   2. Source Code License.

   2.1. The Initial Developer Grant.
   The Initial Developer hereby grants You a world-wide, royalty-free, non-exclusive license, subject to third party intellectual property claims:

   (a) to use, reproduce, modify, display, perform, sublicense and distribute the Original Code (or portions thereof) with or without Modifications, or as part of a Larger Work; and

   (b) under patents now or hereafter owned or controlled by Initial Developer, to make, have made, use and sell ("Utilize") the Original Code (or portions thereof), but solely to the extent that
   any such patent is reasonably necessary to enable You to Utilize the Original Code (or portions thereof) and not to any greater extent that may be necessary to Utilize further Modifications or
   combinations.

   2.2. Contributor Grant.
   Each Contributor hereby grants You a world-wide, royalty-free, non-exclusive license, subject to third party intellectual property claims:

   (a) to use, reproduce, modify, display, perform, sublicense and distribute the Modifications created by such Contributor (or portions thereof) either on an unmodified basis, with other Modifications, as Covered Code or as part of a Larger Work; and

   (b) under patents now or hereafter owned or controlled by Contributor, to Utilize the Contributor Version (or portions thereof), but solely to the extent that any such patent is reasonably necessary to enable You to Utilize the Contributor Version (or portions thereof), and not to any greater extent that
   may be necessary to Utilize further Modifications or combinations.

   3. Distribution Obligations.

   3.1. Application of License.
   The Modifications which You create or to which You contribute are governed by the terms of this License, including without limitation Section 2.2. The Source Code version of Covered Code may be distributed only under the terms of this License or a future version of this License released under Section 6.1, and You must include a copy of this License with every copy of the Source Code You distribute. You may not offer or impose any terms on any Source Code version that alters or
   restricts the applicable version of this License or the recipients' rights hereunder. However, You may include an additional document offering the additional rights described in Section 3.5.

   3.2. Availability of Source Code.
   Any Modification which You create or to which You contribute must be made available in Source Code form under the terms of this License either on the same media as an Executable version or via an accepted Electronic Distribution Mechanism to anyone to whom you made an Executable version available; and if made available via Electronic Distribution Mechanism, must remain available for at least twelve (12) months after the date it initially became available, or at least six (6) months after a subsequent version of that particular Modification has been made available to such recipients. You are responsible for ensuring that the Source Code version remains available even if the Electronic Distribution Mechanism is maintained by a third party.

   3.3. Description of Modifications.
   You must cause all Covered Code to which you contribute to contain a file documenting the changes You made to create that Covered Code and the date of any change. You must include a prominent statement that the Modification is derived, directly or indirectly, from Original Code provided by the Initial Developer and including the name of the Initial Developer in (a) the Source Code, and (b) in any notice in an Executable version or related documentation in which You describe the origin or ownership of the Covered Code.

   3.4. Intellectual Property Matters

   (a) Third Party Claims.
   If You have knowledge that a party claims an intellectual property right in particular functionality or code (or its utilization under this License), you must include a text file with the source code distribution titled "LEGAL" which describes the claim and the party making the claim in sufficient detail that a recipient will know whom to contact. If you obtain such knowledge after You make Your Modification available as described in Section 3.2, You shall promptly modify the LEGAL file in all copies You make
   available thereafter and shall take other steps (such as notifying appropriate mailing lists or newsgroups) reasonably calculated to inform those who received the Covered Code that new knowledge has been obtained.

   (b) Contributor APIs.
   If Your Modification is an application programming interface and You own or control patents which are reasonably necessary to implement that API, you must also include this information in the LEGAL file.

   3.5. Required Notices.
   You must duplicate the notice in Exhibit A in each file of the Source Code, and this License in any documentation for the Source Code, where You describe recipients' rights relating to Covered Code. If You created one or more Modification(s), You may add your name as a Contributor to the notice described in Exhibit A. If it is not possible to put such notice in a particular Source Code file due to its
   structure, then you must include such notice in a location (such as a relevant directory file) where a user would be likely to look for such a notice. You may choose to offer, and to charge a fee for, warranty, support, indemnity or liability obligations to one or more recipients of Covered Code. However, You may do so only on Your own behalf, and not on behalf of the Initial Developer or any Contributor. You must make it absolutely clear than any such warranty, support, indemnity or
   liability obligation is offered by You alone, and You hereby agree to indemnify the Initial Developer and every Contributor for any liability incurred by the Initial Developer or such Contributor as a result of
   warranty, support, indemnity or liability terms You offer.

   3.6. Distribution of Executable Versions.
   You may distribute Covered Code in Executable form only if the requirements of Section 3.1-3.5 have been met for that Covered Code, and if You include a notice stating that the Source Code version of the Covered Code is available under the terms of this License, including a description of how and where You have fulfilled the obligations of Section 3.2. The notice must be conspicuously included in any notice in an Executable version, related documentation or collateral in which You
   describe recipients' rights relating to the Covered Code. You may distribute the Executable version of Covered Code under a license of Your choice, which may contain terms different from this License,
   provided that You are in compliance with the terms of this License and that the license for the Executable version does not attempt to limit or alter the recipient's rights in the Source Code version from the rights set forth in this License. If You distribute the Executable version under a different license You must make it absolutely clear that any terms which differ from this License are offered by You alone, not by the Initial Developer or any Contributor. You hereby agree to indemnify the Initial Developer and every Contributor for any liability incurred by the Initial Developer or such Contributor as a result of any such terms You offer.

   3.7. Larger Works.
   You may create a Larger Work by combining Covered Code with other code not governed by the terms of this License and distribute the Larger Work as a single product. In such a case, You must make sure the requirements of this License are fulfilled for the Covered Code.

   4. Inability to Comply Due to Statute or Regulation.

   If it is impossible for You to comply with any of the terms of this License with respect to some or all of the Covered Code due to statute or regulation then You must: (a) comply with the terms of this License to the maximum extent possible; and (b) describe the limitations and the code they affect. Such description must be included in the LEGAL file described in Section 3.4 and must be included with all distributions of the Source Code. Except to the extent prohibited by statute or regulation, such description must be sufficiently detailed for a recipient of ordinary skill to be able to understand it.

   5. Application of this License.

   This License applies to code to which the Initial Developer has attached the notice in Exhibit A, and to related Covered Code.

   6. Versions of the License.

   6.1. New Versions.
   Floris van den Berg may publish revised and/or new versions of the License from time to time. Each version will be given a distinguishing version number.

   6.2. Effect of New Versions.
   Once Covered Code has been published under a particular version of the License, You may always continue to use it under the terms of that version. You may also choose to use such Covered Code under the terms of any subsequent version of the License published by Floris van den Berg
   No one other than Floris van den Berg has the right to modify the terms applicable to Covered Code created under this License.

   6.3. Derivative Works.
   If you create or use a modified version of this License (which you may only do in order to apply it to code which is not already Covered Code governed by this License), you must (a) rename Your license so that the phrases "FreeImage", `FreeImage Public License", "FIPL", or any confusingly similar phrase do not appear anywhere in your license and (b) otherwise make it clear that your version of the license contains terms which differ from the FreeImage Public License. (Filling in the name of the Initial Developer, Original Code or Contributor in the notice described in Exhibit A shall not of themselves be deemed to be modifications of this License.)

   7. DISCLAIMER OF WARRANTY.

   COVERED CODE IS PROVIDED UNDER THIS LICENSE ON AN "AS IS" BASIS, WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, WITHOUT LIMITATION, WARRANTIES THAT THE COVERED CODE IS FREE OF DEFECTS, MERCHANTABLE, FIT FOR A PARTICULAR PURPOSE OR NON-INFRINGING. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE COVERED CODE IS WITH YOU. SHOULD ANY COVERED CODE PROVE DEFECTIVE IN ANY RESPECT, YOU (NOT THE INITIAL DEVELOPER OR ANY OTHER CONTRIBUTOR) ASSUME THE COST OF ANY NECESSARY SERVICING, REPAIR OR CORRECTION. THIS DISCLAIMER OF WARRANTY CONSTITUTES AN ESSENTIAL PART OF THIS LICENSE. NO USE OF ANY COVERED CODE IS AUTHORIZED HEREUNDER EXCEPT UNDER THIS DISCLAIMER.

   8. TERMINATION.

   This License and the rights granted hereunder will terminate automatically if You fail to comply with terms herein and fail to cure such breach within 30 days of becoming aware of the breach. All sublicenses to the Covered Code which are properly granted shall survive any termination of this License. Provisions which, by their nature, must remain in effect beyond the termination of this License shall survive.

   9. LIMITATION OF LIABILITY.

   UNDER NO CIRCUMSTANCES AND UNDER NO LEGAL THEORY, WHETHER TORT (INCLUDING NEGLIGENCE), CONTRACT, OR OTHERWISE, SHALL THE INITIAL DEVELOPER, ANY OTHER CONTRIBUTOR, OR ANY DISTRIBUTOR OF COVERED CODE, OR ANY SUPPLIER OF ANY OF SUCH PARTIES, BE LIABLE TO YOU OR ANY OTHER PERSON FOR ANY INDIRECT, SPECIAL, INCIDENTAL, OR CONSEQUENTIAL DAMAGES OF ANY CHARACTER INCLUDING, WITHOUT LIMITATION, DAMAGES FOR LOSS OF GOODWILL, WORK STOPPAGE, COMPUTER FAILURE OR MALFUNCTION, OR ANY AND ALL OTHER COMMERCIAL DAMAGES OR LOSSES, EVEN IF SUCH PARTY SHALL HAVE BEEN INFORMED OF THE POSSIBILITY OF SUCH DAMAGES. THIS LIMITATION OF LIABILITY SHALL NOT APPLY TO LIABILITY FOR DEATH OR PERSONAL INJURY RESULTING FROM SUCH PARTY'S NEGLIGENCE TO THE EXTENT APPLICABLE LAW PROHIBITS SUCH LIMITATION. SOME JURISDICTIONS DO NOT ALLOW THE
   EXCLUSION OR LIMITATION OF INCIDENTAL OR CONSEQUENTIAL DAMAGES, SO THAT EXCLUSION AND LIMITATION MAY NOT APPLY TO YOU.

   10. U.S. GOVERNMENT END USERS.

   The Covered Code is a "commercial item," as that term is defined in 48 C.F.R. 2.101 (Oct. 1995), consisting of "commercial computer software" and "commercial computer software documentation," as such terms are used in 48 C.F.R. 12.212 (Sept. 1995). Consistent with 48 C.F.R. 12.212 and 48 C.F.R. 227.7202-1 through 227.7202-4 (June 1995), all U.S. Government End Users acquire Covered Code with only those rights set forth herein.

   11. MISCELLANEOUS.

   This License represents the complete agreement concerning subject matter hereof. If any provision of this License is held to be unenforceable, such provision shall be reformed only to the extent necessary to make it enforceable. This License shall be governed by Dutch law provisions (except to the extent applicable law, if any, provides otherwise), excluding its conflict-of-law provisions. With respect to disputes in which at least one party is a citizen of, or an entity chartered or registered to do business in, the The Netherlands: (a) unless otherwise agreed in writing, all disputes relating to this License (excepting any dispute relating to intellectual property rights) shall be subject to final and binding arbitration, with the losing party paying all costs of arbitration; (b) any arbitration relating to this Agreement shall be held in Almelo, The Netherlands; and (c) any litigation relating to this Agreement shall be subject to the jurisdiction of the court of Almelo, The Netherlands with the losing party responsible for costs, including without limitation, court costs and reasonable attorneys fees and expenses. Any law or regulation which provides that the language of a contract shall be construed against the drafter shall not apply to this License.

   12. RESPONSIBILITY FOR CLAIMS.

   Except in cases where another Contributor has failed to comply with Section 3.4, You are responsible for damages arising, directly or indirectly, out of Your utilization of rights under this License, based
   on the number of copies of Covered Code you made available, the revenues you received from utilizing such rights, and other relevant factors. You agree to work with affected parties to distribute
   responsibility on an equitable basis.

                       The FreeType Project LICENSE
                       ----------------------------

                               2006-Jan-27

                       Copyright 1996-2002, 2006 by
             David Turner, Robert Wilhelm, and Werner Lemberg



   Introduction
   ============

     The FreeType  Project is distributed in  several archive packages;
     some of them may contain, in addition to the FreeType font engine,
     various tools and  contributions which rely on, or  relate to, the
     FreeType Project.

     This  license applies  to all  files found  in such  packages, and
     which do not  fall under their own explicit  license.  The license
     affects  thus  the  FreeType   font  engine,  the  test  programs,
     documentation and makefiles, at the very least.

     This  license   was  inspired  by  the  BSD,   Artistic,  and  IJG
     (Independent JPEG  Group) licenses, which  all encourage inclusion
     and  use of  free  software in  commercial  and freeware  products
     alike.  As a consequence, its main points are that:

       o We don't promise that this software works. However, we will be
         interested in any kind of bug reports. (`as is' distribution)

       o You can  use this software for whatever you  want, in parts or
         full form, without having to pay us. (`royalty-free' usage)

       o You may not pretend that  you wrote this software.  If you use
         it, or  only parts of it,  in a program,  you must acknowledge
         somewhere  in  your  documentation  that  you  have  used  the
         FreeType code. (`credits')

     We  specifically  permit  and  encourage  the  inclusion  of  this
     software, with  or without modifications,  in commercial products.
     We  disclaim  all warranties  covering  The  FreeType Project  and
     assume no liability related to The FreeType Project.


     Finally,  many  people  asked  us  for  a  preferred  form  for  a
     credit/disclaimer to use in compliance with this license.  We thus
     encourage you to use the following text:

      """
       Portions of this software are copyright © <year> The FreeType
       Project (www.freetype.org).  All rights reserved.
      """

     Please replace <year> with the value from the FreeType version you
     actually use.


   Legal Terms
   ===========

   0. Definitions
   --------------

     Throughout this license,  the terms `package', `FreeType Project',
     and  `FreeType  archive' refer  to  the  set  of files  originally
     distributed  by the  authors  (David Turner,  Robert Wilhelm,  and
     Werner Lemberg) as the `FreeType Project', be they named as alpha,
     beta or final release.

     `You' refers to  the licensee, or person using  the project, where
     `using' is a generic term including compiling the project's source
     code as  well as linking it  to form a  `program' or `executable'.
     This  program is  referred to  as  `a program  using the  FreeType
     engine'.

     This  license applies  to all  files distributed  in  the original
     FreeType  Project,   including  all  source   code,  binaries  and
     documentation,  unless  otherwise  stated   in  the  file  in  its
     original, unmodified form as  distributed in the original archive.
     If you are  unsure whether or not a particular  file is covered by
     this license, you must contact us to verify this.

     The FreeType  Project is copyright (C) 1996-2000  by David Turner,
     Robert Wilhelm, and Werner Lemberg.  All rights reserved except as
     specified below.

   1. No Warranty
   --------------

     THE FREETYPE PROJECT  IS PROVIDED `AS IS' WITHOUT  WARRANTY OF ANY
     KIND, EITHER  EXPRESS OR IMPLIED,  INCLUDING, BUT NOT  LIMITED TO,
     WARRANTIES  OF  MERCHANTABILITY   AND  FITNESS  FOR  A  PARTICULAR
     PURPOSE.  IN NO EVENT WILL ANY OF THE AUTHORS OR COPYRIGHT HOLDERS
     BE LIABLE  FOR ANY DAMAGES CAUSED  BY THE USE OR  THE INABILITY TO
     USE, OF THE FREETYPE PROJECT.

   2. Redistribution
   -----------------

     This  license  grants  a  worldwide, royalty-free,  perpetual  and
     irrevocable right  and license to use,  execute, perform, compile,
     display,  copy,   create  derivative  works   of,  distribute  and
     sublicense the  FreeType Project (in  both source and  object code
     forms)  and  derivative works  thereof  for  any  purpose; and  to
     authorize others  to exercise  some or all  of the  rights granted
     herein, subject to the following conditions:

       o Redistribution of  source code  must retain this  license file
         (`FTL.TXT') unaltered; any  additions, deletions or changes to
         the original  files must be clearly  indicated in accompanying
         documentation.   The  copyright   notices  of  the  unaltered,
         original  files must  be  preserved in  all  copies of  source
         files.

       o Redistribution in binary form must provide a  disclaimer  that
         states  that  the software is based in part of the work of the
         FreeType Team,  in  the  distribution  documentation.  We also
         encourage you to put an URL to the FreeType web page  in  your
         documentation, though this isn't mandatory.

     These conditions  apply to any  software derived from or  based on

     following phrases to refer  to this software in your documentation
     or advertising  materials: `FreeType Project',  `FreeType Engine',
     `FreeType library', or `FreeType Distribution'.

     As  you have  not signed  this license,  you are  not  required to

         "Derivative Works" shall mean any work, whether in Source or Object
         form, that is based on (or derived from) the Work and for which the
         editorial revisions, annotations, elaborations, or other modifications
         represent, as a whole, an original work of authorship. For the purposes
         of this License, Derivative Works shall not include works that remain
         separable from, or merely link (or bind by name) to the interfaces of,
         the Work and Derivative Works thereof.

         "Contribution" shall mean any work of authorship, including
         the original version of the Work and any modifications or additions
         to that Work or Derivative Works thereof, that is intentionally
         submitted to Licensor for inclusion in the Work by the copyright owner
         or by an individual or Legal Entity authorized to submit on behalf of
         the copyright owner. For the purposes of this definition, "submitted"

         subsequently incorporated within the Work.

      2. Grant of Copyright License. Subject to the terms and conditions of
         this License, each Contributor hereby grants to You a perpetual,
         worldwide, non-exclusive, no-charge, royalty-free, irrevocable
         copyright license to reproduce, prepare Derivative Works of,
         publicly display, publicly perform, sublicense, and distribute the
         Work and such Derivative Works in Source or Object form.

      3. Grant of Patent License. Subject to the terms and conditions of
         this License, each Contributor hereby grants to You a perpetual,

         (except as stated in this section) patent license to make, have made,
         use, offer to sell, sell, import, and otherwise transfer the Work,
         where such license applies only to those patent claims licensable
         by such Contributor that are necessarily infringed by their
         Contribution(s) alone or by combination of their Contribution(s)
         with the Work to which such Contribution(s) was submitted. If You
         institute patent litigation against any entity (including a
         cross-claim or counterclaim in a lawsuit) alleging that the Work
         or a Contribution incorporated within the Work constitutes direct
         or contributory patent infringement, then any patent licenses
         granted to You under this License for that Work shall terminate
         as of the date such litigation is filed.

      4. Redistribution. You may reproduce and distribute copies of the
         Work or Derivative Works thereof in any medium, with or without
         modifications, and in Source or Object form, provided that You
         meet the following conditions:

         (a) You must give any other recipients of the Work or
             Derivative Works a copy of this License; and

         (b) You must cause any modified files to carry prominent notices
             stating that You changed the files; and

         (c) You must retain, in the Source form of any Derivative Works
             that You distribute, all copyright, patent, trademark, and
             attribution notices from the Source form of the Work,
             excluding those notices that do not pertain to any part of
             the Derivative Works; and

         (d) If the Work includes a "NOTICE" text file as part of its
             distribution, then any Derivative Works that You distribute must
             include a readable copy of the attribution notices contained
             within such NOTICE file, excluding those notices that do not
             pertain to any part of the Derivative Works, in at least one
             of the following places: within a NOTICE text file distributed
             as part of the Derivative Works; within the Source form or
             documentation, if provided along with the Derivative Works; or,
             within a display generated by the Derivative Works, if and
             wherever such third-party notices normally appear. The contents
             of the NOTICE file are for informational purposes only and
             do not modify the License. You may add Your own attribution
             notices within Derivative Works that You distribute, alongside
             or as an addendum to the NOTICE text from the Work, provided
             that such additional attribution notices cannot be construed
             as modifying the License.

         You may add Your own copyright statement to Your modifications and
         may provide additional or different license terms and conditions
         for use, reproduction, or distribution of Your modifications, or
         for any such Derivative Works as a whole, provided Your use,
         reproduction, and distribution of the Work otherwise complies with
         the conditions stated in this License.

      5. Submission of Contributions. Unless You explicitly state otherwise,
         any Contribution intentionally submitted for inclusion in the Work
         by You to the Licensor shall be under the terms and conditions of
         this License, without any additional terms or conditions.
         Notwithstanding the above, nothing herein shall supersede or modify
         the terms of any separate license agreement you may have executed
         with Licensor regarding such Contributions.

      6. Trademarks. This License does not grant permission to use the trade
         names, trademarks, service marks, or product names of the Licensor,
         except as required for reasonable and customary use in describing the
         origin of the Work and reproducing the content of the NOTICE file.

      7. Disclaimer of Warranty. Unless required by applicable law or
         agreed to in writing, Licensor provides the Work (and each
         Contributor provides its Contributions) on an "AS IS" BASIS,
         WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
         implied, including, without limitation, any warranties or conditions
         of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
         PARTICULAR PURPOSE. You are solely responsible for determining the
         appropriateness of using or redistributing the Work and assume any
         risks associated with Your exercise of permissions under this License.

      8. Limitation of Liability. In no event and under no legal theory,
         whether in tort (including negligence), contract, or otherwise,
         unless required by applicable law (such as deliberate and grossly
         negligent acts) or agreed to in writing, shall any Contributor be
         liable to You for damages, including any direct, indirect, special,
         incidental, or consequential damages of any character arising as a
         result of this License or out of the use or inability to use the
         Work (including but not limited to damages for loss of goodwill,
         work stoppage, computer failure or malfunction, or any and all
         other commercial damages or losses), even if such Contributor
         has been advised of the possibility of such damages.

      9. Accepting Warranty or Additional Liability. While redistributing
         the Work or Derivative Works thereof, You may choose to offer,
         and charge a fee for, acceptance of support, warranty, indemnity,
         or other liability obligations and/or rights consistent with this
         License. However, in accepting such obligations, You may act only
         on Your own behalf and on Your sole responsibility, not on behalf
         of any other Contributor, and only if You agree to indemnify,
         defend, and hold each Contributor harmless for any liability
         incurred by, or claims asserted against, such Contributor by reason
         of your accepting any such warranty or additional liability.

      TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION

      1. Definitions.

         "License" shall mean the terms and conditions for use, reproduction,
         and distribution as defined by Sections 1 through 9 of this document.

         "Licensor" shall mean the copyright owner or entity authorized by
         the copyright owner that is granting the License.

         "Legal Entity" shall mean the union of the acting entity and all
         other entities that control, are controlled by, or are under common
         control with that entity. For the purposes of this definition,
         "control" means (i) the power, direct or indirect, to cause the
         direction or management of such entity, whether by contract or
         otherwise, or (ii) ownership of fifty percent (50%) or more of the
         outstanding shares, or (iii) beneficial ownership of such entity.

         "You" (or "Your") shall mean an individual or Legal Entity
         exercising permissions granted by this License.

         "Source" form shall mean the preferred form for making modifications,
         including but not limited to software source code, documentation
         source, and configuration files.

         "Object" form shall mean any form resulting from mechanical
         transformation or translation of a Source form, including but
         not limited to compiled object code, generated documentation,
         and conversions to other media types.

         "Work" shall mean the work of authorship, whether in Source or
         Object form, made available under the License, as indicated by a
         copyright notice that is included in or attached to the work
         (an example is provided in the Appendix below).

         "Derivative Works" shall mean any work, whether in Source or Object
         form, that is based on (or derived from) the Work and for which the
         editorial revisions, annotations, elaborations, or other modifications
         represent, as a whole, an original work of authorship. For the purposes
         of this License, Derivative Works shall not include works that remain
         separable from, or merely link (or bind by name) to the interfaces of,
         the Work and Derivative Works thereof.

         "Contribution" shall mean any work of authorship, including
         the original version of the Work and any modifications or additions
         to that Work or Derivative Works thereof, that is intentionally
         submitted to Licensor for inclusion in the Work by the copyright owner
         or by an individual or Legal Entity authorized to submit on behalf of
         the copyright owner. For the purposes of this definition, "submitted"
         means any form of electronic, verbal, or written communication sent
         to the Licensor or its representatives, including but not limited to
         communication on electronic mailing lists, source code control systems,
         and issue tracking systems that are managed by, or on behalf of, the
         Licensor for the purpose of discussing and improving the Work, but
         excluding communication that is conspicuously marked or otherwise
         designated in writing by the copyright owner as "Not a Contribution."

         "Contributor" shall mean Licensor and any individual or Legal Entity
         on behalf of whom a Contribution has been received by Licensor and
         subsequently incorporated within the Work.

      2. Grant of Copyright License. Subject to the terms and conditions of
         this License, each Contributor hereby grants to You a perpetual,
         worldwide, non-exclusive, no-charge, royalty-free, irrevocable
         copyright license to reproduce, prepare Derivative Works of,
         publicly display, publicly perform, sublicense, and distribute the
         Work and such Derivative Works in Source or Object form.

      3. Grant of Patent License. Subject to the terms and conditions of
         this License, each Contributor hereby grants to You a perpetual,
         worldwide, non-exclusive, no-charge, royalty-free, irrevocable
         (except as stated in this section) patent license to make, have made,
         use, offer to sell, sell, import, and otherwise transfer the Work,
         where such license applies only to those patent claims licensable
         by such Contributor that are necessarily infringed by their
         Contribution(s) alone or by combination of their Contribution(s)
         with the Work to which such Contribution(s) was submitted. If You
         institute patent litigation against any entity (including a
         cross-claim or counterclaim in a lawsuit) alleging that the Work
         or a Contribution incorporated within the Work constitutes direct
         or contributory patent infringement, then any patent licenses
         granted to You under this License for that Work shall terminate
         as of the date such litigation is filed.

      4. Redistribution. You may reproduce and distribute copies of the
         Work or Derivative Works thereof in any medium, with or without
         modifications, and in Source or Object form, provided that You
         meet the following conditions:

         (a) You must give any other recipients of the Work or
             Derivative Works a copy of this License; and

         (b) You must cause any modified files to carry prominent notices
             stating that You changed the files; and

         (c) You must retain, in the Source form of any Derivative Works
             that You distribute, all copyright, patent, trademark, and
             attribution notices from the Source form of the Work,
             excluding those notices that do not pertain to any part of
             the Derivative Works; and

         (d) If the Work includes a "NOTICE" text file as part of its
             distribution, then any Derivative Works that You distribute must
             include a readable copy of the attribution notices contained
             within such NOTICE file, excluding those notices that do not
             pertain to any part of the Derivative Works, in at least one
             of the following places: within a NOTICE text file distributed
             as part of the Derivative Works; within the Source form or
             documentation, if provided along with the Derivative Works; or,
             within a display generated by the Derivative Works, if and
             wherever such third-party notices normally appear. The contents
             of the NOTICE file are for informational purposes only and
             do not modify the License. You may add Your own attribution
             notices within Derivative Works that You distribute, alongside
             or as an addendum to the NOTICE text from the Work, provided
             that such additional attribution notices cannot be construed
             as modifying the License.

         You may add Your own copyright statement to Your modifications and
         may provide additional or different license terms and conditions
         for use, reproduction, or distribution of Your modifications, or
         for any such Derivative Works as a whole, provided Your use,
         reproduction, and distribution of the Work otherwise complies with
         the conditions stated in this License.

      5. Submission of Contributions. Unless You explicitly state otherwise,
         any Contribution intentionally submitted for inclusion in the Work
         by You to the Licensor shall be under the terms and conditions of
         this License, without any additional terms or conditions.
         Notwithstanding the above, nothing herein shall supersede or modify
         the terms of any separate license agreement you may have executed
         with Licensor regarding such Contributions.

      6. Trademarks. This License does not grant permission to use the trade
         names, trademarks, service marks, or product names of the Licensor,
         except as required for reasonable and customary use in describing the
         origin of the Work and reproducing the content of the NOTICE file.

      7. Disclaimer of Warranty. Unless required by applicable law or
         agreed to in writing, Licensor provides the Work (and each
         Contributor provides its Contributions) on an "AS IS" BASIS,
         WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
         implied, including, without limitation, any warranties or conditions
         of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
         PARTICULAR PURPOSE. You are solely responsible for determining the
         appropriateness of using or redistributing the Work and assume any
         risks associated with Your exercise of permissions under this License.

      8. Limitation of Liability. In no event and under no legal theory,
         whether in tort (including negligence), contract, or otherwise,
         unless required by applicable law (such as deliberate and grossly
         negligent acts) or agreed to in writing, shall any Contributor be
         liable to You for damages, including any direct, indirect, special,
         incidental, or consequential damages of any character arising as a
         result of this License or out of the use or inability to use the
         Work (including but not limited to damages for loss of goodwill,
         work stoppage, computer failure or malfunction, or any and all
         other commercial damages or losses), even if such Contributor
         has been advised of the possibility of such damages.

      9. Accepting Warranty or Additional Liability. While redistributing
         the Work or Derivative Works thereof, You may choose to offer,
         and charge a fee for, acceptance of support, warranty, indemnity,
         or other liability obligations and/or rights consistent with this
         License. However, in accepting such obligations, You may act only
         on Your own behalf and on Your sole responsibility, not on behalf
         of any other Contributor, and only if You agree to indemnify,
         defend, and hold each Contributor harmless for any liability
         incurred by, or claims asserted against, such Contributor by reason
         of your accepting any such warranty or additional liability.

      END OF TERMS AND CONDITIONS

      APPENDIX: How to apply the Apache License to your work.

         To apply the Apache License to your work, attach the following
         boilerplate notice, with the fields enclosed by brackets "[]"
         replaced with your own identifying information. (Don't include
         the brackets!)  The text should be enclosed in the appropriate
         comment syntax for the file format. We also recommend that a
         file or class name and description of purpose be included on the
         same "printed page" as the copyright notice for easier
         identification within third-party archives.

                         GNU GENERAL PUBLIC LICENSE
                          Version 3, 29 June 2007

    Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
    Everyone is permitted to copy and distribute verbatim copies
    of this license document, but changing it is not allowed.

                               Preamble

     The GNU General Public License is a free, copyleft license for
   software and other kinds of works.

     The licenses for most software and other practical works are designed
   to take away your freedom to share and change the works.  By contrast,
   the GNU General Public License is intended to guarantee your freedom to
   share and change all versions of a program--to make sure it remains free
   software for all its users.  We, the Free Software Foundation, use the
   GNU General Public License for most of our software; it applies also to
   any other work released this way by its authors.  You can apply it to
   your programs, too.

     When we speak of free software, we are referring to freedom, 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
   them if you wish), that you receive source code or can get it if you
   want it, that you can change the software or use pieces of it in new
   free programs, and that you know you can do these things.

     To protect your rights, we need to prevent others from denying you
   these rights or asking you to surrender the rights.  Therefore, you have
   certain responsibilities if you distribute copies of the software, or if
   you modify it: responsibilities to respect the freedom of others.

     For example, if you distribute copies of such a program, whether
   gratis or for a fee, you must pass on to the recipients the same
   freedoms that you received.  You must make sure that they, too, receive
   or can get the source code.  And you must show them these terms so they
   know their rights.

     Developers that use the GNU GPL protect your rights with two steps:
   (1) assert copyright on the software, and (2) offer you this License
   giving you legal permission to copy, distribute and/or modify it.

     For the developers' and authors' protection, the GPL clearly explains
   that there is no warranty for this free software.  For both users' and
   authors' sake, the GPL requires that modified versions be marked as
   changed, so that their problems will not be attributed erroneously to
   authors of previous versions.

     Some devices are designed to deny users access to install or run
   modified versions of the software inside them, although the manufacturer
   can do so.  This is fundamentally incompatible with the aim of
   protecting users' freedom to change the software.  The systematic
   pattern of such abuse occurs in the area of products for individuals to
   use, which is precisely where it is most unacceptable.  Therefore, we
   have designed this version of the GPL to prohibit the practice for those
   products.  If such problems arise substantially in other domains, we
   stand ready to extend this provision to those domains in future versions
   of the GPL, as needed to protect the freedom of users.

     Finally, every program is threatened constantly by software patents.
   States should not allow patents to restrict development and use of
   software on general-purpose computers, but in those that do, we wish to
   avoid the special danger that patents applied to a free program could
   make it effectively proprietary.  To prevent this, the GPL assures that
   patents cannot be used to render the program non-free.

     The precise terms and conditions for copying, distribution and
   modification follow.

                          TERMS AND CONDITIONS

     0. Definitions.

     "This License" refers to version 3 of the GNU General Public License.

     "Copyright" also means copyright-like laws that apply to other kinds of
   works, such as semiconductor masks.

     "The Program" refers to any copyrightable work licensed under this
   License.  Each licensee is addressed as "you".  "Licensees" and
   "recipients" may be individuals or organizations.

     To "modify" a work means to copy from or adapt all or part of the work
   in a fashion requiring copyright permission, other than the making of an
   exact copy.  The resulting work is called a "modified version" of the
   earlier work or a work "based on" the earlier work.

     A "covered work" means either the unmodified Program or a work based
   on the Program.

     To "propagate" a work means to do anything with it that, without
   permission, would make you directly or secondarily liable for
   infringement under applicable copyright law, except executing it on a
   computer or modifying a private copy.  Propagation includes copying,
   distribution (with or without modification), making available to the
   public, and in some countries other activities as well.

     To "convey" a work means any kind of propagation that enables other
   parties to make or receive copies.  Mere interaction with a user through
   a computer network, with no transfer of a copy, is not conveying.

     An interactive user interface displays "Appropriate Legal Notices"
   to the extent that it includes a convenient and prominently visible
   feature that (1) displays an appropriate copyright notice, and (2)
   tells the user that there is no warranty for the work (except to the
   extent that warranties are provided), that licensees may convey the
   work under this License, and how to view a copy of this License.  If
   the interface presents a list of user commands or options, such as a
   menu, a prominent item in the list meets this criterion.

     1. Source Code.

     The "source code" for a work means the preferred form of the work
   for making modifications to it.  "Object code" means any non-source
   form of a work.

     A "Standard Interface" means an interface that either is an official
   standard defined by a recognized standards body, or, in the case of
   interfaces specified for a particular programming language, one that
   is widely used among developers working in that language.

     The "System Libraries" of an executable work include anything, other
   than the work as a whole, that (a) is included in the normal form of
   packaging a Major Component, but which is not part of that Major
   Component, and (b) serves only to enable use of the work with that
   Major Component, or to implement a Standard Interface for which an
   implementation is available to the public in source code form.  A
   "Major Component", in this context, means a major essential component
   (kernel, window system, and so on) of the specific operating system
   (if any) on which the executable work runs, or a compiler used to
   produce the work, or an object code interpreter used to run it.

     The "Corresponding Source" for a work in object code form means all
   the source code needed to generate, install, and (for an executable
   work) run the object code and to modify the work, including scripts to
   control those activities.  However, it does not include the work's
   System Libraries, or general-purpose tools or generally available free
   programs which are used unmodified in performing those activities but
   which are not part of the work.  For example, Corresponding Source
   includes interface definition files associated with source files for
   the work, and the source code for shared libraries and dynamically
   linked subprograms that the work is specifically designed to require,
   such as by intimate data communication or control flow between those
   subprograms and other parts of the work.

     The Corresponding Source need not include anything that users
   can regenerate automatically from other parts of the Corresponding
   Source.

     The Corresponding Source for a work in source code form is that
   same work.

     2. Basic Permissions.

     All rights granted under this License are granted for the term of
   copyright on the Program, and are irrevocable provided the stated
   conditions are met.  This License explicitly affirms your unlimited
   permission to run the unmodified Program.  The output from running a
   covered work is covered by this License only if the output, given its
   content, constitutes a covered work.  This License acknowledges your
   rights of fair use or other equivalent, as provided by copyright law.

     You may make, run and propagate covered works that you do not
   convey, without conditions so long as your license otherwise remains
   in force.  You may convey covered works to others for the sole purpose
   of having them make modifications exclusively for you, or provide you
   with facilities for running those works, provided that you comply with
   the terms of this License in conveying all material for which you do
   not control copyright.  Those thus making or running the covered works
   for you must do so exclusively on your behalf, under your direction
   and control, on terms that prohibit them from making any copies of
   your copyrighted material outside their relationship with you.

     Conveying under any other circumstances is permitted solely under
   the conditions stated below.  Sublicensing is not allowed; section 10
   makes it unnecessary.

     3. Protecting Users' Legal Rights From Anti-Circumvention Law.

     No covered work shall be deemed part of an effective technological
   measure under any applicable law fulfilling obligations under article
   11 of the WIPO copyright treaty adopted on 20 December 1996, or
   similar laws prohibiting or restricting circumvention of such
   measures.

     When you convey a covered work, you waive any legal power to forbid
   circumvention of technological measures to the extent such circumvention
   is effected by exercising rights under this License with respect to
   the covered work, and you disclaim any intention to limit operation or
   modification of the work as a means of enforcing, against the work's
   users, your or third parties' legal rights to forbid circumvention of
   technological measures.

     4. Conveying Verbatim Copies.

     You may convey verbatim copies of the Program's source code as you
   receive it, in any medium, provided that you conspicuously and
   appropriately publish on each copy an appropriate copyright notice;
   keep intact all notices stating that this License and any
   non-permissive terms added in accord with section 7 apply to the code;
   keep intact all notices of the absence of any warranty; and give all
   recipients a copy of this License along with the Program.

     You may charge any price or no price for each copy that you convey,
   and you may offer support or warranty protection for a fee.

     5. Conveying Modified Source Versions.

     You may convey a work based on the Program, or the modifications to
   produce it from the Program, in the form of source code under the
   terms of section 4, provided that you also meet all of these conditions:

       a) The work must carry prominent notices stating that you modified
       it, and giving a relevant date.

       b) The work must carry prominent notices stating that it is
       released under this License and any conditions added under section
       7.  This requirement modifies the requirement in section 4 to
       "keep intact all notices".

       c) You must license the entire work, as a whole, under this
       License to anyone who comes into possession of a copy.  This
       License will therefore apply, along with any applicable section 7
       additional terms, to the whole of the work, and all its parts,
       regardless of how they are packaged.  This License gives no
       permission to license the work in any other way, but it does not
       invalidate such permission if you have separately received it.

       d) If the work has interactive user interfaces, each must display
       Appropriate Legal Notices; however, if the Program has interactive
       interfaces that do not display Appropriate Legal Notices, your
       work need not make them do so.

     A compilation of a covered work with other separate and independent
   works, which are not by their nature extensions of the covered work,
   and which are not combined with it such as to form a larger program,
   in or on a volume of a storage or distribution medium, is called an
   "aggregate" if the compilation and its resulting copyright are not
   used to limit the access or legal rights of the compilation's users
   beyond what the individual works permit.  Inclusion of a covered work
   in an aggregate does not cause this License to apply to the other
   parts of the aggregate.

     6. Conveying Non-Source Forms.

     You may convey a covered work in object code form under the terms
   of sections 4 and 5, provided that you also convey the
   machine-readable Corresponding Source under the terms of this License,
   in one of these ways:

       a) Convey the object code in, or embodied in, a physical product
       (including a physical distribution medium), accompanied by the
       Corresponding Source fixed on a durable physical medium
       customarily used for software interchange.

       b) Convey the object code in, or embodied in, a physical product
       (including a physical distribution medium), accompanied by a
       written offer, valid for at least three years and valid for as
       long as you offer spare parts or customer support for that product
       model, to give anyone who possesses the object code either (1) a
       copy of the Corresponding Source for all the software in the
       product that is covered by this License, on a durable physical
       medium customarily used for software interchange, for a price no
       more than your reasonable cost of physically performing this
       conveying of source, or (2) access to copy the
       Corresponding Source from a network server at no charge.

       c) Convey individual copies of the object code with a copy of the
       written offer to provide the Corresponding Source.  This
       alternative is allowed only occasionally and noncommercially, and
       only if you received the object code with such an offer, in accord
       with subsection 6b.

       d) Convey the object code by offering access from a designated
       place (gratis or for a charge), and offer equivalent access to the
       Corresponding Source in the same way through the same place at no
       further charge.  You need not require recipients to copy the
       Corresponding Source along with the object code.  If the place to
       copy the object code is a network server, the Corresponding Source
       may be on a different server (operated by you or a third party)
       that supports equivalent copying facilities, provided you maintain
       clear directions next to the object code saying where to find the
       Corresponding Source.  Regardless of what server hosts the
       Corresponding Source, you remain obligated to ensure that it is
       available for as long as needed to satisfy these requirements.

       e) Convey the object code using peer-to-peer transmission, provided
       you inform other peers where the object code and Corresponding
       Source of the work are being offered to the general public at no
       charge under subsection 6d.

     A separable portion of the object code, whose source code is excluded
   from the Corresponding Source as a System Library, need not be
   included in conveying the object code work.

     A "User Product" is either (1) a "consumer product", which means any
   tangible personal property which is normally used for personal, family,
   or household purposes, or (2) anything designed or sold for incorporation
   into a dwelling.  In determining whether a product is a consumer product,
   doubtful cases shall be resolved in favor of coverage.  For a particular
   product received by a particular user, "normally used" refers to a
   typical or common use of that class of product, regardless of the status
   of the particular user or of the way in which the particular user
   actually uses, or expects or is expected to use, the product.  A product
   is a consumer product regardless of whether the product has substantial
   commercial, industrial or non-consumer uses, unless such uses represent
   the only significant mode of use of the product.

     "Installation Information" for a User Product means any methods,
   procedures, authorization keys, or other information required to install
   and execute modified versions of a covered work in that User Product from
   a modified version of its Corresponding Source.  The information must
   suffice to ensure that the continued functioning of the modified object
   code is in no case prevented or interfered with solely because
   modification has been made.

     If you convey an object code work under this section in, or with, or
   specifically for use in, a User Product, and the conveying occurs as
   part of a transaction in which the right of possession and use of the
   User Product is transferred to the recipient in perpetuity or for a
   fixed term (regardless of how the transaction is characterized), the
   Corresponding Source conveyed under this section must be accompanied
   by the Installation Information.  But this requirement does not apply
   if neither you nor any third party retains the ability to install
   modified object code on the User Product (for example, the work has
   been installed in ROM).

     The requirement to provide Installation Information does not include a
   requirement to continue to provide support service, warranty, or updates
   for a work that has been modified or installed by the recipient, or for
   the User Product in which it has been modified or installed.  Access to a
   network may be denied when the modification itself materially and
   adversely affects the operation of the network or violates the rules and
   protocols for communication across the network.

     Corresponding Source conveyed, and Installation Information provided,
   in accord with this section must be in a format that is publicly
   documented (and with an implementation available to the public in
   source code form), and must require no special password or key for
   unpacking, reading or copying.

     7. Additional Terms.

     "Additional permissions" are terms that supplement the terms of this
   License by making exceptions from one or more of its conditions.
   Additional permissions that are applicable to the entire Program shall
   be treated as though they were included in this License, to the extent
   that they are valid under applicable law.  If additional permissions
   apply only to part of the Program, that part may be used separately
   under those permissions, but the entire Program remains governed by
   this License without regard to the additional permissions.

     When you convey a copy of a covered work, you may at your option
   remove any additional permissions from that copy, or from any part of
   it.  (Additional permissions may be written to require their own
   removal in certain cases when you modify the work.)  You may place
   additional permissions on material, added by you to a covered work,
   for which you have or can give appropriate copyright permission.

     Notwithstanding any other provision of this License, for material you
   add to a covered work, you may (if authorized by the copyright holders of
   that material) supplement the terms of this License with terms:

       a) Disclaiming warranty or limiting liability differently from the
       terms of sections 15 and 16 of this License; or

       b) Requiring preservation of specified reasonable legal notices or
       author attributions in that material or in the Appropriate Legal
       Notices displayed by works containing it; or

       c) Prohibiting misrepresentation of the origin of that material, or
       requiring that modified versions of such material be marked in
       reasonable ways as different from the original version; or

       d) Limiting the use for publicity purposes of names of licensors or
       authors of the material; or

       e) Declining to grant rights under trademark law for use of some
       trade names, trademarks, or service marks; or

       f) Requiring indemnification of licensors and authors of that
       material by anyone who conveys the material (or modified versions of
       it) with contractual assumptions of liability to the recipient, for
       any liability that these contractual assumptions directly impose on
       those licensors and authors.

     All other non-permissive additional terms are considered "further
   restrictions" within the meaning of section 10.  If the Program as you
   received it, or any part of it, contains a notice stating that it is
   governed by this License along with a term that is a further
   restriction, you may remove that term.  If a license document contains
   a further restriction but permits relicensing or conveying under this
   License, you may add to a covered work material governed by the terms
   of that license document, provided that the further restriction does
   not survive such relicensing or conveying.

     If you add terms to a covered work in accord with this section, you
   must place, in the relevant source files, a statement of the
   additional terms that apply to those files, or a notice indicating
   where to find the applicable terms.

     Additional terms, permissive or non-permissive, may be stated in the
   form of a separately written license, or stated as exceptions;
   the above requirements apply either way.

     8. Termination.

     You may not propagate or modify a covered work except as expressly
   provided under this License.  Any attempt otherwise to propagate or
   modify it is void, and will automatically terminate your rights under
   this License (including any patent licenses granted under the third
   paragraph of section 11).

     However, if you cease all violation of this License, then your
   license from a particular copyright holder is reinstated (a)
   provisionally, unless and until the copyright holder explicitly and
   finally terminates your license, and (b) permanently, if the copyright
   holder fails to notify you of the violation by some reasonable means
   prior to 60 days after the cessation.

     Moreover, your license from a particular copyright holder is
   reinstated permanently if the copyright holder notifies you of the
   violation by some reasonable means, this is the first time you have
   received notice of violation of this License (for any work) from that
   copyright holder, and you cure the violation prior to 30 days after
   your receipt of the notice.

     Termination of your rights under this section does not terminate the
   licenses of parties who have received copies or rights from you under
   this License.  If your rights have been terminated and not permanently
   reinstated, you do not qualify to receive new licenses for the same
   material under section 10.

     9. Acceptance Not Required for Having Copies.

     You are not required to accept this License in order to receive or
   run a copy of the Program.  Ancillary propagation of a covered work
   occurring solely as a consequence of using peer-to-peer transmission
   to receive a copy likewise does not require acceptance.  However,
   nothing other than this License grants you permission to propagate or
   modify any covered work.  These actions infringe copyright if you do
   not accept this License.  Therefore, by modifying or propagating a
   covered work, you indicate your acceptance of this License to do so.

     10. Automatic Licensing of Downstream Recipients.

     Each time you convey a covered work, the recipient automatically
   receives a license from the original licensors, to run, modify and
   propagate that work, subject to this License.  You are not responsible
   for enforcing compliance by third parties with this License.

     An "entity transaction" is a transaction transferring control of an
   organization, or substantially all assets of one, or subdividing an
   organization, or merging organizations.  If propagation of a covered
   work results from an entity transaction, each party to that
   transaction who receives a copy of the work also receives whatever
   licenses to the work the party's predecessor in interest had or could
   give under the previous paragraph, plus a right to possession of the
   Corresponding Source of the work from the predecessor in interest, if
   the predecessor has it or can get it with reasonable efforts.

     You may not impose any further restrictions on the exercise of the
   rights granted or affirmed under this License.  For example, you may
   not impose a license fee, royalty, or other charge for exercise of
   rights granted under this License, and you may not initiate litigation
   (including a cross-claim or counterclaim in a lawsuit) alleging that
   any patent claim is infringed by making, using, selling, offering for
   sale, or importing the Program or any portion of it.

     11. Patents.

     A "contributor" is a copyright holder who authorizes use under this
   License of the Program or a work on which the Program is based.  The
   work thus licensed is called the contributor's "contributor version".

     A contributor's "essential patent claims" are all patent claims
   owned or controlled by the contributor, whether already acquired or
   hereafter acquired, that would be infringed by some manner, permitted
   by this License, of making, using, or selling its contributor version,
   but do not include claims that would be infringed only as a
   consequence of further modification of the contributor version.  For
   purposes of this definition, "control" includes the right to grant
   patent sublicenses in a manner consistent with the requirements of
   this License.

     Each contributor grants you a non-exclusive, worldwide, royalty-free
   patent license under the contributor's essential patent claims, to
   make, use, sell, offer for sale, import and otherwise run, modify and
   propagate the contents of its contributor version.

     In the following three paragraphs, a "patent license" is any express
   agreement or commitment, however denominated, not to enforce a patent
   (such as an express permission to practice a patent or covenant not to
   sue for patent infringement).  To "grant" such a patent license to a
   party means to make such an agreement or commitment not to enforce a
   patent against the party.

     If you convey a covered work, knowingly relying on a patent license,
   and the Corresponding Source of the work is not available for anyone
   to copy, free of charge and under the terms of this License, through a
   publicly available network server or other readily accessible means,
   then you must either (1) cause the Corresponding Source to be so
   available, or (2) arrange to deprive yourself of the benefit of the
   patent license for this particular work, or (3) arrange, in a manner
   consistent with the requirements of this License, to extend the patent
   license to downstream recipients.  "Knowingly relying" means you have
   actual knowledge that, but for the patent license, your conveying the
   covered work in a country, or your recipient's use of the covered work
   in a country, would infringe one or more identifiable patents in that
   country that you have reason to believe are valid.

     If, pursuant to or in connection with a single transaction or
   arrangement, you convey, or propagate by procuring conveyance of, a
   covered work, and grant a patent license to some of the parties
   receiving the covered work authorizing them to use, propagate, modify
   or convey a specific copy of the covered work, then the patent license
   you grant is automatically extended to all recipients of the covered
   work and works based on it.

     A patent license is "discriminatory" if it does not include within
   the scope of its coverage, prohibits the exercise of, or is
   conditioned on the non-exercise of one or more of the rights that are
   specifically granted under this License.  You may not convey a covered
   work if you are a party to an arrangement with a third party that is
   in the business of distributing software, under which you make payment
   to the third party based on the extent of your activity of conveying
   the work, and under which the third party grants, to any of the
   parties who would receive the covered work from you, a discriminatory
   patent license (a) in connection with copies of the covered work
   conveyed by you (or copies made from those copies), or (b) primarily
   for and in connection with specific products or compilations that
   contain the covered work, unless you entered into that arrangement,
   or that patent license was granted, prior to 28 March 2007.

     Nothing in this License shall be construed as excluding or limiting
   any implied license or other defenses to infringement that may
   otherwise be available to you under applicable patent law.

     12. No Surrender of Others' Freedom.

     If 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 convey a
   covered work so as to satisfy simultaneously your obligations under this
   License and any other pertinent obligations, then as a consequence you may
   not convey it at all.  For example, if you agree to terms that obligate you
   to collect a royalty for further conveying from those to whom you convey
   the Program, the only way you could satisfy both those terms and this
   License would be to refrain entirely from conveying the Program.

     13. Use with the GNU Affero General Public License.

     Notwithstanding any other provision of this License, you have
   permission to link or combine any covered work with a work licensed
   under version 3 of the GNU Affero General Public License into a single
   combined work, and to convey the resulting work.  The terms of this
   License will continue to apply to the part which is the covered work,
   but the special requirements of the GNU Affero General Public License,
   section 13, concerning interaction through a network will apply to the
   combination as such.

     14. Revised Versions of this License.

     The Free Software Foundation may publish revised and/or new versions of
   the GNU 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
   Program specifies that a certain numbered version of the GNU General
   Public License "or any later version" applies to it, you have the
   option of following the terms and conditions either of that numbered
   version or of any later version published by the Free Software
   Foundation.  If the Program does not specify a version number of the
   GNU General Public License, you may choose any version ever published
   by the Free Software Foundation.

     If the Program specifies that a proxy can decide which future
   versions of the GNU General Public License can be used, that proxy's
   public statement of acceptance of a version permanently authorizes you
   to choose that version for the Program.

     Later license versions may give you additional or different
   permissions.  However, no additional obligations are imposed on any
   author or copyright holder as a result of your choosing to follow a
   later version.

     15. Disclaimer of Warranty.

     THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
   APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
   HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "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 PROGRAM
   IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
   ALL NECESSARY SERVICING, REPAIR OR CORRECTION.

     16. Limitation of Liability.

     IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
   WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
   THE PROGRAM 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 PROGRAM (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 PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
   EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
   SUCH DAMAGES.

     17. Interpretation of Sections 15 and 16.

     If the disclaimer of warranty and limitation of liability provided
   above cannot be given local legal effect according to their terms,
   reviewing courts shall apply local law that most closely approximates
   an absolute waiver of all civil liability in connection with the
   Program, unless a warranty or assumption of liability accompanies a
   copy of the Program in return for a fee.

                        END OF TERMS AND CONDITIONS

               How to Apply These Terms to Your New Programs

     If you develop a new program, and you want it to be of the greatest
   possible use to the public, the best way to achieve this is to make it
   free software which everyone can redistribute and change under these terms.

     To do so, attach the following notices to the program.  It is safest
   to attach them to the start of each source file to most effectively
   state 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 program's name and a brief idea of what it does.>
       Copyright (C) <year>  <name of author>

       This program is free software: you can redistribute it and/or modify
       it under the terms of the GNU General Public License as published by
       the Free Software Foundation, either version 3 of the License, or
       (at your option) any later version.

       This program 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 General Public License for more details.

       You should have received a copy of the GNU General Public License
       along with this program.  If not, see <http://www.gnu.org/licenses/>.

   Also add information on how to contact you by electronic and paper mail.

     If the program does terminal interaction, make it output a short
   notice like this when it starts in an interactive mode:

       <program>  Copyright (C) <year>  <name of author>
       This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
       This is free software, and you are welcome to redistribute it
       under certain conditions; type `show c' for details.

   The hypothetical commands `show w' and `show c' should show the appropriate
   parts of the General Public License.  Of course, your program's commands
   might be different; for a GUI interface, you would use an "about box".

     You should also get your employer (if you work as a programmer) or school,
   if any, to sign a "copyright disclaimer" for the program, if necessary.
   For more information on this, and how to apply and follow the GNU GPL, see
   <http://www.gnu.org/licenses/>.

     The GNU General Public License does not permit incorporating your program
   into proprietary programs.  If your program is a subroutine library, you
   may consider it more useful to permit linking proprietary applications with
   the library.  If this is what you want to do, use the GNU Lesser General
   Public License instead of this License.  But first, please read
   <http://www.gnu.org/philosophy/why-not-lgpl.html>.

   		         GNU LESSER GENERAL PUBLIC LICENSE
                          Version 3, 29 June 2007

    Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
    Everyone is permitted to copy and distribute verbatim copies
    of this license document, but changing it is not allowed.


     This version of the GNU Lesser General Public License incorporates
   the terms and conditions of version 3 of the GNU General Public
   License, supplemented by the additional permissions listed below.

     0. Additional Definitions. 

     As used herein, "this License" refers to version 3 of the GNU Lesser
   General Public License, and the "GNU GPL" refers to version 3 of the GNU
   General Public License.

     "The Library" refers to a covered work governed by this License,
   other than an Application or a Combined Work as defined below.

     An "Application" is any work that makes use of an interface provided
   by the Library, but which is not otherwise based on the Library.
   Defining a subclass of a class defined by the Library is deemed a mode
   of using an interface provided by the Library.

     A "Combined Work" is a work produced by combining or linking an
   Application with the Library.  The particular version of the Library
   with which the Combined Work was made is also called the "Linked
   Version".

     The "Minimal Corresponding Source" for a Combined Work means the
   Corresponding Source for the Combined Work, excluding any source code
   for portions of the Combined Work that, considered in isolation, are
   based on the Application, and not on the Linked Version.

     The "Corresponding Application Code" for a Combined Work means the
   object code and/or source code for the Application, including any data
   and utility programs needed for reproducing the Combined Work from the
   Application, but excluding the System Libraries of the Combined Work.

     1. Exception to Section 3 of the GNU GPL.

     You may convey a covered work under sections 3 and 4 of this License
   without being bound by section 3 of the GNU GPL.

     2. Conveying Modified Versions.

     If you modify a copy of the Library, and, in your modifications, a
   facility refers to a function or data to be supplied by an Application
   that uses the facility (other than as an argument passed when the
   facility is invoked), then you may convey a copy of the modified
   version:

      a) under this License, provided that you make a good faith effort to
      ensure that, in the event an Application does not supply the
      function or data, the facility still operates, and performs
      whatever part of its purpose remains meaningful, or

      b) under the GNU GPL, with none of the additional permissions of
      this License applicable to that copy.

     3. Object Code Incorporating Material from Library Header Files.

     The object code form of an Application may incorporate material from
   a header file that is part of the Library.  You may convey such object
   code under terms of your choice, provided that, if the incorporated
   material is not limited to numerical parameters, data structure
   layouts and accessors, or small macros, inline functions and templates
   (ten or fewer lines in length), you do both of the following:

      a) Give prominent notice with each copy of the object code that the
      Library is used in it and that the Library and its use are
      covered by this License.

      b) Accompany the object code with a copy of the GNU GPL and this license
      document.

     4. Combined Works.

     You may convey a Combined Work under terms of your choice that,
   taken together, effectively do not restrict modification of the
   portions of the Library contained in the Combined Work and reverse
   engineering for debugging such modifications, if you also do each of
   the following:

      a) Give prominent notice with each copy of the Combined Work that
      the Library is used in it and that the Library and its use are
      covered by this License.

      b) Accompany the Combined Work with a copy of the GNU GPL and this license
      document.

      c) For a Combined Work that displays copyright notices during
      execution, include the copyright notice for the Library among
      these notices, as well as a reference directing the user to the
      copies of the GNU GPL and this license document.

      d) Do one of the following:

          0) Convey the Minimal Corresponding Source under the terms of this
          License, and the Corresponding Application Code in a form
          suitable for, and under terms that permit, the user to
          recombine or relink the Application with a modified version of
          the Linked Version to produce a modified Combined Work, in the
          manner specified by section 6 of the GNU GPL for conveying
          Corresponding Source.

          1) Use a suitable shared library mechanism for linking with the
          Library.  A suitable mechanism is one that (a) uses at run time
          a copy of the Library already present on the user's computer
          system, and (b) will operate properly with a modified version
          of the Library that is interface-compatible with the Linked
          Version. 

      e) Provide Installation Information, but only if you would otherwise
      be required to provide such information under section 6 of the
      GNU GPL, and only to the extent that such information is
      necessary to install and execute a modified version of the
      Combined Work produced by recombining or relinking the
      Application with a modified version of the Linked Version. (If
      you use option 4d0, the Installation Information must accompany
      the Minimal Corresponding Source and Corresponding Application
      Code. If you use option 4d1, you must provide the Installation
      Information in the manner specified by section 6 of the GNU GPL
      for conveying Corresponding Source.)

     5. Combined Libraries.

     You may place library facilities that are a work based on the
   Library side by side in a single library together with other library
   facilities that are not Applications and are not covered by this
   License, and convey such a combined library under terms of your
   choice, if you do both of the following:

      a) Accompany the combined library with a copy of the same work based
      on the Library, uncombined with any other library facilities,
      conveyed under the terms of this License.

      b) Give prominent notice with the combined library that part of it
      is a work based on the Library, and explaining where to find the
      accompanying uncombined form of the same work.

     6. Revised Versions of the GNU Lesser General Public License.

     The Free Software Foundation may publish revised and/or new versions
   of the GNU Lesser General Public License from time to time. Such new
   versions will be similar in spirit to the present version, but may
   differ in detail to address new problems or concerns.

     Each version is given a distinguishing version number. If the
   Library as you received it specifies that a certain numbered version
   of the GNU Lesser General Public License "or any later version"
   applies to it, you have the option of following the terms and
   conditions either of that published version or of any later version
   published by the Free Software Foundation. If the Library as you
   received it does not specify a version number of the GNU Lesser
   General Public License, you may choose any version of the GNU Lesser
   General Public License ever published by the Free Software Foundation.

     If the Library as you received it specifies that a proxy can decide
   whether future versions of the GNU Lesser General Public License shall
   apply, that proxy's public statement of acceptance of any version is
   permanent authorization for you to choose that version for the
   Library.

   --------------------------------------------------------------------------------

              SPECIAL EXCEPTION GRANTED BY COPYRIGHT HOLDERS

   As a special exception, copyright holders give you permission to link this
   library with independent modules to produce an executable, regardless of
   the license terms of these independent modules, and to copy and distribute
   the resulting executable under terms of your choice, provided that you also
   meet, for each linked independent module, the terms and conditions of
   the license of that module. An independent module is a module which is not
   derived from or based on this library. If you modify this library, you must
   extend this exception to your version of the library.

   Note: this exception relieves you of any obligations under sections 4 and 5
   of this license, and section 6 of the GNU General Public License.

   		  GNU LESSER GENERAL PUBLIC LICENSE
   		       Version 2.1, February 1999

    Copyright (C) 1991, 1999 Free Software Foundation, Inc.
    51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  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., 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:

     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!
