of this license document, but changing it is not allowed. |
| |
|
| [This is the first released version of the Lesser GPL. It also counts |
|
| as the successor of the GNU Library Public License, version 2, hence |
|
| the version number 2.1.] |
|
| |
|
| Preamble |
|
| |
|
| The licenses for most software are designed to take away your |
|
| freedom to share and change it. By contrast, the GNU General Public |
|
| Licenses are intended to guarantee your freedom to share and change |
|
| free software--to make sure the software is free for all its users. |
|
| |
|
| This license, the Lesser General Public License, applies to some |
|
| specially designated software packages--typically libraries--of the |
|
| Free Software Foundation and other authors who decide to use it. You |
|
| can use it too, but we suggest you first think carefully about whether |
|
| this license or the ordinary General Public License is the better |
|
| strategy to use in any particular case, based on the explanations |
|
| below. |
|
| |
|
| When we speak of free software, we are referring to freedom of use, |
|
| not price. Our General Public Licenses are designed to make sure that |
|
| you have the freedom to distribute copies of free software (and charge |
|
| for this service if you wish); that you receive source code or can get |
|
| it if you want it; that you can change the software and use pieces of |
|
| it in new free programs; and that you are informed that you can do |
|
| these things. |
|
| |
|
| To protect your rights, we need to make restrictions that forbid |
|
| distributors to deny you these rights or to ask you to surrender these |
|
| rights. These restrictions translate to certain responsibilities for |
|
| you if you distribute copies of the library or if you modify it. |
|
| |
|
| For example, if you distribute copies of the library, whether gratis |
|
| or for a fee, you must give the recipients all the rights that we gave |
|
| you. You must make sure that they, too, receive or can get the source |
|
| code. If you link other code with the library, you must provide |
|
| complete object files to the recipients, so that they can relink them |
|
| with the library after making changes to the library and recompiling |
|
| it. And you must show them these terms so they know their rights. |
|
| |
|
| We protect your rights with a two-step method: (1) we copyright the |
|
| library, and (2) we offer you this license, which gives you legal |
|
| permission to copy, distribute and/or modify the library. |
|
| |
|
| To protect each distributor, we want to make it very clear that |
|
| there is no warranty for the free library. Also, if the library is |
|
| modified by someone else and passed on, the recipients should know |
|
| that what they have is not the original version, so that the original |
|
| author's reputation will not be affected by problems that might be |
|
| introduced by others. |
|
| |
|
| Finally, software patents pose a constant threat to the existence of |
|
| any free program. We wish to make sure that a company cannot |
|
| effectively restrict the users of a free program by obtaining a |
|
| restrictive license from a patent holder. Therefore, we insist that |
|
| any patent license obtained for a version of the library must be |
|
| consistent with the full freedom of use specified in this license. |
|
| |
|
| Most GNU software, including some libraries, is covered by the |
|
| ordinary GNU General Public License. This license, the GNU Lesser |
|
| General Public License, applies to certain designated libraries, and |
|
| is quite different from the ordinary General Public License. We use |
|
| this license for certain libraries in order to permit linking those |
|
| libraries into non-free programs. |
|
| |
|
| When a program is linked with a library, whether statically or using |
|
| a shared library, the combination of the two is legally speaking a |
|
| combined work, a derivative of the original library. The ordinary |
|
| General Public License therefore permits such linking only if the |
|
| entire combination fits its criteria of freedom. The Lesser General |
|
| Public License permits more lax criteria for linking other code with |
|
| the library. |
|
| |
|
| We call this license the "Lesser" General Public License because it |
|
| does Less to protect the user's freedom than the ordinary General |
|
| Public License. It also provides other free software developers Less |
|
| of an advantage over competing non-free programs. These disadvantages |
|
| are the reason we use the ordinary General Public License for many |
|
| libraries. However, the Lesser license provides advantages in certain |
|
| special circumstances. |
|
| |
|
| For example, on rare occasions, there may be a special need to |
|
| encourage the widest possible use of a certain library, so that it |
|
| becomes a de-facto standard. To achieve this, non-free programs must |
|
| be allowed to use the library. A more frequent case is that a free |
|
| library does the same job as widely used non-free libraries. In this |
|
| case, there is little to gain by limiting the free library to free |
|
| software only, so we use the Lesser General Public License. |
|
| |
|
| In other cases, permission to use a particular library in non-free |
|
| programs enables a greater number of people to use a large body of |
|
| free software. For example, permission to use the GNU C Library in |
|
| non-free programs enables many more people to use the whole GNU |
|
| operating system, as well as its variant, the GNU/Linux operating |
|
| system. |
|
| |
|
| Although the Lesser General Public License is Less protective of the |
|
| users' freedom, it does ensure that the user of a program that is |
|
| linked with the Library has the freedom and the wherewithal to run |
|
| that program using a modified version of the Library. |
|
| |
|
| The precise terms and conditions for copying, distribution and |
|
| modification follow. Pay close attention to the difference between a |
|
| "work based on the library" and a "work that uses the library". The |
|
| former contains code derived from the library, whereas the latter must |
|
| be combined with the library in order to run. |

The "Minimal Corresponding Source" for a Combined Work means the |

| warranty; and distribute a copy of this License along with the |
|
| |
2. Conveying Modified Versions. |
| |
|
| |
If you modify a copy of the Library, and, in your modifications, a |
| |
facility refers to a function or data to be supplied by an Application |
| |
that uses the facility (other than as an argument passed when the |
| |
facility is invoked), then you may convey a copy of the modified |
| |
version: |
| |
|
| |
a) under this License, provided that you make a good faith effort to |
| |
ensure that, in the event an Application does not supply the |
| |
function or data, the facility still operates, and performs |
| |
whatever part of its purpose remains meaningful, or |
| |
|
| |
b) under the GNU GPL, with none of the additional permissions of |
| |
this License applicable to that copy. |
| |
|
| |
3. Object Code Incorporating Material from Library Header Files. |
| |
|
| |
The object code form of an Application may incorporate material from |
| |
a header file that is part of the Library. You may convey such object |
| |
code under terms of your choice, provided that, if the incorporated |
| |
material is not limited to numerical parameters, data structure |
| |
layouts and accessors, or small macros, inline functions and templates |
| |
(ten or fewer lines in length), you do both of the following: |
| |
|
| |
a) Give prominent notice with each copy of the object code that the |
| |
Library is used in it and that the Library and its use are |
| |
covered by this License. |
| |
|
| |
b) Accompany the object code with a copy of the GNU GPL and this license |
| |
document. |
| |
|
| |
4. Combined Works. |
| |
|
| |
You may convey a Combined Work under terms of your choice that, |
| |
taken together, effectively do not restrict modification of the |
| |
portions of the Library contained in the Combined Work and reverse |
| |
engineering for debugging such modifications, if you also do each of |
| |
the following: |
| |
|
| |
a) Give prominent notice with each copy of the Combined Work that |
| |
the Library is used in it and that the Library and its use are |
| |
covered by this License. |
| |
|
| |
b) Accompany the Combined Work with a copy of the GNU GPL and this license |
| |
document. |
| |
|
| |
c) For a Combined Work that displays copyright notices during |
| |
execution, include the copyright notice for the Library among |
| |
these notices, as well as a reference directing the user to the |
| |
copies of the GNU GPL and this license document. |
| |
|
| |
d) Do one of the following: |
| |
|
| |
0) Convey the Minimal Corresponding Source under the terms of this |
| |
License, and the Corresponding Application Code in a form |
| |
suitable for, and under terms that permit, the user to |
| |
recombine or relink the Application with a modified version of |
| |
the Linked Version to produce a modified Combined Work, in the |
| |
manner specified by section 6 of the GNU GPL for conveying |
| |
Corresponding Source. |
| |
|
| |
1) Use a suitable shared library mechanism for linking with the |
| |
Library. A suitable mechanism is one that (a) uses at run time |
| |
a copy of the Library already present on the user's computer |
| |
system, and (b) will operate properly with a modified version |
| |
of the Library that is interface-compatible with the Linked |
| |
Version. |
| |
|
| |
e) Provide Installation Information, but only if you would otherwise |
| |
be required to provide such information under section 6 of the |
| |
GNU GPL, and only to the extent that such information is |
| |
necessary to install and execute a modified version of the |
| |
Combined Work produced by recombining or relinking the |
| |
Application with a modified version of the Linked Version. (If |
| |
you use option 4d0, the Installation Information must accompany |
| |
the Minimal Corresponding Source and Corresponding Application |
| |
Code. If you use option 4d1, you must provide the Installation |
| |
Information in the manner specified by section 6 of the GNU GPL |
| |
for conveying Corresponding Source.) |
| |
|
| |
5. Combined Libraries. |
| |
|
| |
You may place library facilities that are a work based on the |
| |
Library side by side in a single library together with other library |
| |
facilities that are not Applications and are not covered by this |
| |
License, and convey such a combined library under terms of your |
| |
choice, if you do both of the following: |
| |
|
| |
a) Accompany the combined library with a copy of the same work based |
| |
on the Library, uncombined with any other library facilities, |
| |
conveyed under the terms of this License. |
| |
|
| |
b) Give prominent notice with the combined library that part of it |
| |
is a work based on the Library, and explaining where to find the |
| |
accompanying uncombined form of the same work. |
| |
|
| |
6. Revised Versions of the GNU Lesser General Public License. |
| |
|
| |
The Free Software Foundation may publish revised and/or new versions |
| |
of the GNU Lesser General Public License from time to time. Such new |
| |
versions will be similar in spirit to the present version, but may |
| |
differ in detail to address new problems or concerns. |
| |
|
| |
Each version is given a distinguishing version number. If the |
| |
Library as you received it specifies that a certain numbered version |
| |
of the GNU Lesser General Public License "or any later version" |
| |
applies to it, you have the option of following the terms and |
| |
conditions either of that published version or of any later version |
| |
published by the Free Software Foundation. If the Library as you |
| |
received it does not specify a version number of the GNU Lesser |
| |
General Public License, you may choose any version of the GNU Lesser |
| |
General Public License ever published by the Free Software Foundation. |
| |
|
| |
If the Library as you received it specifies that a proxy can decide |
| |
whether future versions of the GNU Lesser General Public License shall |
| |
apply, that proxy's public statement of acceptance of any version is |
| |
permanent authorization for you to choose that version for the |
| Library. |
Library. |
| |
|
| You may charge a fee for the physical act of transferring a copy, |
|
| and you may at your option offer warranty protection in exchange for a |
|
| fee. |
|
| |
|
| 2. You may modify your copy or copies of the Library or any portion |
|
| of it, thus forming a work based on the Library, and copy and |
|
| distribute such modifications or work under the terms of Section 1 |
|
| above, provided that you also meet all of these conditions: |
|
| |
|
| a) The modified work must itself be a software library. |
|
| |
|
| b) You must cause the files modified to carry prominent notices |
|
| stating that you changed the files and the date of any change. |
|
| |
|
| c) You must cause the whole of the work to be licensed at no |
|
| charge to all third parties under the terms of this License. |
|
| |
|
| d) If a facility in the modified Library refers to a function or a |
|
| table of data to be supplied by an application program that uses |
|
| the facility, other than as an argument passed when the facility |
|
| is invoked, then you must make a good faith effort to ensure that, |
|
| in the event an application does not supply such function or |
|
| table, the facility still operates, and performs whatever part of |
|
| its purpose remains meaningful. |
|
| |
|
| (For example, a function in a library to compute square roots has |
|
| a purpose that is entirely well-defined independent of the |
|
| application. Therefore, Subsection 2d requires that any |
|
| application-supplied function or table used by this function must |
|
| be optional: if the application does not supply it, the square |
|
| root function must still compute square roots.) |
|
| |
|
| These requirements apply to the modified work as a whole. If |
|
| identifiable sections of that work are not derived from the Library, |
|
| and can be reasonably considered independent and separate works in |
|
| themselves, then this License, and its terms, do not apply to those |
|
| sections when you distribute them as separate works. But when you |
|
| distribute the same sections as part of a whole which is a work based |
|
| on the Library, the distribution of the whole must be on the terms of |
|
| this License, whose permissions for other licensees extend to the |
|
| entire whole, and thus to each and every part regardless of who wrote |
|
| it. |
|
| |
|
| Thus, it is not the intent of this section to claim rights or contest |
|
| your rights to work written entirely by you; rather, the intent is to |
|
| exercise the right to control the distribution of derivative or |
|
| collective works based on the Library. |
|
| |
|
| In addition, mere aggregation of another work not based on the Library |
|
| with the Library (or with a work based on the Library) on a volume of |
|
| a storage or distribution medium does not bring the other work under |
|
| the scope of this License. |
|
| |
|
| 3. You may opt to apply the terms of the ordinary GNU General Public |
|
| License instead of this License to a given copy of the Library. To do |
|
| this, you must alter all the notices that refer to this License, so |
|
| that they refer to the ordinary GNU General Public License, version 2, |
|
| instead of to this License. (If a newer version than version 2 of the |
|
| ordinary GNU General Public License has appeared, then you can specify |
|
| that version instead if you wish.) Do not make any other change in |
|
| these notices. |
|
| |
|
| Once this change is made in a given copy, it is irreversible for |
|
| that copy, so the ordinary GNU General Public License applies to all |
|
| subsequent copies and derivative works made from that copy. |
|
| |
|
| This option is useful when you wish to copy part of the code of |
|
| the Library into a program that is not a library. |
|
| |
|
| 4. You may copy and distribute the Library (or a portion or |
|
| derivative of it, under Section 2) in object code or executable form |
|
| under the terms of Sections 1 and 2 above provided that you accompany |
|
| it with the complete corresponding machine-readable source code, which |
|
| must be distributed under the terms of Sections 1 and 2 above on a |
|
| medium customarily used for software interchange. |
|
| |
|
| If distribution of object code is made by offering access to copy |
|
| from a designated place, then offering equivalent access to copy the |
|
| source code from the same place satisfies the requirement to |
|
| distribute the source code, even though third parties are not |
|
| compelled to copy the source along with the object code. |
|
| |
|
| 5. A program that contains no derivative of any portion of the |
|
| Library, but is designed to work with the Library by being compiled or |
|
| linked with it, is called a "work that uses the Library". Such a |
|
| work, in isolation, is not a derivative work of the Library, and |
|
| therefore falls outside the scope of this License. |
|
| |
|
| However, linking a "work that uses the Library" with the Library |
|
| creates an executable that is a derivative of the Library (because it |
|
| contains portions of the Library), rather than a "work that uses the |
|
| library". The executable is therefore covered by this License. |
|
| Section 6 states terms for distribution of such executables. |
|
| |
|
| When a "work that uses the Library" uses material from a header file |
|
| that is part of the Library, the object code for the work may be a |
|
| derivative work of the Library even though the source code is not. |
|
| Whether this is true is especially significant if the work can be |
|
| linked without the Library, or if the work is itself a library. The |
|
| threshold for this to be true is not precisely defined by law. |
|
| |
|
| If such an object file uses only numerical parameters, data |
|
| structure layouts and accessors, and small macros and small inline |
|
| functions (ten lines or less in length), then the use of the object |
|
| file is unrestricted, regardless of whether it is legally a derivative |
|
| work. (Executables containing this object code plus portions of the |
|
| Library will still fall under Section 6.) |
|
| |
|
| Otherwise, if the work is a derivative of the Library, you may |
|
| distribute the object code for the work under the terms of Section 6. |
|
| Any executables containing that work also fall under Section 6, |
|
| whether or not they are linked directly with the Library itself. |
|
| |
|
| 6. As an exception to the Sections above, you may also combine or |
|
| link a "work that uses the Library" with the Library to produce a |
|
| work containing portions of the Library, and distribute that work |
|
| under terms of your choice, provided that the terms permit |
|
| modification of the work for the customer's own use and reverse |
|
| engineering for debugging such modifications. |
|
| |
|
| You must give prominent notice with each copy of the work that the |
|
| Library is used in it and that the Library and its use are covered by |
|
| this License. You must supply a copy of this License. If the work |
|
| during execution displays copyright notices, you must include the |
|
| copyright notice for the Library among them, as well as a reference |
|
| directing the user to the copy of this License. Also, you must do one |
|
| of these things: |
|
| |
|
| a) Accompany the work with the complete corresponding |
|
| machine-readable source code for the Library including whatever |
|
| changes were used in the work (which must be distributed under |
|
| Sections 1 and 2 above); and, if the work is an executable linked |
|
| with the Library, with the complete machine-readable "work that |
|
| uses the Library", as object code and/or source code, so that the |
|
| user can modify the Library and then relink to produce a modified |
|
| executable containing the modified Library. (It is understood |
|
| that the user who changes the contents of definitions files in the |
|
| Library will not necessarily be able to recompile the application |
|
| to use the modified definitions.) |
|
| |
|
| b) Use a suitable shared library mechanism for linking with the |
|
| Library. A suitable mechanism is one that (1) uses at run time a |
|
| copy of the library already present on the user's computer system, |
|
| rather than copying library functions into the executable, and (2) |
|
| will operate properly with a modified version of the library, if |
|
| the user installs one, as long as the modified version is |
|
| interface-compatible with the version that the work was made with. |
|
| |
|
| c) Accompany the work with a written offer, valid for at least |
|
| three years, to give the same user the materials specified in |
|
| Subsection 6a, above, for a charge no more than the cost of |
|
| performing this distribution. |
|
| |
|
| d) If distribution of the work is made by offering access to copy |
|
| from a designated place, offer equivalent access to copy the above |
|
| specified materials from the same place. |
|
| |
|
| e) Verify that the user has already received a copy of these |
|
| materials or that you have already sent this user a copy. |
|
| |
|
| For an executable, the required form of the "work that uses the |
|
| Library" must include any data and utility programs needed for |
|
| reproducing the executable from it. However, as a special exception, |
|
| the materials to be distributed need not include anything that is |
|
| normally distributed (in either source or binary form) with the major |
|
| components (compiler, kernel, and so on) of the operating system on |
|
| which the executable runs, unless that component itself accompanies |
|
| the executable. |
|
| |
|
| It may happen that this requirement contradicts the license |
|
| restrictions of other proprietary libraries that do not normally |
|
| accompany the operating system. Such a contradiction means you cannot |
|
| use both them and the Library together in an executable that you |
|
| distribute. |
|
| |
|
| 7. You may place library facilities that are a work based on the |
|
| Library side-by-side in a single library together with other library |
|
| facilities not covered by this License, and distribute such a combined |
|
| library, provided that the separate distribution of the work based on |
|
| the Library and of the other library facilities is otherwise |
|
| permitted, and provided that you do these two things: |
|
| |
|
| a) Accompany the combined library with a copy of the same work |
|
| based on the Library, uncombined with any other library |
|
| facilities. This must be distributed under the terms of the |
|
| Sections above. |
|
| |
|
| b) Give prominent notice with the combined library of the fact |
|
| that part of it is a work based on the Library, and explaining |
|
| where to find the accompanying uncombined form of the same work. |
|
| |
|
| 8. You may not copy, modify, sublicense, link with, or distribute |
|
| the Library except as expressly provided under this License. Any |
|
| attempt otherwise to copy, modify, sublicense, link with, or |
|
| distribute the Library is void, and will automatically terminate your |
|
| rights under this License. However, parties who have received copies, |
|
| or rights, from you under this License will not have their licenses |
|
| terminated so long as such parties remain in full compliance. |
|
| |
|
| 9. You are not required to accept this License, since you have not |
|
| signed it. However, nothing else grants you permission to modify or |
|
| distribute the Library or its derivative works. These actions are |
|
| prohibited by law if you do not accept this License. Therefore, by |
|
| modifying or distributing the Library (or any work based on the |
|
| Library), you indicate your acceptance of this License to do so, and |
|
| all its terms and conditions for copying, distributing or modifying |
|
| the Library or works based on it. |
|
| |
|
| 10. Each time you redistribute the Library (or any work based on the |
|
| Library), the recipient automatically receives a license from the |
|
| original licensor to copy, distribute, link with or modify the Library |
|
| subject to these terms and conditions. You may not impose any further |
|
| restrictions on the recipients' exercise of the rights granted herein. |
|
| You are not responsible for enforcing compliance by third parties with |
|
| this License. |
|
| |
|
| 11. If, as a consequence of a court judgment or allegation of patent |
|
| infringement or for any other reason (not limited to patent issues), |
|
| conditions are imposed on you (whether by court order, agreement or |
|
| otherwise) that contradict the conditions of this License, they do not |
|
| excuse you from the conditions of this License. If you cannot |
|
| distribute so as to satisfy simultaneously your obligations under this |
|
| License and any other pertinent obligations, then as a consequence you |
|
| may not distribute the Library at all. For example, if a patent |
|
| license would not permit royalty-free redistribution of the Library by |
|
| all those who receive copies directly or indirectly through you, then |
|
| the only way you could satisfy both it and this License would be to |
|
| refrain entirely from distribution of the Library. |
|
| |
|
| If any portion of this section is held invalid or unenforceable under |
|
| any particular circumstance, the balance of the section is intended to |
|
| apply, and the section as a whole is intended to apply in other |
|
| circumstances. |
|
| |
|
| It is not the purpose of this section to induce you to infringe any |
|
| patents or other property right claims or to contest validity of any |
|
| such claims; this section has the sole purpose of protecting the |
|
| integrity of the free software distribution system which is |
|
| implemented by public license practices. Many people have made |
|
| generous contributions to the wide range of software distributed |
|
| through that system in reliance on consistent application of that |
|
| system; it is up to the author/donor to decide if he or she is willing |
|
| to distribute software through any other system and a licensee cannot |
|
| impose that choice. |
|
| |
|
| This section is intended to make thoroughly clear what is believed to |
|
| be a consequence of the rest of this License. |
|
| |
|
| 12. If the distribution and/or use of the Library is restricted in |
|
| certain countries either by patents or by copyrighted interfaces, the |
|
| original copyright holder who places the Library under this License |
|
| may add an explicit geographical distribution limitation excluding those |
|
| countries, so that distribution is permitted only in or among |
|
| countries not thus excluded. In such case, this License incorporates |
|
| the limitation as if written in the body of this License. |
|
| |
|
| 13. The Free Software Foundation may publish revised and/or new |
|
| versions of the Lesser General Public License from time to time. |
|
| Such new versions will be similar in spirit to the present version, |
|
| but may differ in detail to address new problems or concerns. |
|
| |
|
| Each version is given a distinguishing version number. If the Library |
|
| specifies a version number of this License which applies to it and |
|
| "any later version", you have the option of following the terms and |
|
| conditions either of that version or of any later version published by |
|
| the Free Software Foundation. If the Library does not specify a |
|
| license version number, you may choose any version ever published by |
|
| the Free Software Foundation. |
|
| |
|
| 14. If you wish to incorporate parts of the Library into other free |
|
| programs whose distribution conditions are incompatible with these, |
|
| write to the author to ask for permission. For software which is |
|
| copyrighted by the Free Software Foundation, write to the Free |
|
| Software Foundation; we sometimes make exceptions for this. Our |
|
| decision will be guided by the two goals of preserving the free status |
|
| of all derivatives of our free software and of promoting the sharing |
|
| and reuse of software generally. |
|
| |
|
| NO WARRANTY |
|
| |
|
| 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO |
|
| WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. |
|
| EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR |
|
| OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY |
|
| KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE |
|
| IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR |
|
| PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE |
|
| LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME |
|
| THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. |
|
| |
|
| 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN |
|
| WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY |
|
| AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU |
|
| FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR |
|
| CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE |
|
| LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING |
|
| RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A |
|
| FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF |
|
| SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH |
|
| DAMAGES. |
|
| |
|
| END OF TERMS AND CONDITIONS |
|
| |
|
| How to Apply These Terms to Your New Libraries |
|
| |
|
| If you develop a new library, and you want it to be of the greatest |
|
| possible use to the public, we recommend making it free software that |
|
| everyone can redistribute and change. You can do so by permitting |
|
| redistribution under these terms (or, alternatively, under the terms |
|
| of the ordinary General Public License). |
|
| |
|
| To apply these terms, attach the following notices to the library. |
|
| It is safest to attach them to the start of each source file to most |
|
| effectively convey the exclusion of warranty; and each file should |
|
| have at least the "copyright" line and a pointer to where the full |
|
| notice is found. |
|
| |
|
| |
|
| <one line to give the library's name and a brief idea of what it does.> |
|

|
| Also add information on how to contact you by electronic and paper mail. |
|
| |
|
| You should also get your employer (if you work as a programmer) or |
|
| your school, if any, to sign a "copyright disclaimer" for the library, |
|
