     7 The licenses for most software and other practical works are designed to take away your freedom to share and change the works. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change all versions of a program--to make sure it remains free software for all its users. We, the Free Software Foundation, use the GNU General Public License for most of our software; it applies also to any other work released this way by its authors. You can apply it to your programs, too.
     8 chooses the other license.
     8 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 them 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.
     9 -----------------------------------------------------------------------
     9 To protect your rights, we need to prevent others from denying you these rights or asking you to surrender the rights. Therefore, you have certain responsibilities if you distribute copies of the software, or if you modify it: responsibilities to respect the freedom of others.
    10 
    10 For example, if you distribute copies of such a program, whether gratis or for a fee, you must pass on to the recipients the same freedoms that you received. 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.
    11 		    GNU GENERAL PUBLIC LICENSE
    11 Developers that use the GNU GPL protect your rights with two steps: (1) assert copyright on the software, and (2) offer you this License giving you legal permission to copy, distribute and/or modify it.
    12 		       Version 2, June 1991
    12 For the developers' and authors' protection, the GPL clearly explains that there is no warranty for this free software. For both users' and authors' sake, the GPL requires that modified versions be marked as changed, so that their problems will not be attributed erroneously to authors of previous versions.
    13 
    13 Some devices are designed to deny users access to install or run modified versions of the software inside them, although the manufacturer can do so. This is fundamentally incompatible with the aim of protecting users' freedom to change the software. The systematic pattern of such abuse occurs in the area of products for individuals to use, which is precisely where it is most unacceptable. Therefore, we have designed this version of the GPL to prohibit the practice for those products. If such problems arise substantially in other domains, we stand ready to extend this provision to those domains in future versions of the GPL, as needed to protect the freedom of users.

    14 Finally, every program is threatened constantly by software patents. States should not allow patents to restrict development and use of software on general-purpose computers, but in those that do, we wish to avoid the special danger that patents applied to a free program could make it effectively proprietary. To prevent this, the GPL assures that patents cannot be used to render the program non-free.

    17 0. Definitions.
    18 
    18 “This License” refers to version 3 of the GNU General Public License.
    19 			    Preamble
    19 “Copyright” also means copyright-like laws that apply to other kinds of works, such as semiconductor masks.
    20 
    20 “The Program” refers to any copyrightable work licensed under this License. Each licensee is addressed as “you”. “Licensees” and “recipients” may be individuals or organizations.
    21   The licenses for most software are designed to take away your
    21 To “modify” a work means to copy from or adapt all or part of the work in a fashion requiring copyright permission, other than the making of an exact copy. The resulting work is called a “modified version” of the earlier work or a work “based on” the earlier work.

    22 A “covered work” means either the unmodified Program or a work based on the Program.
    23 License is intended to guarantee your freedom to share and change free
    23 To “propagate” a work means to do anything with it that, without permission, would make you directly or secondarily liable for infringement under applicable copyright law, except executing it on a computer or modifying a private copy. Propagation includes copying, distribution (with or without modification), making available to the public, and in some countries other activities as well.

    24 To “convey” a work means any kind of propagation that enables other parties to make or receive copies. Mere interaction with a user through a computer network, with no transfer of a copy, is not conveying.
    25 General Public License applies to most of the Free Software
    25 An interactive user interface displays “Appropriate Legal Notices” to the extent that it includes a convenient and prominently visible feature that (1) displays an appropriate copyright notice, and (2) tells the user that there is no warranty for the work (except to the extent that warranties are provided), that licensees may convey the work under this License, and how to view a copy of this License. If the interface presents a list of user commands or options, such as a menu, a prominent item in the list meets this criterion.

    27 The “source code” for a work means the preferred form of the work for making modifications to it. “Object code” means any non-source form of a work.
    28 the GNU Library General Public License instead.)  You can apply it to
    28 A “Standard Interface” means an interface that either is an official standard defined by a recognized standards body, or, in the case of interfaces specified for a particular programming language, one that is widely used among developers working in that language.
    29 your programs, too.
    29 The “System Libraries” of an executable work include anything, other than the work as a whole, that (a) is included in the normal form of packaging a Major Component, but which is not part of that Major Component, and (b) serves only to enable use of the work with that Major Component, or to implement a Standard Interface for which an implementation is available to the public in source code form. A “Major Component”, in this context, means a major essential component (kernel, window system, and so on) of the specific operating system (if any) on which the executable work runs, or a compiler used to produce the work, or an object code interpreter used to run it.
    30 
    30 The “Corresponding Source” for a work in object code form means all the source code needed to generate, install, and (for an executable work) run the object code and to modify the work, including scripts to control those activities. However, it does not include the work's System Libraries, or general-purpose tools or generally available free programs which are used unmodified in performing those activities but which are not part of the work. For example, Corresponding Source includes interface definition files associated with source files for the work, and the source code for shared libraries and dynamically linked subprograms that the work is specifically designed to require, such as by intimate data communication or control flow between those subprograms and other parts of the work.

    34 All rights granted under this License are granted for the term of copyright on the Program, and are irrevocable provided the stated conditions are met. This License explicitly affirms your unlimited permission to run the unmodified Program. The output from running a covered work is covered by this License only if the output, given its content, constitutes a covered work. This License acknowledges your rights of fair use or other equivalent, as provided by copyright law.
    35 if you want it, that you can change the software or use pieces of it
    35 You may make, run and propagate covered works that you do not convey, without conditions so long as your license otherwise remains in force. You may convey covered works to others for the sole purpose of having them make modifications exclusively for you, or provide you with facilities for running those works, provided that you comply with the terms of this License in conveying all material for which you do not control copyright. Those thus making or running the covered works for you must do so exclusively on your behalf, under your direction and control, on terms that prohibit them from making any copies of your copyrighted material outside their relationship with you.
    36 in new free programs; and that you know you can do these things.
    36 Conveying under any other circumstances is permitted solely under the conditions stated below. Sublicensing is not allowed; section 10 makes it unnecessary.
    37 
    37 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
    38   To protect your rights, we need to make restrictions that forbid
    38 No covered work shall be deemed part of an effective technological measure under any applicable law fulfilling obligations under article 11 of the WIPO copyright treaty adopted on 20 December 1996, or similar laws prohibiting or restricting circumvention of such measures.
    39 anyone to deny you these rights or to ask you to surrender the rights.
    39 When you convey a covered work, you waive any legal power to forbid circumvention of technological measures to the extent such circumvention is effected by exercising rights under this License with respect to the covered work, and you disclaim any intention to limit operation or modification of the work as a means of enforcing, against the work's users, your or third parties' legal rights to forbid circumvention of technological measures.
    40 These restrictions translate to certain responsibilities for you if you
    40 4. Conveying Verbatim Copies.
    41 distribute copies of the software, or if you modify it.
    41 You may convey 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; keep intact all notices stating that this License and any non-permissive terms added in accord with section 7 apply to the code; keep intact all notices of the absence of any warranty; and give all recipients a copy of this License along with the Program.
    42 
    42 You may charge any price or no price for each copy that you convey, and you may offer support or warranty protection for a fee.
    43   For example, if you distribute copies of such a program, whether

    44 gratis or for a fee, you must give the recipients all the rights that
    44 You may convey a work based on the Program, or the modifications to produce it from the Program, in the form of source code under the terms of section 4, provided that you also meet all of these conditions:

    47 rights.
    47 c) You must license the entire work, as a whole, under this License to anyone who comes into possession of a copy. This License will therefore apply, along with any applicable section 7 additional terms, to the whole of the work, and all its parts, regardless of how they are packaged. This License gives no permission to license the work in any other way, but it does not invalidate such permission if you have separately received it. 
    48 
    48 d) If the work has interactive user interfaces, each must display Appropriate Legal Notices; however, if the Program has interactive interfaces that do not display Appropriate Legal Notices, your work need not make them do so. 
    49   We protect your rights with two steps: (1) copyright the software, and
    49 A compilation of a covered work with other separate and independent works, which are not by their nature extensions of the covered work, and which are not combined with it such as to form a larger program, in or on a volume of a storage or distribution medium, is called an “aggregate” if the compilation and its resulting copyright are not used to limit the access or legal rights of the compilation's users beyond what the individual works permit. Inclusion of a covered work in an aggregate does not cause this License to apply to the other parts of the aggregate.
    50 (2) offer you this license which gives you legal permission to copy,
    50 6. Conveying Non-Source Forms.
    51 distribute and/or modify the software.
    51 You may convey a covered work in object code form under the terms of sections 4 and 5, provided that you also convey the machine-readable Corresponding Source under the terms of this License, in one of these ways:
    52 
    52 a) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by the Corresponding Source fixed on a durable physical medium customarily used for software interchange. 
    53   Also, for each author's protection and ours, we want to make certain
    53 b) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by a written offer, valid for at least three years and valid for as long as you offer spare parts or customer support for that product model, to give anyone who possesses the object code either (1) a copy of the Corresponding Source for all the software in the product that is covered by this License, on a durable physical medium customarily used for software interchange, for a price no more than your reasonable cost of physically performing this conveying of source, or (2) access to copy the Corresponding Source from a network server at no charge. 
    54 that everyone understands that there is no warranty for this free
    54 c) Convey individual copies of the object code with a copy of the written offer to provide the Corresponding Source. This alternative is allowed only occasionally and noncommercially, and only if you received the object code with such an offer, in accord with subsection 6b. 
    55 software.  If the software is modified by someone else and passed on, we
    55 d) Convey the object code by offering access from a designated place (gratis or for a charge), and offer equivalent access to the Corresponding Source in the same way through the same place at no further charge. You need not require recipients to copy the Corresponding Source along with the object code. If the place to copy the object code is a network server, the Corresponding Source may be on a different server (operated by you or a third party) that supports equivalent copying facilities, provided you maintain clear directions next to the object code saying where to find the Corresponding Source. Regardless of what server hosts the Corresponding Source, you remain obligated to ensure that it is available for as long as needed to satisfy these requirements. 
    56 want its recipients to know that what they have is not the original, so
    56 e) Convey the object code using peer-to-peer transmission, provided you inform other peers where the object code and Corresponding Source of the work are being offered to the general public at no charge under subsection 6d.

    58 authors' reputations.
    58 A “User Product” is either (1) a “consumer product”, which means any tangible personal property which is normally used for personal, family, or household purposes, or (2) anything designed or sold for incorporation into a dwelling. In determining whether a product is a consumer product, doubtful cases shall be resolved in favor of coverage. For a particular product received by a particular user, “normally used” refers to a typical or common use of that class of product, regardless of the status of the particular user or of the way in which the particular user actually uses, or expects or is expected to use, the product. A product is a consumer product regardless of whether the product has substantial commercial, industrial or non-consumer uses, unless such uses represent the only significant mode of use of the product.
    59 
    59 “Installation Information” for a User Product means any methods, procedures, authorization keys, or other information required to install and execute modified versions of a covered work in that User Product from a modified version of its Corresponding Source. The information must suffice to ensure that the continued functioning of the modified object code is in no case prevented or interfered with solely because modification has been made.
    60   Finally, any free program is threatened constantly by software
    60 If you convey an object code work under this section in, or with, or specifically for use in, a User Product, and the conveying occurs as part of a transaction in which the right of possession and use of the User Product is transferred to the recipient in perpetuity or for a fixed term (regardless of how the transaction is characterized), the Corresponding Source conveyed under this section must be accompanied by the Installation Information. But this requirement does not apply if neither you nor any third party retains the ability to install modified object code on the User Product (for example, the work has been installed in ROM).

    61 The requirement to provide Installation Information does not include a requirement to continue to provide support service, warranty, or updates for a work that has been modified or installed by the recipient, or for the User Product in which it has been modified or installed.

    64 patent must be licensed for everyone's free use or not licensed at all.
    64 “Additional permissions” are terms that supplement the terms of this License by making exceptions from one or more of its conditions. Additional permissions that are applicable to the entire Program shall be treated as though they were included in this License, to the extent that they are valid under applicable law. If additional permissions apply only to part of the Program, that part may be used separately under those permissions, but the entire Program remains governed by this License without regard to the additional permissions.
    65 
    65 When you convey a copy of a covered work, you may at your option remove any additional permissions from that copy, or from any part of it. (Additional permissions may be written to require their own removal in certain cases when you modify the work.) You may place additional permissions on material, added by you to a covered work, for which you have or can give appropriate copyright permission.
    66   The precise terms and conditions for copying, distribution and
    66 Notwithstanding any other provision of this License, for material you add to a covered work, you may (if authorized by the copyright holders of that material) supplement the terms of this License with terms:

    73 a notice placed by the copyright holder saying it may be distributed
    73 All other non-permissive additional terms are considered “further restrictions” within the meaning of section 10. If the Program as you received it, or any part of it, contains a notice stating that it is governed by this License along with a term that is a further restriction, you may remove that term. If a license document contains a further restriction but permits relicensing or conveying under this License, you may add to a covered work material governed by the terms of that license document, provided that the further restriction does not survive such relicensing or conveying.

    80 the term "modification".)  Each licensee is addressed as "you".
    80 Termination of your rights under this section does not terminate the licenses of parties who have received copies or rights from you under this License. If your rights have been terminated and not permanently reinstated, you do not qualify to receive new licenses for the same material under section 10.

    81 9. Acceptance Not Required for Having Copies.
    82 Activities other than copying, distribution and modification are not
    82 You are not required to accept this License in order to receive or run a copy of the Program. Ancillary propagation of a covered work occurring solely as a consequence of using peer-to-peer transmission to receive a copy likewise does not require acceptance. However, nothing other than this License grants you permission to propagate or modify any covered work. These actions infringe copyright if you do not accept this License. Therefore, by modifying or propagating a covered work, you indicate your acceptance of this License to do so.

    85 An “entity transaction” is a transaction transferring control of an organization, or substantially all assets of one, or subdividing an organization, or merging organizations. If propagation of a covered work results from an entity transaction, each party to that transaction who receives a copy of the work also receives whatever licenses to the work the party's predecessor in interest had or could give under the previous paragraph, plus a right to possession of the Corresponding Source of the work from the predecessor in interest, if the predecessor has it or can get it with reasonable efforts.
    86 Program (independent of having been made by running the Program).
    86 You may not impose any further restrictions on the exercise of the rights granted or affirmed under this License. For example, you may not impose a license fee, royalty, or other charge for exercise of rights granted under this License, and you may not initiate litigation (including a cross-claim or counterclaim in a lawsuit) alleging that any patent claim is infringed by making, using, selling, offering for sale, or importing the Program or any portion of it.
    87 Whether that is true depends on what the Program does.
    87 11. Patents.
    88 
    88 A “contributor” is a copyright holder who authorizes use under this License of the Program or a work on which the Program is based. The work thus licensed is called the contributor's “contributor version”.
    89   1. You may copy and distribute verbatim copies of the Program's
    89 A contributor's “essential patent claims” are all patent claims owned or controlled by the contributor, whether already acquired or hereafter acquired, that would be infringed by some manner, permitted by this License, of making, using, or selling its contributor version, but do not include claims that would be infringed only as a consequence of further modification of the contributor version. For purposes of this definition, “control” includes the right to grant patent sublicenses in a manner consistent with the requirements of this License.

    91 In the following three paragraphs, a “patent license” is any express agreement or commitment, however denominated, not to enforce a patent (such as an express permission to practice a patent or covenant not to sue for patent infringement). To “grant” such a patent license to a party means to make such an agreement or commitment not to enforce a patent against the party.

    92 If you convey a covered work, knowingly relying on a patent license, and the Corresponding Source of the work is not available for anyone to copy, free of charge and under the terms of this License, through a publicly available network server or other readily accessible means, then you must either (1) cause the Corresponding Source to be so available, or (2) arrange to deprive yourself of the benefit of the patent license for this particular work, or (3) arrange, in a manner consistent with the requirements of this License, to extend the patent license to downstream recipients. “Knowingly relying” means you have actual knowledge that, but for the patent license, your conveying the covered work in a country, or your recipient's use of the covered work in a country, would infringe one or more identifiable patents in that country that you have reason to believe are valid.

    93 If, pursuant to or in connection with a single transaction or arrangement, you convey, or propagate by procuring conveyance of, a covered work, and grant a patent license to some of the parties receiving the covered work authorizing them to use, propagate, modify or convey a specific copy of the covered work, then the patent license you grant is automatically extended to all recipients of the covered work and works based on it.
    94 and give any other recipients of the Program a copy of this License
    94 A patent license is “discriminatory” if it does not include within the scope of its coverage, prohibits the exercise of, or is conditioned on the non-exercise of one or more of the rights that are specifically granted under this License. You may not convey a covered work if you are a party to an arrangement with a third party that is in the business of distributing software, under which you make payment to the third party based on the extent of your activity of conveying the work, and under which the third party grants, to any of the parties who would receive the covered work from you, a discriminatory patent license (a) in connection with copies of the covered work conveyed by you (or copies made from those copies), or (b) primarily for and in connection with specific products or compilations that contain the covered work, unless you entered into that arrangement, or that patent license was granted, prior to 28 March 2007.

    97 You may charge a fee for the physical act of transferring a copy, and
    97 If 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 convey a covered work so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not convey it at all. For example, if you agree to terms that obligate you to collect a royalty for further conveying from those to whom you convey the Program, the only way you could satisfy both those terms and this License would be to refrain entirely from conveying the Program.
    98 you may at your option offer warranty protection in exchange for a fee.
    98 13. Use with the GNU Affero General Public License.
    99 
    99 Notwithstanding any other provision of this License, you have permission to link or combine any covered work with a work licensed under version 3 of the GNU Affero General Public License into a single combined work, and to convey the resulting work. The terms of this License will continue to apply to the part which is the covered work, but the special requirements of the GNU Affero General Public License, section 13, concerning interaction through a network will apply to the combination as such.
   100   2. You may modify your copy or copies of the Program or any portion

   101 The Free Software Foundation may publish revised and/or new versions of the GNU 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.
   102 distribute such modifications or work under the terms of Section 1
   102 Each version is given a distinguishing version number. If the Program specifies that a certain numbered version of the GNU General Public License “or any later version” applies to it, you have the option of following the terms and conditions either of that numbered version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of the GNU General Public License, you may choose any version ever published by the Free Software Foundation.
   103 above, provided that you also meet all of these conditions:
   103 If the Program specifies that a proxy can decide which future versions of the GNU General Public License can be used, that proxy's public statement of acceptance of a version permanently authorizes you to choose that version for the Program.
   104 
   104 Later license versions may give you additional or different permissions. However, no additional obligations are imposed on any author or copyright holder as a result of your choosing to follow a later version.
   105     a) You must cause the modified files to carry prominent notices

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.

   112 
   112 How to Apply These Terms to Your New Programs
   113     c) If the modified program normally reads commands interactively
   113 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.
   114     when run, you must cause it, when started running for such
   114 To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively state the exclusion of warranty; and each file should have at least the “copyright” line and a pointer to where the full notice is found.
   115     interactive use in the most ordinary way, to print or display an
       
   116     announcement including an appropriate copyright notice and a
       
   117     notice that there is no warranty (or else, saying that you provide
       
   118     a warranty) and that users may redistribute the program under
       
   119     these conditions, and telling the user how to view a copy of this
       
   120     License.  (Exception: if the Program itself is interactive but
       
   121     does not normally print such an announcement, your work based on
       
   122     the Program is not required to print an announcement.)
       
   123 
       
   124 These requirements apply to the modified work as a whole.  If
       
   125 identifiable sections of that work are not derived from the Program,
       
   126 and can be reasonably considered independent and separate works in
       
   127 themselves, then this License, and its terms, do not apply to those
       
   128 sections when you distribute them as separate works.  But when you
       
   129 distribute the same sections as part of a whole which is a work based
       
   130 on the Program, the distribution of the whole must be on the terms of
       
   131 this License, whose permissions for other licensees extend to the
       
   132 entire whole, and thus to each and every part regardless of who wrote it.
       
   133 
       
   134 Thus, it is not the intent of this section to claim rights or contest
       
   135 your rights to work written entirely by you; rather, the intent is to
       
   136 exercise the right to control the distribution of derivative or
       
   137 collective works based on the Program.
       
   138 
       
   139 In addition, mere aggregation of another work not based on the Program
       
   140 with the Program (or with a work based on the Program) on a volume of
       
   141 a storage or distribution medium does not bring the other work under
       
   142 the scope of this License.
       
   143 
       
   144   3. You may copy and distribute the Program (or a work based on it,
       
   145 under Section 2) in object code or executable form under the terms of
       
   146 Sections 1 and 2 above provided that you also do one of the following:
       
   147 
       
   148     a) Accompany it with the complete corresponding machine-readable
       
   149     source code, which must be distributed under the terms of Sections
       
   150     1 and 2 above on a medium customarily used for software interchange; or,
       
   151 
       
   152     b) Accompany it with a written offer, valid for at least three
       
   153     years, to give any third party, for a charge no more than your
       
   154     cost of physically performing source distribution, a complete
       
   155     machine-readable copy of the corresponding source code, to be
       
   156     distributed under the terms of Sections 1 and 2 above on a medium
       
   157     customarily used for software interchange; or,
       
   158 
       
   159     c) Accompany it with the information you received as to the offer
       
   160     to distribute corresponding source code.  (This alternative is
       
   161     allowed only for noncommercial distribution and only if you
       
   162     received the program in object code or executable form with such
       
   163     an offer, in accord with Subsection b above.)
       
   164 
       
   165 The source code for a work means the preferred form of the work for
       
   166 making modifications to it.  For an executable work, complete source
       
   167 code means all the source code for all modules it contains, plus any
       
   168 associated interface definition files, plus the scripts used to
       
   169 control compilation and installation of the executable.  However, as a
       
   170 special exception, the source code distributed need not include
       
   171 anything that is normally distributed (in either source or binary
       
   172 form) with the major components (compiler, kernel, and so on) of the
       
   173 operating system on which the executable runs, unless that component
       
   174 itself accompanies the executable.
       
   175 
       
   176 If distribution of executable or object code is made by offering
       
   177 access to copy from a designated place, then offering equivalent
       
   178 access to copy the source code from the same place counts as
       
   179 distribution of the source code, even though third parties are not
       
   180 compelled to copy the source along with the object code.
       
   181 
       
   182   4. You may not copy, modify, sublicense, or distribute the Program
       
   183 except as expressly provided under this License.  Any attempt
       
   184 otherwise to copy, modify, sublicense or distribute the Program is
       
   185 void, and will automatically terminate your rights under this License.
       
   186 However, parties who have received copies, or rights, from you under
       
   187 this License will not have their licenses terminated so long as such
       
   188 parties remain in full compliance.
       
   189 
       
   190   5. You are not required to accept this License, since you have not
       
   191 signed it.  However, nothing else grants you permission to modify or
       
   192 distribute the Program or its derivative works.  These actions are
       
   193 prohibited by law if you do not accept this License.  Therefore, by
       
   194 modifying or distributing the Program (or any work based on the
       
   195 Program), you indicate your acceptance of this License to do so, and
       
   196 all its terms and conditions for copying, distributing or modifying
       
   197 the Program or works based on it.
       
   198 
       
   199   6. Each time you redistribute the Program (or any work based on the
       
   200 Program), the recipient automatically receives a license from the
       
   201 original licensor to copy, distribute or modify the Program subject to
       
   202 these terms and conditions.  You may not impose any further
       
   203 restrictions on the recipients' exercise of the rights granted herein.
       
   204 You are not responsible for enforcing compliance by third parties to
       
   205 this License.
       
   206 
       
   207   7. If, as a consequence of a court judgment or allegation of patent
       
   208 infringement or for any other reason (not limited to patent issues),
       
   209 conditions are imposed on you (whether by court order, agreement or
       
   210 otherwise) that contradict the conditions of this License, they do not
       
   211 excuse you from the conditions of this License.  If you cannot
       
   212 distribute so as to satisfy simultaneously your obligations under this
       
   213 License and any other pertinent obligations, then as a consequence you
       
   214 may not distribute the Program at all.  For example, if a patent
       
   215 license would not permit royalty-free redistribution of the Program by
       
   216 all those who receive copies directly or indirectly through you, then
       
   217 the only way you could satisfy both it and this License would be to
       
   218 refrain entirely from distribution of the Program.
       
   219 
       
   220 If any portion of this section is held invalid or unenforceable under
       
   221 any particular circumstance, the balance of the section is intended to
       
   222 apply and the section as a whole is intended to apply in other
       
   223 circumstances.
       
   224 
       
   225 It is not the purpose of this section to induce you to infringe any
       
   226 patents or other property right claims or to contest validity of any
       
   227 such claims; this section has the sole purpose of protecting the
       
   228 integrity of the free software distribution system, which is
       
   229 implemented by public license practices.  Many people have made
       
   230 generous contributions to the wide range of software distributed
       
   231 through that system in reliance on consistent application of that
       
   232 system; it is up to the author/donor to decide if he or she is willing
       
   233 to distribute software through any other system and a licensee cannot
       
   234 impose that choice.
       
   235 
       
   236 This section is intended to make thoroughly clear what is believed to
       
   237 be a consequence of the rest of this License.
       
   238 
       
   239   8. If the distribution and/or use of the Program is restricted in
       
   240 certain countries either by patents or by copyrighted interfaces, the
       
   241 original copyright holder who places the Program under this License
       
   242 may add an explicit geographical distribution limitation excluding
       
   243 those countries, so that distribution is permitted only in or among
       
   244 countries not thus excluded.  In such case, this License incorporates
       
   245 the limitation as if written in the body of this License.
       
   246 
       
   247   9. The Free Software Foundation may publish revised and/or new versions
       
   248 of the General Public License from time to time.  Such new versions will
       
   249 be similar in spirit to the present version, but may differ in detail to
       
   250 address new problems or concerns.
       
   251 
       
   252 Each version is given a distinguishing version number.  If the Program
       
   253 specifies a version number of this License which applies to it and "any
       
   254 later version", you have the option of following the terms and conditions
       
   255 either of that version or of any later version published by the Free
       
   256 Software Foundation.  If the Program does not specify a version number of
       
   257 this License, you may choose any version ever published by the Free Software
       
   258 Foundation.
       
   259 
       
   260   10. If you wish to incorporate parts of the Program into other free
       
   261 programs whose distribution conditions are different, write to the author
       
   262 to ask for permission.  For software which is copyrighted by the Free
       
   263 Software Foundation, write to the Free Software Foundation; we sometimes
       
   264 make exceptions for this.  Our decision will be guided by the two goals
       
   265 of preserving the free status of all derivatives of our free software and
       
   266 of promoting the sharing and reuse of software generally.
       
   267 
       
   268 			    NO WARRANTY
       
   269 
       
   270   11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
       
   271 FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
       
   272 OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
       
   273 PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
       
   274 OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
       
   275 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
       
   276 TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
       
   277 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
       
   278 REPAIR OR CORRECTION.
       
   279 
       
   280   12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
       
   281 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
       
   282 REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
       
   283 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
       
   284 OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
       
   285 TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
       
   286 YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
       
   287 PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
       
   288 POSSIBILITY OF SUCH DAMAGES.

   292 	    How to Apply These Terms to Your New Programs
       
   293 
       
   294   If you develop a new program, and you want it to be of the greatest
       
   295 possible use to the public, the best way to achieve this is to make it
       
   296 free software which everyone can redistribute and change under these terms.
       
   297 
       
   298   To do so, attach the following notices to the program.  It is safest
       
   299 to attach them to the start of each source file to most effectively
       
   300 convey the exclusion of warranty; and each file should have at least
       
   301 the "copyright" line and a pointer to where the full notice is found.

   148 1. APPLICABILITY AND DEFINITIONS
   388 
   149 This License applies to any manual or other work, in any medium, that contains a notice placed by the copyright holder saying it can be distributed under the terms of this License. Such a notice grants a world-wide, royalty-free license, unlimited in duration, to use that work under the conditions stated herein. The "Document", below, refers to any such manual or work. Any member of the public is a licensee, and is addressed as "you". You accept the license if you copy, modify or distribute the work in a way requiring permission under copyright law.
   389 This License applies to any manual or other work that contains a
   150 A "Modified Version" of the Document means any work containing the Document or a portion of it, either copied verbatim, or with modifications and/or translated into another language.
   390 notice placed by the copyright holder saying it can be distributed
   151 A "Secondary Section" is a named appendix or a front-matter section of the Document that deals exclusively with the relationship of the publishers or authors of the Document to the Document's overall subject (or to related matters) and contains nothing that could fall directly within that overall subject. (Thus, if the Document is in part a textbook of mathematics, a Secondary Section may not explain any mathematics.) The relationship could be a matter of historical connection with the subject or with related matters, or of legal, commercial, philosophical, ethical or political position regarding them.
   391 under the terms of this License.  The "Document", below, refers to any
   152 The "Invariant Sections" are certain Secondary Sections whose titles are designated, as being those of Invariant Sections, in the notice that says that the Document is released under this License. If a section does not fit the above definition of Secondary then it is not allowed to be designated as Invariant. The Document may contain zero Invariant Sections. If the Document does not identify any Invariant Sections then there are none.
   392 such manual or work.  Any member of the public is a licensee, and is
   153 The "Cover Texts" are certain short passages of text that are listed, as Front-Cover Texts or Back-Cover Texts, in the notice that says that the Document is released under this License. A Front-Cover Text may be at most 5 words, and a Back-Cover Text may be at most 25 words.
   393 addressed as "you".
   154 A "Transparent" copy of the Document means a machine-readable copy, represented in a format whose specification is available to the general public, that is suitable for revising the document straightforwardly with generic text editors or (for images composed of pixels) generic paint programs or (for drawings) some widely available drawing editor, and that is suitable for input to text formatters or for automatic translation to a variety of formats suitable for input to text formatters. A copy made in an otherwise Transparent file format whose markup, or absence of markup, has been arranged to thwart or discourage subsequent modification by readers is not Transparent. An image format is not Transparent if used for any substantial amount of text. A copy that is not "Transparent" is called "Opaque".
   394 
   155 Examples of suitable formats for Transparent copies include plain ASCII without markup, Texinfo input format, LaTeX input format, SGML or XML using a publicly available DTD, and standard-conforming simple HTML, PostScript or PDF designed for human modification. Examples of transparent image formats include PNG, XCF and JPG. Opaque formats include proprietary formats that can be read and edited only by proprietary word processors, SGML or XML for which the DTD and/or processing tools are not generally available, and the machine-generated HTML, PostScript or PDF produced by some word processors for output purposes only.
   395 A "Modified Version" of the Document means any work containing the
   156 The "Title Page" means, for a printed book, the title page itself, plus such following pages as are needed to hold, legibly, the material this License requires to appear in the title page. For works in formats which do not have any title page as such, "Title Page" means the text near the most prominent appearance of the work's title, preceding the beginning of the body of the text.
   396 Document or a portion of it, either copied verbatim, or with
   157 The "publisher" means any person or entity that distributes copies of the Document to the public.
   397 modifications and/or translated into another language.
   158 A section "Entitled XYZ" means a named subunit of the Document whose title either is precisely XYZ or contains XYZ in parentheses following text that translates XYZ in another language. (Here XYZ stands for a specific section name mentioned below, such as "Acknowledgements", "Dedications", "Endorsements", or "History".) To "Preserve the Title" of such a section when you modify the Document means that it remains a section "Entitled XYZ" according to this definition.
   398 
   159 The Document may include Warranty Disclaimers next to the notice which states that this License applies to the Document. These Warranty Disclaimers are considered to be included by reference in this License, but only as regards disclaiming warranties: any other implication that these Warranty Disclaimers may have is void and has no effect on the meaning of this License.
   399 A "Secondary Section" is a named appendix or a front-matter section of
       
   400 the Document that deals exclusively with the relationship of the
       
   401 publishers or authors of the Document to the Document's overall subject
       
   402 (or to related matters) and contains nothing that could fall directly
       
   403 within that overall subject.  (For example, if the Document is in part a
       
   404 textbook of mathematics, a Secondary Section may not explain any
       
   405 mathematics.)  The relationship could be a matter of historical
       
   406 connection with the subject or with related matters, or of legal,
       
   407 commercial, philosophical, ethical or political position regarding
       
   408 them.
       
   409 
       
   410 The "Invariant Sections" are certain Secondary Sections whose titles
       
   411 are designated, as being those of Invariant Sections, in the notice
       
   412 that says that the Document is released under this License.
       
   413 
       
   414 The "Cover Texts" are certain short passages of text that are listed,
       
   415 as Front-Cover Texts or Back-Cover Texts, in the notice that says that
       
   416 the Document is released under this License.
       
   417 
       
   418 A "Transparent" copy of the Document means a machine-readable copy,
       
   419 represented in a format whose specification is available to the
       
   420 general public, whose contents can be viewed and edited directly and
       
   421 straightforwardly with generic text editors or (for images composed of
       
   422 pixels) generic paint programs or (for drawings) some widely available
       
   423 drawing editor, and that is suitable for input to text formatters or
       
   424 for automatic translation to a variety of formats suitable for input
       
   425 to text formatters.  A copy made in an otherwise Transparent file
       
   426 format whose markup has been designed to thwart or discourage
       
   427 subsequent modification by readers is not Transparent.  A copy that is
       
   428 not "Transparent" is called "Opaque".
       
   429 
       
   430 Examples of suitable formats for Transparent copies include plain
       
   431 ASCII without markup, Texinfo input format, LaTeX input format, SGML
       
   432 or XML using a publicly available DTD, and standard-conforming simple
       
   433 HTML designed for human modification.  Opaque formats include
       
   434 PostScript, PDF, proprietary formats that can be read and edited only
       
   435 by proprietary word processors, SGML or XML for which the DTD and/or
       
   436 processing tools are not generally available, and the
       
   437 machine-generated HTML produced by some word processors for output
       
   438 purposes only.
       
   439 
       
   440 The "Title Page" means, for a printed book, the title page itself,
       
   441 plus such following pages as are needed to hold, legibly, the material
       
   442 this License requires to appear in the title page.  For works in
       
   443 formats which do not have any title page as such, "Title Page" means
       
   444 the text near the most prominent appearance of the work's title,
       
   445 preceding the beginning of the body of the text.

   449 
   161 You may copy and distribute the Document in any medium, either commercially or noncommercially, provided that this License, the copyright notices, and the license notice saying this License applies to the Document are reproduced in all copies, and that you add no other conditions whatsoever to those of this License. You may not use technical measures to obstruct or control the reading or further copying of the copies you make or distribute. However, you may accept compensation in exchange for copies. If you distribute a large enough number of copies you must also follow the conditions in section 3.
   450 You may copy and distribute the Document in any medium, either
   162 You may also lend copies, under the same conditions stated above, and you may publicly display copies.
   451 commercially or noncommercially, provided that this License, the
       
   452 copyright notices, and the license notice saying this License applies
       
   453 to the Document are reproduced in all copies, and that you add no other
       
   454 conditions whatsoever to those of this License.  You may not use
       
   455 technical measures to obstruct or control the reading or further
       
   456 copying of the copies you make or distribute.  However, you may accept
       
   457 compensation in exchange for copies.  If you distribute a large enough
       
   458 number of copies you must also follow the conditions in section 3.
       
   459 
       
   460 You may also lend copies, under the same conditions stated above, and
       
   461 you may publicly display copies.

   464 3. COPYING IN QUANTITY
   163 3. COPYING IN QUANTITY
   465 
   164 If you publish printed copies (or copies in media that commonly have printed covers) of the Document, numbering more than 100, and the Document's license notice requires Cover Texts, you must enclose the copies in covers that carry, clearly and legibly, all these Cover Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on the back cover. Both covers must also clearly and legibly identify you as the publisher of these copies. The front cover must present the full title with all words of the title equally prominent and visible. You may add other material on the covers in addition. Copying with changes limited to the covers, as long as they preserve the title of the Document and satisfy these conditions, can be treated as verbatim copying in other respects.
   466 If you publish printed copies of the Document numbering more than 100,
   165 If the required texts for either cover are too voluminous to fit legibly, you should put the first ones listed (as many as fit reasonably) on the actual cover, and continue the rest onto adjacent pages.
   467 and the Document's license notice requires Cover Texts, you must enclose
   166 If you publish or distribute Opaque copies of the Document numbering more than 100, you must either include a machine-readable Transparent copy along with each Opaque copy, or state in or with each Opaque copy a computer-network location from which the general network-using public has access to download using public-standard network protocols a complete Transparent copy of the Document, free of added material. If you use the latter option, you must take reasonably prudent steps, when you begin distribution of Opaque copies in quantity, to ensure that this Transparent copy will remain thus accessible at the stated location until at least one year after the last time you distribute an Opaque copy (directly or through your agents or retailers) of that edition to the public.

   469 Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
       
   470 the back cover.  Both covers must also clearly and legibly identify
       
   471 you as the publisher of these copies.  The front cover must present
       
   472 the full title with all words of the title equally prominent and
       
   473 visible.  You may add other material on the covers in addition.
       
   474 Copying with changes limited to the covers, as long as they preserve
       
   475 the title of the Document and satisfy these conditions, can be treated
       
   476 as verbatim copying in other respects.
       
   477 
       
   478 If the required texts for either cover are too voluminous to fit
       
   479 legibly, you should put the first ones listed (as many as fit
       
   480 reasonably) on the actual cover, and continue the rest onto adjacent
       
   481 pages.
       
   482 
       
   483 If you publish or distribute Opaque copies of the Document numbering
       
   484 more than 100, you must either include a machine-readable Transparent
       
   485 copy along with each Opaque copy, or state in or with each Opaque copy
       
   486 a publicly-accessible computer-network location containing a complete
       
   487 Transparent copy of the Document, free of added material, which the
       
   488 general network-using public has access to download anonymously at no
       
   489 charge using public-standard network protocols.  If you use the latter
       
   490 option, you must take reasonably prudent steps, when you begin
       
   491 distribution of Opaque copies in quantity, to ensure that this
       
   492 Transparent copy will remain thus accessible at the stated location
       
   493 until at least one year after the last time you distribute an Opaque
       
   494 copy (directly or through your agents or retailers) of that edition to
       
   495 the public.
       
   496 
       
   497 It is requested, but not required, that you contact the authors of the

   169 You may copy and distribute a Modified Version of the Document under the conditions of sections 2 and 3 above, provided that you release the Modified Version under precisely this License, with the Modified Version filling the role of the Document, thus licensing distribution and modification of the Modified Version to whoever possesses a copy of it. In addition, you must do these things in the Modified Version:
   504 You may copy and distribute a Modified Version of the Document under

   187 You may add a passage of up to five words as a Front-Cover Text, and a passage of up to 25 words as a Back-Cover Text, to the end of the list of Cover Texts in the Modified Version. Only one passage of Front-Cover Text and one of Back-Cover Text may be added by (or through arrangements made by) any one entity. If the Document already includes a cover text for the same cover, previously added by you or by arrangement made by the same entity you are acting on behalf of, you may not add another; but you may replace the old one, on explicit permission from the previous publisher that added the old one.

   535    stating the title, year, authors, and publisher of the Document as
       
   536    given on its Title Page, then add an item describing the Modified
       
   537    Version as stated in the previous sentence.
       
   538 J. Preserve the network location, if any, given in the Document for
       
   539    public access to a Transparent copy of the Document, and likewise
       
   540    the network locations given in the Document for previous versions
       
   541    it was based on.  These may be placed in the "History" section.
       
   542    You may omit a network location for a work that was published at
       
   543    least four years before the Document itself, or if the original
       
   544    publisher of the version it refers to gives permission.
       
   545 K. In any section entitled "Acknowledgements" or "Dedications",
       
   546    preserve the section's title, and preserve in the section all the
       
   547    substance and tone of each of the contributor acknowledgements
       
   548    and/or dedications given therein.
       
   549 L. Preserve all the Invariant Sections of the Document,
       
   550    unaltered in their text and in their titles.  Section numbers
       
   551    or the equivalent are not considered part of the section titles.
       
   552 M. Delete any section entitled "Endorsements".  Such a section
       
   553    may not be included in the Modified Version.
       
   554 N. Do not retitle any existing section as "Endorsements"
       
   555    or to conflict in title with any Invariant Section.
       
   556 
       
   557 If the Modified Version includes new front-matter sections or
       
   558 appendices that qualify as Secondary Sections and contain no material
       
   559 copied from the Document, you may at your option designate some or all
       
   560 of these sections as invariant.  To do this, add their titles to the
       
   561 list of Invariant Sections in the Modified Version's license notice.
       
   562 These titles must be distinct from any other section titles.
       
   563 
       
   564 You may add a section entitled "Endorsements", provided it contains
       
   565 nothing but endorsements of your Modified Version by various
       
   566 parties--for example, statements of peer review or that the text has
       
   567 been approved by an organization as the authoritative definition of a
       
   568 standard.
       
   569 
       
   570 You may add a passage of up to five words as a Front-Cover Text, and a
       
   571 passage of up to 25 words as a Back-Cover Text, to the end of the list
       
   572 of Cover Texts in the Modified Version.  Only one passage of
       
   573 Front-Cover Text and one of Back-Cover Text may be added by (or
       
   574 through arrangements made by) any one entity.  If the Document already
       
   575 includes a cover text for the same cover, previously added by you or
       
   576 by arrangement made by the same entity you are acting on behalf of,
       
   577 you may not add another; but you may replace the old one, on explicit
       
   578 permission from the previous publisher that added the old one.
       
   579 
       
   580 The author(s) and publisher(s) of the Document do not by this License
       
   581 give permission to use their names for publicity for or to assert or
       
   582 imply endorsement of any Modified Version.
