   127 These requirements apply to the modified work as a whole.  If

   128 identifiable sections of that work are not derived from the Program,

   130 themselves, then this License, and its terms, do not apply to those
   131 	#
   131 sections when you distribute them as separate works.  But when you

   135 entire whole, and thus to each and every part regardless of who wrote it.
   136 
   136 
       
   137 Thus, it is not the intent of this section to claim rights or contest
       
   138 your rights to work written entirely by you; rather, the intent is to
       
   139 exercise the right to control the distribution of derivative or
       
   140 collective works based on the Program.
       
   141 
       
   142 In addition, mere aggregation of another work not based on the Program
       
   143 with the Program (or with a work based on the Program) on a volume of
       
   144 a storage or distribution medium does not bring the other work under
       
   145 the scope of this License.
       
   146 
       
   147   3. You may copy and distribute the Program (or a work based on it,
       
   148 under Section 2) in object code or executable form under the terms of
       
   149 Sections 1 and 2 above provided that you also do one of the following:
       
   150 
       
   151     a) Accompany it with the complete corresponding machine-readable
       
   152     source code, which must be distributed under the terms of Sections
       
   153     1 and 2 above on a medium customarily used for software interchange; or,
       
   154 
       
   155     b) Accompany it with a written offer, valid for at least three
       
   156     years, to give any third party, for a charge no more than your
       
   157     cost of physically performing source distribution, a complete
       
   158     machine-readable copy of the corresponding source code, to be
       
   159     distributed under the terms of Sections 1 and 2 above on a medium
       
   160     customarily used for software interchange; or,
       
   161 
       
   162     c) Accompany it with the information you received as to the offer
       
   163     to distribute corresponding source code.  (This alternative is
       
   164     allowed only for noncommercial distribution and only if you
       
   165     received the program in object code or executable form with such
       
   166     an offer, in accord with Subsection b above.)
       
   167 
       
   168 The source code for a work means the preferred form of the work for
       
   169 making modifications to it.  For an executable work, complete source
       
   170 code means all the source code for all modules it contains, plus any
       
   171 associated interface definition files, plus the scripts used to
       
   172 control compilation and installation of the executable.  However, as a
       
   173 special exception, the source code distributed need not include
       
   174 anything that is normally distributed (in either source or binary
       
   175 form) with the major components (compiler, kernel, and so on) of the
       
   176 operating system on which the executable runs, unless that component
       
   177 itself accompanies the executable.
       
   178 
       
   179 If distribution of executable or object code is made by offering
       
   180 access to copy from a designated place, then offering equivalent
       
   181 access to copy the source code from the same place counts as
       
   182 distribution of the source code, even though third parties are not
       
   183 compelled to copy the source along with the object code.
       
   184 
       
   185   4. You may not copy, modify, sublicense, or distribute the Program
       
   186 except as expressly provided under this License.  Any attempt
       
   187 otherwise to copy, modify, sublicense or distribute the Program is
       
   188 void, and will automatically terminate your rights under this License.
       
   189 However, parties who have received copies, or rights, from you under
       
   190 this License will not have their licenses terminated so long as such
       
   191 parties remain in full compliance.
       
   192 
       
   193   5. You are not required to accept this License, since you have not
       
   194 signed it.  However, nothing else grants you permission to modify or
       
   195 distribute the Program or its derivative works.  These actions are
       
   196 prohibited by law if you do not accept this License.  Therefore, by
       
   197 modifying or distributing the Program (or any work based on the
       
   198 Program), you indicate your acceptance of this License to do so, and
       
   199 all its terms and conditions for copying, distributing or modifying
       
   200 the Program or works based on it.
       
   201 
       
   202   6. Each time you redistribute the Program (or any work based on the
       
   203 Program), the recipient automatically receives a license from the
       
   204 original licensor to copy, distribute or modify the Program subject to
       
   205 these terms and conditions.  You may not impose any further
       
   206 restrictions on the recipients' exercise of the rights granted herein.
       
   207 You are not responsible for enforcing compliance by third parties to
       
   208 this License.
       
   209 
       
   210   7. If, as a consequence of a court judgment or allegation of patent
       
   211 infringement or for any other reason (not limited to patent issues),
       
   212 conditions are imposed on you (whether by court order, agreement or
       
   213 otherwise) that contradict the conditions of this License, they do not
       
   214 excuse you from the conditions of this License.  If you cannot
       
   215 distribute so as to satisfy simultaneously your obligations under this
       
   216 License and any other pertinent obligations, then as a consequence you
       
   217 may not distribute the Program at all.  For example, if a patent
       
   218 license would not permit royalty-free redistribution of the Program by
       
   219 all those who receive copies directly or indirectly through you, then
       
   220 the only way you could satisfy both it and this License would be to
       
   221 refrain entirely from distribution of the Program.
       
   222 
       
   223 If any portion of this section is held invalid or unenforceable under
       
   224 any particular circumstance, the balance of the section is intended to
       
   225 apply and the section as a whole is intended to apply in other
       
   226 circumstances.
       
   227 
       
   228 It is not the purpose of this section to induce you to infringe any
       
   229 patents or other property right claims or to contest validity ofany
       
   230 such claims; this section has the sole purpose of protecting the
       
   231 integrity of the free software distribution system, which is
       
   232 implemented by public license practices.  Many people have made
       
   233 generous contributions to the wide range of software distributed
       
   234 through that system in reliance on consistent application of that
       
   235 system; it is up to the author/donor to decide if he or she is willing
       
   236 to distribute software through any other system and a licensee cannot
       
   237 impose that choice.
       
   238 
       
   239 This section is intended to make thoroughly clear what is believed to
       
   240 be a consequence of the rest of this License.
       
   241 
       
   242   8. If the distribution and/or use of the Program is restricted in
       
   243 certain countries either by patents or by copyrighted interfaces, the
       
   244 original copyright holder who places the Program under this License
       
   245 may add an explicit geographical distribution limitation excluding
       
   246 those countries, so that distribution is permitted only in or among
       
   247 countries not thus excluded.  In such case, this License incorporates
       
   248 the limn the body of this License.
       
   249 
       
   250   9. The Free Software Foundation may publish revised and/or new versions
       
   251 of the General Public License from time to time.  Such new versions will
       
   252 be similar in spirit to the present version, but may differ in detail to
       
   253 address new problems or concerns.
       
   254 
       
   255 Each version is given a distinguishing version number.  If the Program
       
   256 specifies a version number of this License which applies to it and "any
       
   257 later version", you have the option of following the terms and conditions
       
   258 either of that version or of any later version published by the Free
       
   259 Software Foundation.  If the Program does not specify a version number of
       
   260 this License, you may choose any version ever published by the Free Software
       
   261 Foundation.
       
   262 
       
   263   10. If you wish to incorporate parts of the Program into other free
       
   264 programs whose distribution conditions are different, write to the author
       
   265 to ask for permission.  For software which is copyrighted by the Free
       
   266 Software Foundation, write to the Free Software Foundation; we sometimes
       
   267 mak  Our decision will be guided by the two goals
       
   268 of preserving the free status of all derivatives of our free software and
       
   269 of promoting the sharing and reuse of software generally.

   271 			    NO WARRANTY
       
   272 
       
   273   11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
       
   274 FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
       
   275 OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
       
   276 PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
       
   277 OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
       
   278 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
       
   279 TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
       
   280 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
       
   281 REPAIR OR CORRECTION.
       
   282 
       
   283   12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
       
   284 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
       
   285 REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
       
   286 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
       
   287 OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
       
   288 TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
       
   289 YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
       
   290 PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
       
   291 POSSIBILITY OF SUCH DAMAGES.

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

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