  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 jelson 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 jelson 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.

 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 jelson 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 jelson 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 jelson 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 jelson 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 jelson 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 jelson 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 jelson 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 jelson 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 jelson 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 jelson 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 jelson 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            	    How to Apply These Terms to Your New Programs
283            
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.

313            If the program is interactive, make it output a short notice like this
314            when it starts in an interactive mode:

316 jelson 1.1     Gnomovision version 69, Copyright (C) year  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:

336            This General Public License does not permit incorporating your program into
337 jelson 1.1 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.
