 Everyone is permitted to copy and distribute verbatim copies
Martin@1
     6
 of this license document, but changing it is not allowed.

                            Preamble
Martin@1
     9
Martin@1
    10
  The GNU General Public License is a free, copyleft license for
Martin@1
    11
software and other kinds of works.
Martin@1
    12
Martin@1
    13
  The licenses for most software and other practical works are designed
Martin@1
    14
to take away your freedom to share and change the works.  By contrast,
Martin@1
    15
the GNU General Public License is intended to guarantee your freedom to
Martin@1
    16
share and change all versions of a program--to make sure it remains free
Martin@1
    17
software for all its users.  We, the Free Software Foundation, use the
Martin@1
    18
GNU General Public License for most of our software; it applies also to
Martin@1
    19
any other work released this way by its authors.  You can apply it to
Martin@1
    20
your programs, too.
Martin@1
    21
Martin@1
    22
  When we speak of free software, we are referring to freedom, not
Martin@1
    23
price.  Our General Public Licenses are designed to make sure that you
Martin@1
    24
have the freedom to distribute copies of free software (and charge for
Martin@1
    25
them if you wish), that you receive source code or can get it if you
Martin@1
    26
want it, that you can change the software or use pieces of it in new
Martin@1
    27
free programs, and that you know you can do these things.
Martin@1
    28
Martin@1
    29
  To protect your rights, we need to prevent others from denying you
Martin@1
    30
these rights or asking you to surrender the rights.  Therefore, you have
Martin@1
    31
certain responsibilities if you distribute copies of the software, or if
Martin@1
    32
you modify it: responsibilities to respect the freedom of others.
Martin@1
    33
Martin@1
    34
  For example, if you distribute copies of such a program, whether
Martin@1
    35
gratis or for a fee, you must pass on to the recipients the same
Martin@1
    36
freedoms that you received.  You must make sure that they, too, receive
Martin@1
    37
or can get the source code.  And you must show them these terms so they
Martin@1
    38
know their rights.
Martin@1
    39
Martin@1
    40
  Developers that use the GNU GPL protect your rights with two steps:
Martin@1
    41
(1) assert copyright on the software, and (2) offer you this License
Martin@1
    42
giving you legal permission to copy, distribute and/or modify it.
Martin@1
    43
Martin@1
    44
  For the developers' and authors' protection, the GPL clearly explains
Martin@1
    45
that there is no warranty for this free software.  For both users' and
Martin@1
    46
authors' sake, the GPL requires that modified versions be marked as
Martin@1
    47
changed, so that their problems will not be attributed erroneously to
Martin@1
    48
authors of previous versions.
Martin@1
    49
Martin@1
    50
  Some devices are designed to deny users access to install or run
Martin@1
    51
modified versions of the software inside them, although the manufacturer
Martin@1
    52
can do so.  This is fundamentally incompatible with the aim of
Martin@1
    53
protecting users' freedom to change the software.  The systematic
Martin@1
    54
pattern of such abuse occurs in the area of products for individuals to
Martin@1
    55
use, which is precisely where it is most unacceptable.  Therefore, we
Martin@1
    56
have designed this version of the GPL to prohibit the practice for those
Martin@1
    57
products.  If such problems arise substantially in other domains, we
Martin@1
    58
stand ready to extend this provision to those domains in future versions
Martin@1
    59
of the GPL, as needed to protect the freedom of users.
Martin@1
    60
Martin@1
    61
  Finally, every program is threatened constantly by software patents.
Martin@1
    62
States should not allow patents to restrict development and use of
Martin@1
    63
software on general-purpose computers, but in those that do, we wish to
Martin@1
    64
avoid the special danger that patents applied to a free program could
Martin@1
    65
make it effectively proprietary.  To prevent this, the GPL assures that
Martin@1
    66
patents cannot be used to render the program non-free.
Martin@1
    67
Martin@1
    68
  The precise terms and conditions for copying, distribution and
Martin@1
    69
modification follow.
Martin@1
    70
Martin@1
    71
                       TERMS AND CONDITIONS
Martin@1
    72
Martin@1
    73
  0. Definitions.
Martin@1
    74
Martin@1
    75
  "This License" refers to version 3 of the GNU General Public License.
Martin@1
    76
Martin@1
    77
  "Copyright" also means copyright-like laws that apply to other kinds of
Martin@1
    78
works, such as semiconductor masks.
Martin@1
    79
Martin@1
    80
  "The Program" refers to any copyrightable work licensed under this
Martin@1
    81
License.  Each licensee is addressed as "you".  "Licensees" and
Martin@1
    82
"recipients" may be individuals or organizations.
Martin@1
    83
Martin@1
    84
  To "modify" a work means to copy from or adapt all or part of the work
Martin@1
    85
in a fashion requiring copyright permission, other than the making of an
Martin@1
    86
exact copy.  The resulting work is called a "modified version" of the
Martin@1
    87
earlier work or a work "based on" the earlier work.
Martin@1
    88
Martin@1
    89
  A "covered work" means either the unmodified Program or a work based
Martin@1
    90
on the Program.
Martin@1
    91
Martin@1
    92
  To "propagate" a work means to do anything with it that, without
Martin@1
    93
permission, would make you directly or secondarily liable for
Martin@1
    94
infringement under applicable copyright law, except executing it on a
Martin@1
    95
computer or modifying a private copy.  Propagation includes copying,
Martin@1
    96
distribution (with or without modification), making available to the
Martin@1
    97
public, and in some countries other activities as well.
Martin@1
    98
Martin@1
    99
  To "convey" a work means any kind of propagation that enables other
Martin@1
   100
parties to make or receive copies.  Mere interaction with a user through
Martin@1
   101
a computer network, with no transfer of a copy, is not conveying.
Martin@1
   102
Martin@1
   103
  An interactive user interface displays "Appropriate Legal Notices"
Martin@1
   104
to the extent that it includes a convenient and prominently visible
Martin@1
   105
feature that (1) displays an appropriate copyright notice, and (2)
Martin@1
   106
tells the user that there is no warranty for the work (except to the
Martin@1
   107
extent that warranties are provided), that licensees may convey the
Martin@1
   108
work under this License, and how to view a copy of this License.  If
Martin@1
   109
the interface presents a list of user commands or options, such as a
Martin@1
   110
menu, a prominent item in the list meets this criterion.
Martin@1
   111
Martin@1
   112
  1. Source Code.
Martin@1
   113
Martin@1
   114
  The "source code" for a work means the preferred form of the work
Martin@1
   115
for making modifications to it.  "Object code" means any non-source
Martin@1
   116
form of a work.
Martin@1
   117
Martin@1
   118
  A "Standard Interface" means an interface that either is an official
Martin@1
   119
standard defined by a recognized standards body, or, in the case of
Martin@1
   120
interfaces specified for a particular programming language, one that
Martin@1
   121
is widely used among developers working in that language.
Martin@1
   122
Martin@1
   123
  The "System Libraries" of an executable work include anything, other
Martin@1
   124
than the work as a whole, that (a) is included in the normal form of
Martin@1
   125
packaging a Major Component, but which is not part of that Major
Martin@1
   126
Component, and (b) serves only to enable use of the work with that
Martin@1
   127
Major Component, or to implement a Standard Interface for which an
Martin@1
   128
implementation is available to the public in source code form.  A
Martin@1
   129
"Major Component", in this context, means a major essential component
Martin@1
   130
(kernel, window system, and so on) of the specific operating system
Martin@1
   131
(if any) on which the executable work runs, or a compiler used to
Martin@1
   132
produce the work, or an object code interpreter used to run it.
Martin@1
   133
Martin@1
   134
  The "Corresponding Source" for a work in object code form means all
Martin@1
   135
the source code needed to generate, install, and (for an executable
Martin@1
   136
work) run the object code and to modify the work, including scripts to
Martin@1
   137
control those activities.  However, it does not include the work's
Martin@1
   138
System Libraries, or general-purpose tools or generally available free
Martin@1
   139
programs which are used unmodified in performing those activities but
Martin@1
   140
which are not part of the work.  For example, Corresponding Source
Martin@1
   141
includes interface definition files associated with source files for
Martin@1
   142
the work, and the source code for shared libraries and dynamically
Martin@1
   143
linked subprograms that the work is specifically designed to require,
Martin@1
   144
such as by intimate data communication or control flow between those
Martin@1
   145
subprograms and other parts of the work.
Martin@1
   146
Martin@1
   147
  The Corresponding Source need not include anything that users
Martin@1
   148
can regenerate automatically from other parts of the Corresponding
Martin@1
   149
Source.
Martin@1
   150
Martin@1
   151
  The Corresponding Source for a work in source code form is that
Martin@1
   152
same work.
Martin@1
   153
Martin@1
   154
  2. Basic Permissions.
Martin@1
   155
Martin@1
   156
  All rights granted under this License are granted for the term of
Martin@1
   157
copyright on the Program, and are irrevocable provided the stated
Martin@1
   158
conditions are met.  This License explicitly affirms your unlimited
Martin@1
   159
permission to run the unmodified Program.  The output from running a
Martin@1
   160
covered work is covered by this License only if the output, given its
Martin@1
   161
content, constitutes a covered work.  This License acknowledges your
Martin@1
   162
rights of fair use or other equivalent, as provided by copyright law.
Martin@1
   163
Martin@1
   164
  You may make, run and propagate covered works that you do not
Martin@1
   165
convey, without conditions so long as your license otherwise remains
Martin@1
   166
in force.  You may convey covered works to others for the sole purpose
Martin@1
   167
of having them make modifications exclusively for you, or provide you
Martin@1
   168
with facilities for running those works, provided that you comply with
Martin@1
   169
the terms of this License in conveying all material for which you do
Martin@1
   170
not control copyright.  Those thus making or running the covered works
Martin@1
   171
for you must do so exclusively on your behalf, under your direction
Martin@1
   172
and control, on terms that prohibit them from making any copies of
Martin@1
   173
your copyrighted material outside their relationship with you.
Martin@1
   174
Martin@1
   175
  Conveying under any other circumstances is permitted solely under
Martin@1
   176
the conditions stated below.  Sublicensing is not allowed; section 10
Martin@1
   177
makes it unnecessary.
Martin@1
   178
Martin@1
   179
  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
Martin@1
   180
Martin@1
   181
  No covered work shall be deemed part of an effective technological
Martin@1
   182
measure under any applicable law fulfilling obligations under article
Martin@1
   183
11 of the WIPO copyright treaty adopted on 20 December 1996, or
Martin@1
   184
similar laws prohibiting or restricting circumvention of such
Martin@1
   185
measures.
Martin@1
   186
Martin@1
   187
  When you convey a covered work, you waive any legal power to forbid
Martin@1
   188
circumvention of technological measures to the extent such circumvention
Martin@1
   189
is effected by exercising rights under this License with respect to
Martin@1
   190
the covered work, and you disclaim any intention to limit operation or
Martin@1
   191
modification of the work as a means of enforcing, against the work's
Martin@1
   192
users, your or third parties' legal rights to forbid circumvention of
Martin@1
   193
technological measures.
Martin@1
   194
Martin@1
   195
  4. Conveying Verbatim Copies.
Martin@1
   196
Martin@1
   197
  You may convey verbatim copies of the Program's source code as you
Martin@1
   198
receive it, in any medium, provided that you conspicuously and
Martin@1
   199
appropriately publish on each copy an appropriate copyright notice;
Martin@1
   200
keep intact all notices stating that this License and any
Martin@1
   201
non-permissive terms added in accord with section 7 apply to the code;
Martin@1
   202
keep intact all notices of the absence of any warranty; and give all
Martin@1
   203
recipients a copy of this License along with the Program.
Martin@1
   204
Martin@1
   205
  You may charge any price or no price for each copy that you convey,
Martin@1
   206
and you may offer support or warranty protection for a fee.
Martin@1
   207
Martin@1
   208
  5. Conveying Modified Source Versions.
Martin@1
   209
Martin@1
   210
  You may convey a work based on the Program, or the modifications to
Martin@1
   211
produce it from the Program, in the form of source code under the
Martin@1
   212
terms of section 4, provided that you also meet all of these conditions:
Martin@1
   213
Martin@1
   214
    a) The work must carry prominent notices stating that you modified
Martin@1
   215
    it, and giving a relevant date.
Martin@1
   216
Martin@1
   217
    b) The work must carry prominent notices stating that it is
Martin@1
   218
    released under this License and any conditions added under section
Martin@1
   219
    7.  This requirement modifies the requirement in section 4 to
Martin@1
   220
    "keep intact all notices".
Martin@1
   221
Martin@1
   222
    c) You must license the entire work, as a whole, under this
Martin@1
   223
    License to anyone who comes into possession of a copy.  This
Martin@1
   224
    License will therefore apply, along with any applicable section 7
Martin@1
   225
    additional terms, to the whole of the work, and all its parts,
Martin@1
   226
    regardless of how they are packaged.  This License gives no
Martin@1
   227
    permission to license the work in any other way, but it does not
Martin@1
   228
    invalidate such permission if you have separately received it.
Martin@1
   229
Martin@1
   230
    d) If the work has interactive user interfaces, each must display
Martin@1
   231
    Appropriate Legal Notices; however, if the Program has interactive
Martin@1
   232
    interfaces that do not display Appropriate Legal Notices, your
Martin@1
   233
    work need not make them do so.
Martin@1
   234
Martin@1
   235
  A compilation of a covered work with other separate and independent
Martin@1
   236
works, which are not by their nature extensions of the covered work,
Martin@1
   237
and which are not combined with it such as to form a larger program,
Martin@1
   238
in or on a volume of a storage or distribution medium, is called an
Martin@1
   239
"aggregate" if the compilation and its resulting copyright are not
Martin@1
   240
used to limit the access or legal rights of the compilation's users
Martin@1
   241
beyond what the individual works permit.  Inclusion of a covered work
Martin@1
   242
in an aggregate does not cause this License to apply to the other
Martin@1
   243
parts of the aggregate.
Martin@1
   244
Martin@1
   245
  6. Conveying Non-Source Forms.
Martin@1
   246
Martin@1
   247
  You may convey a covered work in object code form under the terms
Martin@1
   248
of sections 4 and 5, provided that you also convey the
Martin@1
   249
machine-readable Corresponding Source under the terms of this License,
Martin@1
   250
in one of these ways:
Martin@1
   251
Martin@1
   252
    a) Convey the object code in, or embodied in, a physical product
Martin@1
   253
    (including a physical distribution medium), accompanied by the
Martin@1
   254
    Corresponding Source fixed on a durable physical medium
Martin@1
   255
    customarily used for software interchange.
Martin@1
   256
Martin@1
   257
    b) Convey the object code in, or embodied in, a physical product
Martin@1
   258
    (including a physical distribution medium), accompanied by a
Martin@1
   259
    written offer, valid for at least three years and valid for as
Martin@1
   260
    long as you offer spare parts or customer support for that product
Martin@1
   261
    model, to give anyone who possesses the object code either (1) a
Martin@1
   262
    copy of the Corresponding Source for all the software in the
Martin@1
   263
    product that is covered by this License, on a durable physical
Martin@1
   264
    medium customarily used for software interchange, for a price no
Martin@1
   265
    more than your reasonable cost of physically performing this
Martin@1
   266
    conveying of source, or (2) access to copy the
Martin@1
   267
    Corresponding Source from a network server at no charge.
Martin@1
   268
Martin@1
   269
    c) Convey individual copies of the object code with a copy of the
Martin@1
   270
    written offer to provide the Corresponding Source.  This
Martin@1
   271
    alternative is allowed only occasionally and noncommercially, and
Martin@1
   272
    only if you received the object code with such an offer, in accord
Martin@1
   273
    with subsection 6b.
Martin@1
   274
Martin@1
   275
    d) Convey the object code by offering access from a designated
Martin@1
   276
    place (gratis or for a charge), and offer equivalent access to the
Martin@1
   277
    Corresponding Source in the same way through the same place at no
Martin@1
   278
    further charge.  You need not require recipients to copy the
Martin@1
   279
    Corresponding Source along with the object code.  If the place to
Martin@1
   280
    copy the object code is a network server, the Corresponding Source
Martin@1
   281
    may be on a different server (operated by you or a third party)
Martin@1
   282
    that supports equivalent copying facilities, provided you maintain
Martin@1
   283
    clear directions next to the object code saying where to find the
Martin@1
   284
    Corresponding Source.  Regardless of what server hosts the
Martin@1
   285
    Corresponding Source, you remain obligated to ensure that it is
Martin@1
   286
    available for as long as needed to satisfy these requirements.
Martin@1
   287
Martin@1
   288
    e) Convey the object code using peer-to-peer transmission, provided
Martin@1
   289
    you inform other peers where the object code and Corresponding
Martin@1
   290
    Source of the work are being offered to the general public at no
Martin@1
   291
    charge under subsection 6d.
Martin@1
   292
Martin@1
   293
  A separable portion of the object code, whose source code is excluded
Martin@1
   294
from the Corresponding Source as a System Library, need not be
Martin@1
   295
included in conveying the object code work.
Martin@1
   296
Martin@1
   297
  A "User Product" is either (1) a "consumer product", which means any
Martin@1
   298
tangible personal property which is normally used for personal, family,
Martin@1
   299
or household purposes, or (2) anything designed or sold for incorporation
Martin@1
   300
into a dwelling.  In determining whether a product is a consumer product,
Martin@1
   301
doubtful cases shall be resolved in favor of coverage.  For a particular
Martin@1
   302
product received by a particular user, "normally used" refers to a
Martin@1
   303
typical or common use of that class of product, regardless of the status
Martin@1
   304
of the particular user or of the way in which the particular user
Martin@1
   305
actually uses, or expects or is expected to use, the product.  A product
Martin@1
   306
is a consumer product regardless of whether the product has substantial
Martin@1
   307
commercial, industrial or non-consumer uses, unless such uses represent
Martin@1
   308
the only significant mode of use of the product.
Martin@1
   309
Martin@1
   310
  "Installation Information" for a User Product means any methods,
Martin@1
   311
procedures, authorization keys, or other information required to install
Martin@1
   312
and execute modified versions of a covered work in that User Product from
Martin@1
   313
a modified version of its Corresponding Source.  The information must
Martin@1
   314
suffice to ensure that the continued functioning of the modified object
Martin@1
   315
code is in no case prevented or interfered with solely because
Martin@1
   316
modification has been made.
Martin@1
   317
Martin@1
   318
  If you convey an object code work under this section in, or with, or
Martin@1
   319
specifically for use in, a User Product, and the conveying occurs as
Martin@1
   320
part of a transaction in which the right of possession and use of the
Martin@1
   321
User Product is transferred to the recipient in perpetuity or for a
Martin@1
   322
fixed term (regardless of how the transaction is characterized), the
Martin@1
   323
Corresponding Source conveyed under this section must be accompanied
Martin@1
   324
by the Installation Information.  But this requirement does not apply
Martin@1
   325
if neither you nor any third party retains the ability to install
Martin@1
   326
modified object code on the User Product (for example, the work has
Martin@1
   327
been installed in ROM).
Martin@1
   328
Martin@1
   329
  The requirement to provide Installation Information does not include a
Martin@1
   330
requirement to continue to provide support service, warranty, or updates
Martin@1
   331
for a work that has been modified or installed by the recipient, or for
Martin@1
   332
the User Product in which it has been modified or installed.  Access to a
Martin@1
   333
network may be denied when the modification itself materially and
Martin@1
   334
adversely affects the operation of the network or violates the rules and
Martin@1
   335
protocols for communication across the network.
Martin@1
   336
Martin@1
   337
  Corresponding Source conveyed, and Installation Information provided,
Martin@1
   338
in accord with this section must be in a format that is publicly
Martin@1
   339
documented (and with an implementation available to the public in
Martin@1
   340
source code form), and must require no special password or key for
Martin@1
   341
unpacking, reading or copying.
Martin@1
   342
Martin@1
   343
  7. Additional Terms.
Martin@1
   344
Martin@1
   345
  "Additional permissions" are terms that supplement the terms of this
Martin@1
   346
License by making exceptions from one or more of its conditions.
Martin@1
   347
Additional permissions that are applicable to the entire Program shall
Martin@1
   348
be treated as though they were included in this License, to the extent
Martin@1
   349
that they are valid under applicable law.  If additional permissions
Martin@1
   350
apply only to part of the Program, that part may be used separately
Martin@1
   351
under those permissions, but the entire Program remains governed by
Martin@1
   352
this License without regard to the additional permissions.
Martin@1
   353
Martin@1
   354
  When you convey a copy of a covered work, you may at your option
Martin@1
   355
remove any additional permissions from that copy, or from any part of
Martin@1
   356
it.  (Additional permissions may be written to require their own
Martin@1
   357
removal in certain cases when you modify the work.)  You may place
Martin@1
   358
additional permissions on material, added by you to a covered work,
Martin@1
   359
for which you have or can give appropriate copyright permission.
Martin@1
   360
Martin@1
   361
  Notwithstanding any other provision of this License, for material you
Martin@1
   362
add to a covered work, you may (if authorized by the copyright holders of
Martin@1
   363
that material) supplement the terms of this License with terms:
Martin@1
   364
Martin@1
   365
    a) Disclaiming warranty or limiting liability differently from the
Martin@1
   366
    terms of sections 15 and 16 of this License; or
Martin@1
   367
Martin@1
   368
    b) Requiring preservation of specified reasonable legal notices or
Martin@1
   369
    author attributions in that material or in the Appropriate Legal
Martin@1
   370
    Notices displayed by works containing it; or
Martin@1
   371
Martin@1
   372
    c) Prohibiting misrepresentation of the origin of that material, or
Martin@1
   373
    requiring that modified versions of such material be marked in
Martin@1
   374
    reasonable ways as different from the original version; or
Martin@1
   375
Martin@1
   376
    d) Limiting the use for publicity purposes of names of licensors or
Martin@1
   377
    authors of the material; or
Martin@1
   378
Martin@1
   379
    e) Declining to grant rights under trademark law for use of some
Martin@1
   380
    trade names, trademarks, or service marks; or
Martin@1
   381
Martin@1
   382
    f) Requiring indemnification of licensors and authors of that
Martin@1
   383
    material by anyone who conveys the material (or modified versions of
Martin@1
   384
    it) with contractual assumptions of liability to the recipient, for
Martin@1
   385
    any liability that these contractual assumptions directly impose on
Martin@1
   386
    those licensors and authors.
Martin@1
   387
Martin@1
   388
  All other non-permissive additional terms are considered "further
Martin@1
   389
restrictions" within the meaning of section 10.  If the Program as you
Martin@1
   390
received it, or any part of it, contains a notice stating that it is
Martin@1
   391
governed by this License along with a term that is a further
Martin@1
   392
restriction, you may remove that term.  If a license document contains
Martin@1
   393
a further restriction but permits relicensing or conveying under this
Martin@1
   394
License, you may add to a covered work material governed by the terms
Martin@1
   395
of that license document, provided that the further restriction does
Martin@1
   396
not survive such relicensing or conveying.
Martin@1
   397
Martin@1
   398
  If you add terms to a covered work in accord with this section, you
Martin@1
   399
must place, in the relevant source files, a statement of the
Martin@1
   400
additional terms that apply to those files, or a notice indicating
Martin@1
   401
where to find the applicable terms.
Martin@1
   402
Martin@1
   403
  Additional terms, permissive or non-permissive, may be stated in the
Martin@1
   404
form of a separately written license, or stated as exceptions;
Martin@1
   405
the above requirements apply either way.
Martin@1
   406
Martin@1
   407
  8. Termination.
Martin@1
   408
Martin@1
   409
  You may not propagate or modify a covered work except as expressly
Martin@1
   410
provided under this License.  Any attempt otherwise to propagate or
Martin@1
   411
modify it is void, and will automatically terminate your rights under
Martin@1
   412
this License (including any patent licenses granted under the third
Martin@1
   413
paragraph of section 11).
Martin@1
   414
Martin@1
   415
  However, if you cease all violation of this License, then your
Martin@1
   416
license from a particular copyright holder is reinstated (a)
Martin@1
   417
provisionally, unless and until the copyright holder explicitly and
Martin@1
   418
finally terminates your license, and (b) permanently, if the copyright
Martin@1
   419
holder fails to notify you of the violation by some reasonable means
Martin@1
   420
prior to 60 days after the cessation.
Martin@1
   421
Martin@1
   422
  Moreover, your license from a particular copyright holder is
Martin@1
   423
reinstated permanently if the copyright holder notifies you of the
Martin@1
   424
violation by some reasonable means, this is the first time you have
Martin@1
   425
received notice of violation of this License (for any work) from that
Martin@1
   426
copyright holder, and you cure the violation prior to 30 days after
Martin@1
   427
your receipt of the notice.
Martin@1
   428
Martin@1
   429
  Termination of your rights under this section does not terminate the
Martin@1
   430
licenses of parties who have received copies or rights from you under
Martin@1
   431
this License.  If your rights have been terminated and not permanently
Martin@1
   432
reinstated, you do not qualify to receive new licenses for the same
Martin@1
   433
material under section 10.
Martin@1
   434
Martin@1
   435
  9. Acceptance Not Required for Having Copies.
Martin@1
   436
Martin@1
   437
  You are not required to accept this License in order to receive or
Martin@1
   438
run a copy of the Program.  Ancillary propagation of a covered work
Martin@1
   439
occurring solely as a consequence of using peer-to-peer transmission
Martin@1
   440
to receive a copy likewise does not require acceptance.  However,
Martin@1
   441
nothing other than this License grants you permission to propagate or
Martin@1
   442
modify any covered work.  These actions infringe copyright if you do
Martin@1
   443
not accept this License.  Therefore, by modifying or propagating a
Martin@1
   444
covered work, you indicate your acceptance of this License to do so.
Martin@1
   445
Martin@1
   446
  10. Automatic Licensing of Downstream Recipients.
Martin@1
   447
Martin@1
   448
  Each time you convey a covered work, the recipient automatically
Martin@1
   449
receives a license from the original licensors, to run, modify and
Martin@1
   450
propagate that work, subject to this License.  You are not responsible
Martin@1
   451
for enforcing compliance by third parties with this License.
Martin@1
   452
Martin@1
   453
  An "entity transaction" is a transaction transferring control of an
Martin@1
   454
organization, or substantially all assets of one, or subdividing an
Martin@1
   455
organization, or merging organizations.  If propagation of a covered
Martin@1
   456
work results from an entity transaction, each party to that
Martin@1
   457
transaction who receives a copy of the work also receives whatever
Martin@1
   458
licenses to the work the party's predecessor in interest had or could
Martin@1
   459
give under the previous paragraph, plus a right to possession of the
Martin@1
   460
Corresponding Source of the work from the predecessor in interest, if
Martin@1
   461
the predecessor has it or can get it with reasonable efforts.
Martin@1
   462
Martin@1
   463
  You may not impose any further restrictions on the exercise of the
Martin@1
   464
rights granted or affirmed under this License.  For example, you may
Martin@1
   465
not impose a license fee, royalty, or other charge for exercise of
Martin@1
   466
rights granted under this License, and you may not initiate litigation
Martin@1
   467
(including a cross-claim or counterclaim in a lawsuit) alleging that
Martin@1
   468
any patent claim is infringed by making, using, selling, offering for
Martin@1
   469
sale, or importing the Program or any portion of it.
Martin@1
   470
Martin@1
   471
  11. Patents.
Martin@1
   472
Martin@1
   473
  A "contributor" is a copyright holder who authorizes use under this
Martin@1
   474
License of the Program or a work on which the Program is based.  The
Martin@1
   475
work thus licensed is called the contributor's "contributor version".
Martin@1
   476
Martin@1
   477
  A contributor's "essential patent claims" are all patent claims
Martin@1
   478
owned or controlled by the contributor, whether already acquired or
Martin@1
   479
hereafter acquired, that would be infringed by some manner, permitted
Martin@1
   480
by this License, of making, using, or selling its contributor version,
Martin@1
   481
but do not include claims that would be infringed only as a
Martin@1
   482
consequence of further modification of the contributor version.  For
Martin@1
   483
purposes of this definition, "control" includes the right to grant
Martin@1
   484
patent sublicenses in a manner consistent with the requirements of
Martin@1
   485
this License.
Martin@1
   486
Martin@1
   487
  Each contributor grants you a non-exclusive, worldwide, royalty-free
Martin@1
   488
patent license under the contributor's essential patent claims, to
Martin@1
   489
make, use, sell, offer for sale, import and otherwise run, modify and
Martin@1
   490
propagate the contents of its contributor version.
Martin@1
   491
Martin@1
   492
  In the following three paragraphs, a "patent license" is any express
Martin@1
   493
agreement or commitment, however denominated, not to enforce a patent
Martin@1
   494
(such as an express permission to practice a patent or covenant not to
Martin@1
   495
sue for patent infringement).  To "grant" such a patent license to a
Martin@1
   496
party means to make such an agreement or commitment not to enforce a
Martin@1
   497
patent against the party.
Martin@1
   498
Martin@1
   499
  If you convey a covered work, knowingly relying on a patent license,
Martin@1
   500
and the Corresponding Source of the work is not available for anyone
Martin@1
   501
to copy, free of charge and under the terms of this License, through a
Martin@1
   502
publicly available network server or other readily accessible means,
Martin@1
   503
then you must either (1) cause the Corresponding Source to be so
Martin@1
   504
available, or (2) arrange to deprive yourself of the benefit of the
Martin@1
   505
patent license for this particular work, or (3) arrange, in a manner
Martin@1
   506
consistent with the requirements of this License, to extend the patent
Martin@1
   507
license to downstream recipients.  "Knowingly relying" means you have
Martin@1
   508
actual knowledge that, but for the patent license, your conveying the
Martin@1
   509
covered work in a country, or your recipient's use of the covered work
Martin@1
   510
in a country, would infringe one or more identifiable patents in that
Martin@1
   511
country that you have reason to believe are valid.
Martin@1
   512
Martin@1
   513
  If, pursuant to or in connection with a single transaction or
Martin@1
   514
arrangement, you convey, or propagate by procuring conveyance of, a
Martin@1
   515
covered work, and grant a patent license to some of the parties
Martin@1
   516
receiving the covered work authorizing them to use, propagate, modify
Martin@1
   517
or convey a specific copy of the covered work, then the patent license
Martin@1
   518
you grant is automatically extended to all recipients of the covered
Martin@1
   519
work and works based on it.
Martin@1
   520
Martin@1
   521
  A patent license is "discriminatory" if it does not include within
Martin@1
   522
the scope of its coverage, prohibits the exercise of, or is
Martin@1
   523
conditioned on the non-exercise of one or more of the rights that are
Martin@1
   524
specifically granted under this License.  You may not convey a covered
Martin@1
   525
work if you are a party to an arrangement with a third party that is
Martin@1
   526
in the business of distributing software, under which you make payment
Martin@1
   527
to the third party based on the extent of your activity of conveying
Martin@1
   528
the work, and under which the third party grants, to any of the
Martin@1
   529
parties who would receive the covered work from you, a discriminatory
Martin@1
   530
patent license (a) in connection with copies of the covered work
Martin@1
   531
conveyed by you (or copies made from those copies), or (b) primarily
Martin@1
   532
for and in connection with specific products or compilations that
Martin@1
   533
contain the covered work, unless you entered into that arrangement,
Martin@1
   534
or that patent license was granted, prior to 28 March 2007.
Martin@1
   535
Martin@1
   536
  Nothing in this License shall be construed as excluding or limiting
Martin@1
   537
any implied license or other defenses to infringement that may
Martin@1
   538
otherwise be available to you under applicable patent law.
Martin@1
   539
Martin@1
   540
  12. No Surrender of Others' Freedom.
Martin@1
   541
Martin@1
   542
  If conditions are imposed on you (whether by court order, agreement or
Martin@1
   543
otherwise) that contradict the conditions of this License, they do not
Martin@1
   544
excuse you from the conditions of this License.  If you cannot convey a
Martin@1
   545
covered work so as to satisfy simultaneously your obligations under this
Martin@1
   546
License and any other pertinent obligations, then as a consequence you may
Martin@1
   547
not convey it at all.  For example, if you agree to terms that obligate you
Martin@1
   548
to collect a royalty for further conveying from those to whom you convey
Martin@1
   549
the Program, the only way you could satisfy both those terms and this
Martin@1
   550
License would be to refrain entirely from conveying the Program.
Martin@1
   551
Martin@1
   552
  13. Use with the GNU Affero General Public License.
Martin@1
   553
Martin@1
   554
  Notwithstanding any other provision of this License, you have
Martin@1
   555
permission to link or combine any covered work with a work licensed
Martin@1
   556
under version 3 of the GNU Affero General Public License into a single
Martin@1
   557
combined work, and to convey the resulting work.  The terms of this
Martin@1
   558
License will continue to apply to the part which is the covered work,
Martin@1
   559
but the special requirements of the GNU Affero General Public License,
Martin@1
   560
section 13, concerning interaction through a network will apply to the
Martin@1
   561
combination as such.
Martin@1
   562
Martin@1
   563
  14. Revised Versions of this License.
Martin@1
   564
Martin@1
   565
  The Free Software Foundation may publish revised and/or new versions of
Martin@1
   566
the GNU General Public License from time to time.  Such new versions will
Martin@1
   567
be similar in spirit to the present version, but may differ in detail to
Martin@1
   568
address new problems or concerns.
Martin@1
   569
Martin@1
   570
  Each version is given a distinguishing version number.  If the
Martin@1
   571
Program specifies that a certain numbered version of the GNU General
Martin@1
   572
Public License "or any later version" applies to it, you have the
Martin@1
   573
option of following the terms and conditions either of that numbered
Martin@1
   574
version or of any later version published by the Free Software
Martin@1
   575
Foundation.  If the Program does not specify a version number of the
Martin@1
   576
GNU General Public License, you may choose any version ever published
Martin@1
   577
by the Free Software Foundation.
Martin@1
   578
Martin@1
   579
  If the Program specifies that a proxy can decide which future
Martin@1
   580
versions of the GNU General Public License can be used, that proxy's
Martin@1
   581
public statement of acceptance of a version permanently authorizes you
Martin@1
   582
to choose that version for the Program.
Martin@1
   583
Martin@1
   584
  Later license versions may give you additional or different
Martin@1
   585
permissions.  However, no additional obligations are imposed on any
Martin@1
   586
author or copyright holder as a result of your choosing to follow a
Martin@1
   587
later version.
Martin@1
   588
Martin@1
   589
  15. Disclaimer of Warranty.
Martin@1
   590
Martin@1
   591
  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
Martin@1
   592
APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
Martin@1
   593
HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
Martin@1
   594
OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
Martin@1
   595
THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
Martin@1
   596
PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
Martin@1
   597
IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
Martin@1
   598
ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
Martin@1
   599
Martin@1
   600
  16. Limitation of Liability.
Martin@1
   601
Martin@1
   602
  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
Martin@1
   603
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
Martin@1
   604
THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
Martin@1
   605
GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
Martin@1
   606
USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
Martin@1
   607
DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
Martin@1
   608
PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
Martin@1
   609
EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
Martin@1
   610
SUCH DAMAGES.
Martin@1
   611
Martin@1
   612
  17. Interpretation of Sections 15 and 16.
Martin@1
   613
Martin@1
   614
  If the disclaimer of warranty and limitation of liability provided
Martin@1
   615
above cannot be given local legal effect according to their terms,
Martin@1
   616
reviewing courts shall apply local law that most closely approximates
Martin@1
   617
an absolute waiver of all civil liability in connection with the
Martin@1
   618
Program, unless a warranty or assumption of liability accompanies a
Martin@1
   619
copy of the Program in return for a fee.
Martin@1
   620

                     END OF TERMS AND CONDITIONS

Martin@1
   623
            How to Apply These Terms to Your New Programs
Martin@1
   624
Martin@1
   625
  If you develop a new program, and you want it to be of the greatest
Martin@1
   626
possible use to the public, the best way to achieve this is to make it
Martin@1
   627
free software which everyone can redistribute and change under these terms.
Martin@1
   628
Martin@1
   629
  To do so, attach the following notices to the program.  It is safest
Martin@1
   630
to attach them to the start of each source file to most effectively
Martin@1
   631
state the exclusion of warranty; and each file should have at least
Martin@1
   632
the "copyright" line and a pointer to where the full notice is found.
Martin@1
   633
Martin@1
   634
    <one line to give the program's name and a brief idea of what it does.>

  If the program does terminal interaction, make it output a short
Martin@1
   653
notice like this when it starts in an interactive mode:
Martin@1
   654
Martin@1
   655
    <program>  Copyright (C) <year>  <name of author>

    under certain conditions; type `show c' for details.

The hypothetical commands `show w' and `show c' should show the appropriate

   661
parts of the General Public License.  Of course, your program's commands
Martin@1
   662
might be different; for a GUI interface, you would use an "about box".

  The GNU General Public License does not permit incorporating your program

may consider it more useful to permit linking proprietary applications with

the library.  If this is what you want to do, use the GNU Lesser General
