    18  Everyone is permitted to copy and distribute verbatim copies
       
    19  of this license document, but changing it is not allowed.

    21 			    Preamble
       
    22 
       
    23   The licenses for most software are designed to take away your
       
    24 freedom to share and change it.  By contrast, the GNU General Public
       
    25 License is intended to guarantee your freedom to share and change free
       
    26 software--to make sure the software is free for all its users.  This
       
    27 General Public License applies to most of the Free Software
       
    28 Foundation's software and to any other program whose authors commit to
       
    29 using it.  (Some other Free Software Foundation software is covered by
       
    30 the GNU Library General Public License instead.)  You can apply it to
       
    31 your programs, too.
       
    32 
       
    33   When we speak of free software, we are referring to freedom, not
       
    34 price.  Our General Public Licenses are designed to make sure that you
       
    35 have the freedom to distribute copies of free software (and charge for
       
    36 this service if you wish), that you receive source code or can get it
       
    37 if you want it, that you can change the software or use pieces of it
       
    38 in new free programs; and that you know you can do these things.
       
    39 
       
    40   To protect your rights, we need to make restrictions that forbid
       
    41 anyone to deny you these rights or to ask you to surrender the rights.
       
    42 These restrictions translate to certain responsibilities for you if you
       
    43 distribute copies of the software, or if you modify it.
       
    44 
       
    45   For example, if you distribute copies of such a program, whether
       
    46 gratis or for a fee, you must give the recipients all the rights that
       
    47 you have.  You must make sure that they, too, receive or can get the
       
    48 source code.  And you must show them these terms so they know their
       
    49 rights.
       
    50 
       
    51   We protect your rights with two steps: (1) copyright the software, and
       
    52 (2) offer you this license which gives you legal permission to copy,
       
    53 distribute and/or modify the software.
       
    54 
       
    55   Also, for each author's protection and ours, we want to make certain
       
    56 that everyone understands that there is no warranty for this free
       
    57 software.  If the software is modified by someone else and passed on, we
       
    58 want its recipients to know that what they have is not the original, so
       
    59 that any problems introduced by others will not reflect on the original
       
    60 authors' reputations.
       
    61 
       
    62   Finally, any free program is threatened constantly by software
       
    63 patents.  We wish to avoid the danger that redistributors of a free
       
    64 program will individually obtain patent licenses, in effect making the
       
    65 program proprietary.  To prevent this, we have made it clear that any
       
    66 patent must be licensed for everyone's free use or not licensed at all.
       
    67 
       
    68   The precise terms and conditions for copying, distribution and
       
    69 modification follow.

    71 		    GNU GENERAL PUBLIC LICENSE
       
    72    TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
       
    73 
       
    74   0. This License applies to any program or other work which contains
       
    75 a notice placed by the copyright holder saying it may be distributed
       
    76 under the terms of this General Public License.  The "Program", below,
       
    77 refers to any such program or work, and a "work based on the Program"
       
    78 means either the Program or any derivative work under copyright law:
       
    79 that is to say, a work containing the Program or a portion of it,
       
    80 either verbatim or with modifications and/or translated into another
       
    81 language.  (Hereinafter, translation is included without limitation in
       
    82 the term "modification".)  Each licensee is addressed as "you".
       
    83 
       
    84 Activities other than copying, distribution and modification are not
       
    85 covered by this License; they are outside its scope.  The act of
       
    86 running the Program is not restricted, and the output from the Program
       
    87 is covered only if its contents constitute a work based on the
       
    88 Program (independent of having been made by running the Program).
       
    89 Whether that is true depends on what the Program does.
       
    90 
       
    91   1. You may copy and distribute verbatim copies of the Program's
       
    92 source code as you receive it, in any medium, provided that you
       
    93 conspicuously and appropriately publish on each copy an appropriate
       
    94 copyright notice and disclaimer of warranty; keep intact all the
       
    95 notices that refer to this License and to the absence of any warranty;
       
    96 and give any other recipients of the Program a copy of this License
       
    97 along with the Program.
       
    98 
       
    99 You may charge a fee for the physical act of transferring a copy, and
       
   100 you may at your option offer warranty protection in exchange for a fee.
       
   101 
       
   102   2. You may modify your copy or copies of the Program or any portion
       
   103 of it, thus forming a work based on the Program, and copy and
       
   104 distribute such modifications or work under the terms of Section 1
       
   105 above, provided that you also meet all of these conditions:
       
   106 
       
   107     a) You must cause the modified files to carry prominent notices
       
   108     stating that you changed the files and the date of any change.
       
   109 
       
   110     b) You must cause any work that you distribute or publish, that in
       
   111     whole or in part contains or is derived from the Program or any
       
   112     part thereof, to be licensed as a whole at no charge to all third
       
   113     parties under the terms of this License.
       
   114 
       
   115     c) If the modified program normally reads commands interactively
       
   116     when run, you must cause it, when started running for such
       
   117     interactive use in the most ordinary way, to print or display an
       
   118     announcement including an appropriate copyright notice and a
       
   119     notice that there is no warranty (or else, saying that you provide
       
   120     a warranty) and that users may redistribute the program under
       
   121     these conditions, and telling the user how to view a copy of this
       
   122     License.  (Exception: if the Program itself is interactive but
       
   123     does not normally print such an announcement, your work based on
       
   124     the Program is not required to print an announcement.)
       
   125 
       
   126 These requirements apply to the modified work as a whole.  If
       
   127 identifiable sections of that work are not derived from the Program,
       
   128 and can be reasonably considered independent and separate works in
       
   129 themselves, then this License, and its terms, do not apply to those
       
   130 sections when you distribute them as separate works.  But when you
       
   131 distribute the same sections as part of a whole which is a work based
       
   132 on the Program, the distribution of the whole must be on the terms of
       
   133 this License, whose permissions for other licensees extend to the
       
   134 entire whole, and thus to each and every part regardless of who wrote it.
       
   135 
       
   136 Thus, it is not the intent of this section to claim rights or contest
       
   137 your rights to work written entirely by you; rather, the intent is to
       
   138 exercise the right to control the distribution of derivative or
       
   139 collective works based on the Program.
       
   140 
       
   141 In addition, mere aggregation of another work not based on the Program
       
   142 with the Program (or with a work based on the Program) on a volume of
       
   143 a storage or distribution medium does not bring the other work under
       
   144 the scope of this License.
       
   145 
       
   146   3. You may copy and distribute the Program (or a work based on it,
       
   147 under Section 2) in object code or executable form under the terms of
       
   148 Sections 1 and 2 above provided that you also do one of the following:
       
   149 
       
   150     a) Accompany it with the complete corresponding machine-readable
       
   151     source code, which must be distributed under the terms of Sections
       
   152     1 and 2 above on a medium customarily used for software interchange; or,
       
   153 
       
   154     b) Accompany it with a written offer, valid for at least three
       
   155     years, to give any third party, for a charge no more than your
       
   156     cost of physically performing source distribution, a complete
       
   157     machine-readable copy of the corresponding source code, to be
       
   158     distributed under the terms of Sections 1 and 2 above on a medium
       
   159     customarily used for software interchange; or,
       
   160 
       
   161     c) Accompany it with the information you received as to the offer
       
   162     to distribute corresponding source code.  (This alternative is
       
   163     allowed only for noncommercial distribution and only if you
       
   164     received the program in object code or executable form with such
       
   165     an offer, in accord with Subsection b above.)
       
   166 
       
   167 The source code for a work means the preferred form of the work for
       
   168 making modifications to it.  For an executable work, complete source
       
   169 code means all the source code for all modules it contains, plus any
       
   170 associated interface definition files, plus the scripts used to
       
   171 control compilation and installation of the executable.  However, as a
       
   172 special exception, the source code distributed need not include
       
   173 anything that is normally distributed (in either source or binary
       
   174 form) with the major components (compiler, kernel, and so on) of the
       
   175 operating system on which the executable runs, unless that component
       
   176 itself accompanies the executable.
       
   177 
       
   178 If distribution of executable or object code is made by offering
       
   179 access to copy from a designated place, then offering equivalent
       
   180 access to copy the source code from the same place counts as
       
   181 distribution of the source code, even though third parties are not
       
   182 compelled to copy the source along with the object code.
       
   183 
       
   184   4. You may not copy, modify, sublicense, or distribute the Program
       
   185 except as expressly provided under this License.  Any attempt
       
   186 otherwise to copy, modify, sublicense or distribute the Program is
       
   187 void, and will automatically terminate your rights under this License.
       
   188 However, parties who have received copies, or rights, from you under
       
   189 this License will not have their licenses terminated so long as such
       
   190 parties remain in full compliance.
       
   191 
       
   192   5. You are not required to accept this License, since you have not
       
   193 signed it.  However, nothing else grants you permission to modify or
       
   194 distribute the Program or its derivative works.  These actions are
       
   195 prohibited by law if you do not accept this License.  Therefore, by
       
   196 modifying or distributing the Program (or any work based on the
       
   197 Program), you indicate your acceptance of this License to do so, and
       
   198 all its terms and conditions for copying, distributing or modifying
       
   199 the Program or works based on it.
       
   200 
       
   201   6. Each time you redistribute the Program (or any work based on the
       
   202 Program), the recipient automatically receives a license from the
       
   203 original licensor to copy, distribute or modify the Program subject to
       
   204 these terms and conditions.  You may not impose any further
       
   205 restrictions on the recipients' exercise of the rights granted herein.
       
   206 You are not responsible for enforcing compliance by third parties to
       
   207 this License.
       
   208 
       
   209   7. If, as a consequence of a court judgment or allegation of patent
       
   210 infringement or for any other reason (not limited to patent issues),
       
   211 conditions are imposed on you (whether by court order, agreement or
       
   212 otherwise) that contradict the conditions of this License, they do not
       
   213 excuse you from the conditions of this License.  If you cannot
       
   214 distribute so as to satisfy simultaneously your obligations under this
       
   215 License and any other pertinent obligations, then as a consequence you
       
   216 may not distribute the Program at all.  For example, if a patent
       
   217 license would not permit royalty-free redistribution of the Program by
       
   218 all those who receive copies directly or indirectly through you, then
       
   219 the only way you could satisfy both it and this License would be to
       
   220 refrain entirely from distribution of the Program.
       
   221 
       
   222 If any portion of this section is held invalid or unenforceable under
       
   223 any particular circumstance, the balance of the section is intended to
       
   224 apply and the section as a whole is intended to apply in other
       
   225 circumstances.
       
   226 
       
   227 It is not the purpose of this section to induce you to infringe any
       
   228 patents or other property right claims or to contest validity of any
       
   229 such claims; this section has the sole purpose of protecting the
       
   230 integrity of the free software distribution system, which is
       
   231 implemented by public license practices.  Many people have made
       
   232 generous contributions to the wide range of software distributed
       
   233 through that system in reliance on consistent application of that
       
   234 system; it is up to the author/donor to decide if he or she is willing
       
   235 to distribute software through any other system and a licensee cannot
       
   236 impose that choice.
       
   237 
       
   238 This section is intended to make thoroughly clear what is believed to
       
   239 be a consequence of the rest of this License.
       
   240 
       
   241   8. If the distribution and/or use of the Program is restricted in
       
   242 certain countries either by patents or by copyrighted interfaces, the
       
   243 original copyright holder who places the Program under this License
       
   244 may add an explicit geographical distribution limitation excluding
       
   245 those countries, so that distribution is permitted only in or among
       
   246 countries not thus excluded.  In such case, this License incorporates
       
   247 the limitation as if written in the body of this License.
       
   248 
       
   249   9. The Free Software Foundation may publish revised and/or new versions
       
   250 of the General Public License from time to time.  Such new versions will
       
   251 be similar in spirit to the present version, but may differ in detail to
       
   252 address new problems or concerns.
       
   253 
       
   254 Each version is given a distinguishing version number.  If the Program
       
   255 specifies a version number of this License which applies to it and "any
       
   256 later version", you have the option of following the terms and conditions
       
   257 either of that version or of any later version published by the Free
       
   258 Software Foundation.  If the Program does not specify a version number of
       
   259 this License, you may choose any version ever published by the Free Software
       
   260 Foundation.
       
   261 
       
   262   10. If you wish to incorporate parts of the Program into other free
       
   263 programs whose distribution conditions are different, write to the author
       
   264 to ask for permission.  For software which is copyrighted by the Free
       
   265 Software Foundation, write to the Free Software Foundation; we sometimes
       
   266 make exceptions for this.  Our decision will be guided by the two goals
       
   267 of preserving the free status of all derivatives of our free software and
       
   268 of promoting the sharing and reuse of software generally.
       
   269 
       
   270 			    NO WARRANTY
       
   271 
       
   272   11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
       
   273 FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
       
   274 OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
       
   275 PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
       
   276 OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
       
   277 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
       
   278 TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
       
   279 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
       
   280 REPAIR OR CORRECTION.
       
   281 
       
   282   12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
       
   283 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
       
   284 REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
       
   285 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
       
   286 OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
       
   287 TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
       
   288 YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
       
   289 PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
       
   290 POSSIBILITY OF SUCH DAMAGES.

   294 	    How to Apply These Terms to Your New Programs
       
   295 
       
   296   If you develop a new program, and you want it to be of the greatest
       
   297 possible use to the public, the best way to achieve this is to make it
       
   298 free software which everyone can redistribute and change under these terms.
       
   299 
       
   300   To do so, attach the following notices to the program.  It is safest
       
   301 to attach them to the start of each source file to most effectively
       
   302 convey the exclusion of warranty; and each file should have at least
       
   303 the "copyright" line and a pointer to where the full notice is found.
       
   304 
       
   305     <one line to give the program's name and a brief idea of what it does.>
       
   306     Copyright (C) <year>  <name of author>
       
   307 
       
   308     This program is free software; you can redistribute it and/or modify
       
   309     it under the terms of the GNU General Public License as published by
       
   310     the Free Software Foundation; either version 2 of the License, or
       
   311     (at your option) any later version.
       
   312 
       
   313     This program is distributed in the hope that it will be useful,
       
   314     but WITHOUT ANY WARRANTY; without even the implied warranty of
       
   315     MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
       
   316     GNU General Public License for more details.
       
   317 
       
   318     You should have received a copy of the GNU General Public License
       
   319     along with this program; if not, write to the Free Software
       
   320     Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
       
   321 
       
   322 
       
   323 Also add information on how to contact you by electronic and paper mail.
       
   324 
       
   325 If the program is interactive, make it output a short notice like this
       
   326 when it starts in an interactive mode:
       
   327 
       
   328     Gnomovision version 69, Copyright (C) year name of author
       
   329     Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
       
   330     This is free software, and you are welcome to redistribute it
       
   331     under certain conditions; type `show c' for details.
       
   332 
       
   333 The hypothetical commands `show w' and `show c' should show the appropriate
       
   334 parts of the General Public License.  Of course, the commands you use may
       
   335 be called something other than `show w' and `show c'; they could even be
       
   336 mouse-clicks or menu items--whatever suits your program.
       
   337 
       
   338 You should also get your employer (if you work as a programmer) or your
       
   339 school, if any, to sign a "copyright disclaimer" for the program, if
       
   340 necessary.  Here is a sample; alter the names:
       
   341 
       
   342   Yoyodyne, Inc., hereby disclaims all copyright interest in the program
       
   343   `Gnomovision' (which makes passes at compilers) written by James Hacker.

   348 This General Public License does not permit incorporating your program into
       
   349 proprietary programs.  If your program is a subroutine library, you may
       
   350 consider it more useful to permit linking proprietary applications with the
       
   351 library.  If this is what you want to do, use the GNU Library General
       
   352 Public License instead of this License.
