  13                     GNU LESSER GENERAL PUBLIC LICENSE
  14                         Version 3, 29 June 2007
  15  
  16   Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
  17   Everyone is permitted to copy and distribute verbatim copies
  18   of this license document, but changing it is not allowed.
  19  
  20  
  21    This version of the GNU Lesser General Public License incorporates
  22  the terms and conditions of version 3 of the GNU General Public
  23  License, supplemented by the additional permissions listed below.
  24  
  25    0. Additional Definitions.
  26  
  27    As used herein, "this License" refers to version 3 of the GNU Lesser
  28  General Public License, and the "GNU GPL" refers to version 3 of the GNU
  29  General Public License.
  30  
  31    "The Library" refers to a covered work governed by this License,
  32  other than an Application or a Combined Work as defined below.
  33  
  34    An "Application" is any work that makes use of an interface provided
  35  by the Library, but which is not otherwise based on the Library.
  36  Defining a subclass of a class defined by the Library is deemed a mode
  37  of using an interface provided by the Library.
  38  
  39    A "Combined Work" is a work produced by combining or linking an
  40  Application with the Library.  The particular version of the Library
  41  with which the Combined Work was made is also called the "Linked
  42  Version".
  43  
  44    The "Minimal Corresponding Source" for a Combined Work means the
  45  Corresponding Source for the Combined Work, excluding any source code
  46  for portions of the Combined Work that, considered in isolation, are
  47  based on the Application, and not on the Linked Version.
  48  
  49    The "Corresponding Application Code" for a Combined Work means the
  50  object code and/or source code for the Application, including any data
  51  and utility programs needed for reproducing the Combined Work from the
  52  Application, but excluding the System Libraries of the Combined Work.
  53  
  54    1. Exception to Section 3 of the GNU GPL.
  55  
  56    You may convey a covered work under sections 3 and 4 of this License
  57  without being bound by section 3 of the GNU GPL.
  58  
  59    2. Conveying Modified Versions.
  60  
  61    If you modify a copy of the Library, and, in your modifications, a
  62  facility refers to a function or data to be supplied by an Application
  63  that uses the facility (other than as an argument passed when the
  64  facility is invoked), then you may convey a copy of the modified
  65  version:
  66  
  67     a) under this License, provided that you make a good faith effort to
  68     ensure that, in the event an Application does not supply the
  69     function or data, the facility still operates, and performs
  70     whatever part of its purpose remains meaningful, or
  71  
  72     b) under the GNU GPL, with none of the additional permissions of
  73     this License applicable to that copy.
  74  
  75    3. Object Code Incorporating Material from Library Header Files.
  76  
  77    The object code form of an Application may incorporate material from
  78  a header file that is part of the Library.  You may convey such object
  79  code under terms of your choice, provided that, if the incorporated
  80  material is not limited to numerical parameters, data structure
  81  layouts and accessors, or small macros, inline functions and templates
  82  (ten or fewer lines in length), you do both of the following:
  83  
  84     a) Give prominent notice with each copy of the object code that the
  85     Library is used in it and that the Library and its use are
  86     covered by this License.
  87  
  88     b) Accompany the object code with a copy of the GNU GPL and this license
  89     document.
  90  
  91    4. Combined Works.
  92  
  93    You may convey a Combined Work under terms of your choice that,
  94  taken together, effectively do not restrict modification of the
  95  portions of the Library contained in the Combined Work and reverse
  96  engineering for debugging such modifications, if you also do each of
  97  the following:
  98  
  99     a) Give prominent notice with each copy of the Combined Work that
 100     the Library is used in it and that the Library and its use are
 101     covered by this License.
 102  
 103     b) Accompany the Combined Work with a copy of the GNU GPL and this license
 104     document.
 105  
 106     c) For a Combined Work that displays copyright notices during
 107     execution, include the copyright notice for the Library among
 108     these notices, as well as a reference directing the user to the
 109     copies of the GNU GPL and this license document.
 110  
 111     d) Do one of the following:
 112  
 113         0) Convey the Minimal Corresponding Source under the terms of this
 114         License, and the Corresponding Application Code in a form
 115         suitable for, and under terms that permit, the user to
 116         recombine or relink the Application with a modified version of
 117         the Linked Version to produce a modified Combined Work, in the
 118         manner specified by section 6 of the GNU GPL for conveying
 119         Corresponding Source.
 120  
 121         1) Use a suitable shared library mechanism for linking with the
 122         Library.  A suitable mechanism is one that (a) uses at run time
 123         a copy of the Library already present on the user's computer
 124         system, and (b) will operate properly with a modified version
 125         of the Library that is interface-compatible with the Linked
 126         Version.
 127  
 128     e) Provide Installation Information, but only if you would otherwise
 129     be required to provide such information under section 6 of the
 130     GNU GPL, and only to the extent that such information is
 131     necessary to install and execute a modified version of the
 132     Combined Work produced by recombining or relinking the
 133     Application with a modified version of the Linked Version. (If
 134     you use option 4d0, the Installation Information must accompany
 135     the Minimal Corresponding Source and Corresponding Application
 136     Code. If you use option 4d1, you must provide the Installation
 137     Information in the manner specified by section 6 of the GNU GPL
 138     for conveying Corresponding Source.)
 139  
 140    5. Combined Libraries.
 141  
 142    You may place library facilities that are a work based on the
 143  Library side by side in a single library together with other library
 144  facilities that are not Applications and are not covered by this
 145  License, and convey such a combined library under terms of your
 146  choice, if you do both of the following:
 147  
 148     a) Accompany the combined library with a copy of the same work based
 149     on the Library, uncombined with any other library facilities,
 150     conveyed under the terms of this License.
 151  
 152     b) Give prominent notice with the combined library that part of it
 153     is a work based on the Library, and explaining where to find the
 154     accompanying uncombined form of the same work.
 155  
 156    6. Revised Versions of the GNU Lesser General Public License.
 157  
 158    The Free Software Foundation may publish revised and/or new versions
 159  of the GNU Lesser General Public License from time to time. Such new
 160  versions will be similar in spirit to the present version, but may
 161  differ in detail to address new problems or concerns.
 162  
 163    Each version is given a distinguishing version number. If the
 164  Library as you received it specifies that a certain numbered version
 165  of the GNU Lesser General Public License "or any later version"
 166  applies to it, you have the option of following the terms and
 167  conditions either of that published version or of any later version
 168  published by the Free Software Foundation. If the Library as you
 169  received it does not specify a version number of the GNU Lesser
 170  General Public License, you may choose any version of the GNU Lesser
 171  General Public License ever published by the Free Software Foundation.
 172  
 173    If the Library as you received it specifies that a proxy can decide
 174  whether future versions of the GNU Lesser General Public License shall
 175  apply, that proxy's public statement of acceptance of any version is
 176  permanent authorization for you to choose that version for the
 177  Library.

 182                      GNU GENERAL PUBLIC LICENSE
 183                         Version 3, 29 June 2007
 184  
 185   Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
 186   Everyone is permitted to copy and distribute verbatim copies
 187   of this license document, but changing it is not allowed.
 188  
 189                              Preamble
 190  
 191    The GNU General Public License is a free, copyleft license for
 192  software and other kinds of works.
 193  
 194    The licenses for most software and other practical works are designed
 195  to take away your freedom to share and change the works.  By contrast,
 196  the GNU General Public License is intended to guarantee your freedom to
 197  share and change all versions of a program--to make sure it remains free
 198  software for all its users.  We, the Free Software Foundation, use the
 199  GNU General Public License for most of our software; it applies also to
 200  any other work released this way by its authors.  You can apply it to
 201  your programs, too.
 202  
 203    When we speak of free software, we are referring to freedom, not
 204  price.  Our General Public Licenses are designed to make sure that you
 205  have the freedom to distribute copies of free software (and charge for
 206  them if you wish), that you receive source code or can get it if you
 207  want it, that you can change the software or use pieces of it in new
 208  free programs, and that you know you can do these things.
 209  
 210    To protect your rights, we need to prevent others from denying you
 211  these rights or asking you to surrender the rights.  Therefore, you have
 212  certain responsibilities if you distribute copies of the software, or if
 213  you modify it: responsibilities to respect the freedom of others.
 214  
 215    For example, if you distribute copies of such a program, whether
 216  gratis or for a fee, you must pass on to the recipients the same
 217  freedoms that you received.  You must make sure that they, too, receive
 218  or can get the source code.  And you must show them these terms so they
 219  know their rights.
 220  
 221    Developers that use the GNU GPL protect your rights with two steps:
 222  (1) assert copyright on the software, and (2) offer you this License
 223  giving you legal permission to copy, distribute and/or modify it.
 224  
 225    For the developers' and authors' protection, the GPL clearly explains
 226  that there is no warranty for this free software.  For both users' and
 227  authors' sake, the GPL requires that modified versions be marked as
 228  changed, so that their problems will not be attributed erroneously to
 229  authors of previous versions.
 230  
 231    Some devices are designed to deny users access to install or run
 232  modified versions of the software inside them, although the manufacturer
 233  can do so.  This is fundamentally incompatible with the aim of
 234  protecting users' freedom to change the software.  The systematic
 235  pattern of such abuse occurs in the area of products for individuals to
 236  use, which is precisely where it is most unacceptable.  Therefore, we
 237  have designed this version of the GPL to prohibit the practice for those
 238  products.  If such problems arise substantially in other domains, we
 239  stand ready to extend this provision to those domains in future versions
 240  of the GPL, as needed to protect the freedom of users.
 241  
 242    Finally, every program is threatened constantly by software patents.
 243  States should not allow patents to restrict development and use of
 244  software on general-purpose computers, but in those that do, we wish to
 245  avoid the special danger that patents applied to a free program could
 246  make it effectively proprietary.  To prevent this, the GPL assures that
 247  patents cannot be used to render the program non-free.
 248  
 249    The precise terms and conditions for copying, distribution and
 250  modification follow.
 251  
 252                         TERMS AND CONDITIONS
 253  
 254    0. Definitions.
 255  
 256    "This License" refers to version 3 of the GNU General Public License.
 257  
 258    "Copyright" also means copyright-like laws that apply to other kinds of
 259  works, such as semiconductor masks.
 260  
 261    "The Program" refers to any copyrightable work licensed under this
 262  License.  Each licensee is addressed as "you".  "Licensees" and
 263  "recipients" may be individuals or organizations.
 264  
 265    To "modify" a work means to copy from or adapt all or part of the work
 266  in a fashion requiring copyright permission, other than the making of an
 267  exact copy.  The resulting work is called a "modified version" of the
 268  earlier work or a work "based on" the earlier work.
 269  
 270    A "covered work" means either the unmodified Program or a work based
 271  on the Program.
 272  
 273    To "propagate" a work means to do anything with it that, without
 274  permission, would make you directly or secondarily liable for
 275  infringement under applicable copyright law, except executing it on a
 276  computer or modifying a private copy.  Propagation includes copying,
 277  distribution (with or without modification), making available to the
 278  public, and in some countries other activities as well.
 279  
 280    To "convey" a work means any kind of propagation that enables other
 281  parties to make or receive copies.  Mere interaction with a user through
 282  a computer network, with no transfer of a copy, is not conveying.
 283  
 284    An interactive user interface displays "Appropriate Legal Notices"
 285  to the extent that it includes a convenient and prominently visible
 286  feature that (1) displays an appropriate copyright notice, and (2)
 287  tells the user that there is no warranty for the work (except to the
 288  extent that warranties are provided), that licensees may convey the
 289  work under this License, and how to view a copy of this License.  If
 290  the interface presents a list of user commands or options, such as a
 291  menu, a prominent item in the list meets this criterion.
 292  
 293    1. Source Code.
 294  
 295    The "source code" for a work means the preferred form of the work
 296  for making modifications to it.  "Object code" means any non-source
 297  form of a work.
 298  
 299    A "Standard Interface" means an interface that either is an official
 300  standard defined by a recognized standards body, or, in the case of
 301  interfaces specified for a particular programming language, one that
 302  is widely used among developers working in that language.
 303  
 304    The "System Libraries" of an executable work include anything, other
 305  than the work as a whole, that (a) is included in the normal form of
 306  packaging a Major Component, but which is not part of that Major
 307  Component, and (b) serves only to enable use of the work with that
 308  Major Component, or to implement a Standard Interface for which an
 309  implementation is available to the public in source code form.  A
 310  "Major Component", in this context, means a major essential component
 311  (kernel, window system, and so on) of the specific operating system
 312  (if any) on which the executable work runs, or a compiler used to
 313  produce the work, or an object code interpreter used to run it.
 314  
 315    The "Corresponding Source" for a work in object code form means all
 316  the source code needed to generate, install, and (for an executable
 317  work) run the object code and to modify the work, including scripts to
 318  control those activities.  However, it does not include the work's
 319  System Libraries, or general-purpose tools or generally available free
 320  programs which are used unmodified in performing those activities but
 321  which are not part of the work.  For example, Corresponding Source
 322  includes interface definition files associated with source files for
 323  the work, and the source code for shared libraries and dynamically
 324  linked subprograms that the work is specifically designed to require,
 325  such as by intimate data communication or control flow between those
 326  subprograms and other parts of the work.
 327  
 328    The Corresponding Source need not include anything that users
 329  can regenerate automatically from other parts of the Corresponding
 330  Source.
 331  
 332    The Corresponding Source for a work in source code form is that
 333  same work.
 334  
 335    2. Basic Permissions.
 336  
 337    All rights granted under this License are granted for the term of
 338  copyright on the Program, and are irrevocable provided the stated
 339  conditions are met.  This License explicitly affirms your unlimited
 340  permission to run the unmodified Program.  The output from running a
 341  covered work is covered by this License only if the output, given its
 342  content, constitutes a covered work.  This License acknowledges your
 343  rights of fair use or other equivalent, as provided by copyright law.
 344  
 345    You may make, run and propagate covered works that you do not
 346  convey, without conditions so long as your license otherwise remains
 347  in force.  You may convey covered works to others for the sole purpose
 348  of having them make modifications exclusively for you, or provide you
 349  with facilities for running those works, provided that you comply with
 350  the terms of this License in conveying all material for which you do
 351  not control copyright.  Those thus making or running the covered works
 352  for you must do so exclusively on your behalf, under your direction
 353  and control, on terms that prohibit them from making any copies of
 354  your copyrighted material outside their relationship with you.
 355  
 356    Conveying under any other circumstances is permitted solely under
 357  the conditions stated below.  Sublicensing is not allowed; section 10
 358  makes it unnecessary.
 359  
 360    3. Protecting Users' Legal Rights From Anti-Circumvention Law.
 361  
 362    No covered work shall be deemed part of an effective technological
 363  measure under any applicable law fulfilling obligations under article
 364  11 of the WIPO copyright treaty adopted on 20 December 1996, or
 365  similar laws prohibiting or restricting circumvention of such
 366  measures.
 367  
 368    When you convey a covered work, you waive any legal power to forbid
 369  circumvention of technological measures to the extent such circumvention
 370  is effected by exercising rights under this License with respect to
 371  the covered work, and you disclaim any intention to limit operation or
 372  modification of the work as a means of enforcing, against the work's
 373  users, your or third parties' legal rights to forbid circumvention of
 374  technological measures.
 375  
 376    4. Conveying Verbatim Copies.
 377  
 378    You may convey verbatim copies of the Program's source code as you
 379  receive it, in any medium, provided that you conspicuously and
 380  appropriately publish on each copy an appropriate copyright notice;
 381  keep intact all notices stating that this License and any
 382  non-permissive terms added in accord with section 7 apply to the code;
 383  keep intact all notices of the absence of any warranty; and give all
 384  recipients a copy of this License along with the Program.
 385  
 386    You may charge any price or no price for each copy that you convey,
 387  and you may offer support or warranty protection for a fee.
 388  
 389    5. Conveying Modified Source Versions.
 390  
 391    You may convey a work based on the Program, or the modifications to
 392  produce it from the Program, in the form of source code under the
 393  terms of section 4, provided that you also meet all of these conditions:
 394  
 395      a) The work must carry prominent notices stating that you modified
 396      it, and giving a relevant date.
 397  
 398      b) The work must carry prominent notices stating that it is
 399      released under this License and any conditions added under section
 400      7.  This requirement modifies the requirement in section 4 to
 401      "keep intact all notices".
 402  
 403      c) You must license the entire work, as a whole, under this
 404      License to anyone who comes into possession of a copy.  This
 405      License will therefore apply, along with any applicable section 7
 406      additional terms, to the whole of the work, and all its parts,
 407      regardless of how they are packaged.  This License gives no
 408      permission to license the work in any other way, but it does not
 409      invalidate such permission if you have separately received it.
 410  
 411      d) If the work has interactive user interfaces, each must display
 412      Appropriate Legal Notices; however, if the Program has interactive
 413      interfaces that do not display Appropriate Legal Notices, your
 414      work need not make them do so.
 415  
 416    A compilation of a covered work with other separate and independent
 417  works, which are not by their nature extensions of the covered work,
 418  and which are not combined with it such as to form a larger program,
 419  in or on a volume of a storage or distribution medium, is called an
 420  "aggregate" if the compilation and its resulting copyright are not
 421  used to limit the access or legal rights of the compilation's users
 422  beyond what the individual works permit.  Inclusion of a covered work
 423  in an aggregate does not cause this License to apply to the other
 424  parts of the aggregate.
 425  
 426    6. Conveying Non-Source Forms.
 427  
 428    You may convey a covered work in object code form under the terms
 429  of sections 4 and 5, provided that you also convey the
 430  machine-readable Corresponding Source under the terms of this License,
 431  in one of these ways:
 432  
 433      a) Convey the object code in, or embodied in, a physical product
 434      (including a physical distribution medium), accompanied by the
 435      Corresponding Source fixed on a durable physical medium
 436      customarily used for software interchange.
 437  
 438      b) Convey the object code in, or embodied in, a physical product
 439      (including a physical distribution medium), accompanied by a
 440      written offer, valid for at least three years and valid for as
 441      long as you offer spare parts or customer support for that product
 442      model, to give anyone who possesses the object code either (1) a
 443      copy of the Corresponding Source for all the software in the
 444      product that is covered by this License, on a durable physical
 445      medium customarily used for software interchange, for a price no
 446      more than your reasonable cost of physically performing this
 447      conveying of source, or (2) access to copy the
 448      Corresponding Source from a network server at no charge.
 449  
 450      c) Convey individual copies of the object code with a copy of the
 451      written offer to provide the Corresponding Source.  This
 452      alternative is allowed only occasionally and noncommercially, and
 453      only if you received the object code with such an offer, in accord
 454      with subsection 6b.
 455  
 456      d) Convey the object code by offering access from a designated
 457      place (gratis or for a charge), and offer equivalent access to the
 458      Corresponding Source in the same way through the same place at no
 459      further charge.  You need not require recipients to copy the
 460      Corresponding Source along with the object code.  If the place to
 461      copy the object code is a network server, the Corresponding Source
 462      may be on a different server (operated by you or a third party)
 463      that supports equivalent copying facilities, provided you maintain
 464      clear directions next to the object code saying where to find the
 465      Corresponding Source.  Regardless of what server hosts the
 466      Corresponding Source, you remain obligated to ensure that it is
 467      available for as long as needed to satisfy these requirements.
 468  
 469      e) Convey the object code using peer-to-peer transmission, provided
 470      you inform other peers where the object code and Corresponding
 471      Source of the work are being offered to the general public at no
 472      charge under subsection 6d.
 473  
 474    A separable portion of the object code, whose source code is excluded
 475  from the Corresponding Source as a System Library, need not be
 476  included in conveying the object code work.
 477  
 478    A "User Product" is either (1) a "consumer product", which means any
 479  tangible personal property which is normally used for personal, family,
 480  or household purposes, or (2) anything designed or sold for incorporation
 481  into a dwelling.  In determining whether a product is a consumer product,
 482  doubtful cases shall be resolved in favor of coverage.  For a particular
 483  product received by a particular user, "normally used" refers to a
 484  typical or common use of that class of product, regardless of the status
 485  of the particular user or of the way in which the particular user
 486  actually uses, or expects or is expected to use, the product.  A product
 487  is a consumer product regardless of whether the product has substantial
 488  commercial, industrial or non-consumer uses, unless such uses represent
 489  the only significant mode of use of the product.
 490  
 491    "Installation Information" for a User Product means any methods,
 492  procedures, authorization keys, or other information required to install
 493  and execute modified versions of a covered work in that User Product from
 494  a modified version of its Corresponding Source.  The information must
 495  suffice to ensure that the continued functioning of the modified object
 496  code is in no case prevented or interfered with solely because
 497  modification has been made.
 498  
 499    If you convey an object code work under this section in, or with, or
 500  specifically for use in, a User Product, and the conveying occurs as
 501  part of a transaction in which the right of possession and use of the
 502  User Product is transferred to the recipient in perpetuity or for a
 503  fixed term (regardless of how the transaction is characterized), the
 504  Corresponding Source conveyed under this section must be accompanied
 505  by the Installation Information.  But this requirement does not apply
 506  if neither you nor any third party retains the ability to install
 507  modified object code on the User Product (for example, the work has
 508  been installed in ROM).
 509  
 510    The requirement to provide Installation Information does not include a
 511  requirement to continue to provide support service, warranty, or updates
 512  for a work that has been modified or installed by the recipient, or for
 513  the User Product in which it has been modified or installed.  Access to a
 514  network may be denied when the modification itself materially and
 515  adversely affects the operation of the network or violates the rules and
 516  protocols for communication across the network.
 517  
 518    Corresponding Source conveyed, and Installation Information provided,
 519  in accord with this section must be in a format that is publicly
 520  documented (and with an implementation available to the public in
 521  source code form), and must require no special password or key for
 522  unpacking, reading or copying.
 523  
 524    7. Additional Terms.
 525  
 526    "Additional permissions" are terms that supplement the terms of this
 527  License by making exceptions from one or more of its conditions.
 528  Additional permissions that are applicable to the entire Program shall
 529  be treated as though they were included in this License, to the extent
 530  that they are valid under applicable law.  If additional permissions
 531  apply only to part of the Program, that part may be used separately
 532  under those permissions, but the entire Program remains governed by
 533  this License without regard to the additional permissions.
 534  
 535    When you convey a copy of a covered work, you may at your option
 536  remove any additional permissions from that copy, or from any part of
 537  it.  (Additional permissions may be written to require their own
 538  removal in certain cases when you modify the work.)  You may place
 539  additional permissions on material, added by you to a covered work,
 540  for which you have or can give appropriate copyright permission.
 541  
 542    Notwithstanding any other provision of this License, for material you
 543  add to a covered work, you may (if authorized by the copyright holders of
 544  that material) supplement the terms of this License with terms:
 545  
 546      a) Disclaiming warranty or limiting liability differently from the
 547      terms of sections 15 and 16 of this License; or
 548  
 549      b) Requiring preservation of specified reasonable legal notices or
 550      author attributions in that material or in the Appropriate Legal
 551      Notices displayed by works containing it; or
 552  
 553      c) Prohibiting misrepresentation of the origin of that material, or
 554      requiring that modified versions of such material be marked in
 555      reasonable ways as different from the original version; or
 556  
 557      d) Limiting the use for publicity purposes of names of licensors or
 558      authors of the material; or
 559  
 560      e) Declining to grant rights under trademark law for use of some
 561      trade names, trademarks, or service marks; or
 562  
 563      f) Requiring indemnification of licensors and authors of that
 564      material by anyone who conveys the material (or modified versions of
 565      it) with contractual assumptions of liability to the recipient, for
 566      any liability that these contractual assumptions directly impose on
 567      those licensors and authors.
 568  
 569    All other non-permissive additional terms are considered "further
 570  restrictions" within the meaning of section 10.  If the Program as you
 571  received it, or any part of it, contains a notice stating that it is
 572  governed by this License along with a term that is a further
 573  restriction, you may remove that term.  If a license document contains
 574  a further restriction but permits relicensing or conveying under this
 575  License, you may add to a covered work material governed by the terms
 576  of that license document, provided that the further restriction does
 577  not survive such relicensing or conveying.
 578  
 579    If you add terms to a covered work in accord with this section, you
 580  must place, in the relevant source files, a statement of the
 581  additional terms that apply to those files, or a notice indicating
 582  where to find the applicable terms.
 583  
 584    Additional terms, permissive or non-permissive, may be stated in the
 585  form of a separately written license, or stated as exceptions;
 586  the above requirements apply either way.
 587  
 588    8. Termination.
 589  
 590    You may not propagate or modify a covered work except as expressly
 591  provided under this License.  Any attempt otherwise to propagate or
 592  modify it is void, and will automatically terminate your rights under
 593  this License (including any patent licenses granted under the third
 594  paragraph of section 11).
 595  
 596    However, if you cease all violation of this License, then your
 597  license from a particular copyright holder is reinstated (a)
 598  provisionally, unless and until the copyright holder explicitly and
 599  finally terminates your license, and (b) permanently, if the copyright
 600  holder fails to notify you of the violation by some reasonable means
 601  prior to 60 days after the cessation.
 602  
 603    Moreover, your license from a particular copyright holder is
 604  reinstated permanently if the copyright holder notifies you of the
 605  violation by some reasonable means, this is the first time you have
 606  received notice of violation of this License (for any work) from that
 607  copyright holder, and you cure the violation prior to 30 days after
 608  your receipt of the notice.
 609  
 610    Termination of your rights under this section does not terminate the
 611  licenses of parties who have received copies or rights from you under
 612  this License.  If your rights have been terminated and not permanently
 613  reinstated, you do not qualify to receive new licenses for the same
 614  material under section 10.
 615  
 616    9. Acceptance Not Required for Having Copies.
 617  
 618    You are not required to accept this License in order to receive or
 619  run a copy of the Program.  Ancillary propagation of a covered work
 620  occurring solely as a consequence of using peer-to-peer transmission
 621  to receive a copy likewise does not require acceptance.  However,
 622  nothing other than this License grants you permission to propagate or
 623  modify any covered work.  These actions infringe copyright if you do
 624  not accept this License.  Therefore, by modifying or propagating a
 625  covered work, you indicate your acceptance of this License to do so.
 626  
 627    10. Automatic Licensing of Downstream Recipients.
 628  
 629    Each time you convey a covered work, the recipient automatically
 630  receives a license from the original licensors, to run, modify and
 631  propagate that work, subject to this License.  You are not responsible
 632  for enforcing compliance by third parties with this License.
 633  
 634    An "entity transaction" is a transaction transferring control of an
 635  organization, or substantially all assets of one, or subdividing an
 636  organization, or merging organizations.  If propagation of a covered
 637  work results from an entity transaction, each party to that
 638  transaction who receives a copy of the work also receives whatever
 639  licenses to the work the party's predecessor in interest had or could
 640  give under the previous paragraph, plus a right to possession of the
 641  Corresponding Source of the work from the predecessor in interest, if
 642  the predecessor has it or can get it with reasonable efforts.
 643  
 644    You may not impose any further restrictions on the exercise of the
 645  rights granted or affirmed under this License.  For example, you may
 646  not impose a license fee, royalty, or other charge for exercise of
 647  rights granted under this License, and you may not initiate litigation
 648  (including a cross-claim or counterclaim in a lawsuit) alleging that
 649  any patent claim is infringed by making, using, selling, offering for
 650  sale, or importing the Program or any portion of it.
 651  
 652    11. Patents.
 653  
 654    A "contributor" is a copyright holder who authorizes use under this
 655  License of the Program or a work on which the Program is based.  The
 656  work thus licensed is called the contributor's "contributor version".
 657  
 658    A contributor's "essential patent claims" are all patent claims
 659  owned or controlled by the contributor, whether already acquired or
 660  hereafter acquired, that would be infringed by some manner, permitted
 661  by this License, of making, using, or selling its contributor version,
 662  but do not include claims that would be infringed only as a
 663  consequence of further modification of the contributor version.  For
 664  purposes of this definition, "control" includes the right to grant
 665  patent sublicenses in a manner consistent with the requirements of
 666  this License.
 667  
 668    Each contributor grants you a non-exclusive, worldwide, royalty-free
 669  patent license under the contributor's essential patent claims, to
 670  make, use, sell, offer for sale, import and otherwise run, modify and
 671  propagate the contents of its contributor version.
 672  
 673    In the following three paragraphs, a "patent license" is any express
 674  agreement or commitment, however denominated, not to enforce a patent
 675  (such as an express permission to practice a patent or covenant not to
 676  sue for patent infringement).  To "grant" such a patent license to a
 677  party means to make such an agreement or commitment not to enforce a
 678  patent against the party.
 679  
 680    If you convey a covered work, knowingly relying on a patent license,
 681  and the Corresponding Source of the work is not available for anyone
 682  to copy, free of charge and under the terms of this License, through a
 683  publicly available network server or other readily accessible means,
 684  then you must either (1) cause the Corresponding Source to be so
 685  available, or (2) arrange to deprive yourself of the benefit of the
 686  patent license for this particular work, or (3) arrange, in a manner
 687  consistent with the requirements of this License, to extend the patent
 688  license to downstream recipients.  "Knowingly relying" means you have
 689  actual knowledge that, but for the patent license, your conveying the
 690  covered work in a country, or your recipient's use of the covered work
 691  in a country, would infringe one or more identifiable patents in that
 692  country that you have reason to believe are valid.
 693  
 694    If, pursuant to or in connection with a single transaction or
 695  arrangement, you convey, or propagate by procuring conveyance of, a
 696  covered work, and grant a patent license to some of the parties
 697  receiving the covered work authorizing them to use, propagate, modify
 698  or convey a specific copy of the covered work, then the patent license
 699  you grant is automatically extended to all recipients of the covered
 700  work and works based on it.
 701  
 702    A patent license is "discriminatory" if it does not include within
 703  the scope of its coverage, prohibits the exercise of, or is
 704  conditioned on the non-exercise of one or more of the rights that are
 705  specifically granted under this License.  You may not convey a covered
 706  work if you are a party to an arrangement with a third party that is
 707  in the business of distributing software, under which you make payment
 708  to the third party based on the extent of your activity of conveying
 709  the work, and under which the third party grants, to any of the
 710  parties who would receive the covered work from you, a discriminatory
 711  patent license (a) in connection with copies of the covered work
 712  conveyed by you (or copies made from those copies), or (b) primarily
 713  for and in connection with specific products or compilations that
 714  contain the covered work, unless you entered into that arrangement,
 715  or that patent license was granted, prior to 28 March 2007.
 716  
 717    Nothing in this License shall be construed as excluding or limiting
 718  any implied license or other defenses to infringement that may
 719  otherwise be available to you under applicable patent law.
 720  
 721    12. No Surrender of Others' Freedom.
 722  
 723    If conditions are imposed on you (whether by court order, agreement or
 724  otherwise) that contradict the conditions of this License, they do not
 725  excuse you from the conditions of this License.  If you cannot convey a
 726  covered work so as to satisfy simultaneously your obligations under this
 727  License and any other pertinent obligations, then as a consequence you may
 728  not convey it at all.  For example, if you agree to terms that obligate you
 729  to collect a royalty for further conveying from those to whom you convey
 730  the Program, the only way you could satisfy both those terms and this
 731  License would be to refrain entirely from conveying the Program.
 732  
 733    13. Use with the GNU Affero General Public License.
 734  
 735    Notwithstanding any other provision of this License, you have
 736  permission to link or combine any covered work with a work licensed
 737  under version 3 of the GNU Affero General Public License into a single
 738  combined work, and to convey the resulting work.  The terms of this
 739  License will continue to apply to the part which is the covered work,
 740  but the special requirements of the GNU Affero General Public License,
 741  section 13, concerning interaction through a network will apply to the
 742  combination as such.
 743  
 744    14. Revised Versions of this License.
 745  
 746    The Free Software Foundation may publish revised and/or new versions of
 747  the GNU General Public License from time to time.  Such new versions will
 748  be similar in spirit to the present version, but may differ in detail to
 749  address new problems or concerns.
 750  
 751    Each version is given a distinguishing version number.  If the
 752  Program specifies that a certain numbered version of the GNU General
 753  Public License "or any later version" applies to it, you have the
 754  option of following the terms and conditions either of that numbered
 755  version or of any later version published by the Free Software
 756  Foundation.  If the Program does not specify a version number of the
 757  GNU General Public License, you may choose any version ever published
 758  by the Free Software Foundation.
 759  
 760    If the Program specifies that a proxy can decide which future
 761  versions of the GNU General Public License can be used, that proxy's
 762  public statement of acceptance of a version permanently authorizes you
 763  to choose that version for the Program.
 764  
 765    Later license versions may give you additional or different
 766  permissions.  However, no additional obligations are imposed on any
 767  author or copyright holder as a result of your choosing to follow a
 768  later version.
 769  
 770    15. Disclaimer of Warranty.
 771  
 772    THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
 773  APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
 774  HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
 775  OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
 776  THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
 777  PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
 778  IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
 779  ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
 780  
 781    16. Limitation of Liability.
 782  
 783    IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
 784  WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
 785  THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
 786  GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
 787  USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
 788  DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
 789  PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
 790  EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
 791  SUCH DAMAGES.
 792  
 793    17. Interpretation of Sections 15 and 16.
 794  
 795    If the disclaimer of warranty and limitation of liability provided
 796  above cannot be given local legal effect according to their terms,
 797  reviewing courts shall apply local law that most closely approximates
 798  an absolute waiver of all civil liability in connection with the
 799  Program, unless a warranty or assumption of liability accompanies a
 800  copy of the Program in return for a fee.
 801  
 802                       END OF TERMS AND CONDITIONS
 803  
 804              How to Apply These Terms to Your New Programs
 805  
 806    If you develop a new program, and you want it to be of the greatest
 807  possible use to the public, the best way to achieve this is to make it
 808  free software which everyone can redistribute and change under these terms.
 809  
 810    To do so, attach the following notices to the program.  It is safest
 811  to attach them to the start of each source file to most effectively
 812  state the exclusion of warranty; and each file should have at least
 813  the "copyright" line and a pointer to where the full notice is found.
 814  
 815      <one line to give the program's name and a brief idea of what it does.>
 816      Copyright (C) <year>  <name of author>
 817  
 818      This program is free software: you can redistribute it and/or modify
 819      it under the terms of the GNU General Public License as published by
 820      the Free Software Foundation, either version 3 of the License, or
 821      (at your option) any later version.
 822  
 823      This program is distributed in the hope that it will be useful,
 824      but WITHOUT ANY WARRANTY; without even the implied warranty of
 825      MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
 826      GNU General Public License for more details.
 827  
 828      You should have received a copy of the GNU General Public License
 829      along with this program.  If not, see <http://www.gnu.org/licenses/>.
 830  
 831  Also add information on how to contact you by electronic and paper mail.
 832  
 833    If the program does terminal interaction, make it output a short
 834  notice like this when it starts in an interactive mode:
 835  
 836      <program>  Copyright (C) <year>  <name of author>
 837      This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
 838      This is free software, and you are welcome to redistribute it
 839      under certain conditions; type `show c' for details.
 840  
 841  The hypothetical commands `show w' and `show c' should show the appropriate
 842  parts of the General Public License.  Of course, your program's commands
 843  might be different; for a GUI interface, you would use an "about box".
 844  
 845    You should also get your employer (if you work as a programmer) or school,
 846  if any, to sign a "copyright disclaimer" for the program, if necessary.
 847  For more information on this, and how to apply and follow the GNU GPL, see
 848  <http://www.gnu.org/licenses/>.
 849  
 850    The GNU General Public License does not permit incorporating your program
 851  into proprietary programs.  If your program is a subroutine library, you
 852  may consider it more useful to permit linking proprietary applications with
 853  the library.  If this is what you want to do, use the GNU Lesser General
 854  Public License instead of this License.  But first, please read
 855  <http://www.gnu.org/philosophy/why-not-lgpl.html>.
