  GNU GENERAL PUBLIC LICENSE
                       Version 2, June 1991

 Copyright (C) 1989, 1991 Free Software Foundation, Inc.
                       51 Franklin St, 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 Library 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.


                    GNU GENERAL PUBLIC LICENSE
   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.

                     END OF TERMS AND CONDITIONS


            How to Apply These Terms to Your New Programs

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

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

    This program is free software; you can redistribute it and/or modify
    it under the terms of the GNU General Public License as published by
    the Free Software Foundation; either version 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 St, 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.

  <signature of Ty Coon>, 1 April 1989
  Ty Coon, President of Vice

This General Public License does not permit incorporating your program into
proprietary programs.  If your program is a subroutine library, you may
consider it more useful to permit linking proprietary applications with the
library.  If this is what you want to do, use the GNU Library General
Public License instead of this License.


LGPL version 2.1
                  GNU LESSER GENERAL PUBLIC LICENSE
                       Version 2.1, February 1999

 Copyright (C) 1991, 1999 Free Software Foundation, Inc.
 51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  USA
 Everyone is permitted to copy and distribute verbatim copies
 of this license document, but changing it is not allowed.

[This is the first released version of the Lesser GPL.  It also counts
 as the successor of the GNU Library Public License, version 2, hence
 the version number 2.1.]

                            Preamble

  The licenses for most software are designed to take away your
freedom to share and change it.  By contrast, the GNU General Public
Licenses are intended to guarantee your freedom to share and change
free software--to make sure the software is free for all its users.

  This license, the Lesser General Public License, applies to some
specially designated software packages--typically libraries--of the
Free Software Foundation and other authors who decide to use it.  You
can use it too, but we suggest you first think carefully about whether
this license or the ordinary General Public License is the better
strategy to use in any particular case, based on the explanations below.

  When we speak of free software, we are referring to freedom of use,
not price.  Our General Public Licenses are designed to make sure that
you have the freedom to distribute copies of free software (and charge
for this service if you wish); that you receive source code or can get
it if you want it; that you can change the software and use pieces of
it in new free programs; and that you are informed that you can do
these things.

  To protect your rights, we need to make restrictions that forbid
distributors to deny you these rights or to ask you to surrender these
rights.  These restrictions translate to certain responsibilities for
you if you distribute copies of the library or if you modify it.

  For example, if you distribute copies of the library, whether gratis
or for a fee, you must give the recipients all the rights that we gave
you.  You must make sure that they, too, receive or can get the source
code.  If you link other code with the library, you must provide
complete object files to the recipients, so that they can relink them
with the library after making changes to the library and recompiling
it.  And you must show them these terms so they know their rights.

  We protect your rights with a two-step method: (1) we copyright the
library, and (2) we offer you this license, which gives you legal
permission to copy, distribute and/or modify the library.

  To protect each distributor, we want to make it very clear that
there is no warranty for the free library.  Also, if the library is
modified by someone else and passed on, the recipients should know
that what they have is not the original version, so that the original
author's reputation will not be affected by problems that might be
introduced by others.

  Finally, software patents pose a constant threat to the existence of
any free program.  We wish to make sure that a company cannot
effectively restrict the users of a free program by obtaining a
restrictive license from a patent holder.  Therefore, we insist that
any patent license obtained for a version of the library must be
consistent with the full freedom of use specified in this license.

  Most GNU software, including some libraries, is covered by the
ordinary GNU General Public License.  This license, the GNU Lesser
General Public License, applies to certain designated libraries, and
is quite different from the ordinary General Public License.  We use
this license for certain libraries in order to permit linking those
libraries into non-free programs.

  When a program is linked with a library, whether statically or using
a shared library, the combination of the two is legally speaking a
combined work, a derivative of the original library.  The ordinary
General Public License therefore permits such linking only if the
entire combination fits its criteria of freedom.  The Lesser General
Public License permits more lax criteria for linking other code with
the library.

  We call this license the "Lesser" General Public License because it
does Less to protect the user's freedom than the ordinary General
Public License.  It also provides other free software developers Less
of an advantage over competing non-free programs.  These disadvantages
are the reason we use the ordinary General Public License for many
libraries.  However, the Lesser license provides advantages in certain
special circumstances.

  For example, on rare occasions, there may be a special need to
encourage the widest possible use of a certain library, so that it becomes
a de-facto standard.  To achieve this, non-free programs must be
allowed to use the library.  A more frequent case is that a free
library does the same job as widely used non-free libraries.  In this
case, there is little to gain by limiting the free library to free
software only, so we use the Lesser General Public License.

  In other cases, permission to use a particular library in non-free
programs enables a greater number of people to use a large body of
free software.  For example, permission to use the GNU C Library in
non-free programs enables many more people to use the whole GNU
operating system, as well as its variant, the GNU/Linux operating
system.

  Although the Lesser General Public License is Less protective of the
users' freedom, it does ensure that the user of a program that is
linked with the Library has the freedom and the wherewithal to run
that program using a modified version of the Library.

  The precise terms and conditions for copying, distribution and
modification follow.  Pay close attention to the difference between a
"work based on the library" and a "work that uses the library".  The
former contains code derived from the library, whereas the latter must
be combined with the library in order to run.

                  GNU LESSER GENERAL PUBLIC LICENSE
   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION

  0. This License Agreement applies to any software library or other
program which contains a notice placed by the copyright holder or
other authorized party saying it may be distributed under the terms of
this Lesser General Public License (also called "this License").
Each licensee is addressed as "you".

  A "library" means a collection of software functions and/or data
prepared so as to be conveniently linked with application programs
(which use some of those functions and data) to form executables.

  The "Library", below, refers to any such software library or work
which has been distributed under these terms.  A "work based on the
Library" means either the Library or any derivative work under
copyright law: that is to say, a work containing the Library or a
portion of it, either verbatim or with modifications and/or translated
straightforwardly into another language.  (Hereinafter, translation is
included without limitation in the term "modification".)

  "Source code" for a work means the preferred form of the work for
making modifications to it.  For a library, complete source code means
all the source code for all modules it contains, plus any associated
interface definition files, plus the scripts used to control compilation
and installation of the library.

  Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope.  The act of
running a program using the Library is not restricted, and output from
such a program is covered only if its contents constitute a work based
on the Library (independent of the use of the Library in a tool for
writing it).  Whether that is true depends on what the Library does
and what the program that uses the Library does.

  1. You may copy and distribute verbatim copies of the Library's
complete source code as you receive it, in any medium, provided that
you conspicuously and appropriately publish on each copy an
appropriate copyright notice and disclaimer of warranty; keep intact
all the notices that refer to this License and to the absence of any
warranty; and distribute a copy of this License along with the
Library.

  You may charge a fee for the physical act of transferring a copy,
and you may at your option offer warranty protection in exchange for a
fee.

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

    a) The modified work must itself be a software library.

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

    c) You must cause the whole of the work to be licensed at no
    charge to all third parties under the terms of this License.

    d) If a facility in the modified Library refers to a function or a
    table of data to be supplied by an application program that uses
    the facility, other than as an argument passed when the facility
    is invoked, then you must make a good faith effort to ensure that,
    in the event an application does not supply such function or
    table, the facility still operates, and performs whatever part of
    its purpose remains meaningful.

    (For example, a function in a library to compute square roots has
    a purpose that is entirely well-defined independent of the
    application.  Therefore, Subsection 2d requires that any
    application-supplied function or table used by this function must
    be optional: if the application does not supply it, the square
    root function must still compute square roots.)

These requirements apply to the modified work as a whole.  If
identifiable sections of that work are not derived from the Library,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works.  But when you
distribute the same sections as part of a whole which is a work based
on the Library, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote
it.

Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Library.

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

  3. You may opt to apply the terms of the ordinary GNU General Public
License instead of this License to a given copy of the Library.  To do
this, you must alter all the notices that refer to this License, so
that they refer to the ordinary GNU General Public License, version 2,
instead of to this License.  (If a newer version than version 2 of the
ordinary GNU General Public License has appeared, then you can specify
that version instead if you wish.)  Do not make any other change in
these notices.

  Once this change is made in a given copy, it is irreversible for
that copy, so the ordinary GNU General Public License applies to all
subsequent copies and derivative works made from that copy.

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

  4. You may copy and distribute the Library (or a portion or
derivative of it, under Section 2) in object code or executable form
under the terms of Sections 1 and 2 above provided that you accompany
it with the complete corresponding machine-readable source code, which
must be distributed under the terms of Sections 1 and 2 above on a
medium customarily used for software interchange.

  If distribution of object code is made by offering access to copy
from a designated place, then offering equivalent access to copy the
source code from the same place satisfies the requirement to
distribute the source code, even though third parties are not
compelled to copy the source along with the object code.

  5. A program that contains no derivative of any portion of the
Library, but is designed to work with the Library by being compiled or
linked with it, is called a "work that uses the Library".  Such a
work, in isolation, is not a derivative work of the Library, and
therefore falls outside the scope of this License.

  However, linking a "work that uses the Library" with the Library
creates an executable that is a derivative of the Library (because it
contains portions of the Library), rather than a "work that uses the
library".  The executable is therefore covered by this License.
Section 6 states terms for distribution of such executables.

  When a "work that uses the Library" uses material from a header file
that is part of the Library, the object code for the work may be a
derivative work of the Library even though the source code is not.
Whether this is true is especially significant if the work can be
linked without the Library, or if the work is itself a library.  The
threshold for this to be true is not precisely defined by law.

  If such an object file uses only numerical parameters, data
structure layouts and accessors, and small macros and small inline
functions (ten lines or less in length), then the use of the object
file is unrestricted, regardless of whether it is legally a derivative
work.  (Executables containing this object code plus portions of the
Library will still fall under Section 6.)

  Otherwise, if the work is a derivative of the Library, you may
distribute the object code for the work under the terms of Section 6.
Any executables containing that work also fall under Section 6,
whether or not they are linked directly with the Library itself.

  6. As an exception to the Sections above, you may also combine or
link a "work that uses the Library" with the Library to produce a
work containing portions of the Library, and distribute that work
under terms of your choice, provided that the terms permit
modification of the work for the customer's own use and reverse
engineering for debugging such modifications.

  You must give prominent notice with each copy of the work that the
Library is used in it and that the Library and its use are covered by
this License.  You must supply a copy of this License.  If the work
during execution displays copyright notices, you must include the
copyright notice for the Library among them, as well as a reference
directing the user to the copy of this License.  Also, you must do one
of these things:

    a) Accompany the work with the complete corresponding
    machine-readable source code for the Library including whatever
    changes were used in the work (which must be distributed under
    Sections 1 and 2 above); and, if the work is an executable linked
    with the Library, with the complete machine-readable "work that
    uses the Library", as object code and/or source code, so that the
    user can modify the Library and then relink to produce a modified
    executable containing the modified Library.  (It is understood
    that the user who changes the contents of definitions files in the
    Library will not necessarily be able to recompile the application
    to use the modified definitions.)

    b) Use a suitable shared library mechanism for linking with the
    Library.  A suitable mechanism is one that (1) uses at run time a
    copy of the library already present on the user's computer system,
    rather than copying library functions into the executable, and (2)
    will operate properly with a modified version of the library, if
    the user installs one, as long as the modified version is
    interface-compatible with the version that the work was made with.

    c) Accompany the work with a written offer, valid for at
    least three years, to give the same user the materials
    specified in Subsection 6a, above, for a charge no more
    than the cost of performing this distribution.

    d) If distribution of the work is made by offering access to copy
    from a designated place, offer equivalent access to copy the above
    specified materials from the same place.

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

  For an executable, the required form of the "work that uses the
Library" must include any data and utility programs needed for
reproducing the executable from it.  However, as a special exception,
the materials to be distributed need not include anything that is
normally distributed (in either source or binary form) with the major
components (compiler, kernel, and so on) of the operating system on
which the executable runs, unless that component itself accompanies
the executable.

  It may happen that this requirement contradicts the license
restrictions of other proprietary libraries that do not normally
accompany the operating system.  Such a contradiction means you cannot
use both them and the Library together in an executable that you
distribute.

  7. You may place library facilities that are a work based on the
Library side-by-side in a single library together with other library
facilities not covered by this License, and distribute such a combined
library, provided that the separate distribution of the work based on
the Library and of the other library facilities is otherwise
permitted, and provided that you do these two things:

    a) Accompany the combined library with a copy of the same work
    based on the Library, uncombined with any other library
    facilities.  This must be distributed under the terms of the
    Sections above.

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

  8. You may not copy, modify, sublicense, link with, or distribute
the Library except as expressly provided under this License.  Any
attempt otherwise to copy, modify, sublicense, link with, or
distribute the Library is void, and will automatically terminate your
rights under this License.  However, parties who have received copies,
or rights, from you under this License will not have their licenses
terminated so long as such parties remain in full compliance.

  9. You are not required to accept this License, since you have not
signed it.  However, nothing else grants you permission to modify or
distribute the Library or its derivative works.  These actions are
prohibited by law if you do not accept this License.  Therefore, by
modifying or distributing the Library (or any work based on the
Library), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Library or works based on it.

  10. Each time you redistribute the Library (or any work based on the
Library), the recipient automatically receives a license from the
original licensor to copy, distribute, link with or modify the Library
subject to these terms and conditions.  You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties with
this License.

  11. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License.  If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Library at all.  For example, if a patent
license would not permit royalty-free redistribution of the Library by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Library.

If any portion of this section is held invalid or unenforceable under any
particular circumstance, the balance of the section is intended to apply,
and the section as a whole is intended to apply in other circumstances.

It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system which is
implemented by public license practices.  Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.

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

  12. If the distribution and/or use of the Library is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Library under this License may add
an explicit geographical distribution limitation excluding those countries,
so that distribution is permitted only in or among countries not thus
excluded.  In such case, this License incorporates the limitation as if
written in the body of this License.

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

Each version is given a distinguishing version number.  If the Library
specifies a version number of this License which applies to it and
"any later version", you have the option of following the terms and
conditions either of that version or of any later version published by
the Free Software Foundation.  If the Library does not specify a
license version number, you may choose any version ever published by
the Free Software Foundation.

  14. If you wish to incorporate parts of the Library into other free
programs whose distribution conditions are incompatible with these,
write to the author to ask for permission.  For software which is
copyrighted by the Free Software Foundation, write to the Free
Software Foundation; we sometimes make exceptions for this.  Our
decision will be guided by the two goals of preserving the free status
of all derivatives of our free software and of promoting the sharing
and reuse of software generally.

                            NO WARRANTY

  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.

  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
DAMAGES.

                     END OF TERMS AND CONDITIONS

           How to Apply These Terms to Your New Libraries

  If you develop a new library, and you want it to be of the greatest
possible use to the public, we recommend making it free software that
everyone can redistribute and change.  You can do so by permitting
redistribution under these terms (or, alternatively, under the terms of the
ordinary General Public License).

  To apply these terms, attach the following notices to the library.  It is
safest to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least the
"copyright" line and a pointer to where the full notice is found.

    <one line to give the library's name and a brief idea of what it does.>
    Copyright (C) <year>  <name of author>

    This library is free software; you can redistribute it and/or
    modify it under the terms of the GNU Lesser General Public
    License as published by the Free Software Foundation; either
    version 2.1 of the License, or (at your option) any later version.

    This library is distributed in the hope that it will be useful,
    but WITHOUT ANY WARRANTY; without even the implied warranty of
    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU
    Lesser General Public License for more details.

    You should have received a copy of the GNU Lesser General Public
    License along with this library; if not, write to the Free Software
    Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  USA

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

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

  Yoyodyne, Inc., hereby disclaims all copyright interest in the
  library `Frob' (a library for tweaking knobs) written by James Random Hacker.

  <signature of Ty Coon>, 1 April 1990
  Ty Coon, President of Vice

That's all there is to it!

Copy of GNU Free Documentation License, Version 1.3
                GNU Free Documentation License 
                 Version 1.3, 3 November 2008 


 Copyright (C) 2000, 2001, 2002, 2007, 2008 Free Software Foundation, Inc. 
     <http://fsf.org/> 
 Everyone is permitted to copy and distribute verbatim copies 
 of this license document, but changing it is not allowed. 

0. PREAMBLE 

The purpose of this License is to make a manual, textbook, or other 
functional and useful document "free" in the sense of freedom: to 
assure everyone the effective freedom to copy and redistribute it, 
with or without modifying it, either commercially or noncommercially. 
Secondarily, this License preserves for the author and publisher a way 
to get credit for their work, while not being considered responsible 
for modifications made by others. 

This License is a kind of "copyleft", which means that derivative 
works of the document must themselves be free in the same sense.  It 
complements the GNU General Public License, which is a copyleft 
license designed for free software. 

We have designed this License in order to use it for manuals for free 
software, because free software needs free documentation: a free 
program should come with manuals providing the same freedoms that the 
software does.  But this License is not limited to software manuals; 
it can be used for any textual work, regardless of subject matter or 
whether it is published as a printed book.  We recommend this License 
principally for works whose purpose is instruction or reference. 


1. APPLICABILITY AND DEFINITIONS 

This License applies to any manual or other work, in any medium, that 
contains a notice placed by the copyright holder saying it can be 
distributed under the terms of this License.  Such a notice grants a 
world-wide, royalty-free license, unlimited in duration, to use that 
work under the conditions stated herein.  The "Document", below, 
refers to any such manual or work.  Any member of the public is a 
licensee, and is addressed as "you".  You accept the license if you 
copy, modify or distribute the work in a way requiring permission 
under copyright law. 

A "Modified Version" of the Document means any work containing the 
Document or a portion of it, either copied verbatim, or with 
modifications and/or translated into another language. 

A "Secondary Section" is a named appendix or a front-matter section of 
the Document that deals exclusively with the relationship of the 
publishers or authors of the Document to the Document's overall 
subject (or to related matters) and contains nothing that could fall 
directly within that overall subject.  (Thus, if the Document is in 
part a textbook of mathematics, a Secondary Section may not explain 
any mathematics.)  The relationship could be a matter of historical 
connection with the subject or with related matters, or of legal, 
commercial, philosophical, ethical or political position regarding 
them. 

The "Invariant Sections" are certain Secondary Sections whose titles 
are designated, as being those of Invariant Sections, in the notice 
that says that the Document is released under this License.  If a 
section does not fit the above definition of Secondary then it is not 
allowed to be designated as Invariant.  The Document may contain zero 
Invariant Sections.  If the Document does not identify any Invariant 
Sections then there are none. 

The "Cover Texts" are certain short passages of text that are listed, 
as Front-Cover Texts or Back-Cover Texts, in the notice that says that 
the Document is released under this License.  A Front-Cover Text may 
be at most 5 words, and a Back-Cover Text may be at most 25 words. 

A "Transparent" copy of the Document means a machine-readable copy, 
represented in a format whose specification is available to the 
general public, that is suitable for revising the document 
straightforwardly with generic text editors or (for images composed of 
pixels) generic paint programs or (for drawings) some widely available 
drawing editor, and that is suitable for input to text formatters or 
for automatic translation to a variety of formats suitable for input 
to text formatters.  A copy made in an otherwise Transparent file 
format whose markup, or absence of markup, has been arranged to thwart 
or discourage subsequent modification by readers is not Transparent. 
An image format is not Transparent if used for any substantial amount 
of text.  A copy that is not "Transparent" is called "Opaque". 

Examples of suitable formats for Transparent copies include plain 
ASCII without markup, Texinfo input format, LaTeX input format, SGML 
or XML using a publicly available DTD, and standard-conforming simple 
HTML, PostScript or PDF designed for human modification.  Examples of 
transparent image formats include PNG, XCF and JPG.  Opaque formats 
include proprietary formats that can be read and edited only by 
proprietary word processors, SGML or XML for which the DTD and/or 
processing tools are not generally available, and the 
machine-generated HTML, PostScript or PDF produced by some word 
processors for output purposes only. 

The "Title Page" means, for a printed book, the title page itself, 
plus such following pages as are needed to hold, legibly, the material 
this License requires to appear in the title page.  For works in 
formats which do not have any title page as such, "Title Page" means 
the text near the most prominent appearance of the work's title, 
preceding the beginning of the body of the text. 

The "publisher" means any person or entity that distributes copies of 
the Document to the public. 

A section "Entitled XYZ" means a named subunit of the Document whose 
title either is precisely XYZ or contains XYZ in parentheses following 
text that translates XYZ in another language.  (Here XYZ stands for a 
specific section name mentioned below, such as "Acknowledgements", 
"Dedications", "Endorsements", or "History".)  To "Preserve the Title" 
of such a section when you modify the Document means that it remains a 
section "Entitled XYZ" according to this definition. 

The Document may include Warranty Disclaimers next to the notice which 
states that this License applies to the Document.  These Warranty 
Disclaimers are considered to be included by reference in this 
License, but only as regards disclaiming warranties: any other 
implication that these Warranty Disclaimers may have is void and has 
no effect on the meaning of this License. 

2. VERBATIM COPYING 

You may copy and distribute the Document in any medium, either 
commercially or noncommercially, provided that this License, the 
copyright notices, and the license notice saying this License applies 
to the Document are reproduced in all copies, and that you add no 
other conditions whatsoever to those of this License.  You may not use 
technical measures to obstruct or control the reading or further 
copying of the copies you make or distribute.  However, you may accept 
compensation in exchange for copies.  If you distribute a large enough 
number of copies you must also follow the conditions in section 3. 

You may also lend copies, under the same conditions stated above, and 
you may publicly display copies. 


3. COPYING IN QUANTITY 

If you publish printed copies (or copies in media that commonly have 
printed covers) of the Document, numbering more than 100, and the 
Document's license notice requires Cover Texts, you must enclose the 
copies in covers that carry, clearly and legibly, all these Cover 
Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on 
the back cover.  Both covers must also clearly and legibly identify 
you as the publisher of these copies.  The front cover must present 
the full title with all words of the title equally prominent and 
visible.  You may add other material on the covers in addition. 
Copying with changes limited to the covers, as long as they preserve 
the title of the Document and satisfy these conditions, can be treated 
as verbatim copying in other respects. 

If the required texts for either cover are too voluminous to fit 
legibly, you should put the first ones listed (as many as fit 
reasonably) on the actual cover, and continue the rest onto adjacent 
pages. 

If you publish or distribute Opaque copies of the Document numbering 
more than 100, you must either include a machine-readable Transparent 
copy along with each Opaque copy, or state in or with each Opaque copy 
a computer-network location from which the general network-using 
public has access to download using public-standard network protocols 
a complete Transparent copy of the Document, free of added material. 
If you use the latter option, you must take reasonably prudent steps, 
when you begin distribution of Opaque copies in quantity, to ensure 
that this Transparent copy will remain thus accessible at the stated 
location until at least one year after the last time you distribute an 
Opaque copy (directly or through your agents or retailers) of that 
edition to the public. 

It is requested, but not required, that you contact the authors of the 
Document well before redistributing any large number of copies, to 
give them a chance to provide you with an updated version of the 
Document. 
 

4. MODIFICATIONS 

You may copy and distribute a Modified Version of the Document under 
the conditions of sections 2 and 3 above, provided that you release 
the Modified Version under precisely this License, with the Modified 
Version filling the role of the Document, thus licensing distribution 
and modification of the Modified Version to whoever possesses a copy 
of it.  In addition, you must do these things in the Modified Version: 

A. Use in the Title Page (and on the covers, if any) a title distinct 
   from that of the Document, and from those of previous versions 
   (which should, if there were any, be listed in the History section 
   of the Document).  You may use the same title as a previous version 
   if the original publisher of that version gives permission. 
B. List on the Title Page, as authors, one or more persons or entities 
   responsible for authorship of the modifications in the Modified 
   Version, together with at least five of the principal authors of the 
   Document (all of its principal authors, if it has fewer than five), 
   unless they release you from this requirement. 
C. State on the Title page the name of the publisher of the 
   Modified Version, as the publisher. 
D. Preserve all the copyright notices of the Document. 
E. Add an appropriate copyright notice for your modifications 
   adjacent to the other copyright notices. 
F. Include, immediately after the copyright notices, a license notice 
   giving the public permission to use the Modified Version under the 
   terms of this License, in the form shown in the Addendum below. 
G. Preserve in that license notice the full lists of Invariant Sections 
   and required Cover Texts given in the Document's license notice. 
H. Include an unaltered copy of this License. 
I. Preserve the section Entitled "History", Preserve its Title, and add 
   to it an item stating at least the title, year, new authors, and 
   publisher of the Modified Version as given on the Title Page.  If 
   there is no section Entitled "History" in the Document, create one 
   stating the title, year, authors, and publisher of the Document as 
   given on its Title Page, then add an item describing the Modified 
   Version as stated in the previous sentence. 
J. Preserve the network location, if any, given in the Document for 
   public access to a Transparent copy of the Document, and likewise 
   the network locations given in the Document for previous versions 
   it was based on.  These may be placed in the "History" section. 
   You may omit a network location for a work that was published at 
   least four years before the Document itself, or if the original 
   publisher of the version it refers to gives permission. 
K. For any section Entitled "Acknowledgements" or "Dedications", 
   Preserve the Title of the section, and preserve in the section all 
   the substance and tone of each of the contributor acknowledgements 
   and/or dedications given therein. 
L. Preserve all the Invariant Sections of the Document, 
   unaltered in their text and in their titles.  Section numbers 
   or the equivalent are not considered part of the section titles. 
M. Delete any section Entitled "Endorsements".  Such a section 
   may not be included in the Modified Version. 
N. Do not retitle any existing section to be Entitled "Endorsements" 
   or to conflict in title with any Invariant Section. 
O. Preserve any Warranty Disclaimers. 

If the Modified Version includes new front-matter sections or 
appendices that qualify as Secondary Sections and contain no material 
copied from the Document, you may at your option designate some or all 
of these sections as invariant.  To do this, add their titles to the 
list of Invariant Sections in the Modified Version's license notice. 
These titles must be distinct from any other section titles. 

You may add a section Entitled "Endorsements", provided it contains 
nothing but endorsements of your Modified Version by various 
parties--for example, statements of peer review or that the text has 
been approved by an organization as the authoritative definition of a 
standard. 

You may add a passage of up to five words as a Front-Cover Text, and a 
passage of up to 25 words as a Back-Cover Text, to the end of the list 
of Cover Texts in the Modified Version.  Only one passage of 
Front-Cover Text and one of Back-Cover Text may be added by (or 
through arrangements made by) any one entity.  If the Document already 
includes a cover text for the same cover, previously added by you or 
by arrangement made by the same entity you are acting on behalf of, 
you may not add another; but you may replace the old one, on explicit 
permission from the previous publisher that added the old one. 

The author(s) and publisher(s) of the Document do not by this License 
give permission to use their names for publicity for or to assert or 
imply endorsement of any Modified Version. 


5. COMBINING DOCUMENTS 

You may combine the Document with other documents released under this 
License, under the terms defined in section 4 above for modified 
versions, provided that you include in the combination all of the 
Invariant Sections of all of the original documents, unmodified, and 
list them all as Invariant Sections of your combined work in its 
license notice, and that you preserve all their Warranty Disclaimers. 

The combined work need only contain one copy of this License, and 
multiple identical Invariant Sections may be replaced with a single 
copy.  If there are multiple Invariant Sections with the same name but 
different contents, make the title of each such section unique by 
adding at the end of it, in parentheses, the name of the original 
author or publisher of that section if known, or else a unique number. 
Make the same adjustment to the section titles in the list of 
Invariant Sections in the license notice of the combined work. 

In the combination, you must combine any sections Entitled "History" 
in the various original documents, forming one section Entitled 
"History"; likewise combine any sections Entitled "Acknowledgements", 
and any sections Entitled "Dedications".  You must delete all sections 
Entitled "Endorsements". 


6. COLLECTIONS OF DOCUMENTS 

You may make a collection consisting of the Document and other 
documents released under this License, and replace the individual 
copies of this License in the various documents with a single copy 
that is included in the collection, provided that you follow the rules 
of this License for verbatim copying of each of the documents in all 
other respects. 

You may extract a single document from such a collection, and 
distribute it individually under this License, provided you insert a 
copy of this License into the extracted document, and follow this 
License in all other respects regarding verbatim copying of that 
document. 


7. AGGREGATION WITH INDEPENDENT WORKS 

A compilation of the Document or its derivatives with other separate 
and independent documents or works, in or on a volume of a storage or 
distribution medium, is called an "aggregate" if the copyright 
resulting from the compilation is not used to limit the legal rights 
of the compilation's users beyond what the individual works permit. 
When the Document is included in an aggregate, this License does not 
apply to the other works in the aggregate which are not themselves 
derivative works of the Document. 

If the Cover Text requirement of section 3 is applicable to these 
copies of the Document, then if the Document is less than one half of 
the entire aggregate, the Document's Cover Texts may be placed on 
covers that bracket the Document within the aggregate, or the 
electronic equivalent of covers if the Document is in electronic form. 
Otherwise they must appear on printed covers that bracket the whole 
aggregate. 


8. TRANSLATION 

Translation is considered a kind of modification, so you may 
distribute translations of the Document under the terms of section 4. 
Replacing Invariant Sections with translations requires special 
permission from their copyright holders, but you may include 
translations of some or all Invariant Sections in addition to the 
original versions of these Invariant Sections.  You may include a 
translation of this License, and all the license notices in the 
Document, and any Warranty Disclaimers, provided that you also include 
the original English version of this License and the original versions 
of those notices and disclaimers.  In case of a disagreement between 
the translation and the original version of this License or a notice 
or disclaimer, the original version will prevail. 

If a section in the Document is Entitled "Acknowledgements", 
"Dedications", or "History", the requirement (section 4) to Preserve 
its Title (section 1) will typically require changing the actual 
title. 


9. TERMINATION 

You may not copy, modify, sublicense, or distribute the Document 
except as expressly provided under this License.  Any attempt 
otherwise to copy, modify, sublicense, or distribute it is void, and 
will automatically terminate your rights under this License. 

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

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

Termination of your rights under this section does not terminate the 
licenses of parties who have received copies or rights from you under 
this License.  If your rights have been terminated and not permanently 
reinstated, receipt of a copy of some or all of the same material does 
not give you any rights to use it. 


10. FUTURE REVISIONS OF THIS LICENSE 

The Free Software Foundation may publish new, revised versions of the 
GNU Free Documentation 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.  See 
http://www.gnu.org/copyleft/. 

Each version of the License is given a distinguishing version number. 
If the Document specifies that a particular numbered version of this 
License "or any later version" applies to it, you have the option of 
following the terms and conditions either of that specified version or 
of any later version that has been published (not as a draft) by the 
Free Software Foundation.  If the Document does not specify a version 
number of this License, you may choose any version ever published (not 
as a draft) by the Free Software Foundation.  If the Document 
specifies that a proxy can decide which future versions of this 
License can be used, that proxy's public statement of acceptance of a 
version permanently authorizes you to choose that version for the 
Document. 

11. RELICENSING 

"Massive Multiauthor Collaboration Site" (or "MMC Site") means any 
World Wide Web server that publishes copyrightable works and also 
provides prominent facilities for anybody to edit those works.  A 
public wiki that anybody can edit is an example of such a server.  A 
"Massive Multiauthor Collaboration" (or "MMC") contained in the site 
means any set of copyrightable works thus published on the MMC site. 

"CC-BY-SA" means the Creative Commons Attribution-Share Alike 3.0 
license published by Creative Commons Corporation, a not-for-profit 
corporation with a principal place of business in San Francisco, 
California, as well as future copyleft versions of that license 
published by that same organization. 

"Incorporate" means to publish or republish a Document, in whole or in 
part, as part of another Document. 

An MMC is "eligible for relicensing" if it is licensed under this 
License, and if all works that were first published under this License 
somewhere other than this MMC, and subsequently incorporated in whole or 
in part into the MMC, (1) had no cover texts or invariant sections, and 
(2) were thus incorporated prior to November 1, 2008. 

The operator of an MMC Site may republish an MMC contained in the site 
under CC-BY-SA on the same site at any time before August 1, 2009, 
provided the MMC is eligible for relicensing. 


ADDENDUM: How to use this License for your documents 

To use this License in a document you have written, include a copy of 
the License in the document and put the following copyright and 
license notices just after the title page: 

    Copyright (c)  YEAR  YOUR NAME. 
    Permission is granted to copy, distribute and/or modify this document 
    under the terms of the GNU Free Documentation License, Version 1.3 
    or any later version published by the Free Software Foundation; 
    with no Invariant Sections, no Front-Cover Texts, and no Back-Cover Texts. 
    A copy of the license is included in the section entitled "GNU 
    Free Documentation License". 

If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts, 
replace the "with...Texts." line with this: 

    with the Invariant Sections being LIST THEIR TITLES, with the 
    Front-Cover Texts being LIST, and with the Back-Cover Texts being LIST. 

If you have Invariant Sections without Cover Texts, or some other 
combination of the three, merge those two alternatives to suit the 
situation. 

If your document contains nontrivial examples of program code, we 
recommend releasing these examples in parallel under your choice of 
free software license, such as the GNU General Public License, 
to permit their use in free software.
