P reamble
T he lic ens es for mos t s oftware are des igned to take away your freedom to s hare and c hange it. By c ontras t, the G N U G eneral
P ublic L ic ens e is intended to guarantee your freedom to s hare and c hange free s oftware- - to make s ure the s oftware
is free for all its us ers . T his G eneral P ublic L ic ens e applies to mos t of the Free Software Foundation's s oftware and to any
other program whos e authors c ommit to us ing it. (Some other Free Software Foundation s oftware is c overed by the G N U
L es s er G eneral P ublic L ic ens e ins tead.) Y ou c an apply it to your programs , too.
When we s peak of free s oftware, we are referring to freedom, not pric e. O ur G eneral P ublic L ic ens es are des igned to make
s ure that you have the freedom to dis tribute c opies of free s oftware (and c harge for this s ervic e if you wis h), that you rec eive
s ourc e c ode or c an get it if you want it, that you c an c hange the s oftware or us e piec es of it in new free programs ; and that
you know you c an do thes e things .
T o protec t your rights , we need to make res tric tions that forbid anyone to deny you thes e rights or to as k you to s urrender
the rights . T hes e res tric tions trans late to c ertain res pons ibilities for you if you dis tribute c opies of the s oftware, or if you
modify it.
For example, if you dis tribute c opies of s uc h a program, whether gratis or for a fee, you mus t give the rec ipients all the
rights that you have. Y ou mus t make s ure that they, too, rec eive or c an get the s ourc e c ode. A nd you mus t s how them thes e
terms s o they know their rights .
We protec t your rights with two s teps : (1 ) c opyright the s oftware, and (2 ) offer you this lic ens e whic h gives you legal permis s ion
to c opy, dis tribute and/or modify the s oftware.
A ls o, for eac h author's protec tion and ours , we want to make c ertain that everyone unders tands that there is no warranty
for this free s oftware. I f the s oftware is modified by s omeone els e and pas s ed on, we want its rec ipients to know that what
they have is not the original, s o that any problems introduc ed by others will not reflec t on the original
authors ' reputations .
Finally, any free program is threatened c ons tantly by s oftware patents . We wis h to avoid the danger that redis tributors of
a free program will individually obtain patent lic ens es , in effec t making the program proprietary. T o prevent his , we have
made it c lear that any patent mus t be lic ens ed for everyone's free us e or not lic ens ed at all.
T he prec is e terms and c onditions for c opying, dis tribution and modific ation follow.

0 . T his L ic ens e applies to any program or other work whic h c ontains a notic e plac ed by the c opyright holder s aying it may be
dis tributed under the terms of this G eneral P ublic L ic ens e. T he "P rogram", below, refers to any s uc h program or work, and a
"work bas ed on the P rogram" means either the P rogram or any derivative work under c opyright law:
that is to s ay, a work c ontaining the P rogram or a portion of it, either verbatim or with modific ations and/or trans lated
into another language. (H ereinafter, trans lation is inc luded without limitation in the term "modific ation".) E ac h lic ens ee is
addres s ed as "you".
A c tivities other than c opying, dis tribution and modific ation are not c overed by this L ic ens e; they are outs ide its s c ope.
T he ac t of running the P rogram is not res tric ted, and the output from the P rogram is c overed only if its c ontents c ons titute
a work bas ed on the P rogram (independent of having been made by running the P rogram). Whether that is true
depends on what the P rogram does .
1 . Y ou may c opy and dis tribute verbatim c opies of the P rogram's s ourc e c ode as you rec eive it, in any medium, provided
that you c ons pic uous ly and appropriately publis h on eac h c opy an appropriate c opyright notic e and dis c laimer of warranty;
keep intac t all the notic es that refer to this L ic ens e and to the abs enc e of any warranty; and give any other rec ipients of the
P rogram a c opy of this L ic ens e along with the P rogram.
Y ou may c harge a fee for the phys ic al ac t of trans ferring a c opy, and you may at your option offer warranty protec tion in
exc hange for a fee.
2 . Y ou may modify your c opy or c opies of the P rogram or any portion of it, thus forming a work bas ed on the P rogram, and
c opy and dis tribute s uc h modific ations or work under the terms of Sec tion 1 above, provided that you als o meet all of thes e
c onditions :
