 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.)

 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
 them 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.

 Developers that use the GNU GPL protect your rights with two steps:
 (1) assert copyright on the software, and (2) offer you this License
 giving you legal permission to copy, distribute and/or modify the
 software.

 For the developers' and authors' protection, the GPL clearly explains
 that there is no warranty for this free software. For both users' and
 authors' sake, the GPL requires that modified versions be marked as
 changed, so that their problems will not be attributed erroneously to
 authors of previous versions.

 Some devices are designed to deny users access to install or run
 modified versions of the software inside them, although the vendor can
 do so. This is fundamentally incompatible with the aim of
 protecting users' freedom to modify the software. The systematic
 pattern of such abuse occurs in the area of products for individuals to
 use, which should be covered by the GPL. Therefore, the GPL assures
 that users are permitted to distribute copies of free software and
 receive the source code; and that users are entitled to change the
 software and release their changes.

 Finally, any free program is threatened constantly by software patents.
 States should not allow patents to restrict development and use of
 software on general-purpose computers, but in those that do, we wish to
 avoid the danger that patents applied to a free program could make it
 effectively proprietary. To prevent this, the GPL assures that
 patents cannot be used to make the program proprietary.

 The precise terms and conditions for copying, distribution and
 modification follow.

 GNU GENERAL PUBLIC LICENSE
 Version 2, June 1991

 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.)

 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.

 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.

 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 distribute the Program would be to obtain a
 patent license that allows royalty-free redistribution or to refrain
 entirely from distribution.

 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
 programs 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.
