-		    GNU GENERAL PUBLIC LICENSE
-		       Version 2, June 1991
-
- Copyright (C) 1989, 1991 Free Software Foundation, Inc.
-                          675 Mass Ave, Cambridge, MA 02139, 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
-
-	Appendix: 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) 19yy  <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., 675 Mass Ave, Cambridge, MA 02139, 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) 19yy 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.

-GNU LESSER GENERAL PUBLIC LICENSE
-
-Version 2.1, February 1999
-
-Copyright (C) 1991, 1999 Free Software Foundation, Inc.
-59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
-Everyone is permitted to copy and distribute verbatim copies
-of this license document, but changing it is not allowed.
-[This is the first released version of the Lesser GPL. It also counts
-as the successor of the GNU Library Public License, version 2, hence
-the version number 2.1.]
-
-Preamble
-
-The licenses for most software are designed to take away your freedom
-to share and change it. By contrast, the GNU General Public Licenses
-are intended to guarantee your freedom to share and change free
-software--to make sure the software is free for all its users.
-
-This license, the Lesser General Public License, applies to some
-specially designated software packages--typically libraries--of the
-Free Software Foundation and other authors who decide to use it. You
-can use it too, but we suggest you first think carefully about whether
-this license or the ordinary General Public License is the better
-strategy to use in any particular case, based on the explanations
-below.
-
-When we speak of free software, we are referring to freedom of use,
-not price. Our General Public Licenses are designed to make sure that
-you have the freedom to distribute copies of free software (and charge
-for this service if you wish); that you receive source code or can get
-it if you want it; that you can change the software and use pieces of
-it in new free programs; and that you are informed that you can do
-these things.
-
-To protect your rights, we need to make restrictions that forbid
-distributors to deny you these rights or to ask you to surrender these
-rights. These restrictions translate to certain responsibilities for
-you if you distribute copies of the library or if you modify it.
-
-For example, if you distribute copies of the library, whether gratis
-or for a fee, you must give the recipients all the rights that we gave
-you. You must make sure that they, too, receive or can get the source
-code. If you link other code with the library, you must provide
-complete object files to the recipients, so that they can relink them
-with the library after making changes to the library and recompiling
-it. And you must show them these terms so they know their rights.
-
-We protect your rights with a two-step method: (1) we copyright the
-library, and (2) we offer you this license, which gives you legal
-permission to copy, distribute and/or modify the library.
-
-To protect each distributor, we want to make it very clear that there
-is no warranty for the free library. Also, if the library is modified
-by someone else and passed on, the recipients should know that what
-they have is not the original version, so that the original author's
-reputation will not be affected by problems that might be introduced
-by others.
-
-Finally, software patents pose a constant threat to the existence of
-any free program. We wish to make sure that a company cannot
-effectively restrict the users of a free program by obtaining a
-restrictive license from a patent holder. Therefore, we insist that
-any patent license obtained for a version of the library must be
-consistent with the full freedom of use specified in this license.
-
-Most GNU software, including some libraries, is covered by the
-ordinary GNU General Public License. This license, the GNU Lesser
-General Public License, applies to certain designated libraries, and
-is quite different from the ordinary General Public License. We use
-this license for certain libraries in order to permit linking those
-libraries into non-free programs.
-
-When a program is linked with a library, whether statically or using a
-shared library, the combination of the two is legally speaking a
-combined work, a derivative of the original library. The ordinary
-General Public License therefore permits such linking only if the
-entire combination fits its criteria of freedom. The Lesser General
-Public License permits more lax criteria for linking other code with
-the library.
-
-We call this license the"Lesser" General Public License because it
-does Less to protect the user's freedom than the ordinary General
-Public License. It also provides other free software developers Less
-of an advantage over competing non-free programs. These disadvantages
-are the reason we use the ordinary General Public License for many
-libraries. However, the Lesser license provides advantages in certain
-special circumstances.
-
-For example, on rare occasions, there may be a special need to
-encourage the widest possible use of a certain library, so that it
-becomes a de-facto standard. To achieve this, non-free programs must
-be allowed to use the library. A more frequent case is that a free
-library does the same job as widely used non-free libraries. In this
-case, there is little to gain by limiting the free library to free
-software only, so we use the Lesser General Public License.
-
-In other cases, permission to use a particular library in non-free
-programs enables a greater number of people to use a large body of
-free software. For example, permission to use the GNU C Library in
-non-free programs enables many more people to use the whole GNU
-operating system, as well as its variant, the GNU/Linux operating
-system.
-
-Although the Lesser General Public License is Less protective of the
-users' freedom, it does ensure that the user of a program that is
-linked with the Library has the freedom and the wherewithal to run
-that program using a modified version of the Library.
-
-The precise terms and conditions for copying, distribution and
-modification follow. Pay close attention to the difference between a
-"work based on the library" and a"work that uses the library". The
-former contains code derived from the library, whereas the latter must
-be combined with the library in order to run.
-
-TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
-0. This License Agreement applies to any software library or other
-program which contains a notice placed by the copyright holder or
-other authorized party saying it may be distributed under the terms of
-this Lesser General Public License (also called"this License"). Each
-licensee is addressed as"you".
-
-A"library" means a collection of software functions and/or data
-prepared so as to be conveniently linked with application programs
-(which use some of those functions and data) to form executables.
-
-The"Library", below, refers to any such software library or work which
-has been distributed under these terms. A"work based on the Library"
-means either the Library or any derivative work under copyright law:
-that is to say, a work containing the Library or a portion of it,
-either verbatim or with modifications and/or translated
-straightforwardly into another language. (Hereinafter, translation is
-included without limitation in the term"modification".)
-
-"Source code" for a work means the preferred form of the work for
-making modifications to it. For a library, complete source code means
-all the source code for all modules it contains, plus any associated
-interface definition files, plus the scripts used to control
-compilation and installation of the library.
-
-Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope. The act of
-running a program using the Library is not restricted, and output from
-such a program is covered only if its contents constitute a work based
-on the Library (independent of the use of the Library in a tool for
-writing it). Whether that is true depends on what the Library does and
-what the program that uses the Library does.
-
-1. You may copy and distribute verbatim copies of the Library's
-complete source code as you receive it, in any medium, provided that
-you conspicuously and appropriately publish on each copy an
-appropriate copyright notice and disclaimer of warranty; keep intact
-all the notices that refer to this License and to the absence of any
-warranty; and distribute a copy of this License along with the
-Library.
-
-You may charge a fee for the physical act of transferring a copy, and
-you may at your option offer warranty protection in exchange for a
-fee.
-
-2. You may modify your copy or copies of the Library or any portion of
-it, thus forming a work based on the Library, and copy and distribute
-such modifications or work under the terms of Section 1 above,
-provided that you also meet all of these conditions:
-
-• a) The modified work must itself be a software library.
-• b) You must cause the files modified to carry prominent notices
-stating that you changed the files and the date of any change.
-• c) You must cause the whole of the work to be licensed at no charge
-to all third parties under the terms of this License.
-• d) If a facility in the modified Library refers to a function or a
-table of data to be supplied by an application program that uses the
-facility, other than as an argument passed when the facility is
-invoked, then you must make a good faith effort to ensure that, in the
-event an application does not supply such function or table, the
-facility still operates, and performs whatever part of its purpose
-remains meaningful.
-
-(For example, a function in a library to compute square roots has a
-purpose that is entirely well-defined independent of the application.
-Therefore, Subsection 2d requires that any application-supplied
-function or table used by this function must be optional: if the
-application does not supply it, the square root function must still
-compute square roots.)
-
-These requirements apply to the modified work as a whole. If
-identifiable sections of that work are not derived from the Library,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works. But when you
-distribute the same sections as part of a whole which is a work based
-on the Library, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote
-it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Library.
-
-In addition, mere aggregation of another work not based on the Library
-with the Library (or with a work based on the Library) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
-3. You may opt to apply the terms of the ordinary GNU General Public
-License instead of this License to a given copy of the Library. To do
-this, you must alter all the notices that refer to this License, so
-that they refer to the ordinary GNU General Public License, version 2,
-instead of to this License. (If a newer version than version 2 of the
-ordinary GNU General Public License has appeared, then you can specify
-that version instead if you wish.) Do not make any other change in
-these notices.
-
-Once this change is made in a given copy, it is irreversible for that
-copy, so the ordinary GNU General Public License applies to all
-subsequent copies and derivative works made from that copy.
-
-This option is useful when you wish to copy part of the code of the
-Library into a program that is not a library.
-
-4. You may copy and distribute the Library (or a portion or derivative
-of it, under Section 2) in object code or executable form under the
-terms of Sections 1 and 2 above provided that you accompany it with
-the complete corresponding machine-readable source code, which must be
-distributed under the terms of Sections 1 and 2 above on a medium
-customarily used for software interchange.
-
-If distribution of object code is made by offering access to copy from
-a designated place, then offering equivalent access to copy the source
-code from the same place satisfies the requirement to distribute the
-source code, even though third parties are not compelled to copy the
-source along with the object code.
-
-5. A program that contains no derivative of any portion of the
-Library, but is designed to work with the Library by being compiled or
-linked with it, is called a"work that uses the Library". Such a work,
-in isolation, is not a derivative work of the Library, and therefore
-falls outside the scope of this License.
-
-However, linking a"work that uses the Library" with the Library
-creates an executable that is a derivative of the Library (because it
-contains portions of the Library), rather than a"work that uses the
-library". The executable is therefore covered by this License. Section
-6 states terms for distribution of such executables.
-
-When a"work that uses the Library" uses material from a header file
-that is part of the Library, the object code for the work may be a
-derivative work of the Library even though the source code is not.
-Whether this is true is especially significant if the work can be
-linked without the Library, or if the work is itself a library. The
-threshold for this to be true is not precisely defined by law.
-
-If such an object file uses only numerical parameters, data structure
-layouts and accessors, and small macros and small inline functions
-(ten lines or less in length), then the use of the object file is
-unrestricted, regardless of whether it is legally a derivative work.
-(Executables containing this object code plus portions of the Library
-will still fall under Section 6.)
-
-Otherwise, if the work is a derivative of the Library, you may
-distribute the object code for the work under the terms of Section 6.
-Any executables containing that work also fall under Section 6,
-whether or not they are linked directly with the Library itself.
-
-6. As an exception to the Sections above, you may also combine or link
-a"work that uses the Library" with the Library to produce a work
-containing portions of the Library, and distribute that work under
-terms of your choice, provided that the terms permit modification of
-the work for the customer's own use and reverse engineering for
-debugging such modifications.
-
-You must give prominent notice with each copy of the work that the
-Library is used in it and that the Library and its use are covered by
-this License. You must supply a copy of this License. If the work
-during execution displays copyright notices, you must include the
-copyright notice for the Library among them, as well as a reference
-directing the user to the copy of this License. Also, you must do one
-of these things:
-
-• a) Accompany the work with the complete corresponding
-machine-readable source code for the Library including whatever
-changes were used in the work (which must be distributed under
-Sections 1 and 2 above); and, if the work is an executable linked with
-the Library, with the complete machine-readable"work that uses the
-Library", as object code and/or source code, so that the user can
-modify the Library and then relink to produce a modified executable
-containing the modified Library. (It is understood that the user who
-changes the contents of definitions files in the Library will not
-necessarily be able to recompile the application to use the modified
-definitions.)
-• b) Use a suitable shared library mechanism for linking with the
-Library. A suitable mechanism is one that (1) uses at run time a copy
-of the library already present on the user's computer system, rather
-than copying library functions into the executable, and (2) will
-operate properly with a modified version of the library, if the user
-installs one, as long as the modified version is interface-compatible
-with the version that the work was made with.
-• c) Accompany the work with a written offer, valid for at least three
-years, to give the same user the materials specified in Subsection 6a,
-above, for a charge no more than the cost of performing this
-distribution.
-• d) If distribution of the work is made by offering access to copy
-from a designated place, offer equivalent access to copy the above
-specified materials from the same place.
-• e) Verify that the user has already received a copy of these
-materials or that you have already sent this user a copy.
-
-For an executable, the required form of the"work that uses the
-Library" must include any data and utility programs needed for
-reproducing the executable from it. However, as a special exception,
-the materials to be distributed need not include anything that is
-normally distributed (in either source or binary form) with the major
-components (compiler, kernel, and so on) of the operating system on
-which the executable runs, unless that component itself accompanies
-the executable.
-
-It may happen that this requirement contradicts the license
-restrictions of other proprietary libraries that do not normally
-accompany the operating system. Such a contradiction means you cannot
-use both them and the Library together in an executable that you
-distribute.
-
-7. You may place library facilities that are a work based on the
-Library side-by-side in a single library together with other library
-facilities not covered by this License, and distribute such a combined
-library, provided that the separate distribution of the work based on
-the Library and of the other library facilities is otherwise
-permitted, and provided that you do these two things:
-
-• a) Accompany the combined library with a copy of the same work based
-on the Library, uncombined with any other library facilities. This
-must be distributed under the terms of the Sections above.
-• b) Give prominent notice with the combined library of the fact that
-part of it is a work based on the Library, and explaining where to
-find the accompanying uncombined form of the same work.
-
-8. You may not copy, modify, sublicense, link with, or distribute the
-Library except as expressly provided under this License. Any attempt
-otherwise to copy, modify, sublicense, link with, or distribute the
-Library is void, and will automatically terminate your rights under
-this License. However, parties who have received copies, or rights,
-from you under this License will not have their licenses terminated so
-long as such parties remain in full compliance.
-
-9. You are not required to accept this License, since you have not
-signed it. However, nothing else grants you permission to modify or
-distribute the Library or its derivative works. These actions are
-prohibited by law if you do not accept this License. Therefore, by
-modifying or distributing the Library (or any work based on the
-Library), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Library or works based on it.
-
-10. Each time you redistribute the Library (or any work based on the
-Library), the recipient automatically receives a license from the
-original licensor to copy, distribute, link with or modify the Library
-subject to these terms and conditions. You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties with
-this License.
-
-11. If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License. If you cannot
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Library at all. For example, if a patent
-license would not permit royalty-free redistribution of the Library by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Library.
-
-If any portion of this section is held invalid or unenforceable under
-any particular circumstance, the balance of the section is intended to
-apply, and the section as a whole is intended to apply in other
-circumstances.
-
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system which is
-implemented by public license practices. Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-
-12. If the distribution and/or use of the Library is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Library under this License
-may add an explicit geographical distribution limitation excluding
-those countries, so that distribution is permitted only in or among
-countries not thus excluded. In such case, this License incorporates
-the limitation as if written in the body of this License.
-
-13. The Free Software Foundation may publish revised and/or new
-versions of the Lesser General Public License from time to time. Such
-new versions will be similar in spirit to the present version, but may
-differ in detail to address new problems or concerns.
-
-Each version is given a distinguishing version number. If the Library
-specifies a version number of this License which applies to it and"any
-later version", you have the option of following the terms and
-conditions either of that version or of any later version published by
-the Free Software Foundation. If the Library does not specify a
-license version number, you may choose any version ever published by
-the Free Software Foundation.
-
-14. If you wish to incorporate parts of the Library into other free
-programs whose distribution conditions are incompatible with these,
-write to the author to ask for permission. For software which is
-copyrighted by the Free Software Foundation, write to the Free
-Software Foundation; we sometimes make exceptions for this. Our
-decision will be guided by the two goals of preserving the free status
-of all derivatives of our free software and of promoting the sharing
-and reuse of software generally.
-
-NO WARRANTY
-
-15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
-WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
-EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
-OTHER PARTIES PROVIDE THE LIBRARY"AS IS" WITHOUT WARRANTY OF ANY KIND,
-EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
-IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
-PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
-LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
-THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
-
-16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
-WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
-AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
-FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
-CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
-LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
-RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
-FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
-SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
-DAMAGES.

-Lucent Public License Version 1.02
-
-THE ACCOMPANYING PROGRAM IS PROVIDED UNDER THE TERMS OF THIS PUBLIC
-LICENSE ("AGREEMENT"). ANY USE, REPRODUCTION OR DISTRIBUTION OF THE
-PROGRAM CONSTITUTES RECIPIENT'S ACCEPTANCE OF THIS AGREEMENT.
-
-1. DEFINITIONS
-
-"Contribution" means:
-
-  a. in the case of Lucent Technologies Inc. ("LUCENT"), the Original
-     Program, and
-  b. in the case of each Contributor,
-
-     i. changes to the Program, and
-    ii. additions to the Program;
-
-    where such changes and/or additions to the Program were added to the
-    Program by such Contributor itself or anyone acting on such
-    Contributor's behalf, and the Contributor explicitly consents, in
-    accordance with Section 3C, to characterization of the changes and/or
-    additions as Contributions.
-
-"Contributor" means LUCENT and any other entity that has Contributed a
-Contribution to the Program.
-
-"Distributor" means a Recipient that distributes the Program,
-modifications to the Program, or any part thereof.
-
-"Licensed Patents" mean patent claims licensable by a Contributor
-which are necessarily infringed by the use or sale of its Contribution
-alone or when combined with the Program.
-
-"Original Program" means the original version of the software
-accompanying this Agreement as released by LUCENT, including source
-code, object code and documentation, if any.
-
-"Program" means the Original Program and Contributions or any part
-thereof
-
-"Recipient" means anyone who receives the Program under this
-Agreement, including all Contributors.
-
-2. GRANT OF RIGHTS
-
- a. Subject to the terms of this Agreement, each Contributor hereby
-    grants Recipient a non-exclusive, worldwide, royalty-free copyright
-    license to reproduce, prepare derivative works of, publicly display,
-    publicly perform, distribute and sublicense the Contribution of such
-    Contributor, if any, and such derivative works, in source code and
-    object code form.
-    
- b. Subject to the terms of this Agreement, each Contributor hereby
-    grants Recipient a non-exclusive, worldwide, royalty-free patent
-    license under Licensed Patents to make, use, sell, offer to sell,
-    import and otherwise transfer the Contribution of such Contributor, if
-    any, in source code and object code form. The patent license granted
-    by a Contributor shall also apply to the combination of the
-    Contribution of that Contributor and the Program if, at the time the
-    Contribution is added by the Contributor, such addition of the
-    Contribution causes such combination to be covered by the Licensed
-    Patents. The patent license granted by a Contributor shall not apply
-    to (i) any other combinations which include the Contribution, nor to
-    (ii) Contributions of other Contributors. No hardware per se is
-    licensed hereunder.
-    
- c. Recipient understands that although each Contributor grants the
-    licenses to its Contributions set forth herein, no assurances are
-    provided by any Contributor that the Program does not infringe the
-    patent or other intellectual property rights of any other entity. Each
-    Contributor disclaims any liability to Recipient for claims brought by
-    any other entity based on infringement of intellectual property rights
-    or otherwise. As a condition to exercising the rights and licenses
-    granted hereunder, each Recipient hereby assumes sole responsibility
-    to secure any other intellectual property rights needed, if any. For
-    example, if a third party patent license is required to allow
-    Recipient to distribute the Program, it is Recipient's responsibility
-    to acquire that license before distributing the Program.
-
- d. Each Contributor represents that to its knowledge it has sufficient
-    copyright rights in its Contribution, if any, to grant the copyright
-    license set forth in this Agreement.
-
-3. REQUIREMENTS
-
-A. Distributor may choose to distribute the Program in any form under
-this Agreement or under its own license agreement, provided that:
-
- a. it complies with the terms and conditions of this Agreement;
-
- b. if the Program is distributed in source code or other tangible
-    form, a copy of this Agreement or Distributor's own license agreement
-    is included with each copy of the Program; and
-
- c. if distributed under Distributor's own license agreement, such
-    license agreement:
-
-      i. effectively disclaims on behalf of all Contributors all warranties
-         and conditions, express and implied, including warranties or
-         conditions of title and non-infringement, and implied warranties or
-         conditions of merchantability and fitness for a particular purpose;
-     ii. effectively excludes on behalf of all Contributors all liability
-         for damages, including direct, indirect, special, incidental and
-         consequential damages, such as lost profits; and
-    iii. states that any provisions which differ from this Agreement are
-         offered by that Contributor alone and not by any other party.
-
-B. Each Distributor must include the following in a conspicuous
-   location in the Program:
-
-   Copyright (C) 2003, Lucent Technologies Inc. and others. All Rights
-   Reserved.
-
-C. In addition, each Contributor must identify itself as the
-originator of its Contribution in a manner that reasonably allows
-subsequent Recipients to identify the originator of the Contribution.
-Also, each Contributor must agree that the additions and/or changes
-are intended to be a Contribution. Once a Contribution is contributed,
-it may not thereafter be revoked.
-
-4. COMMERCIAL DISTRIBUTION
-
-Commercial distributors of software may accept certain
-responsibilities with respect to end users, business partners and the
-like. While this license is intended to facilitate the commercial use
-of the Program, the Distributor who includes the Program in a
-commercial product offering should do so in a manner which does not
-create potential liability for Contributors. Therefore, if a
-Distributor includes the Program in a commercial product offering,
-such Distributor ("Commercial Distributor") hereby agrees to defend
-and indemnify every Contributor ("Indemnified Contributor") against
-any losses, damages and costs (collectively"Losses") arising from
-claims, lawsuits and other legal actions brought by a third party
-against the Indemnified Contributor to the extent caused by the acts
-or omissions of such Commercial Distributor in connection with its
-distribution of the Program in a commercial product offering. The
-obligations in this section do not apply to any claims or Losses
-relating to any actual or alleged intellectual property infringement.
-In order to qualify, an Indemnified Contributor must: a) promptly
-notify the Commercial Distributor in writing of such claim, and b)
-allow the Commercial Distributor to control, and cooperate with the
-Commercial Distributor in, the defense and any related settlement
-negotiations. The Indemnified Contributor may participate in any such
-claim at its own expense.
-
-For example, a Distributor might include the Program in a commercial
-product offering, Product X. That Distributor is then a Commercial
-Distributor. If that Commercial Distributor then makes performance
-claims, or offers warranties related to Product X, those performance
-claims and warranties are such Commercial Distributor's responsibility
-alone. Under this section, the Commercial Distributor would have to
-defend claims against the Contributors related to those performance
-claims and warranties, and if a court requires any Contributor to pay
-any damages as a result, the Commercial Distributor must pay those
-damages.
-
-5. NO WARRANTY
-
-EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, THE PROGRAM IS
-PROVIDED ON AN"AS IS" BASIS, WITHOUT WARRANTIES OR CONDITIONS OF ANY
-KIND, EITHER EXPRESS OR IMPLIED INCLUDING, WITHOUT LIMITATION, ANY
-WARRANTIES OR CONDITIONS OF TITLE, NON-INFRINGEMENT, MERCHANTABILITY
-OR FITNESS FOR A PARTICULAR PURPOSE. Each Recipient is solely
-responsible for determining the appropriateness of using and
-distributing the Program and assumes all risks associated with its
-exercise of rights under this Agreement, including but not limited to
-the risks and costs of program errors, compliance with applicable
-laws, damage to or loss of data, programs or equipment, and
-unavailability or interruption of operations.
-
-6. DISCLAIMER OF LIABILITY
-
-EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, NEITHER RECIPIENT NOR
-ANY CONTRIBUTORS SHALL HAVE ANY LIABILITY FOR ANY DIRECT, INDIRECT,
-INCIDENTAL, SPECIAL, EXEMPLARY, OR CONSEQUENTIAL DAMAGES (INCLUDING
-WITHOUT LIMITATION LOST PROFITS), HOWEVER CAUSED AND ON ANY THEORY OF
-LIABILITY, WHETHER IN CONTRACT, STRICT LIABILITY, OR TORT (INCLUDING
-NEGLIGENCE OR OTHERWISE) ARISING IN ANY WAY OUT OF THE USE OR
-DISTRIBUTION OF THE PROGRAM OR THE EXERCISE OF ANY RIGHTS GRANTED
-HEREUNDER, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
-
-7. EXPORT CONTROL
-
-Recipient agrees that Recipient alone is responsible for compliance
-with the United States export administration regulations (and the
-export control laws and regulation of any other countries).
-
-8. GENERAL
-
-If any provision of this Agreement is invalid or unenforceable under
-applicable law, it shall not affect the validity or enforceability of
-the remainder of the terms of this Agreement, and without further
-action by the parties hereto, such provision shall be reformed to the
-minimum extent necessary to make such provision valid and enforceable.
-
-If Recipient institutes patent litigation against a Contributor with
-respect to a patent applicable to software (including a cross-claim or
-counterclaim in a lawsuit), then any patent licenses granted by that
-Contributor to such Recipient under this Agreement shall terminate as
-of the date such litigation is filed. In addition, if Recipient
-institutes patent litigation against any entity (including a
-cross-claim or counterclaim in a lawsuit) alleging that the Program
-itself (excluding combinations of the Program with other software or
-hardware) infringes such Recipient's patent(s), then such Recipient's
-rights granted under Section 2(b) shall terminate as of the date such
-litigation is filed.
-
-All Recipient's rights under this Agreement shall terminate if it
-fails to comply with any of the material terms or conditions of this
-Agreement and does not cure such failure in a reasonable period of
-time after becoming aware of such noncompliance. If all Recipient's
-rights under this Agreement terminate, Recipient agrees to cease use
-and distribution of the Program as soon as reasonably practicable.
-However, Recipient's obligations under this Agreement and any licenses
-granted by Recipient relating to the Program shall continue and
-survive.
-
-LUCENT may publish new versions (including revisions) of this
-Agreement from time to time. Each new version of the Agreement will be
-given a distinguishing version number. The Program (including
-Contributions) may always be distributed subject to the version of the
-Agreement under which it was received. In addition, after a new
-version of the Agreement is published, Contributor may elect to
-distribute the Program (including its Contributions) under the new
-version. No one other than LUCENT has the right to modify this
-Agreement. Except as expressly stated in Sections 2(a) and 2(b) above,
-Recipient receives no rights or licenses to the intellectual property
-of any Contributor under this Agreement, whether expressly, by
-implication, estoppel or otherwise. All rights in the Program not
-expressly granted under this Agreement are reserved.
-
-This Agreement is governed by the laws of the State of New York and
-the intellectual property laws of the United States of America. No
-party to this Agreement will bring a legal action under this Agreement
-more than one year after the cause of action arose. Each party waives
-its rights to a jury trial in any resulting litigation.

-Lucent Public License Version 1.02
-
-THE ACCOMPANYING PROGRAM IS PROVIDED UNDER THE TERMS OF THIS PUBLIC
-LICENSE ("AGREEMENT"). ANY USE, REPRODUCTION OR DISTRIBUTION OF THE
-PROGRAM CONSTITUTES RECIPIENT'S ACCEPTANCE OF THIS AGREEMENT.
-
-1. DEFINITIONS
-
-"Contribution" means:
-
-  a. in the case of Lucent Technologies Inc. ("LUCENT"), the Original
-     Program, and
-  b. in the case of each Contributor,
-
-     i. changes to the Program, and
-    ii. additions to the Program;
-
-    where such changes and/or additions to the Program were added to the
-    Program by such Contributor itself or anyone acting on such
-    Contributor's behalf, and the Contributor explicitly consents, in
-    accordance with Section 3C, to characterization of the changes and/or
-    additions as Contributions.
-
-"Contributor" means LUCENT and any other entity that has Contributed a
-Contribution to the Program.
-
-"Distributor" means a Recipient that distributes the Program,
-modifications to the Program, or any part thereof.
-
-"Licensed Patents" mean patent claims licensable by a Contributor
-which are necessarily infringed by the use or sale of its Contribution
-alone or when combined with the Program.
-
-"Original Program" means the original version of the software
-accompanying this Agreement as released by LUCENT, including source
-code, object code and documentation, if any.
-
-"Program" means the Original Program and Contributions or any part
-thereof
-
-"Recipient" means anyone who receives the Program under this
-Agreement, including all Contributors.
-
-2. GRANT OF RIGHTS
-
- a. Subject to the terms of this Agreement, each Contributor hereby
-    grants Recipient a non-exclusive, worldwide, royalty-free copyright
-    license to reproduce, prepare derivative works of, publicly display,
-    publicly perform, distribute and sublicense the Contribution of such
-    Contributor, if any, and such derivative works, in source code and
-    object code form.
-    
- b. Subject to the terms of this Agreement, each Contributor hereby
-    grants Recipient a non-exclusive, worldwide, royalty-free patent
-    license under Licensed Patents to make, use, sell, offer to sell,
-    import and otherwise transfer the Contribution of such Contributor, if
-    any, in source code and object code form. The patent license granted
-    by a Contributor shall also apply to the combination of the
-    Contribution of that Contributor and the Program if, at the time the
-    Contribution is added by the Contributor, such addition of the
-    Contribution causes such combination to be covered by the Licensed
-    Patents. The patent license granted by a Contributor shall not apply
-    to (i) any other combinations which include the Contribution, nor to
-    (ii) Contributions of other Contributors. No hardware per se is
-    licensed hereunder.
-    
- c. Recipient understands that although each Contributor grants the
-    licenses to its Contributions set forth herein, no assurances are
-    provided by any Contributor that the Program does not infringe the
-    patent or other intellectual property rights of any other entity. Each
-    Contributor disclaims any liability to Recipient for claims brought by
-    any other entity based on infringement of intellectual property rights
-    or otherwise. As a condition to exercising the rights and licenses
-    granted hereunder, each Recipient hereby assumes sole responsibility
-    to secure any other intellectual property rights needed, if any. For
-    example, if a third party patent license is required to allow
-    Recipient to distribute the Program, it is Recipient's responsibility
-    to acquire that license before distributing the Program.
-
- d. Each Contributor represents that to its knowledge it has sufficient
-    copyright rights in its Contribution, if any, to grant the copyright
-    license set forth in this Agreement.
-
-3. REQUIREMENTS
-
-A. Distributor may choose to distribute the Program in any form under
-this Agreement or under its own license agreement, provided that:
-
- a. it complies with the terms and conditions of this Agreement;
-
- b. if the Program is distributed in source code or other tangible
-    form, a copy of this Agreement or Distributor's own license agreement
-    is included with each copy of the Program; and
-
- c. if distributed under Distributor's own license agreement, such
-    license agreement:
-
-      i. effectively disclaims on behalf of all Contributors all warranties
-         and conditions, express and implied, including warranties or
-         conditions of title and non-infringement, and implied warranties or
-         conditions of merchantability and fitness for a particular purpose;
-     ii. effectively excludes on behalf of all Contributors all liability
-         for damages, including direct, indirect, special, incidental and
-         consequential damages, such as lost profits; and
-    iii. states that any provisions which differ from this Agreement are
-         offered by that Contributor alone and not by any other party.
-
-B. Each Distributor must include the following in a conspicuous
-   location in the Program:
-
-   Copyright (C) 2003, Lucent Technologies Inc. and others. All Rights
-   Reserved.
-
-C. In addition, each Contributor must identify itself as the
-originator of its Contribution in a manner that reasonably allows
-subsequent Recipients to identify the originator of the Contribution.
-Also, each Contributor must agree that the additions and/or changes
-are intended to be a Contribution. Once a Contribution is contributed,
-it may not thereafter be revoked.
-
-4. COMMERCIAL DISTRIBUTION
-
-Commercial distributors of software may accept certain
-responsibilities with respect to end users, business partners and the
-like. While this license is intended to facilitate the commercial use
-of the Program, the Distributor who includes the Program in a
-commercial product offering should do so in a manner which does not
-create potential liability for Contributors. Therefore, if a
-Distributor includes the Program in a commercial product offering,
-such Distributor ("Commercial Distributor") hereby agrees to defend
-and indemnify every Contributor ("Indemnified Contributor") against
-any losses, damages and costs (collectively"Losses") arising from
-claims, lawsuits and other legal actions brought by a third party
-against the Indemnified Contributor to the extent caused by the acts
-or omissions of such Commercial Distributor in connection with its
-distribution of the Program in a commercial product offering. The
-obligations in this section do not apply to any claims or Losses
-relating to any actual or alleged intellectual property infringement.
-In order to qualify, an Indemnified Contributor must: a) promptly
-notify the Commercial Distributor in writing of such claim, and b)
-allow the Commercial Distributor to control, and cooperate with the
-Commercial Distributor in, the defense and any related settlement
-negotiations. The Indemnified Contributor may participate in any such
-claim at its own expense.
-
-For example, a Distributor might include the Program in a commercial
-product offering, Product X. That Distributor is then a Commercial
-Distributor. If that Commercial Distributor then makes performance
-claims, or offers warranties related to Product X, those performance
-claims and warranties are such Commercial Distributor's responsibility
-alone. Under this section, the Commercial Distributor would have to
-defend claims against the Contributors related to those performance
-claims and warranties, and if a court requires any Contributor to pay
-any damages as a result, the Commercial Distributor must pay those
-damages.
-
-5. NO WARRANTY
-
-EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, THE PROGRAM IS
-PROVIDED ON AN"AS IS" BASIS, WITHOUT WARRANTIES OR CONDITIONS OF ANY
-KIND, EITHER EXPRESS OR IMPLIED INCLUDING, WITHOUT LIMITATION, ANY
-WARRANTIES OR CONDITIONS OF TITLE, NON-INFRINGEMENT, MERCHANTABILITY
-OR FITNESS FOR A PARTICULAR PURPOSE. Each Recipient is solely
-responsible for determining the appropriateness of using and
-distributing the Program and assumes all risks associated with its
-exercise of rights under this Agreement, including but not limited to
-the risks and costs of program errors, compliance with applicable
-laws, damage to or loss of data, programs or equipment, and
-unavailability or interruption of operations.
-
-6. DISCLAIMER OF LIABILITY
-
-EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, NEITHER RECIPIENT NOR
-ANY CONTRIBUTORS SHALL HAVE ANY LIABILITY FOR ANY DIRECT, INDIRECT,
-INCIDENTAL, SPECIAL, EXEMPLARY, OR CONSEQUENTIAL DAMAGES (INCLUDING
-WITHOUT LIMITATION LOST PROFITS), HOWEVER CAUSED AND ON ANY THEORY OF
-LIABILITY, WHETHER IN CONTRACT, STRICT LIABILITY, OR TORT (INCLUDING
-NEGLIGENCE OR OTHERWISE) ARISING IN ANY WAY OUT OF THE USE OR
-DISTRIBUTION OF THE PROGRAM OR THE EXERCISE OF ANY RIGHTS GRANTED
-HEREUNDER, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
-
-7. EXPORT CONTROL
-
-Recipient agrees that Recipient alone is responsible for compliance
-with the United States export administration regulations (and the
-export control laws and regulation of any other countries).
-
-8. GENERAL
-
-If any provision of this Agreement is invalid or unenforceable under
-applicable law, it shall not affect the validity or enforceability of
-the remainder of the terms of this Agreement, and without further
-action by the parties hereto, such provision shall be reformed to the
-minimum extent necessary to make such provision valid and enforceable.
-
-If Recipient institutes patent litigation against a Contributor with
-respect to a patent applicable to software (including a cross-claim or
-counterclaim in a lawsuit), then any patent licenses granted by that
-Contributor to such Recipient under this Agreement shall terminate as
-of the date such litigation is filed. In addition, if Recipient
-institutes patent litigation against any entity (including a
-cross-claim or counterclaim in a lawsuit) alleging that the Program
-itself (excluding combinations of the Program with other software or
-hardware) infringes such Recipient's patent(s), then such Recipient's
-rights granted under Section 2(b) shall terminate as of the date such
-litigation is filed.
-
-All Recipient's rights under this Agreement shall terminate if it
-fails to comply with any of the material terms or conditions of this
-Agreement and does not cure such failure in a reasonable period of
-time after becoming aware of such noncompliance. If all Recipient's
-rights under this Agreement terminate, Recipient agrees to cease use
-and distribution of the Program as soon as reasonably practicable.
-However, Recipient's obligations under this Agreement and any licenses
-granted by Recipient relating to the Program shall continue and
-survive.
-
-LUCENT may publish new versions (including revisions) of this
-Agreement from time to time. Each new version of the Agreement will be
-given a distinguishing version number. The Program (including
-Contributions) may always be distributed subject to the version of the
-Agreement under which it was received. In addition, after a new
-version of the Agreement is published, Contributor may elect to
-distribute the Program (including its Contributions) under the new
-version. No one other than LUCENT has the right to modify this
-Agreement. Except as expressly stated in Sections 2(a) and 2(b) above,
-Recipient receives no rights or licenses to the intellectual property
-of any Contributor under this Agreement, whether expressly, by
-implication, estoppel or otherwise. All rights in the Program not
-expressly granted under this Agreement are reserved.
-
-This Agreement is governed by the laws of the State of New York and
-the intellectual property laws of the United States of America. No
-party to this Agreement will bring a legal action under this Agreement
-more than one year after the cause of action arose. Each party waives
-its rights to a jury trial in any resulting litigation.

-    grants Recipient a non-exclusive, worldwide, royalty-free copyright
-    license to reproduce, prepare derivative works of, publicly display,
-    publicly perform, distribute and sublicense the Contribution of such

-    by a Contributor shall also apply to the combination of the
-    Contribution of that Contributor and the Program if, at the time the
-    Contribution is added by the Contributor, such addition of the
-    Contribution causes such combination to be covered by the Licensed
-    Patents. The patent license granted by a Contributor shall not apply

-
- d. Each Contributor represents that to its knowledge it has sufficient
-    copyright rights in its Contribution, if any, to grant the copyright

-
-3. REQUIREMENTS
-
-A. Distributor may choose to distribute the Program in any form under
-this Agreement or under its own license agreement, provided that:
-
- a. it complies with the terms and conditions of this Agreement;
-
- b. if the Program is distributed in source code or other tangible
-    form, a copy of this Agreement or Distributor's own license agreement
-    is included with each copy of the Program; and
-
- c. if distributed under Distributor's own license agreement, such
-    license agreement:
-
-      i. effectively disclaims on behalf of all Contributors all warranties
-         and conditions, express and implied, including warranties or
-         conditions of title and non-infringement, and implied warranties or
-         conditions of merchantability and fitness for a particular purpose;
-     ii. effectively excludes on behalf of all Contributors all liability
-         for damages, including direct, indirect, special, incidental and
-         consequential damages, such as lost profits; and
-    iii. states that any provisions which differ from this Agreement are
-         offered by that Contributor alone and not by any other party.
-
-B. Each Distributor must include the following in a conspicuous
-   location in the Program:
-
-   Copyright (C) 2003, Lucent Technologies Inc. and others. All Rights
-   Reserved.
-
-C. In addition, each Contributor must identify itself as the
-originator of its Contribution in a manner that reasonably allows
-subsequent Recipients to identify the originator of the Contribution.
-Also, each Contributor must agree that the additions and/or changes
-are intended to be a Contribution. Once a Contribution is contributed,
-it may not thereafter be revoked.
-
-4. COMMERCIAL DISTRIBUTION
-
-Commercial distributors of software may accept certain
-responsibilities with respect to end users, business partners and the
-like. While this license is intended to facilitate the commercial use
-of the Program, the Distributor who includes the Program in a
-commercial product offering should do so in a manner which does not
-create potential liability for Contributors. Therefore, if a
-Distributor includes the Program in a commercial product offering,
-such Distributor ("Commercial Distributor") hereby agrees to defend
-and indemnify every Contributor ("Indemnified Contributor") against
-any losses, damages and costs (collectively"Losses") arising from
-claims, lawsuits and other legal actions brought by a third party
-against the Indemnified Contributor to the extent caused by the acts
-or omissions of such Commercial Distributor in connection with its
-distribution of the Program in a commercial product offering. The
-obligations in this section do not apply to any claims or Losses
-relating to any actual or alleged intellectual property infringement.
-In order to qualify, an Indemnified Contributor must: a) promptly
-notify the Commercial Distributor in writing of such claim, and b)
-allow the Commercial Distributor to control, and cooperate with the
-Commercial Distributor in, the defense and any related settlement
-negotiations. The Indemnified Contributor may participate in any such
-claim at its own expense.
-
-For example, a Distributor might include the Program in a commercial
-product offering, Product X. That Distributor is then a Commercial
-Distributor. If that Commercial Distributor then makes performance
-claims, or offers warranties related to Product X, those performance
-claims and warranties are such Commercial Distributor's responsibility
-alone. Under this section, the Commercial Distributor would have to
-defend claims against the Contributors related to those performance
-claims and warranties, and if a court requires any Contributor to pay
-any damages as a result, the Commercial Distributor must pay those
-damages.
-
-5. NO WARRANTY
-
-EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, THE PROGRAM IS
-PROVIDED ON AN"AS IS" BASIS, WITHOUT WARRANTIES OR CONDITIONS OF ANY
-KIND, EITHER EXPRESS OR IMPLIED INCLUDING, WITHOUT LIMITATION, ANY
-WARRANTIES OR CONDITIONS OF TITLE, NON-INFRINGEMENT, MERCHANTABILITY
-OR FITNESS FOR A PARTICULAR PURPOSE. Each Recipient is solely
-responsible for determining the appropriateness of using and
-distributing the Program and assumes all risks associated with its
-exercise of rights under this Agreement, including but not limited to
-the risks and costs of program errors, compliance with applicable
-laws, damage to or loss of data, programs or equipment, and
-unavailability or interruption of operations.
-
-6. DISCLAIMER OF LIABILITY
-
-EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, NEITHER RECIPIENT NOR
-ANY CONTRIBUTORS SHALL HAVE ANY LIABILITY FOR ANY DIRECT, INDIRECT,
-INCIDENTAL, SPECIAL, EXEMPLARY, OR CONSEQUENTIAL DAMAGES (INCLUDING
-WITHOUT LIMITATION LOST PROFITS), HOWEVER CAUSED AND ON ANY THEORY OF
-LIABILITY, WHETHER IN CONTRACT, STRICT LIABILITY, OR TORT (INCLUDING
-NEGLIGENCE OR OTHERWISE) ARISING IN ANY WAY OUT OF THE USE OR
-DISTRIBUTION OF THE PROGRAM OR THE EXERCISE OF ANY RIGHTS GRANTED
-HEREUNDER, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
-
-7. EXPORT CONTROL
-
-Recipient agrees that Recipient alone is responsible for compliance
-with the United States export administration regulations (and the
-export control laws and regulation of any other countries).
-
-8. GENERAL
-
-If any provision of this Agreement is invalid or unenforceable under
-applicable law, it shall not affect the validity or enforceability of
-the remainder of the terms of this Agreement, and without further
-action by the parties hereto, such provision shall be reformed to the
-minimum extent necessary to make such provision valid and enforceable.
-
-If Recipient institutes patent litigation against a Contributor with
-respect to a patent applicable to software (including a cross-claim or
-counterclaim in a lawsuit), then any patent licenses granted by that
-Contributor to such Recipient under this Agreement shall terminate as
-of the date such litigation is filed. In addition, if Recipient
-institutes patent litigation against any entity (including a
-cross-claim or counterclaim in a lawsuit) alleging that the Program
-itself (excluding combinations of the Program with other software or
-hardware) infringes such Recipient's patent(s), then such Recipient's
-rights granted under Section 2(b) shall terminate as of the date such
-litigation is filed.
-
-All Recipient's rights under this Agreement shall terminate if it
-fails to comply with any of the material terms or conditions of this
-Agreement and does not cure such failure in a reasonable period of
-time after becoming aware of such noncompliance. If all Recipient's
-rights under this Agreement terminate, Recipient agrees to cease use
-and distribution of the Program as soon as reasonably practicable.
-However, Recipient's obligations under this Agreement and any licenses
-granted by Recipient relating to the Program shall continue and
-survive.
-
-LUCENT may publish new versions (including revisions) of this
-Agreement from time to time. Each new version of the Agreement will be
-given a distinguishing version number. The Program (including
-Contributions) may always be distributed subject to the version of the
-Agreement under which it was received. In addition, after a new
-version of the Agreement is published, Contributor may elect to
-distribute the Program (including its Contributions) under the new
-version. No one other than LUCENT has the right to modify this
-Agreement. Except as expressly stated in Sections 2(a) and 2(b) above,
-Recipient receives no rights or licenses to the intellectual property
-of any Contributor under this Agreement, whether expressly, by
-implication, estoppel or otherwise. All rights in the Program not
-expressly granted under this Agreement are reserved.
-
-This Agreement is governed by the laws of the State of New York and
-the intellectual property laws of the United States of America. No
-party to this Agreement will bring a legal action under this Agreement
-more than one year after the cause of action arose. Each party waives
-its rights to a jury trial in any resulting litigation.

-The PC kernel is currently being updated to bring it up-to-date with
-Plan 9 support (the original Inferno PC kernel was derived from an
