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

  9             			    Preamble
 10             
 11               The licenses for most software are designed to take away your
 12             freedom to share and change it.  By contrast, the GNU General Public
 13             License is intended to guarantee your freedom to share and change free
 14             software--to make sure the software is free for all its users.  This
 15             General Public License applies to most of the Free Software
 16             Foundation's software and to any other program whose authors commit to
 17             using it.  (Some other Free Software Foundation software is covered by
 18             the GNU Library General Public License instead.)  You can apply it to
 19             your programs, too.
 20             
 21               When we speak of free software, we are referring to freedom, not
 22 rizwank 1.1 price.  Our General Public Licenses are designed to make sure that you
 23             have the freedom to distribute copies of free software (and charge for
 24             this service if you wish), that you receive source code or can get it
 25             if you want it, that you can change the software or use pieces of it
 26             in new free programs; and that you know you can do these things.
 27             
 28               To protect your rights, we need to make restrictions that forbid
 29             anyone to deny you these rights or to ask you to surrender the rights.
 30             These restrictions translate to certain responsibilities for you if you
 31             distribute copies of the software, or if you modify it.
 32             
 33               For example, if you distribute copies of such a program, whether
 34             gratis or for a fee, you must give the recipients all the rights that
 35             you have.  You must make sure that they, too, receive or can get the
 36             source code.  And you must show them these terms so they know their
 37             rights.
 38             
 39               We protect your rights with two steps: (1) copyright the software, and
 40             (2) offer you this license which gives you legal permission to copy,
 41             distribute and/or modify the software.
 42             
 43 rizwank 1.1   Also, for each author's protection and ours, we want to make certain
 44             that everyone understands that there is no warranty for this free
 45             software.  If the software is modified by someone else and passed on, we
 46             want its recipients to know that what they have is not the original, so
 47             that any problems introduced by others will not reflect on the original
 48             authors' reputations.
 49             
 50               Finally, any free program is threatened constantly by software
 51             patents.  We wish to avoid the danger that redistributors of a free
 52             program will individually obtain patent licenses, in effect making the
 53             program proprietary.  To prevent this, we have made it clear that any
 54             patent must be licensed for everyone's free use or not licensed at all.
 55             
 56               The precise terms and conditions for copying, distribution and
 57             modification follow.
 58             
 59             		    GNU GENERAL PUBLIC LICENSE
 60                TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
 61             
 62               0. This License applies to any program or other work which contains
 63             a notice placed by the copyright holder saying it may be distributed
 64 rizwank 1.1 under the terms of this General Public License.  The "Program", below,
 65             refers to any such program or work, and a "work based on the Program"
 66             means either the Program or any derivative work under copyright law:
 67             that is to say, a work containing the Program or a portion of it,
 68             either verbatim or with modifications and/or translated into another
 69             language.  (Hereinafter, translation is included without limitation in
 70             the term "modification".)  Each licensee is addressed as "you".
 71             
 72             Activities other than copying, distribution and modification are not
 73             covered by this License; they are outside its scope.  The act of
 74             running the Program is not restricted, and the output from the Program
 75             is covered only if its contents constitute a work based on the
 76             Program (independent of having been made by running the Program).
 77             Whether that is true depends on what the Program does.
 78             
 79               1. You may copy and distribute verbatim copies of the Program's
 80             source code as you receive it, in any medium, provided that you
 81             conspicuously and appropriately publish on each copy an appropriate
 82             copyright notice and disclaimer of warranty; keep intact all the
 83             notices that refer to this License and to the absence of any warranty;
 84             and give any other recipients of the Program a copy of this License
 85 rizwank 1.1 along with the Program.
 86             
 87             You may charge a fee for the physical act of transferring a copy, and
 88             you may at your option offer warranty protection in exchange for a fee.
 89             
 90               2. You may modify your copy or copies of the Program or any portion
 91             of it, thus forming a work based on the Program, and copy and
 92             distribute such modifications or work under the terms of Section 1
 93             above, provided that you also meet all of these conditions:
 94             
 95                 a) You must cause the modified files to carry prominent notices
 96                 stating that you changed the files and the date of any change.
 97             
 98                 b) You must cause any work that you distribute or publish, that in
 99                 whole or in part contains or is derived from the Program or any
100                 part thereof, to be licensed as a whole at no charge to all third
101                 parties under the terms of this License.
102             
103                 c) If the modified program normally reads commands interactively
104                 when run, you must cause it, when started running for such
105                 interactive use in the most ordinary way, to print or display an
106 rizwank 1.1     announcement including an appropriate copyright notice and a
107                 notice that there is no warranty (or else, saying that you provide
108                 a warranty) and that users may redistribute the program under
109                 these conditions, and telling the user how to view a copy of this
110                 License.  (Exception: if the Program itself is interactive but
111                 does not normally print such an announcement, your work based on
112                 the Program is not required to print an announcement.)
113             
114             These requirements apply to the modified work as a whole.  If
115             identifiable sections of that work are not derived from the Program,
116             and can be reasonably considered independent and separate works in
117             themselves, then this License, and its terms, do not apply to those
118             sections when you distribute them as separate works.  But when you
119             distribute the same sections as part of a whole which is a work based
120             on the Program, the distribution of the whole must be on the terms of
121             this License, whose permissions for other licensees extend to the
122             entire whole, and thus to each and every part regardless of who wrote it.
123             
124             Thus, it is not the intent of this section to claim rights or contest
125             your rights to work written entirely by you; rather, the intent is to
126             exercise the right to control the distribution of derivative or
127 rizwank 1.1 collective works based on the Program.
128             
129             In addition, mere aggregation of another work not based on the Program
130             with the Program (or with a work based on the Program) on a volume of
131             a storage or distribution medium does not bring the other work under
132             the scope of this License.
133             
134               3. You may copy and distribute the Program (or a work based on it,
135             under Section 2) in object code or executable form under the terms of
136             Sections 1 and 2 above provided that you also do one of the following:
137             
138                 a) Accompany it with the complete corresponding machine-readable
139                 source code, which must be distributed under the terms of Sections
140                 1 and 2 above on a medium customarily used for software interchange; or,
141             
142                 b) Accompany it with a written offer, valid for at least three
143                 years, to give any third party, for a charge no more than your
144                 cost of physically performing source distribution, a complete
145                 machine-readable copy of the corresponding source code, to be
146                 distributed under the terms of Sections 1 and 2 above on a medium
147                 customarily used for software interchange; or,
148 rizwank 1.1 
149                 c) Accompany it with the information you received as to the offer
150                 to distribute corresponding source code.  (This alternative is
151                 allowed only for noncommercial distribution and only if you
152                 received the program in object code or executable form with such
153                 an offer, in accord with Subsection b above.)
154             
155             The source code for a work means the preferred form of the work for
156             making modifications to it.  For an executable work, complete source
157             code means all the source code for all modules it contains, plus any
158             associated interface definition files, plus the scripts used to
159             control compilation and installation of the executable.  However, as a
160             special exception, the source code distributed need not include
161             anything that is normally distributed (in either source or binary
162             form) with the major components (compiler, kernel, and so on) of the
163             operating system on which the executable runs, unless that component
164             itself accompanies the executable.
165             
166             If distribution of executable or object code is made by offering
167             access to copy from a designated place, then offering equivalent
168             access to copy the source code from the same place counts as
169 rizwank 1.1 distribution of the source code, even though third parties are not
170             compelled to copy the source along with the object code.
171             
172               4. You may not copy, modify, sublicense, or distribute the Program
173             except as expressly provided under this License.  Any attempt
174             otherwise to copy, modify, sublicense or distribute the Program is
175             void, and will automatically terminate your rights under this License.
176             However, parties who have received copies, or rights, from you under
177             this License will not have their licenses terminated so long as such
178             parties remain in full compliance.
179             
180               5. You are not required to accept this License, since you have not
181             signed it.  However, nothing else grants you permission to modify or
182             distribute the Program or its derivative works.  These actions are
183             prohibited by law if you do not accept this License.  Therefore, by
184             modifying or distributing the Program (or any work based on the
185             Program), you indicate your acceptance of this License to do so, and
186             all its terms and conditions for copying, distributing or modifying
187             the Program or works based on it.
188             
189               6. Each time you redistribute the Program (or any work based on the
190 rizwank 1.1 Program), the recipient automatically receives a license from the
191             original licensor to copy, distribute or modify the Program subject to
192             these terms and conditions.  You may not impose any further
193             restrictions on the recipients' exercise of the rights granted herein.
194             You are not responsible for enforcing compliance by third parties to
195             this License.
196             
197               7. If, as a consequence of a court judgment or allegation of patent
198             infringement or for any other reason (not limited to patent issues),
199             conditions are imposed on you (whether by court order, agreement or
200             otherwise) that contradict the conditions of this License, they do not
201             excuse you from the conditions of this License.  If you cannot
202             distribute so as to satisfy simultaneously your obligations under this
203             License and any other pertinent obligations, then as a consequence you
204             may not distribute the Program at all.  For example, if a patent
205             license would not permit royalty-free redistribution of the Program by
206             all those who receive copies directly or indirectly through you, then
207             the only way you could satisfy both it and this License would be to
208             refrain entirely from distribution of the Program.
209             
210             If any portion of this section is held invalid or unenforceable under
211 rizwank 1.1 any particular circumstance, the balance of the section is intended to
212             apply and the section as a whole is intended to apply in other
213             circumstances.
214             
215             It is not the purpose of this section to induce you to infringe any
216             patents or other property right claims or to contest validity of any
217             such claims; this section has the sole purpose of protecting the
218             integrity of the free software distribution system, which is
219             implemented by public license practices.  Many people have made
220             generous contributions to the wide range of software distributed
221             through that system in reliance on consistent application of that
222             system; it is up to the author/donor to decide if he or she is willing
223             to distribute software through any other system and a licensee cannot
224             impose that choice.
225             
226             This section is intended to make thoroughly clear what is believed to
227             be a consequence of the rest of this License.
228             
229               8. If the distribution and/or use of the Program is restricted in
230             certain countries either by patents or by copyrighted interfaces, the
231             original copyright holder who places the Program under this License
232 rizwank 1.1 may add an explicit geographical distribution limitation excluding
233             those countries, so that distribution is permitted only in or among
234             countries not thus excluded.  In such case, this License incorporates
235             the limitation as if written in the body of this License.
236             
237               9. The Free Software Foundation may publish revised and/or new versions
238             of the General Public License from time to time.  Such new versions will
239             be similar in spirit to the present version, but may differ in detail to
240             address new problems or concerns.
241             
242             Each version is given a distinguishing version number.  If the Program
243             specifies a version number of this License which applies to it and "any
244             later version", you have the option of following the terms and conditions
245             either of that version or of any later version published by the Free
246             Software Foundation.  If the Program does not specify a version number of
247             this License, you may choose any version ever published by the Free Software
248             Foundation.
249             
250               10. If you wish to incorporate parts of the Program into other free
251             programs whose distribution conditions are different, write to the author
252             to ask for permission.  For software which is copyrighted by the Free
253 rizwank 1.1 Software Foundation, write to the Free Software Foundation; we sometimes
254             make exceptions for this.  Our decision will be guided by the two goals
255             of preserving the free status of all derivatives of our free software and
256             of promoting the sharing and reuse of software generally.
257             
258             			    NO WARRANTY
259             
260               11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
261             FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
262             OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
263             PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
264             OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
265             MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
266             TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
267             PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
268             REPAIR OR CORRECTION.
269             
270               12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
271             WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
272             REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
273             INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
274 rizwank 1.1 OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
275             TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
276             YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
277             PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
278             POSSIBILITY OF SUCH DAMAGES.
279             
280             		     END OF TERMS AND CONDITIONS
281             
282             	Appendix: How to Apply These Terms to Your New Programs

284               If you develop a new program, and you want it to be of the greatest
285             possible use to the public, the best way to achieve this is to make it
286             free software which everyone can redistribute and change under these terms.
287             
288               To do so, attach the following notices to the program.  It is safest
289             to attach them to the start of each source file to most effectively
290             convey the exclusion of warranty; and each file should have at least
291             the "copyright" line and a pointer to where the full notice is found.
292             
293                 <one line to give the program's name and a brief idea of what it does.>

310             Also add information on how to contact you by electronic and paper mail.
311             
312             If the program is interactive, make it output a short notice like this
313             when it starts in an interactive mode:
314             
315                 Gnomovision version 69, Copyright (C) 19yy name of author
316 rizwank 1.1     Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
317                 This is free software, and you are welcome to redistribute it
318                 under certain conditions; type `show c' for details.
319             
320             The hypothetical commands `show w' and `show c' should show the appropriate
321             parts of the General Public License.  Of course, the commands you use may
322             be called something other than `show w' and `show c'; they could even be
323             mouse-clicks or menu items--whatever suits your program.
324             
325             You should also get your employer (if you work as a programmer) or your
326             school, if any, to sign a "copyright disclaimer" for the program, if
327             necessary.  Here is a sample; alter the names:

329               Yoyodyne, Inc., hereby disclaims all copyright interest in the program
330               `Gnomovision' (which makes passes at compilers) written by James Hacker.

335             This General Public License does not permit incorporating your program into
336             proprietary programs.  If your program is a subroutine library, you may
337 rizwank 1.1 consider it more useful to permit linking proprietary applications with the
338             library.  If this is what you want to do, use the GNU Library General
339             Public License instead of this License.
