                    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.
                    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 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.
  <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  Lesser General
Public License instead of  this License.
                  GNU LESSER  GENERAL PUBLIC LICENSE
                       Version  2.1, February 1999
 Copyright (C) 1991, 1999 Free Software  Foundation, Inc.
 51 Franklin Street, Fifth Floor, Boston,  MA  02110-1301  USA
 Everyone is permitted to copy and distribute  verbatim copies
 of this license document, but changing it is  not allowed.
[This is the first  released version of the Lesser GPL.  It  also counts
 as the successor of the GNU Library Public  License, version 2, hence
 the version number 2.1.]
Preamble
  The licenses for most software are designed  to take away your
freedom to share and  change it.  By contrast, the GNU General  Public
Licenses are intended to  guarantee your freedom to share and change
free software--to make  sure the software is free for all its users.
  This license, the Lesser General Public  License, applies to some
specially designated  software packages--typically libraries--of the
Free Software Foundation  and other authors who decide to use it.   You
can use it too, but we  suggest you first think carefully about whether
this license or the  ordinary General Public License is the better
strategy to use in any  particular case, based on the explanations below.
  When we speak of free software, we are  referring to freedom of use,
not price.  Our General Public Licenses are designed to  make sure that
you have the freedom to  distribute copies of free software (and charge
for this service if you  wish); that you receive source code or can get
it if you want it; that  you can change the software and use pieces of
it in new free programs;  and that you are informed that you can do
these things.
  To protect your rights, we need to make  restrictions that forbid
distributors to deny you  these rights or to ask you to surrender these
rights.  These restrictions translate to certain  responsibilities for
you if you distribute  copies of the library or if you modify it.
  For example, if you distribute copies of the  library, whether gratis
or for a fee, you must  give the recipients all the rights that we gave
you.  You must make sure that they, too, receive or  can get the source
code.  If you link other code with the library, you  must provide
complete object files to  the recipients, so that they can relink them
with the library after  making changes to the library and recompiling
it.  And you must show them these terms so they  know their rights.
  We protect your rights with a two-step  method: (1) we copyright the
library, and (2) we offer  you this license, which gives you legal
permission to copy,  distribute and/or modify the library.
  To protect each distributor, we want to make  it very clear that
there is no warranty for  the free library.  Also, if the library  is
modified by someone else  and passed on, the recipients should know
that what they have is not  the original version, so that the original
author's reputation will  not be affected by problems that might be
introduced by others.
  Finally, software patents pose a constant  threat to the existence of
any free program.  We wish to make sure that a company cannot
effectively restrict the  users of a free program by obtaining a
restrictive license from a  patent holder.  Therefore, we insist that
any patent license  obtained for a version of the library must be
consistent with the full  freedom of use specified in this license.
  Most GNU software, including some libraries,  is covered by the
ordinary GNU General  Public License.  This license, the GNU  Lesser
General Public License,  applies to certain designated libraries, and
is quite different from  the ordinary General Public License.  We  use
this license for certain  libraries in order to permit linking those
libraries into non-free  programs.
  When a program is linked with a library,  whether statically or using
a shared library, the  combination of the two is legally speaking a
combined work, a  derivative of the original library.  The  ordinary
General Public License  therefore permits such linking only if the
entire combination fits  its criteria of freedom.  The Lesser  General
Public License permits  more lax criteria for linking other code with
the library.
  We call this license the "Lesser"  General Public License because it
does Less to protect the  user's freedom than the ordinary General
Public License.  It also provides other free software  developers Less
of an advantage over competing  non-free programs.  These disadvantages
are the reason we use the  ordinary General Public License for many
libraries.  However, the Lesser license provides  advantages in certain
special circumstances.
  For example, on rare occasions, there may be  a special need to
encourage the widest  possible use of a certain library, so that it becomes
a de-facto standard.  To achieve this, non-free programs must be
allowed to use the  library.  A more frequent case is that a  free
library does the same job  as widely used non-free libraries.  In  this
case, there is little to  gain by limiting the free library to free
software only, so we use  the Lesser General Public License.
  In other cases, permission to use a  particular library in non-free
programs enables a greater  number of people to use a large body of
free software.  For example, permission to use the GNU C  Library in
non-free programs enables  many more people to use the whole GNU
operating system, as well  as its variant, the GNU/Linux operating
system.
  Although the Lesser General Public License is  Less protective of the
users' freedom, it does  ensure that the user of a program that is
linked with the Library  has the freedom and the wherewithal to run
that program using a  modified version of the Library.
  The precise terms and conditions for copying,  distribution and
modification follow.  Pay close attention to the difference between  a
"work based on the  library" and a "work that uses the library".  The
former contains code  derived from the library, whereas the latter must
be combined with the  library in order to run.
                  GNU LESSER  GENERAL PUBLIC LICENSE
   TERMS AND CONDITIONS FOR COPYING,  DISTRIBUTION AND MODIFICATION
  0. This License Agreement applies to any  software library or other
program which contains a  notice placed by the copyright holder or
other authorized party  saying it may be distributed under the terms of
this Lesser General Public  License (also called "this License").
Each licensee is addressed  as "you".
  A "library" means a collection of  software functions and/or data
prepared so as to be  conveniently linked with application programs
(which use some of those  functions and data) to form executables.
  The "Library", below, refers to any  such software library or work
which has been distributed  under these terms.  A "work based on  the
Library" means either  the Library or any derivative work under
copyright law: that is to  say, a work containing the Library or a
portion of it, either  verbatim or with modifications and/or translated
straightforwardly into  another language.  (Hereinafter,  translation is
included without  limitation in the term "modification".)
  "Source code" for a work means the  preferred form of the work for
making modifications to  it.  For a library, complete source code  means
all the source code for  all modules it contains, plus any associated
interface definition  files, plus the scripts used to control compilation
and installation of the  library.
  Activities other than copying, distribution  and modification are not
covered by this License;  they are outside its scope.  The act of
running a program using  the Library is not restricted, and output from
such a program is covered  only if its contents constitute a work based
on the Library (independent  of the use of the Library in a tool for
writing it).  Whether that is true depends on what the  Library does
and what the program that  uses the Library does.
  
  1. You may copy and distribute verbatim  copies of the Library's
complete source code as  you receive it, in any medium, provided that
you conspicuously and  appropriately publish on each copy an
appropriate copyright  notice and disclaimer of warranty; keep intact
all the notices that refer  to this License and to the absence of any
warranty; and distribute a  copy of this License along with the
Library.
  You may charge a fee for the physical act of  transferring a copy,
and you may at your option  offer warranty protection in exchange for a
fee.
  2. You may modify your copy or copies of the  Library or any portion
of it, thus forming a work  based on the Library, and copy and
distribute such  modifications or work under the terms of Section 1
above, provided that you  also meet all of these conditions:
a) The modified work must itself be a software library.
    b) You must cause the files modified to  carry prominent notices
    stating that you changed the files and the  date of any change.
    c) You must cause the whole of the work to  be licensed at no
    charge to all third parties under the terms  of this License.
    d) If a facility in the modified Library  refers to a function or a
    table of data to be supplied by an  application program that uses
    the facility, other than as an argument  passed when the facility
    is invoked, then you must make a good faith  effort to ensure that,
    in the event an application does not supply  such function or
    table, the facility still operates, and  performs whatever part of
    its purpose remains meaningful.
    (For example, a function in a library to  compute square roots has
    a purpose that is entirely well-defined  independent of the
    application.  Therefore, Subsection 2d requires that any
    application-supplied function or table used  by this function must
    be optional: if the application does not  supply it, the square
    root function must still compute square  roots.)
These requirements apply  to the modified work as a whole.  If
identifiable sections of  that work are not derived from the Library,
and can be reasonably  considered independent and separate works in
themselves, then this  License, and its terms, do not apply to those
sections when you  distribute them as separate works.  But  when you
distribute the same  sections as part of a whole which is a work based
on the Library, the  distribution of the whole must be on the terms of
this License, whose  permissions for other licensees extend to the
entire whole, and thus to  each and every part regardless of who wrote
it.
Thus, it is not the intent  of this section to claim rights or contest
your rights to work  written entirely by you; rather, the intent is to
exercise the right to  control the distribution of derivative or
collective works based on  the Library.
In addition, mere  aggregation of another work not based on the Library
with the Library (or with  a work based on the Library) on a volume of
a storage or distribution  medium does not bring the other work under
the scope of this License.
  3. You may opt to apply the terms of the  ordinary GNU General Public
License instead of this  License to a given copy of the Library.   To do
this, you must alter all  the notices that refer to this License, so
that they refer to the  ordinary GNU General Public License, version 2,
instead of to this  License.  (If a newer version than  version 2 of the
ordinary GNU General  Public License has appeared, then you can specify
that version instead if  you wish.)  Do not make any other change  in
these notices.
  Once this change is made in a given copy, it  is irreversible for
that copy, so the ordinary  GNU General Public License applies to all
subsequent copies and  derivative works made from that copy.
  This option is useful when you wish to copy  part of the code of
the Library into a program  that is not a library.
  4. You may copy and distribute the Library  (or a portion or
derivative of it, under  Section 2) in object code or executable form
under the terms of  Sections 1 and 2 above provided that you accompany
it with the complete  corresponding machine-readable source code, which
must be distributed under  the terms of Sections 1 and 2 above on a
medium customarily used  for software interchange.
  If distribution of object code is made by  offering access to copy
from a designated place,  then offering equivalent access to copy the
source code from the same  place satisfies the requirement to
distribute the source  code, even though third parties are not
compelled to copy the  source along with the object code.
  5. A program that contains no derivative of  any portion of the
Library, but is designed  to work with the Library by being compiled or
linked with it, is called  a "work that uses the Library".   Such a
work, in isolation, is not  a derivative work of the Library, and
therefore falls outside  the scope of this License.
  However, linking a "work that uses the  Library" with the Library
creates an executable that  is a derivative of the Library (because it
contains portions of the  Library), rather than a "work that uses the
library".  The executable is therefore covered by this  License.
Section 6 states terms for  distribution of such executables.
  When a "work that uses the Library"  uses material from a header file
that is part of the Library,  the object code for the work may be a
derivative work of the  Library even though the source code is not.
Whether this is true is  especially significant if the work can be
linked without the  Library, or if the work is itself a library.   The
threshold for this to be  true is not precisely defined by law.
  If such an object file uses only numerical  parameters, data
structure layouts and  accessors, and small macros and small inline
functions (ten lines or  less in length), then the use of the object
file is unrestricted,  regardless of whether it is legally a derivative
work.  (Executables containing this object code plus  portions of the
Library will still fall  under Section 6.)
  Otherwise, if the work is a derivative of the  Library, you may
distribute the object code  for the work under the terms of Section 6.
Any executables containing  that work also fall under Section 6,
whether or not they are  linked directly with the Library itself.
  6. As an exception to the Sections above, you  may also combine or
link a "work that  uses the Library" with the Library to produce a
work containing portions  of the Library, and distribute that work
under terms of your  choice, provided that the terms permit
modification of the work  for the customer's own use and reverse
engineering for debugging  such modifications.
  You must give prominent notice with each copy  of the work that the
Library is used in it and  that the Library and its use are covered by
this License.  You must supply a copy of this License.  If the work
during execution displays  copyright notices, you must include the
copyright notice for the  Library among them, as well as a reference
directing the user to the  copy of this License.  Also, you must do  one
of these things:
    a) Accompany the work with the complete  corresponding
    machine-readable source code for the  Library including whatever
    changes were used in the work (which must  be distributed under
    Sections 1 and 2 above); and, if the work  is an executable linked
    with the Library, with the complete  machine-readable "work that
    uses the Library", as object code  and/or source code, so that the
    user can modify the Library and then relink  to produce a modified
    executable containing the modified  Library.  (It is understood
    that the user who changes the contents of  definitions files in the
    Library will not necessarily be able to  recompile the application
    to use the modified definitions.)
    b) Use a suitable shared library mechanism  for linking with the
    Library.   A suitable mechanism is one that (1) uses at run time a
    copy of the library already present on the  user's computer system,
    rather than copying library functions into  the executable, and (2)
    will operate properly with a modified  version of the library, if
    the user installs one, as long as the modified  version is
    interface-compatible with the version that  the work was made with.
    c) Accompany the work with a written offer,  valid for at
    least three years, to give the same user  the materials
    specified in Subsection 6a, above, for a charge  no more
    than the cost of performing this  distribution.
    d) If distribution of the work is made by  offering access to copy
    from a designated place, offer equivalent  access to copy the above
    specified materials from the same place.
    e) Verify that the user has already  received a copy of these
    materials or that you have already sent  this user a copy.
  For an executable, the required form of the  "work that uses the
Library" must include  any data and utility programs needed for
reproducing the executable  from it.  However, as a special  exception,
the materials to be  distributed need not include anything that is
normally distributed (in  either source or binary form) with the major
components (compiler,  kernel, and so on) of the operating system on
which the executable runs,  unless that component itself accompanies
the executable.
  It may happen that this requirement  contradicts the license
restrictions of other  proprietary libraries that do not normally
accompany the operating  system.  Such a contradiction means you  cannot
use both them and the  Library together in an executable that you
distribute.
  7. You may place library facilities that are  a work based on the
Library side-by-side in a  single library together with other library
facilities not covered by  this License, and distribute such a combined
library, provided that the  separate distribution of the work based on
the Library and of the  other library facilities is otherwise
permitted, and provided  that you do these two things:
    a) Accompany the combined library with a  copy of the same work
    based on the Library, uncombined with any  other library
    facilities.   This must be distributed under the terms of the
    Sections above.
    b) Give prominent notice with the combined  library of the fact
    that part of it is a work based on the  Library, and explaining
    where to find the accompanying uncombined  form of the same work.
  8. You may not copy, modify, sublicense, link  with, or distribute
the Library except as  expressly provided under this License.   Any
attempt otherwise to copy,  modify, sublicense, link with, or
distribute the Library is  void, and will automatically terminate your
rights under this  License.  However, parties who have  received copies,
or rights, from you under  this License will not have their licenses
terminated so long as such  parties remain in full compliance.
  9. You are not required to accept this  License, since you have not
signed it.  However, nothing else grants you permission  to modify or
distribute the Library or  its derivative works.  These actions are
prohibited by law if you  do not accept this License.  Therefore,  by
modifying or distributing  the Library (or any work based on the
Library), you indicate  your acceptance of this License to do so, and
all its terms and  conditions for copying, distributing or modifying
the Library or works based  on it.
  10. Each time you redistribute the Library  (or any work based on the
Library), the recipient  automatically receives a license from the
original licensor to copy,  distribute, link with or modify the Library
subject to these terms and  conditions.  You may not impose any  further
restrictions on the  recipients' exercise of the rights granted herein.
You are not responsible  for enforcing compliance by third parties with
this License.
  11. If, as a consequence of a court judgment  or allegation of patent
infringement or for any  other reason (not limited to patent issues),
conditions are imposed on  you (whether by court order, agreement or
otherwise) that contradict  the conditions of this License, they do not
excuse you from the  conditions of this License.  If you  cannot
distribute so as to  satisfy simultaneously your obligations under this
License and any other  pertinent obligations, then as a consequence you
may not distribute the  Library at all.  For example, if a patent
license would not permit  royalty-free redistribution of the Library by
all those who receive  copies directly or indirectly through you, then
the only way you could  satisfy both it and this License would be to
refrain entirely from  distribution of the Library.
If any portion of this  section is held invalid or unenforceable under any
particular circumstance,  the balance of the section is intended to apply,
and the section as a whole  is intended to apply in other circumstances.
It is not the purpose of  this section to induce you to infringe any
patents or other property  right claims or to contest validity of any
such claims; this section  has the sole purpose of protecting the
integrity of the free  software distribution system which is
implemented by public  license practices.  Many people have made
generous contributions to  the wide range of software distributed
through that system in  reliance on consistent application of that
system; it is up to the  author/donor to decide if he or she is willing
to distribute software  through any other system and a licensee cannot
impose that choice.
This section is intended  to make thoroughly clear what is believed to
be a consequence of the  rest of this License.
  12. If the distribution and/or use of the  Library is restricted in
certain countries either  by patents or by copyrighted interfaces, the
original copyright holder  who places the Library under this License may add
an explicit geographical  distribution limitation excluding those countries,
so that distribution is  permitted only in or among countries not thus
excluded.  In such case, this License incorporates the  limitation as if
written in the body of  this License.
  13. The Free Software Foundation may publish  revised and/or new
versions of the Lesser  General Public License from time to time.
Such new versions will be  similar in spirit to the present version,
but may differ in detail  to address new problems or concerns.
Each version is given a  distinguishing version number.  If the  Library
specifies a version number  of this License which applies to it and
"any later  version", you have the option of following the terms and
conditions either of that version  or of any later version published by
the Free Software  Foundation.  If the Library does not  specify a
license version number,  you may choose any version ever published by
the Free Software  Foundation.
  14. If you wish to incorporate parts of the Library  into other free
programs whose  distribution conditions are incompatible with these,
write to the author to ask  for permission.  For software which is
copyrighted by the Free  Software Foundation, write to the Free
Software Foundation; we sometimes  make exceptions for this.  Our
decision will be guided by  the two goals of preserving the free status
of all derivatives of our  free software and of promoting the sharing
and reuse of software  generally.
NO WARRANTY
  15. BECAUSE THE LIBRARY IS LICENSED FREE OF  CHARGE, THERE IS NO
WARRANTY FOR THE LIBRARY,  TO THE EXTENT PERMITTED BY APPLICABLE LAW.
EXCEPT WHEN OTHERWISE  STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
OTHER PARTIES PROVIDE THE  LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
KIND, EITHER EXPRESSED OR  IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
IMPLIED WARRANTIES OF  MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND  PERFORMANCE OF THE
LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU  ASSUME
THE COST OF ALL NECESSARY  SERVICING, REPAIR OR CORRECTION.
  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE  LAW OR AGREED TO IN
WRITING WILL ANY COPYRIGHT  HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
AND/OR REDISTRIBUTE THE  LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
FOR DAMAGES, INCLUDING ANY  GENERAL, SPECIAL, INCIDENTAL OR
CONSEQUENTIAL DAMAGES  ARISING OUT OF THE USE OR INABILITY TO USE THE
LIBRARY (INCLUDING BUT NOT  LIMITED TO LOSS OF DATA OR DATA BEING
RENDERED INACCURATE OR  LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
FAILURE OF THE LIBRARY TO  OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
SUCH HOLDER OR OTHER PARTY  HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
DAMAGES.
                     END OF  TERMS AND CONDITIONS
           How to Apply These Terms to Your New  Libraries
  If you develop a new library, and you want it  to be of the greatest
possible use to the  public, we recommend making it free software that
everyone can redistribute  and change.  You can do so by permitting
redistribution under these  terms (or, alternatively, under the terms of the
ordinary General Public  License).
  To apply these terms, attach the following  notices to the library.  It is
safest to attach them to  the start of each source file to most effectively
convey the exclusion of  warranty; and each file should have at least the
"copyright" line  and a pointer to where the full notice is found.
    <one line to give the library's name and  a brief idea of what it does.>
    Copyright (C) <year>  <name of author>
    This library is free software; you can  redistribute it and/or
    modify it under the terms of the GNU Lesser  General Public
    License as published by the Free Software  Foundation; either
    version 2.1 of the License, or (at your  option) any later version.
    This library is distributed in the hope  that it will be useful,
    but WITHOUT ANY WARRANTY; without even the  implied warranty of
    MERCHANTABILITY or FITNESS FOR A PARTICULAR  PURPOSE.  See the GNU
    Lesser General Public License for more  details.
    You should have received a copy of the GNU  Lesser General Public
    License along with this library; if not,  write to the Free Software
    Foundation, Inc., 51 Franklin Street, Fifth  Floor, Boston, MA  02110-1301  USA
Also add information on how to contact you by electronic and paper mail.
You should also get your  employer (if you work as a programmer) or your
school, if any, to sign a  "copyright disclaimer" for the library, if
necessary.  Here is a sample; alter the names:
  Yoyodyne, Inc., hereby disclaims all  copyright interest in the
  library `Frob' (a library for tweaking knobs)  written by James Random Hacker.

That's all there is to it!
