3 <h2>Toybox is licensed under the terms of GPLv2.</h2> | |
4 | |
5 <p>The complete text of the General Public License version 2 is included in the | |
6 file LICENSE in each source tarball. Version 2 is the only version of | |
7 this license which toybox is distributed under. (I.E. It doesn't have the | |
8 strange "or later" dual license some projects have.)</p> | |
9 | |
10 <h2>Clarifications</h2> | |
11 | |
12 <p>The GPL is a bit old and crufty in places, but it's still the best open | |
13 source license there is, and lots of source code (like the Linux kernel) is | |
14 distributed under it. Lots of de facto interpretations have sprung up to deal | |
15 with things like the fact that it predates the internet service provider | |
16 industry. Nothing in the rest of this page changes the actual license, so you | |
17 can ignore the rest of this page if you're happy with a strict reading of | |
18 GPLv2. But just to be clear, here's how the authors of this project are | |
19 interpreting the sucker where it says something stupid.</p> | |
20 | |
21 <p>Section 1: <b>You have permission to rephrase the license notice on | |
22 individual source files.</b> This doesn't mean you can change what license the | |
23 code is under, or that you can remove other people's copyright notices. You | |
24 certainly can't change the test of the GPL itself. What it means is that if | |
25 you use this code in a project that distributes source in zip files instead of | |
26 tarballs, or your package's copy of the GPLv2 text isn't in a file called | |
27 "LICENSE", it's silly to preserve an obsolete notice verbatim and add some | |
28 kind of "correction" after the old notice.</p> | |
29 | |
30 <p>Some lawyers seem to think a strict reading of GPLv2 section 1 (and later | |
31 sections including section 1 by reference) requires maintaining old notices in | |
32 perpetuity. Even if you had code that used to be dual licensed, but created | |
33 a derived work that's just under one of the two licenses, so the old license | |
34 notice is not just strange or misleading but actually incorrect for the new | |
35 file. (For example, splicing GPLv2 only code into a dual "GPLv2 or later" | |
36 project produces a result that can be distributed under the terms of GPLv2, | |
37 but not GPLv3. The result cannot be distributed under the "or later" part, | |
38 so a license notice saying it could is factually wrong.)</p> | |
39 | |
40 <p>I don't know if we're ever going to put any dual licensed code into the tree, | |
41 but I want to head that one off now. The actual license text is the important | |
42 thing, the per-file notice is a courtesy.</p> | |
43 | |
44 <p>Section 2: <b>We don't put the change history in comments in the source | |
45 code, we put it in our source control system.</b> We have source control for a | |
46 reason. That's where this information belongs, and that's where we put it. | |
47 It's world readable on the web, and you can download a snapshot of the whole | |
48 repository if you like. The GPL predates modern source control systems, but | |
49 this project does not.</p> | |
50 | |
51 <p>Section 3: <b>We distribute source code through the internet.</b> If | |
52 your "written offer" includes a URL, and the source code remains anonymously | |
53 downloadable at that location for three years after you stop distributing | |
54 binaries, life is good as far as we're concerned. (No, you can't encrypt it, | |
55 or require a login, or otherwise be slimy bastards acting in bad faith. We'll | |
56 come after you if you're not satisfying the terms of the license, this is just | |
57 talking about how you can satisfy those terms without having to mail physical | |
58 media. Most people are already doing it this way.)</p> | |
59 | |
60 <p>Also, <a href="http://software.newsforge.com/article.pl?sid=06/06/23/1728205&tid=150">what the FSF did to Mepis</a> was inexcusable. (Further discussed | |
61 in <a href="http://www.busybox.net/lists/busybox/2006-June/022797.html">this | |
62 thread</a>.) Mepis partnered with Ubuntu, put out a press release quoting | |
63 Ubuntu's founder about how cool the partnership was, and then pointed to | |
64 Ubuntu's source repository for packages it was using unmodified Ubuntu versions | |
65 of. As far as we're concerned, Mepis didn't do anything wrong, and the FSF | |
66 was a bully. The FSF was wrong when it tried to make an example out of a | |
67 company that was acting in good faith.</p> | |
68 | |
69 <p>To make sure the FSF doesn't pick on anyone else against our wishes, we're | |
70 clarifying that if you didn't modify the source code, and the binaries you're | |
71 distributing can be entirely regenerated from a public upstream source, | |
72 pointing to that upstream source in good faith is good enough for us, as long | |
73 as they don't mind the extra bandwidth and the correct source code stays | |
74 available at that location for the duration of your responsiblity to | |
75 redistribute source.</p> | |
76 | |
77 <p>This doesn't mean it's fair for a Fortune 500 company to point millions of | |
78 people at somebody's home DSL line (certainly not without asking first). | |
79 And if the source that's available there isn't the complete source you used | |
80 to produce your binaries, you haven't fulfilled your obligations either. | |
81 And if the code stops being available at that location, you're not off the | |
82 hook and have to find a new location or put up your own mirror. And obviously | |
83 it has to be the _right_ source code (if you modified it, we want the patch, | |
84 and claiming you didn't modify it when you actually did is fraud).</p> | |
85 | |
86 <p>This is not a "get out of jail free" card: It's still your responsibility to | |
87 make the source available. We're just saying you can reasonably delegate to | |
88 something like Sourceforge or ibilbio and as long as everyone who wants the | |
89 source can get it, we're happy. If the site you point to objects or goes down, | |
90 responsibility obviously reverts to you.</p> | |
91 | |
92 <p>But if this project needs mirrors, we'll _ask_. (Most likely we'll ask | |
93 someone like sourceforge, OSL, ISC, ibiblio, archive.org...)</p> | |
94 | |
95 <p>Section 9: <b>Does not apply to this project.</b> We're specifying the | |
96 version, it's version 2. There is no "or later versions" clause to require | |
97 interpreting. | |

101 GNU GENERAL PUBLIC LICENSE | |
102 Version 2, June 1991 | |
103 | |
104 Copyright (C) 1989, 1991 Free Software Foundation, Inc. | |
105 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA | |
106 Everyone is permitted to copy and distribute verbatim copies | |
107 of this license document, but changing it is not allowed. | |
108 | |
109 Preamble | |
110 | |
111 The licenses for most software are designed to take away your | |
112 freedom to share and change it. By contrast, the GNU General Public | |
113 License is intended to guarantee your freedom to share and change free | |
114 software--to make sure the software is free for all its users. This | |
115 General Public License applies to most of the Free Software | |
116 Foundation's software and to any other program whose authors commit to | |
117 using it. (Some other Free Software Foundation software is covered by | |
118 the GNU Library General Public License instead.) You can apply it to | |
119 your programs, too. | |
120 | |
121 When we speak of free software, we are referring to freedom, not | |
122 price. Our General Public Licenses are designed to make sure that you | |
123 have the freedom to distribute copies of free software (and charge for | |
124 this service if you wish), that you receive source code or can get it | |
125 if you want it, that you can change the software or use pieces of it | |
126 in new free programs; and that you know you can do these things. | |
127 | |
128 To protect your rights, we need to make restrictions that forbid | |
129 anyone to deny you these rights or to ask you to surrender the rights. | |
130 These restrictions translate to certain responsibilities for you if you | |
131 distribute copies of the software, or if you modify it. | |
132 | |
133 For example, if you distribute copies of such a program, whether | |
134 gratis or for a fee, you must give the recipients all the rights that | |
135 you have. You must make sure that they, too, receive or can get the | |
136 source code. And you must show them these terms so they know their | |
137 rights. | |
138 | |
139 We protect your rights with two steps: (1) copyright the software, and | |
140 (2) offer you this license which gives you legal permission to copy, | |
141 distribute and/or modify the software. | |
142 | |
143 Also, for each author's protection and ours, we want to make certain | |
144 that everyone understands that there is no warranty for this free | |
145 software. If the software is modified by someone else and passed on, we | |
146 want its recipients to know that what they have is not the original, so | |
147 that any problems introduced by others will not reflect on the original | |
148 authors' reputations. | |
149 | |
150 Finally, any free program is threatened constantly by software | |
151 patents. We wish to avoid the danger that redistributors of a free | |
152 program will individually obtain patent licenses, in effect making the | |
153 program proprietary. To prevent this, we have made it clear that any | |
154 patent must be licensed for everyone's free use or not licensed at all. | |
155 | |
156 The precise terms and conditions for copying, distribution and | |
157 modification follow. | |
158 | |
159 GNU GENERAL PUBLIC LICENSE | |
160 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION | |
161 | |
162 0. This License applies to any program or other work which contains | |
163 a notice placed by the copyright holder saying it may be distributed | |
164 under the terms of this General Public License. The "Program", below, | |
165 refers to any such program or work, and a "work based on the Program" | |
166 means either the Program or any derivative work under copyright law: | |
167 that is to say, a work containing the Program or a portion of it, | |
168 either verbatim or with modifications and/or translated into another | |
169 language. (Hereinafter, translation is included without limitation in | |
170 the term "modification".) Each licensee is addressed as "you". | |
171 | |
172 Activities other than copying, distribution and modification are not | |
173 covered by this License; they are outside its scope. The act of | |
174 running the Program is not restricted, and the output from the Program | |
175 is covered only if its contents constitute a work based on the | |
176 Program (independent of having been made by running the Program). | |
177 Whether that is true depends on what the Program does. | |
178 | |
179 1. You may copy and distribute verbatim copies of the Program's | |
180 source code as you receive it, in any medium, provided that you | |
181 conspicuously and appropriately publish on each copy an appropriate | |
182 copyright notice and disclaimer of warranty; keep intact all the | |
183 notices that refer to this License and to the absence of any warranty; | |
184 and give any other recipients of the Program a copy of this License | |
185 along with the Program. | |
186 | |
187 You may charge a fee for the physical act of transferring a copy, and | |
188 you may at your option offer warranty protection in exchange for a fee. | |
189 | |
190 2. You may modify your copy or copies of the Program or any portion | |
191 of it, thus forming a work based on the Program, and copy and | |
192 distribute such modifications or work under the terms of Section 1 | |
193 above, provided that you also meet all of these conditions: | |
194 | |
195 a) You must cause the modified files to carry prominent notices | |
196 stating that you changed the files and the date of any change. | |
197 | |
198 b) You must cause any work that you distribute or publish, that in | |
199 whole or in part contains or is derived from the Program or any | |
200 part thereof, to be licensed as a whole at no charge to all third | |
201 parties under the terms of this License. | |
202 | |
203 c) If the modified program normally reads commands interactively | |
204 when run, you must cause it, when started running for such | |
205 interactive use in the most ordinary way, to print or display an | |
206 announcement including an appropriate copyright notice and a | |
207 notice that there is no warranty (or else, saying that you provide | |
208 a warranty) and that users may redistribute the program under | |
209 these conditions, and telling the user how to view a copy of this | |
210 License. (Exception: if the Program itself is interactive but | |
211 does not normally print such an announcement, your work based on | |
212 the Program is not required to print an announcement.) | |
213 | |
214 These requirements apply to the modified work as a whole. If | |
215 identifiable sections of that work are not derived from the Program, | |
216 and can be reasonably considered independent and separate works in | |
217 themselves, then this License, and its terms, do not apply to those | |
218 sections when you distribute them as separate works. But when you | |
219 distribute the same sections as part of a whole which is a work based | |
220 on the Program, the distribution of the whole must be on the terms of | |
221 this License, whose permissions for other licensees extend to the | |
222 entire whole, and thus to each and every part regardless of who wrote it. | |
223 | |
224 Thus, it is not the intent of this section to claim rights or contest | |
225 your rights to work written entirely by you; rather, the intent is to | |
226 exercise the right to control the distribution of derivative or | |
227 collective works based on the Program. | |
228 | |
229 In addition, mere aggregation of another work not based on the Program | |
230 with the Program (or with a work based on the Program) on a volume of | |
231 a storage or distribution medium does not bring the other work under | |
232 the scope of this License. | |
233 | |
234 3. You may copy and distribute the Program (or a work based on it, | |
235 under Section 2) in object code or executable form under the terms of | |
236 Sections 1 and 2 above provided that you also do one of the following: | |
237 | |
238 a) Accompany it with the complete corresponding machine-readable | |
239 source code, which must be distributed under the terms of Sections | |
240 1 and 2 above on a medium customarily used for software interchange; or, | |
241 | |
242 b) Accompany it with a written offer, valid for at least three | |
243 years, to give any third party, for a charge no more than your | |
244 cost of physically performing source distribution, a complete | |
245 machine-readable copy of the corresponding source code, to be | |
246 distributed under the terms of Sections 1 and 2 above on a medium | |
247 customarily used for software interchange; or, | |
248 | |
249 c) Accompany it with the information you received as to the offer | |
250 to distribute corresponding source code. (This alternative is | |
251 allowed only for noncommercial distribution and only if you | |
252 received the program in object code or executable form with such | |
253 an offer, in accord with Subsection b above.) | |
254 | |
255 The source code for a work means the preferred form of the work for | |
256 making modifications to it. For an executable work, complete source | |
257 code means all the source code for all modules it contains, plus any | |
258 associated interface definition files, plus the scripts used to | |
259 control compilation and installation of the executable. However, as a | |
260 special exception, the source code distributed need not include | |
261 anything that is normally distributed (in either source or binary | |
262 form) with the major components (compiler, kernel, and so on) of the | |
263 operating system on which the executable runs, unless that component | |
264 itself accompanies the executable. | |
265 | |
266 If distribution of executable or object code is made by offering | |
267 access to copy from a designated place, then offering equivalent | |
268 access to copy the source code from the same place counts as | |
269 distribution of the source code, even though third parties are not | |
270 compelled to copy the source along with the object code. | |
271 | |
272 4. You may not copy, modify, sublicense, or distribute the Program | |
273 except as expressly provided under this License. Any attempt | |
274 otherwise to copy, modify, sublicense or distribute the Program is | |
275 void, and will automatically terminate your rights under this License. | |
276 However, parties who have received copies, or rights, from you under | |
277 this License will not have their licenses terminated so long as such | |
278 parties remain in full compliance. | |
279 | |
280 5. You are not required to accept this License, since you have not | |
281 signed it. However, nothing else grants you permission to modify or | |
282 distribute the Program or its derivative works. These actions are | |
283 prohibited by law if you do not accept this License. Therefore, by | |
284 modifying or distributing the Program (or any work based on the | |
285 Program), you indicate your acceptance of this License to do so, and | |
286 all its terms and conditions for copying, distributing or modifying | |
287 the Program or works based on it. | |
288 | |
289 6. Each time you redistribute the Program (or any work based on the | |
290 Program), the recipient automatically receives a license from the | |
291 original licensor to copy, distribute or modify the Program subject to | |
292 these terms and conditions. You may not impose any further | |
293 restrictions on the recipients' exercise of the rights granted herein. | |
294 You are not responsible for enforcing compliance by third parties to | |
295 this License. | |
296 | |
297 7. If, as a consequence of a court judgment or allegation of patent | |
298 infringement or for any other reason (not limited to patent issues), | |
299 conditions are imposed on you (whether by court order, agreement or | |
300 otherwise) that contradict the conditions of this License, they do not | |
301 excuse you from the conditions of this License. If you cannot | |
302 distribute so as to satisfy simultaneously your obligations under this | |
303 License and any other pertinent obligations, then as a consequence you | |
304 may not distribute the Program at all. For example, if a patent | |
305 license would not permit royalty-free redistribution of the Program by | |
306 all those who receive copies directly or indirectly through you, then | |
307 the only way you could satisfy both it and this License would be to | |
308 refrain entirely from distribution of the Program. | |
309 | |
310 If any portion of this section is held invalid or unenforceable under | |
311 any particular circumstance, the balance of the section is intended to | |
312 apply and the section as a whole is intended to apply in other | |
313 circumstances. | |
314 | |
315 It is not the purpose of this section to induce you to infringe any | |
316 patents or other property right claims or to contest validity of any | |
317 such claims; this section has the sole purpose of protecting the | |
318 integrity of the free software distribution system, which is | |
319 implemented by public license practices. Many people have made | |
320 generous contributions to the wide range of software distributed | |
321 through that system in reliance on consistent application of that | |
322 system; it is up to the author/donor to decide if he or she is willing | |
323 to distribute software through any other system and a licensee cannot | |
324 impose that choice. | |
325 | |
326 This section is intended to make thoroughly clear what is believed to | |
327 be a consequence of the rest of this License. | |
328 | |
329 8. If the distribution and/or use of the Program is restricted in | |
330 certain countries either by patents or by copyrighted interfaces, the | |
331 original copyright holder who places the Program under this License | |
332 may add an explicit geographical distribution limitation excluding | |
333 those countries, so that distribution is permitted only in or among | |
334 countries not thus excluded. In such case, this License incorporates | |
335 the limitation as if written in the body of this License. | |
336 | |
337 9. The Free Software Foundation may publish revised and/or new versions | |
338 of the General Public License from time to time. Such new versions will | |
339 be similar in spirit to the present version, but may differ in detail to | |
340 address new problems or concerns. | |
341 | |
342 Each version is given a distinguishing version number. If the Program | |
343 specifies a version number of this License which applies to it and "any | |
344 later version", you have the option of following the terms and conditions | |
345 either of that version or of any later version published by the Free | |
346 Software Foundation. If the Program does not specify a version number of | |
347 this License, you may choose any version ever published by the Free Software | |
348 Foundation. | |
349 | |
350 10. If you wish to incorporate parts of the Program into other free | |
351 programs whose distribution conditions are different, write to the author | |
352 to ask for permission. For software which is copyrighted by the Free | |
353 Software Foundation, write to the Free Software Foundation; we sometimes | |
354 make exceptions for this. Our decision will be guided by the two goals | |
355 of preserving the free status of all derivatives of our free software and | |
356 of promoting the sharing and reuse of software generally. | |
357 | |
358 NO WARRANTY | |
359 | |
360 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY | |
361 FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN | |
362 OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES | |
363 PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED | |
364 OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF | |
365 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS | |
366 TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE | |
367 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, | |
368 REPAIR OR CORRECTION. | |
369 | |
370 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING | |
371 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR | |
372 REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, | |
373 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING | |
374 OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED | |
375 TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY | |
376 YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER | |
377 PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE | |
378 POSSIBILITY OF SUCH DAMAGES. | |
379 | |
380 END OF TERMS AND CONDITIONS | |
