+The GNU Lesser General Public License (LGPL)

+

+Copyright (C) 1991, 1999 Free Software Foundation, Inc. 59 Temple

+Place, Suite 330, Boston, MA 02111-1307 USA 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.

+

+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
