     31<h1><a name="preamble"></a>Preamble</h1>
     32
     33<p>The GNU General Public License is a free, copyleft license for
     34software and other kinds of works.</p>
     35
     36<p>The licenses for most software and other practical works are designed
     37to take away your freedom to share and change the works.  By contrast,
     38the GNU General Public License is intended to guarantee your freedom to
     39share and change all versions of a program--to make sure it remains free
     40software for all its users.  We, the Free Software Foundation, use the
     41GNU General Public License for most of our software; it applies also to
     42any other work released this way by its authors.  You can apply it to
     43your programs, too.</p>
     44
     45<p>When we speak of free software, we are referring to freedom, not
    7046price.  Our General Public Licenses are designed to make sure that you
    7147have the freedom to distribute copies of free software (and charge for
    72 this service if you wish), that you receive source code or can get it
    73 if you want it, that you can change the software or use pieces of it
    74 in new free programs; and that you know you can do these things.
    75 
    76 </P>
    77 <P>
    78   To protect your rights, we need to make restrictions that forbid
    79 anyone to deny you these rights or to ask you to surrender the rights.
    80 These restrictions translate to certain responsibilities for you if you
    81 distribute copies of the software, or if you modify it.
    82 
    83 </P>
    84 <P>
    85   For example, if you distribute copies of such a program, whether
    86 gratis or for a fee, you must give the recipients all the rights that
    87 you have.  You must make sure that they, too, receive or can get the
    88 source code.  And you must show them these terms so they know their
    89 rights.
    90 
    91 </P>
    92 <P>
    93   We protect your rights with two steps: (1) copyright the software, and
    94 (2) offer you this license which gives you legal permission to copy,
    95 distribute and/or modify the software.
    96 
    97 </P>
    98 <P>
    99   Also, for each author's protection and ours, we want to make certain
    100 that everyone understands that there is no warranty for this free
    101 software.  If the software is modified by someone else and passed on, we
    102 want its recipients to know that what they have is not the original, so
    103 that any problems introduced by others will not reflect on the original
    104 authors' reputations.
    105 
    106 </P>
    107 <P>
    108   Finally, any free program is threatened constantly by software
    109 patents.  We wish to avoid the danger that redistributors of a free
    110 program will individually obtain patent licenses, in effect making the
    111 program proprietary.  To prevent this, we have made it clear that any
    112 patent must be licensed for everyone's free use or not licensed at all.
    113 
    114 </P>
    115 <P>
    116   The precise terms and conditions for copying, distribution and
    117 modification follow.

    128  This License applies to any program or other work which contains
    129 a notice placed by the copyright holder saying it may be distributed
    130 under the terms of this General Public License.  The "Program", below,
    131 refers to any such program or work, and a "work based on the Program"
    132 means either the Program or any derivative work under copyright law:
    133 that is to say, a work containing the Program or a portion of it,
    134 either verbatim or with modifications and/or translated into another
    135 language.  (Hereinafter, translation is included without limitation in
    136 the term "modification".)  Each licensee is addressed as "you".
    137 <P>
    138 
    139 Activities other than copying, distribution and modification are not
    140 covered by this License; they are outside its scope.  The act of
    141 running the Program is not restricted, and the output from the Program
    142 is covered only if its contents constitute a work based on the
    143 Program (independent of having been made by running the Program).
    144 Whether that is true depends on what the Program does.
    145 
    146 <P>
    147 
    148 <STRONG>1.</STRONG>
    149  You may copy and distribute verbatim copies of the Program's
    150 source code as you receive it, in any medium, provided that you
    151 conspicuously and appropriately publish on each copy an appropriate
    152 copyright notice and disclaimer of warranty; keep intact all the
    153 notices that refer to this License and to the absence of any warranty;
    154 and give any other recipients of the Program a copy of this License
    155 along with the Program.
    156 <P>
    157 
    158 You may charge a fee for the physical act of transferring a copy, and
    159 you may at your option offer warranty protection in exchange for a fee.
    160 <P>
    161 
    162 <STRONG>2.</STRONG>
    163  You may modify your copy or copies of the Program or any portion
    164 of it, thus forming a work based on the Program, and copy and
    165 distribute such modifications or work under the terms of Section 1
    166 above, provided that you also meet all of these conditions:
    167 <P>
    168 
    169 <UL>
    170 
    171 <LI><STRONG>a)</STRONG>
    172      You must cause the modified files to carry prominent notices
    173      stating that you changed the files and the date of any change.
    174 
    175 <P>
    176 <LI><STRONG>b)</STRONG>
    177      You must cause any work that you distribute or publish, that in
    178      whole or in part contains or is derived from the Program or any
    179      part thereof, to be licensed as a whole at no charge to all third
    180      parties under the terms of this License.
    181 
    182 <P>
    183 <LI><STRONG>c)</STRONG>
    184      If the modified program normally reads commands interactively
    185      when run, you must cause it, when started running for such
    186      interactive use in the most ordinary way, to print or display an
    187      announcement including an appropriate copyright notice and a
    188      notice that there is no warranty (or else, saying that you provide
    189      a warranty) and that users may redistribute the program under
    190      these conditions, and telling the user how to view a copy of this
    191      License.  (Exception: if the Program itself is interactive but
    192      does not normally print such an announcement, your work based on
    193      the Program is not required to print an announcement.)
    194 </UL>
    195 
    196 These requirements apply to the modified work as a whole.  If
    197 identifiable sections of that work are not derived from the Program,
    198 and can be reasonably considered independent and separate works in
    199 themselves, then this License, and its terms, do not apply to those
    200 sections when you distribute them as separate works.  But when you
    201 distribute the same sections as part of a whole which is a work based
    202 on the Program, the distribution of the whole must be on the terms of
    203 this License, whose permissions for other licensees extend to the
    204 entire whole, and thus to each and every part regardless of who wrote it.
    205 <P>
    206 
    207 Thus, it is not the intent of this section to claim rights or contest
    208 your rights to work written entirely by you; rather, the intent is to
    209 exercise the right to control the distribution of derivative or
    210 collective works based on the Program.
    211 <P>
    212 
    213 In addition, mere aggregation of another work not based on the Program
    214 with the Program (or with a work based on the Program) on a volume of
    215 a storage or distribution medium does not bring the other work under
    216 the scope of this License.
    217 
    218 <P>
    219 
    220 <STRONG>3.</STRONG>
    221  You may copy and distribute the Program (or a work based on it,
    222 under Section 2) in object code or executable form under the terms of
    223 Sections 1 and 2 above provided that you also do one of the following:
    224 
    225 
    226 <!-- we use this doubled UL to get the sub-sections indented, -->
    227 <!-- while making the bullets as unobvious as possible. -->

    229 
    230 <LI><STRONG>a)</STRONG>
    231      Accompany it with the complete corresponding machine-readable
    232      source code, which must be distributed under the terms of Sections
    233      1 and 2 above on a medium customarily used for software interchange; or,
    234 
    235 <P>
    236 <LI><STRONG>b)</STRONG>
    237      Accompany it with a written offer, valid for at least three
    238      years, to give any third party, for a charge no more than your
    239      cost of physically performing source distribution, a complete
    240      machine-readable copy of the corresponding source code, to be
    241      distributed under the terms of Sections 1 and 2 above on a medium
    242      customarily used for software interchange; or,
    243 
    244 <P>
    245 <LI><STRONG>c)</STRONG>
    246      Accompany it with the information you received as to the offer
    247      to distribute corresponding source code.  (This alternative is
    248      allowed only for noncommercial distribution and only if you
    249      received the program in object code or executable form with such
    250      an offer, in accord with Subsection b above.)
    251 </UL>
    252 
    253 The source code for a work means the preferred form of the work for
    254 making modifications to it.  For an executable work, complete source
    255 code means all the source code for all modules it contains, plus any
    256 associated interface definition files, plus the scripts used to
    257 control compilation and installation of the executable.  However, as a
    258 special exception, the source code distributed need not include
    259 anything that is normally distributed (in either source or binary
    260 form) with the major components (compiler, kernel, and so on) of the
    261 operating system on which the executable runs, unless that component
    262 itself accompanies the executable.
    263 <P>
    264 
    265 If distribution of executable or object code is made by offering
    266 access to copy from a designated place, then offering equivalent
    267 access to copy the source code from the same place counts as
    268 distribution of the source code, even though third parties are not
    269 compelled to copy the source along with the object code.
    270 <P>
    271 
    272 <STRONG>4.</STRONG>
    273  You may not copy, modify, sublicense, or distribute the Program
    274 except as expressly provided under this License.  Any attempt
    275 otherwise to copy, modify, sublicense or distribute the Program is
    276 void, and will automatically terminate your rights under this License.
    277 However, parties who have received copies, or rights, from you under
    278 this License will not have their licenses terminated so long as such
    279 parties remain in full compliance.
    280 
    281 <P>
    282 
    283 <STRONG>5.</STRONG>
    284  You are not required to accept this License, since you have not
    285 signed it.  However, nothing else grants you permission to modify or
    286 distribute the Program or its derivative works.  These actions are
    287 prohibited by law if you do not accept this License.  Therefore, by
    288 modifying or distributing the Program (or any work based on the
    289 Program), you indicate your acceptance of this License to do so, and
    290 all its terms and conditions for copying, distributing or modifying
    291 the Program or works based on it.
    292 
    293 <P>
    294 
    295 <STRONG>6.</STRONG>
    296  Each time you redistribute the Program (or any work based on the
    297 Program), the recipient automatically receives a license from the
    298 original licensor to copy, distribute or modify the Program subject to
    299 these terms and conditions.  You may not impose any further
    300 restrictions on the recipients' exercise of the rights granted herein.
    301 You are not responsible for enforcing compliance by third parties to
    302 this License.
    303 
    304 <P>
    305 
    306 <STRONG>7.</STRONG>
    307  If, as a consequence of a court judgment or allegation of patent
    308 infringement or for any other reason (not limited to patent issues),
    309 conditions are imposed on you (whether by court order, agreement or
     48them if you wish), that you receive source code or can get it if you
     49want it, that you can change the software or use pieces of it in new
     50free programs, and that you know you can do these things.</p>
     51
     52<p>To protect your rights, we need to prevent others from denying you
     53these rights or asking you to surrender the rights.  Therefore, you have
     54certain responsibilities if you distribute copies of the software, or if
     55you modify it: responsibilities to respect the freedom of others.</p>
     56
     57<p>For example, if you distribute copies of such a program, whether
     58gratis or for a fee, you must pass on to the recipients the same
     59freedoms that you received.  You must make sure that they, too, receive
     60or can get the source code.  And you must show them these terms so they
     61know their rights.</p>
     62
     63<p>Developers that use the GNU GPL protect your rights with two steps:
     64(1) assert copyright on the software, and (2) offer you this License
     65giving you legal permission to copy, distribute and/or modify it.</p>
     66
     67<p>For the developers' and authors' protection, the GPL clearly explains
     68that there is no warranty for this free software.  For both users' and
     69authors' sake, the GPL requires that modified versions be marked as
     70changed, so that their problems will not be attributed erroneously to
     71authors of previous versions.</p>
     72
     73<p>Some devices are designed to deny users access to install or run
     74modified versions of the software inside them, although the manufacturer
     75can do so.  This is fundamentally incompatible with the aim of
     76protecting users' freedom to change the software.  The systematic
     77pattern of such abuse occurs in the area of products for individuals to
     78use, which is precisely where it is most unacceptable.  Therefore, we
     79have designed this version of the GPL to prohibit the practice for those
     80products.  If such problems arise substantially in other domains, we
     81stand ready to extend this provision to those domains in future versions
     82of the GPL, as needed to protect the freedom of users.</p>
     83
     84<p>Finally, every program is threatened constantly by software patents.
     85States should not allow patents to restrict development and use of
     86software on general-purpose computers, but in those that do, we wish to
     87avoid the special danger that patents applied to a free program could
     88make it effectively proprietary.  To prevent this, the GPL assures that
     89patents cannot be used to render the program non-free.</p>

     106
     107<p>To &ldquo;modify&rdquo; a work means to copy from or adapt all or part of the work
     108in a fashion requiring copyright permission, other than the making of an
     109exact copy.  The resulting work is called a &ldquo;modified version&rdquo; of the
     110earlier work or a work &ldquo;based on&rdquo; the earlier work.</p>
     111

     118computer or modifying a private copy.  Propagation includes copying,
     119distribution (with or without modification), making available to the
     120public, and in some countries other activities as well.</p>
     121
     122<p>To &ldquo;convey&rdquo; a work means any kind of propagation that enables other
     123parties to make or receive copies.  Mere interaction with a user through
     124a computer network, with no transfer of a copy, is not conveying.</p>
     125
     126<p>An interactive user interface displays &ldquo;Appropriate Legal Notices&rdquo;
     127to the extent that it includes a convenient and prominently visible
     128feature that (1) displays an appropriate copyright notice, and (2)
     129tells the user that there is no warranty for the work (except to the
     130extent that warranties are provided), that licensees may convey the
     131work under this License, and how to view a copy of this License.  If
     132the interface presents a list of user commands or options, such as a
     133menu, a prominent item in the list meets this criterion.</p>
     134
     135<h2><a name="section1"></a>1. Source Code.</h2>
     136
     137<p>The &ldquo;source code&rdquo; for a work means the preferred form of the work
     138for making modifications to it.  &ldquo;Object code&rdquo; means any non-source
     139form of a work.</p>
     140
     141<p>A &ldquo;Standard Interface&rdquo; means an interface that either is an official
     142standard defined by a recognized standards body, or, in the case of
     143interfaces specified for a particular programming language, one that
     144is widely used among developers working in that language.</p>
     145
     146<p>The &ldquo;System Libraries&rdquo; of an executable work include anything, other
     147than the work as a whole, that (a) is included in the normal form of
     148packaging a Major Component, but which is not part of that Major
     149Component, and (b) serves only to enable use of the work with that
     150Major Component, or to implement a Standard Interface for which an
     151implementation is available to the public in source code form.  A
     152&ldquo;Major Component&rdquo;, in this context, means a major essential component
     153(kernel, window system, and so on) of the specific operating system
     154(if any) on which the executable work runs, or a compiler used to
     155produce the work, or an object code interpreter used to run it.</p>
     156
     157<p>The &ldquo;Corresponding Source&rdquo; for a work in object code form means all
     158the source code needed to generate, install, and (for an executable
     159work) run the object code and to modify the work, including scripts to
     160control those activities.  However, it does not include the work's
     161System Libraries, or general-purpose tools or generally available free
     162programs which are used unmodified in performing those activities but
     163which are not part of the work.  For example, Corresponding Source
     164includes interface definition files associated with source files for
     165the work, and the source code for shared libraries and dynamically
     166linked subprograms that the work is specifically designed to require,
     167such as by intimate data communication or control flow between those
     168subprograms and other parts of the work.</p>
     169
     170<p>The Corresponding Source need not include anything that users
     171can regenerate automatically from other parts of the Corresponding
     172Source.</p>
     173
     174<p>The Corresponding Source for a work in source code form is that
     175same work.</p>
     176
     177<h2><a name="section2"></a>2. Basic Permissions.</h2>
     178
     179<p>All rights granted under this License are granted for the term of
     180copyright on the Program, and are irrevocable provided the stated
     181conditions are met.  This License explicitly affirms your unlimited
     182permission to run the unmodified Program.  The output from running a
     183covered work is covered by this License only if the output, given its
     184content, constitutes a covered work.  This License acknowledges your
     185rights of fair use or other equivalent, as provided by copyright law.</p>
     186
     187<p>You may make, run and propagate covered works that you do not
     188convey, without conditions so long as your license otherwise remains
     189in force.  You may convey covered works to others for the sole purpose
     190of having them make modifications exclusively for you, or provide you
     191with facilities for running those works, provided that you comply with
     192the terms of this License in conveying all material for which you do
     193not control copyright.  Those thus making or running the covered works
     194for you must do so exclusively on your behalf, under your direction
     195and control, on terms that prohibit them from making any copies of
     196your copyrighted material outside their relationship with you.</p>
     197
     198<p>Conveying under any other circumstances is permitted solely under
     199the conditions stated below.  Sublicensing is not allowed; section 10
     200makes it unnecessary.</p>
     201
     202<h2><a name="section3"></a>3. Protecting Users' Legal Rights From Anti-Circumvention Law.</h2>
     203
     204<p>No covered work shall be deemed part of an effective technological
     205measure under any applicable law fulfilling obligations under article
     20611 of the WIPO copyright treaty adopted on 20 December 1996, or
     207similar laws prohibiting or restricting circumvention of such
     208measures.</p>
     209
     210<p>When you convey a covered work, you waive any legal power to forbid
     211circumvention of technological measures to the extent such circumvention
     212is effected by exercising rights under this License with respect to
     213the covered work, and you disclaim any intention to limit operation or
     214modification of the work as a means of enforcing, against the work's
     215users, your or third parties' legal rights to forbid circumvention of
     216technological measures.</p>
     217
     218<h2><a name="section4"></a>4. Conveying Verbatim Copies.</h2>
     219
     220<p>You may convey verbatim copies of the Program's source code as you
     221receive it, in any medium, provided that you conspicuously and
     222appropriately publish on each copy an appropriate copyright notice;
     223keep intact all notices stating that this License and any
     224non-permissive terms added in accord with section 7 apply to the code;
     225keep intact all notices of the absence of any warranty; and give all
     226recipients a copy of this License along with the Program.</p>
     227
     228<p>You may charge any price or no price for each copy that you convey,
     229and you may offer support or warranty protection for a fee.</p>
     230
     231<h2><a name="section5"></a>5. Conveying Modified Source Versions.</h2>
     232
     233<p>You may convey a work based on the Program, or the modifications to
     234produce it from the Program, in the form of source code under the
     235terms of section 4, provided that you also meet all of these conditions:</p>
     236
     237<ul>
     238<li>a) The work must carry prominent notices stating that you modified
     239    it, and giving a relevant date.</li>
     240
     241<li>b) The work must carry prominent notices stating that it is
     242    released under this License and any conditions added under section
     243    7.  This requirement modifies the requirement in section 4 to
     244    &ldquo;keep intact all notices&rdquo;.</li>
     245
     246<li>c) You must license the entire work, as a whole, under this
     247    License to anyone who comes into possession of a copy.  This
     248    License will therefore apply, along with any applicable section 7
     249    additional terms, to the whole of the work, and all its parts,
     250    regardless of how they are packaged.  This License gives no
     251    permission to license the work in any other way, but it does not
     252    invalidate such permission if you have separately received it.</li>
     253
     254<li>d) If the work has interactive user interfaces, each must display
     255    Appropriate Legal Notices; however, if the Program has interactive
     256    interfaces that do not display Appropriate Legal Notices, your
     257    work need not make them do so.</li>
     258</ul>
     259
     260<p>A compilation of a covered work with other separate and independent
     261works, which are not by their nature extensions of the covered work,
     262and which are not combined with it such as to form a larger program,
     263in or on a volume of a storage or distribution medium, is called an
     264&ldquo;aggregate&rdquo; if the compilation and its resulting copyright are not
     265used to limit the access or legal rights of the compilation's users
     266beyond what the individual works permit.  Inclusion of a covered work
     267in an aggregate does not cause this License to apply to the other
     268parts of the aggregate.</p>
     269
     270<h2><a name="section6"></a>6. Conveying Non-Source Forms.</h2>
     271
     272<p>You may convey a covered work in object code form under the terms
     273of sections 4 and 5, provided that you also convey the
     274machine-readable Corresponding Source under the terms of this License,
     275in one of these ways:</p>
     276
     277<ul>
     278<li>a) Convey the object code in, or embodied in, a physical product
     279    (including a physical distribution medium), accompanied by the
     280    Corresponding Source fixed on a durable physical medium
     281    customarily used for software interchange.</li>
     282
     283<li>b) Convey the object code in, or embodied in, a physical product
     284    (including a physical distribution medium), accompanied by a
     285    written offer, valid for at least three years and valid for as
     286    long as you offer spare parts or customer support for that product
     287    model, to give anyone who possesses the object code either (1) a
     288    copy of the Corresponding Source for all the software in the
     289    product that is covered by this License, on a durable physical
     290    medium customarily used for software interchange, for a price no
     291    more than your reasonable cost of physically performing this
     292    conveying of source, or (2) access to copy the
     293    Corresponding Source from a network server at no charge.</li>
     294
     295<li>c) Convey individual copies of the object code with a copy of the
     296    written offer to provide the Corresponding Source.  This
     297    alternative is allowed only occasionally and noncommercially, and
     298    only if you received the object code with such an offer, in accord
     299    with subsection 6b.</li>
     300
     301<li>d) Convey the object code by offering access from a designated
     302    place (gratis or for a charge), and offer equivalent access to the
     303    Corresponding Source in the same way through the same place at no
     304    further charge.  You need not require recipients to copy the
     305    Corresponding Source along with the object code.  If the place to
     306    copy the object code is a network server, the Corresponding Source
     307    may be on a different server (operated by you or a third party)
     308    that supports equivalent copying facilities, provided you maintain
     309    clear directions next to the object code saying where to find the
     310    Corresponding Source.  Regardless of what server hosts the
     311    Corresponding Source, you remain obligated to ensure that it is
     312    available for as long as needed to satisfy these requirements.</li>
     313
     314<li>e) Convey the object code using peer-to-peer transmission, provided
     315    you inform other peers where the object code and Corresponding
     316    Source of the work are being offered to the general public at no
     317    charge under subsection 6d.</li>
     318</ul>
     319
     320<p>A separable portion of the object code, whose source code is excluded
     321from the Corresponding Source as a System Library, need not be
     322included in conveying the object code work.</p>
     323
     324<p>A &ldquo;User Product&rdquo; is either (1) a &ldquo;consumer product&rdquo;, which means any
     325tangible personal property which is normally used for personal, family,
     326or household purposes, or (2) anything designed or sold for incorporation
     327into a dwelling.  In determining whether a product is a consumer product,
     328doubtful cases shall be resolved in favor of coverage.  For a particular
     329product received by a particular user, &ldquo;normally used&rdquo; refers to a
     330typical or common use of that class of product, regardless of the status
     331of the particular user or of the way in which the particular user
     332actually uses, or expects or is expected to use, the product.  A product
     333is a consumer product regardless of whether the product has substantial
     334commercial, industrial or non-consumer uses, unless such uses represent
     335the only significant mode of use of the product.</p>
     336
     337<p>&ldquo;Installation Information&rdquo; for a User Product means any methods,
     338procedures, authorization keys, or other information required to install
     339and execute modified versions of a covered work in that User Product from
     340a modified version of its Corresponding Source.  The information must
     341suffice to ensure that the continued functioning of the modified object
     342code is in no case prevented or interfered with solely because
     343modification has been made.</p>
     344
     345<p>If you convey an object code work under this section in, or with, or
     346specifically for use in, a User Product, and the conveying occurs as
     347part of a transaction in which the right of possession and use of the
     348User Product is transferred to the recipient in perpetuity or for a
     349fixed term (regardless of how the transaction is characterized), the
     350Corresponding Source conveyed under this section must be accompanied
     351by the Installation Information.  But this requirement does not apply
     352if neither you nor any third party retains the ability to install
     353modified object code on the User Product (for example, the work has
     354been installed in ROM).</p>
     355
     356<p>The requirement to provide Installation Information does not include a
     357requirement to continue to provide support service, warranty, or updates
     358for a work that has been modified or installed by the recipient, or for
     359the User Product in which it has been modified or installed.  Access to a
     360network may be denied when the modification itself materially and
     361adversely affects the operation of the network or violates the rules and
     362protocols for communication across the network.</p>
     363
     364<p>Corresponding Source conveyed, and Installation Information provided,
     365in accord with this section must be in a format that is publicly
     366documented (and with an implementation available to the public in
     367source code form), and must require no special password or key for
     368unpacking, reading or copying.</p>
     369
     370<h2><a name="section7"></a>7. Additional Terms.</h2>
     371
     372<p>&ldquo;Additional permissions&rdquo; are terms that supplement the terms of this
     373License by making exceptions from one or more of its conditions.
     374Additional permissions that are applicable to the entire Program shall
     375be treated as though they were included in this License, to the extent
     376that they are valid under applicable law.  If additional permissions
     377apply only to part of the Program, that part may be used separately
     378under those permissions, but the entire Program remains governed by
     379this License without regard to the additional permissions.</p>
     380
     381<p>When you convey a copy of a covered work, you may at your option
     382remove any additional permissions from that copy, or from any part of
     383it.  (Additional permissions may be written to require their own
     384removal in certain cases when you modify the work.)  You may place
     385additional permissions on material, added by you to a covered work,
     386for which you have or can give appropriate copyright permission.</p>
     387
     388<p>Notwithstanding any other provision of this License, for material you
     389add to a covered work, you may (if authorized by the copyright holders of
     390that material) supplement the terms of this License with terms:</p>
     391
     392<ul>
     393<li>a) Disclaiming warranty or limiting liability differently from the
     394    terms of sections 15 and 16 of this License; or</li>
     395
     396<li>b) Requiring preservation of specified reasonable legal notices or
     397    author attributions in that material or in the Appropriate Legal
     398    Notices displayed by works containing it; or</li>
     399
     400<li>c) Prohibiting misrepresentation of the origin of that material, or
     401    requiring that modified versions of such material be marked in
     402    reasonable ways as different from the original version; or</li>
     403
     404<li>d) Limiting the use for publicity purposes of names of licensors or
     405    authors of the material; or</li>
     406
     407<li>e) Declining to grant rights under trademark law for use of some
     408    trade names, trademarks, or service marks; or</li>
     409
     410<li>f) Requiring indemnification of licensors and authors of that
     411    material by anyone who conveys the material (or modified versions of
     412    it) with contractual assumptions of liability to the recipient, for
     413    any liability that these contractual assumptions directly impose on
     414    those licensors and authors.</li>
     415</ul>
     416
     417<p>All other non-permissive additional terms are considered &ldquo;further
     418restrictions&rdquo; within the meaning of section 10.  If the Program as you
     419received it, or any part of it, contains a notice stating that it is
     420governed by this License along with a term that is a further
     421restriction, you may remove that term.  If a license document contains
     422a further restriction but permits relicensing or conveying under this
     423License, you may add to a covered work material governed by the terms
     424of that license document, provided that the further restriction does
     425not survive such relicensing or conveying.</p>
     426
     427<p>If you add terms to a covered work in accord with this section, you
     428must place, in the relevant source files, a statement of the
     429additional terms that apply to those files, or a notice indicating
     430where to find the applicable terms.</p>
     431
     432<p>Additional terms, permissive or non-permissive, may be stated in the
     433form of a separately written license, or stated as exceptions;
     434the above requirements apply either way.</p>
     435
     436<h2><a name="section8"></a>8. Termination.</h2>
     437
     438<p>You may not propagate or modify a covered work except as expressly
     439provided under this License.  Any attempt otherwise to propagate or
     440modify it is void, and will automatically terminate your rights under
     441this License (including any patent licenses granted under the third
     442paragraph of section 11).</p>
     443
     444<p>However, if you cease all violation of this License, then your
     445license from a particular copyright holder is reinstated (a)
     446provisionally, unless and until the copyright holder explicitly and
     447finally terminates your license, and (b) permanently, if the copyright
     448holder fails to notify you of the violation by some reasonable means
     449prior to 60 days after the cessation.</p>
     450
     451<p>Moreover, your license from a particular copyright holder is
     452reinstated permanently if the copyright holder notifies you of the
     453violation by some reasonable means, this is the first time you have
     454received notice of violation of this License (for any work) from that
     455copyright holder, and you cure the violation prior to 30 days after
     456your receipt of the notice.</p>
     457
     458<p>Termination of your rights under this section does not terminate the
     459licenses of parties who have received copies or rights from you under
     460this License.  If your rights have been terminated and not permanently
     461reinstated, you do not qualify to receive new licenses for the same
     462material under section 10.</p>
     463
     464<h2><a name="section9"></a>9. Acceptance Not Required for Having Copies.</h2>
     465
     466<p>You are not required to accept this License in order to receive or
     467run a copy of the Program.  Ancillary propagation of a covered work
     468occurring solely as a consequence of using peer-to-peer transmission
     469to receive a copy likewise does not require acceptance.  However,
     470nothing other than this License grants you permission to propagate or
     471modify any covered work.  These actions infringe copyright if you do
     472not accept this License.  Therefore, by modifying or propagating a
     473covered work, you indicate your acceptance of this License to do so.</p>
     474
     475<h2><a name="section10"></a>10. Automatic Licensing of Downstream Recipients.</h2>
     476
     477<p>Each time you convey a covered work, the recipient automatically
     478receives a license from the original licensors, to run, modify and
     479propagate that work, subject to this License.  You are not responsible
     480for enforcing compliance by third parties with this License.</p>
     481
     482<p>An &ldquo;entity transaction&rdquo; is a transaction transferring control of an
     483organization, or substantially all assets of one, or subdividing an
     484organization, or merging organizations.  If propagation of a covered
     485work results from an entity transaction, each party to that
     486transaction who receives a copy of the work also receives whatever
     487licenses to the work the party's predecessor in interest had or could
     488give under the previous paragraph, plus a right to possession of the
     489Corresponding Source of the work from the predecessor in interest, if
     490the predecessor has it or can get it with reasonable efforts.</p>
     491
     492<p>You may not impose any further restrictions on the exercise of the
     493rights granted or affirmed under this License.  For example, you may
     494not impose a license fee, royalty, or other charge for exercise of
     495rights granted under this License, and you may not initiate litigation
     496(including a cross-claim or counterclaim in a lawsuit) alleging that
     497any patent claim is infringed by making, using, selling, offering for
     498sale, or importing the Program or any portion of it.</p>
     499
     500<h2><a name="section11"></a>11. Patents.</h2>
     501
     502<p>A &ldquo;contributor&rdquo; is a copyright holder who authorizes use under this
     503License of the Program or a work on which the Program is based.  The
     504work thus licensed is called the contributor's &ldquo;contributor version&rdquo;.</p>
     505
     506<p>A contributor's &ldquo;essential patent claims&rdquo; are all patent claims
     507owned or controlled by the contributor, whether already acquired or
     508hereafter acquired, that would be infringed by some manner, permitted
     509by this License, of making, using, or selling its contributor version,
     510but do not include claims that would be infringed only as a
     511consequence of further modification of the contributor version.  For
     512purposes of this definition, &ldquo;control&rdquo; includes the right to grant
     513patent sublicenses in a manner consistent with the requirements of
     514this License.</p>
     515
     516<p>Each contributor grants you a non-exclusive, worldwide, royalty-free
     517patent license under the contributor's essential patent claims, to
     518make, use, sell, offer for sale, import and otherwise run, modify and

     521<p>In the following three paragraphs, a &ldquo;patent license&rdquo; is any express
     522agreement or commitment, however denominated, not to enforce a patent
     523(such as an express permission to practice a patent or covenant not to
     524sue for patent infringement).  To &ldquo;grant&rdquo; such a patent license to a
     525party means to make such an agreement or commitment not to enforce a
     526patent against the party.</p>
     527
     528<p>If you convey a covered work, knowingly relying on a patent license,
     529and the Corresponding Source of the work is not available for anyone
     530to copy, free of charge and under the terms of this License, through a
     531publicly available network server or other readily accessible means,
     532then you must either (1) cause the Corresponding Source to be so
     533available, or (2) arrange to deprive yourself of the benefit of the
     534patent license for this particular work, or (3) arrange, in a manner
     535consistent with the requirements of this License, to extend the patent
     536license to downstream recipients.  &ldquo;Knowingly relying&rdquo; means you have
     537actual knowledge that, but for the patent license, your conveying the
     538covered work in a country, or your recipient's use of the covered work
     539in a country, would infringe one or more identifiable patents in that
     540country that you have reason to believe are valid.</p>
     541 
     542<p>If, pursuant to or in connection with a single transaction or
     543arrangement, you convey, or propagate by procuring conveyance of, a
     544covered work, and grant a patent license to some of the parties
     545receiving the covered work authorizing them to use, propagate, modify
     546or convey a specific copy of the covered work, then the patent license
     547you grant is automatically extended to all recipients of the covered
     548work and works based on it.</p>
     549
     550<p>A patent license is &ldquo;discriminatory&rdquo; if it does not include within
     551the scope of its coverage, prohibits the exercise of, or is
     552conditioned on the non-exercise of one or more of the rights that are
     553specifically granted under this License.  You may not convey a covered
     554work if you are a party to an arrangement with a third party that is
     555in the business of distributing software, under which you make payment
     556to the third party based on the extent of your activity of conveying
     557the work, and under which the third party grants, to any of the
     558parties who would receive the covered work from you, a discriminatory
     559patent license (a) in connection with copies of the covered work
     560conveyed by you (or copies made from those copies), or (b) primarily
     561for and in connection with specific products or compilations that
     562contain the covered work, unless you entered into that arrangement,
     563or that patent license was granted, prior to 28 March 2007.</p>
     564
     565<p>Nothing in this License shall be construed as excluding or limiting
     566any implied license or other defenses to infringement that may
     567otherwise be available to you under applicable patent law.</p>
     568
     569<h2><a name="section12"></a>12. No Surrender of Others' Freedom.</h2>
     570
     571<p>If conditions are imposed on you (whether by court order, agreement or
    310572otherwise) that contradict the conditions of this License, they do not
    311 excuse you from the conditions of this License.  If you cannot
    312 distribute so as to satisfy simultaneously your obligations under this
    313 License and any other pertinent obligations, then as a consequence you
    314 may not distribute the Program at all.  For example, if a patent
    315 license would not permit royalty-free redistribution of the Program by
    316 all those who receive copies directly or indirectly through you, then
    317 the only way you could satisfy both it and this License would be to
    318 refrain entirely from distribution of the Program.
    319 <P>
    320 
    321 If any portion of this section is held invalid or unenforceable under
    322 any particular circumstance, the balance of the section is intended to
    323 apply and the section as a whole is intended to apply in other
    324 circumstances.
    325 <P>
    326 
    327 It is not the purpose of this section to induce you to infringe any
    328 patents or other property right claims or to contest validity of any
    329 such claims; this section has the sole purpose of protecting the
    330 integrity of the free software distribution system, which is
    331 implemented by public license practices.  Many people have made
    332 generous contributions to the wide range of software distributed
    333 through that system in reliance on consistent application of that
    334 system; it is up to the author/donor to decide if he or she is willing
    335 to distribute software through any other system and a licensee cannot
    336 impose that choice.
    337 <P>
    338 
    339 This section is intended to make thoroughly clear what is believed to
    340 be a consequence of the rest of this License.

    345  If the distribution and/or use of the Program is restricted in
    346 certain countries either by patents or by copyrighted interfaces, the
    347 original copyright holder who places the Program under this License
    348 may add an explicit geographical distribution limitation excluding
    349 those countries, so that distribution is permitted only in or among
    350 countries not thus excluded.  In such case, this License incorporates
    351 the limitation as if written in the body of this License.

    356  The Free Software Foundation may publish revised and/or new versions
    357 of the General Public License from time to time.  Such new versions will
     573excuse you from the conditions of this License.  If you cannot convey a
     574covered work so as to satisfy simultaneously your obligations under this
     575License and any other pertinent obligations, then as a consequence you may
     576not convey it at all.  For example, if you agree to terms that obligate you
     577to collect a royalty for further conveying from those to whom you convey
     578the Program, the only way you could satisfy both those terms and this
     579License would be to refrain entirely from conveying the Program.</p>

     583<p>Notwithstanding any other provision of this License, you have
     584permission to link or combine any covered work with a work licensed
     585under version 3 of the GNU Affero General Public License into a single
     586combined work, and to convey the resulting work.  The terms of this
     587License will continue to apply to the part which is the covered work,
     588but the special requirements of the GNU Affero General Public License,
     589section 13, concerning interaction through a network will apply to the

    359 address new problems or concerns.
    360 <P>
    361 
    362 Each version is given a distinguishing version number.  If the Program
    363 specifies a version number of this License which applies to it and "any
    364 later version", you have the option of following the terms and conditions
    365 either of that version or of any later version published by the Free
    366 Software Foundation.  If the Program does not specify a version number of
