0. This License applies to any program or other work which contains a notice placed by the copyright
holder saying it may be distributed under the terms of this General Public License. The "Program", below,
refers to any such program or work, and a "work based on the Program" means either the Program or
any derivative work under copyright law: that is to say, a work containing the Program or a portion of it,
eitherverbatimorwithmodicationsand/ortranslatedintoanotherlanguage.(Hereinafter,translationis
includedwithoutlimitationintheterm"modication".)Eachlicenseeisaddressedas"you".
Activitiesotherthancopying,distributionandmodicationarenotcoveredbythisLicense;theyare
outside its scope. The act of running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the Program (independent of having been made
by running the Program). Whether that is true depends on what the Program does.
1.YoumaycopyanddistributeverbatimcopiesoftheProgram'ssourcecodeasyoureceiveit,inany
medium, provided that you conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the
absence of any warranty; and give any other recipients of the Program a copy of this License
along with the Program.
You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty
protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based

a)Youmustcausethemodiedlestocarryprominentnoticesstatingthatyouchangedthelesand

b) You must cause any work that you distribute or publish, that in whole or in part contains or is
derived from the Program or any part thereof, to be licensed as a whole at no charge to all third
parties under the terms of this License.
c)Ifthemodiedprogramnormallyreadscommandsinteractivelywhenrun,youmustcauseit,when
started running for such interactive use in the most ordinary way, to print or display an announcement
including an appropriate copyright notice and a notice that there is no warranty (or else, saying that
you provide a warranty) and that users may redistribute the program under these conditions, and
telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but
does not normally print such an announcement, your work based on the Program is not required to
print an announcement.)
Theserequirementsapplytothemodiedworkasawhole.Ifidentiablesectionsofthatworkarenot
derived from the Program, and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those sections when you distribute them as
separate works. But when you distribute the same sections as part of a whole which is a work based on
the Program, the distribution of the whole must be on the terms of this License, whose permissions for
other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by
you; rather, the intent is to exercise the right to control the distribution of derivative or
collective works based on the Program.
