                        Version 3, 29 June 2007

  Everyone is permitted to copy and distribute verbatim copies
6 2c5a656a Andreas
  of this license document, but changing it is not allowed.
7 2c5a656a Andreas
8 2c5a656a Andreas
                             Preamble
9 2c5a656a Andreas
10 2c5a656a Andreas
   The GNU General Public License is a free, copyleft license for
11 2c5a656a Andreas
 software and other kinds of works.
12 2c5a656a Andreas
13 2c5a656a Andreas
   The licenses for most software and other practical works are designed
14 2c5a656a Andreas
 to take away your freedom to share and change the works.  By contrast,
15 2c5a656a Andreas
 the GNU General Public License is intended to guarantee your freedom to
16 2c5a656a Andreas
 share and change all versions of a program--to make sure it remains free
17 2c5a656a Andreas
 software for all its users.  We, the Free Software Foundation, use the
18 2c5a656a Andreas
 GNU General Public License for most of our software; it applies also to
19 2c5a656a Andreas
 any other work released this way by its authors.  You can apply it to
20 2c5a656a Andreas
 your programs, too.
21 2c5a656a Andreas
22 2c5a656a Andreas
   When we speak of free software, we are referring to freedom, not
23 2c5a656a Andreas
 price.  Our General Public Licenses are designed to make sure that you
24 2c5a656a Andreas
 have the freedom to distribute copies of free software (and charge for
25 2c5a656a Andreas
 them if you wish), that you receive source code or can get it if you
26 2c5a656a Andreas
 want it, that you can change the software or use pieces of it in new
27 2c5a656a Andreas
 free programs, and that you know you can do these things.
28 2c5a656a Andreas
29 2c5a656a Andreas
   To protect your rights, we need to prevent others from denying you
30 2c5a656a Andreas
 these rights or asking you to surrender the rights.  Therefore, you have
31 2c5a656a Andreas
 certain responsibilities if you distribute copies of the software, or if
32 2c5a656a Andreas
 you modify it: responsibilities to respect the freedom of others.
33 2c5a656a Andreas
34 2c5a656a Andreas
   For example, if you distribute copies of such a program, whether
35 2c5a656a Andreas
 gratis or for a fee, you must pass on to the recipients the same
36 2c5a656a Andreas
 freedoms that you received.  You must make sure that they, too, receive
37 2c5a656a Andreas
 or can get the source code.  And you must show them these terms so they
38 2c5a656a Andreas
 know their rights.
39 2c5a656a Andreas
40 2c5a656a Andreas
   Developers that use the GNU GPL protect your rights with two steps:
41 2c5a656a Andreas
 (1) assert copyright on the software, and (2) offer you this License
42 2c5a656a Andreas
 giving you legal permission to copy, distribute and/or modify it.
43 2c5a656a Andreas
44 2c5a656a Andreas
   For the developers' and authors' protection, the GPL clearly explains
45 2c5a656a Andreas
 that there is no warranty for this free software.  For both users' and
46 2c5a656a Andreas
 authors' sake, the GPL requires that modified versions be marked as
47 2c5a656a Andreas
 changed, so that their problems will not be attributed erroneously to
48 2c5a656a Andreas
 authors of previous versions.
49 2c5a656a Andreas
50 2c5a656a Andreas
   Some devices are designed to deny users access to install or run
51 2c5a656a Andreas
 modified versions of the software inside them, although the manufacturer
52 2c5a656a Andreas
 can do so.  This is fundamentally incompatible with the aim of
53 2c5a656a Andreas
 protecting users' freedom to change the software.  The systematic
54 2c5a656a Andreas
 pattern of such abuse occurs in the area of products for individuals to
55 2c5a656a Andreas
 use, which is precisely where it is most unacceptable.  Therefore, we
56 2c5a656a Andreas
 have designed this version of the GPL to prohibit the practice for those
57 2c5a656a Andreas
 products.  If such problems arise substantially in other domains, we
58 2c5a656a Andreas
 stand ready to extend this provision to those domains in future versions
59 2c5a656a Andreas
 of the GPL, as needed to protect the freedom of users.
60 2c5a656a Andreas
61 2c5a656a Andreas
   Finally, every program is threatened constantly by software patents.
62 2c5a656a Andreas
 States should not allow patents to restrict development and use of
63 2c5a656a Andreas
 software on general-purpose computers, but in those that do, we wish to
64 2c5a656a Andreas
 avoid the special danger that patents applied to a free program could
65 2c5a656a Andreas
 make it effectively proprietary.  To prevent this, the GPL assures that
66 2c5a656a Andreas
 patents cannot be used to render the program non-free.
67 2c5a656a Andreas
68 2c5a656a Andreas
   The precise terms and conditions for copying, distribution and
69 2c5a656a Andreas
 modification follow.
70 2c5a656a Andreas
71 2c5a656a Andreas
                        TERMS AND CONDITIONS
72 2c5a656a Andreas
73 2c5a656a Andreas
   0. Definitions.
74 2c5a656a Andreas
75 2c5a656a Andreas
   "This License" refers to version 3 of the GNU General Public License.
76 2c5a656a Andreas
77 2c5a656a Andreas
   "Copyright" also means copyright-like laws that apply to other kinds of
78 2c5a656a Andreas
 works, such as semiconductor masks.
79 2c5a656a Andreas
80 2c5a656a Andreas
   "The Program" refers to any copyrightable work licensed under this
81 2c5a656a Andreas
 License.  Each licensee is addressed as "you".  "Licensees" and
82 2c5a656a Andreas
 "recipients" may be individuals or organizations.
83 2c5a656a Andreas
84 2c5a656a Andreas
   To "modify" a work means to copy from or adapt all or part of the work
85 2c5a656a Andreas
 in a fashion requiring copyright permission, other than the making of an
86 2c5a656a Andreas
 exact copy.  The resulting work is called a "modified version" of the
87 2c5a656a Andreas
 earlier work or a work "based on" the earlier work.
88 2c5a656a Andreas
89 2c5a656a Andreas
   A "covered work" means either the unmodified Program or a work based
90 2c5a656a Andreas
 on the Program.
91 2c5a656a Andreas
92 2c5a656a Andreas
   To "propagate" a work means to do anything with it that, without
93 2c5a656a Andreas
 permission, would make you directly or secondarily liable for
94 2c5a656a Andreas
 infringement under applicable copyright law, except executing it on a
95 2c5a656a Andreas
 computer or modifying a private copy.  Propagation includes copying,
96 2c5a656a Andreas
 distribution (with or without modification), making available to the
97 2c5a656a Andreas
 public, and in some countries other activities as well.
98 2c5a656a Andreas
99 2c5a656a Andreas
   To "convey" a work means any kind of propagation that enables other
100 2c5a656a Andreas
 parties to make or receive copies.  Mere interaction with a user through
101 2c5a656a Andreas
 a computer network, with no transfer of a copy, is not conveying.
102 2c5a656a Andreas
103 2c5a656a Andreas
   An interactive user interface displays "Appropriate Legal Notices"
104 2c5a656a Andreas
 to the extent that it includes a convenient and prominently visible
105 2c5a656a Andreas
 feature that (1) displays an appropriate copyright notice, and (2)
106 2c5a656a Andreas
 tells the user that there is no warranty for the work (except to the
107 2c5a656a Andreas
 extent that warranties are provided), that licensees may convey the
108 2c5a656a Andreas
 work under this License, and how to view a copy of this License.  If
109 2c5a656a Andreas
 the interface presents a list of user commands or options, such as a
110 2c5a656a Andreas
 menu, a prominent item in the list meets this criterion.
111 2c5a656a Andreas
112 2c5a656a Andreas
   1. Source Code.
113 2c5a656a Andreas
114 2c5a656a Andreas
   The "source code" for a work means the preferred form of the work
115 2c5a656a Andreas
 for making modifications to it.  "Object code" means any non-source
116 2c5a656a Andreas
 form of a work.
117 2c5a656a Andreas
118 2c5a656a Andreas
   A "Standard Interface" means an interface that either is an official
119 2c5a656a Andreas
 standard defined by a recognized standards body, or, in the case of
120 2c5a656a Andreas
 interfaces specified for a particular programming language, one that
121 2c5a656a Andreas
 is widely used among developers working in that language.
122 2c5a656a Andreas
123 2c5a656a Andreas
   The "System Libraries" of an executable work include anything, other
124 2c5a656a Andreas
 than the work as a whole, that (a) is included in the normal form of
125 2c5a656a Andreas
 packaging a Major Component, but which is not part of that Major
126 2c5a656a Andreas
 Component, and (b) serves only to enable use of the work with that
127 2c5a656a Andreas
 Major Component, or to implement a Standard Interface for which an
128 2c5a656a Andreas
 implementation is available to the public in source code form.  A
129 2c5a656a Andreas
 "Major Component", in this context, means a major essential component
130 2c5a656a Andreas
 (kernel, window system, and so on) of the specific operating system
131 2c5a656a Andreas
 (if any) on which the executable work runs, or a compiler used to
132 2c5a656a Andreas
 produce the work, or an object code interpreter used to run it.
133 2c5a656a Andreas
134 2c5a656a Andreas
   The "Corresponding Source" for a work in object code form means all
135 2c5a656a Andreas
 the source code needed to generate, install, and (for an executable
136 2c5a656a Andreas
 work) run the object code and to modify the work, including scripts to
137 2c5a656a Andreas
 control those activities.  However, it does not include the work's
138 2c5a656a Andreas
 System Libraries, or general-purpose tools or generally available free
139 2c5a656a Andreas
 programs which are used unmodified in performing those activities but
140 2c5a656a Andreas
 which are not part of the work.  For example, Corresponding Source
141 2c5a656a Andreas
 includes interface definition files associated with source files for
142 2c5a656a Andreas
 the work, and the source code for shared libraries and dynamically
143 2c5a656a Andreas
 linked subprograms that the work is specifically designed to require,
144 2c5a656a Andreas
 such as by intimate data communication or control flow between those
145 2c5a656a Andreas
 subprograms and other parts of the work.
146 2c5a656a Andreas
147 2c5a656a Andreas
   The Corresponding Source need not include anything that users
148 2c5a656a Andreas
 can regenerate automatically from other parts of the Corresponding
149 2c5a656a Andreas
 Source.
150 2c5a656a Andreas
151 2c5a656a Andreas
   The Corresponding Source for a work in source code form is that
152 2c5a656a Andreas
 same work.
153 2c5a656a Andreas
154 2c5a656a Andreas
   2. Basic Permissions.
155 2c5a656a Andreas
156 2c5a656a Andreas
   All rights granted under this License are granted for the term of
157 2c5a656a Andreas
 copyright on the Program, and are irrevocable provided the stated
158 2c5a656a Andreas
 conditions are met.  This License explicitly affirms your unlimited
159 2c5a656a Andreas
 permission to run the unmodified Program.  The output from running a
160 2c5a656a Andreas
 covered work is covered by this License only if the output, given its
161 2c5a656a Andreas
 content, constitutes a covered work.  This License acknowledges your
162 2c5a656a Andreas
 rights of fair use or other equivalent, as provided by copyright law.
163 2c5a656a Andreas
164 2c5a656a Andreas
   You may make, run and propagate covered works that you do not
165 2c5a656a Andreas
 convey, without conditions so long as your license otherwise remains
166 2c5a656a Andreas
 in force.  You may convey covered works to others for the sole purpose
167 2c5a656a Andreas
 of having them make modifications exclusively for you, or provide you
168 2c5a656a Andreas
 with facilities for running those works, provided that you comply with
169 2c5a656a Andreas
 the terms of this License in conveying all material for which you do
170 2c5a656a Andreas
 not control copyright.  Those thus making or running the covered works
171 2c5a656a Andreas
 for you must do so exclusively on your behalf, under your direction
172 2c5a656a Andreas
 and control, on terms that prohibit them from making any copies of
173 2c5a656a Andreas
 your copyrighted material outside their relationship with you.
174 2c5a656a Andreas
175 2c5a656a Andreas
   Conveying under any other circumstances is permitted solely under
176 2c5a656a Andreas
 the conditions stated below.  Sublicensing is not allowed; section 10
177 2c5a656a Andreas
 makes it unnecessary.
178 2c5a656a Andreas
179 2c5a656a Andreas
   3. Protecting Users' Legal Rights From Anti-Circumvention Law.
180 2c5a656a Andreas
181 2c5a656a Andreas
   No covered work shall be deemed part of an effective technological
182 2c5a656a Andreas
 measure under any applicable law fulfilling obligations under article
183 2c5a656a Andreas
 11 of the WIPO copyright treaty adopted on 20 December 1996, or
184 2c5a656a Andreas
 similar laws prohibiting or restricting circumvention of such
185 2c5a656a Andreas
 measures.
186 2c5a656a Andreas
187 2c5a656a Andreas
   When you convey a covered work, you waive any legal power to forbid
188 2c5a656a Andreas
 circumvention of technological measures to the extent such circumvention
189 2c5a656a Andreas
 is effected by exercising rights under this License with respect to
190 2c5a656a Andreas
 the covered work, and you disclaim any intention to limit operation or
191 2c5a656a Andreas
 modification of the work as a means of enforcing, against the work's
192 2c5a656a Andreas
 users, your or third parties' legal rights to forbid circumvention of
193 2c5a656a Andreas
 technological measures.
194 2c5a656a Andreas
195 2c5a656a Andreas
   4. Conveying Verbatim Copies.
196 2c5a656a Andreas
197 2c5a656a Andreas
   You may convey verbatim copies of the Program's source code as you
198 2c5a656a Andreas
 receive it, in any medium, provided that you conspicuously and
199 2c5a656a Andreas
 appropriately publish on each copy an appropriate copyright notice;
200 2c5a656a Andreas
 keep intact all notices stating that this License and any
201 2c5a656a Andreas
 non-permissive terms added in accord with section 7 apply to the code;
202 2c5a656a Andreas
 keep intact all notices of the absence of any warranty; and give all
203 2c5a656a Andreas
 recipients a copy of this License along with the Program.
204 2c5a656a Andreas
205 2c5a656a Andreas
   You may charge any price or no price for each copy that you convey,
206 2c5a656a Andreas
 and you may offer support or warranty protection for a fee.
207 2c5a656a Andreas
208 2c5a656a Andreas
   5. Conveying Modified Source Versions.
209 2c5a656a Andreas
210 2c5a656a Andreas
   You may convey a work based on the Program, or the modifications to
211 2c5a656a Andreas
 produce it from the Program, in the form of source code under the
212 2c5a656a Andreas
 terms of section 4, provided that you also meet all of these conditions:
213 2c5a656a Andreas
214 2c5a656a Andreas
     a) The work must carry prominent notices stating that you modified
215 2c5a656a Andreas
     it, and giving a relevant date.
216 2c5a656a Andreas
217 2c5a656a Andreas
     b) The work must carry prominent notices stating that it is
218 2c5a656a Andreas
     released under this License and any conditions added under section
219 2c5a656a Andreas
     7.  This requirement modifies the requirement in section 4 to
220 2c5a656a Andreas
     "keep intact all notices".
221 2c5a656a Andreas
222 2c5a656a Andreas
     c) You must license the entire work, as a whole, under this
223 2c5a656a Andreas
     License to anyone who comes into possession of a copy.  This
224 2c5a656a Andreas
     License will therefore apply, along with any applicable section 7
225 2c5a656a Andreas
     additional terms, to the whole of the work, and all its parts,
226 2c5a656a Andreas
     regardless of how they are packaged.  This License gives no
227 2c5a656a Andreas
     permission to license the work in any other way, but it does not
228 2c5a656a Andreas
     invalidate such permission if you have separately received it.
229 2c5a656a Andreas
230 2c5a656a Andreas
     d) If the work has interactive user interfaces, each must display
231 2c5a656a Andreas
     Appropriate Legal Notices; however, if the Program has interactive
232 2c5a656a Andreas
     interfaces that do not display Appropriate Legal Notices, your
233 2c5a656a Andreas
     work need not make them do so.
234 2c5a656a Andreas
235 2c5a656a Andreas
   A compilation of a covered work with other separate and independent
236 2c5a656a Andreas
 works, which are not by their nature extensions of the covered work,
237 2c5a656a Andreas
 and which are not combined with it such as to form a larger program,
238 2c5a656a Andreas
 in or on a volume of a storage or distribution medium, is called an
239 2c5a656a Andreas
 "aggregate" if the compilation and its resulting copyright are not
240 2c5a656a Andreas
 used to limit the access or legal rights of the compilation's users
241 2c5a656a Andreas
 beyond what the individual works permit.  Inclusion of a covered work
242 2c5a656a Andreas
 in an aggregate does not cause this License to apply to the other
243 2c5a656a Andreas
 parts of the aggregate.
244 2c5a656a Andreas
245 2c5a656a Andreas
   6. Conveying Non-Source Forms.
246 2c5a656a Andreas
247 2c5a656a Andreas
   You may convey a covered work in object code form under the terms
248 2c5a656a Andreas
 of sections 4 and 5, provided that you also convey the
249 2c5a656a Andreas
 machine-readable Corresponding Source under the terms of this License,
250 2c5a656a Andreas
 in one of these ways:
251 2c5a656a Andreas
252 2c5a656a Andreas
     a) Convey the object code in, or embodied in, a physical product
253 2c5a656a Andreas
     (including a physical distribution medium), accompanied by the
254 2c5a656a Andreas
     Corresponding Source fixed on a durable physical medium
255 2c5a656a Andreas
     customarily used for software interchange.
256 2c5a656a Andreas
257 2c5a656a Andreas
     b) Convey the object code in, or embodied in, a physical product
258 2c5a656a Andreas
     (including a physical distribution medium), accompanied by a
259 2c5a656a Andreas
     written offer, valid for at least three years and valid for as
260 2c5a656a Andreas
     long as you offer spare parts or customer support for that product
261 2c5a656a Andreas
     model, to give anyone who possesses the object code either (1) a
262 2c5a656a Andreas
     copy of the Corresponding Source for all the software in the
263 2c5a656a Andreas
     product that is covered by this License, on a durable physical
264 2c5a656a Andreas
     medium customarily used for software interchange, for a price no
265 2c5a656a Andreas
     more than your reasonable cost of physically performing this
266 2c5a656a Andreas
     conveying of source, or (2) access to copy the
267 2c5a656a Andreas
     Corresponding Source from a network server at no charge.
268 2c5a656a Andreas
269 2c5a656a Andreas
     c) Convey individual copies of the object code with a copy of the
270 2c5a656a Andreas
     written offer to provide the Corresponding Source.  This
271 2c5a656a Andreas
     alternative is allowed only occasionally and noncommercially, and
272 2c5a656a Andreas
     only if you received the object code with such an offer, in accord
273 2c5a656a Andreas
     with subsection 6b.
274 2c5a656a Andreas
275 2c5a656a Andreas
     d) Convey the object code by offering access from a designated
276 2c5a656a Andreas
     place (gratis or for a charge), and offer equivalent access to the
277 2c5a656a Andreas
     Corresponding Source in the same way through the same place at no
278 2c5a656a Andreas
     further charge.  You need not require recipients to copy the
279 2c5a656a Andreas
     Corresponding Source along with the object code.  If the place to
280 2c5a656a Andreas
     copy the object code is a network server, the Corresponding Source
281 2c5a656a Andreas
     may be on a different server (operated by you or a third party)
282 2c5a656a Andreas
     that supports equivalent copying facilities, provided you maintain
283 2c5a656a Andreas
     clear directions next to the object code saying where to find the
284 2c5a656a Andreas
     Corresponding Source.  Regardless of what server hosts the
285 2c5a656a Andreas
     Corresponding Source, you remain obligated to ensure that it is
286 2c5a656a Andreas
     available for as long as needed to satisfy these requirements.
287 2c5a656a Andreas
288 2c5a656a Andreas
     e) Convey the object code using peer-to-peer transmission, provided
289 2c5a656a Andreas
     you inform other peers where the object code and Corresponding
290 2c5a656a Andreas
     Source of the work are being offered to the general public at no
291 2c5a656a Andreas
     charge under subsection 6d.
292 2c5a656a Andreas
293 2c5a656a Andreas
   A separable portion of the object code, whose source code is excluded
294 2c5a656a Andreas
 from the Corresponding Source as a System Library, need not be
295 2c5a656a Andreas
 included in conveying the object code work.
296 2c5a656a Andreas
297 2c5a656a Andreas
   A "User Product" is either (1) a "consumer product", which means any
298 2c5a656a Andreas
 tangible personal property which is normally used for personal, family,
299 2c5a656a Andreas
 or household purposes, or (2) anything designed or sold for incorporation
300 2c5a656a Andreas
 into a dwelling.  In determining whether a product is a consumer product,
301 2c5a656a Andreas
 doubtful cases shall be resolved in favor of coverage.  For a particular
302 2c5a656a Andreas
 product received by a particular user, "normally used" refers to a
303 2c5a656a Andreas
 typical or common use of that class of product, regardless of the status
304 2c5a656a Andreas
 of the particular user or of the way in which the particular user
305 2c5a656a Andreas
 actually uses, or expects or is expected to use, the product.  A product
306 2c5a656a Andreas
 is a consumer product regardless of whether the product has substantial
307 2c5a656a Andreas
 commercial, industrial or non-consumer uses, unless such uses represent
308 2c5a656a Andreas
 the only significant mode of use of the product.
309 2c5a656a Andreas
310 2c5a656a Andreas
   "Installation Information" for a User Product means any methods,
311 2c5a656a Andreas
 procedures, authorization keys, or other information required to install
312 2c5a656a Andreas
 and execute modified versions of a covered work in that User Product from
313 2c5a656a Andreas
 a modified version of its Corresponding Source.  The information must
314 2c5a656a Andreas
 suffice to ensure that the continued functioning of the modified object
315 2c5a656a Andreas
 code is in no case prevented or interfered with solely because
316 2c5a656a Andreas
 modification has been made.
317 2c5a656a Andreas
318 2c5a656a Andreas
   If you convey an object code work under this section in, or with, or
319 2c5a656a Andreas
 specifically for use in, a User Product, and the conveying occurs as
320 2c5a656a Andreas
 part of a transaction in which the right of possession and use of the
321 2c5a656a Andreas
 User Product is transferred to the recipient in perpetuity or for a
322 2c5a656a Andreas
 fixed term (regardless of how the transaction is characterized), the
323 2c5a656a Andreas
 Corresponding Source conveyed under this section must be accompanied
324 2c5a656a Andreas
 by the Installation Information.  But this requirement does not apply
325 2c5a656a Andreas
 if neither you nor any third party retains the ability to install
326 2c5a656a Andreas
 modified object code on the User Product (for example, the work has
327 2c5a656a Andreas
 been installed in ROM).
328 2c5a656a Andreas
329 2c5a656a Andreas
   The requirement to provide Installation Information does not include a
330 2c5a656a Andreas
 requirement to continue to provide support service, warranty, or updates
331 2c5a656a Andreas
 for a work that has been modified or installed by the recipient, or for
332 2c5a656a Andreas
 the User Product in which it has been modified or installed.  Access to a
333 2c5a656a Andreas
 network may be denied when the modification itself materially and
334 2c5a656a Andreas
 adversely affects the operation of the network or violates the rules and
335 2c5a656a Andreas
 protocols for communication across the network.
336 2c5a656a Andreas
337 2c5a656a Andreas
   Corresponding Source conveyed, and Installation Information provided,
338 2c5a656a Andreas
 in accord with this section must be in a format that is publicly
339 2c5a656a Andreas
 documented (and with an implementation available to the public in
340 2c5a656a Andreas
 source code form), and must require no special password or key for
341 2c5a656a Andreas
 unpacking, reading or copying.
342 2c5a656a Andreas
343 2c5a656a Andreas
   7. Additional Terms.
344 2c5a656a Andreas
345 2c5a656a Andreas
   "Additional permissions" are terms that supplement the terms of this
346 2c5a656a Andreas
 License by making exceptions from one or more of its conditions.
347 2c5a656a Andreas
 Additional permissions that are applicable to the entire Program shall
348 2c5a656a Andreas
 be treated as though they were included in this License, to the extent
349 2c5a656a Andreas
 that they are valid under applicable law.  If additional permissions
350 2c5a656a Andreas
 apply only to part of the Program, that part may be used separately
351 2c5a656a Andreas
 under those permissions, but the entire Program remains governed by
352 2c5a656a Andreas
 this License without regard to the additional permissions.
353 2c5a656a Andreas
354 2c5a656a Andreas
   When you convey a copy of a covered work, you may at your option
355 2c5a656a Andreas
 remove any additional permissions from that copy, or from any part of
356 2c5a656a Andreas
 it.  (Additional permissions may be written to require their own
357 2c5a656a Andreas
 removal in certain cases when you modify the work.)  You may place
358 2c5a656a Andreas
 additional permissions on material, added by you to a covered work,
359 2c5a656a Andreas
 for which you have or can give appropriate copyright permission.
360 2c5a656a Andreas
361 2c5a656a Andreas
   Notwithstanding any other provision of this License, for material you
362 2c5a656a Andreas
 add to a covered work, you may (if authorized by the copyright holders of
363 2c5a656a Andreas
 that material) supplement the terms of this License with terms:
364 2c5a656a Andreas
365 2c5a656a Andreas
     a) Disclaiming warranty or limiting liability differently from the
366 2c5a656a Andreas
     terms of sections 15 and 16 of this License; or
367 2c5a656a Andreas
368 2c5a656a Andreas
     b) Requiring preservation of specified reasonable legal notices or
369 2c5a656a Andreas
     author attributions in that material or in the Appropriate Legal
370 2c5a656a Andreas
     Notices displayed by works containing it; or
371 2c5a656a Andreas
372 2c5a656a Andreas
     c) Prohibiting misrepresentation of the origin of that material, or
373 2c5a656a Andreas
     requiring that modified versions of such material be marked in
374 2c5a656a Andreas
     reasonable ways as different from the original version; or
375 2c5a656a Andreas
376 2c5a656a Andreas
     d) Limiting the use for publicity purposes of names of licensors or
377 2c5a656a Andreas
     authors of the material; or
378 2c5a656a Andreas
379 2c5a656a Andreas
     e) Declining to grant rights under trademark law for use of some
380 2c5a656a Andreas
     trade names, trademarks, or service marks; or
381 2c5a656a Andreas
382 2c5a656a Andreas
     f) Requiring indemnification of licensors and authors of that
383 2c5a656a Andreas
     material by anyone who conveys the material (or modified versions of
384 2c5a656a Andreas
     it) with contractual assumptions of liability to the recipient, for
385 2c5a656a Andreas
     any liability that these contractual assumptions directly impose on
386 2c5a656a Andreas
     those licensors and authors.
387 2c5a656a Andreas
388 2c5a656a Andreas
   All other non-permissive additional terms are considered "further
389 2c5a656a Andreas
 restrictions" within the meaning of section 10.  If the Program as you
390 2c5a656a Andreas
 received it, or any part of it, contains a notice stating that it is
391 2c5a656a Andreas
 governed by this License along with a term that is a further
392 2c5a656a Andreas
 restriction, you may remove that term.  If a license document contains
393 2c5a656a Andreas
 a further restriction but permits relicensing or conveying under this
394 2c5a656a Andreas
 License, you may add to a covered work material governed by the terms
395 2c5a656a Andreas
 of that license document, provided that the further restriction does
396 2c5a656a Andreas
 not survive such relicensing or conveying.
397 2c5a656a Andreas
398 2c5a656a Andreas
   If you add terms to a covered work in accord with this section, you
399 2c5a656a Andreas
 must place, in the relevant source files, a statement of the
400 2c5a656a Andreas
 additional terms that apply to those files, or a notice indicating
401 2c5a656a Andreas
 where to find the applicable terms.
402 2c5a656a Andreas
403 2c5a656a Andreas
   Additional terms, permissive or non-permissive, may be stated in the
404 2c5a656a Andreas
 form of a separately written license, or stated as exceptions;
405 2c5a656a Andreas
 the above requirements apply either way.
406 2c5a656a Andreas
407 2c5a656a Andreas
   8. Termination.
408 2c5a656a Andreas
409 2c5a656a Andreas
   You may not propagate or modify a covered work except as expressly
410 2c5a656a Andreas
 provided under this License.  Any attempt otherwise to propagate or
411 2c5a656a Andreas
 modify it is void, and will automatically terminate your rights under
412 2c5a656a Andreas
 this License (including any patent licenses granted under the third
413 2c5a656a Andreas
 paragraph of section 11).
414 2c5a656a Andreas
415 2c5a656a Andreas
   However, if you cease all violation of this License, then your
416 2c5a656a Andreas
 license from a particular copyright holder is reinstated (a)
417 2c5a656a Andreas
 provisionally, unless and until the copyright holder explicitly and
418 2c5a656a Andreas
 finally terminates your license, and (b) permanently, if the copyright
419 2c5a656a Andreas
 holder fails to notify you of the violation by some reasonable means
420 2c5a656a Andreas
 prior to 60 days after the cessation.
421 2c5a656a Andreas
422 2c5a656a Andreas
   Moreover, your license from a particular copyright holder is
423 2c5a656a Andreas
 reinstated permanently if the copyright holder notifies you of the
424 2c5a656a Andreas
 violation by some reasonable means, this is the first time you have
425 2c5a656a Andreas
 received notice of violation of this License (for any work) from that
426 2c5a656a Andreas
 copyright holder, and you cure the violation prior to 30 days after
427 2c5a656a Andreas
 your receipt of the notice.
428 2c5a656a Andreas
429 2c5a656a Andreas
   Termination of your rights under this section does not terminate the
430 2c5a656a Andreas
 licenses of parties who have received copies or rights from you under
431 2c5a656a Andreas
 this License.  If your rights have been terminated and not permanently
432 2c5a656a Andreas
 reinstated, you do not qualify to receive new licenses for the same
433 2c5a656a Andreas
 material under section 10.
434 2c5a656a Andreas
435 2c5a656a Andreas
   9. Acceptance Not Required for Having Copies.
436 2c5a656a Andreas
437 2c5a656a Andreas
   You are not required to accept this License in order to receive or
438 2c5a656a Andreas
 run a copy of the Program.  Ancillary propagation of a covered work
439 2c5a656a Andreas
 occurring solely as a consequence of using peer-to-peer transmission
440 2c5a656a Andreas
 to receive a copy likewise does not require acceptance.  However,
441 2c5a656a Andreas
 nothing other than this License grants you permission to propagate or
442 2c5a656a Andreas
 modify any covered work.  These actions infringe copyright if you do
443 2c5a656a Andreas
 not accept this License.  Therefore, by modifying or propagating a
444 2c5a656a Andreas
 covered work, you indicate your acceptance of this License to do so.
445 2c5a656a Andreas
446 2c5a656a Andreas
   10. Automatic Licensing of Downstream Recipients.
447 2c5a656a Andreas
448 2c5a656a Andreas
   Each time you convey a covered work, the recipient automatically
449 2c5a656a Andreas
 receives a license from the original licensors, to run, modify and
450 2c5a656a Andreas
 propagate that work, subject to this License.  You are not responsible
451 2c5a656a Andreas
 for enforcing compliance by third parties with this License.
452 2c5a656a Andreas
453 2c5a656a Andreas
   An "entity transaction" is a transaction transferring control of an
454 2c5a656a Andreas
 organization, or substantially all assets of one, or subdividing an
455 2c5a656a Andreas
 organization, or merging organizations.  If propagation of a covered
456 2c5a656a Andreas
 work results from an entity transaction, each party to that
457 2c5a656a Andreas
 transaction who receives a copy of the work also receives whatever
458 2c5a656a Andreas
 licenses to the work the party's predecessor in interest had or could
459 2c5a656a Andreas
 give under the previous paragraph, plus a right to possession of the
460 2c5a656a Andreas
 Corresponding Source of the work from the predecessor in interest, if
461 2c5a656a Andreas
 the predecessor has it or can get it with reasonable efforts.
462 2c5a656a Andreas
463 2c5a656a Andreas
   You may not impose any further restrictions on the exercise of the
464 2c5a656a Andreas
 rights granted or affirmed under this License.  For example, you may
465 2c5a656a Andreas
 not impose a license fee, royalty, or other charge for exercise of
466 2c5a656a Andreas
 rights granted under this License, and you may not initiate litigation
467 2c5a656a Andreas
 (including a cross-claim or counterclaim in a lawsuit) alleging that
468 2c5a656a Andreas
 any patent claim is infringed by making, using, selling, offering for
469 2c5a656a Andreas
 sale, or importing the Program or any portion of it.
470 2c5a656a Andreas
471 2c5a656a Andreas
   11. Patents.
472 2c5a656a Andreas
473 2c5a656a Andreas
   A "contributor" is a copyright holder who authorizes use under this
474 2c5a656a Andreas
 License of the Program or a work on which the Program is based.  The
475 2c5a656a Andreas
 work thus licensed is called the contributor's "contributor version".
476 2c5a656a Andreas
477 2c5a656a Andreas
   A contributor's "essential patent claims" are all patent claims
478 2c5a656a Andreas
 owned or controlled by the contributor, whether already acquired or
479 2c5a656a Andreas
 hereafter acquired, that would be infringed by some manner, permitted
480 2c5a656a Andreas
 by this License, of making, using, or selling its contributor version,
481 2c5a656a Andreas
 but do not include claims that would be infringed only as a
482 2c5a656a Andreas
 consequence of further modification of the contributor version.  For
483 2c5a656a Andreas
 purposes of this definition, "control" includes the right to grant
484 2c5a656a Andreas
 patent sublicenses in a manner consistent with the requirements of
485 2c5a656a Andreas
 this License.
486 2c5a656a Andreas
487 2c5a656a Andreas
   Each contributor grants you a non-exclusive, worldwide, royalty-free
488 2c5a656a Andreas
 patent license under the contributor's essential patent claims, to
489 2c5a656a Andreas
 make, use, sell, offer for sale, import and otherwise run, modify and
490 2c5a656a Andreas
 propagate the contents of its contributor version.
491 2c5a656a Andreas
492 2c5a656a Andreas
   In the following three paragraphs, a "patent license" is any express
493 2c5a656a Andreas
 agreement or commitment, however denominated, not to enforce a patent
494 2c5a656a Andreas
 (such as an express permission to practice a patent or covenant not to
495 2c5a656a Andreas
 sue for patent infringement).  To "grant" such a patent license to a
496 2c5a656a Andreas
 party means to make such an agreement or commitment not to enforce a
497 2c5a656a Andreas
 patent against the party.
498 2c5a656a Andreas
499 2c5a656a Andreas
   If you convey a covered work, knowingly relying on a patent license,
500 2c5a656a Andreas
 and the Corresponding Source of the work is not available for anyone
501 2c5a656a Andreas
 to copy, free of charge and under the terms of this License, through a
502 2c5a656a Andreas
 publicly available network server or other readily accessible means,
503 2c5a656a Andreas
 then you must either (1) cause the Corresponding Source to be so
504 2c5a656a Andreas
 available, or (2) arrange to deprive yourself of the benefit of the
505 2c5a656a Andreas
 patent license for this particular work, or (3) arrange, in a manner
506 2c5a656a Andreas
 consistent with the requirements of this License, to extend the patent
507 2c5a656a Andreas
 license to downstream recipients.  "Knowingly relying" means you have
508 2c5a656a Andreas
 actual knowledge that, but for the patent license, your conveying the
509 2c5a656a Andreas
 covered work in a country, or your recipient's use of the covered work
510 2c5a656a Andreas
 in a country, would infringe one or more identifiable patents in that
511 2c5a656a Andreas
 country that you have reason to believe are valid.
512 2c5a656a Andreas
513 2c5a656a Andreas
   If, pursuant to or in connection with a single transaction or
514 2c5a656a Andreas
 arrangement, you convey, or propagate by procuring conveyance of, a
515 2c5a656a Andreas
 covered work, and grant a patent license to some of the parties
516 2c5a656a Andreas
 receiving the covered work authorizing them to use, propagate, modify
517 2c5a656a Andreas
 or convey a specific copy of the covered work, then the patent license
518 2c5a656a Andreas
 you grant is automatically extended to all recipients of the covered
519 2c5a656a Andreas
 work and works based on it.
520 2c5a656a Andreas
521 2c5a656a Andreas
   A patent license is "discriminatory" if it does not include within
522 2c5a656a Andreas
 the scope of its coverage, prohibits the exercise of, or is
523 2c5a656a Andreas
 conditioned on the non-exercise of one or more of the rights that are
524 2c5a656a Andreas
 specifically granted under this License.  You may not convey a covered
525 2c5a656a Andreas
 work if you are a party to an arrangement with a third party that is
526 2c5a656a Andreas
 in the business of distributing software, under which you make payment
527 2c5a656a Andreas
 to the third party based on the extent of your activity of conveying
528 2c5a656a Andreas
 the work, and under which the third party grants, to any of the
529 2c5a656a Andreas
 parties who would receive the covered work from you, a discriminatory
530 2c5a656a Andreas
 patent license (a) in connection with copies of the covered work
531 2c5a656a Andreas
 conveyed by you (or copies made from those copies), or (b) primarily
532 2c5a656a Andreas
 for and in connection with specific products or compilations that
533 2c5a656a Andreas
 contain the covered work, unless you entered into that arrangement,
534 2c5a656a Andreas
 or that patent license was granted, prior to 28 March 2007.
535 2c5a656a Andreas
536 2c5a656a Andreas
   Nothing in this License shall be construed as excluding or limiting
537 2c5a656a Andreas
 any implied license or other defenses to infringement that may
538 2c5a656a Andreas
 otherwise be available to you under applicable patent law.
539 2c5a656a Andreas
540 2c5a656a Andreas
   12. No Surrender of Others' Freedom.
541 2c5a656a Andreas
542 2c5a656a Andreas
   If conditions are imposed on you (whether by court order, agreement or
543 2c5a656a Andreas
 otherwise) that contradict the conditions of this License, they do not
544 2c5a656a Andreas
 excuse you from the conditions of this License.  If you cannot convey a
545 2c5a656a Andreas
 covered work so as to satisfy simultaneously your obligations under this
546 2c5a656a Andreas
 License and any other pertinent obligations, then as a consequence you may
547 2c5a656a Andreas
 not convey it at all.  For example, if you agree to terms that obligate you
548 2c5a656a Andreas
 to collect a royalty for further conveying from those to whom you convey
549 2c5a656a Andreas
 the Program, the only way you could satisfy both those terms and this
550 2c5a656a Andreas
 License would be to refrain entirely from conveying the Program.
551 2c5a656a Andreas
552 2c5a656a Andreas
   13. Use with the GNU Affero General Public License.
553 2c5a656a Andreas
554 2c5a656a Andreas
   Notwithstanding any other provision of this License, you have
555 2c5a656a Andreas
 permission to link or combine any covered work with a work licensed
556 2c5a656a Andreas
 under version 3 of the GNU Affero General Public License into a single
557 2c5a656a Andreas
 combined work, and to convey the resulting work.  The terms of this
558 2c5a656a Andreas
 License will continue to apply to the part which is the covered work,
559 2c5a656a Andreas
 but the special requirements of the GNU Affero General Public License,
560 2c5a656a Andreas
 section 13, concerning interaction through a network will apply to the
561 2c5a656a Andreas
 combination as such.
562 2c5a656a Andreas
563 2c5a656a Andreas
   14. Revised Versions of this License.
564 2c5a656a Andreas
565 2c5a656a Andreas
   The Free Software Foundation may publish revised and/or new versions of
566 2c5a656a Andreas
 the GNU General Public License from time to time.  Such new versions will
567 2c5a656a Andreas
 be similar in spirit to the present version, but may differ in detail to
568 2c5a656a Andreas
 address new problems or concerns.
569 2c5a656a Andreas
570 2c5a656a Andreas
   Each version is given a distinguishing version number.  If the
571 2c5a656a Andreas
 Program specifies that a certain numbered version of the GNU General
572 2c5a656a Andreas
 Public License "or any later version" applies to it, you have the
573 2c5a656a Andreas
 option of following the terms and conditions either of that numbered

 Foundation.  If the Program does not specify a version number of the

   If the Program specifies that a proxy can decide which future
580 2c5a656a Andreas
 versions of the GNU General Public License can be used, that proxy's
581 2c5a656a Andreas
 public statement of acceptance of a version permanently authorizes you
582 2c5a656a Andreas
 to choose that version for the Program.
583 2c5a656a Andreas
584 2c5a656a Andreas
   Later license versions may give you additional or different
585 2c5a656a Andreas
 permissions.  However, no additional obligations are imposed on any
586 2c5a656a Andreas
 author or copyright holder as a result of your choosing to follow a

   IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
603 2c5a656a Andreas
 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
604 2c5a656a Andreas

 DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
608 2c5a656a Andreas

   17. Interpretation of Sections 15 and 16.
613 2c5a656a Andreas
614 2c5a656a Andreas
   If the disclaimer of warranty and limitation of liability provided
615 2c5a656a Andreas
 above cannot be given local legal effect according to their terms,
616 2c5a656a Andreas
 reviewing courts shall apply local law that most closely approximates
617 2c5a656a Andreas
 an absolute waiver of all civil liability in connection with the
618 2c5a656a Andreas
 Program, unless a warranty or assumption of liability accompanies a
619 2c5a656a Andreas
 copy of the Program in return for a fee.

             How to Apply These Terms to Your New Programs
624 2c5a656a Andreas
625 2c5a656a Andreas
   If you develop a new program, and you want it to be of the greatest
626 2c5a656a Andreas
 possible use to the public, the best way to achieve this is to make it
627 2c5a656a Andreas
 free software which everyone can redistribute and change under these terms.
628 2c5a656a Andreas
629 2c5a656a Andreas
   To do so, attach the following notices to the program.  It is safest
630 2c5a656a Andreas
 to attach them to the start of each source file to most effectively
631 2c5a656a Andreas
 state the exclusion of warranty; and each file should have at least
632 2c5a656a Andreas
 the "copyright" line and a pointer to where the full notice is found.
633 2c5a656a Andreas
634 2c5a656a Andreas
     <one line to give the program's name and a brief idea of what it does.>

     You should have received a copy of the GNU General Public License
648 2c5a656a Andreas

650 2c5a656a Andreas
 Also add information on how to contact you by electronic and paper mail.
651 2c5a656a Andreas
652 2c5a656a Andreas
   If the program does terminal interaction, make it output a short
653 2c5a656a Andreas
 notice like this when it starts in an interactive mode:
654 2c5a656a Andreas
655 2c5a656a Andreas
     <program>  Copyright (C) <year>  <name of author>
656 2c5a656a Andreas
     This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
657 2c5a656a Andreas
     This is free software, and you are welcome to redistribute it
658 2c5a656a Andreas
     under certain conditions; type `show c' for details.
659 2c5a656a Andreas
660 2c5a656a Andreas
 The hypothetical commands `show w' and `show c' should show the appropriate
661 2c5a656a Andreas
 parts of the General Public License.  Of course, your program's commands
662 2c5a656a Andreas
 might be different; for a GUI interface, you would use an "about box".
663 2c5a656a Andreas
664 2c5a656a Andreas
   You should also get your employer (if you work as a programmer) or school,
665 2c5a656a Andreas
 if any, to sign a "copyright disclaimer" for the program, if necessary.
