<p>Copyright © 2007 Free Software Foundation, Inc.

 &lt;<a href="http://fsf.org/">http://fsf.org/</a>&gt;</p><p>

15

 Everyone is permitted to copy and distribute verbatim copies

16

 of this license document, but changing it is not allowed.</p>

17

18

<h3><a name="preamble"></a>Preamble</h3>

19

20

<p>The GNU General Public License is a free, copyleft license for

21

software and other kinds of works.</p>

22

23

<p>The licenses for most software and other practical works are designed

24

to take away your freedom to share and change the works.  By contrast,

25

the GNU General Public License is intended to guarantee your freedom to

26

share and change all versions of a program--to make sure it remains free

27

software for all its users.  We, the Free Software Foundation, use the

28

GNU General Public License for most of our software; it applies also to

29

any other work released this way by its authors.  You can apply it to

30

your programs, too.</p>

31

32

<p>When we speak of free software, we are referring to freedom, not

33

price.  Our General Public Licenses are designed to make sure that you

34

have the freedom to distribute copies of free software (and charge for

35

them if you wish), that you receive source code or can get it if you

36

want it, that you can change the software or use pieces of it in new

37

free programs, and that you know you can do these things.</p>

38

39

<p>To protect your rights, we need to prevent others from denying you

40

these rights or asking you to surrender the rights.  Therefore, you have

41

certain responsibilities if you distribute copies of the software, or if

42

you modify it: responsibilities to respect the freedom of others.</p>

43

44

<p>For example, if you distribute copies of such a program, whether

45

gratis or for a fee, you must pass on to the recipients the same

46

freedoms that you received.  You must make sure that they, too, receive

47

or can get the source code.  And you must show them these terms so they

48

know their rights.</p>

49

50

<p>Developers that use the GNU GPL protect your rights with two steps:

51

(1) assert copyright on the software, and (2) offer you this License

52

giving you legal permission to copy, distribute and/or modify it.</p>

53

54

<p>For the developers' and authors' protection, the GPL clearly explains

55

that there is no warranty for this free software.  For both users' and

56

authors' sake, the GPL requires that modified versions be marked as

57

changed, so that their problems will not be attributed erroneously to

58

authors of previous versions.</p>

59

60

<p>Some devices are designed to deny users access to install or run

61

modified versions of the software inside them, although the manufacturer

62

can do so.  This is fundamentally incompatible with the aim of

63

protecting users' freedom to change the software.  The systematic

64

pattern of such abuse occurs in the area of products for individuals to

65

use, which is precisely where it is most unacceptable.  Therefore, we

66

have designed this version of the GPL to prohibit the practice for those

67

products.  If such problems arise substantially in other domains, we

68

stand ready to extend this provision to those domains in future versions

69

of the GPL, as needed to protect the freedom of users.</p>

70

71

<p>Finally, every program is threatened constantly by software patents.

72

States should not allow patents to restrict development and use of

73

software on general-purpose computers, but in those that do, we wish to

74

avoid the special danger that patents applied to a free program could

75

make it effectively proprietary.  To prevent this, the GPL assures that

76

patents cannot be used to render the program non-free.</p>

77

78

<p>The precise terms and conditions for copying, distribution and

79

modification follow.</p>

80

81

<h3><a name="terms"></a>TERMS AND CONDITIONS</h3>

82

83

<h4><a name="section0"></a>0. Definitions.</h4>

84

85

<p>“This License” refers to version 3 of the GNU General Public License.</p>

86

87

<p>“Copyright” also means copyright-like laws that apply to other kinds of

88

works, such as semiconductor masks.</p>

89

90

<p>“The Program” refers to any copyrightable work licensed under this

91

License.  Each licensee is addressed as “you”.  “Licensees” and

92

“recipients” may be individuals or organizations.</p>

93

94

<p>To “modify” a work means to copy from or adapt all or part of the work

95

in a fashion requiring copyright permission, other than the making of an

96

exact copy.  The resulting work is called a “modified version” of the

97

earlier work or a work “based on” the earlier work.</p>

98

99

<p>A “covered work” means either the unmodified Program or a work based

100

on the Program.</p>

101

102

<p>To “propagate” a work means to do anything with it that, without

103

permission, would make you directly or secondarily liable for

104

infringement under applicable copyright law, except executing it on a

105

computer or modifying a private copy.  Propagation includes copying,

106

distribution (with or without modification), making available to the

107

public, and in some countries other activities as well.</p>

108

109

<p>To “convey” a work means any kind of propagation that enables other

110

parties to make or receive copies.  Mere interaction with a user through

111

a computer network, with no transfer of a copy, is not conveying.</p>

112

113

<p>An interactive user interface displays “Appropriate Legal Notices”

114

to the extent that it includes a convenient and prominently visible

115

feature that (1) displays an appropriate copyright notice, and (2)

116

tells the user that there is no warranty for the work (except to the

117

extent that warranties are provided), that licensees may convey the

118

work under this License, and how to view a copy of this License.  If

119

the interface presents a list of user commands or options, such as a

120

menu, a prominent item in the list meets this criterion.</p>

121

122

<h4><a name="section1"></a>1. Source Code.</h4>

123

124

<p>The “source code” for a work means the preferred form of the work

125

for making modifications to it.  “Object code” means any non-source

126

form of a work.</p>

127

128

<p>A “Standard Interface” means an interface that either is an official

129

standard defined by a recognized standards body, or, in the case of

130

interfaces specified for a particular programming language, one that

131

is widely used among developers working in that language.</p>

132

133

<p>The “System Libraries” of an executable work include anything, other

134

than the work as a whole, that (a) is included in the normal form of

135

packaging a Major Component, but which is not part of that Major

136

Component, and (b) serves only to enable use of the work with that

137

Major Component, or to implement a Standard Interface for which an

138

implementation is available to the public in source code form.  A

139

“Major Component”, in this context, means a major essential component

140

(kernel, window system, and so on) of the specific operating system

141

(if any) on which the executable work runs, or a compiler used to

142

produce the work, or an object code interpreter used to run it.</p>

143

144

<p>The “Corresponding Source” for a work in object code form means all

145

the source code needed to generate, install, and (for an executable

146

work) run the object code and to modify the work, including scripts to

147

control those activities.  However, it does not include the work's

148

System Libraries, or general-purpose tools or generally available free

149

programs which are used unmodified in performing those activities but

150

which are not part of the work.  For example, Corresponding Source

151

includes interface definition files associated with source files for

152

the work, and the source code for shared libraries and dynamically

153

linked subprograms that the work is specifically designed to require,

154

such as by intimate data communication or control flow between those

155

subprograms and other parts of the work.</p>

156

157

<p>The Corresponding Source need not include anything that users

158

can regenerate automatically from other parts of the Corresponding

159

Source.</p>

160

161

<p>The Corresponding Source for a work in source code form is that

162

same work.</p>

163

164

<h4><a name="section2"></a>2. Basic Permissions.</h4>

165

166

<p>All rights granted under this License are granted for the term of

167

copyright on the Program, and are irrevocable provided the stated

168

conditions are met.  This License explicitly affirms your unlimited

169

permission to run the unmodified Program.  The output from running a

170

covered work is covered by this License only if the output, given its

171

content, constitutes a covered work.  This License acknowledges your

172

rights of fair use or other equivalent, as provided by copyright law.</p>

173

174

<p>You may make, run and propagate covered works that you do not

175

convey, without conditions so long as your license otherwise remains

176

in force.  You may convey covered works to others for the sole purpose

177

of having them make modifications exclusively for you, or provide you

178

with facilities for running those works, provided that you comply with

179

the terms of this License in conveying all material for which you do

180

not control copyright.  Those thus making or running the covered works

181

for you must do so exclusively on your behalf, under your direction

182

and control, on terms that prohibit them from making any copies of

183

your copyrighted material outside their relationship with you.</p>

184

185

<p>Conveying under any other circumstances is permitted solely under

186

the conditions stated below.  Sublicensing is not allowed; section 10

187

makes it unnecessary.</p>

188

189

<h4><a name="section3"></a>3. Protecting Users' Legal Rights From Anti-Circumvention Law.</h4>

190

191

<p>No covered work shall be deemed part of an effective technological

192

measure under any applicable law fulfilling obligations under article

193

11 of the WIPO copyright treaty adopted on 20 December 1996, or

194

similar laws prohibiting or restricting circumvention of such

195

measures.</p>

196

197

<p>When you convey a covered work, you waive any legal power to forbid

198

circumvention of technological measures to the extent such circumvention

199

is effected by exercising rights under this License with respect to

200

the covered work, and you disclaim any intention to limit operation or

201

modification of the work as a means of enforcing, against the work's

202

users, your or third parties' legal rights to forbid circumvention of

203

technological measures.</p>

204

205

<h4><a name="section4"></a>4. Conveying Verbatim Copies.</h4>

206

207

<p>You may convey verbatim copies of the Program's source code as you

208

receive it, in any medium, provided that you conspicuously and

209

appropriately publish on each copy an appropriate copyright notice;

210

keep intact all notices stating that this License and any

211

non-permissive terms added in accord with section 7 apply to the code;

212

keep intact all notices of the absence of any warranty; and give all

213

recipients a copy of this License along with the Program.</p>

214

215

<p>You may charge any price or no price for each copy that you convey,

216

and you may offer support or warranty protection for a fee.</p>

217

218

<h4><a name="section5"></a>5. Conveying Modified Source Versions.</h4>

219

220

<p>You may convey a work based on the Program, or the modifications to

221

produce it from the Program, in the form of source code under the

222

terms of section 4, provided that you also meet all of these conditions:</p>

223

224

<ul>

225

<li>a) The work must carry prominent notices stating that you modified

226

    it, and giving a relevant date.</li>

227

228

<li>b) The work must carry prominent notices stating that it is

229

    released under this License and any conditions added under section

230

    7.  This requirement modifies the requirement in section 4 to

231

    “keep intact all notices”.</li>

232

233

<li>c) You must license the entire work, as a whole, under this

234

    License to anyone who comes into possession of a copy.  This

235

    License will therefore apply, along with any applicable section 7

236

    additional terms, to the whole of the work, and all its parts,

237

    regardless of how they are packaged.  This License gives no

238

    permission to license the work in any other way, but it does not

239

    invalidate such permission if you have separately received it.</li>

240

241

<li>d) If the work has interactive user interfaces, each must display

242

    Appropriate Legal Notices; however, if the Program has interactive

243

    interfaces that do not display Appropriate Legal Notices, your

244

    work need not make them do so.</li>

245

</ul>

246

247

<p>A compilation of a covered work with other separate and independent

248

works, which are not by their nature extensions of the covered work,

249

and which are not combined with it such as to form a larger program,

250

in or on a volume of a storage or distribution medium, is called an

251

“aggregate” if the compilation and its resulting copyright are not

252

used to limit the access or legal rights of the compilation's users

253

beyond what the individual works permit.  Inclusion of a covered work

254

in an aggregate does not cause this License to apply to the other

255

parts of the aggregate.</p>

256

257

<h4><a name="section6"></a>6. Conveying Non-Source Forms.</h4>

258

259

<p>You may convey a covered work in object code form under the terms

260

of sections 4 and 5, provided that you also convey the

261

machine-readable Corresponding Source under the terms of this License,

262

in one of these ways:</p>

263

264

<ul>

265

<li>a) Convey the object code in, or embodied in, a physical product

266

    (including a physical distribution medium), accompanied by the

267

    Corresponding Source fixed on a durable physical medium

268

    customarily used for software interchange.</li>

269

270

<li>b) Convey the object code in, or embodied in, a physical product

271

    (including a physical distribution medium), accompanied by a

272

    written offer, valid for at least three years and valid for as

273

    long as you offer spare parts or customer support for that product

274

    model, to give anyone who possesses the object code either (1) a

275

    copy of the Corresponding Source for all the software in the

276

    product that is covered by this License, on a durable physical

277

    medium customarily used for software interchange, for a price no

278

    more than your reasonable cost of physically performing this

279

    conveying of source, or (2) access to copy the

280

    Corresponding Source from a network server at no charge.</li>

281

282

<li>c) Convey individual copies of the object code with a copy of the

283

    written offer to provide the Corresponding Source.  This

284

    alternative is allowed only occasionally and noncommercially, and

285

    only if you received the object code with such an offer, in accord

286

    with subsection 6b.</li>

287

288

<li>d) Convey the object code by offering access from a designated

289

    place (gratis or for a charge), and offer equivalent access to the

290

    Corresponding Source in the same way through the same place at no

291

    further charge.  You need not require recipients to copy the

292

    Corresponding Source along with the object code.  If the place to

293

    copy the object code is a network server, the Corresponding Source

294

    may be on a different server (operated by you or a third party)

295

    that supports equivalent copying facilities, provided you maintain

296

    clear directions next to the object code saying where to find the

297

    Corresponding Source.  Regardless of what server hosts the

298

    Corresponding Source, you remain obligated to ensure that it is

299

    available for as long as needed to satisfy these requirements.</li>

300

301

<li>e) Convey the object code using peer-to-peer transmission, provided

302

    you inform other peers where the object code and Corresponding

303

    Source of the work are being offered to the general public at no

304

    charge under subsection 6d.</li>

305

</ul>

306

307

<p>A separable portion of the object code, whose source code is excluded

308

from the Corresponding Source as a System Library, need not be

309

included in conveying the object code work.</p>

310

311

<p>A “User Product” is either (1) a “consumer product”, which means any

312

tangible personal property which is normally used for personal, family,

313

or household purposes, or (2) anything designed or sold for incorporation

314

into a dwelling.  In determining whether a product is a consumer product,

315

doubtful cases shall be resolved in favor of coverage.  For a particular

316

product received by a particular user, “normally used” refers to a

317

typical or common use of that class of product, regardless of the status

318

of the particular user or of the way in which the particular user

319

actually uses, or expects or is expected to use, the product.  A product

320

is a consumer product regardless of whether the product has substantial

321

commercial, industrial or non-consumer uses, unless such uses represent

322

the only significant mode of use of the product.</p>

323

324

<p>“Installation Information” for a User Product means any methods,

325

procedures, authorization keys, or other information required to install

326

and execute modified versions of a covered work in that User Product from

327

a modified version of its Corresponding Source.  The information must

328

suffice to ensure that the continued functioning of the modified object

329

code is in no case prevented or interfered with solely because

330

modification has been made.</p>

331

332

<p>If you convey an object code work under this section in, or with, or

333

specifically for use in, a User Product, and the conveying occurs as

334

part of a transaction in which the right of possession and use of the

335

User Product is transferred to the recipient in perpetuity or for a

336

fixed term (regardless of how the transaction is characterized), the

337

Corresponding Source conveyed under this section must be accompanied

338

by the Installation Information.  But this requirement does not apply

339

if neither you nor any third party retains the ability to install

340

modified object code on the User Product (for example, the work has

341

been installed in ROM).</p>

342

343

<p>The requirement to provide Installation Information does not include a

344

requirement to continue to provide support service, warranty, or updates

345

for a work that has been modified or installed by the recipient, or for

346

the User Product in which it has been modified or installed.  Access to a

347

network may be denied when the modification itself materially and

348

adversely affects the operation of the network or violates the rules and

349

protocols for communication across the network.</p>

350

351

<p>Corresponding Source conveyed, and Installation Information provided,

352

in accord with this section must be in a format that is publicly

353

documented (and with an implementation available to the public in

354

source code form), and must require no special password or key for

355

unpacking, reading or copying.</p>

356

357

<h4><a name="section7"></a>7. Additional Terms.</h4>

358

359

<p>“Additional permissions” are terms that supplement the terms of this

360

License by making exceptions from one or more of its conditions.

361

Additional permissions that are applicable to the entire Program shall

362

be treated as though they were included in this License, to the extent

363

that they are valid under applicable law.  If additional permissions

364

apply only to part of the Program, that part may be used separately

365

under those permissions, but the entire Program remains governed by

366

this License without regard to the additional permissions.</p>

367

368

<p>When you convey a copy of a covered work, you may at your option

369

remove any additional permissions from that copy, or from any part of

370

it.  (Additional permissions may be written to require their own

371

removal in certain cases when you modify the work.)  You may place

372

additional permissions on material, added by you to a covered work,

373

for which you have or can give appropriate copyright permission.</p>

374

375

<p>Notwithstanding any other provision of this License, for material you

376

add to a covered work, you may (if authorized by the copyright holders of

377

that material) supplement the terms of this License with terms:</p>

378

379

<ul>

380

<li>a) Disclaiming warranty or limiting liability differently from the

381

    terms of sections 15 and 16 of this License; or</li>

382

383

<li>b) Requiring preservation of specified reasonable legal notices or

384

    author attributions in that material or in the Appropriate Legal

385

    Notices displayed by works containing it; or</li>

386

387

<li>c) Prohibiting misrepresentation of the origin of that material, or

388

    requiring that modified versions of such material be marked in

389

    reasonable ways as different from the original version; or</li>

390

391

<li>d) Limiting the use for publicity purposes of names of licensors or

392

    authors of the material; or</li>

393

394

<li>e) Declining to grant rights under trademark law for use of some

395

    trade names, trademarks, or service marks; or</li>

396

397

<li>f) Requiring indemnification of licensors and authors of that

398

    material by anyone who conveys the material (or modified versions of

399

    it) with contractual assumptions of liability to the recipient, for

400

    any liability that these contractual assumptions directly impose on

401

    those licensors and authors.</li>

402

</ul>

403

404

<p>All other non-permissive additional terms are considered “further

405

restrictions” within the meaning of section 10.  If the Program as you

406

received it, or any part of it, contains a notice stating that it is

407

governed by this License along with a term that is a further

408

restriction, you may remove that term.  If a license document contains

409

a further restriction but permits relicensing or conveying under this

410

License, you may add to a covered work material governed by the terms

411

of that license document, provided that the further restriction does

412

not survive such relicensing or conveying.</p>

413

414

<p>If you add terms to a covered work in accord with this section, you

415

must place, in the relevant source files, a statement of the

416

additional terms that apply to those files, or a notice indicating

417

where to find the applicable terms.</p>

418

419

<p>Additional terms, permissive or non-permissive, may be stated in the

420

form of a separately written license, or stated as exceptions;

421

the above requirements apply either way.</p>

422

423

<h4><a name="section8"></a>8. Termination.</h4>

424

425

<p>You may not propagate or modify a covered work except as expressly

426

provided under this License.  Any attempt otherwise to propagate or

427

modify it is void, and will automatically terminate your rights under

428

this License (including any patent licenses granted under the third

429

paragraph of section 11).</p>

430

431

<p>However, if you cease all violation of this License, then your

432

license from a particular copyright holder is reinstated (a)

433

provisionally, unless and until the copyright holder explicitly and

434

finally terminates your license, and (b) permanently, if the copyright

435

holder fails to notify you of the violation by some reasonable means

prior to 60 days after the cessation.</p>

438

<p>Moreover, your license from a particular copyright holder is

439

reinstated permanently if the copyright holder notifies you of the

440

violation by some reasonable means, this is the first time you have

441

received notice of violation of this License (for any work) from that

442

copyright holder, and you cure the violation prior to 30 days after

443

your receipt of the notice.</p>

444

445

<p>Termination of your rights under this section does not terminate the

446

licenses of parties who have received copies or rights from you under

447

this License.  If your rights have been terminated and not permanently

448

reinstated, you do not qualify to receive new licenses for the same

449

material under section 10.</p>

<h4><a name="section9"></a>9. Acceptance Not Required for Having Copies.</h4>

452

453

<p>You are not required to accept this License in order to receive or

454

run a copy of the Program.  Ancillary propagation of a covered work

455

occurring solely as a consequence of using peer-to-peer transmission

456

to receive a copy likewise does not require acceptance.  However,

457

nothing other than this License grants you permission to propagate or

458

modify any covered work.  These actions infringe copyright if you do

459

not accept this License.  Therefore, by modifying or propagating a

460

covered work, you indicate your acceptance of this License to do so.</p>

461

462

<h4><a name="section10"></a>10. Automatic Licensing of Downstream Recipients.</h4>

463

464

<p>Each time you convey a covered work, the recipient automatically

465

receives a license from the original licensors, to run, modify and

466

propagate that work, subject to this License.  You are not responsible

467

for enforcing compliance by third parties with this License.</p>

468

469

<p>An “entity transaction” is a transaction transferring control of an

470

organization, or substantially all assets of one, or subdividing an

471

organization, or merging organizations.  If propagation of a covered

472

work results from an entity transaction, each party to that

473

transaction who receives a copy of the work also receives whatever

474

licenses to the work the party's predecessor in interest had or could

475

give under the previous paragraph, plus a right to possession of the

476

Corresponding Source of the work from the predecessor in interest, if

477

the predecessor has it or can get it with reasonable efforts.</p>

478

479

<p>You may not impose any further restrictions on the exercise of the

480

rights granted or affirmed under this License.  For example, you may

481

not impose a license fee, royalty, or other charge for exercise of

482

rights granted under this License, and you may not initiate litigation

483

(including a cross-claim or counterclaim in a lawsuit) alleging that

484

any patent claim is infringed by making, using, selling, offering for

485

sale, or importing the Program or any portion of it.</p>

<h4><a name="section11"></a>11. Patents.</h4>

488

489

<p>A “contributor” is a copyright holder who authorizes use under this

490

License of the Program or a work on which the Program is based.  The

491

work thus licensed is called the contributor's “contributor version”.</p>

492

493

<p>A contributor's “essential patent claims” are all patent claims

494

owned or controlled by the contributor, whether already acquired or

495

hereafter acquired, that would be infringed by some manner, permitted

496

by this License, of making, using, or selling its contributor version,

497

but do not include claims that would be infringed only as a
