     7  Everyone is permitted to copy and distribute verbatim copies
     8  of this license document, but changing it is not allowed.
     9 
    10 			    Preamble
    11 
    12   The licenses for most software are designed to take away your
    13 freedom to share and change it.  By contrast, the GNU General Public
    14 License is intended to guarantee your freedom to share and change free
    15 software--to make sure the software is free for all its users.  This
    16 General Public License applies to most of the Free Software
    17 Foundation's software and to any other program whose authors commit to
    18 using it.  (Some other Free Software Foundation software is covered by
    19 the GNU Library General Public License instead.)  You can apply it to
    20 your programs, too.
    21 
    22   When we speak of free software, we are referring to freedom, not
    23 price.  Our General Public Licenses are designed to make sure that you
    24 have the freedom to distribute copies of free software (and charge for
    25 this service if you wish), that you receive source code or can get it
    26 if you want it, that you can change the software or use pieces of it
    27 in new free programs; and that you know you can do these things.
    28 
    29   To protect your rights, we need to make restrictions that forbid
    30 anyone to deny you these rights or to ask you to surrender the rights.
    31 These restrictions translate to certain responsibilities for you if you
    32 distribute copies of the software, or if you modify it.
    33 
    34   For example, if you distribute copies of such a program, whether
    35 gratis or for a fee, you must give the recipients all the rights that
    36 you have.  You must make sure that they, too, receive or can get the
    37 source code.  And you must show them these terms so they know their
    38 rights.
    39 
    40   We protect your rights with two steps: (1) copyright the software, and
    41 (2) offer you this license which gives you legal permission to copy,
    42 distribute and/or modify the software.
    43 
    44   Also, for each author's protection and ours, we want to make certain
    45 that everyone understands that there is no warranty for this free
    46 software.  If the software is modified by someone else and passed on, we
    47 want its recipients to know that what they have is not the original, so
    48 that any problems introduced by others will not reflect on the original
    49 authors' reputations.
    50 
    51   Finally, any free program is threatened constantly by software
    52 patents.  We wish to avoid the danger that redistributors of a free
    53 program will individually obtain patent licenses, in effect making the
    54 program proprietary.  To prevent this, we have made it clear that any
    55 patent must be licensed for everyone's free use or not licensed at all.
    56 
    57   The precise terms and conditions for copying, distribution and
    58 modification follow.
    59 
    60 		    GNU GENERAL PUBLIC LICENSE
    61    TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
    62 
    63   0. This License applies to any program or other work which contains
    64 a notice placed by the copyright holder saying it may be distributed
    65 under the terms of this General Public License.  The "Program", below,
    66 refers to any such program or work, and a "work based on the Program"
    67 means either the Program or any derivative work under copyright law:
    68 that is to say, a work containing the Program or a portion of it,
    69 either verbatim or with modifications and/or translated into another
    70 language.  (Hereinafter, translation is included without limitation in
    71 the term "modification".)  Each licensee is addressed as "you".
    72 
    73 Activities other than copying, distribution and modification are not
    74 covered by this License; they are outside its scope.  The act of
    75 running the Program is not restricted, and the output from the Program
    76 is covered only if its contents constitute a work based on the
    77 Program (independent of having been made by running the Program).
    78 Whether that is true depends on what the Program does.
    79 
    80   1. You may copy and distribute verbatim copies of the Program's
    81 source code as you receive it, in any medium, provided that you
    82 conspicuously and appropriately publish on each copy an appropriate
    83 copyright notice and disclaimer of warranty; keep intact all the
    84 notices that refer to this License and to the absence of any warranty;
    85 and give any other recipients of the Program a copy of this License
    86 along with the Program.
    87 
    88 You may charge a fee for the physical act of transferring a copy, and
    89 you may at your option offer warranty protection in exchange for a fee.
    90 
    91   2. You may modify your copy or copies of the Program or any portion
    92 of it, thus forming a work based on the Program, and copy and
    93 distribute such modifications or work under the terms of Section 1
    94 above, provided that you also meet all of these conditions:
    95 
    96     a) You must cause the modified files to carry prominent notices
    97     stating that you changed the files and the date of any change.
    98 
    99     b) You must cause any work that you distribute or publish, that in
   100     whole or in part contains or is derived from the Program or any
   101     part thereof, to be licensed as a whole at no charge to all third
   102     parties under the terms of this License.
   103 
   104     c) If the modified program normally reads commands interactively
   105     when run, you must cause it, when started running for such
   106     interactive use in the most ordinary way, to print or display an
   107     announcement including an appropriate copyright notice and a
   108     notice that there is no warranty (or else, saying that you provide
   109     a warranty) and that users may redistribute the program under
   110     these conditions, and telling the user how to view a copy of this
   111     License.  (Exception: if the Program itself is interactive but
   112     does not normally print such an announcement, your work based on
   113     the Program is not required to print an announcement.)
   114 
   115 These requirements apply to the modified work as a whole.  If
   116 identifiable sections of that work are not derived from the Program,
   117 and can be reasonably considered independent and separate works in
   118 themselves, then this License, and its terms, do not apply to those
   119 sections when you distribute them as separate works.  But when you
   120 distribute the same sections as part of a whole which is a work based
   121 on the Program, the distribution of the whole must be on the terms of
   122 this License, whose permissions for other licensees extend to the
   123 entire whole, and thus to each and every part regardless of who wrote it.
   124 
   125 Thus, it is not the intent of this section to claim rights or contest
   126 your rights to work written entirely by you; rather, the intent is to
   127 exercise the right to control the distribution of derivative or
   128 collective works based on the Program.
   129 
   130 In addition, mere aggregation of another work not based on the Program
   131 with the Program (or with a work based on the Program) on a volume of
   132 a storage or distribution medium does not bring the other work under
   133 the scope of this License.
   134 
   135   3. You may copy and distribute the Program (or a work based on it,
   136 under Section 2) in object code or executable form under the terms of
   137 Sections 1 and 2 above provided that you also do one of the following:
   138 
   139     a) Accompany it with the complete corresponding machine-readable
   140     source code, which must be distributed under the terms of Sections
   141     1 and 2 above on a medium customarily used for software interchange; or,
   142 
   143     b) Accompany it with a written offer, valid for at least three
   144     years, to give any third party, for a charge no more than your
   145     cost of physically performing source distribution, a complete
   146     machine-readable copy of the corresponding source code, to be
   147     distributed under the terms of Sections 1 and 2 above on a medium
   148     customarily used for software interchange; or,
   149 
   150     c) Accompany it with the information you received as to the offer
   151     to distribute corresponding source code.  (This alternative is
   152     allowed only for noncommercial distribution and only if you
   153     received the program in object code or executable form with such
   154     an offer, in accord with Subsection b above.)
   155 
   156 The source code for a work means the preferred form of the work for
   157 making modifications to it.  For an executable work, complete source
   158 code means all the source code for all modules it contains, plus any
   159 associated interface definition files, plus the scripts used to
   160 control compilation and installation of the executable.  However, as a
   161 special exception, the source code distributed need not include
   162 anything that is normally distributed (in either source or binary
   163 form) with the major components (compiler, kernel, and so on) of the
   164 operating system on which the executable runs, unless that component
   165 itself accompanies the executable.
   166 
   167 If distribution of executable or object code is made by offering
   168 access to copy from a designated place, then offering equivalent
   169 access to copy the source code from the same place counts as
   170 distribution of the source code, even though third parties are not
   171 compelled to copy the source along with the object code.
   172 
   173   4. You may not copy, modify, sublicense, or distribute the Program
   174 except as expressly provided under this License.  Any attempt
   175 otherwise to copy, modify, sublicense or distribute the Program is
   176 void, and will automatically terminate your rights under this License.
   177 However, parties who have received copies, or rights, from you under
   178 this License will not have their licenses terminated so long as such
   179 parties remain in full compliance.
   180 
   181   5. You are not required to accept this License, since you have not
   182 signed it.  However, nothing else grants you permission to modify or
   183 distribute the Program or its derivative works.  These actions are
   184 prohibited by law if you do not accept this License.  Therefore, by
   185 modifying or distributing the Program (or any work based on the
   186 Program), you indicate your acceptance of this License to do so, and
   187 all its terms and conditions for copying, distributing or modifying
   188 the Program or works based on it.
   189 
   190   6. Each time you redistribute the Program (or any work based on the
   191 Program), the recipient automatically receives a license from the
   192 original licensor to copy, distribute or modify the Program subject to
   193 these terms and conditions.  You may not impose any further
   194 restrictions on the recipients' exercise of the rights granted herein.
   195 You are not responsible for enforcing compliance by third parties to
   196 this License.
   197 
   198   7. If, as a consequence of a court judgment or allegation of patent
   199 infringement or for any other reason (not limited to patent issues),
   200 conditions are imposed on you (whether by court order, agreement or
   201 otherwise) that contradict the conditions of this License, they do not
   202 excuse you from the conditions of this License.  If you cannot
   203 distribute so as to satisfy simultaneously your obligations under this
   204 License and any other pertinent obligations, then as a consequence you
   205 may not distribute the Program at all.  For example, if a patent
   206 license would not permit royalty-free redistribution of the Program by
   207 all those who receive copies directly or indirectly through you, then
   208 the only way you could satisfy both it and this License would be to
   209 refrain entirely from distribution of the Program.
   210 
   211 If any portion of this section is held invalid or unenforceable under
   212 any particular circumstance, the balance of the section is intended to
   213 apply and the section as a whole is intended to apply in other
   214 circumstances.
   215 
   216 It is not the purpose of this section to induce you to infringe any
   217 patents or other property right claims or to contest validity of any
   218 such claims; this section has the sole purpose of protecting the
   219 integrity of the free software distribution system, which is
   220 implemented by public license practices.  Many people have made
   221 generous contributions to the wide range of software distributed
   222 through that system in reliance on consistent application of that
   223 system; it is up to the author/donor to decide if he or she is willing
   224 to distribute software through any other system and a licensee cannot
   225 impose that choice.
   226 
   227 This section is intended to make thoroughly clear what is believed to
   228 be a consequence of the rest of this License.
   229 
   230   8. If the distribution and/or use of the Program is restricted in
   231 certain countries either by patents or by copyrighted interfaces, the
   232 original copyright holder who places the Program under this License
   233 may add an explicit geographical distribution limitation excluding
   234 those countries, so that distribution is permitted only in or among
   235 countries not thus excluded.  In such case, this License incorporates
   236 the limitation as if written in the body of this License.
   237 
   238   9. The Free Software Foundation may publish revised and/or new versions
   239 of the General Public License from time to time.  Such new versions will
   240 be similar in spirit to the present version, but may differ in detail to
   241 address new problems or concerns.
   242 
   243 Each version is given a distinguishing version number.  If the Program
   244 specifies a version number of this License which applies to it and "any
   245 later version", you have the option of following the terms and conditions
   246 either of that version or of any later version published by the Free
   247 Software Foundation.  If the Program does not specify a version number of
   248 this License, you may choose any version ever published by the Free Software
   249 Foundation.
   250 
   251   10. If you wish to incorporate parts of the Program into other free
   252 programs whose distribution conditions are different, write to the author
   253 to ask for permission.  For software which is copyrighted by the Free
   254 Software Foundation, write to the Free Software Foundation; we sometimes
   255 make exceptions for this.  Our decision will be guided by the two goals
   256 of preserving the free status of all derivatives of our free software and
   257 of promoting the sharing and reuse of software generally.
   258 
   259 			    NO WARRANTY
   260 
   261   11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
   262 FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
   263 OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
   264 PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
   265 OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
   266 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
   267 TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
   268 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
   269 REPAIR OR CORRECTION.
   270 
   271   12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
   272 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
   273 REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
   274 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
   275 OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
   276 TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
   277 YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
   278 PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
   279 POSSIBILITY OF SUCH DAMAGES.
   280 
   281 		     END OF TERMS AND CONDITIONS
   282 
   283 	Appendix: How to Apply These Terms to Your New Programs
   284 
   285   If you develop a new program, and you want it to be of the greatest
   286 possible use to the public, the best way to achieve this is to make it
   287 free software which everyone can redistribute and change under these terms.
   288 
   289   To do so, attach the following notices to the program.  It is safest
   290 to attach them to the start of each source file to most effectively
   291 convey the exclusion of warranty; and each file should have at least
   292 the "copyright" line and a pointer to where the full notice is found.
   293 
   294     <one line to give the program's name and a brief idea of what it does.>
   295     Copyright (C) 19yy  <name of author>
   296 
   297     This program is free software; you can redistribute it and/or modify
   298     it under the terms of the GNU General Public License as published by
   299     the Free Software Foundation; either version 2 of the License, or
   300     (at your option) any later version.
   301 
   302     This program is distributed in the hope that it will be useful,
   303     but WITHOUT ANY WARRANTY; without even the implied warranty of
   304     MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
   305     GNU General Public License for more details.
   306 
   307     You should have received a copy of the GNU General Public License
   308     along with this program; if not, write to the Free Software
   309     Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
   310 
   311 Also add information on how to contact you by electronic and paper mail.
   312 
   313 If the program is interactive, make it output a short notice like this
   314 when it starts in an interactive mode:
   315 
   316     Gnomovision version 69, Copyright (C) 19yy name of author
   317     Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
   318     This is free software, and you are welcome to redistribute it
   319     under certain conditions; type `show c' for details.
   320 
   321 The hypothetical commands `show w' and `show c' should show the appropriate
   322 parts of the General Public License.  Of course, the commands you use may
   323 be called something other than `show w' and `show c'; they could even be
   324 mouse-clicks or menu items--whatever suits your program.
   325 
   326 You should also get your employer (if you work as a programmer) or your
   327 school, if any, to sign a "copyright disclaimer" for the program, if
   328 necessary.  Here is a sample; alter the names:
   329 
   330   Yoyodyne, Inc., hereby disclaims all copyright interest in the program
   331   `Gnomovision' (which makes passes at compilers) written by James Hacker.

   335 
   336 This General Public License does not permit incorporating your program into
   337 proprietary programs.  If your program is a subroutine library, you may
   338 consider it more useful to permit linking proprietary applications with the
   339 library.  If this is what you want to do, use the GNU Library General
   340 Public License instead of this License.
