1	+ GNU GENERAL PUBLIC LICENSE
2	+ Version 3, 29 June 2007
3	+
4	+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
5	+ Everyone is permitted to copy and distribute verbatim copies
6	+ of this license document, but changing it is not allowed.
7	+
8	+ Preamble
9	+
10	+ The GNU General Public License is a free, copyleft license for
11	+ software and other kinds of works.
12	+
13	+ The licenses for most software and other practical works are designed
14	+ to take away your freedom to share and change the works. By contrast,
15	+ the GNU General Public License is intended to guarantee your freedom to
16	+ share and change all versions of a program--to make sure it remains free
17	+ software for all its users. We, the Free Software Foundation, use the
18	+ GNU General Public License for most of our software; it applies also to
19	+ any other work released this way by its authors. You can apply it to
20	+ your programs, too.
21	+
22	+ When we speak of free software, we are referring to freedom, not
23	+ price. Our General Public Licenses are designed to make sure that you
24	+ have the freedom to distribute copies of free software (and charge for
25	+ them if you wish), that you receive source code or can get it if you
26	+ want it, that you can change the software or use pieces of it in new
27	+ free programs, and that you know you can do these things.
28	+
29	+ To protect your rights, we need to prevent others from denying you
30	+ these rights or asking you to surrender the rights. Therefore, you have
31	+ certain responsibilities if you distribute copies of the software, or if
32	+ you modify it: responsibilities to respect the freedom of others.
33	+
34	+ For example, if you distribute copies of such a program, whether
35	+ gratis or for a fee, you must pass on to the recipients the same
36	+ freedoms that you received. You must make sure that they, too, receive
37	+ or can get the source code. And you must show them these terms so they
38	+ know their rights.
39	+
40	+ Developers that use the GNU GPL protect your rights with two steps:
41	+ (1) assert copyright on the software, and (2) offer you this License
42	+ giving you legal permission to copy, distribute and/or modify it.
43	+
44	+ For the developers' and authors' protection, the GPL clearly explains
45	+ that there is no warranty for this free software. For both users' and
46	+ authors' sake, the GPL requires that modified versions be marked as
47	+ changed, so that their problems will not be attributed erroneously to
48	+ authors of previous versions.
49	+
50	+ Some devices are designed to deny users access to install or run
51	+ modified versions of the software inside them, although the manufacturer
52	+ can do so. This is fundamentally incompatible with the aim of
53	+ protecting users' freedom to change the software. The systematic
54	+ pattern of such abuse occurs in the area of products for individuals to
55	+ use, which is precisely where it is most unacceptable. Therefore, we
56	+ have designed this version of the GPL to prohibit the practice for those
57	+ products. If such problems arise substantially in other domains, we
58	+ stand ready to extend this provision to those domains in future versions
59	+ of the GPL, as needed to protect the freedom of users.
60	+
61	+ Finally, every program is threatened constantly by software patents.
62	+ States should not allow patents to restrict development and use of
63	+ software on general-purpose computers, but in those that do, we wish to
64	+ avoid the special danger that patents applied to a free program could
65	+ make it effectively proprietary. To prevent this, the GPL assures that
66	+ patents cannot be used to render the program non-free.
67	+
68	+ The precise terms and conditions for copying, distribution and
69	+ modification follow.
70	+
71	+ TERMS AND CONDITIONS
72	+
73	+ 0. Definitions.
74	+
75	+ "This License" refers to version 3 of the GNU General Public License.
76	+
77	+ "Copyright" also means copyright-like laws that apply to other kinds of
78	+ works, such as semiconductor masks.
79	+
80	+ "The Program" refers to any copyrightable work licensed under this
81	+ License. Each licensee is addressed as "you". "Licensees" and
82	+ "recipients" may be individuals or organizations.
83	+
84	+ To "modify" a work means to copy from or adapt all or part of the work
85	+ in a fashion requiring copyright permission, other than the making of an
86	+ exact copy. The resulting work is called a "modified version" of the
87	+ earlier work or a work "based on" the earlier work.
88	+
89	+ A "covered work" means either the unmodified Program or a work based
90	+ on the Program.
91	+
92	+ To "propagate" a work means to do anything with it that, without
93	+ permission, would make you directly or secondarily liable for
94	+ infringement under applicable copyright law, except executing it on a
95	+ computer or modifying a private copy. Propagation includes copying,
96	+ distribution (with or without modification), making available to the
97	+ public, and in some countries other activities as well.
98	+
99	+ To "convey" a work means any kind of propagation that enables other
100	+ parties to make or receive copies. Mere interaction with a user through
101	+ a computer network, with no transfer of a copy, is not conveying.
102	+
103	+ An interactive user interface displays "Appropriate Legal Notices"
104	+ to the extent that it includes a convenient and prominently visible
105	+ feature that (1) displays an appropriate copyright notice, and (2)
106	+ tells the user that there is no warranty for the work (except to the
107	+ extent that warranties are provided), that licensees may convey the
108	+ work under this License, and how to view a copy of this License. If
109	+ the interface presents a list of user commands or options, such as a
110	+ menu, a prominent item in the list meets this criterion.
111	+
112	+ 1. Source Code.
113	+
114	+ The "source code" for a work means the preferred form of the work
115	+ for making modifications to it. "Object code" means any non-source
116	+ form of a work.
117	+
118	+ A "Standard Interface" means an interface that either is an official
119	+ standard defined by a recognized standards body, or, in the case of
120	+ interfaces specified for a particular programming language, one that
121	+ is widely used among developers working in that language.
122	+
123	+ The "System Libraries" of an executable work include anything, other
124	+ than the work as a whole, that (a) is included in the normal form of
125	+ packaging a Major Component, but which is not part of that Major
126	+ Component, and (b) serves only to enable use of the work with that
127	+ Major Component, or to implement a Standard Interface for which an
128	+ implementation is available to the public in source code form. A
129	+ "Major Component", in this context, means a major essential component
130	+ (kernel, window system, and so on) of the specific operating system
131	+ (if any) on which the executable work runs, or a compiler used to
132	+ produce the work, or an object code interpreter used to run it.
133	+
134	+ The "Corresponding Source" for a work in object code form means all
135	+ the source code needed to generate, install, and (for an executable
136	+ work) run the object code and to modify the work, including scripts to
137	+ control those activities. However, it does not include the work's
138	+ System Libraries, or general-purpose tools or generally available free
139	+ programs which are used unmodified in performing those activities but
140	+ which are not part of the work. For example, Corresponding Source
141	+ includes interface definition files associated with source files for
142	+ the work, and the source code for shared libraries and dynamically
143	+ linked subprograms that the work is specifically designed to require,
144	+ such as by intimate data communication or control flow between those
145	+ subprograms and other parts of the work.
146	+
147	+ The Corresponding Source need not include anything that users
148	+ can regenerate automatically from other parts of the Corresponding
149	+ Source.
150	+
151	+ The Corresponding Source for a work in source code form is that
152	+ same work.
153	+
154	+ 2. Basic Permissions.
155	+
156	+ All rights granted under this License are granted for the term of
157	+ copyright on the Program, and are irrevocable provided the stated
158	+ conditions are met. This License explicitly affirms your unlimited
159	+ permission to run the unmodified Program. The output from running a
160	+ covered work is covered by this License only if the output, given its
161	+ content, constitutes a covered work. This License acknowledges your
162	+ rights of fair use or other equivalent, as provided by copyright law.
163	+
164	+ You may make, run and propagate covered works that you do not
165	+ convey, without conditions so long as your license otherwise remains
166	+ in force. You may convey covered works to others for the sole purpose
167	+ of having them make modifications exclusively for you, or provide you
168	+ with facilities for running those works, provided that you comply with
169	+ the terms of this License in conveying all material for which you do
170	+ not control copyright. Those thus making or running the covered works
171	+ for you must do so exclusively on your behalf, under your direction
172	+ and control, on terms that prohibit them from making any copies of
173	+ your copyrighted material outside their relationship with you.
174	+
175	+ Conveying under any other circumstances is permitted solely under
176	+ the conditions stated below. Sublicensing is not allowed; section 10
177	+ makes it unnecessary.
178	+
179	+ 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
180	+
181	+ No covered work shall be deemed part of an effective technological
182	+ measure under any applicable law fulfilling obligations under article
183	+ 11 of the WIPO copyright treaty adopted on 20 December 1996, or
184	+ similar laws prohibiting or restricting circumvention of such
185	+ measures.
186	+
187	+ When you convey a covered work, you waive any legal power to forbid
188	+ circumvention of technological measures to the extent such circumvention
189	+ is effected by exercising rights under this License with respect to
190	+ the covered work, and you disclaim any intention to limit operation or
191	+ modification of the work as a means of enforcing, against the work's
192	+ users, your or third parties' legal rights to forbid circumvention of
193	+ technological measures.
194	+
195	+ 4. Conveying Verbatim Copies.
196	+
197	+ You may convey verbatim copies of the Program's source code as you
198	+ receive it, in any medium, provided that you conspicuously and
199	+ appropriately publish on each copy an appropriate copyright notice;
200	+ keep intact all notices stating that this License and any
201	+ non-permissive terms added in accord with section 7 apply to the code;
202	+ keep intact all notices of the absence of any warranty; and give all
203	+ recipients a copy of this License along with the Program.
204	+
205	+ You may charge any price or no price for each copy that you convey,
206	+ and you may offer support or warranty protection for a fee.
207	+
208	+ 5. Conveying Modified Source Versions.
209	+
210	+ You may convey a work based on the Program, or the modifications to
211	+ produce it from the Program, in the form of source code under the
212	+ terms of section 4, provided that you also meet all of these conditions:
213	+
214	+ a) The work must carry prominent notices stating that you modified
215	+ it, and giving a relevant date.
216	+
217	+ b) The work must carry prominent notices stating that it is
218	+ released under this License and any conditions added under section
219	+ 7. This requirement modifies the requirement in section 4 to
220	+ "keep intact all notices".
221	+
222	+ c) You must license the entire work, as a whole, under this
223	+ License to anyone who comes into possession of a copy. This
224	+ License will therefore apply, along with any applicable section 7
225	+ additional terms, to the whole of the work, and all its parts,
226	+ regardless of how they are packaged. This License gives no
227	+ permission to license the work in any other way, but it does not
228	+ invalidate such permission if you have separately received it.
229	+
230	+ d) If the work has interactive user interfaces, each must display
231	+ Appropriate Legal Notices; however, if the Program has interactive
232	+ interfaces that do not display Appropriate Legal Notices, your
233	+ work need not make them do so.
234	+
235	+ A compilation of a covered work with other separate and independent
236	+ works, which are not by their nature extensions of the covered work,
237	+ and which are not combined with it such as to form a larger program,
238	+ in or on a volume of a storage or distribution medium, is called an
239	+ "aggregate" if the compilation and its resulting copyright are not
240	+ used to limit the access or legal rights of the compilation's users
241	+ beyond what the individual works permit. Inclusion of a covered work
242	+ in an aggregate does not cause this License to apply to the other
243	+ parts of the aggregate.
244	+
245	+ 6. Conveying Non-Source Forms.
246	+
247	+ You may convey a covered work in object code form under the terms
248	+ of sections 4 and 5, provided that you also convey the
249	+ machine-readable Corresponding Source under the terms of this License,
250	+ in one of these ways:
251	+
252	+ a) Convey the object code in, or embodied in, a physical product
253	+ (including a physical distribution medium), accompanied by the
254	+ Corresponding Source fixed on a durable physical medium
255	+ customarily used for software interchange.
256	+
257	+ b) Convey the object code in, or embodied in, a physical product
258	+ (including a physical distribution medium), accompanied by a
259	+ written offer, valid for at least three years and valid for as
260	+ long as you offer spare parts or customer support for that product
261	+ model, to give anyone who possesses the object code either (1) a
262	+ copy of the Corresponding Source for all the software in the
263	+ product that is covered by this License, on a durable physical
264	+ medium customarily used for software interchange, for a price no
265	+ more than your reasonable cost of physically performing this
266	+ conveying of source, or (2) access to copy the
267	+ Corresponding Source from a network server at no charge.
268	+
269	+ c) Convey individual copies of the object code with a copy of the
270	+ written offer to provide the Corresponding Source. This
271	+ alternative is allowed only occasionally and noncommercially, and
272	+ only if you received the object code with such an offer, in accord
273	+ with subsection 6b.
274	+
275	+ d) Convey the object code by offering access from a designated
276	+ place (gratis or for a charge), and offer equivalent access to the
277	+ Corresponding Source in the same way through the same place at no
278	+ further charge. You need not require recipients to copy the
279	+ Corresponding Source along with the object code. If the place to
280	+ copy the object code is a network server, the Corresponding Source
281	+ may be on a different server (operated by you or a third party)
282	+ that supports equivalent copying facilities, provided you maintain
283	+ clear directions next to the object code saying where to find the
284	+ Corresponding Source. Regardless of what server hosts the
285	+ Corresponding Source, you remain obligated to ensure that it is
286	+ available for as long as needed to satisfy these requirements.
287	+
288	+ e) Convey the object code using peer-to-peer transmission, provided
289	+ you inform other peers where the object code and Corresponding
290	+ Source of the work are being offered to the general public at no
291	+ charge under subsection 6d.
292	+
293	+ A separable portion of the object code, whose source code is excluded
294	+ from the Corresponding Source as a System Library, need not be
295	+ included in conveying the object code work.
296	+
297	+ A "User Product" is either (1) a "consumer product", which means any
298	+ tangible personal property which is normally used for personal, family,
299	+ or household purposes, or (2) anything designed or sold for incorporation
300	+ into a dwelling. In determining whether a product is a consumer product,
301	+ doubtful cases shall be resolved in favor of coverage. For a particular
302	+ product received by a particular user, "normally used" refers to a
303	+ typical or common use of that class of product, regardless of the status
304	+ of the particular user or of the way in which the particular user
305	+ actually uses, or expects or is expected to use, the product. A product
306	+ is a consumer product regardless of whether the product has substantial
307	+ commercial, industrial or non-consumer uses, unless such uses represent
308	+ the only significant mode of use of the product.
309	+
310	+ "Installation Information" for a User Product means any methods,
311	+ procedures, authorization keys, or other information required to install
312	+ and execute modified versions of a covered work in that User Product from
313	+ a modified version of its Corresponding Source. The information must
314	+ suffice to ensure that the continued functioning of the modified object
315	+ code is in no case prevented or interfered with solely because
316	+ modification has been made.
317	+
318	+ If you convey an object code work under this section in, or with, or
319	+ specifically for use in, a User Product, and the conveying occurs as
320	+ part of a transaction in which the right of possession and use of the
321	+ User Product is transferred to the recipient in perpetuity or for a
322	+ fixed term (regardless of how the transaction is characterized), the
323	+ Corresponding Source conveyed under this section must be accompanied
324	+ by the Installation Information. But this requirement does not apply
325	+ if neither you nor any third party retains the ability to install
326	+ modified object code on the User Product (for example, the work has
327	+ been installed in ROM).
328	+
329	+ The requirement to provide Installation Information does not include a
330	+ requirement to continue to provide support service, warranty, or updates
331	+ for a work that has been modified or installed by the recipient, or for
332	+ the User Product in which it has been modified or installed. Access to a
333	+ network may be denied when the modification itself materially and
334	+ adversely affects the operation of the network or violates the rules and
335	+ protocols for communication across the network.
336	+
337	+ Corresponding Source conveyed, and Installation Information provided,
338	+ in accord with this section must be in a format that is publicly
339	+ documented (and with an implementation available to the public in
340	+ source code form), and must require no special password or key for
341	+ unpacking, reading or copying.
342	+
343	+ 7. Additional Terms.
344	+
345	+ "Additional permissions" are terms that supplement the terms of this
346	+ License by making exceptions from one or more of its conditions.
347	+ Additional permissions that are applicable to the entire Program shall
348	+ be treated as though they were included in this License, to the extent
349	+ that they are valid under applicable law. If additional permissions
350	+ apply only to part of the Program, that part may be used separately
351	+ under those permissions, but the entire Program remains governed by
352	+ this License without regard to the additional permissions.
353	+
354	+ When you convey a copy of a covered work, you may at your option
355	+ remove any additional permissions from that copy, or from any part of
356	+ it. (Additional permissions may be written to require their own
357	+ removal in certain cases when you modify the work.) You may place
358	+ additional permissions on material, added by you to a covered work,
359	+ for which you have or can give appropriate copyright permission.
360	+
361	+ Notwithstanding any other provision of this License, for material you
362	+ add to a covered work, you may (if authorized by the copyright holders of
363	+ that material) supplement the terms of this License with terms:
364	+
365	+ a) Disclaiming warranty or limiting liability differently from the
366	+ terms of sections 15 and 16 of this License; or
367	+
368	+ b) Requiring preservation of specified reasonable legal notices or
369	+ author attributions in that material or in the Appropriate Legal
370	+ Notices displayed by works containing it; or
371	+
372	+ c) Prohibiting misrepresentation of the origin of that material, or
373	+ requiring that modified versions of such material be marked in
374	+ reasonable ways as different from the original version; or
375	+
376	+ d) Limiting the use for publicity purposes of names of licensors or
377	+ authors of the material; or
378	+
379	+ e) Declining to grant rights under trademark law for use of some
380	+ trade names, trademarks, or service marks; or
381	+
382	+ f) Requiring indemnification of licensors and authors of that
383	+ material by anyone who conveys the material (or modified versions of
384	+ it) with contractual assumptions of liability to the recipient, for
385	+ any liability that these contractual assumptions directly impose on
386	+ those licensors and authors.
387	+
388	+ All other non-permissive additional terms are considered "further
389	+ restrictions" within the meaning of section 10. If the Program as you
390	+ received it, or any part of it, contains a notice stating that it is
391	+ governed by this License along with a term that is a further
392	+ restriction, you may remove that term. If a license document contains
393	+ a further restriction but permits relicensing or conveying under this
394	+ License, you may add to a covered work material governed by the terms
395	+ of that license document, provided that the further restriction does
396	+ not survive such relicensing or conveying.
397	+
398	+ If you add terms to a covered work in accord with this section, you
399	+ must place, in the relevant source files, a statement of the
400	+ additional terms that apply to those files, or a notice indicating
401	+ where to find the applicable terms.
402	+
403	+ Additional terms, permissive or non-permissive, may be stated in the
404	+ form of a separately written license, or stated as exceptions;
405	+ the above requirements apply either way.
406	+
407	+ 8. Termination.
408	+
409	+ You may not propagate or modify a covered work except as expressly
410	+ provided under this License. Any attempt otherwise to propagate or
411	+ modify it is void, and will automatically terminate your rights under
412	+ this License (including any patent licenses granted under the third
413	+ paragraph of section 11).
414	+
415	+ However, if you cease all violation of this License, then your
416	+ license from a particular copyright holder is reinstated (a)
417	+ provisionally, unless and until the copyright holder explicitly and
418	+ finally terminates your license, and (b) permanently, if the copyright
419	+ holder fails to notify you of the violation by some reasonable means
420	+ prior to 60 days after the cessation.
421	+
422	+ Moreover, your license from a particular copyright holder is
423	+ reinstated permanently if the copyright holder notifies you of the
424	+ violation by some reasonable means, this is the first time you have
425	+ received notice of violation of this License (for any work) from that
426	+ copyright holder, and you cure the violation prior to 30 days after
427	+ your receipt of the notice.
428	+
429	+ Termination of your rights under this section does not terminate the
430	+ licenses of parties who have received copies or rights from you under
431	+ this License. If your rights have been terminated and not permanently
432	+ reinstated, you do not qualify to receive new licenses for the same
433	+ material under section 10.
434	+
435	+ 9. Acceptance Not Required for Having Copies.
436	+
437	+ You are not required to accept this License in order to receive or
438	+ run a copy of the Program. Ancillary propagation of a covered work
439	+ occurring solely as a consequence of using peer-to-peer transmission
440	+ to receive a copy likewise does not require acceptance. However,
441	+ nothing other than this License grants you permission to propagate or
442	+ modify any covered work. These actions infringe copyright if you do
443	+ not accept this License. Therefore, by modifying or propagating a
444	+ covered work, you indicate your acceptance of this License to do so.
445	+
446	+ 10. Automatic Licensing of Downstream Recipients.
447	+
448	+ Each time you convey a covered work, the recipient automatically
449	+ receives a license from the original licensors, to run, modify and
450	+ propagate that work, subject to this License. You are not responsible
451	+ for enforcing compliance by third parties with this License.
452	+
453	+ An "entity transaction" is a transaction transferring control of an
454	+ organization, or substantially all assets of one, or subdividing an
455	+ organization, or merging organizations. If propagation of a covered
456	+ work results from an entity transaction, each party to that
457	+ transaction who receives a copy of the work also receives whatever
458	+ licenses to the work the party's predecessor in interest had or could
459	+ give under the previous paragraph, plus a right to possession of the
460	+ Corresponding Source of the work from the predecessor in interest, if
461	+ the predecessor has it or can get it with reasonable efforts.
462	+
463	+ You may not impose any further restrictions on the exercise of the
464	+ rights granted or affirmed under this License. For example, you may
465	+ not impose a license fee, royalty, or other charge for exercise of
466	+ rights granted under this License, and you may not initiate litigation
467	+ (including a cross-claim or counterclaim in a lawsuit) alleging that
468	+ any patent claim is infringed by making, using, selling, offering for
469	+ sale, or importing the Program or any portion of it.
470	+
471	+ 11. Patents.
472	+
473	+ A "contributor" is a copyright holder who authorizes use under this
474	+ License of the Program or a work on which the Program is based. The
475	+ work thus licensed is called the contributor's "contributor version".
476	+
477	+ A contributor's "essential patent claims" are all patent claims
478	+ owned or controlled by the contributor, whether already acquired or
479	+ hereafter acquired, that would be infringed by some manner, permitted
480	+ by this License, of making, using, or selling its contributor version,
481	+ but do not include claims that would be infringed only as a
482	+ consequence of further modification of the contributor version. For
483	+ purposes of this definition, "control" includes the right to grant
484	+ patent sublicenses in a manner consistent with the requirements of
485	+ this License.
486	+
487	+ Each contributor grants you a non-exclusive, worldwide, royalty-free
488	+ patent license under the contributor's essential patent claims, to
489	+ make, use, sell, offer for sale, import and otherwise run, modify and
490	+ propagate the contents of its contributor version.
491	+
492	+ In the following three paragraphs, a "patent license" is any express
493	+ agreement or commitment, however denominated, not to enforce a patent
494	+ (such as an express permission to practice a patent or covenant not to
495	+ sue for patent infringement). To "grant" such a patent license to a
496	+ party means to make such an agreement or commitment not to enforce a
497	+ patent against the party.
498	+
499	+ If you convey a covered work, knowingly relying on a patent license,
500	+ and the Corresponding Source of the work is not available for anyone
501	+ to copy, free of charge and under the terms of this License, through a
502	+ publicly available network server or other readily accessible means,
503	+ then you must either (1) cause the Corresponding Source to be so
504	+ available, or (2) arrange to deprive yourself of the benefit of the
505	+ patent license for this particular work, or (3) arrange, in a manner
506	+ consistent with the requirements of this License, to extend the patent
507	+ license to downstream recipients. "Knowingly relying" means you have
508	+ actual knowledge that, but for the patent license, your conveying the
509	+ covered work in a country, or your recipient's use of the covered work
510	+ in a country, would infringe one or more identifiable patents in that
511	+ country that you have reason to believe are valid.
512	+
513	+ If, pursuant to or in connection with a single transaction or
514	+ arrangement, you convey, or propagate by procuring conveyance of, a
515	+ covered work, and grant a patent license to some of the parties
516	+ receiving the covered work authorizing them to use, propagate, modify
517	+ or convey a specific copy of the covered work, then the patent license
518	+ you grant is automatically extended to all recipients of the covered
519	+ work and works based on it.
520	+
521	+ A patent license is "discriminatory" if it does not include within
522	+ the scope of its coverage, prohibits the exercise of, or is
523	+ conditioned on the non-exercise of one or more of the rights that are
524	+ specifically granted under this License. You may not convey a covered
525	+ work if you are a party to an arrangement with a third party that is
526	+ in the business of distributing software, under which you make payment
527	+ to the third party based on the extent of your activity of conveying
528	+ the work, and under which the third party grants, to any of the
529	+ parties who would receive the covered work from you, a discriminatory
530	+ patent license (a) in connection with copies of the covered work
531	+ conveyed by you (or copies made from those copies), or (b) primarily
532	+ for and in connection with specific products or compilations that
533	+ contain the covered work, unless you entered into that arrangement,
534	+ or that patent license was granted, prior to 28 March 2007.
535	+
536	+ Nothing in this License shall be construed as excluding or limiting
537	+ any implied license or other defenses to infringement that may
538	+ otherwise be available to you under applicable patent law.
539	+
540	+ 12. No Surrender of Others' Freedom.
541	+
542	+ If conditions are imposed on you (whether by court order, agreement or
543	+ otherwise) that contradict the conditions of this License, they do not
544	+ excuse you from the conditions of this License. If you cannot convey a
545	+ covered work so as to satisfy simultaneously your obligations under this
546	+ License and any other pertinent obligations, then as a consequence you may
547	+ not convey it at all. For example, if you agree to terms that obligate you
548	+ to collect a royalty for further conveying from those to whom you convey
549	+ the Program, the only way you could satisfy both those terms and this
550	+ License would be to refrain entirely from conveying the Program.
551	+
552	+ 13. Use with the GNU Affero General Public License.
553	+
554	+ Notwithstanding any other provision of this License, you have
555	+ permission to link or combine any covered work with a work licensed
556	+ under version 3 of the GNU Affero General Public License into a single
557	+ combined work, and to convey the resulting work. The terms of this
558	+ License will continue to apply to the part which is the covered work,
559	+ but the special requirements of the GNU Affero General Public License,
560	+ section 13, concerning interaction through a network will apply to the
561	+ combination as such.
562	+
563	+ 14. Revised Versions of this License.
564	+
565	+ The Free Software Foundation may publish revised and/or new versions of
566	+ the GNU General Public License from time to time. Such new versions will
567	+ be similar in spirit to the present version, but may differ in detail to
568	+ address new problems or concerns.
569	+
570	+ Each version is given a distinguishing version number. If the
571	+ Program specifies that a certain numbered version of the GNU General
572	+ Public License "or any later version" applies to it, you have the
573	+ option of following the terms and conditions either of that numbered
574	+ version or of any later version published by the Free Software
575	+ Foundation. If the Program does not specify a version number of the
576	+ GNU General Public License, you may choose any version ever published
577	+ by the Free Software Foundation.
578	+
579	+ If the Program specifies that a proxy can decide which future
580	+ versions of the GNU General Public License can be used, that proxy's
581	+ public statement of acceptance of a version permanently authorizes you
582	+ to choose that version for the Program.
583	+
584	+ Later license versions may give you additional or different
585	+ permissions. However, no additional obligations are imposed on any
586	+ author or copyright holder as a result of your choosing to follow a
587	+ later version.
588	+
589	+ 15. Disclaimer of Warranty.
590	+
591	+ THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
592	+ APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
593	+ HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
594	+ OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
595	+ THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
596	+ PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
597	+ IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
598	+ ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
599	+
600	+ 16. Limitation of Liability.
601	+
602	+ IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
603	+ WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
604	+ THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
605	+ GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
606	+ USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
607	+ DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
608	+ PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
609	+ EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
610	+ SUCH DAMAGES.
611	+
612	+ 17. Interpretation of Sections 15 and 16.
613	+
614	+ If the disclaimer of warranty and limitation of liability provided
615	+ above cannot be given local legal effect according to their terms,
616	+ reviewing courts shall apply local law that most closely approximates
617	+ an absolute waiver of all civil liability in connection with the
618	+ Program, unless a warranty or assumption of liability accompanies a
619	+ copy of the Program in return for a fee.
620	+
621	+ END OF TERMS AND CONDITIONS
622	+
623	+ How to Apply These Terms to Your New Programs
624	+
625	+ If you develop a new program, and you want it to be of the greatest
626	+ possible use to the public, the best way to achieve this is to make it
627	+ free software which everyone can redistribute and change under these terms.
628	+
629	+ To do so, attach the following notices to the program. It is safest
630	+ to attach them to the start of each source file to most effectively
631	+ state the exclusion of warranty; and each file should have at least
632	+ the "copyright" line and a pointer to where the full notice is found.
633	+
634	+ <one line to give the program's name and a brief idea of what it does.>
635	+ Copyright (C) <year> <name of author>
636	+
637	+ This program is free software: you can redistribute it and/or modify
638	+ it under the terms of the GNU General Public License as published by
639	+ the Free Software Foundation, either version 3 of the License, or
640	+ (at your option) any later version.
641	+
642	+ This program is distributed in the hope that it will be useful,
643	+ but WITHOUT ANY WARRANTY; without even the implied warranty of
644	+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
645	+ GNU General Public License for more details.
646	+
647	+ You should have received a copy of the GNU General Public License
648	+ along with this program. If not, see <http://www.gnu.org/licenses/>.
649	+
650	+ Also add information on how to contact you by electronic and paper mail.
651	+
652	+ If the program does terminal interaction, make it output a short
653	+ notice like this when it starts in an interactive mode:
654	+
655	+ <program> Copyright (C) <year> <name of author>
656	+ This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
657	+ This is free software, and you are welcome to redistribute it
658	+ under certain conditions; type `show c' for details.
659	+
660	+ The hypothetical commands `show w' and `show c' should show the appropriate
661	+ parts of the General Public License. Of course, your program's commands
662	+ might be different; for a GUI interface, you would use an "about box".
663	+
664	+ You should also get your employer (if you work as a programmer) or school,
665	+ if any, to sign a "copyright disclaimer" for the program, if necessary.
666	+ For more information on this, and how to apply and follow the GNU GPL, see
667	+ <http://www.gnu.org/licenses/>.
668	+
669	+ The GNU General Public License does not permit incorporating your program
670	+ into proprietary programs. If your program is a subroutine library, you
671	+ may consider it more useful to permit linking proprietary applications with
672	+ the library. If this is what you want to do, use the GNU Lesser General
673	+ Public License instead of this License. But first, please read
674	+ <http://www.gnu.org/philosophy/why-not-lgpl.html>.

10	+
11	+ Apply fine-grained discounts to items in the shopping cart, dependently on ordered quantity and on concrete product.
12	+
13	+ == Description ==
14	+
15	+ WooCommerce Bulk Discount Plugin makes possible to apply fine-grained discounts
16	+ to items in the shopping cart, dependently on ordered quantity and on concrete
17	+ product.
18	+
19	+ The plugin works with WooCommerce versions 2.0.x.
20	+
21	+ Let us examine some examples of usage.
22	+
23	+ * You may want to feature such discount policy in your store that if a customer
24	+ orders more than 5 items of some product, he/she would pay the price of this order
25	+ line lowered by 10%.
26	+
27	+ * Or you may want different policy, for example offering 5% discount if customer
28	+ orders more than 10 items of a product and 10% discount if he/she orders more than
29	+ 20 items.
30	+
31	+ The settings for discounts are simple yet extensive, allowing wide range of discount
32	+ policies to be adopted across your store.
33	+
34	+ == Installation ==
35	+
36	+ 1. Download the latest version and extract it in the /wp-content/plugins/ directory
37	+ 2. Activate the plugin through the 'Plugins' menu in WordPress
38	+
39	+ Once the plugin is activated, you can use it as follows:
40	+
41	+ 1. First navigate to WooCommerce settings. Under the Bulk Discount tab, find the global
42	+ configuration for bulk discounts. Make sure "Bulk Discount enabled" is checked and optionally
43	+ fill information about discounts which will be visible on cart page. You can include HTML
44	+ markup in the text - you can, for instance, include a link to your page with discount
45	+ policy. In case you need the plugin to work well with product variations, make sure that the
46	+ "Treat product variations separately" option is unchecked. Save the settings.
47	+
48	+ 2. Navigate to Products and choose a product for which you want to create discount policy.
49	+ In Product Data panel, click Bulk Dicounts and optionally fill information about discount
50	+ which will be visible in product description.
51	+
52	+ 3. Click "Add discount line" button to create a policy. Quantity (min.) means minimal
53	+ number of ordered items so that the (second textbox) Discount applies. It is possible to
54	+ add up to five discount lines to fine-tune the discount setting.
55	+
56	+ == Frequently Asked Questions ==
57	+
58	+ = Are multiple discounts supported? How many levels of discounting may be applied? =
59	+
60	+ Yes, multiple discounts (related to single product) are supported. Currently one may set up
61	+ to 5 discount lines. That should be enough for reasonable fine-tuning of the discount.
62	+
63	+ = Is it possible to handle discount for product variations as a whole? =
64	+ Yes, in case you have several product variations in your store and you need to apply discount
65	+ to all the purchased variations, please upgrade to version 1.2 (or newer) of this plugin.
66	+ This behaviour can be disabled in Bulk Discount settings.
67	+
68	+ == Screenshots ==
69	+
70	+ 1. Enabling the plugin and setting information about discounts policy.
71	+ 2. Setting the discount lines. Often only one line is sufficient.
72	+
73	+ == Changelog ==
74	+
75	+ = 1.2 =
76	+ * (24 Aug 2013) Possibility to treat product variations as a whole when discounting.
77	+ * CSS changes.
78	+ * Show the applied discount in percents on hovering the item price in the cart.
79	+
80	+ = 1.1.1 =
81	+ * (21 Aug 2013) Plugin settings moved to separate tab under WooCommerce > Settings.
82	+ * CSS refined.
83	+ * code cleanup.
84	+ * more code comments added.
85	+
86	+ = 1.1 =
87	+ * (7 Jul 2013) resolved major issue of incorrect discount application in some cases.
88	+ * code optimization.
89	+ * cleaned up some code.
90	+
91	+ = 1.0.1 =
92	+ * (5 Jul 2013) cleaned up some code.
93	+
94	+ = 1.0 =
95	+ * Stable version.
96	+
97	+ == Upgrade Notice ==
98	+
99	+ = 1.2 =
100	+ Release with new features.
101	+
102	+ = 1.1.1 =
103	+ Maintenance release.
104	+
105	+ = 1.1 =
106	+ Important bugfix release. Upgrading recommended as soon as possible.
107	+
108	+ = 1.0.1 =
109	+ This version has minor change in code without any noticeable impact.
110	+
111	+ = 1.0 =
112	+ N/A.
113	+
114	+ == Example of setting a discount ==
115	+
116	+ Below is an example of setting a multiple discount for some product with three discount lines.
117	+
118	+ Example:
119	+
120	+ 1. Quantity (min.) = 3, Discount (%) = 5
121	+ 2. Quantity (min.) = 8, Discount (%) = 10
122	+ 3. Quantity (min.) = 15, Discount (%) = 15
123	+
124	+ If a customer ordered, say, 12 items of the product which costs $15 per item, the second
125	+ discount line would apply. The customer than pays 12 * 15 = 225 dollars in total minus
126	+ 10%, which yields $202.5. Note that this discount policy only applies to a concrete product - other
127	+ products may have their own (possibly different) discount policies.
