 |

 | 
| 
 | 
     4  Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
 | 
| 
 | 
     5  Everyone is permitted to copy and distribute verbatim copies
 | 
| 
 | 
     6  of this license document, but changing it is not allowed.
 | 
| 
 | 
     7 
 | 
| 
 | 
     8                             Preamble
 | 
| 
 | 
     9 
 | 
| 
 | 
    10   The GNU General Public License is a free, copyleft license for
 | 
| 
 | 
    11 software and other kinds of works.
 | 
| 
 | 
    12 
 | 
| 
 | 
    13   The licenses for most software and other practical works are designed
 | 
| 
 | 
    14 to take away your freedom to share and change the works.  By contrast,
 | 
| 
 | 
    15 the GNU General Public License is intended to guarantee your freedom to
 | 
| 
 | 
    16 share and change all versions of a program--to make sure it remains free
 | 
| 
 | 
    17 software for all its users.  We, the Free Software Foundation, use the
 | 
| 
 | 
    18 GNU General Public License for most of our software; it applies also to
 | 
| 
 | 
    19 any other work released this way by its authors.  You can apply it to
 | 
| 
 | 
    20 your programs, too.
 | 
| 
 | 
    21 
 | 
| 
 | 
    22   When we speak of free software, we are referring to freedom, not
 | 
| 
 | 
    23 price.  Our General Public Licenses are designed to make sure that you
 | 
| 
 | 
    24 have the freedom to distribute copies of free software (and charge for
 | 
| 
 | 
    25 them if you wish), that you receive source code or can get it if you
 | 
| 
 | 
    26 want it, that you can change the software or use pieces of it in new
 | 
| 
 | 
    27 free programs, and that you know you can do these things.
 | 
| 
 | 
    28 
 | 
| 
 | 
    29   To protect your rights, we need to prevent others from denying you
 | 
| 
 | 
    30 these rights or asking you to surrender the rights.  Therefore, you have
 | 
| 
 | 
    31 certain responsibilities if you distribute copies of the software, or if
 | 
| 
 | 
    32 you modify it: responsibilities to respect the freedom of others.
 | 
| 
 | 
    33 
 | 
| 
 | 
    34   For example, if you distribute copies of such a program, whether
 | 
| 
 | 
    35 gratis or for a fee, you must pass on to the recipients the same
 | 
| 
 | 
    36 freedoms that you received.  You must make sure that they, too, receive
 | 
| 
 | 
    37 or can get the source code.  And you must show them these terms so they
 | 
| 
 | 
    38 know their rights.
 | 
| 
 | 
    39 
 | 
| 
 | 
    40   Developers that use the GNU GPL protect your rights with two steps:
 | 
| 
 | 
    41 (1) assert copyright on the software, and (2) offer you this License
 | 
| 
 | 
    42 giving you legal permission to copy, distribute and/or modify it.
 | 
| 
 | 
    43 
 | 
| 
 | 
    44   For the developers' and authors' protection, the GPL clearly explains
 | 
| 
 | 
    45 that there is no warranty for this free software.  For both users' and
 | 
| 
 | 
    46 authors' sake, the GPL requires that modified versions be marked as
 | 
| 
 | 
    47 changed, so that their problems will not be attributed erroneously to
 | 
| 
 | 
    48 authors of previous versions.
 | 
| 
 | 
    49 
 | 
| 
 | 
    50   Some devices are designed to deny users access to install or run
 | 
| 
 | 
    51 modified versions of the software inside them, although the manufacturer
 | 
| 
 | 
    52 can do so.  This is fundamentally incompatible with the aim of
 | 
| 
 | 
    53 protecting users' freedom to change the software.  The systematic
 | 
| 
 | 
    54 pattern of such abuse occurs in the area of products for individuals to
 | 
| 
 | 
    55 use, which is precisely where it is most unacceptable.  Therefore, we
 | 
| 
 | 
    56 have designed this version of the GPL to prohibit the practice for those
 | 
| 
 | 
    57 products.  If such problems arise substantially in other domains, we
 | 
| 
 | 
    58 stand ready to extend this provision to those domains in future versions
 | 
| 
 | 
    59 of the GPL, as needed to protect the freedom of users.
 | 
| 
 | 
    60 
 | 
| 
 | 
    61   Finally, every program is threatened constantly by software patents.
 | 
| 
 | 
    62 States should not allow patents to restrict development and use of
 | 
| 
 | 
    63 software on general-purpose computers, but in those that do, we wish to
 | 
| 
 | 
    64 avoid the special danger that patents applied to a free program could
 | 
| 
 | 
    65 make it effectively proprietary.  To prevent this, the GPL assures that
 | 
| 
 | 
    66 patents cannot be used to render the program non-free.
 | 
| 
 | 
    67 
 | 
| 
 | 
    68   The precise terms and conditions for copying, distribution and
 | 
| 
 | 
    69 modification follow.
 | 
| 
 | 
    70 
 | 
| 
 | 
    71                        TERMS AND CONDITIONS
 | 
| 
 | 
    72 
 | 
| 
 | 
    73   0. Definitions.
 | 
| 
 | 
    74 
 | 
| 
 | 
    75   "This License" refers to version 3 of the GNU General Public License.
 | 
| 
 | 
    76 
 | 
| 
 | 
    77   "Copyright" also means copyright-like laws that apply to other kinds of
 | 
| 
 | 
    78 works, such as semiconductor masks.
 | 
| 
 | 
    79 
 | 
| 
 | 
    80   "The Program" refers to any copyrightable work licensed under this
 | 
| 
 | 
    81 License.  Each licensee is addressed as "you".  "Licensees" and
 | 
| 
 | 
    82 "recipients" may be individuals or organizations.
 | 
| 
 | 
    83 
 | 
| 
 | 
    84   To "modify" a work means to copy from or adapt all or part of the work
 | 
| 
 | 
    85 in a fashion requiring copyright permission, other than the making of an
 | 
| 
 | 
    86 exact copy.  The resulting work is called a "modified version" of the
 | 
| 
 | 
    87 earlier work or a work "based on" the earlier work.
 | 
| 
 | 
    88 
 | 
| 
 | 
    89   A "covered work" means either the unmodified Program or a work based
 | 
| 
 | 
    90 on the Program.
 | 
| 
 | 
    91 
 | 
| 
 | 
    92   To "propagate" a work means to do anything with it that, without
 | 
| 
 | 
    93 permission, would make you directly or secondarily liable for
 | 
| 
 | 
    94 infringement under applicable copyright law, except executing it on a
 | 
| 
 | 
    95 computer or modifying a private copy.  Propagation includes copying,
 | 
| 
 | 
    96 distribution (with or without modification), making available to the
 | 
| 
 | 
    97 public, and in some countries other activities as well.
 | 
| 
 | 
    98 
 | 
| 
 | 
    99   To "convey" a work means any kind of propagation that enables other
 | 
| 
 | 
   100 parties to make or receive copies.  Mere interaction with a user through
 | 
| 
 | 
   101 a computer network, with no transfer of a copy, is not conveying.
 | 
| 
 | 
   102 
 | 
| 
 | 
   103   An interactive user interface displays "Appropriate Legal Notices"
 | 
| 
 | 
   104 to the extent that it includes a convenient and prominently visible
 | 
| 
 | 
   105 feature that (1) displays an appropriate copyright notice, and (2)
 | 
| 
 | 
   106 tells the user that there is no warranty for the work (except to the
 | 
| 
 | 
   107 extent that warranties are provided), that licensees may convey the
 | 
| 
 | 
   108 work under this License, and how to view a copy of this License.  If
 | 
| 
 | 
   109 the interface presents a list of user commands or options, such as a
 | 
| 
 | 
   110 menu, a prominent item in the list meets this criterion.
 | 
| 
 | 
   111 
 | 
| 
 | 
   112   1. Source Code.
 | 
| 
 | 
   113 
 | 
| 
 | 
   114   The "source code" for a work means the preferred form of the work
 | 
| 
 | 
   115 for making modifications to it.  "Object code" means any non-source
 | 
| 
 | 
   116 form of a work.
 | 
| 
 | 
   117 
 | 
| 
 | 
   118   A "Standard Interface" means an interface that either is an official
 | 
| 
 | 
   119 standard defined by a recognized standards body, or, in the case of
 | 
| 
 | 
   120 interfaces specified for a particular programming language, one that
 | 
| 
 | 
   121 is widely used among developers working in that language.
 | 
| 
 | 
   122 
 | 
| 
 | 
   123   The "System Libraries" of an executable work include anything, other
 | 
| 
 | 
   124 than the work as a whole, that (a) is included in the normal form of
 | 
| 
 | 
   125 packaging a Major Component, but which is not part of that Major
 | 
| 
 | 
   126 Component, and (b) serves only to enable use of the work with that
 | 
| 
 | 
   127 Major Component, or to implement a Standard Interface for which an
 | 
| 
 | 
   128 implementation is available to the public in source code form.  A
 | 
| 
 | 
   129 "Major Component", in this context, means a major essential component
 | 
| 
 | 
   130 (kernel, window system, and so on) of the specific operating system
 | 
| 
 | 
   131 (if any) on which the executable work runs, or a compiler used to
 | 
| 
 | 
   132 produce the work, or an object code interpreter used to run it.
 | 
| 
 | 
   133 
 | 
| 
 | 
   134   The "Corresponding Source" for a work in object code form means all
 | 
| 
 | 
   135 the source code needed to generate, install, and (for an executable
 | 
| 
 | 
   136 work) run the object code and to modify the work, including scripts to
 | 
| 
 | 
   137 control those activities.  However, it does not include the work's
 | 
| 
 | 
   138 System Libraries, or general-purpose tools or generally available free
 | 
| 
 | 
   139 programs which are used unmodified in performing those activities but
 | 
| 
 | 
   140 which are not part of the work.  For example, Corresponding Source
 | 
| 
 | 
   141 includes interface definition files associated with source files for
 | 
| 
 | 
   142 the work, and the source code for shared libraries and dynamically
 | 
| 
 | 
   143 linked subprograms that the work is specifically designed to require,
 | 
| 
 | 
   144 such as by intimate data communication or control flow between those
 | 
| 
 | 
   145 subprograms and other parts of the work.
 | 
| 
 | 
   146 
 | 
| 
 | 
   147   The Corresponding Source need not include anything that users
 | 
| 
 | 
   148 can regenerate automatically from other parts of the Corresponding
 | 
| 
 | 
   149 Source.
 | 
| 
 | 
   150 
 | 
| 
 | 
   151   The Corresponding Source for a work in source code form is that
 | 
| 
 | 
   152 same work.
 | 
| 
 | 
   153 
 | 
| 
 | 
   154   2. Basic Permissions.
 | 
| 
 | 
   155 
 | 
| 
 | 
   156   All rights granted under this License are granted for the term of
 | 
| 
 | 
   157 copyright on the Program, and are irrevocable provided the stated
 | 
| 
 | 
   158 conditions are met.  This License explicitly affirms your unlimited
 | 
| 
 | 
   159 permission to run the unmodified Program.  The output from running a
 | 
| 
 | 
   160 covered work is covered by this License only if the output, given its
 | 
| 
 | 
   161 content, constitutes a covered work.  This License acknowledges your
 | 
| 
 | 
   162 rights of fair use or other equivalent, as provided by copyright law.
 | 
| 
 | 
   163 
 | 
| 
 | 
   164   You may make, run and propagate covered works that you do not
 | 
| 
 | 
   165 convey, without conditions so long as your license otherwise remains
 | 
| 
 | 
   166 in force.  You may convey covered works to others for the sole purpose
 | 
| 
 | 
   167 of having them make modifications exclusively for you, or provide you
 | 
| 
 | 
   168 with facilities for running those works, provided that you comply with
 | 
| 
 | 
   169 the terms of this License in conveying all material for which you do
 | 
| 
 | 
   170 not control copyright.  Those thus making or running the covered works
 | 
| 
 | 
   171 for you must do so exclusively on your behalf, under your direction
 | 
| 
 | 
   172 and control, on terms that prohibit them from making any copies of
 | 
| 
 | 
   173 your copyrighted material outside their relationship with you.
 | 
| 
 | 
   174 
 | 
| 
 | 
   175   Conveying under any other circumstances is permitted solely under
 | 
| 
 | 
   176 the conditions stated below.  Sublicensing is not allowed; section 10
 | 
| 
 | 
   177 makes it unnecessary.
 | 
| 
 | 
   178 
 | 
| 
 | 
   179   3. Protecting Users' Legal Rights From Anti-Circumvention Law.
 | 
| 
 | 
   180 
 | 
| 
 | 
   181   No covered work shall be deemed part of an effective technological
 | 
| 
 | 
   182 measure under any applicable law fulfilling obligations under article
 | 
| 
 | 
   183 11 of the WIPO copyright treaty adopted on 20 December 1996, or
 | 
| 
 | 
   184 similar laws prohibiting or restricting circumvention of such
 | 
| 
 | 
   185 measures.
 | 
| 
 | 
   186 
 | 
| 
 | 
   187   When you convey a covered work, you waive any legal power to forbid
 | 
| 
 | 
   188 circumvention of technological measures to the extent such circumvention
 | 
| 
 | 
   189 is effected by exercising rights under this License with respect to
 | 
| 
 | 
   190 the covered work, and you disclaim any intention to limit operation or
 | 
| 
 | 
   191 modification of the work as a means of enforcing, against the work's
 | 
| 
 | 
   192 users, your or third parties' legal rights to forbid circumvention of
 | 
| 
 | 
   193 technological measures.
 | 
| 
 | 
   194 
 | 
| 
 | 
   195   4. Conveying Verbatim Copies.
 | 
| 
 | 
   196 
 | 
| 
 | 
   197   You may convey verbatim copies of the Program's source code as you
 | 
| 
 | 
   198 receive it, in any medium, provided that you conspicuously and
 | 
| 
 | 
   199 appropriately publish on each copy an appropriate copyright notice;
 | 
| 
 | 
   200 keep intact all notices stating that this License and any
 | 
| 
 | 
   201 non-permissive terms added in accord with section 7 apply to the code;
 | 
| 
 | 
   202 keep intact all notices of the absence of any warranty; and give all
 | 
| 
 | 
   203 recipients a copy of this License along with the Program.
 | 
| 
 | 
   204 
 | 
| 
 | 
   205   You may charge any price or no price for each copy that you convey,
 | 
| 
 | 
   206 and you may offer support or warranty protection for a fee.
 | 
| 
 | 
   207 
 | 
| 
 | 
   208   5. Conveying Modified Source Versions.
 | 
| 
 | 
   209 
 | 
| 
 | 
   210   You may convey a work based on the Program, or the modifications to
 | 
| 
 | 
   211 produce it from the Program, in the form of source code under the
 | 
| 
 | 
   212 terms of section 4, provided that you also meet all of these conditions:
 | 
| 
 | 
   213 
 | 
| 
 | 
   214     a) The work must carry prominent notices stating that you modified
 | 
| 
 | 
   215     it, and giving a relevant date.
 | 
| 
 | 
   216 
 | 
| 
 | 
   217     b) The work must carry prominent notices stating that it is
 | 
| 
 | 
   218     released under this License and any conditions added under section
 | 
| 
 | 
   219     7.  This requirement modifies the requirement in section 4 to
 | 
| 
 | 
   220     "keep intact all notices".
 | 
| 
 | 
   221 
 | 
| 
 | 
   222     c) You must license the entire work, as a whole, under this
 | 
| 
 | 
   223     License to anyone who comes into possession of a copy.  This
 | 
| 
 | 
   224     License will therefore apply, along with any applicable section 7
 | 
| 
 | 
   225     additional terms, to the whole of the work, and all its parts,
 | 
| 
 | 
   226     regardless of how they are packaged.  This License gives no
 | 
| 
 | 
   227     permission to license the work in any other way, but it does not
 | 
| 
 | 
   228     invalidate such permission if you have separately received it.
 | 
| 
 | 
   229 
 | 
| 
 | 
   230     d) If the work has interactive user interfaces, each must display
 | 
| 
 | 
   231     Appropriate Legal Notices; however, if the Program has interactive
 | 
| 
 | 
   232     interfaces that do not display Appropriate Legal Notices, your
 | 
| 
 | 
   233     work need not make them do so.
 | 
| 
 | 
   234 
 | 
| 
 | 
   235   A compilation of a covered work with other separate and independent
 | 
| 
 | 
   236 works, which are not by their nature extensions of the covered work,
 | 
| 
 | 
   237 and which are not combined with it such as to form a larger program,
 | 
| 
 | 
   238 in or on a volume of a storage or distribution medium, is called an
 | 
| 
 | 
   239 "aggregate" if the compilation and its resulting copyright are not
 | 
| 
 | 
   240 used to limit the access or legal rights of the compilation's users
 | 
| 
 | 
   241 beyond what the individual works permit.  Inclusion of a covered work
 | 
| 
 | 
   242 in an aggregate does not cause this License to apply to the other
 | 
| 
 | 
   243 parts of the aggregate.
 | 
| 
 | 
   244 
 | 
| 
 | 
   245   6. Conveying Non-Source Forms.
 | 
| 
 | 
   246 
 | 
| 
 | 
   247   You may convey a covered work in object code form under the terms
 | 
| 
 | 
   248 of sections 4 and 5, provided that you also convey the
 | 
| 
 | 
   249 machine-readable Corresponding Source under the terms of this License,
 | 
| 
 | 
   250 in one of these ways:
 | 
| 
 | 
   251 
 | 
| 
 | 
   252     a) Convey the object code in, or embodied in, a physical product
 | 
| 
 | 
   253     (including a physical distribution medium), accompanied by the
 | 
| 
 | 
   254     Corresponding Source fixed on a durable physical medium
 | 
| 
 | 
   255     customarily used for software interchange.
 | 
| 
 | 
   256 
 | 
| 
 | 
   257     b) Convey the object code in, or embodied in, a physical product
 | 
| 
 | 
   258     (including a physical distribution medium), accompanied by a
 | 
| 
 | 
   259     written offer, valid for at least three years and valid for as
 | 
| 
 | 
   260     long as you offer spare parts or customer support for that product
 | 
| 
 | 
   261     model, to give anyone who possesses the object code either (1) a
 | 
| 
 | 
   262     copy of the Corresponding Source for all the software in the
 | 
| 
 | 
   263     product that is covered by this License, on a durable physical
 | 
| 
 | 
   264     medium customarily used for software interchange, for a price no
 | 
| 
 | 
   265     more than your reasonable cost of physically performing this
 | 
| 
 | 
   266     conveying of source, or (2) access to copy the
 | 
| 
 | 
   267     Corresponding Source from a network server at no charge.
 | 
| 
 | 
   268 
 | 
| 
 | 
   269     c) Convey individual copies of the object code with a copy of the
 | 
| 
 | 
   270     written offer to provide the Corresponding Source.  This
 | 
| 
 | 
   271     alternative is allowed only occasionally and noncommercially, and
 | 
| 
 | 
   272     only if you received the object code with such an offer, in accord
 | 
| 
 | 
   273     with subsection 6b.
 | 
| 
 | 
   274 
 | 
| 
 | 
   275     d) Convey the object code by offering access from a designated
 | 
| 
 | 
   276     place (gratis or for a charge), and offer equivalent access to the
 | 
| 
 | 
   277     Corresponding Source in the same way through the same place at no
 | 
| 
 | 
   278     further charge.  You need not require recipients to copy the
 | 
| 
 | 
   279     Corresponding Source along with the object code.  If the place to
 | 
| 
 | 
   280     copy the object code is a network server, the Corresponding Source
 | 
| 
 | 
   281     may be on a different server (operated by you or a third party)
 | 
| 
 | 
   282     that supports equivalent copying facilities, provided you maintain
 | 
| 
 | 
   283     clear directions next to the object code saying where to find the
 | 
| 
 | 
   284     Corresponding Source.  Regardless of what server hosts the
 | 
| 
 | 
   285     Corresponding Source, you remain obligated to ensure that it is
 | 
| 
 | 
   286     available for as long as needed to satisfy these requirements.
 | 
| 
 | 
   287 
 | 
| 
 | 
   288     e) Convey the object code using peer-to-peer transmission, provided
 | 
| 
 | 
   289     you inform other peers where the object code and Corresponding
 | 
| 
 | 
   290     Source of the work are being offered to the general public at no
 | 
| 
 | 
   291     charge under subsection 6d.
 | 
| 
 | 
   292 
 | 
| 
 | 
   293   A separable portion of the object code, whose source code is excluded
 | 
| 
 | 
   294 from the Corresponding Source as a System Library, need not be
 | 
| 
 | 
   295 included in conveying the object code work.
 | 
| 
 | 
   296 
 | 
| 
 | 
   297   A "User Product" is either (1) a "consumer product", which means any
 | 
| 
 | 
   298 tangible personal property which is normally used for personal, family,
 | 
| 
 | 
   299 or household purposes, or (2) anything designed or sold for incorporation
 | 
| 
 | 
   300 into a dwelling.  In determining whether a product is a consumer product,
 | 
| 
 | 
   301 doubtful cases shall be resolved in favor of coverage.  For a particular
 | 
| 
 | 
   302 product received by a particular user, "normally used" refers to a
 | 
| 
 | 
   303 typical or common use of that class of product, regardless of the status
 | 
| 
 | 
   304 of the particular user or of the way in which the particular user
 | 
| 
 | 
   305 actually uses, or expects or is expected to use, the product.  A product
 | 
| 
 | 
   306 is a consumer product regardless of whether the product has substantial
 | 
| 
 | 
   307 commercial, industrial or non-consumer uses, unless such uses represent
 | 
| 
 | 
   308 the only significant mode of use of the product.
 | 
| 
 | 
   309 
 | 
| 
 | 
   310   "Installation Information" for a User Product means any methods,
 | 
| 
 | 
   311 procedures, authorization keys, or other information required to install
 | 
| 
 | 
   312 and execute modified versions of a covered work in that User Product from
 | 
| 
 | 
   313 a modified version of its Corresponding Source.  The information must
 | 
| 
 | 
   314 suffice to ensure that the continued functioning of the modified object
 | 
| 
 | 
   315 code is in no case prevented or interfered with solely because
 | 
| 
 | 
   316 modification has been made.
 | 
| 
 | 
   317 
 | 
| 
 | 
   318   If you convey an object code work under this section in, or with, or
 | 
| 
 | 
   319 specifically for use in, a User Product, and the conveying occurs as
 | 
| 
 | 
   320 part of a transaction in which the right of possession and use of the
 | 
| 
 | 
   321 User Product is transferred to the recipient in perpetuity or for a
 | 
| 
 | 
   322 fixed term (regardless of how the transaction is characterized), the
 | 
| 
 | 
   323 Corresponding Source conveyed under this section must be accompanied
 | 
| 
 | 
   324 by the Installation Information.  But this requirement does not apply
 | 
| 
 | 
   325 if neither you nor any third party retains the ability to install
 | 
| 
 | 
   326 modified object code on the User Product (for example, the work has
 | 
| 
 | 
   327 been installed in ROM).
 | 
| 
 | 
   328 
 | 
| 
 | 
   329   The requirement to provide Installation Information does not include a
 | 
| 
 | 
   330 requirement to continue to provide support service, warranty, or updates
 | 
| 
 | 
   331 for a work that has been modified or installed by the recipient, or for
 | 
| 
 | 
   332 the User Product in which it has been modified or installed.  Access to a
 | 
| 
 | 
   333 network may be denied when the modification itself materially and
 | 
| 
 | 
   334 adversely affects the operation of the network or violates the rules and
 | 
| 
 | 
   335 protocols for communication across the network.
 | 
| 
 | 
   336 
 | 
| 
 | 
   337   Corresponding Source conveyed, and Installation Information provided,
 | 
| 
 | 
   338 in accord with this section must be in a format that is publicly
 | 
| 
 | 
   339 documented (and with an implementation available to the public in
 | 
| 
 | 
   340 source code form), and must require no special password or key for
 | 
| 
 | 
   341 unpacking, reading or copying.
 | 
| 
 | 
   342 
 | 
| 
 | 
   343   7. Additional Terms.
 | 
| 
 | 
   344 
 | 
| 
 | 
   345   "Additional permissions" are terms that supplement the terms of this
 | 
| 
 | 
   346 License by making exceptions from one or more of its conditions.
 | 
| 
 | 
   347 Additional permissions that are applicable to the entire Program shall
 | 
| 
 | 
   348 be treated as though they were included in this License, to the extent
 | 
| 
 | 
   349 that they are valid under applicable law.  If additional permissions
 | 
| 
 | 
   350 apply only to part of the Program, that part may be used separately
 | 
| 
 | 
   351 under those permissions, but the entire Program remains governed by
 | 
| 
 | 
   352 this License without regard to the additional permissions.
 | 
| 
 | 
   353 
 | 
| 
 | 
   354   When you convey a copy of a covered work, you may at your option
 | 
| 
 | 
   355 remove any additional permissions from that copy, or from any part of
 | 
| 
 | 
   356 it.  (Additional permissions may be written to require their own
 | 
| 
 | 
   357 removal in certain cases when you modify the work.)  You may place
 | 
| 
 | 
   358 additional permissions on material, added by you to a covered work,
 | 
| 
 | 
   359 for which you have or can give appropriate copyright permission.
 | 
| 
 | 
   360 
 | 
| 
 | 
   361   Notwithstanding any other provision of this License, for material you
 | 
| 
 | 
   362 add to a covered work, you may (if authorized by the copyright holders of
 | 
| 
 | 
   363 that material) supplement the terms of this License with terms:
 | 
| 
 | 
   364 
 | 
| 
 | 
   365     a) Disclaiming warranty or limiting liability differently from the
 | 
| 
 | 
   366     terms of sections 15 and 16 of this License; or
 | 
| 
 | 
   367 
 | 
| 
 | 
   368     b) Requiring preservation of specified reasonable legal notices or
 | 
| 
 | 
   369     author attributions in that material or in the Appropriate Legal
 | 
| 
 | 
   370     Notices displayed by works containing it; or
 | 
| 
 | 
   371 
 | 
| 
 | 
   372     c) Prohibiting misrepresentation of the origin of that material, or
 | 
| 
 | 
   373     requiring that modified versions of such material be marked in
 | 
| 
 | 
   374     reasonable ways as different from the original version; or
 | 
| 
 | 
   375 
 | 
| 
 | 
   376     d) Limiting the use for publicity purposes of names of licensors or
 | 
| 
 | 
   377     authors of the material; or
 | 
| 
 | 
   378 
 | 
| 
 | 
   379     e) Declining to grant rights under trademark law for use of some
 | 
| 
 | 
   380     trade names, trademarks, or service marks; or
 | 
| 
 | 
   381 
 | 
| 
 | 
   382     f) Requiring indemnification of licensors and authors of that
 | 
| 
 | 
   383     material by anyone who conveys the material (or modified versions of
 | 
| 
 | 
   384     it) with contractual assumptions of liability to the recipient, for
 | 
| 
 | 
   385     any liability that these contractual assumptions directly impose on
 | 
| 
 | 
   386     those licensors and authors.
 | 
| 
 | 
   387 
 | 
| 
 | 
   388   All other non-permissive additional terms are considered "further
 | 
| 
 | 
   389 restrictions" within the meaning of section 10.  If the Program as you
 | 
| 
 | 
   390 received it, or any part of it, contains a notice stating that it is
 | 
| 
 | 
   391 governed by this License along with a term that is a further
 | 
| 
 | 
   392 restriction, you may remove that term.  If a license document contains
 | 
| 
 | 
   393 a further restriction but permits relicensing or conveying under this
 | 
| 
 | 
   394 License, you may add to a covered work material governed by the terms
 | 
| 
 | 
   395 of that license document, provided that the further restriction does
 | 
| 
 | 
   396 not survive such relicensing or conveying.
 | 
| 
 | 
   397 
 | 
| 
 | 
   398   If you add terms to a covered work in accord with this section, you
 | 
| 
 | 
   399 must place, in the relevant source files, a statement of the
 | 
| 
 | 
   400 additional terms that apply to those files, or a notice indicating
 | 
| 
 | 
   401 where to find the applicable terms.
 | 
| 
 | 
   402 
 | 
| 
 | 
   403   Additional terms, permissive or non-permissive, may be stated in the
 | 
| 
 | 
   404 form of a separately written license, or stated as exceptions;
 | 
| 
 | 
   405 the above requirements apply either way.
 | 
| 
 | 
   406 
 | 
| 
 | 
   407   8. Termination.
 | 
| 
 | 
   408 
 | 
| 
 | 
   409   You may not propagate or modify a covered work except as expressly
 | 
| 
 | 
   410 provided under this License.  Any attempt otherwise to propagate or
 | 
| 
 | 
   411 modify it is void, and will automatically terminate your rights under
 | 
| 
 | 
   412 this License (including any patent licenses granted under the third
 | 
| 
 | 
   413 paragraph of section 11).
 | 
| 
 | 
   414 
 | 
| 
 | 
   415   However, if you cease all violation of this License, then your
 | 
| 
 | 
   416 license from a particular copyright holder is reinstated (a)
 | 
| 
 | 
   417 provisionally, unless and until the copyright holder explicitly and
 | 
| 
 | 
   418 finally terminates your license, and (b) permanently, if the copyright
 | 
| 
 | 
   419 holder fails to notify you of the violation by some reasonable means
 | 
| 
 | 
   420 prior to 60 days after the cessation.
 | 
| 
 | 
   421 
 | 
| 
 | 
   422   Moreover, your license from a particular copyright holder is
 | 
| 
 | 
   423 reinstated permanently if the copyright holder notifies you of the
 | 
| 
 | 
   424 violation by some reasonable means, this is the first time you have
 | 
| 
 | 
   425 received notice of violation of this License (for any work) from that
 | 
| 
 | 
   426 copyright holder, and you cure the violation prior to 30 days after
 | 
| 
 | 
   427 your receipt of the notice.
 | 
| 
 | 
   428 
 | 
| 
 | 
   429   Termination of your rights under this section does not terminate the
 | 
| 
 | 
   430 licenses of parties who have received copies or rights from you under
 | 
| 
 | 
   431 this License.  If your rights have been terminated and not permanently
 | 
| 
 | 
   432 reinstated, you do not qualify to receive new licenses for the same
 | 
| 
 | 
   433 material under section 10.
 | 
| 
 | 
   434 
 | 
| 
 | 
   435   9. Acceptance Not Required for Having Copies.
 | 
| 
 | 
   436 
 | 
| 
 | 
   437   You are not required to accept this License in order to receive or
 | 
| 
 | 
   438 run a copy of the Program.  Ancillary propagation of a covered work
 | 
| 
 | 
   439 occurring solely as a consequence of using peer-to-peer transmission
 | 
| 
 | 
   440 to receive a copy likewise does not require acceptance.  However,
 | 
| 
 | 
   441 nothing other than this License grants you permission to propagate or
 | 
| 
 | 
   442 modify any covered work.  These actions infringe copyright if you do
 | 
| 
 | 
   443 not accept this License.  Therefore, by modifying or propagating a
 | 
| 
 | 
   444 covered work, you indicate your acceptance of this License to do so.
 | 
| 
 | 
   445 
 | 
| 
 | 
   446   10. Automatic Licensing of Downstream Recipients.
 | 
| 
 | 
   447 
 | 
| 
 | 
   448   Each time you convey a covered work, the recipient automatically
 | 
| 
 | 
   449 receives a license from the original licensors, to run, modify and
 | 
| 
 | 
   450 propagate that work, subject to this License.  You are not responsible
 | 
| 
 | 
   451 for enforcing compliance by third parties with this License.
 | 
| 
 | 
   452 
 | 
| 
 | 
   453   An "entity transaction" is a transaction transferring control of an
 | 
| 
 | 
   454 organization, or substantially all assets of one, or subdividing an
 | 
| 
 | 
   455 organization, or merging organizations.  If propagation of a covered
 | 
| 
 | 
   456 work results from an entity transaction, each party to that
 | 
| 
 | 
   457 transaction who receives a copy of the work also receives whatever
 | 
| 
 | 
   458 licenses to the work the party's predecessor in interest had or could
 | 
| 
 | 
   459 give under the previous paragraph, plus a right to possession of the
 | 
| 
 | 
   460 Corresponding Source of the work from the predecessor in interest, if
 | 
| 
 | 
   461 the predecessor has it or can get it with reasonable efforts.
 | 
| 
 | 
   462 
 | 
| 
 | 
   463   You may not impose any further restrictions on the exercise of the
 | 
| 
 | 
   464 rights granted or affirmed under this License.  For example, you may
 | 
| 
 | 
   465 not impose a license fee, royalty, or other charge for exercise of
 | 
| 
 | 
   466 rights granted under this License, and you may not initiate litigation
 | 
| 
 | 
   467 (including a cross-claim or counterclaim in a lawsuit) alleging that
 | 
| 
 | 
   468 any patent claim is infringed by making, using, selling, offering for
 | 
| 
 | 
   469 sale, or importing the Program or any portion of it.
 | 
| 
 | 
   470 
 | 
| 
 | 
   471   11. Patents.
 | 
| 
 | 
   472 
 | 
| 
 | 
   473   A "contributor" is a copyright holder who authorizes use under this
 | 
| 
 | 
   474 License of the Program or a work on which the Program is based.  The
 | 
| 
 | 
   475 work thus licensed is called the contributor's "contributor version".
 | 
| 
 | 
   476 
 | 
| 
 | 
   477   A contributor's "essential patent claims" are all patent claims
 | 
| 
 | 
   478 owned or controlled by the contributor, whether already acquired or
 | 
| 
 | 
   479 hereafter acquired, that would be infringed by some manner, permitted
 | 
| 
 | 
   480 by this License, of making, using, or selling its contributor version,
 | 
| 
 | 
   481 but do not include claims that would be infringed only as a
 | 
| 
 | 
   482 consequence of further modification of the contributor version.  For
 | 
| 
 | 
   483 purposes of this definition, "control" includes the right to grant
 | 
| 
 | 
   484 patent sublicenses in a manner consistent with the requirements of
 | 
| 
 | 
   485 this License.
 | 
| 
 | 
   486 
 | 
| 
 | 
   487   Each contributor grants you a non-exclusive, worldwide, royalty-free
 | 
| 
 | 
   488 patent license under the contributor's essential patent claims, to
 | 
| 
 | 
   489 make, use, sell, offer for sale, import and otherwise run, modify and
 | 
| 
 | 
   490 propagate the contents of its contributor version.
 | 
| 
 | 
   491 
 | 
| 
 | 
   492   In the following three paragraphs, a "patent license" is any express
 | 
| 
 | 
   493 agreement or commitment, however denominated, not to enforce a patent
 | 
| 
 | 
   494 (such as an express permission to practice a patent or covenant not to
 | 
| 
 | 
   495 sue for patent infringement).  To "grant" such a patent license to a
 | 
| 
 | 
   496 party means to make such an agreement or commitment not to enforce a
 | 
| 
 | 
   497 patent against the party.
 | 
| 
 | 
   498 
 | 
| 
 | 
   499   If you convey a covered work, knowingly relying on a patent license,
 | 
| 
 | 
   500 and the Corresponding Source of the work is not available for anyone
 | 
| 
 | 
   501 to copy, free of charge and under the terms of this License, through a
 | 
| 
 | 
   502 publicly available network server or other readily accessible means,
 | 
| 
 | 
   503 then you must either (1) cause the Corresponding Source to be so
 | 
| 
 | 
   504 available, or (2) arrange to deprive yourself of the benefit of the
 | 
| 
 | 
   505 patent license for this particular work, or (3) arrange, in a manner
 | 
| 
 | 
   506 consistent with the requirements of this License, to extend the patent
 | 
| 
 | 
   507 license to downstream recipients.  "Knowingly relying" means you have
 | 
| 
 | 
   508 actual knowledge that, but for the patent license, your conveying the
 | 
| 
 | 
   509 covered work in a country, or your recipient's use of the covered work
 | 
| 
 | 
   510 in a country, would infringe one or more identifiable patents in that
 | 
| 
 | 
   511 country that you have reason to believe are valid.
 | 
| 
 | 
   512 
 | 
| 
 | 
   513   If, pursuant to or in connection with a single transaction or
 | 
| 
 | 
   514 arrangement, you convey, or propagate by procuring conveyance of, a
 | 
| 
 | 
   515 covered work, and grant a patent license to some of the parties
 | 
| 
 | 
   516 receiving the covered work authorizing them to use, propagate, modify
 | 
| 
 | 
   517 or convey a specific copy of the covered work, then the patent license
 | 
| 
 | 
   518 you grant is automatically extended to all recipients of the covered
 | 
| 
 | 
   519 work and works based on it.
 | 
| 
 | 
   520 
 | 
| 
 | 
   521   A patent license is "discriminatory" if it does not include within
 | 
| 
 | 
   522 the scope of its coverage, prohibits the exercise of, or is
 | 
| 
 | 
   523 conditioned on the non-exercise of one or more of the rights that are
 | 
| 
 | 
   524 specifically granted under this License.  You may not convey a covered
 | 
| 
 | 
   525 work if you are a party to an arrangement with a third party that is
 | 
| 
 | 
   526 in the business of distributing software, under which you make payment
 | 
| 
 | 
   527 to the third party based on the extent of your activity of conveying
 | 
| 
 | 
   528 the work, and under which the third party grants, to any of the
 | 
| 
 | 
   529 parties who would receive the covered work from you, a discriminatory
 | 
| 
 | 
   530 patent license (a) in connection with copies of the covered work
 | 
| 
 | 
   531 conveyed by you (or copies made from those copies), or (b) primarily
 | 
| 
 | 
   532 for and in connection with specific products or compilations that
 | 
| 
 | 
   533 contain the covered work, unless you entered into that arrangement,
 | 
| 
 | 
   534 or that patent license was granted, prior to 28 March 2007.
 | 
| 
 | 
   535 
 | 
| 
 | 
   536   Nothing in this License shall be construed as excluding or limiting
 | 
| 
 | 
   537 any implied license or other defenses to infringement that may
 | 
| 
 | 
   538 otherwise be available to you under applicable patent law.
 | 
| 
 | 
   539 
 | 
| 
 | 
   540   12. No Surrender of Others' Freedom.
 | 
| 
 | 
   541 
 | 
| 
 | 
   542   If conditions are imposed on you (whether by court order, agreement or
 | 
| 
 | 
   543 otherwise) that contradict the conditions of this License, they do not
 | 
| 
 | 
   544 excuse you from the conditions of this License.  If you cannot convey a
 | 
| 
 | 
   545 covered work so as to satisfy simultaneously your obligations under this
 | 
| 
 | 
   546 License and any other pertinent obligations, then as a consequence you may
 | 
| 
 | 
   547 not convey it at all.  For example, if you agree to terms that obligate you
 | 
| 
 | 
   548 to collect a royalty for further conveying from those to whom you convey
 | 
| 
 | 
   549 the Program, the only way you could satisfy both those terms and this
 | 
| 
 | 
   550 License would be to refrain entirely from conveying the Program.
 | 
| 
 | 
   551 
 | 
| 
 | 
   552   13. Use with the GNU Affero General Public License.
 | 
| 
 | 
   553 
 | 
| 
 | 
   554   Notwithstanding any other provision of this License, you have
 | 
| 
 | 
   555 permission to link or combine any covered work with a work licensed
 | 
| 
 | 
   556 under version 3 of the GNU Affero General Public License into a single
 | 
| 
 | 
   557 combined work, and to convey the resulting work.  The terms of this
 | 
| 
 | 
   558 License will continue to apply to the part which is the covered work,
 | 
| 
 | 
   559 but the special requirements of the GNU Affero General Public License,
 | 
| 
 | 
   560 section 13, concerning interaction through a network will apply to the
 | 
| 
 | 
   561 combination as such.
 | 
| 
 | 
   562 
 | 
| 
 | 
   563   14. Revised Versions of this License.
 | 
| 
 | 
   564 
 | 
| 
 | 
   565   The Free Software Foundation may publish revised and/or new versions of
 | 
| 
 | 
   566 the GNU General Public License from time to time.  Such new versions will
 | 
| 
 | 
   567 be similar in spirit to the present version, but may differ in detail to
 | 
| 
 | 
   568 address new problems or concerns.
 | 
| 
 | 
   569 
 | 
| 
 | 
   570   Each version is given a distinguishing version number.  If the
 | 
| 
 | 
   571 Program specifies that a certain numbered version of the GNU General
 | 
| 
 | 
   572 Public License "or any later version" applies to it, you have the
 | 
| 
 | 
   573 option of following the terms and conditions either of that numbered
 | 
| 
 | 
   574 version or of any later version published by the Free Software
 | 
| 
 | 
   575 Foundation.  If the Program does not specify a version number of the
 | 
| 
 | 
   576 GNU General Public License, you may choose any version ever published
 | 
| 
 | 
   577 by the Free Software Foundation.
 | 
| 
 | 
   578 
 | 
| 
 | 
   579   If the Program specifies that a proxy can decide which future
 | 
| 
 | 
   580 versions of the GNU General Public License can be used, that proxy's
 | 
| 
 | 
   581 public statement of acceptance of a version permanently authorizes you
 | 
| 
 | 
   582 to choose that version for the Program.
 | 
| 
 | 
   583 
 | 
| 
 | 
   584   Later license versions may give you additional or different
 | 
| 
 | 
   585 permissions.  However, no additional obligations are imposed on any
 | 
| 
 | 
   586 author or copyright holder as a result of your choosing to follow a
 | 
| 
 | 
   587 later version.
 | 
| 
 | 
   588 
 | 
| 
 | 
   589   15. Disclaimer of Warranty.
 | 
| 
 | 
   590 
 | 
| 
 | 
   591   THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
 | 
| 
 | 
   592 APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
 | 
| 
 | 
   593 HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
 | 
| 
 | 
   594 OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
 | 
| 
 | 
   595 THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
 | 
| 
 | 
   596 PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
 | 
| 
 | 
   597 IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
 | 
| 
 | 
   598 ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
 | 
| 
 | 
   599 
 | 
| 
 | 
   600   16. Limitation of Liability.
 | 
| 
 | 
   601 
 | 
| 
 | 
   602   IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
 | 
| 
 | 
   603 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
 | 
| 
 | 
   604 THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
 | 
| 
 | 
   605 GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
 | 
| 
 | 
   606 USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
 | 
| 
 | 
   607 DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
 | 
| 
 | 
   608 PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
 | 
| 
 | 
   609 EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
 | 
| 
 | 
   610 SUCH DAMAGES.
 | 
| 
 | 
   611 
 | 
| 
 | 
   612   17. Interpretation of Sections 15 and 16.
 | 
| 
 | 
   613 
 | 
| 
 | 
   614   If the disclaimer of warranty and limitation of liability provided
 | 
| 
 | 
   615 above cannot be given local legal effect according to their terms,
 | 
| 
 | 
   616 reviewing courts shall apply local law that most closely approximates
 | 
| 
 | 
   617 an absolute waiver of all civil liability in connection with the
 | 
| 
 | 
   618 Program, unless a warranty or assumption of liability accompanies a
 | 
| 
 | 
   619 copy of the Program in return for a fee.
