 Everyone is permitted to copy and distribute verbatim copies
damiano@228
     6
 of this license document, but changing it is not allowed.

                            Preamble
damiano@228
     9
damiano@228
    10
  The GNU General Public License is a free, copyleft license for
damiano@228
    11
software and other kinds of works.
damiano@228
    12
damiano@228
    13
  The licenses for most software and other practical works are designed
damiano@228
    14
to take away your freedom to share and change the works.  By contrast,
damiano@228
    15
the GNU General Public License is intended to guarantee your freedom to
damiano@228
    16
share and change all versions of a program--to make sure it remains free
damiano@228
    17
software for all its users.  We, the Free Software Foundation, use the
damiano@228
    18
GNU General Public License for most of our software; it applies also to
damiano@228
    19
any other work released this way by its authors.  You can apply it to
damiano@228
    20
your programs, too.
damiano@228
    21
damiano@228
    22
  When we speak of free software, we are referring to freedom, not
damiano@228
    23
price.  Our General Public Licenses are designed to make sure that you
damiano@228
    24
have the freedom to distribute copies of free software (and charge for
damiano@228
    25
them if you wish), that you receive source code or can get it if you
damiano@228
    26
want it, that you can change the software or use pieces of it in new
damiano@228
    27
free programs, and that you know you can do these things.
damiano@228
    28
damiano@228
    29
  To protect your rights, we need to prevent others from denying you
damiano@228
    30
these rights or asking you to surrender the rights.  Therefore, you have
damiano@228
    31
certain responsibilities if you distribute copies of the software, or if
damiano@228
    32
you modify it: responsibilities to respect the freedom of others.
damiano@228
    33
damiano@228
    34
  For example, if you distribute copies of such a program, whether
damiano@228
    35
gratis or for a fee, you must pass on to the recipients the same
damiano@228
    36
freedoms that you received.  You must make sure that they, too, receive
damiano@228
    37
or can get the source code.  And you must show them these terms so they
damiano@228
    38
know their rights.
damiano@228
    39
damiano@228
    40
  Developers that use the GNU GPL protect your rights with two steps:
damiano@228
    41
(1) assert copyright on the software, and (2) offer you this License
damiano@228
    42
giving you legal permission to copy, distribute and/or modify it.
damiano@228
    43
damiano@228
    44
  For the developers' and authors' protection, the GPL clearly explains
damiano@228
    45
that there is no warranty for this free software.  For both users' and
damiano@228
    46
authors' sake, the GPL requires that modified versions be marked as
damiano@228
    47
changed, so that their problems will not be attributed erroneously to
damiano@228
    48
authors of previous versions.
damiano@228
    49
damiano@228
    50
  Some devices are designed to deny users access to install or run
damiano@228
    51
modified versions of the software inside them, although the manufacturer
damiano@228
    52
can do so.  This is fundamentally incompatible with the aim of
damiano@228
    53
protecting users' freedom to change the software.  The systematic
damiano@228
    54
pattern of such abuse occurs in the area of products for individuals to
damiano@228
    55
use, which is precisely where it is most unacceptable.  Therefore, we
damiano@228
    56
have designed this version of the GPL to prohibit the practice for those
damiano@228
    57
products.  If such problems arise substantially in other domains, we
damiano@228
    58
stand ready to extend this provision to those domains in future versions
damiano@228
    59
of the GPL, as needed to protect the freedom of users.
damiano@228
    60
damiano@228
    61
  Finally, every program is threatened constantly by software patents.
damiano@228
    62
States should not allow patents to restrict development and use of
damiano@228
    63
software on general-purpose computers, but in those that do, we wish to
damiano@228
    64
avoid the special danger that patents applied to a free program could
damiano@228
    65
make it effectively proprietary.  To prevent this, the GPL assures that
damiano@228
    66
patents cannot be used to render the program non-free.
damiano@228
    67
damiano@228
    68
  The precise terms and conditions for copying, distribution and
damiano@228
    69
modification follow.

                       TERMS AND CONDITIONS

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

  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
damiano@228
   592
APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
damiano@228
   593
HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
damiano@228

   595
THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR

   601
damiano@228
   602
  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
damiano@228
   603
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
damiano@228
   604
THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
damiano@228
   605
GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE

USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
damiano@228
   607
DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
damiano@228
   608
PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),

damiano@228
   610
SUCH DAMAGES.

damiano@228
   613
damiano@228
   614
  If the disclaimer of warranty and limitation of liability provided
damiano@228
   615
above cannot be given local legal effect according to their terms,
damiano@228
   616
reviewing courts shall apply local law that most closely approximates
damiano@228
   617
an absolute waiver of all civil liability in connection with the
damiano@228
   618
Program, unless a warranty or assumption of liability accompanies a
damiano@228
   619
copy of the Program in return for a fee.

            How to Apply These Terms to Your New Programs
damiano@228
   624
damiano@228
   625
  If you develop a new program, and you want it to be of the greatest
damiano@228
   626
possible use to the public, the best way to achieve this is to make it
damiano@228
   627
free software which everyone can redistribute and change under these terms.
damiano@228
   628
damiano@228
   629
  To do so, attach the following notices to the program.  It is safest
damiano@228
   630
to attach them to the start of each source file to most effectively
damiano@228
   631
state the exclusion of warranty; and each file should have at least
damiano@228
   632
the "copyright" line and a pointer to where the full notice is found.
damiano@228
   633
damiano@228
   634
    <one line to give the program's name and a brief idea of what it does.>

    You should have received a copy of the GNU General Public License

Also add information on how to contact you by electronic and paper mail.
damiano@228
   651
damiano@228
   652
  If the program does terminal interaction, make it output a short
damiano@228
   653
notice like this when it starts in an interactive mode:
damiano@228
   654
damiano@228
   655
    <program>  Copyright (C) <year>  <name of author>
damiano@228
   656
    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
damiano@228
   657
    This is free software, and you are welcome to redistribute it
damiano@228
   658
    under certain conditions; type `show c' for details.
damiano@228
   659
damiano@228
   660
The hypothetical commands `show w' and `show c' should show the appropriate
damiano@228
   661
parts of the General Public License.  Of course, your program's commands
damiano@228
   662
might be different; for a GUI interface, you would use an "about box".
damiano@228
   663
damiano@228
   664
  You should also get your employer (if you work as a programmer) or school,
damiano@228
   665
if any, to sign a "copyright disclaimer" for the program, if necessary.
