|
* Everyone is permitted to copy and distribute verbatim copies
|
|
* 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.
|
|
*
|
|
* GNU LESSER GENERAL PUBLIC LICENSE
|
|
* TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
|
|
*
|
|
* 0. This License Agreement applies to any software library or other
|
|
* program which contains a notice placed by the copyright holder or
|
|
* other authorized party saying it may be distributed under the terms of
|
|
* this Lesser General Public License (also called "this License").
|
|
* Each licensee is addressed as "you".
|
|
*
|
|
* A "library" means a collection of software functions and/or data
|
|
* prepared so as to be conveniently linked with application programs
|
|
* (which use some of those functions and data) to form executables.
|
|
*
|
|
* The "Library", below, refers to any such software library or work
|
|
* which has been distributed under these terms. A "work based on the
|
|
* Library" means either the Library or any derivative work under
|
|
* copyright law: that is to say, a work containing the Library or a
|
|
* portion of it, either verbatim or with modifications and/or translated
|
|
* straightforwardly into another language. (Hereinafter, translation is
|
|
* included without limitation in the term "modification".)
|
|
*
|
|
* "Source code" for a work means the preferred form of the work for
|
|
* making modifications to it. For a library, complete source code means
|
|
* all the source code for all modules it contains, plus any associated
|
|
* interface definition files, plus the scripts used to control compilation
|
|
* and installation of the library.
|
|
*
|
|
* Activities other than copying, distribution and modification are not
|
|
* covered by this License; they are outside its scope. The act of
|
|
* running a program using the Library is not restricted, and output from
|
|
* such a program is covered only if its contents constitute a work based
|
|
* on the Library (independent of the use of the Library in a tool for
|
|
* writing it). Whether that is true depends on what the Library does
|
|
* and what the program that uses the Library does.
|
|
*
|
|
* 1. You may copy and distribute verbatim copies of the Library's
|
|
* complete source code as you receive it, in any medium, provided that
|
|
* you conspicuously and appropriately publish on each copy an
|
|
* appropriate copyright notice and disclaimer of warranty; keep intact
|
|
* all the notices that refer to this License and to the absence of any
|
|
* warranty; and distribute a copy of this License along with the
|
|
* 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.>
|
|
* Copyright (C) <year> <name of author>

*
|

* This library is free software; you can redistribute it and/or
|
|
* modify it under the terms of the GNU Lesser General Public

|
|
* version 2.1 of the License, or (at your option) any later version.
|
|
*
|
|
* This library is distributed in the hope that it will be useful,
|
|
* but WITHOUT ANY WARRANTY; without even the implied warranty of
|
|
* MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU
|
|
* Lesser General Public License for more details.
|
|
*
|
|
* You should have received a copy of the GNU Lesser General Public
|
|

|
|
* Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
|
|
*
|
|
* 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, if
|
|
* necessary. Here is a sample; alter the names:
|
