-		  GNU LESSER GENERAL PUBLIC LICENSE

-		       Version 2.1, February 1999

-

- 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.

-

-		  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

-    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!
