The precise terms and condit ions for copying, distri bution and modification follow.
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to an y program or other work which contains a notice placed by the copyright holder
saying it may be dist ributed under the terms of this Genera l Public License. The “Program”, below, r efers to
any such program or work, and a “ work based on the Program” means eithe r the Program or any derivati ve
work under copyrig ht law: that is to s ay, a work containing the Program or a portion of it, either ver batim or
with modifications and/ or translated into anot her language. (Hereinaf ter, translation i s included without
limitation in the ter m “modification”.) Each li censee is addressed as “you”.
Activities other than copying, distribu tion and modification are not covered by thi s License; they are out side
its scope. The ac t of running the Progr am is not restrict ed, and the output from the Program is covere d only
if its contents consti tute a work based on the Program (in dependent of having been made by running the
Program). Whether that is tru e depends on what the Program does.
1. You may copy and distribute verbatim copi es of the Program’s source code as you receive i t, in any medium,
provided that you cons picuously and appropriat ely publish on each copy an a ppropriate copyright notice and
disclaimer of warranty; k eep intact all the noti ces that refer to this Licen se and to the absence of any
warranty; and give any other rec ipients of the Program a copy of thi s License along with the Program.
You may charge a fee for t he physical act of tr ansferring a copy, a nd you may at your option off er warranty
protection in exch ange for a fee.
2. You may modify your copy or copies of the Program or any portion of it , thus forming a work based on the
Program, and copy and distribute such modifi cations or work under the terms of Section 1 above, provi ded
that you also meet all of these conditions:
a) You must cause the modified fil es to carry prominent notices stating that you changed the files and the
date of any change.
b) You must cause any work that you distri bute or publish, that in whole or in par t contains or is derived fr om
the Program or any part thereof, to be licensed a s a whole at no charge to al l third parties under t he terms
of this License.
c) If the modified program normally reads commands i nteractively when run, you must cause i t, when started
running for such int eractive use in the most or dinary way, to print or display an announcement i ncluding
an appropriate copyright not ice and a notice that there is no warranty (or el se, saying that you provide a
warranty) and that user s may redistribute the progr am under these conditions, and telling the user how to
view a copy of this Licens e. (Exception: if the Program itself is interac tive but does not normally print such
an announcement, your work based on the Pr ogram is not required to pri nt an announcement.)
These requirements appl y to the modified work as a whol e. If identifiabl e sections of that work are not derived
from the Program, and can be reasonabl y considered independent and separ ate works in themselves, then
this License, and its ter ms, do not apply to those sections when you distri bute them as separate works. But
when you distribute the same se ctions as part of a whole which is a work based on the Progr am, the
distribution of the whole mu st be on the terms of this License, whose permissions for other licensees extend
to the entire whole, and thus to each and every part r egardless of who wrote it.
Thus, it is not the in tent of this section t o claim rights or contest your rights to work written e ntirely by you;
rather, the i ntent is to exerci se the right to control the dis tribution of deri vative or collect ive works based on
the Program.
In addition, mere aggr egation of another work not bas ed on the Program with the Program (or with a work
based on the Program) on a volume of a stor age or distribution medium does not bri ng the other work under
the scope of this License.
3. You may copy and distribute the Program (or a work based on it, under Sect ion 2) in object code or
executable form und er the terms of Sections 1 and 2 above prov ided that you also do one of t he following:
a) Accompany it with the complete correspondi ng machine-readable source code, which must be distributed
under the terms of Secti ons 1 and 2 above on a medium customarily us ed for software interchange ; or,
b) Accompany it with a writ ten offer, vali d for at least three years , to give any third part y, for a charge no
more than your cost of phys ically performing sour ce distribution, a comple te machine-readable copy of
the corresponding sourc e code, to be distributed under the ter ms of Sections 1 and 2 above on a medium
customarily used for software interchange; or ,
c) Accompany it with the i nformation you receive d as to the offer to distr ibute corresponding s ource code.
(This alternative is al lowed only for noncommercial distribution and only if you rec eived the program in
object code or executab le form with such an offer, in ac cord with Subsection b above .)
The source code for a wo rk means the preferred form of t he work for making modifications to i t. For an
executable work, compl ete source code means all the sourc e code for all modules it contains, plus any
associated inter face definition files, plus the scripts used to c ontrol compilation and in stallation of the
executable. However, as a spec ial exception, the sourc e code distributed need not incl ude anything that is
normally distr ibuted (in either source or binary form) with the majo r components (compiler, k ernel, and so on)
of the operating system on whi ch the executable runs, unless t hat component itself accompanies the
executable.
If distribution of executable or object code is made by offering ac cess to copy from a desig nated place, then
offering equivalent acc ess to copy the source code f rom the same place counts as distr ibution of the source
code, even though th ird parties are not compelled t o copy the source along wit h the object code.
4. You may not copy, modify, subli cense, or distribute the Program except as expressly pr ovided under this
License. Any attempt ot herwise to copy, modify , sublicense or distri bute the Program is void, and wi ll
automatically ter minate your rights under this Li cense. However, parties who have receive d copies, or rights,
from you under this License will not have their licenses terminated so lo ng as such parties remain i n full
compliance.
5. You are not required to ac cept this License, sinc e you have not signed it. However, n othing else grants you
permission to modify or di stribute the Program or its deriv ative works. These actions are prohib ited by law if
you do not accept this L icense. Therefore, by modifyi ng or distributing the Progr am (or any work based on
the Program), you indi cate your acceptance of thi s License to do so, and all its t erms and conditions for
copying, distribut ing or modifying the Pr ogram or works based on it.
6. Each time you redistribute t he Program (or any work based on t he Program), the recipient automat ically
receives a license from the ori ginal licensor to copy, dis tribute or modify the Program subjec t to these terms
and conditions. You may not i mpose any further restric tions on the recipients ’ exercise of the rights gr anted
herein.
You are not responsible for enforcing compliance by thi rd parties to this License .
7. If, as a consequence of a court j udgment or allegation of pat ent infringement or for any othe r reason (not
limited to patent i ssues), conditions are imposed on yo u (whether by court order, agr eement or otherwise)
that contradict the c onditions of this L icense, they do not excuse y ou from the conditions of this Li cense. If
you cannot distribute s o as to satisfy simultaneousl y your obligations under this License and any other
pertinent obli gations, then as a consequence you may not di stribute the Program at all. For example, if a
patent license woul d not permit royalty-free redi stribution of the Program by al l those who receive copies
directly or indirect ly through you, then the only way you could satisfy both it and thi s License would be to
refrain entirel y from distribution of the Program.
If any portion of this sect ion is held invalid or unenforceabl e under any particular circ umstance, the balance
of the section is intended to apply and the secti on as a whole is intended to appl y in other circumstances.
It is not the pur pose of this section to i nduce you to infringe any pa tents or other proper ty right claims or to
contest validity of any such claims; this sect ion has the sole purpose of prot ecting the integrit y of the free
software distribut ion system, which is implement ed by public license practic es. Many people have made
generous contributions to the wide range of softwar e distributed through that system in reliance on consist ent
application of t hat system; it is up to the aut hor/donor to decide if he or she i s willing to distribute sof tware
through any other system and a l icensee cannot impose that choice.
This section is int ended to make thoroughly clear what is believed to be a consequen ce of the rest of this
License.
8. If the distribution a nd/or use of the Program is rest ricted in certain cou ntries either by patents or by
copyrighted inter faces, the original copyri ght holder who places the Program under this License may add an
explicit geographi cal distribution l imitation excluding t hose countries, so that distribut ion is permitted only in
