10 GNU General Public License for more details. 10
11 11 The licenses for most software are designed to take away your
12 For information on how to redistribute this software under 12 freedom to share and change it. By contrast, the GNU General Public
13 the terms of a license other than GNU General Public License 13 License is intended to guarantee your freedom to share and change free
14 contact TMate Software at support@hg4j.com 14 software--to make sure the software is free for all its users. This
15 General Public License applies to most of the Free Software
16 Foundation's software and to any other program whose authors commit to
17 using it. (Some other Free Software Foundation software is covered by
18 the GNU Lesser General Public License instead.) You can apply it to
19 your programs, too.
20
21 When we speak of free software, we are referring to freedom, not
22 price. Our General Public Licenses are designed to make sure that you
23 have the freedom to distribute copies of free software (and charge for
24 this service if you wish), that you receive source code or can get it
25 if you want it, that you can change the software or use pieces of it
26 in new free programs; and that you know you can do these things.
27
28 To protect your rights, we need to make restrictions that forbid
29 anyone to deny you these rights or to ask you to surrender the rights.
30 These restrictions translate to certain responsibilities for you if you
31 distribute copies of the software, or if you modify it.
32
33 For example, if you distribute copies of such a program, whether
34 gratis or for a fee, you must give the recipients all the rights that
35 you have. You must make sure that they, too, receive or can get the
36 source code. And you must show them these terms so they know their
37 rights.
38
39 We protect your rights with two steps: (1) copyright the software, and
40 (2) offer you this license which gives you legal permission to copy,
41 distribute and/or modify the software.
42
43 Also, for each author's protection and ours, we want to make certain
44 that everyone understands that there is no warranty for this free
45 software. If the software is modified by someone else and passed on, we
46 want its recipients to know that what they have is not the original, so
47 that any problems introduced by others will not reflect on the original
48 authors' reputations.
49
50 Finally, any free program is threatened constantly by software
51 patents. We wish to avoid the danger that redistributors of a free
52 program will individually obtain patent licenses, in effect making the
53 program proprietary. To prevent this, we have made it clear that any
54 patent must be licensed for everyone's free use or not licensed at all.
55
56 The precise terms and conditions for copying, distribution and
57 modification follow.
58
59 GNU GENERAL PUBLIC LICENSE
60 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
61
62 0. This License applies to any program or other work which contains
63 a notice placed by the copyright holder saying it may be distributed
64 under the terms of this General Public License. The "Program", below,
65 refers to any such program or work, and a "work based on the Program"
66 means either the Program or any derivative work under copyright law:
67 that is to say, a work containing the Program or a portion of it,
68 either verbatim or with modifications and/or translated into another
69 language. (Hereinafter, translation is included without limitation in
70 the term "modification".) Each licensee is addressed as "you".
71
72 Activities other than copying, distribution and modification are not
73 covered by this License; they are outside its scope. The act of
74 running the Program is not restricted, and the output from the Program
75 is covered only if its contents constitute a work based on the
76 Program (independent of having been made by running the Program).
77 Whether that is true depends on what the Program does.
78
79 1. You may copy and distribute verbatim copies of the Program's
80 source code as you receive it, in any medium, provided that you
81 conspicuously and appropriately publish on each copy an appropriate
82 copyright notice and disclaimer of warranty; keep intact all the
83 notices that refer to this License and to the absence of any warranty;
84 and give any other recipients of the Program a copy of this License
85 along with the Program.
86
87 You may charge a fee for the physical act of transferring a copy, and
88 you may at your option offer warranty protection in exchange for a fee.
89
90 2. You may modify your copy or copies of the Program or any portion
91 of it, thus forming a work based on the Program, and copy and
92 distribute such modifications or work under the terms of Section 1
93 above, provided that you also meet all of these conditions:
94
95 a) You must cause the modified files to carry prominent notices
96 stating that you changed the files and the date of any change.
97
98 b) You must cause any work that you distribute or publish, that in
99 whole or in part contains or is derived from the Program or any
100 part thereof, to be licensed as a whole at no charge to all third
101 parties under the terms of this License.
102
103 c) If the modified program normally reads commands interactively
104 when run, you must cause it, when started running for such
105 interactive use in the most ordinary way, to print or display an
106 announcement including an appropriate copyright notice and a
107 notice that there is no warranty (or else, saying that you provide
108 a warranty) and that users may redistribute the program under
109 these conditions, and telling the user how to view a copy of this
110 License. (Exception: if the Program itself is interactive but
111 does not normally print such an announcement, your work based on
112 the Program is not required to print an announcement.)
113
114 These requirements apply to the modified work as a whole. If
115 identifiable sections of that work are not derived from the Program,
116 and can be reasonably considered independent and separate works in
117 themselves, then this License, and its terms, do not apply to those
118 sections when you distribute them as separate works. But when you
119 distribute the same sections as part of a whole which is a work based
120 on the Program, the distribution of the whole must be on the terms of
121 this License, whose permissions for other licensees extend to the
122 entire whole, and thus to each and every part regardless of who wrote it.
123
124 Thus, it is not the intent of this section to claim rights or contest
125 your rights to work written entirely by you; rather, the intent is to
126 exercise the right to control the distribution of derivative or
127 collective works based on the Program.
128
129 In addition, mere aggregation of another work not based on the Program
130 with the Program (or with a work based on the Program) on a volume of
131 a storage or distribution medium does not bring the other work under
132 the scope of this License.
133
134 3. You may copy and distribute the Program (or a work based on it,
135 under Section 2) in object code or executable form under the terms of
136 Sections 1 and 2 above provided that you also do one of the following:
137
138 a) Accompany it with the complete corresponding machine-readable
139 source code, which must be distributed under the terms of Sections
140 1 and 2 above on a medium customarily used for software interchange; or,
141
142 b) Accompany it with a written offer, valid for at least three
143 years, to give any third party, for a charge no more than your
144 cost of physically performing source distribution, a complete
145 machine-readable copy of the corresponding source code, to be
146 distributed under the terms of Sections 1 and 2 above on a medium
147 customarily used for software interchange; or,
148
149 c) Accompany it with the information you received as to the offer
150 to distribute corresponding source code. (This alternative is
151 allowed only for noncommercial distribution and only if you
152 received the program in object code or executable form with such
153 an offer, in accord with Subsection b above.)
154
155 The source code for a work means the preferred form of the work for
156 making modifications to it. For an executable work, complete source
157 code means all the source code for all modules it contains, plus any
158 associated interface definition files, plus the scripts used to
159 control compilation and installation of the executable. However, as a
160 special exception, the source code distributed need not include
161 anything that is normally distributed (in either source or binary
162 form) with the major components (compiler, kernel, and so on) of the
163 operating system on which the executable runs, unless that component
164 itself accompanies the executable.
165
166 If distribution of executable or object code is made by offering
167 access to copy from a designated place, then offering equivalent
168 access to copy the source code from the same place counts as
169 distribution of the source code, even though third parties are not
170 compelled to copy the source along with the object code.
171
172 4. You may not copy, modify, sublicense, or distribute the Program
173 except as expressly provided under this License. Any attempt
174 otherwise to copy, modify, sublicense or distribute the Program is
175 void, and will automatically terminate your rights under this License.
176 However, parties who have received copies, or rights, from you under
177 this License will not have their licenses terminated so long as such
178 parties remain in full compliance.
179
180 5. You are not required to accept this License, since you have not
181 signed it. However, nothing else grants you permission to modify or
182 distribute the Program or its derivative works. These actions are
183 prohibited by law if you do not accept this License. Therefore, by
184 modifying or distributing the Program (or any work based on the
185 Program), you indicate your acceptance of this License to do so, and
186 all its terms and conditions for copying, distributing or modifying
187 the Program or works based on it.
188
189 6. Each time you redistribute the Program (or any work based on the
190 Program), the recipient automatically receives a license from the
191 original licensor to copy, distribute or modify the Program subject to
192 these terms and conditions. You may not impose any further
193 restrictions on the recipients' exercise of the rights granted herein.
194 You are not responsible for enforcing compliance by third parties to
195 this License.
196
197 7. If, as a consequence of a court judgment or allegation of patent
198 infringement or for any other reason (not limited to patent issues),
199 conditions are imposed on you (whether by court order, agreement or
200 otherwise) that contradict the conditions of this License, they do not
201 excuse you from the conditions of this License. If you cannot
202 distribute so as to satisfy simultaneously your obligations under this
203 License and any other pertinent obligations, then as a consequence you
204 may not distribute the Program at all. For example, if a patent
205 license would not permit royalty-free redistribution of the Program by
206 all those who receive copies directly or indirectly through you, then
207 the only way you could satisfy both it and this License would be to
208 refrain entirely from distribution of the Program.
209
210 If any portion of this section is held invalid or unenforceable under
211 any particular circumstance, the balance of the section is intended to
212 apply and the section as a whole is intended to apply in other
213 circumstances.
214
215 It is not the purpose of this section to induce you to infringe any
216 patents or other property right claims or to contest validity of any
217 such claims; this section has the sole purpose of protecting the
218 integrity of the free software distribution system, which is
219 implemented by public license practices. Many people have made
220 generous contributions to the wide range of software distributed
221 through that system in reliance on consistent application of that
222 system; it is up to the author/donor to decide if he or she is willing
223 to distribute software through any other system and a licensee cannot
224 impose that choice.
225
226 This section is intended to make thoroughly clear what is believed to
227 be a consequence of the rest of this License.
228
229 8. If the distribution and/or use of the Program is restricted in
230 certain countries either by patents or by copyrighted interfaces, the
231 original copyright holder who places the Program under this License
232 may add an explicit geographical distribution limitation excluding
233 those countries, so that distribution is permitted only in or among
234 countries not thus excluded. In such case, this License incorporates
235 the limitation as if written in the body of this License.
236
237 9. The Free Software Foundation may publish revised and/or new versions
238 of the General Public License from time to time. Such new versions will
239 be similar in spirit to the present version, but may differ in detail to
240 address new problems or concerns.
241
242 Each version is given a distinguishing version number. If the Program
243 specifies a version number of this License which applies to it and "any
244 later version", you have the option of following the terms and conditions
245 either of that version or of any later version published by the Free
246 Software Foundation. If the Program does not specify a version number of
247 this License, you may choose any version ever published by the Free Software
248 Foundation.
249
250 10. If you wish to incorporate parts of the Program into other free
251 programs whose distribution conditions are different, write to the author
252 to ask for permission. For software which is copyrighted by the Free
253 Software Foundation, write to the Free Software Foundation; we sometimes
254 make exceptions for this. Our decision will be guided by the two goals
255 of preserving the free status of all derivatives of our free software and
256 of promoting the sharing and reuse of software generally.
257
258 NO WARRANTY
259
260 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
261 FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
262 OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
263 PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
264 OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
265 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
266 TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
267 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
268 REPAIR OR CORRECTION.
269
270 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
271 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
272 REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
273 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
274 OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
275 TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
276 YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
277 PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
278 POSSIBILITY OF SUCH DAMAGES.
