				|  |  | -      institute patent litigation against any entity (including a

				|  |  | -      or contributory patent infringement, then any patent licenses

				|  |  | -
 | 
	
		
			
				|  |  | -      You may add Your own copyright statement to Your modifications and
 | 
	
		
			
				|  |  | -      may provide additional or different license terms and conditions
 | 
	
		
			
				|  |  | -      for use, reproduction, or distribution of Your modifications, or
 | 
	
		
			
				|  |  | -      for any such Derivative Works as a whole, provided Your use,
 | 
	
		
			
				|  |  | -      reproduction, and distribution of the Work otherwise complies with
 | 
	
		
			
				|  |  | -      the conditions stated in this License.

				|  |  | -      with Licensor regarding such Contributions.

				|  |  | -
 | 
	
		
			
				|  |  | -   6. Trademarks. This License does not grant permission to use the trade
 | 
	
		
			
				|  |  | -      names, trademarks, service marks, or product names of the Licensor,
 | 
	
		
			
				|  |  | -      except as required for reasonable and customary use in describing the

				|  |  | -      origin of the Work and reproducing the content of the NOTICE file.
 | 
	
		
			
				|  |  | -
 | 
	
		
			
				|  |  | -   7. Disclaimer of Warranty. Unless required by applicable law or
 | 
	
		
			
				|  |  | -      agreed to in writing, Licensor provides the Work (and each

				|  |  | -      Contributor provides its Contributions) on an "AS IS" BASIS,

				|  |  | -      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or

 | 
	
		
			
				|  |  | -      whether in tort (including negligence), contract, or otherwise,

				|  |  | -      unless required by applicable law (such as deliberate and grossly
 | 
	
		
			
				|  |  | -      negligent acts) or agreed to in writing, shall any Contributor be
 | 
	
		
			
				|  |  | -      liable to You for damages, including any direct, indirect, special,
 | 
	
		
			
				|  |  | -      incidental, or consequential damages of any character arising as a
 | 
	
		
			
				|  |  | -      result of this License or out of the use or inability to use the

				|  |  | -      work stoppage, computer failure or malfunction, or any and all
 | 
	
		
			
				|  |  | -      other commercial damages or losses), even if such Contributor
 | 
	
		
			
				|  |  | -      has been advised of the possibility of such damages.

				|  |  | -
 |

 | 
	
		
			
				|  |  | -      or other liability obligations and/or rights consistent with this
 | 
	
		
			
				|  |  | -      License. However, in accepting such obligations, You may act only
 | 
	
		
			
				|  |  | -      on Your own behalf and on Your sole responsibility, not on behalf
 | 
	
		
			
				|  |  | -      of any other Contributor, and only if You agree to indemnify,
 | 
	
		
			
				|  |  | -      defend, and hold each Contributor harmless for any liability
 | 
	
		
			
				|  |  | -      incurred by, or claims asserted against, such Contributor by reason
 | 
	
		
			
				|  |  | -      of your accepting any such warranty or additional liability.

 | 
	
		
			
				|  |  | +
 | 
	
		
			
				|  |  | +  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.
