However, parti es who have receive d copies, or r ights, fro m you
under this Lice nse will not have their licen ses termina ted so long as
such p arties r emain in full co mplian ce.
5. You are not required to accept this License, s ince you have not
sig ned it. Ho weve r, not hin g els e grant s you permiss ion to m odify or
distribu te the Program or its deriva tive works. These actions are
prohibite d by law if you do not accept t his License. Th erefore, by
modifying or distributi ng the Program (o r any work based on the
Program ), y ou indicate your acceptance of t his License to do so, and
all its terms an d conditions for copying, dist ributin g or modifyin g the
Program or wor ks based on it.
6. Each time you redistr ibute the Pro gram (or any wor k based on the
Program), th e recipient auto matically r eceives a licen se from the
original lice nsor to copy, d istribute or modify the Program subject to
these terms a nd conditions. You may not impose any further
restricti ons on the rec ipients' exer cise of the ri ghts granted
herein.You a re not responsible for enfor cing compliance by third
parties to this License.
7. If, as a consequence of a court ju dgment or alle gation of paten t
infringement or for any oth er reason (no t limited to p atent issues),
conditions a re imposed on you (whether by court order , agreement
or otherwise ) that contra dict the condi tions of this License, they d o
not excuse yo u from the condit ions of thi s License. If you cannot
distribute so as to sa tisfy simulta neously your obligatio ns under this
License and any other pertinen t obliga tions, then as a consequence
you may not d istribute the P rogram at al l. For example, i f a patent
license would not perm it royalty- free redistrib ution of t he Program b y
all those who receive copie s directly o r indirectly through you, the n
the only wa y you could satisfy both it a nd this License would be to
refrain entirely from dis tributio n of t he Prog ram.
If any po rtion of thi s section is h eld invalid or unenforceabl e und er
any parti cular circumstance, the balance o f the section i s intend ed
to apply a nd the section as a whole is intended to appl y in other
circumstances.
It is not the purpose of t his sect ion to induce you to infrin ge any
patents or other property r ight clai ms or to contest va lidity of a ny
such claims; this secti on has the sol e purpose of protecti ng the
integrity o f the free so ftware distri bution syste m, which is
implemented by p ublic license practices. Ma ny people have made
generous contr ibutions to t he wide range of software dist ributed
through tha t system in reli ance on consi stent applicati on of that
system; it is up to t he author/donor to decide if he or she i s willing to
distribute so ftware through any oth er system and a licensee cannot
impose that choice.
Thi s section is int ended to m ake thorough ly clear w ha t is bel ieved to
be a consequenc e of the rest o f this Li cense.
8. If the distrib ution and/or u se of the Prog ram is restri cted in certain
countries either by patents or b y copyri ghted i nterfaces, the orig ina l
copyright holder who places th e Program under this License ma y
add an explic it geogra phical distribu tion lim itation excluding thos e
countries, so that distributio n is permitted only in or among countri es
not thus excluded. In such case, this Li cense incorporate s the
limitation as if wri tten in the bod y of this L icense.
9. The Fr ee Soft ware F oundat ion may publish revised and/ or new
versions of th e General Public License from time to time. Such ne w
versions will be sim ilar in spirit to th e pre se nt ver si on, bu t ma y diff er
in detail to address new proble ms or concerns.
Each version is g iven a disti nguishing vers ion number. If th e
Program specifie s a version number of this License which a pplies to
it and "any late r version", you have the optio n of following the te rms
and condition s either of that version or o f any later version published
by the Free Software Foundatio n. If the Program do es not specify a
version number of t his License, yo u may choose any version ever
publis hed b y the F ree Soft ware F oundat ion.
10. If you wish to incorpo rate parts of the Program int o other fre e
progr ams w ho se di str ibut ion con diti ons are dif fer ent, wr ite to the
author to ask fo r permission. Fo r software wh ich is copyri ghted by
the Free Software Foundation, wri te to the Fr ee Software
Foundation; we someti mes make exceptio ns for this. Our decision
will be gui ded by the two goal s of preservin g the free sta tus of all
derivatives o f our free sof tware and of pro moting the sharin g and
reuse of sof twar e ge ner all y.

How to Apply These Terms to Your New Programs
If you de velop a new program, and you want i t to be of the greatest
possible use to the public, the best way to achieve this is to make it free
software whi ch everyone can re distribute a nd change under these
term s
To do so, attach the fol lowing notic es to the program. I t is safe st to
attach them to the start of each source file to most effecti vely convey t he
exclusion of warr anty; and each file sh ould have a t least the "copyri ght"
line an d a pointer to where the ful l notice is fo und.
