10      The GNU General Public License is a free, copyleft license for
11                              Preamble  software and other kinds of works.
12    
13    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.    The licenses for most software and other practical works are designed
14    to take away your freedom to share and change the works.  By contrast,
15    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.  the GNU General Public License is intended to guarantee your freedom to

These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it.  software for all its users.  We, the Free Software Foundation, use the

21    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.

31    certain responsibilities if you distribute copies of the software, or if
32    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".  you modify it: responsibilities to respect the freedom of others.
33    
34  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.    For example, if you distribute copies of such a program, whether
35    gratis or for a fee, you must pass on to the recipients the same
36  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.  freedoms that you received.  You must make sure that they, too, receive

39    
40    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:    Developers that use the GNU GPL protect your rights with two steps:
41    (1) assert copyright on the software, and (2) offer you this License
42    a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change.  giving you legal permission to copy, distribute and/or modify it.
43    
44    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.    For the developers' and authors' protection, the GPL clearly explains
45    that there is no warranty for this free software.  For both users' and
46    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.)  authors' sake, the GPL requires that modified versions be marked as
47    changed, so that their problems will not be attributed erroneously to
48  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.  authors of previous versions.
49    
50  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.    Some devices are designed to deny users access to install or run
51    modified versions of the software inside them, although the manufacturer

60    
61  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.    Finally, every program is threatened constantly by software patents.
62    States should not allow patents to restrict development and use of

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.  make it effectively proprietary.  To prevent this, the GPL assures that
66    patents cannot be used to render the program non-free.
67    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.

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.  modification follow.
70    
71    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.                         TERMS AND CONDITIONS
72    
73  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.    0. Definitions.
74    
75  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 License" refers to version 3 of the GNU General Public License.
76    
77  This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License.    "Copyright" also means copyright-like laws that apply to other kinds of
78    works, such as semiconductor masks.
79    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  
80  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.    "The Program" refers to any copyrightable work licensed under this
81    License.  Each licensee is addressed as "you".  "Licensees" and
82    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.  "recipients" may be individuals or organizations.
83    
84  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.    To "modify" a work means to copy from or adapt all or part of the work
85    in a fashion requiring copyright permission, other than the making of an

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.  exact copy.  The resulting work is called a "modified version" of the
87    earlier work or a work "based on" the earlier work.

90    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.  on the Program.
91    
92    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.    To "propagate" a work means to do anything with it that, without
93    permission, would make you directly or secondarily liable for

98    If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms.

110    menu, a prominent item in the list meets this criterion.
111    
112      1. Source Code.
113    
114      The "source code" for a work means the preferred form of the work
115    for making modifications to it.  "Object code" means any non-source
116    form of a work.
117    
118      A "Standard Interface" means an interface that either is an official
119    standard defined by a recognized standards body, or, in the case of
120    interfaces specified for a particular programming language, one that
121    is widely used among developers working in that language.
122    
123      The "System Libraries" of an executable work include anything, other
124    than the work as a whole, that (a) is included in the normal form of
125    packaging a Major Component, but which is not part of that Major
126    Component, and (b) serves only to enable use of the work with that
127    Major Component, or to implement a Standard Interface for which an
128    implementation is available to the public in source code form.  A
129    "Major Component", in this context, means a major essential component
130    (kernel, window system, and so on) of the specific operating system
131    (if any) on which the executable work runs, or a compiler used to
132    produce the work, or an object code interpreter used to run it.
133    
134      The "Corresponding Source" for a work in object code form means all
135    the source code needed to generate, install, and (for an executable
136    work) run the object code and to modify the work, including scripts to
137    control those activities.  However, it does not include the work's
138    System Libraries, or general-purpose tools or generally available free
139    programs which are used unmodified in performing those activities but
140    which are not part of the work.  For example, Corresponding Source
141    includes interface definition files associated with source files for
142    the work, and the source code for shared libraries and dynamically
143    linked subprograms that the work is specifically designed to require,
144    such as by intimate data communication or control flow between those
145    subprograms and other parts of the work.
146    
147      The Corresponding Source need not include anything that users
148    can regenerate automatically from other parts of the Corresponding
149    Source.
150    
151      The Corresponding Source for a work in source code form is that
152    same work.
153    
154      2. Basic Permissions.
155    
156      All rights granted under this License are granted for the term of
157    copyright on the Program, and are irrevocable provided the stated
158    conditions are met.  This License explicitly affirms your unlimited
159    permission to run the unmodified Program.  The output from running a
160    covered work is covered by this License only if the output, given its
161    content, constitutes a covered work.  This License acknowledges your
162    rights of fair use or other equivalent, as provided by copyright law.
163    
164      You may make, run and propagate covered works that you do not
165    convey, without conditions so long as your license otherwise remains
166    in force.  You may convey covered works to others for the sole purpose
167    of having them make modifications exclusively for you, or provide you
168    with facilities for running those works, provided that you comply with
169    the terms of this License in conveying all material for which you do
170    not control copyright.  Those thus making or running the covered works
171    for you must do so exclusively on your behalf, under your direction
172    and control, on terms that prohibit them from making any copies of
173    your copyrighted material outside their relationship with you.
174    
175      Conveying under any other circumstances is permitted solely under
176    the conditions stated below.  Sublicensing is not allowed; section 10
177    makes it unnecessary.
178    
179      3. Protecting Users' Legal Rights From Anti-Circumvention Law.
180    
181      No covered work shall be deemed part of an effective technological
182    measure under any applicable law fulfilling obligations under article
183    11 of the WIPO copyright treaty adopted on 20 December 1996, or
184    similar laws prohibiting or restricting circumvention of such
185    measures.
186    
187      When you convey a covered work, you waive any legal power to forbid
188    circumvention of technological measures to the extent such circumvention
189    is effected by exercising rights under this License with respect to
190    the covered work, and you disclaim any intention to limit operation or
191    modification of the work as a means of enforcing, against the work's
192    users, your or third parties' legal rights to forbid circumvention of
193    technological measures.
194    
195      4. Conveying Verbatim Copies.
196    
197      You may convey verbatim copies of the Program's source code as you
198    receive it, in any medium, provided that you conspicuously and
199    appropriately publish on each copy an appropriate copyright notice;
200    keep intact all notices stating that this License and any
201    non-permissive terms added in accord with section 7 apply to the code;
202    keep intact all notices of the absence of any warranty; and give all
203    recipients a copy of this License along with the Program.
204    
205      You may charge any price or no price for each copy that you convey,
206    and you may offer support or warranty protection for a fee.
207    
208      5. Conveying Modified Source Versions.
209    
210      You may convey a work based on the Program, or the modifications to
211    produce it from the Program, in the form of source code under the
212    terms of section 4, provided that you also meet all of these conditions:
213    
214        a) The work must carry prominent notices stating that you modified
215        it, and giving a relevant date.
216    
217        b) The work must carry prominent notices stating that it is
218        released under this License and any conditions added under section
219        7.  This requirement modifies the requirement in section 4 to
220        "keep intact all notices".
221    
222        c) You must license the entire work, as a whole, under this
223        License to anyone who comes into possession of a copy.  This
224        License will therefore apply, along with any applicable section 7
225        additional terms, to the whole of the work, and all its parts,
226        regardless of how they are packaged.  This License gives no
227        permission to license the work in any other way, but it does not
228        invalidate such permission if you have separately received it.
229    
230        d) If the work has interactive user interfaces, each must display
231        Appropriate Legal Notices; however, if the Program has interactive
232        interfaces that do not display Appropriate Legal Notices, your
233        work need not make them do so.
234    
235      A compilation of a covered work with other separate and independent
236    works, which are not by their nature extensions of the covered work,
237    and which are not combined with it such as to form a larger program,
238    in or on a volume of a storage or distribution medium, is called an
239    "aggregate" if the compilation and its resulting copyright are not
240    used to limit the access or legal rights of the compilation's users
241    beyond what the individual works permit.  Inclusion of a covered work
242    in an aggregate does not cause this License to apply to the other
243    parts of the aggregate.
244    
245      6. Conveying Non-Source Forms.
246    
247      You may convey a covered work in object code form under the terms
248    of sections 4 and 5, provided that you also convey the
249    machine-readable Corresponding Source under the terms of this License,
250    in one of these ways:
251    
252        a) Convey the object code in, or embodied in, a physical product
253        (including a physical distribution medium), accompanied by the
254        Corresponding Source fixed on a durable physical medium
255        customarily used for software interchange.
256    
257        b) Convey the object code in, or embodied in, a physical product
258        (including a physical distribution medium), accompanied by a
259        written offer, valid for at least three years and valid for as
260        long as you offer spare parts or customer support for that product
261        model, to give anyone who possesses the object code either (1) a
262        copy of the Corresponding Source for all the software in the
263        product that is covered by this License, on a durable physical
264        medium customarily used for software interchange, for a price no
265        more than your reasonable cost of physically performing this
266        conveying of source, or (2) access to copy the
267        Corresponding Source from a network server at no charge.
268    
269        c) Convey individual copies of the object code with a copy of the
270        written offer to provide the Corresponding Source.  This
271        alternative is allowed only occasionally and noncommercially, and
272        only if you received the object code with such an offer, in accord
273        with subsection 6b.
274    
275        d) Convey the object code by offering access from a designated
276        place (gratis or for a charge), and offer equivalent access to the
277        Corresponding Source in the same way through the same place at no
278        further charge.  You need not require recipients to copy the
279        Corresponding Source along with the object code.  If the place to
280        copy the object code is a network server, the Corresponding Source
281        may be on a different server (operated by you or a third party)
282        that supports equivalent copying facilities, provided you maintain
283        clear directions next to the object code saying where to find the
284        Corresponding Source.  Regardless of what server hosts the
285        Corresponding Source, you remain obligated to ensure that it is
286        available for as long as needed to satisfy these requirements.
287    
288        e) Convey the object code using peer-to-peer transmission, provided
289        you inform other peers where the object code and Corresponding
290        Source of the work are being offered to the general public at no
291        charge under subsection 6d.
292    
293      A separable portion of the object code, whose source code is excluded
294    from the Corresponding Source as a System Library, need not be
295    included in conveying the object code work.
296    
297      A "User Product" is either (1) a "consumer product", which means any
298    tangible personal property which is normally used for personal, family,
299    or household purposes, or (2) anything designed or sold for incorporation
300    into a dwelling.  In determining whether a product is a consumer product,
301    doubtful cases shall be resolved in favor of coverage.  For a particular
302    product received by a particular user, "normally used" refers to a
303    typical or common use of that class of product, regardless of the status
304    of the particular user or of the way in which the particular user
305    actually uses, or expects or is expected to use, the product.  A product
306    is a consumer product regardless of whether the product has substantial
307    commercial, industrial or non-consumer uses, unless such uses represent
308    the only significant mode of use of the product.
309    
310      "Installation Information" for a User Product means any methods,
311    procedures, authorization keys, or other information required to install
312    and execute modified versions of a covered work in that User Product from
313    a modified version of its Corresponding Source.  The information must
314    suffice to ensure that the continued functioning of the modified object
315    code is in no case prevented or interfered with solely because
316    modification has been made.
317    
318      If you convey an object code work under this section in, or with, or
319    specifically for use in, a User Product, and the conveying occurs as
320    part of a transaction in which the right of possession and use of the
321    User Product is transferred to the recipient in perpetuity or for a
322    fixed term (regardless of how the transaction is characterized), the
323    Corresponding Source conveyed under this section must be accompanied
324    by the Installation Information.  But this requirement does not apply
325    if neither you nor any third party retains the ability to install
326    modified object code on the User Product (for example, the work has
327    been installed in ROM).
328    
329      The requirement to provide Installation Information does not include a
330    requirement to continue to provide support service, warranty, or updates
331    for a work that has been modified or installed by the recipient, or for
332    the User Product in which it has been modified or installed.  Access to a
333    network may be denied when the modification itself materially and
334    adversely affects the operation of the network or violates the rules and
335    protocols for communication across the network.
336    
337      Corresponding Source conveyed, and Installation Information provided,
338    in accord with this section must be in a format that is publicly
339    documented (and with an implementation available to the public in
340    source code form), and must require no special password or key for
341    unpacking, reading or copying.
342    
343      7. Additional Terms.
344    
345      "Additional permissions" are terms that supplement the terms of this
346    License by making exceptions from one or more of its conditions.
347    Additional permissions that are applicable to the entire Program shall
348    be treated as though they were included in this License, to the extent
349    that they are valid under applicable law.  If additional permissions
350    apply only to part of the Program, that part may be used separately
351    under those permissions, but the entire Program remains governed by
352    this License without regard to the additional permissions.
353    
354      When you convey a copy of a covered work, you may at your option
355    remove any additional permissions from that copy, or from any part of
356    it.  (Additional permissions may be written to require their own
357    removal in certain cases when you modify the work.)  You may place
358    additional permissions on material, added by you to a covered work,
359    for which you have or can give appropriate copyright permission.
360    
361      Notwithstanding any other provision of this License, for material you
362    add to a covered work, you may (if authorized by the copyright holders of
363    that material) supplement the terms of this License with terms:
364    
365        a) Disclaiming warranty or limiting liability differently from the
366        terms of sections 15 and 16 of this License; or
367    
368        b) Requiring preservation of specified reasonable legal notices or
369        author attributions in that material or in the Appropriate Legal
370        Notices displayed by works containing it; or
371    
372        c) Prohibiting misrepresentation of the origin of that material, or
373        requiring that modified versions of such material be marked in
374        reasonable ways as different from the original version; or
375    
376        d) Limiting the use for publicity purposes of names of licensors or
377        authors of the material; or
378    
379        e) Declining to grant rights under trademark law for use of some
380        trade names, trademarks, or service marks; or
381    
382        f) Requiring indemnification of licensors and authors of that
383        material by anyone who conveys the material (or modified versions of
384        it) with contractual assumptions of liability to the recipient, for
385        any liability that these contractual assumptions directly impose on
386        those licensors and authors.
387    
388      All other non-permissive additional terms are considered "further
389    restrictions" within the meaning of section 10.  If the Program as you
390    received it, or any part of it, contains a notice stating that it is
391    governed by this License along with a term that is a further
392    restriction, you may remove that term.  If a license document contains
393    a further restriction but permits relicensing or conveying under this
394    License, you may add to a covered work material governed by the terms
395    of that license document, provided that the further restriction does
396    not survive such relicensing or conveying.
397    
398      If you add terms to a covered work in accord with this section, you
399    must place, in the relevant source files, a statement of the
400    additional terms that apply to those files, or a notice indicating
401    where to find the applicable terms.
402    
403      Additional terms, permissive or non-permissive, may be stated in the
404    form of a separately written license, or stated as exceptions;
405    the above requirements apply either way.
406    
407      8. Termination.
408    
409      You may not propagate or modify a covered work except as expressly
410    provided under this License.  Any attempt otherwise to propagate or
411    modify it is void, and will automatically terminate your rights under
412    this License (including any patent licenses granted under the third
413    paragraph of section 11).
414    
415      However, if you cease all violation of this License, then your
416    license from a particular copyright holder is reinstated (a)
417    provisionally, unless and until the copyright holder explicitly and
418    finally terminates your license, and (b) permanently, if the copyright
419    holder fails to notify you of the violation by some reasonable means
420    prior to 60 days after the cessation.
421    
422      Moreover, your license from a particular copyright holder is
423    reinstated permanently if the copyright holder notifies you of the
424    violation by some reasonable means, this is the first time you have
425    received notice of violation of this License (for any work) from that
426    copyright holder, and you cure the violation prior to 30 days after
427    your receipt of the notice.
428    
429      Termination of your rights under this section does not terminate the
430    licenses of parties who have received copies or rights from you under
431    this License.  If your rights have been terminated and not permanently
432    reinstated, you do not qualify to receive new licenses for the same
433    material under section 10.
434    
435      9. Acceptance Not Required for Having Copies.
436    
437      You are not required to accept this License in order to receive or
438    run a copy of the Program.  Ancillary propagation of a covered work
439    occurring solely as a consequence of using peer-to-peer transmission
440    to receive a copy likewise does not require acceptance.  However,
441    nothing other than this License grants you permission to propagate or
442    modify any covered work.  These actions infringe copyright if you do
443    not accept this License.  Therefore, by modifying or propagating a
444    covered work, you indicate your acceptance of this License to do so.
445    
446      10. Automatic Licensing of Downstream Recipients.
447    
448      Each time you convey a covered work, the recipient automatically
449    receives a license from the original licensors, to run, modify and
450    propagate that work, subject to this License.  You are not responsible
451    for enforcing compliance by third parties with this License.
452    
453      An "entity transaction" is a transaction transferring control of an
454    organization, or substantially all assets of one, or subdividing an
455    organization, or merging organizations.  If propagation of a covered
456    work results from an entity transaction, each party to that
457    transaction who receives a copy of the work also receives whatever
458    licenses to the work the party's predecessor in interest had or could
459    give under the previous paragraph, plus a right to possession of the
460    Corresponding Source of the work from the predecessor in interest, if
461    the predecessor has it or can get it with reasonable efforts.
462    
463      You may not impose any further restrictions on the exercise of the
464    rights granted or affirmed under this License.  For example, you may
465    not impose a license fee, royalty, or other charge for exercise of
466    rights granted under this License, and you may not initiate litigation
467    (including a cross-claim or counterclaim in a lawsuit) alleging that
468    any patent claim is infringed by making, using, selling, offering for
469    sale, or importing the Program or any portion of it.
470    
471      11. Patents.
472    
473      A "contributor" is a copyright holder who authorizes use under this
474    License of the Program or a work on which the Program is based.  The
475    work thus licensed is called the contributor's "contributor version".
476    
477      A contributor's "essential patent claims" are all patent claims
478    owned or controlled by the contributor, whether already acquired or
479    hereafter acquired, that would be infringed by some manner, permitted
480    by this License, of making, using, or selling its contributor version,
481    but do not include claims that would be infringed only as a
482    consequence of further modification of the contributor version.  For
483    purposes of this definition, "control" includes the right to grant
484    patent sublicenses in a manner consistent with the requirements of
485    this License.
486    
487      Each contributor grants you a non-exclusive, worldwide, royalty-free
488    patent license under the contributor's essential patent claims, to
489    make, use, sell, offer for sale, import and otherwise run, modify and
490    propagate the contents of its contributor version.
491    
492      In the following three paragraphs, a "patent license" is any express
493    agreement or commitment, however denominated, not to enforce a patent
494    (such as an express permission to practice a patent or covenant not to
495    sue for patent infringement).  To "grant" such a patent license to a
496    party means to make such an agreement or commitment not to enforce a
497    patent against the party.
498    
499      If you convey a covered work, knowingly relying on a patent license,
500    and the Corresponding Source of the work is not available for anyone
501    to copy, free of charge and under the terms of this License, through a
502    publicly available network server or other readily accessible means,
503    then you must either (1) cause the Corresponding Source to be so
504    available, or (2) arrange to deprive yourself of the benefit of the
505    patent license for this particular work, or (3) arrange, in a manner
506    consistent with the requirements of this License, to extend the patent
507    license to downstream recipients.  "Knowingly relying" means you have
508    actual knowledge that, but for the patent license, your conveying the
509    covered work in a country, or your recipient's use of the covered work
510    in a country, would infringe one or more identifiable patents in that
511    country that you have reason to believe are valid.
512    
513      If, pursuant to or in connection with a single transaction or
514    arrangement, you convey, or propagate by procuring conveyance of, a
515    covered work, and grant a patent license to some of the parties
516    receiving the covered work authorizing them to use, propagate, modify
517    or convey a specific copy of the covered work, then the patent license
518    you grant is automatically extended to all recipients of the covered
519    work and works based on it.
520    
521      A patent license is "discriminatory" if it does not include within
522    the scope of its coverage, prohibits the exercise of, or is
523    conditioned on the non-exercise of one or more of the rights that are
524    specifically granted under this License.  You may not convey a covered
525    work if you are a party to an arrangement with a third party that is
526    in the business of distributing software, under which you make payment
527    to the third party based on the extent of your activity of conveying
528    the work, and under which the third party grants, to any of the
529    parties who would receive the covered work from you, a discriminatory
530    patent license (a) in connection with copies of the covered work
531    conveyed by you (or copies made from those copies), or (b) primarily
532    for and in connection with specific products or compilations that
533    contain the covered work, unless you entered into that arrangement,
534    or that patent license was granted, prior to 28 March 2007.
535    
536      Nothing in this License shall be construed as excluding or limiting
537    any implied license or other defenses to infringement that may
538    otherwise be available to you under applicable patent law.
539    
540      12. No Surrender of Others' Freedom.
541    
542      If conditions are imposed on you (whether by court order, agreement or
543    otherwise) that contradict the conditions of this License, they do not
544    excuse you from the conditions of this License.  If you cannot convey a
545    covered work so as to satisfy simultaneously your obligations under this
546    License and any other pertinent obligations, then as a consequence you may
547    not convey it at all.  For example, if you agree to terms that obligate you
548    to collect a royalty for further conveying from those to whom you convey
549    the Program, the only way you could satisfy both those terms and this
550    License would be to refrain entirely from conveying the Program.
551    
552      13. Use with the GNU Affero General Public License.
553    
554      Notwithstanding any other provision of this License, you have
555    permission to link or combine any covered work with a work licensed
556    under version 3 of the GNU Affero General Public License into a single
557    combined work, and to convey the resulting work.  The terms of this
558    License will continue to apply to the part which is the covered work,
559    but the special requirements of the GNU Affero General Public License,
560    section 13, concerning interaction through a network will apply to the
561    combination as such.
562    
563      14. Revised Versions of this License.
564    
565      The Free Software Foundation may publish revised and/or new versions of
566    the GNU General Public License from time to time.  Such new versions will
567    be similar in spirit to the present version, but may differ in detail to
568    address new problems or concerns.
569    
570      Each version is given a distinguishing version number.  If the
571    Program specifies that a certain numbered version of the GNU General
572    Public License "or any later version" applies to it, you have the
573    option of following the terms and conditions either of that numbered
574    version or of any later version published by the Free Software
575    Foundation.  If the Program does not specify a version number of the
576    GNU General Public License, you may choose any version ever published
577    by the Free Software Foundation.
578    
579      If the Program specifies that a proxy can decide which future
580    versions of the GNU General Public License can be used, that proxy's
581    public statement of acceptance of a version permanently authorizes you
582    to choose that version for the Program.
583    
584      Later license versions may give you additional or different
585    permissions.  However, no additional obligations are imposed on any
586    author or copyright holder as a result of your choosing to follow a
587    later version.
588    
589      15. Disclaimer of Warranty.
590    
591      THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
592    APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
593    HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
594    OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
595    THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
596    PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
597    IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
598    ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
599    
600      16. Limitation of Liability.
601    
602      IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
603    WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
604    THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
605    GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
606    USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
607    DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
608    PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
609    EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
610    SUCH DAMAGES.
611    
612      17. Interpretation of Sections 15 and 16.
613    
614      If the disclaimer of warranty and limitation of liability provided
615    above cannot be given local legal effect according to their terms,
616    reviewing courts shall apply local law that most closely approximates
617    an absolute waiver of all civil liability in connection with the
618    Program, unless a warranty or assumption of liability accompanies a
619    copy of the Program in return for a fee.
620    
621                         END OF TERMS AND CONDITIONS
622    
623                How to Apply These Terms to Your New Programs
624    
625      If you develop a new program, and you want it to be of the greatest
626    possible use to the public, the best way to achieve this is to make it
627    free software which everyone can redistribute and change under these terms.
628    
629      To do so, attach the following notices to the program.  It is safest
630    to attach them to the start of each source file to most effectively
631    state the exclusion of warranty; and each file should have at least
632    the "copyright" line and a pointer to where the full notice is found.
633    
634        <one line to give the program's name and a brief idea of what it does.>
635        Copyright (C) <year>  <name of author>
636    
637        This program is free software: you can redistribute it and/or modify
638        it under the terms of the GNU General Public License as published by
639        the Free Software Foundation, either version 3 of the License, or
640        (at your option) any later version.
641    
642        This program is distributed in the hope that it will be useful,
643        but WITHOUT ANY WARRANTY; without even the implied warranty of
644        MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
645        GNU General Public License for more details.
646    
647        You should have received a copy of the GNU General Public License
648        along with this program.  If not, see <http://www.gnu.org/licenses/>.
649    
650  Also add information on how to contact you by electronic and paper mail.  Also add information on how to contact you by electronic and paper mail.
651    
652  If the program is interactive, make it output a short notice like this when it starts in an interactive mode:    If the program does terminal interaction, make it output a short
653    notice like this when it starts in an interactive mode:
654    
655      Gnomovision version 69, Copyright (C) 19yy name of author      <program>  Copyright (C) <year>  <name of author>
656      Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.      This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.

659    
660  The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License.  Of course, the commands you use may be called something other than `show w' and `show c'; they could even be mouse-clicks or menu items--whatever suits your program.  The hypothetical commands `show w' and `show c' should show the appropriate
661    parts of the General Public License.  Of course, your program's commands
662  You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the program, if necessary.  Here is a sample; alter the names:  might be different; for a GUI interface, you would use an "about box".
663    
664  Yoyodyne, Inc., hereby disclaims all copyright interest in the program `Gnomovision' (which makes passes at compilers) written by James Hacker.    You should also get your employer (if you work as a programmer) or school,
665    if any, to sign a "copyright disclaimer" for the program, if necessary.
