     1.5 +		       Version 2, June 1991
     1.6 +
     1.7 + Copyright (C) 1989, 1991 Free Software Foundation, Inc.
     1.8 +                       59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
     1.9 + Everyone is permitted to copy and distribute verbatim copies
    1.10 + of this license document, but changing it is not allowed.
    1.11 +
    1.12 +			    Preamble
    1.13 +
    1.14 +  The licenses for most software are designed to take away your
    1.15 +freedom to share and change it.  By contrast, the GNU General Public
    1.16 +License is intended to guarantee your freedom to share and change free
    1.17 +software--to make sure the software is free for all its users.  This
    1.18 +General Public License applies to most of the Free Software
    1.19 +Foundation's software and to any other program whose authors commit to
    1.20 +using it.  (Some other Free Software Foundation software is covered by
    1.21 +the GNU Library General Public License instead.)  You can apply it to
    1.22 +your programs, too.
    1.23 +
    1.24 +  When we speak of free software, we are referring to freedom, not
    1.25 +price.  Our General Public Licenses are designed to make sure that you
    1.26 +have the freedom to distribute copies of free software (and charge for
    1.27 +this service if you wish), that you receive source code or can get it
    1.28 +if you want it, that you can change the software or use pieces of it
    1.29 +in new free programs; and that you know you can do these things.
    1.30 +
    1.31 +  To protect your rights, we need to make restrictions that forbid
    1.32 +anyone to deny you these rights or to ask you to surrender the rights.
    1.33 +These restrictions translate to certain responsibilities for you if you
    1.34 +distribute copies of the software, or if you modify it.
    1.35 +
    1.36 +  For example, if you distribute copies of such a program, whether
    1.37 +gratis or for a fee, you must give the recipients all the rights that
    1.38 +you have.  You must make sure that they, too, receive or can get the
    1.39 +source code.  And you must show them these terms so they know their
    1.40 +rights.
    1.41 +
    1.42 +  We protect your rights with two steps: (1) copyright the software, and
    1.43 +(2) offer you this license which gives you legal permission to copy,
    1.44 +distribute and/or modify the software.
    1.45 +
    1.46 +  Also, for each author's protection and ours, we want to make certain
    1.47 +that everyone understands that there is no warranty for this free
    1.48 +software.  If the software is modified by someone else and passed on, we
    1.49 +want its recipients to know that what they have is not the original, so
    1.50 +that any problems introduced by others will not reflect on the original
    1.51 +authors' reputations.
    1.52 +
    1.53 +  Finally, any free program is threatened constantly by software
    1.54 +patents.  We wish to avoid the danger that redistributors of a free
    1.55 +program will individually obtain patent licenses, in effect making the
    1.56 +program proprietary.  To prevent this, we have made it clear that any
    1.57 +patent must be licensed for everyone's free use or not licensed at all.
    1.58 +
    1.59 +  The precise terms and conditions for copying, distribution and
    1.60 +modification follow.
    1.61 +
    1.62 +		    GNU GENERAL PUBLIC LICENSE
    1.63 +   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
    1.64 +
    1.65 +  0. This License applies to any program or other work which contains
    1.66 +a notice placed by the copyright holder saying it may be distributed
    1.67 +under the terms of this General Public License.  The "Program", below,
    1.68 +refers to any such program or work, and a "work based on the Program"
    1.69 +means either the Program or any derivative work under copyright law:
    1.70 +that is to say, a work containing the Program or a portion of it,
    1.71 +either verbatim or with modifications and/or translated into another
    1.72 +language.  (Hereinafter, translation is included without limitation in
    1.73 +the term "modification".)  Each licensee is addressed as "you".
    1.74 +
    1.75 +Activities other than copying, distribution and modification are not
    1.76 +covered by this License; they are outside its scope.  The act of
    1.77 +running the Program is not restricted, and the output from the Program
    1.78 +is covered only if its contents constitute a work based on the
    1.79 +Program (independent of having been made by running the Program).
    1.80 +Whether that is true depends on what the Program does.
    1.81 +
    1.82 +  1. You may copy and distribute verbatim copies of the Program's
    1.83 +source code as you receive it, in any medium, provided that you
    1.84 +conspicuously and appropriately publish on each copy an appropriate
    1.85 +copyright notice and disclaimer of warranty; keep intact all the
    1.86 +notices that refer to this License and to the absence of any warranty;
    1.87 +and give any other recipients of the Program a copy of this License
    1.88 +along with the Program.
    1.89 +
    1.90 +You may charge a fee for the physical act of transferring a copy, and
    1.91 +you may at your option offer warranty protection in exchange for a fee.
    1.92 +
    1.93 +  2. You may modify your copy or copies of the Program or any portion
    1.94 +of it, thus forming a work based on the Program, and copy and
    1.95 +distribute such modifications or work under the terms of Section 1
    1.96 +above, provided that you also meet all of these conditions:
    1.97 +
    1.98 +    a) You must cause the modified files to carry prominent notices
    1.99 +    stating that you changed the files and the date of any change.
   1.100 +
   1.101 +    b) You must cause any work that you distribute or publish, that in
   1.102 +    whole or in part contains or is derived from the Program or any
   1.103 +    part thereof, to be licensed as a whole at no charge to all third
   1.104 +    parties under the terms of this License.
   1.105 +
   1.106 +    c) If the modified program normally reads commands interactively
   1.107 +    when run, you must cause it, when started running for such
   1.108 +    interactive use in the most ordinary way, to print or display an
   1.109 +    announcement including an appropriate copyright notice and a
   1.110 +    notice that there is no warranty (or else, saying that you provide
   1.111 +    a warranty) and that users may redistribute the program under
   1.112 +    these conditions, and telling the user how to view a copy of this
   1.113 +    License.  (Exception: if the Program itself is interactive but
   1.114 +    does not normally print such an announcement, your work based on
   1.115 +    the Program is not required to print an announcement.)
   1.116 +
   1.117 +These requirements apply to the modified work as a whole.  If
   1.118 +identifiable sections of that work are not derived from the Program,
   1.119 +and can be reasonably considered independent and separate works in
   1.120 +themselves, then this License, and its terms, do not apply to those
   1.121 +sections when you distribute them as separate works.  But when you
   1.122 +distribute the same sections as part of a whole which is a work based
   1.123 +on the Program, the distribution of the whole must be on the terms of
   1.124 +this License, whose permissions for other licensees extend to the
   1.125 +entire whole, and thus to each and every part regardless of who wrote it.
   1.126 +
   1.127 +Thus, it is not the intent of this section to claim rights or contest
   1.128 +your rights to work written entirely by you; rather, the intent is to
   1.129 +exercise the right to control the distribution of derivative or
   1.130 +collective works based on the Program.
   1.131 +
   1.132 +In addition, mere aggregation of another work not based on the Program
   1.133 +with the Program (or with a work based on the Program) on a volume of
   1.134 +a storage or distribution medium does not bring the other work under
   1.135 +the scope of this License.
   1.136 +
   1.137 +  3. You may copy and distribute the Program (or a work based on it,
   1.138 +under Section 2) in object code or executable form under the terms of
   1.139 +Sections 1 and 2 above provided that you also do one of the following:
   1.140 +
   1.141 +    a) Accompany it with the complete corresponding machine-readable
   1.142 +    source code, which must be distributed under the terms of Sections
   1.143 +    1 and 2 above on a medium customarily used for software interchange; or,
   1.144 +
   1.145 +    b) Accompany it with a written offer, valid for at least three
   1.146 +    years, to give any third party, for a charge no more than your
   1.147 +    cost of physically performing source distribution, a complete
   1.148 +    machine-readable copy of the corresponding source code, to be
   1.149 +    distributed under the terms of Sections 1 and 2 above on a medium
   1.150 +    customarily used for software interchange; or,
   1.151 +
   1.152 +    c) Accompany it with the information you received as to the offer
   1.153 +    to distribute corresponding source code.  (This alternative is
   1.154 +    allowed only for noncommercial distribution and only if you
   1.155 +    received the program in object code or executable form with such
   1.156 +    an offer, in accord with Subsection b above.)
   1.157 +
   1.158 +The source code for a work means the preferred form of the work for
   1.159 +making modifications to it.  For an executable work, complete source
   1.160 +code means all the source code for all modules it contains, plus any
   1.161 +associated interface definition files, plus the scripts used to
   1.162 +control compilation and installation of the executable.  However, as a
   1.163 +special exception, the source code distributed need not include
   1.164 +anything that is normally distributed (in either source or binary
   1.165 +form) with the major components (compiler, kernel, and so on) of the
   1.166 +operating system on which the executable runs, unless that component
   1.167 +itself accompanies the executable.
   1.168 +
   1.169 +If distribution of executable or object code is made by offering
   1.170 +access to copy from a designated place, then offering equivalent
   1.171 +access to copy the source code from the same place counts as
   1.172 +distribution of the source code, even though third parties are not
   1.173 +compelled to copy the source along with the object code.
   1.174 +
   1.175 +  4. You may not copy, modify, sublicense, or distribute the Program
   1.176 +except as expressly provided under this License.  Any attempt
   1.177 +otherwise to copy, modify, sublicense or distribute the Program is
   1.178 +void, and will automatically terminate your rights under this License.
   1.179 +However, parties who have received copies, or rights, from you under
   1.180 +this License will not have their licenses terminated so long as such
   1.181 +parties remain in full compliance.
   1.182 +
   1.183 +  5. You are not required to accept this License, since you have not
   1.184 +signed it.  However, nothing else grants you permission to modify or
   1.185 +distribute the Program or its derivative works.  These actions are
   1.186 +prohibited by law if you do not accept this License.  Therefore, by
   1.187 +modifying or distributing the Program (or any work based on the
   1.188 +Program), you indicate your acceptance of this License to do so, and
   1.189 +all its terms and conditions for copying, distributing or modifying
   1.190 +the Program or works based on it.
   1.191 +
   1.192 +  6. Each time you redistribute the Program (or any work based on the
   1.193 +Program), the recipient automatically receives a license from the
   1.194 +original licensor to copy, distribute or modify the Program subject to
   1.195 +these terms and conditions.  You may not impose any further
   1.196 +restrictions on the recipients' exercise of the rights granted herein.
   1.197 +You are not responsible for enforcing compliance by third parties to
   1.198 +this License.
   1.199 +
   1.200 +  7. If, as a consequence of a court judgment or allegation of patent
   1.201 +infringement or for any other reason (not limited to patent issues),
   1.202 +conditions are imposed on you (whether by court order, agreement or
   1.203 +otherwise) that contradict the conditions of this License, they do not
   1.204 +excuse you from the conditions of this License.  If you cannot
   1.205 +distribute so as to satisfy simultaneously your obligations under this
   1.206 +License and any other pertinent obligations, then as a consequence you
   1.207 +may not distribute the Program at all.  For example, if a patent
   1.208 +license would not permit royalty-free redistribution of the Program by
   1.209 +all those who receive copies directly or indirectly through you, then
   1.210 +the only way you could satisfy both it and this License would be to
   1.211 +refrain entirely from distribution of the Program.
   1.212 +
   1.213 +If any portion of this section is held invalid or unenforceable under
   1.214 +any particular circumstance, the balance of the section is intended to
   1.215 +apply and the section as a whole is intended to apply in other
   1.216 +circumstances.
   1.217 +
   1.218 +It is not the purpose of this section to induce you to infringe any
   1.219 +patents or other property right claims or to contest validity of any
   1.220 +such claims; this section has the sole purpose of protecting the
   1.221 +integrity of the free software distribution system, which is
   1.222 +implemented by public license practices.  Many people have made
   1.223 +generous contributions to the wide range of software distributed
   1.224 +through that system in reliance on consistent application of that
   1.225 +system; it is up to the author/donor to decide if he or she is willing
   1.226 +to distribute software through any other system and a licensee cannot
   1.227 +impose that choice.
   1.228 +
   1.229 +This section is intended to make thoroughly clear what is believed to
   1.230 +be a consequence of the rest of this License.
   1.231 +
   1.232 +  8. If the distribution and/or use of the Program is restricted in
   1.233 +certain countries either by patents or by copyrighted interfaces, the
   1.234 +original copyright holder who places the Program under this License
   1.235 +may add an explicit geographical distribution limitation excluding
   1.236 +those countries, so that distribution is permitted only in or among
   1.237 +countries not thus excluded.  In such case, this License incorporates
   1.238 +the limitation as if written in the body of this License.
   1.239 +
   1.240 +  9. The Free Software Foundation may publish revised and/or new versions
   1.241 +of the General Public License from time to time.  Such new versions will
   1.242 +be similar in spirit to the present version, but may differ in detail to
   1.243 +address new problems or concerns.
   1.244 +
   1.245 +Each version is given a distinguishing version number.  If the Program
   1.246 +specifies a version number of this License which applies to it and "any
   1.247 +later version", you have the option of following the terms and conditions
   1.248 +either of that version or of any later version published by the Free
   1.249 +Software Foundation.  If the Program does not specify a version number of
   1.250 +this License, you may choose any version ever published by the Free Software
   1.251 +Foundation.
   1.252 +
   1.253 +  10. If you wish to incorporate parts of the Program into other free
   1.254 +programs whose distribution conditions are different, write to the author
   1.255 +to ask for permission.  For software which is copyrighted by the Free
   1.256 +Software Foundation, write to the Free Software Foundation; we sometimes
   1.257 +make exceptions for this.  Our decision will be guided by the two goals
   1.258 +of preserving the free status of all derivatives of our free software and
   1.259 +of promoting the sharing and reuse of software generally.
   1.260 +
   1.261 +			    NO WARRANTY
   1.262 +
   1.263 +  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
   1.264 +FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
   1.265 +OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
   1.266 +PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
   1.267 +OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
   1.268 +MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
   1.269 +TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
   1.270 +PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
   1.271 +REPAIR OR CORRECTION.
   1.272 +
   1.273 +  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
   1.274 +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
   1.275 +REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
   1.276 +INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
   1.277 +OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
   1.278 +TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
   1.279 +YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
   1.280 +PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
   1.281 +POSSIBILITY OF SUCH DAMAGES.
   1.282 +
   1.283 +		     END OF TERMS AND CONDITIONS
   1.284 +
   1.285 +	    How to Apply These Terms to Your New Programs
   1.286 +
   1.287 +  If you develop a new program, and you want it to be of the greatest
   1.288 +possible use to the public, the best way to achieve this is to make it
   1.289 +free software which everyone can redistribute and change under these terms.
   1.290 +
   1.291 +  To do so, attach the following notices to the program.  It is safest
   1.292 +to attach them to the start of each source file to most effectively
   1.293 +convey the exclusion of warranty; and each file should have at least
   1.294 +the "copyright" line and a pointer to where the full notice is found.
   1.295 +
   1.296 +    <one line to give the program's name and a brief idea of what it does.>
   1.297 +    Copyright (C) <year>  <name of author>
   1.298 +
   1.299 +    This program is free software; you can redistribute it and/or modify
   1.300 +    it under the terms of the GNU General Public License as published by
   1.301 +    the Free Software Foundation; either version 2 of the License, or
   1.302 +    (at your option) any later version.
   1.303 +
   1.304 +    This program is distributed in the hope that it will be useful,
   1.305 +    but WITHOUT ANY WARRANTY; without even the implied warranty of
   1.306 +    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
   1.307 +    GNU General Public License for more details.
   1.308 +
   1.309 +    You should have received a copy of the GNU General Public License
   1.310 +    along with this program; if not, write to the Free Software
   1.311 +    Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
   1.312 +
   1.313 +
   1.314 +Also add information on how to contact you by electronic and paper mail.
   1.315 +
   1.316 +If the program is interactive, make it output a short notice like this
   1.317 +when it starts in an interactive mode:
   1.318 +
   1.319 +    Gnomovision version 69, Copyright (C) year name of author
   1.320 +    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
   1.321 +    This is free software, and you are welcome to redistribute it
   1.322 +    under certain conditions; type `show c' for details.
   1.323 +
   1.324 +The hypothetical commands `show w' and `show c' should show the appropriate
   1.325 +parts of the General Public License.  Of course, the commands you use may
   1.326 +be called something other than `show w' and `show c'; they could even be
   1.327 +mouse-clicks or menu items--whatever suits your program.
   1.328 +
   1.329 +You should also get your employer (if you work as a programmer) or your
   1.330 +school, if any, to sign a "copyright disclaimer" for the program, if
   1.331 +necessary.  Here is a sample; alter the names:
   1.332 +
   1.333 +  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
   1.334 +  `Gnomovision' (which makes passes at compilers) written by James Hacker.

   1.338 +
   1.339 +This General Public License does not permit incorporating your program into
   1.340 +proprietary programs.  If your program is a subroutine library, you may
   1.341 +consider it more useful to permit linking proprietary applications with the
   1.342 +library.  If this is what you want to do, use the GNU Library General
   1.343 +Public License instead of this License.
   1.344 +
   1.345 +
