 Everyone is permitted to copy and distribute verbatim copies

16

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

<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,
