alpar@1
    27
  The GNU General Public License is a free, copyleft license for
alpar@1
    28
software and other kinds of works.
alpar@1
    29
alpar@1
    30
  The licenses for most software and other practical works are designed
alpar@1
    31
to take away your freedom to share and change the works.  By contrast,
alpar@1
    32
the GNU General Public License is intended to guarantee your freedom to
alpar@1
    33
share and change all versions of a program--to make sure it remains free
alpar@1
    34
software for all its users.  We, the Free Software Foundation, use the
alpar@1
    35
GNU General Public License for most of our software; it applies also to
alpar@1
    36
any other work released this way by its authors.  You can apply it to
alpar@1
    37
your programs, too.
alpar@1
    38
alpar@1
    39
  When we speak of free software, we are referring to freedom, not
alpar@1
    40
price.  Our General Public Licenses are designed to make sure that you
alpar@1
    41
have the freedom to distribute copies of free software (and charge for
alpar@1
    42
them if you wish), that you receive source code or can get it if you
alpar@1
    43
want it, that you can change the software or use pieces of it in new
alpar@1
    44
free programs, and that you know you can do these things.
alpar@1
    45
alpar@1
    46
  To protect your rights, we need to prevent others from denying you
alpar@1
    47
these rights or asking you to surrender the rights.  Therefore, you have
alpar@1
    48
certain responsibilities if you distribute copies of the software, or if
alpar@1
    49
you modify it: responsibilities to respect the freedom of others.
alpar@1
    50
alpar@1
    51
  For example, if you distribute copies of such a program, whether
alpar@1
    52
gratis or for a fee, you must pass on to the recipients the same
alpar@1
    53
freedoms that you received.  You must make sure that they, too, receive
alpar@1
    54
or can get the source code.  And you must show them these terms so they
alpar@1
    55
know their rights.
alpar@1
    56
alpar@1
    57
  Developers that use the GNU GPL protect your rights with two steps:
alpar@1
    58
(1) assert copyright on the software, and (2) offer you this License
alpar@1
    59
giving you legal permission to copy, distribute and/or modify it.
alpar@1
    60
alpar@1
    61
  For the developers' and authors' protection, the GPL clearly explains
alpar@1
    62
that there is no warranty for this free software.  For both users' and
alpar@1
    63
authors' sake, the GPL requires that modified versions be marked as
alpar@1
    64
changed, so that their problems will not be attributed erroneously to
alpar@1
    65
authors of previous versions.
alpar@1
    66
alpar@1
    67
  Some devices are designed to deny users access to install or run
alpar@1
    68
modified versions of the software inside them, although the manufacturer
alpar@1
    69
can do so.  This is fundamentally incompatible with the aim of
alpar@1
    70
protecting users' freedom to change the software.  The systematic
alpar@1
    71
pattern of such abuse occurs in the area of products for individuals to
alpar@1
    72
use, which is precisely where it is most unacceptable.  Therefore, we
alpar@1
    73
have designed this version of the GPL to prohibit the practice for those
alpar@1
    74
products.  If such problems arise substantially in other domains, we
alpar@1
    75
stand ready to extend this provision to those domains in future versions
alpar@1
    76
of the GPL, as needed to protect the freedom of users.
alpar@1
    77
alpar@1
    78
  Finally, every program is threatened constantly by software patents.
alpar@1
    79
States should not allow patents to restrict development and use of
alpar@1
    80
software on general-purpose computers, but in those that do, we wish to
alpar@1
    81
avoid the special danger that patents applied to a free program could
alpar@1
    82
make it effectively proprietary.  To prevent this, the GPL assures that
alpar@1
    83
patents cannot be used to render the program non-free.
alpar@1
    84
alpar@1
    85
  The precise terms and conditions for copying, distribution and
alpar@1
    86
modification follow.

\subsubsection*{0. Definitions.}
alpar@1
    91
alpar@1
    92
\noindent\indent
alpar@1
    93
  ``This License'' refers to version 3 of the GNU General Public
alpar@1
    94
License.
alpar@1
    95
alpar@1
    96
  ``Copyright'' also means copyright-like laws that apply to other kinds
alpar@1
    97
of works, such as semiconductor masks.
alpar@1
    98
alpar@1
    99
  ``The Program'' refers to any copyrightable work licensed under this
alpar@1
   100
License.  Each licensee is addressed as ``you''.  ``Licensees'' and
alpar@1
   101
``recipients'' may be individuals or organizations.
alpar@1
   102
alpar@1
   103
  To ``modify'' a work means to copy from or adapt all or part of the
alpar@1
   104
work in a fashion requiring copyright permission, other than the making
alpar@1
   105
of an exact copy.  The resulting work is called a ``modified version''
alpar@1
   106
of the earlier work or a work ``based on'' the earlier work.
alpar@1
   107
alpar@1
   108
  A ``covered work'' means either the unmodified Program or a work based
alpar@1
   109
on the Program.
alpar@1
   110
alpar@1
   111
  To ``propagate'' a work means to do anything with it that, without
alpar@1
   112
permission, would make you directly or secondarily liable for
alpar@1
   113
infringement under applicable copyright law, except executing it on a
alpar@1
   114
computer or modifying a private copy.  Propagation includes copying,
alpar@1
   115
distribution (with or without modification), making available to the
alpar@1
   116
public, and in some countries other activities as well.
alpar@1
   117
alpar@1
   118
  To ``convey'' a work means any kind of propagation that enables other
alpar@1
   119
parties to make or receive copies.  Mere interaction with a user through
alpar@1
   120
a computer network, with no transfer of a copy, is not conveying.
alpar@1
   121
alpar@1
   122
  An interactive user interface displays ``Appropriate Legal Notices''
alpar@1
   123
to the extent that it includes a convenient and prominently visible
alpar@1
   124
feature that (1) displays an appropriate copyright notice, and (2)
alpar@1
   125
tells the user that there is no warranty for the work (except to the
alpar@1
   126
extent that warranties are provided), that licensees may convey the
alpar@1
   127
work under this License, and how to view a copy of this License.  If
alpar@1
   128
the interface presents a list of user commands or options, such as a
alpar@1
   129
menu, a prominent item in the list meets this criterion.
alpar@1
   130
alpar@1
   131
\subsubsection*{1. Source Code.}
alpar@1
   132
alpar@1
   133
\noindent\indent
alpar@1
   134
  The ``source code'' for a work means the preferred form of the work
alpar@1
   135
for making modifications to it.  ``Object code'' means any non-source
alpar@1
   136
form of a work.
alpar@1
   137
alpar@1
   138
  A ``Standard Interface'' means an interface that either is an official
alpar@1
   139
standard defined by a recognized standards body, or, in the case of
alpar@1
   140
interfaces specified for a particular programming language, one that
alpar@1
   141
is widely used among developers working in that language.
alpar@1
   142
alpar@1
   143
  The ``System Libraries'' of an executable work include anything, other
alpar@1
   144
than the work as a whole, that (a) is included in the normal form of
alpar@1
   145
packaging a Major Component, but which is not part of that Major
alpar@1
   146
Component, and (b) serves only to enable use of the work with that
alpar@1
   147
Major Component, or to implement a Standard Interface for which an
alpar@1
   148
implementation is available to the public in source code form.  A
alpar@1
   149
``Major Component'', in this context, means a major essential component
alpar@1
   150
(kernel, window system, and so on) of the specific operating system
alpar@1
   151
(if any) on which the executable work runs, or a compiler used to
alpar@1
   152
produce the work, or an object code interpreter used to run it.
alpar@1
   153
alpar@1
   154
  The ``Corresponding Source'' for a work in object code form means all
alpar@1
   155
the source code needed to generate, install, and (for an executable
alpar@1
   156
work) run the object code and to modify the work, including scripts to
alpar@1
   157
control those activities.  However, it does not include the work's
alpar@1
   158
System Libraries, or general-purpose tools or generally available free
alpar@1
   159
programs which are used unmodified in performing those activities but
alpar@1
   160
which are not part of the work.  For example, Corresponding Source
alpar@1
   161
includes interface definition files associated with source files for
alpar@1
   162
the work, and the source code for shared libraries and dynamically
alpar@1
   163
linked subprograms that the work is specifically designed to require,
alpar@1
   164
such as by intimate data communication or control flow between those
alpar@1
   165
subprograms and other parts of the work.
alpar@1
   166
alpar@1
   167
  The Corresponding Source need not include anything that users
alpar@1
   168
can regenerate automatically from other parts of the Corresponding
alpar@1
   169
Source.
alpar@1
   170
alpar@1
   171
  The Corresponding Source for a work in source code form is that
alpar@1
   172
same work.
alpar@1
   173
alpar@1
   174
\subsubsection*{2. Basic Permissions.}
alpar@1
   175
alpar@1
   176
\noindent\indent
alpar@1
   177
  All rights granted under this License are granted for the term of
alpar@1
   178
copyright on the Program, and are irrevocable provided the stated
alpar@1
   179
conditions are met.  This License explicitly affirms your unlimited
alpar@1
   180
permission to run the unmodified Program.  The output from running a
alpar@1
   181
covered work is covered by this License only if the output, given its
alpar@1
   182
content, constitutes a covered work.  This License acknowledges your
alpar@1
   183
rights of fair use or other equivalent, as provided by copyright law.
alpar@1
   184
alpar@1
   185
  You may make, run and propagate covered works that you do not
alpar@1
   186
convey, without conditions so long as your license otherwise remains
alpar@1
   187
in force.  You may convey covered works to others for the sole purpose
alpar@1
   188
of having them make modifications exclusively for you, or provide you
alpar@1
   189
with facilities for running those works, provided that you comply with
alpar@1
   190
the terms of this License in conveying all material for which you do
alpar@1
   191
not control copyright.  Those thus making or running the covered works
alpar@1
   192
for you must do so exclusively on your behalf, under your direction
alpar@1
   193
and control, on terms that prohibit them from making any copies of
alpar@1
   194
your copyrighted material outside their relationship with you.
alpar@1
   195
alpar@1
   196
  Conveying under any other circumstances is permitted solely under
alpar@1
   197
the conditions stated below.  Sublicensing is not allowed; section 10
alpar@1
   198
makes it unnecessary.
alpar@1
   199
alpar@1
   200
\subsubsection*{3. Protecting Users' Legal Rights From
alpar@1
   201
Anti-Circumvention Law.}
alpar@1
   202
alpar@1
   203
\noindent\indent
alpar@1
   204
  No covered work shall be deemed part of an effective technological
alpar@1
   205
measure under any applicable law fulfilling obligations under article
alpar@1
   206
11 of the WIPO copyright treaty adopted on 20 December 1996, or
alpar@1
   207
similar laws prohibiting or restricting circumvention of such
alpar@1
   208
measures.
alpar@1
   209
alpar@1
   210
  When you convey a covered work, you waive any legal power to forbid
alpar@1
   211
circumvention of technological measures to the extent such circumvention
alpar@1
   212
is effected by exercising rights under this License with respect to
alpar@1
   213
the covered work, and you disclaim any intention to limit operation or
alpar@1
   214
modification of the work as a means of enforcing, against the work's
alpar@1
   215
users, your or third parties' legal rights to forbid circumvention of
alpar@1
   216
technological measures.
alpar@1
   217
alpar@1
   218
\subsubsection*{4. Conveying Verbatim Copies.}
alpar@1
   219
alpar@1
   220
\noindent\indent
alpar@1
   221
  You may convey verbatim copies of the Program's source code as you
alpar@1
   222
receive it, in any medium, provided that you conspicuously and
alpar@1
   223
appropriately publish on each copy an appropriate copyright notice;
alpar@1
   224
keep intact all notices stating that this License and any
alpar@1
   225
non-permissive terms added in accord with section 7 apply to the code;
alpar@1
   226
keep intact all notices of the absence of any warranty; and give all
alpar@1
   227
recipients a copy of this License along with the Program.
alpar@1
   228
alpar@1
   229
  You may charge any price or no price for each copy that you convey,
alpar@1
   230
and you may offer support or warranty protection for a fee.
alpar@1
   231
alpar@1
   232
\subsubsection*{5. Conveying Modified Source Versions.}
alpar@1
   233
alpar@1
   234
  You may convey a work based on the Program, or the modifications to
alpar@1
   235
produce it from the Program, in the form of source code under the
alpar@1
   236
terms of section 4, provided that you also meet all of these conditions:
alpar@1
   237
alpar@1
   238
    a) The work must carry prominent notices stating that you modified
alpar@1
   239
    it, and giving a relevant date.
alpar@1
   240
alpar@1
   241
    b) The work must carry prominent notices stating that it is
alpar@1
   242
    released under this License and any conditions added under section
alpar@1
   243
    7.  This requirement modifies the requirement in section 4 to
alpar@1
   244
    ``keep intact all notices''.
alpar@1
   245
alpar@1
   246
    c) You must license the entire work, as a whole, under this
alpar@1
   247
    License to anyone who comes into possession of a copy.  This
alpar@1
   248
    License will therefore apply, along with any applicable section 7
alpar@1
   249
    additional terms, to the whole of the work, and all its parts,
alpar@1
   250
    regardless of how they are packaged.  This License gives no
alpar@1
   251
    permission to license the work in any other way, but it does not
alpar@1
   252
    invalidate such permission if you have separately received it.
alpar@1
   253
alpar@1
   254
    d) If the work has interactive user interfaces, each must display
alpar@1
   255
    Appropriate Legal Notices; however, if the Program has interactive
alpar@1
   256
    interfaces that do not display Appropriate Legal Notices, your
alpar@1
   257
    work need not make them do so.
alpar@1
   258
alpar@1
   259
  A compilation of a covered work with other separate and independent
alpar@1
   260
works, which are not by their nature extensions of the covered work,
alpar@1
   261
and which are not combined with it such as to form a larger program,
alpar@1
   262
in or on a volume of a storage or distribution medium, is called an
alpar@1
   263
``aggregate'' if the compilation and its resulting copyright are not
alpar@1
   264
used to limit the access or legal rights of the compilation's users
alpar@1
   265
beyond what the individual works permit.  Inclusion of a covered work
alpar@1
   266
in an aggregate does not cause this License to apply to the other
alpar@1
   267
parts of the aggregate.
alpar@1
   268
alpar@1
   269
\subsubsection*{6. Conveying Non-Source Forms.}
alpar@1
   270
alpar@1
   271
  You may convey a covered work in object code form under the terms
alpar@1
   272
of sections 4 and 5, provided that you also convey the
alpar@1
   273
machine-readable Corresponding Source under the terms of this License,
alpar@1
   274
in one of these ways:
alpar@1
   275
alpar@1
   276
    a) Convey the object code in, or embodied in, a physical product
alpar@1
   277
    (including a physical distribution medium), accompanied by the
alpar@1
   278
    Corresponding Source fixed on a durable physical medium
alpar@1
   279
    customarily used for software interchange.
alpar@1
   280
alpar@1
   281
    b) Convey the object code in, or embodied in, a physical product
alpar@1
   282
    (including a physical distribution medium), accompanied by a
alpar@1
   283
    written offer, valid for at least three years and valid for as
alpar@1
   284
    long as you offer spare parts or customer support for that product
alpar@1
   285
    model, to give anyone who possesses the object code either (1) a
alpar@1
   286
    copy of the Corresponding Source for all the software in the
alpar@1
   287
    product that is covered by this License, on a durable physical
alpar@1
   288
    medium customarily used for software interchange, for a price no
alpar@1
   289
    more than your reasonable cost of physically performing this
alpar@1
   290
    conveying of source, or (2) access to copy the
alpar@1
   291
    Corresponding Source from a network server at no charge.
alpar@1
   292
alpar@1
   293
    c) Convey individual copies of the object code with a copy of the
alpar@1
   294
    written offer to provide the Corresponding Source.  This
alpar@1
   295
    alternative is allowed only occasionally and noncommercially, and
alpar@1
   296
    only if you received the object code with such an offer, in accord
alpar@1
   297
    with subsection 6b.
alpar@1
   298
alpar@1
   299
    d) Convey the object code by offering access from a designated
alpar@1
   300
    place (gratis or for a charge), and offer equivalent access to the
alpar@1
   301
    Corresponding Source in the same way through the same place at no
alpar@1
   302
    further charge.  You need not require recipients to copy the
alpar@1
   303
    Corresponding Source along with the object code.  If the place to
alpar@1
   304
    copy the object code is a network server, the Corresponding Source
alpar@1
   305
    may be on a different server (operated by you or a third party)
alpar@1
   306
    that supports equivalent copying facilities, provided you maintain
alpar@1
   307
    clear directions next to the object code saying where to find the
alpar@1
   308
    Corresponding Source.  Regardless of what server hosts the
alpar@1
   309
    Corresponding Source, you remain obligated to ensure that it is
alpar@1
   310
    available for as long as needed to satisfy these requirements.
alpar@1
   311
alpar@1
   312
    e) Convey the object code using peer-to-peer transmission, provided
alpar@1
   313
    you inform other peers where the object code and Corresponding
alpar@1
   314
    Source of the work are being offered to the general public at no
alpar@1
   315
    charge under subsection 6d.
alpar@1
   316
alpar@1
   317
  A separable portion of the object code, whose source code is excluded
alpar@1
   318
from the Corresponding Source as a System Library, need not be
alpar@1
   319
included in conveying the object code work.
alpar@1
   320
alpar@1
   321
  A ``User Product'' is either (1) a ``consumer product'', which means
alpar@1
   322
any tangible personal property which is normally used for personal,
alpar@1
   323
family, or household purposes, or (2) anything designed or sold for
alpar@1
   324
incorporation into a dwelling.  In determining whether a product is a
alpar@1
   325
consumer product, doubtful cases shall be resolved in favor of coverage.
alpar@1
   326
For a particular product received by a particular user, ``normally
alpar@1
   327
used'' refers to a typical or common use of that class of product,
alpar@1
   328
regardless of the status of the particular user or of the way in which
alpar@1
   329
the particular user actually uses, or expects or is expected to use, the
alpar@1
   330
product.  A product is a consumer product regardless of whether the
alpar@1
   331
product has substantial commercial, industrial or non-consumer uses,
alpar@1
   332
unless such uses represent the only significant mode of use of the
alpar@1
   333
product.
alpar@1
   334
alpar@1
   335
  ``Installation Information'' for a User Product means any methods,
alpar@1
   336
procedures, authorization keys, or other information required to install
alpar@1
   337
and execute modified versions of a covered work in that User Product
alpar@1
   338
from a modified version of its Corresponding Source.  The information
alpar@1
   339
must suffice to ensure that the continued functioning of the modified
alpar@1
   340
object code is in no case prevented or interfered with solely because
alpar@1
   341
modification has been made.
alpar@1
   342
alpar@1
   343
  If you convey an object code work under this section in, or with, or
alpar@1
   344
specifically for use in, a User Product, and the conveying occurs as
alpar@1
   345
part of a transaction in which the right of possession and use of the
alpar@1
   346
User Product is transferred to the recipient in perpetuity or for a
alpar@1
   347
fixed term (regardless of how the transaction is characterized), the
alpar@1
   348
Corresponding Source conveyed under this section must be accompanied
alpar@1
   349
by the Installation Information.  But this requirement does not apply
alpar@1
   350
if neither you nor any third party retains the ability to install
alpar@1
   351
modified object code on the User Product (for example, the work has
alpar@1
   352
been installed in ROM).
alpar@1
   353
alpar@1
   354
  The requirement to provide Installation Information does not include a
alpar@1
   355
requirement to continue to provide support service, warranty, or updates
alpar@1
   356
for a work that has been modified or installed by the recipient, or for
alpar@1
   357
the User Product in which it has been modified or installed.  Access to
alpar@1
   358
a network may be denied when the modification itself materially and
alpar@1
   359
adversely affects the operation of the network or violates the rules and
alpar@1
   360
protocols for communication across the network.
alpar@1
   361
alpar@1
   362
  Corresponding Source conveyed, and Installation Information provided,
alpar@1
   363
in accord with this section must be in a format that is publicly
alpar@1
   364
documented (and with an implementation available to the public in
alpar@1
   365
source code form), and must require no special password or key for
alpar@1
   366
unpacking, reading or copying.
alpar@1

\subsubsection*{7. Additional Terms.}
alpar@1
   369
alpar@1
   370
\noindent\indent
alpar@1
   371
  ``Additional permissions'' are terms that supplement the terms of this
alpar@1
   372
License by making exceptions from one or more of its conditions.
alpar@1
   373
Additional permissions that are applicable to the entire Program shall
alpar@1
   374
be treated as though they were included in this License, to the extent
alpar@1
   375
that they are valid under applicable law.  If additional permissions
alpar@1
   376
apply only to part of the Program, that part may be used separately
alpar@1
   377
under those permissions, but the entire Program remains governed by
alpar@1
   378
this License without regard to the additional permissions.
alpar@1
   379
alpar@1
   380
  When you convey a copy of a covered work, you may at your option
alpar@1
   381
remove any additional permissions from that copy, or from any part of
alpar@1
   382
it.  (Additional permissions may be written to require their own
alpar@1
   383
removal in certain cases when you modify the work.)  You may place
alpar@1
   384
additional permissions on material, added by you to a covered work,
alpar@1
   385
for which you have or can give appropriate copyright permission.
alpar@1
   386
alpar@1
   387
  Notwithstanding any other provision of this License, for material you
alpar@1
   388
add to a covered work, you may (if authorized by the copyright holders
alpar@1
   389
of that material) supplement the terms of this License with terms:
alpar@1
   390
alpar@1
   391
    a) Disclaiming warranty or limiting liability differently from the
alpar@1
   392
    terms of sections 15 and 16 of this License; or
alpar@1
   393
alpar@1
   394
    b) Requiring preservation of specified reasonable legal notices or
alpar@1
   395
    author attributions in that material or in the Appropriate Legal
alpar@1
   396
    Notices displayed by works containing it; or
alpar@1
   397
alpar@1
   398
    c) Prohibiting misrepresentation of the origin of that material, or
alpar@1
   399
    requiring that modified versions of such material be marked in
alpar@1
   400
    reasonable ways as different from the original version; or
alpar@1
   401
alpar@1
   402
    d) Limiting the use for publicity purposes of names of licensors or
alpar@1
   403
    authors of the material; or
alpar@1
   404
alpar@1
   405
    e) Declining to grant rights under trademark law for use of some
alpar@1
   406
    trade names, trademarks, or service marks; or
alpar@1
   407
alpar@1
   408
    f) Requiring indemnification of licensors and authors of that
alpar@1
   409
    material by anyone who conveys the material (or modified versions of
alpar@1
   410
    it) with contractual assumptions of liability to the recipient, for
alpar@1
   411
    any liability that these contractual assumptions directly impose on
alpar@1
   412
    those licensors and authors.
alpar@1
   413
alpar@1
   414
  All other non-permissive additional terms are considered ``further
alpar@1
   415
restrictions'' within the meaning of section 10.  If the Program as you
alpar@1
   416
received it, or any part of it, contains a notice stating that it is
alpar@1
   417
governed by this License along with a term that is a further
alpar@1
   418
restriction, you may remove that term.  If a license document contains
alpar@1
   419
a further restriction but permits relicensing or conveying under this
alpar@1
   420
License, you may add to a covered work material governed by the terms
alpar@1
   421
of that license document, provided that the further restriction does
alpar@1
   422
not survive such relicensing or conveying.
alpar@1
   423
alpar@1
   424
  If you add terms to a covered work in accord with this section, you
alpar@1
   425
must place, in the relevant source files, a statement of the
alpar@1
   426
additional terms that apply to those files, or a notice indicating
alpar@1
   427
where to find the applicable terms.
alpar@1
   428
alpar@1
   429
  Additional terms, permissive or non-permissive, may be stated in the
alpar@1
   430
form of a separately written license, or stated as exceptions;
alpar@1
   431
the above requirements apply either way.
alpar@1
   432
alpar@1
   433
\subsubsection*{8. Termination.}
alpar@1
   434
alpar@1
   435
\noindent\indent
alpar@1
   436
  You may not propagate or modify a covered work except as expressly
alpar@1
   437
provided under this License.  Any attempt otherwise to propagate or
alpar@1
   438
modify it is void, and will automatically terminate your rights under
alpar@1
   439
this License (including any patent licenses granted under the third
alpar@1
   440
paragraph of section 11).
alpar@1
   441
alpar@1
   442
  However, if you cease all violation of this License, then your
alpar@1
   443
license from a particular copyright holder is reinstated (a)
alpar@1
   444
provisionally, unless and until the copyright holder explicitly and
alpar@1
   445
finally terminates your license, and (b) permanently, if the copyright
alpar@1
   446
holder fails to notify you of the violation by some reasonable means
alpar@1
   447
prior to 60 days after the cessation.
alpar@1
   448
alpar@1
   449
  Moreover, your license from a particular copyright holder is
alpar@1
   450
reinstated permanently if the copyright holder notifies you of the
alpar@1
   451
violation by some reasonable means, this is the first time you have
alpar@1
   452
received notice of violation of this License (for any work) from that
alpar@1
   453
copyright holder, and you cure the violation prior to 30 days after
alpar@1
   454
your receipt of the notice.
alpar@1
   455
alpar@1
   456
  Termination of your rights under this section does not terminate the
alpar@1
   457
licenses of parties who have received copies or rights from you under
alpar@1
   458
this License.  If your rights have been terminated and not permanently
alpar@1
   459
reinstated, you do not qualify to receive new licenses for the same
alpar@1
   460
material under section 10.
alpar@1
   461
alpar@1
   462
\subsubsection*{9. Acceptance Not Required for Having Copies.}
alpar@1
   463
alpar@1
   464
\noindent\indent
alpar@1
   465
  You are not required to accept this License in order to receive or
alpar@1
   466
run a copy of the Program.  Ancillary propagation of a covered work
alpar@1
   467
occurring solely as a consequence of using peer-to-peer transmission
alpar@1
   468
to receive a copy likewise does not require acceptance.  However,
alpar@1
   469
nothing other than this License grants you permission to propagate or
alpar@1
   470
modify any covered work.  These actions infringe copyright if you do
alpar@1
   471
not accept this License.  Therefore, by modifying or propagating a
alpar@1
   472
covered work, you indicate your acceptance of this License to do so.
alpar@1
   473
alpar@1
   474
\subsubsection*{10. Automatic Licensing of Downstream Recipients.}
alpar@1
   475
alpar@1
   476
\noindent\indent
alpar@1
   477
  Each time you convey a covered work, the recipient automatically
alpar@1
   478
receives a license from the original licensors, to run, modify and
alpar@1
   479
propagate that work, subject to this License.  You are not responsible
alpar@1
   480
for enforcing compliance by third parties with this License.
alpar@1
   481
alpar@1
   482
  An ``entity transaction'' is a transaction transferring control of an
alpar@1
   483
organization, or substantially all assets of one, or subdividing an
alpar@1
   484
organization, or merging organizations.  If propagation of a covered
alpar@1
   485
work results from an entity transaction, each party to that
alpar@1
   486
transaction who receives a copy of the work also receives whatever
alpar@1
   487
licenses to the work the party's predecessor in interest had or could
alpar@1
   488
give under the previous paragraph, plus a right to possession of the
alpar@1
   489
Corresponding Source of the work from the predecessor in interest, if
alpar@1
   490
the predecessor has it or can get it with reasonable efforts.
alpar@1
   491
alpar@1
   492
  You may not impose any further restrictions on the exercise of the
alpar@1
   493
rights granted or affirmed under this License.  For example, you may
alpar@1
   494
not impose a license fee, royalty, or other charge for exercise of
alpar@1
   495
rights granted under this License, and you may not initiate litigation
alpar@1
   496
(including a cross-claim or counterclaim in a lawsuit) alleging that
alpar@1
   497
any patent claim is infringed by making, using, selling, offering for
alpar@1
   498
sale, or importing the Program or any portion of it.
alpar@1

\subsubsection*{11. Patents.}
alpar@1
   501
alpar@1
   502
\noindent\indent
alpar@1
   503
  A ``contributor'' is a copyright holder who authorizes use under this
alpar@1
   504
License of the Program or a work on which the Program is based.  The
alpar@1
   505
work thus licensed is called the contributor's ``contributor version''.
alpar@1
   506
alpar@1
   507
  A contributor's ``essential patent claims'' are all patent claims
alpar@1
   508
owned or controlled by the contributor, whether already acquired or
alpar@1
   509
hereafter acquired, that would be infringed by some manner, permitted
alpar@1
   510
by this License, of making, using, or selling its contributor version,
alpar@1
   511
but do not include claims that would be infringed only as a
alpar@1
   512
consequence of further modification of the contributor version.  For
alpar@1
   513
purposes of this definition, ``control'' includes the right to grant
alpar@1
   514
patent sublicenses in a manner consistent with the requirements of
alpar@1
   515
this License.
alpar@1
   516
alpar@1
   517
  Each contributor grants you a non-exclusive, worldwide, royalty-free
alpar@1
   518
patent license under the contributor's essential patent claims, to
alpar@1
   519
make, use, sell, offer for sale, import and otherwise run, modify and
alpar@1
   520
propagate the contents of its contributor version.
alpar@1
   521
alpar@1
   522
  In the following three paragraphs, a ``patent license'' is any express
alpar@1
   523
agreement or commitment, however denominated, not to enforce a patent
alpar@1
   524
(such as an express permission to practice a patent or covenant not to
alpar@1
   525
sue for patent infringement).  To ``grant'' such a patent license to a
alpar@1
   526
party means to make such an agreement or commitment not to enforce a
alpar@1
   527
patent against the party.
alpar@1
   528
alpar@1
   529
  If you convey a covered work, knowingly relying on a patent license,
alpar@1
   530
and the Corresponding Source of the work is not available for anyone
alpar@1
   531
to copy, free of charge and under the terms of this License, through a
alpar@1
   532
publicly available network server or other readily accessible means,
alpar@1
   533
then you must either (1) cause the Corresponding Source to be so
alpar@1
   534
available, or (2) arrange to deprive yourself of the benefit of the
alpar@1
   535
patent license for this particular work, or (3) arrange, in a manner
alpar@1
   536
consistent with the requirements of this License, to extend the patent
alpar@1
   537
license to downstream recipients.  ``Knowingly relying'' means you have
alpar@1
   538
actual knowledge that, but for the patent license, your conveying the
alpar@1
   539
covered work in a country, or your recipient's use of the covered work
alpar@1
   540
in a country, would infringe one or more identifiable patents in that
alpar@1
   541
country that you have reason to believe are valid.
alpar@1
   542
alpar@1
   543
  If, pursuant to or in connection with a single transaction or
alpar@1
   544
arrangement, you convey, or propagate by procuring conveyance of, a
alpar@1
   545
covered work, and grant a patent license to some of the parties
alpar@1
   546
receiving the covered work authorizing them to use, propagate, modify
alpar@1
   547
or convey a specific copy of the covered work, then the patent license
alpar@1
   548
you grant is automatically extended to all recipients of the covered
alpar@1
   549
work and works based on it.
alpar@1
   550
alpar@1
   551
  A patent license is ``discriminatory'' if it does not include within
alpar@1
   552
the scope of its coverage, prohibits the exercise of, or is
alpar@1
   553
conditioned on the non-exercise of one or more of the rights that are
alpar@1
   554
specifically granted under this License.  You may not convey a covered
alpar@1
   555
work if you are a party to an arrangement with a third party that is
alpar@1
   556
in the business of distributing software, under which you make payment
alpar@1
   557
to the third party based on the extent of your activity of conveying
alpar@1
   558
the work, and under which the third party grants, to any of the
alpar@1
   559
parties who would receive the covered work from you, a discriminatory
alpar@1
   560
patent license (a) in connection with copies of the covered work
alpar@1
   561
conveyed by you (or copies made from those copies), or (b) primarily
alpar@1
   562
for and in connection with specific products or compilations that
alpar@1
   563
contain the covered work, unless you entered into that arrangement,
alpar@1
   564
or that patent license was granted, prior to 28 March 2007.
alpar@1
   565
alpar@1
   566
  Nothing in this License shall be construed as excluding or limiting
alpar@1
   567
any implied license or other defenses to infringement that may
alpar@1
   568
otherwise be available to you under applicable patent law.
alpar@1

\subsubsection*{12. No Surrender of Others' Freedom.}
alpar@1
   571
alpar@1
   572
\noindent\indent
alpar@1
   573
  If conditions are imposed on you (whether by court order, agreement or
alpar@1
   574
otherwise) that contradict the conditions of this License, they do not
alpar@1
   575
excuse you from the conditions of this License.  If you cannot convey a
alpar@1
   576
covered work so as to satisfy simultaneously your obligations under this
alpar@1
   577
License and any other pertinent obligations, then as a consequence you
alpar@1
   578
may not convey it at all.  For example, if you agree to terms that
alpar@1
   579
obligate you to collect a royalty for further conveying from those to
alpar@1
   580
whom you convey the Program, the only way you could satisfy both those
alpar@1
   581
terms and this License would be to refrain entirely from conveying the
alpar@1
   582
Program.
alpar@1

\subsubsection*{13. Use with the GNU Affero General Public License.}
alpar@1
   585
alpar@1
   586
\noindent\indent
alpar@1
   587
  Notwithstanding any other provision of this License, you have
alpar@1
   588
permission to link or combine any covered work with a work licensed
alpar@1
   589
under version 3 of the GNU Affero General Public License into a single
alpar@1
   590
combined work, and to convey the resulting work.  The terms of this
alpar@1
   591
License will continue to apply to the part which is the covered work,
alpar@1
   592
but the special requirements of the GNU Affero General Public License,
alpar@1
   593
section 13, concerning interaction through a network will apply to the
alpar@1
   594
combination as such.
alpar@1

\subsubsection*{14. Revised Versions of this License.}
alpar@1
   597
alpar@1
   598
\noindent\indent
alpar@1
   599
  The Free Software Foundation may publish revised and/or new versions
alpar@1
   600
of the GNU General Public License from time to time.  Such new versions
alpar@1
   601
will be similar in spirit to the present version, but may differ in
alpar@1
   602
detail to address new problems or concerns.
alpar@1
   603
alpar@1
   604
  Each version is given a distinguishing version number.  If the
alpar@1
   605
Program specifies that a certain numbered version of the GNU General
alpar@1
   606
Public License ``or any later version'' applies to it, you have the
alpar@1
   607
option of following the terms and conditions either of that numbered
alpar@1
   608
version or of any later version published by the Free Software
alpar@1
   609
Foundation.  If the Program does not specify a version number of the
alpar@1
   610
GNU General Public License, you may choose any version ever published
alpar@1
   611
by the Free Software Foundation.
alpar@1
   612
alpar@1
   613
  If the Program specifies that a proxy can decide which future
alpar@1
   614
versions of the GNU General Public License can be used, that proxy's
alpar@1
   615
public statement of acceptance of a version permanently authorizes you
alpar@1
   616
to choose that version for the Program.
alpar@1
   617
alpar@1
   618
  Later license versions may give you additional or different
alpar@1
   619
permissions.  However, no additional obligations are imposed on any
alpar@1
   620
author or copyright holder as a result of your choosing to follow a
alpar@1
   621
later version.

\section*{How to Apply These Terms to Your New Programs}
alpar@1
   663
alpar@1
   664
\noindent\indent
alpar@1
   665
  If you develop a new program, and you want it to be of the greatest
alpar@1
   666
possible use to the public, the best way to achieve this is to make it
alpar@1
   667
free software which everyone can redistribute and change under these
alpar@1
   668
terms.
alpar@1
   669
alpar@1
   670
  To do so, attach the following notices to the program.  It is safest
alpar@1
   671
to attach them to the start of each source file to most effectively
alpar@1
   672
state the exclusion of warranty; and each file should have at least
alpar@1
   673
the ``copyright'' line and a pointer to where the full notice is found.
alpar@1
   674
alpar@1
   675
\begin{verbatim}
alpar@1
   676
<one line to give the program's name and a brief idea of what it does.>

alpar@1
   685
but WITHOUT ANY WARRANTY; without even the implied warranty of
alpar@1
   686

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

\end{verbatim}
alpar@1
   692
alpar@1
   693
\noindent
alpar@1
   694
Also add information on how to contact you by electronic and paper mail.
alpar@1
   695
alpar@1
   696
  If the program does terminal interaction, make it output a short
alpar@1
   697
notice like this when it starts in an interactive mode:
alpar@1
   698
alpar@1
   699
\begin{verbatim}
alpar@1
   700
<program>  Copyright (C) <year>  <name of author>
alpar@1
   701
This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
alpar@1
   702
This is free software, and you are welcome to redistribute it
alpar@1
   703
under certain conditions; type `show c' for details.
alpar@1
   704
\end{verbatim}
alpar@1
   705
alpar@1
   706
\noindent
alpar@1
   707
The hypothetical commands `show w' and `show c' should show the
alpar@1
   708
appropriate parts of the General Public License.  Of course, your
alpar@1
   709
program's commands might be different; for a GUI interface, you would
alpar@1
   710
use an ``about box''.
alpar@1
   711
alpar@1
   712
  You should also get your employer (if you work as a programmer) or
alpar@1
   713
school, if any, to sign a ``copyright disclaimer'' for the program, if
alpar@1
   714
necessary. For more information on this, and how to apply and follow the
alpar@1
   715
GNU GPL, see \verb|<http://www.gnu.org/licenses/>|.
alpar@1
   716
alpar@1
   717
  The GNU General Public License does not permit incorporating your
alpar@1
   718
program into proprietary programs.  If your program is a subroutine
alpar@1
   719
library, you may consider it more useful to permit linking proprietary
alpar@1
   720
applications with the library.  If this is what you want to do, use the
alpar@1
   721
GNU Lesser General Public License instead of this License.  But first,
alpar@1
   722
please read \verb|<http://www.gnu.org/philosophy/why-not-lgpl.html>|.
