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.

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 an 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!


GNU General Public License v2.0 or later
========================================

GNU GENERAL PUBLIC LICENSE

Version 2, June 1991

Copyright (C) 1989, 1991 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.

Preamble
--------

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 Lesser General Public License instead.) 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 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.

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.

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.

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.

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.

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.

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

TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
---------------------------------------------------------------

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".

   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.

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.

   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 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:

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

   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.

   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.)

   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.

   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.

   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.

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:

   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,

   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,

   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.)

   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.

   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.

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.

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.

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.

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.

   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.

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.

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.

   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.

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.

NO WARRANTY

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.

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.

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 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 program's name and an idea of what it does.
    Copyright (C) yyyy 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 2 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, 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.

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

    Gnomovision version 69, Copyright (C) year name of author
    Gnomovision 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, the commands you use may be
called something other than 'show w' and 'show c'; they could even be
mouse-clicks or menu items--whatever suits your program.

You should also get your employer (if you work as a programmer) or your school,
if any, to sign a "copyright disclaimer" for the program, if necessary. Here is
a sample; alter the names:

    Yoyodyne, Inc., hereby disclaims all copyright interest in the program
    'Gnomovision' (which makes passes at compilers) written by James Hacker.
