Thus, it is not the inten t of this section to cla im rights or contes t your rights to wor k written enti rely by you;
rather, the intent is to exe rcise the right to con trol the distri bution of deriva tive or collective w orks based
on the Program.
In addition, mere ag gregation of anot her work not based on t he Program wit h the Program (or with a wo rk
based on the Program) on a vo lume of a storage or di stribution me dium does not bring t he other work
under the scope of this Lice nse.
3. You may copy and distribute t he Program (or a work ba sed on it, under Sec tion 2) in object code o r
executable form und er the terms of Sec tions 1 and 2 above provi ded that you also do one of t he following:
a) Accompany i t with the complete cor responding mach ine-readable s ource code, which mus t be
distributed und er the terms of Sec tions 1 and 2 above on a medi um customarily us ed for software
interchange; or,
b) Accompany it with a w ritten offe r, valid for at least thr ee years, to give any t hird party, for a cha rge no
more than your cost of physi cally perfor ming source distr ibution, a comple te machine-read able copy
of the corresponding s ource code, to be dist ributed under t he terms of Sectio ns 1 and 2 above on a
medium customaril y used for softwar e interchange; or,
c) Accompany i t with the informat ion you received as to t he offer to distr ibute correspon ding source
code. (This alter native is allowed onl y for noncommercial d istribution a nd only if you received t he
program in object co de or executable for m with such an offe r, in accord with Subsec tion b above.)
The source code for a work me ans the preferre d form of the work for ma king modicatio ns to it. For an
executable work , complete source code m eans all the source code f or all modules it cont ains, plus any
associated inter face denition le s, plus the script s used to control compi lation and instal lation of the
executable. Howeve r, as a special exception, t he source code distr ibuted need not in clude anything th at is
normally distri buted (in eithe r source or binary fo rm) with the major comp onents (compiler, kerne l, and so
on) of the operating sys tem on which the execu table runs, unl ess that component i tself accompanies t he
executable.
If distribution of e xecutable or obje ct code is made by offer ing access to copy from a des ignated place, the n
offering equival ent access to copy the sour ce code from the same pla ce counts as distr ibution of the sour ce
code, even though thir d parties are not co mpelled to copy the sour ce along with the obj ect code.
4. You may not copy, modify, sub license, or distr ibute the Progr am except as expres sly provided unde r this
License. Any attemp t otherwise to copy, mod ify, sublicense or dis tribute the Pro gram is void, and wil l
automatically ter minate your right s under this License . However, parties w ho have received copies , or rights,
from you under this Lice nse will not have their lic enses terminate d so long as such par ties remain in full
compliance.
5. You are not required to accept this L icense, since you have not sig ned it. However, nothing els e grants you
permission to modif y or distribute th e Program or its de rivative work s. These actions ar e prohibited by law if
you do not accept this License . Therefore, by modi fying or distr ibuting the Progr am (or any work based on the
Program), you indicate your a cceptance of this Licens e to do so, and all its terms a nd conditions for copying ,
distributing or mo difying the Progr am or works based o n it.
6. Each time you redistr ibute the Progr am (or any work based on th e Program), the recipi ent automatical ly
receives a license from t he original licens or to copy, distribute o r modify the Progr am subject to the se terms
and conditions. You may not impo se any further r estrictions o n the recipients’ e xercise of the right s granted
herein. You are not respon sible for enforcing com pliance by third par ties to this Licens e.
7. If, as a conseque nce of a court judgme nt or allegation of pa tent infringeme nt or for any other reas on (not
limited to patent issue s), conditions are impos ed on you (whether by cour t order, agreeme nt or otherwise)
that contradict th e conditions of this Li cense, they do not excuse y ou from the conditio ns of this License.
If you cannot distrib ute so as to satisf y simultaneous ly your obligations u nder this License an d any other
pertinent oblig ations, then as a co nsequence you may not dis tribute the Pro gram at all. For exa mple, if a
patent license would not pe rmit royalty- free redistr ibution of the Prog ram by all those who re ceive copies
directly or indir ectly through you , then the only way you cou ld satisfy both it a nd this License would b e to
refrain entirel y from distribu tion of the Progra m.
If any portion of this se ction is held inval id or unenforceable u nder any partic ular circumstan ce, the balance
of the section is intend ed to apply and the sec tion as a whole is int ended to apply in othe r circumstances .
It is not the purpose of thi s section to induce you t o infringe any patent s or other proper ty right claims o r
to contest validity of a ny such claims; this sec tion has the sole pu rpose of protect ing the integrit y of the
free software di stribution s ystem, which is im plemented by public l icense practice s. Many people have
made generous contr ibutions to the wide r ange of softwa re distribute d through that sys tem in reliance
on consistent applic ation of that syste m; it is up to the author /donor to decide if he or sh e is willing to
distribute sof tware through a ny other system an d a licensee cannot impo se that choice.
