| {\bf\large Preamble} | ||||
| \end{center} | ||||
| 
 | ||||
| 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. | ||||

| \begin{enumerate} | ||||
| 
 | ||||
| \addtocounter{enumi}{-1} | ||||
| 
 | ||||
| \item | ||||
| 
 | ||||
| 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. | ||||
|    | ||||
| \item  | ||||
| 
 | ||||
| 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. | ||||
| 
 | ||||
| \item | ||||
| 
 | ||||
| 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: | ||||
| 
 | ||||
| \begin{enumerate} | ||||
| 
 | ||||
|   \item | ||||
| 
 | ||||
|     The modified work must itself be a software library. | ||||
| 
 | ||||
|   \item | ||||
| 
 | ||||
|     You must cause the files modified to carry prominent notices stating | ||||
|     that you changed the files and the date of any change. | ||||
| 
 | ||||
|   \item | ||||
| 
 | ||||
|     You must cause the whole of the work to be licensed at no charge to | ||||
|     all third parties under the terms of this License. | ||||
| 
 | ||||
|   \item  | ||||
|     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.) | ||||
| \end{enumerate} | ||||
| 
 | ||||
| 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 | ||||
|     License as published by the Free Software Foundation; either | ||||
|     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 | ||||
|     License along with this library; if not, write to the Free Software | ||||
|     Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA  02111-1307  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: | ||||
| 
 | ||||
|   Yoyodyne, Inc., hereby disclaims all copyright interest in the | ||||
|   library `Frob' (a library for tweaking knobs) written by James Random Hacker. | ||||
| 
 | ||||
|   <signature of Ty Coon>, 1 April 1990 | ||||
|   Ty Coon, President of Vice | ||||
| 
 | ||||
| That's all there is to it! | ||||
