/* ## 51 Franklin Steet, Fifth Floor, Boston, MA 02110-1301, USA */

16

/* ## Everyone is permitted to copy and distribute verbatim copies */

17

/* ## of this license document, but changing it is not allowed. */

18

19

/* ## Preamble */

20

21

/* ## The licenses for most software are designed to take away your */

22

/* ## freedom to share and change it. By contrast, the GNU General Public */

23

/* ## License is intended to guarantee your freedom to share and change free */

24

/* ## software--to make sure the software is free for all its users. This */

25

/* ## General Public License applies to most of the Free Software */

26

/* ## Foundation's software and to any other program whose authors commit to */

27

/* ## using it. (Some other Free Software Foundation software is covered by */

28

/* ## the GNU Library General Public License instead.) You can apply it to */

29

/* ## your programs, too. */

30

31

/* ## When we speak of free software, we are referring to freedom, not */

32

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

33

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

34

/* ## this service if you wish), that you receive source code or can get it */

35

/* ## if you want it, that you can change the software or use pieces of it */

36

/* ## in new free programs; and that you know you can do these things. */

37

38

/* ## To protect your rights, we need to make restrictions that forbid */

39

/* ## anyone to deny you these rights or to ask you to surrender the rights. */

40

/* ## These restrictions translate to certain responsibilities for you if you */

41

/* ## distribute copies of the software, or if you modify it. */

42

43

/* ## For example, if you distribute copies of such a program, whether */

44

/* ## gratis or for a fee, you must give the recipients all the rights that */

45

/* ## you have. You must make sure that they, too, receive or can get the */

46

/* ## source code. And you must show them these terms so they know their */

47

/* ## rights. */

48

49

/* ## We protect your rights with two steps: (1) copyright the software, and */

50

/* ## (2) offer you this license which gives you legal permission to copy, */

51

/* ## distribute and/or modify the software. */

52

53

/* ## Also, for each author's protection and ours, we want to make certain */

54

/* ## that everyone understands that there is no warranty for this free */

55

/* ## software. If the software is modified by someone else and passed on, we */

56

/* ## want its recipients to know that what they have is not the original, so */

57

/* ## that any problems introduced by others will not reflect on the original */

58

/* ## authors' reputations. */

59

60

/* ## Finally, any free program is threatened constantly by software */

61

/* ## patents. We wish to avoid the danger that redistributors of a free */

62

/* ## program will individually obtain patent licenses, in effect making the */

63

/* ## program proprietary. To prevent this, we have made it clear that any */

64

/* ## patent must be licensed for everyone's free use or not licensed at all. */

65

66

/* ## The precise terms and conditions for copying, distribution and */

67

/* ## modification follow. */

68

69

/* ## GNU GENERAL PUBLIC LICENSE */

70

/* ## TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION */

71

72

/* ## 0. This License applies to any program or other work which contains */

73

/* ## a notice placed by the copyright holder saying it may be distributed */

74

/* ## under the terms of this General Public License. The "Program", below, */

75

/* ## refers to any such program or work, and a "work based on the Program" */

76

/* ## means either the Program or any derivative work under copyright law: */

77

/* ## that is to say, a work containing the Program or a portion of it, */

78

/* ## either verbatim or with modifications and/or translated into another */

79

/* ## language. (Hereinafter, translation is included without limitation in */

80

/* ## the term "modification".) Each licensee is addressed as "you". */

81

82

/* ## Activities other than copying, distribution and modification are not */

83

/* ## covered by this License; they are outside its scope. The act of */

84

/* ## running the Program is not restricted, and the output from the Program */

85

/* ## is covered only if its contents constitute a work based on the */

86

/* ## Program (independent of having been made by running the Program). */

87

/* ## Whether that is true depends on what the Program does. */

88

89

/* ## 1. You may copy and distribute verbatim copies of the Program's */

90

/* ## source code as you receive it, in any medium, provided that you */

91

/* ## conspicuously and appropriately publish on each copy an appropriate */

92

/* ## copyright notice and disclaimer of warranty; keep intact all the */

93

/* ## notices that refer to this License and to the absence of any warranty; */

94

/* ## and give any other recipients of the Program a copy of this License */

95

/* ## along with the Program. */

96

97

/* ## You may charge a fee for the physical act of transferring a copy, and */

98

/* ## you may at your option offer warranty protection in exchange for a fee. */

99

100

/* ## 2. You may modify your copy or copies of the Program or any portion */

101

/* ## of it, thus forming a work based on the Program, and copy and */

102

/* ## distribute such modifications or work under the terms of Section 1 */

103

/* ## above, provided that you also meet all of these conditions: */

104

105

/* ## a) You must cause the modified files to carry prominent notices */

106

/* ## stating that you changed the files and the date of any change. */

107

108

/* ## b) You must cause any work that you distribute or publish, that in */

109

/* ## whole or in part contains or is derived from the Program or any */

110

/* ## part thereof, to be licensed as a whole at no charge to all third */

111

/* ## parties under the terms of this License. */

112

113

/* ## c) If the modified program normally reads commands interactively */

114

/* ## when run, you must cause it, when started running for such */

115

/* ## interactive use in the most ordinary way, to print or display an */

116

/* ## announcement including an appropriate copyright notice and a */

117

/* ## notice that there is no warranty (or else, saying that you provide */

118

/* ## a warranty) and that users may redistribute the program under */

119

/* ## these conditions, and telling the user how to view a copy of this */

120

/* ## License. (Exception: if the Program itself is interactive but */

121

/* ## does not normally print such an announcement, your work based on */

122

/* ## the Program is not required to print an announcement.) */

123

124

/* ## These requirements apply to the modified work as a whole. If */

125

/* ## identifiable sections of that work are not derived from the Program, */

126

/* ## and can be reasonably considered independent and separate works in */

127

/* ## themselves, then this License, and its terms, do not apply to those */

128

/* ## sections when you distribute them as separate works. But when you */

129

/* ## distribute the same sections as part of a whole which is a work based */

130

/* ## on the Program, the distribution of the whole must be on the terms of */

131

/* ## this License, whose permissions for other licensees extend to the */

132

/* ## entire whole, and thus to each and every part regardless of who wrote it. */

133

134

/* ## Thus, it is not the intent of this section to claim rights or contest */

135

/* ## your rights to work written entirely by you; rather, the intent is to */

136

/* ## exercise the right to control the distribution of derivative or */

137

/* ## collective works based on the Program. */

138

139

/* ## In addition, mere aggregation of another work not based on the Program */

140

/* ## with the Program (or with a work based on the Program) on a volume of */

141

/* ## a storage or distribution medium does not bring the other work under */

142

/* ## the scope of this License. */

143

144

/* ## 3. You may copy and distribute the Program (or a work based on it, */

145

/* ## under Section 2) in object code or executable form under the terms of */

146

/* ## Sections 1 and 2 above provided that you also do one of the following: */

147

148

/* ## a) Accompany it with the complete corresponding machine-readable */

149

/* ## source code, which must be distributed under the terms of Sections */

150

/* ## 1 and 2 above on a medium customarily used for software interchange; or, */

151

152

/* ## b) Accompany it with a written offer, valid for at least three */

153

/* ## years, to give any third party, for a charge no more than your */

154

/* ## cost of physically performing source distribution, a complete */

155

/* ## machine-readable copy of the corresponding source code, to be */

156

/* ## distributed under the terms of Sections 1 and 2 above on a medium */

157

/* ## customarily used for software interchange; or, */

158

159

/* ## c) Accompany it with the information you received as to the offer */

160

/* ## to distribute corresponding source code. (This alternative is */

161

/* ## allowed only for noncommercial distribution and only if you */

162

/* ## received the program in object code or executable form with such */

163

/* ## an offer, in accord with Subsection b above.) */

164

165

/* ## The source code for a work means the preferred form of the work for */

166

/* ## making modifications to it. For an executable work, complete source */

167

/* ## code means all the source code for all modules it contains, plus any */

168

/* ## associated interface definition files, plus the scripts used to */

169

/* ## control compilation and installation of the executable. However, as a */

170

/* ## special exception, the source code distributed need not include */

171

/* ## anything that is normally distributed (in either source or binary */

172

/* ## form) with the major components (compiler, kernel, and so on) of the */

173

/* ## operating system on which the executable runs, unless that component */

174

/* ## itself accompanies the executable. */

175

176

/* ## If distribution of executable or object code is made by offering */

177

/* ## access to copy from a designated place, then offering equivalent */

178

/* ## access to copy the source code from the same place counts as */

179

/* ## distribution of the source code, even though third parties are not */

180

/* ## compelled to copy the source along with the object code. */

181

182

/* ## 4. You may not copy, modify, sublicense, or distribute the Program */

183

/* ## except as expressly provided under this License. Any attempt */

184

/* ## otherwise to copy, modify, sublicense or distribute the Program is */

185

/* ## void, and will automatically terminate your rights under this License. */

186

/* ## However, parties who have received copies, or rights, from you under */

187

/* ## this License will not have their licenses terminated so long as such */

188

/* ## parties remain in full compliance. */

189

190

/* ## 5. You are not required to accept this License, since you have not */

191

/* ## signed it. However, nothing else grants you permission to modify or */

192

/* ## distribute the Program or its derivative works. These actions are */

193

/* ## prohibited by law if you do not accept this License. Therefore, by */

194

/* ## modifying or distributing the Program (or any work based on the */

195

/* ## Program), you indicate your acceptance of this License to do so, and */

196

/* ## all its terms and conditions for copying, distributing or modifying */

197

/* ## the Program or works based on it. */

198

199

/* ## 6. Each time you redistribute the Program (or any work based on the */

200

/* ## Program), the recipient automatically receives a license from the */

201

/* ## original licensor to copy, distribute or modify the Program subject to */

202

/* ## these terms and conditions. You may not impose any further */

203

/* ## restrictions on the recipients' exercise of the rights granted herein. */

204

/* ## You are not responsible for enforcing compliance by third parties to */

205

/* ## this License. */

206

207

/* ## 7. If, as a consequence of a court judgment or allegation of patent */

208

/* ## infringement or for any other reason (not limited to patent issues), */

209

/* ## conditions are imposed on you (whether by court order, agreement or */

210

/* ## otherwise) that contradict the conditions of this License, they do not */

211

/* ## excuse you from the conditions of this License. If you cannot */

212

/* ## distribute so as to satisfy simultaneously your obligations under this */

213

/* ## License and any other pertinent obligations, then as a consequence you */

214

/* ## may not distribute the Program at all. For example, if a patent */

215

/* ## license would not permit royalty-free redistribution of the Program by */

216

/* ## all those who receive copies directly or indirectly through you, then */

217

/* ## the only way you could satisfy both it and this License would be to */

218

/* ## refrain entirely from distribution of the Program. */

219

220

/* ## If any portion of this section is held invalid or unenforceable under */

221

/* ## any particular circumstance, the balance of the section is intended to */

222

/* ## apply and the section as a whole is intended to apply in other */

223

/* ## circumstances. */

224

225

/* ## It is not the purpose of this section to induce you to infringe any */

226

/* ## patents or other property right claims or to contest validity of any */

227

/* ## such claims; this section has the sole purpose of protecting the */

228

/* ## integrity of the free software distribution system, which is */

229

/* ## implemented by public license practices. Many people have made */

230

/* ## generous contributions to the wide range of software distributed */

231

/* ## through that system in reliance on consistent application of that */

232

/* ## system; it is up to the author/donor to decide if he or she is willing */

233

/* ## to distribute software through any other system and a licensee cannot */

234

/* ## impose that choice. */

235

236

/* ## This section is intended to make thoroughly clear what is believed to */

237

/* ## be a consequence of the rest of this License. */

238

239

/* ## 8. If the distribution and/or use of the Program is restricted in */

240

/* ## certain countries either by patents or by copyrighted interfaces, the */

241

/* ## original copyright holder who places the Program under this License */

242

/* ## may add an explicit geographical distribution limitation excluding */

243

/* ## those countries, so that distribution is permitted only in or among */

244

/* ## countries not thus excluded. In such case, this License incorporates */

245

/* ## the limitation as if written in the body of this License. */

246

247

/* ## 9. The Free Software Foundation may publish revised and/or new versions */

248

/* ## of the General Public License from time to time. Such new versions will */

249

/* ## be similar in spirit to the present version, but may differ in detail to */

250

/* ## address new problems or concerns. */

251

252

/* ## Each version is given a distinguishing version number. If the Program */

253

/* ## specifies a version number of this License which applies to it and "any */

254

/* ## later version", you have the option of following the terms and conditions */

255

/* ## either of that version or of any later version published by the Free */

256

/* ## Software Foundation. If the Program does not specify a version number of */

257

/* ## this License, you may choose any version ever published by the Free Software */

258

/* ## Foundation. */

259

260

/* ## 10. If you wish to incorporate parts of the Program into other free */

261

/* ## programs whose distribution conditions are different, write to the author */

262

/* ## to ask for permission. For software which is copyrighted by the Free */

263

/* ## Software Foundation, write to the Free Software Foundation; we sometimes */

264

/* ## make exceptions for this. Our decision will be guided by the two goals */

265

/* ## of preserving the free status of all derivatives of our free software and */

266

/* ## of promoting the sharing and reuse of software generally. */

267

268

/* ## NO WARRANTY */

269

270

/* ## 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY */

271

/* ## FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN */

272

/* ## OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES */

273

/* ## PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED */

274

/* ## OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF */

275

/* ## MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS */

276

/* ## TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE */

277

/* ## PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, */

278

/* ## REPAIR OR CORRECTION. */

279

280

/* ## 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING */

281

/* ## WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR */

282

/* ## REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, */

283

/* ## INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING */

284

/* ## OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED */

285

/* ## TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY */

286

/* ## YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER */

287

/* ## PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE */

288

/* ## POSSIBILITY OF SUCH DAMAGES. */

289

290

/* ## END OF TERMS AND CONDITIONS */

291

292

/* ## How to Apply These Terms to Your New Programs */

293

294

/* ## If you develop a new program, and you want it to be of the greatest */

295

/* ## possible use to the public, the best way to achieve this is to make it */

296

/* ## free software which everyone can redistribute and change under these terms. */

297

298

/* ## To do so, attach the following notices to the program. It is safest */

299

/* ## to attach them to the start of each source file to most effectively */

300

/* ## convey the exclusion of warranty; and each file should have at least */

301

/* ## the "copyright" line and a pointer to where the full notice is found. */
