  <title>Third-party materials and licenses</title>

  <para>VirtualBox incorporates materials from several Open Source software
  projects. Therefore the use of these materials by VirtualBox is governed by
  different Open Source licenses. This document reproduces these licenses and
  provides a list of the materials used and their respective licensing
  conditions. Section 1 contains a list of the materials used. Section 2
  reproduces the applicable Open Source licenses. For each material, a
  reference to its license is provided.</para>

  <para>The source code for the materials listed below as well as the rest of
  the VirtualBox code which is released as open source are available at <ulink
  url="http://www.virtualbox.org">http://www.virtualbox.org</ulink>, both as
  tarballs for particular releases and as a live SVN repository.</para>

      <title>GNU General Public License (GPL)</title>

      <para>GNU GENERAL PUBLIC LICENSE Version 2, June 1991</para>

      <para>Copyright (C) 1989, 1991 Free Software Foundation, Inc.</para>

      <para>51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA</para>

      <para>Everyone is permitted to copy and distribute verbatim copies of
      this license document, but changing it is not allowed.</para>

      <para>Preamble</para>

      <para>The licenses for most software are designed to take away your
      freedom to share and change it. By contrast, the GNU General Public
      License is intended to guarantee your freedom to share and change free
      software--to make sure the software is free for all its users. This
      General Public License applies to most of the Free Software Foundation's
      software and to any other program whose authors commit to using it.
      (Some other Free Software Foundation software is covered by the GNU
      Library General Public License instead.) You can apply it to your
      programs, too.</para>

      <para>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
      this service 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.</para>

      <para>To protect your rights, we need to make restrictions that forbid
      anyone to deny you these rights or to ask you to surrender the rights.
      These restrictions translate to certain responsibilities for you if you
      distribute copies of the software, or if you modify it.</para>

      <para>For example, if you distribute copies of such a program, whether
      gratis or for a fee, you must give the recipients all the rights that
      you have. 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.</para>

      <para>We protect your rights with two steps: (1) copyright the software,
      and (2) offer you this license which gives you legal permission to copy,
      distribute and/or modify the software.</para>

      <para>Also, for each author's protection and ours, we want to make
      certain that everyone understands that there is no warranty for this
      free software. If the software is modified by someone else and passed
      on, we want its recipients to know that what they have is not the
      original, so that any problems introduced by others will not reflect on
      the original authors' reputations.</para>

      <para>Finally, any free program is threatened constantly by software
      patents. We wish to avoid the danger that redistributors of a free
      program will individually obtain patent licenses, in effect making the
      program proprietary. To prevent this, we have made it clear that any
      patent must be licensed for everyone's free use or not licensed at
      all.</para>

      <para>The precise terms and conditions for copying, distribution and
      modification follow.</para>

      <para>GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING,
      DISTRIBUTION AND MODIFICATION</para>

      <para>0. This License applies to any program or other work which
      contains a notice placed by the copyright holder saying it may be
      distributed under the terms of this General Public License. The
      "Program", below, refers to any such program or work, and a "work based
      on the Program" means either the Program or any derivative work under
      copyright law: that is to say, a work containing the Program or a
      portion of it, either verbatim or with modifications and/or translated
      into another language. (Hereinafter, translation is included without
      limitation in the term "modification".) Each licensee is addressed as
      "you".</para>

      <para>Activities other than copying, distribution and modification are
      not covered by this License; they are outside its scope. The act of
      running the Program is not restricted, and the output from the Program
      is covered only if its contents constitute a work based on the Program
      (independent of having been made by running the Program). Whether that
      is true depends on what the Program does.</para>

      <para>1. You may copy and distribute 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 and disclaimer of warranty; keep intact all the notices
      that refer to this License and to the absence of any warranty; and give
      any other recipients of the Program a copy of this License along with
      the Program.</para>

      <para>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.</para>

      <para>2. You may modify your copy or copies of the Program or any
      portion of it, thus forming a work based on the Program, and copy and
      distribute such modifications or work under the terms of Section 1
      above, provided that you also meet all of these conditions:</para>

      <para>a) You must cause the modified files to carry prominent notices
      stating that you changed the files and the date of any change.</para>

      <para>b) You must cause any work that you distribute or publish, that in
      whole or in part contains or is derived from the Program or any part
      thereof, to be licensed as a whole at no charge to all third parties
      under the terms of this License.</para>

      <para>c) If the modified program normally reads commands interactively
      when run, you must cause it, when started running for such interactive
      use in the most ordinary way, to print or display an announcement
      including an appropriate copyright notice and a notice that there is no
      warranty (or else, saying that you provide a warranty) and that users
      may redistribute the program under these conditions, and telling the
      user how to view a copy of this License. (Exception: if the Program
      itself is interactive but does not normally print such an announcement,
      your work based on the Program is not required to print an
      announcement.)</para>

      <para>These requirements apply to the modified work as a whole. If
      identifiable sections of that work are not derived from the Program, 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 Program, 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.</para>

      <para>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 Program.</para>

      <para>In addition, mere aggregation of another work not based on the
      Program with the Program (or with a work based on the Program) on a
      volume of a storage or distribution medium does not bring the other work
      under the scope of this License.</para>

      <para>3. You may copy and distribute the Program (or a work based on it,
      under Section 2) in object code or executable form under the terms of
      Sections 1 and 2 above provided that you also do one of the
      following:</para>

      <para>a) 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;
      or,</para>

      <para>b) Accompany it with a written offer, valid for at least three
      years, to give any third party, for a charge no more than your cost of
      physically performing source distribution, a complete machine-readable
      copy of the corresponding source code, to be distributed under the terms
      of Sections 1 and 2 above on a medium customarily used for software
      interchange; or,</para>

      <para>c) Accompany it with the information you received as to the offer
      to distribute corresponding source code. (This alternative is allowed
      only for noncommercial distribution and only if you received the program
      in object code or executable form with such an offer, in accord with
      Subsection b above.)</para>

      <para>The source code for a work means the preferred form of the work
      for making modifications to it. For an executable work, 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 executable. However, as a special
      exception, the source code 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.</para>

      <para>If distribution of executable or 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 counts as distribution of
      the source code, even though third parties are not compelled to copy the
      source along with the object code.</para>

      <para>4. You may not copy, modify, sublicense, or distribute the Program
      except as expressly provided under this License. Any attempt otherwise
      to copy, modify, sublicense or distribute the Program 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.</para>

      <para>5. 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 Program or its derivative works. These actions are
      prohibited by law if you do not accept this License. Therefore, by
      modifying or distributing the Program (or any work based on the
      Program), you indicate your acceptance of this License to do so, and all
      its terms and conditions for copying, distributing or modifying the
      Program or works based on it.</para>

      <para>6. Each time you redistribute the Program (or any work based on
      the Program), the recipient automatically receives a license from the
      original licensor to copy, distribute or modify the Program 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 to this
      License.</para>

      <para>7. 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 Program at all. For example, if a patent
      license would not permit royalty-free redistribution of the Program 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 Program.</para>

      <para>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.</para>

      <para>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.</para>

      <para>This section is intended to make thoroughly clear what is believed
      to be a consequence of the rest of this License.</para>

      <para>8. If the distribution and/or use of the Program is restricted in
      certain countries either by patents or by copyrighted interfaces, the
      original copyright holder who places the Program 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.</para>

      <para>9. The Free Software Foundation may publish revised and/or new
      versions of the 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.</para>

      <para>Each version is given a distinguishing version number. If the
      Program 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 Program does not specify a version
      number of this License, you may choose any version ever published by the
      Free Software Foundation.</para>

      <para>10. If you wish to incorporate parts of the Program into other
      free programs whose distribution conditions are different, 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.</para>

      <para>NO WARRANTY</para>

      <para>11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, 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.</para>

      <para>12. 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 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.</para>

      <para>GNU LESSER GENERAL PUBLIC LICENSE Version 2.1, February
      1999</para>

      <para>Copyright (C) 1991, 1999 Free Software Foundation, Inc. 59 Temple
      Place, Suite 330, Boston, MA 02111-1307 USA Everyone is permitted to
      copy and distribute verbatim copies of this license document, but
      changing it is not allowed.</para>

      <para>[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.]</para>

      <para>Preamble</para>

      <para>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.</para>

      <para>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.</para>

      <para>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.</para>

      <para>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.</para>

      <para>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.</para>

      <para>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.</para>

      <para>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.</para>

      <para>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.</para>

      <para>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.</para>

      <para>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.</para>

      <para>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.</para>

      <para>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.</para>

      <para>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.</para>

      <para>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.</para>

      <para>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.</para>

      <para>GNU LESSER GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR
      COPYING, DISTRIBUTION AND MODIFICATION</para>

      <para>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".</para>

      <para>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.</para>

      <para>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".)</para>

      <para>"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.</para>

      <para>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.</para>

      <para>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.</para>

      <para>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.</para>

      <para>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:</para>

      <para>a) The modified work must itself be a software library.</para>

      <para>b) You must cause the files modified to carry prominent notices
      stating that you changed the files and the date of any change.</para>

      <para>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.</para>

      <para>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.</para>

      <para>(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.)</para>

      <para>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.</para>

      <para>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.</para>

      <para>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.</para>

      <para>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.</para>

      <para>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.</para>

      <para>This option is useful when you wish to copy part of the code of
      the Library into a program that is not a library.</para>

      <para>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.</para>

      <para>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.</para>

      <para>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.</para>

      <para>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.</para>

      <para>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.</para>

      <para>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.</para>

      <para>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.</para>

      <para>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:</para>

      <para>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.)</para>

      <para>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.</para>

      <para>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.</para>

      <para>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.</para>

      <para>e) Verify that the user has already received a copy of these
      materials or that you have already sent this user a copy.</para>

      <para>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.</para>

      <para>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.</para>

      <para>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:</para>

      <para>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.</para>

      <para>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.</para>

      <para>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.</para>

      <para>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.</para>

      <para>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.</para>

      <para>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.</para>

      <para>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.</para>

      <para>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.</para>

      <para>This section is intended to make thoroughly clear what is believed
      to be a consequence of the rest of this License.</para>

      <para>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.</para>

      <para>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.</para>

      <para>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.</para>

      <para>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.</para>

      <para>NO WARRANTY</para>

      <para>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.</para>

      <para>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.</para>

      <para>3. Distribution Obligations.</para>

      <para>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.</para>

      <para>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.</para>

      <para>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.</para>

      <para>3.4. Intellectual Property Matters</para>

      <para>(a) Third Party Claims. If Contributor has knowledge that a
      license under a third party's intellectual property rights is required
      to exercise the rights granted by such Contributor under Sections 2.1 or
      2.2, Contributor 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 Contributor obtains such knowledge after the Modification is
      made available as described in Section 3.2, Contributor shall promptly
      modify the LEGAL file in all copies Contributor makes 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.</para>

      <para>(b) Contributor APIs. If Contributor's Modifications include an
      application programming interface and Contributor has knowledge of
      patent licenses which are reasonably necessary to implement that API,
      Contributor must also include this information in the LEGAL file.</para>

      <para>3.5. Required Notices. You must duplicate the notice in Exhibit A
      in each file of the Source Code. 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)
      where a user would be likely to look for such a notice. If You created
      one or more Modification(s) You may add your name as a Contributor to
      the notice described in Exhibit A. You must also duplicate this License
      in any documentation for the Source Code where You describe recipients'
      rights or ownership rights relating to Covered Code. 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.</para>

      <para>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 or ownership rights 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.</para>

      <para>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.</para>

      <para>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, judicial
      order, 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.</para>

      <para>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.</para>

      <para>6. Versions of the License.</para>

      <para>6.1. New Versions. Netscape Communications Corporation
      ("Netscape") may publish revised and/or new versions of the License from
      time to time. Each version will be given a distinguishing version
      number.</para>

      <para>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 Netscape. No one other than Netscape has the right to
      modify the terms applicable to Covered Code created under this
      License.</para>

      <para>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 "Mozilla", "MOZILLAPL", "MOZPL",
      "Netscape", "MPL", "NPL" or any confusingly similar phrase do not appear
      in your license (except to note that your license differs from this
      License) and (b) otherwise make it clear that Your version of the
      license contains terms which differ from the Mozilla Public License and
      Netscape 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.)</para>

      <para>7. DISCLAIMER OF WARRANTY.</para>

      <para>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.</para>

      <para>8. TERMINATION.</para>

      <para>8.1. 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.</para>

      <para>8.2. If You initiate litigation by asserting a patent infringement
      claim (excluding declaratory judgment actions) against Initial Developer
      or a Contributor (the Initial Developer or Contributor against whom You
      file such action is referred to as "Participant") alleging that:</para>

      <para>(a) such Participant's Contributor Version directly or indirectly
      infringes any patent, then any and all rights granted by such
      Participant to You under Sections 2.1 and/or 2.2 of this License shall,
      upon 60 days notice from Participant terminate prospectively, unless if
      within 60 days after receipt of notice You either: (i) agree in writing
      to pay Participant a mutually agreeable reasonable royalty for Your past
      and future use of Modifications made by such Participant, or (ii)
      withdraw Your litigation claim with respect to the Contributor Version
      against such Participant. If within 60 days of notice, a reasonable
      royalty and payment arrangement are not mutually agreed upon in writing
      by the parties or the litigation claim is not withdrawn, the rights
      granted by Participant to You under Sections 2.1 and/or 2.2
      automatically terminate at the expiration of the 60 day notice period
      specified above.</para>

      <para>(b) any software, hardware, or device, other than such
      Participant's Contributor Version, directly or indirectly infringes any

      <para>8.3. If You assert a patent infringement claim against Participant
      alleging that such Participant's Contributor Version directly or
      indirectly infringes any patent where such claim is resolved (such as by
      license or settlement) prior to the initiation of patent infringement
      litigation, then the reasonable value of the licenses granted by such
      Participant under Sections 2.1 or 2.2 shall be taken into account in
      determining the amount or value of any payment or license.</para>

      <para>8.4. In the event of termination under Sections 8.1 or 8.2 above,
      all end user license agreements (excluding distributors and resellers)

      <para>9. LIMITATION OF LIABILITY. UNDER NO CIRCUMSTANCES AND UNDER NO
      LEGAL THEORY, WHETHER TORT (INCLUDING NEGLIGENCE), CONTRACT, OR
      OTHERWISE, SHALL YOU, THE INITIAL DEVELOPER, ANY OTHER CONTRIBUTOR, OR
      ANY DISTRIBUTOR OF COVERED CODE, OR ANY SUPPLIER OF ANY OF SUCH PARTIES,
      BE LIABLE TO ANY 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

      APPLICABLE LAW PROHIBITS SUCH LIMITATION. SOME JURISDICTIONS DO NOT
      ALLOW THE EXCLUSION OR LIMITATION OF INCIDENTAL OR CONSEQUENTIAL
      DAMAGES, SO THIS EXCLUSION AND LIMITATION MAY NOT APPLY TO YOU.</para>

      <para>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.</para>

      <para>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 California 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 United States of
      America, any litigation relating to this License shall be subject to the
      jurisdiction of the Federal Courts of the Northern District of
      California, with venue lying in Santa Clara County, California, with the
      losing party responsible for costs, including without limitation, court
      costs and reasonable attorneys' fees and expenses. The application of
      the United Nations Convention on Contracts for the International Sale of
      Goods is expressly excluded. Any law or regulation which provides that
      the language of a contract shall be construed against the drafter shall
      not apply to this License.</para>

      <para>12. RESPONSIBILITY FOR CLAIMS. As between Initial Developer and
      the Contributors, each party is responsible for claims and damages
      arising, directly or indirectly, out of its utilization of rights under
      this License and You agree to work with Initial Developer and
      Contributors to distribute such responsibility on an equitable basis.
      Nothing herein is intended or shall be deemed to constitute any
      admission of liability.</para>

      <para>13. MULTIPLE-LICENSED CODE. Initial Developer may designate
      portions of the Covered Code as "Multiple-Licensed". "Multiple-Licensed"
      means that the Initial Developer permits you to utilize portions of the
      Covered Code under Your choice of the NPL or the alternative licenses,
      if any, specified by the Initial Developer in the file described in

      <para>(c)</para>

      <para>(d)</para>

      <para>3 DISTRIBUTION OBLIGATIONS.</para>

      <para>3.1. Application of License.</para>

      <para>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.</para>

      <para>3.2. Availability of Source Code.</para>

      <para>Any Modification created by You will be provided to the Initial
      Developer in Source Code form and are subject to the terms of the
      License. 3.3. Description of Modifications.</para>

      <para>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.</para>

      <para>3.4. Intellectual Property Matters.</para>

      <para>(a) Third Party Claims. If Contributor has knowledge that a
      license under a third party's intellectual property rights is required
      to exercise the rights granted by such Contributor under Sections 2.1 or
      2.2, Contributor 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 Contributor obtains such knowledge after the Modification is
      made available as described in Section 3.2, Contributor shall promptly
      modify the LEGAL file in all copies Contributor makes 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.</para>

      <para>(b) Contributor APIs. If Contributor's Modifications include an
      application programming interface and Contributor has knowledge of
      patent licenses which are reasonably necessary to implement that API,
      Contributor must also include this information in the LEGAL file.</para>

      <para>(c) Representations. Contributor represents that, except as
      disclosed pursuant to Section 3.4(a) above, Contributor believes that
      Contributor's Modifications are Contributor's original creation(s)
      and/or Contributor has sufficient rights to grant the rights conveyed by
      this License.</para>

      <para>3.5. Required Notices. You must duplicate the notice in Exhibit A
      in each file of the Source Code. 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)
      where a user would be likely to look for such a notice. If You created
      one or more Modification(s) You may add your name as a Contributor to
      the notice described in Exhibit A. You must also duplicate this License
      in any documentation for the Source Code where You describe recipients'
      rights or ownership rights relating to Covered Code. 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.</para>

      <para>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. You may distribute the
      Executable version of Covered Code or ownership rights 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. If you distribute executable
      versions containing Covered Code as part of a product, you must
      reproduce the notice in Exhibit B in the documentation and/or other
      materials provided with the product.</para>

      <para>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.</para>

      <para>3.8. Restrictions. You may not remove any product identification,
      copyright, proprietary notices or labels from gSOAP.</para>

      <para>4 INABILITY TO COMPLY DUE TO STATUTE OR REGULATION.</para>

      <para>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, judicial order, 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.</para>

      <para>5 APPLICATION OF THIS LICENSE.</para>

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

      <para>6 VERSIONS OF THE LICENSE.</para>

      <para>6.1. New Versions.</para>

      <para>Grantor may publish revised and/or new versions of the License
      from time to time. Each version will be given a distinguishing version
      number.</para>

      <para>6.2. Effect of New Versions.</para>

      <para>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.</para>

      <para>6.3. Derivative Works.</para>

      <para>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 phrase "gSOAP" or any confusingly similar phrase do not appear in
      your license (except to note that your license differs from this
      License) and (b) otherwise make it clear that Your version of the
      license contains terms which differ from the gSOAP 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.)</para>

      WARRANTY CONSTITUTES AN ESSENTIAL PART OF THIS LICENSE. NO USE OF ANY
      COVERED CODE IS AUTHORIZED HEREUNDER EXCEPT UNDER THIS
      DISCLAIMER.</para>

      <para>8 TERMINATION.</para>

      <para>8.1.</para>

      <para>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.</para>

      <para>8.2.</para>

      <para>8.3.</para>

      <para>If You assert a patent infringement claim against Participant
      alleging that such Participant's Contributor Version directly or
      indirectly infringes any patent where such claim is resolved (such as by
      license or settlement) prior to the initiation of patent infringement
      litigation, then the reasonable value of the licenses granted by such
      Participant under Sections 2.1 or 2.2 shall be taken into account in
      determining the amount or value of any payment or license.</para>

      <para>8.4. In the event of termination under Sections 8.1 or 8.2 above,
      all end user license agreements (excluding distributors and resellers)
      which have been validly granted by You or any distributor hereunder

      <para>UNDER NO CIRCUMSTANCES AND UNDER NO LEGAL THEORY, WHETHER TORT
      (INCLUDING NEGLIGENCE), CONTRACT, OR OTHERWISE, SHALL YOU, THE INITIAL
      DEVELOPER, ANY OTHER CONTRIBUTOR, OR ANY DISTRIBUTOR OF COVERED CODE, OR
      ANY SUPPLIER OF ANY OF SUCH PARTIES, BE LIABLE TO ANY PERSON FOR ANY

      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

      ansi2knr.c is NOT covered by the above copyright and conditions, but instead
      by the usual distribution terms of the Free Software Foundation; principally,
      that you must include source code if you redistribute it.  (See the file
      ansi2knr.c for full details.)  However, since ansi2knr.c is not needed as part
      of any program generated from the IJG code, this does not limit you more than
      the foregoing paragraphs do.</para>

      <para>The Unix configuration script "configure" was produced with GNU Autoconf.
      It is copyright by the Free Software Foundation but is freely distributable.
      The same holds for its supporting scripts (config.guess, config.sub,

      but is also freely distributable.</para>

      <para>The IJG distribution formerly included code to read and write GIF files.
      To avoid entanglement with the Unisys LZW patent, GIF reading support has
      been removed altogether, and the GIF writer has been simplified to produce
      "uncompressed GIFs".  This technique does not use the LZW algorithm; the
      resulting GIF files are larger than usual, but are readable by all standard
      GIF decoders.</para>

        The FLTK library and included programs are provided under the terms
        of the GNU Library General Public License (LGPL) with the following
        exceptions:

            Modifications to the FLTK configure script, config
            header file, and makefiles by themselves to support
            a specific platform do not constitute a modified or
            derivative work.
          </para>
          <para>
            The authors do request that such modifications be
            contributed to the FLTK project - send all contributions
            through the "Software Trouble Report" on the following page:

          <para>
            Static linking of applications and widgets to the
            FLTK library does not constitute a derivative work
            and does not require the author to provide source
            code for the application or widget, use the shared
            FLTK libraries, or link their applications or
            widgets against a user-supplied version of FLTK.
          </para>
          <para>
            If you link the application or widget to a modified
            version of FLTK, then the changes to FLTK must be
            provided under the terms of the LGPL in sections
            1, 2, and 4.

            You do not have to provide a copy of the FLTK license
            with programs that are linked to the FLTK library, nor
            do you have to identify the FLTK license in your
            program or documentation as required by section 6
            of the LGPL.
          </para>
          <para>
            However, programs must still identify their use of FLTK.
            The following example statement can be included in user
            documentation to satisfy this requirement:

        <para>
          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.
        </para>
        <para>
          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.
        </para>
        <para>
          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:

              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
