet werden. Wenn Sie jedoch dieselben
+ Abschnitte als Teil eines Ganzen verbreiten, das ein auf dem Programm
+ basierendes Werk darstellt, dann muß die Verbreitung des Ganzen nach
+ den Bedingungen dieser Lizenz erfolgen, deren Bedingungen für weitere
+ Lizenznehmer somit auf die Gesamtheit ausgedehnt werden - und damit
+ auf jeden einzelnen Teil, unabhängig vom jeweiligen Autor.
+
+ Somit ist es nicht die Absicht dieses Abschnittes, Rechte für Werke in
+ Anspruch zu nehmen oder zu beschneiden, die komplett von Ihnen
+ geschrieben wurden; vielmehr ist es die Absicht, die Rechte zur
+ Kontrolle der Verbreitung von Werken, die auf dem Programm basieren
+ oder unter seiner auszugsweisen Verwendung zusammengestellt worden
+ sind, auszuüben.
+
+ Ferner bringt ein einfaches Zusammenstellen eines anderen Werkes, das
+ nicht auf dem Programm basiert, zusammen mit dem Programm oder einem
+ auf dem Programm basierenden Werk auf ein- und demselben Speicher-
+ oder Vertriebsmedium das andere Werk nicht in den Anwendungsbereich
+ dieser Lizenz.
+
+ Paragraph 3. Sie dürfen das Programm (oder ein darauf basierendes Werk
+ gemäß Paragraph 2) als Objectcode oder in ausführbarer Form unter den
+ Bedingungen von Paragraph 1 und 2 vervielfältigen und verbreiten -
+ vorausgesetzt, daß Sie außerdem eine der folgenden Leistungen
+ erbringen:
+
+ (a)
+ Liefern Sie das Programm zusammen mit dem vollständigen
+ zugehörigen maschinenlesbaren Quelltext auf einem für den
+ Datenaustausch üblichen Medium aus, wobei die Verteilung unter
+ den Bedingungen der Paragraphen 1 und 2 erfolgen muß. Oder:
+
+ (b)
+ Liefern Sie das Programm zusammen mit einem mindestens drei
+ Jahre lang gültigen schriftlichen Angebot aus, jedem Dritten
+ eine vollständige maschinenlesbare Kopie des Quelltextes zur
+ Verfügung zu stellen - zu nicht höheren Kosten als denen, die
+ durch den physikalischen Kopiervorgang anfallen -, wobei der
+ Quelltext unter den Bedingungen der Paragraphen 1 und 2 auf
+ einem für den Datenaustausch üblichen Medium weitergegeben
+ wird. Oder:
+
+ (c)
+ Liefern Sie das Programm zusammen mit dem schriftlichen Angebot
+ der Zurverfügungstellung des Quelltextes aus, das Sie selbst
+ erhalten haben. (Diese Alternative ist nur für
+ nicht-kommerzielle Verbreitung zulässig und nur, wenn Sie das
+ Programm als Objectcode oder in ausführbarer Form mit einem
+ entsprechenden Angebot gemäß Absatz b erhalten haben.)
+
+ Unter dem Quelltext eines Werkes wird diejenige Form des Werkes
+ verstanden, die für Bearbeitungen vorzugsweise verwendet wird. Für ein
+ ausführbares Programm bedeutet "der komplette Quelltext": Der
+ Quelltext aller im Programm enthaltenen Module einschließlich aller
+ zugehörigen Modulschnittstellen-Definitionsdateien sowie der zur
+ Compilation und Installation verwendeten Skripte. Als besondere
+ Ausnahme jedoch braucht der verteilte Quelltext nichts von dem zu
+ enthalten, was üblicherweise (entweder als Quelltext oder in binärer
+ Form) zusammen mit den Hauptkomponenten des Betriebssystems (Kernel,
+ Compiler usw.) geliefert wird, unter dem das Programm läuft - es sei
+ denn, diese Komponente selbst gehört zum ausführbaren Programm.
+
+ Wenn die Verbreitung eines ausführbaren Programms oder des Objectcodes
+ dadurch erfolgt, daß der Kopierzugriff auf eine dafür vorgesehene
+ Stelle gewährt wird, so gilt die Gewährung eines gleichwertigen
+ Zugriffs auf den Quelltext als Verbreitung des Quelltextes, auch wenn
+ Dritte nicht dazu gezwungen sind, den Quelltext zusammen mit dem
+ Objectcode zu kopieren.
+
+ Paragraph 4. Sie dürfen das Programm nicht vervielfältigen, verändern,
+ weiter lizenzieren oder verbreiten, sofern es nicht durch diese Lizenz
+ ausdrücklich gestattet ist. Jeder anderweitige Versuch der
+ Vervielfältigung, Modifizierung, Weiterlizenzierung und Verbreitung
+ ist nichtig und beendet automatisch Ihre Rechte unter dieser Lizenz.
+ Jedoch werden die Lizenzen Dritter, die von Ihnen Kopien oder Rechte
+ unter dieser Lizenz erhalten haben, nicht beendet, solange diese die
+ Lizenz voll anerkennen und befolgen.
+
+ Paragraph 5. Sie sind nicht verpflichtet, diese Lizenz anzunehmen, da
+ Sie sie nicht unterzeichnet haben. Jedoch gibt Ihnen nichts anderes
+ die Erlaubnis, das Programm oder von ihm abgeleitete Werke zu
+ verändern oder zu verbreiten. Diese Handlungen sind gesetzlich
+ verboten, wenn Sie diese Lizenz nicht anerkennen. Indem Sie das
+ Programm (oder ein darauf basierendes Werk) verändern oder verbreiten,
+ erklären Sie Ihr Einverständnis mit dieser Lizenz und mit allen ihren
+ Bedingungen bezüglich der Vervielfältigung, Verbreitung und
+ Veränderung des Programms oder eines darauf basierenden Werkes.
+
+ Paragraph 6. Jedesmal, wenn Sie das Programm (oder ein auf dem
+ Programm basierendes Werk) weitergeben, erhält der Empfänger
+ automatisch vom ursprünglichen Lizenzgeber die Lizenz, das Programm
+ entsprechend den hier festgelegten Bestimmungen zu vervielfältigen, zu
+ verbreiten und zu verändern. Sie dürfen keine weiteren Einschränkungen
+ der Durchsetzung der hierin zugestandenen Rechte des Empfängers
+ vornehmen. Sie sind nicht dafür verantwortlich, die Einhaltung dieser
+ Lizenz durch Dritte durchzusetzen.
+
+ Paragraph 7. Sollten Ihnen infolge eines Gerichtsurteils, des Vorwurfs
+ einer Patentverletzung oder aus einem anderen Grunde (nicht auf
+ Patentfragen begrenzt) Bedingungen (durch Gerichtsbeschluß, Vergleich
+ oder anderweitig) auferlegt werden, die den Bedingungen dieser Lizenz
+ widersprechen, so befreien Sie diese Umstände nicht von den
+ Bestimmungen dieser Lizenz. Wenn es Ihnen nicht möglich ist, das
+ Programm unter gleichzeitiger Beachtung der Bedingungen in dieser
+ Lizenz und Ihrer anderweitigen Verpflichtungen zu verbreiten, dann
+ dürfen Sie als Folge das Programm überhaupt nicht verbreiten. Wenn zum
+ Beispiel ein Patent nicht die gebührenfreie Weiterverbreitung des
+ Programms durch diejenigen erlaubt, die das Programm direkt oder
+ indirekt von Ihnen erhalten haben, dann besteht der einzige Weg,
+ sowohl das Patentrecht als auch diese Lizenz zu befolgen, darin, ganz
+ auf die Verbreitung des Programms zu verzichten.
+
+ Sollte sich ein Teil dieses Paragraphen als ungültig oder unter
+ bestimmten Umständen nicht durchsetzbar erweisen, so soll dieser
+ Paragraph seinem Sinne nach angewandt werden; im übrigen soll dieser
+ Paragraph als Ganzes gelten.
+
+ Zweck dieses Paragraphen ist nicht, Sie dazu zu bringen, irgendwelche
+ Patente oder andere Eigentumsansprüche zu verletzen oder die
+ Gültigkeit solcher Ansprüche zu bestreiten; dieser Paragraph hat
+ einzig den Zweck, die Integrität des Verbreitungssystems der freien
+ Software zu schützen, das durch die Praxis öffentlicher Lizenzen
+ verwirklicht wird. Viele Leute haben großzügige Beiträge zu dem großen
+ Angebot der mit diesem System verbreiteten Software im Vertrauen auf
+ die konsistente Anwendung dieses Systems geleistet; es liegt am
+ Autor/Geber, zu entscheiden, ob er die Software mittels irgendeines
+ anderen Systems verbreiten will; ein Lizenznehmer hat auf diese
+ Entscheidung keinen Einfluß.
+
+ Dieser Paragraph ist dazu gedacht, deutlich klarzustellen, was als
+ Konsequenz aus dem Rest dieser Lizenz betrachtet wird.
+
+ Paragraph 8. Wenn die Verbreitung und/oder die Benutzung des Programms
+ in bestimmten Staaten entweder durch Patente oder durch
+ urheberrechtlich geschützte Schnittstellen eingeschränkt ist, kann der
+ Urheberrechtsinhaber, der das Programm unter diese Lizenz gestellt
+ hat, eine explizite geographische Begrenzung der Verbreitung angeben,
+ in der diese Staaten ausgeschlossen werden, so daß die Verbreitung nur
+ innerhalb und zwischen den Staaten erlaubt ist, die nicht
+ ausgeschlossen sind. In einem solchen Fall beinhaltet diese Lizenz die
+ Beschränkung, als wäre sie in diesem Text niedergeschrieben.
+
+ Paragraph 9. Die Free Software Foundation kann von Zeit zu Zeit
+ überarbeitete und/oder neue Versionen der General Public License
+ veröffentlichen. Solche neuen Versionen werden vom Grundprinzip her
+ der gegenwärtigen entsprechen, können aber im Detail abweichen, um
+ neuen Problemen und Anforderungen gerecht zu werden.
+
+ Jede Version dieser Lizenz hat eine eindeutige Versionsnummer. Wenn in
+ einem Programm angegeben wird, daß es dieser Lizenz in einer
+ bestimmten Versionsnummer oder "jeder späteren Version" ("any later
+ version") unterliegt, so haben Sie die Wahl, entweder den Bestimmungen
+ der genannten Version zu folgen oder denen jeder beliebigen späteren
+ Version, die von der Free Software Foundation veröffentlicht wurde.
+ Wenn das Programm keine Versionsnummer angibt, können Sie eine
+ beliebige Version wählen, die je von der Free Software Foundation
+ veröffentlicht wurde.
+
+ Paragraph 10. Wenn Sie den Wunsch haben, Teile des Programms in
+ anderen freien Programmen zu verwenden, deren Bedingungen für die
+ Verbreitung anders sind, schreiben Sie an den Autor, um ihn um die
+ Erlaubnis zu bitten. Für Software, die unter dem Copyright der Free
+ Software Foundation steht, schreiben Sie an die Free Software
+ Foundation; wir machen zu diesem Zweck gelegentlich Ausnahmen. Unsere
+ Entscheidung wird von den beiden Zielen geleitet werden, zum einen den
+ freien Status aller von unserer freien Software abgeleiteten Werke zu
+ erhalten und zum anderen das gemeinschaftliche Nutzen und
+ Wiederverwenden von Software im allgemeinen zu fördern.
+
+ Keine Gewährleistung
+
+ Paragraph 11. Da das Programm ohne jegliche Kosten lizenziert wird,
+ besteht keinerlei Gewährleistung für das Programm, soweit dies
+ gesetzlich zulässig ist. Sofern nicht anderweitig schriftlich
+ bestätigt, stellen die Copyright-Inhaber und/oder Dritte das Programm
+ so zur Verfügung, "wie es ist", ohne irgendeine Gewährleistung, weder
+ ausdrücklich noch implizit, einschließlich - aber nicht begrenzt auf -
+ Marktreife oder Verwendbarkeit für einen bestimmten Zweck. Das volle
+ Risiko bezüglich Qualität und Leistungsfähigkeit des Programms liegt
+ bei Ihnen. Sollte sich das Programm als fehlerhaft herausstellen,
+ liegen die Kosten für notwendigen Service, Reparatur oder Korrektur
+ bei Ihnen.
+
+ Paragraph 12. In keinem Fall, außer wenn durch geltendes Recht
+ gefordert oder schriftlich zugesichert, ist irgendein
+ Copyright-Inhaber oder irgendein Dritter, der das Programm wie oben
+ erlaubt modifiziert oder verbreitet hat, Ihnen gegenüber für
+ irgendwelche Schäden haftbar, einschließlich jeglicher allgemeiner
+ oder spezieller Schäden, Schäden durch Seiteneffekte (Nebenwirkungen)
+ oder Folgeschäden, die aus der Benutzung des Programms oder der
+ Unbenutzbarkeit des Programms folgen (einschließlich - aber nicht
+ beschränkt auf - Datenverluste, fehlerhafte Verarbeitung von Daten,
+ Verluste, die von Ihnen oder anderen getragen werden müssen, oder dem
+ Unvermögen des Programms, mit irgendeinem anderen Programm
+ zusammenzuarbeiten), selbst wenn ein Copyright-Inhaber oder Dritter
+ über die Möglichkeit solcher Schäden unterrichtet worden war.
+
+ Ende der Bedingungen

+
+Anhang: Wie Sie diese Bedingungen auf Ihre neuen Programme anwendbar machen
+
+ Wenn Sie ein neues Programm entwickeln und wollen, daß es von
+ größtmöglichem Nutzen für die Allgemeinheit ist, dann erreichen Sie
+ das am besten, indem Sie es zu freier Software machen, die jeder unter
+ diesen Bestimmungen weiterverbreiten und verändern kann.
+
+ Um dies zu erreichen, fügen Sie die folgenden Anmerkungen zu Ihrem
+ Programm hinzu. Am sichersten ist es, sie an den Anfang einer jeden
+ Quelldatei zu stellen, um den Gewährleistungsausschluß möglichst
+ deutlich darzustellen; außerdem sollte jede Datei mindestens eine
+ "Copyright"-Zeile besitzen sowie einen kurzen Hinweis darauf, wo die
+ vollständige Lizenz gefunden werden kann.

+Ligatex Version 0.2
+
+Das Programm Ligatex hebt in Texten, die für Verwendung mit dem Textsatzsystem
+TeX geschrieben sind, an Stellen wo sie nicht hingehören, Ligaturen auf.
+Es greift dazu auf einen wörterbuchbasierten Ansatz zurück und kann daher nur
+für Texte, die auf Deutsch verfaßt sind, sinnvoll verwandt werden. Eine
+Anpassung für andere Sprachen kann durch Ersatz der Datei ligatex.l erfolgen.
+Der Autor würde sich über solche Anpassungen freuen, sowie über Fehlermeldungen
+zur vorliegenden deutschen Version.
+
+The programme ligatex converts texts that are written for use with the layout
+system TeX in such a way that ligatures are removed from certain places. The
+programm currently only treats texts written in German. Thus this programme is
+probably only of interest to you if you have some knowledge of the German
+language. Therefore the rest of this documentation is only available in German.
+However, the author welcomes additions to ligatex in order to make it usable
+with any language. For this purpose the file ligatex.l should be edited.

+
+ If an element of ARGV starts with '-', and is not exactly "-" or "--",
+ then it is an option element. The characters of this element
+ (aside from the initial '-') are option characters. If `getopt'
+ is called repeatedly, it returns successively each of the option characters
+ from each of the option elements.
+
+ If `getopt' finds another option character, it returns that character,
+ updating `optind' and `nextchar' so that the next call to `getopt' can
+ resume the scan with the following option character or ARGV-element.
+
+ If there are no more option characters, `getopt' returns -1.
+ Then `optind' is the index in ARGV of the first ARGV-element
+ that is not an option. (The ARGV-elements have been permuted
+ so that those that are not options now come last.)
+
+ OPTSTRING is a string containing the legitimate option characters.
+ If an option character is seen that is not listed in OPTSTRING,
+ return '?' after printing an error message. If you set `opterr' to
+ zero, the error message is suppressed but we still return '?'.
+
+ If a char in OPTSTRING is followed by a colon, that means it wants an arg,
+ so the following text in the same ARGV-element, or the text of the following
+ ARGV-element, is returned in `optarg'. Two colons mean an option that
+ wants an optional arg; if there is text in the current ARGV-element,
+ it is returned in `optarg', otherwise `optarg' is set to zero.
+
+ If OPTSTRING starts with `-' or `+', it requests different methods of
+ handling the non-option ARGV-elements.
+ See the comments about RETURN_IN_ORDER and REQUIRE_ORDER, above.
+
+ Long-named options begin with `--' instead of `-'.
+ Their names may be abbreviated as long as the abbreviation is unique
+ or is an exact match for some defined option. If they have an
+ argument, it follows the option name in the same ARGV-element, separated
+ from the option name by a `=', or else the in next ARGV-element.
+ When `getopt' finds a long-named option, it returns 0 if that option's
+ `flag' field is nonzero, the value of the option's `val' field
+ if the `flag' field is zero.
+
+ The elements of ARGV aren't really const, because we permute them.
+ But we pretend they're const in the prototype to be compatible
+ with other systems.
+
+ LONGOPTS is a vector of `struct option' terminated by an
+ element containing a name which is zero.
+
+ LONGIND returns the index in LONGOPT of the long-named option found.
+ It is only valid when a long-named option has been found by the most
+ recent call.
+
+ If LONG_ONLY is nonzero, '-' as well as '--' can introduce

+.TH ligatex 1 "22. November 2000" "Version 0.2.0"
+.SH NAME
+ligatex
+\- ligatex
+.SH SYNOPSIS
+\fBligatex\fP [\fB--version --help\fP]
+.SH DESCRIPTION
+.PP
+Ligatex Version 0.2.0
+
+The programme ligatex converts texts that are written for use with the layout
+system TeX in such a way that ligatures are removed from certain places. The
+programm currently only treats texts written in German. Thus this programme is
+probably only of interest to you if you have some knowledge of the German
+language. Therefore the rest of this documentation is only available in German.
+However, the author welcomes additions to ligatex in order to make it usable
+with any language. For this purpose the file ligatex.l should be edited.
+
+Das Programm Ligatex hebt in Texten, die für Verwendung mit dem Textsatzsystem
+TeX geschrieben sind, an Stellen wo sie nicht hingehören, Ligaturen auf.
+Es greift dazu auf einen wörterbuchbasierten Ansatz zurück und kann daher nur
+für Texte, die auf Deutsch verfaßt sind, sinnvoll verwandt werden. Eine
+Anpassung für andere Sprachen kann durch Ersatz der Datei ligatex.l erfolgen.
+Der Autor würde sich über solche Anpassungen freuen, sowie über Fehlermeldungen
+zur vorliegenden deutschen Version.
+
+.SH Handhabung
+
+Das Programm liest Text von der Standardeingabe und schreibt konvertierten Text
+an die Standardausgabe:
+
+Durch den Aufruf
+
+ligatex < rein.tex > raus.tex
+
+erhält man die veränderte Version raus.tex. Die Originalversion
+rein.tex wird nicht verändert. raus.tex kann ohne Fehler zu
+verursachen wieder prozessiert werden.
+
+ligatex < raus.tex > raus2.tex
+
+raus.tex und raus2.tex sollten identisch sein, falls raus.tex nicht
+verändert wurde.
+
+.SH LaTeX
+
+Die Verwendung von german.sty oder babel.sty wird vorausgesetzt.
+LaTeX 2.09 wird nicht unterstützt.
+Die Datei wird erst ab \\begin{document} auf Ligaturen untersucht.
+Dateien, denen diese Zeile fehlt, können mittels
+
+%\\begin{ligatex}
+
+Text mit Ligaturen.
+
+%\\end{ligatex}
+
+dennoch überprüft werden. Die Anzahl der Prozentzeichen ist beliebig.
+Nach einem %\\end{ligatex} wird bis zum nächsten %\\begin{ligatex}
+kein Text auf Ligaturen untersucht. Dadurch können auch verbatim-Umgebungen
+mit LaTeX-Quelltext im Dokument enthalten sein:
+
+%\\end{ligatex}
+
+\\begin{verbatim}
+
+LaTeX-Text
+
+\\end{verbatim}
+
+%\\begin{ligatex}
+
+Vor den Schaltern für die Pseudo-Umgebung ligatex darf kein Text in der
+Zeile stehen. Sie müssen nicht paarig auftreten.
+
+.SH German.sty
+
+Neben german.sty wird auch ngerman.sty (die flasche Rechtschreibung)
+unterstützt.
+
+.SH Babel.sty
+
+Bei Verwendung von babel.sty bestimmt die Reihenfolge, in der die
+Sprachdefinitionen geladen werden, die am Anfang des Dokumentes
+aktive Sprache. \fPLigaTeX\fP kann diese aber nur dann feststellen,
+wenn Sie die Syntax
+
+\\usepackage[sprach1,sprache2,german,sprache3]{babel}
+
+verwenden. Schreiben Sie
+
+\\documentclass[option1,option2,sprache1,german,weitere,optionen]{book}
+
+kann \fPLigaTeX\fP weiter Sprachen nicht zuverlässig von weiteren Optionen
+unterscheiden und bleibt daher am Dokumentanfang inaktiv,
+
+Neben der Option german werden auch die Optionen austrian,
+ngerman und naustrian unterstützt.
+
+Das Makro \\foreignlanguage wird unterstützt.
+
+.SH Eigene Definitionen
+
+Sie können Makros definieren, deren Name verändert würde, z.B.
+\\auflage, dies gilt auch für Umgebungen aber nicht für Pakete.
+
+.SH Text-Kodierung
+
+Der Text kann in \fPLatin-1\fP, \fPTeX\fP oder
+\fPHTML\fP kodiert sein. Das Programm stellt dies selbsttätig fest und gibt
+entsprechend kodierten Text wieder aus.
+HTML-Dateien werden immer prozessiert.
+
+.SH Caveat
+
+Verbatim-Umgebungen, die LaTeX-Text enthalten,
+dürften für Verwirrung sorgen. Abhilfe schafft die
+Pseudo-Umgebung ligatex.
+
+
