 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.
