GNU GENERAL PUBLIC LICENSE
Version 2, June 1991
Copyright (C) 198 9, 1991 Free Software Foundat ion, Inc., 51 Franklin
Street, Fifth Floor, Boston, MA 02110-1301 U SA Everyone is permitted to
copy and distr ibute verbatim copies of th is license document, but
changing it is not allowed.
Preamble
The licenses for most software are designed to take away your freedom
to share and c hange it. By contr ast, the GNU Ge neral Public Lice nse is
intended to guarant ee your freedom to share and chan ge free software--
to make sure the software is free for all its users. This General Public
License applies to mos t of the Free Software Foundation 's software and
to any other program whose authors c ommit to using it. (Some other Free
Software Fou ndation softw are is cove red by the G NU Lesser G eneral
Public License instead.) You can apply it to your programs, too.
When we speak of free soft ware, we are referring to freedom, no t price.
Our General P ublic Licenses are designed to make sure that you have th e
freedom to distr ibute copies of free software (an d charge for this service
if you wish ), that you rec eive source code or can ge t it if you want it, that
you can cha nge the soft ware or use pi eces of it in ne w free progr ams; and
that you know yo u can do these things.
To protect your rights, we need to make restrictions that forbid anyon e to
deny you these righ ts or to ask you to surrender the rights. These
restrictions translate to certain responsibilities for you if you distribute
copies of the software, or if you modify it.
For example, if you distribute copies of such a progr am, whether gratis or
for a fee, yo u must give the rec ipients all the rights that you have. Y ou
must make sure t hat they, too, receive or can get the source code. And
you must show the m these terms so th ey know their rights.
We protect you r rights with two steps: (1) co pyright the soft ware, and (2)
offer you this license which gives you legal permission to copy, distribute
and/or modify the software.
Also, for each author's protection and ours, we want to make c ertain that
everyone under stands that there is n o warr anty for this f ree software . If
the software is mod ified by someone else and passed on , we want its
recipients to know th at what they have is not the original, so that any
problems introduced by others will not reflect on the original authors'
reputations.
Finally, any free program is threatened constantly by sof tware patents.
We wish to avoid the danger that redistributors of a free program will
individually obtain patent licenses, in effect making the program
proprietary. To prevent this, we have made it clear that any patent must
be licen sed for ever yone's fre e use or no t licensed a t all.
The precise terms an d conditions for copying, distri bution and
modi ficatio n follow .
GNU GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND
MODIF ICATION
0. Th is License applies to any program or other work which contains a
notice placed by the copyright ho lder saying it may be distributed
under the terms of this General Public License. The "Program", below,
refers to any such program or work, an d a "work based on the
Program" m eans either the Program or any derivative work under
copyright law: that is to say, a work containing the Program or a
portion of it, e ither verbatim or with modifications an d/or translated
into another language. (Hereinafter, translation is included without
limitation in the term " modification".) Each licensee is addresse d as
"you".
Activities ot her than copying, distribution and modification are not
covered by th is License; they are outside its scope. The ac t of running
the Program is n ot restricted, and th e output from th e Program is
covered only if its co ntents constitute a work base d on the Program
(independent of having been made by running the Program).
Whether that is tr ue depends on what the Program does.
1. You may copy and distribute verbatim c opies of the Program's source
code as you receive it, in any medium, provided that you
conspicuously and appr opriately publish on each copy an
appropriate copy right 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 offe r warranty protection in exc hange for a fee.
2. You m ay modify your copy or copie s of the Program or any port ion of
it, thus forming a work based on the Program, and co py and
distribute such modifications or work under th e terms of Section 1
above, provided that you also meet all of these conditions:
a) You must cause the modified files to car ry prominent notices
stating that you changed the files and the date of any change.
b) You mu st cause an y work that yo u distribute or publish, that in
whole or in part cont ains or is derived from the Program or any
part thereof, to be licensed as a whole at no charge to all thir d
parties unde r the terms o f this License .
c) If the modified program normally reads comman ds interactively
when run, y ou must c ause it, when started ru nning for such
interactive u se in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a
notice that there is no war ranty (or else, saying that you provide a
warranty) and that us ers may redistribute the p rogram under
these conditions, and telling the user how to v iew a copy of this
License. (Exception: if the Program itself is interactive but does
not normally pr int such an announ cement, your work based on
the Program is not require d to print an announceme nt.)
These requireme nts apply to the modifie d work as a whole. If ide ntifiable
sections of that work are not derived fro m the Program, and can be
reasonably consider ed independent and separate works in them selves,
then this License, and its te rms, do not apply to those sec tions 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
distributi on of the whole must be on the terms of this Li cense, whose
permissions for ot her licensees extend to the en tire whole, and thus to
each and ever y part regard less of who wrote it.
Thus, it is not the intent of this section to claim rights or contest your
rights to work writ ten entirely by yo u; rather, the intent is to exercise the
right to control the distribution of der ivative or collective works based on
the Progra m.
In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution mediu m does not bring the other work under the
scope of this License .
3. You may copy and distribute the Prog ram (or a work based on it,
under S ection 2) in object cod e or execut able form u nder the term s of
Sections 1 and 2 abov e provided that you also do one of the following:
a) Accompany it with th e complete correspondi ng machine-
readable source code, whic h must be distributed under the terms
of Sections 1 and 2 above on a medium customarily used for
software in terchange; o r,
b) Accompany it with a written offer, valid for at least three years, to
give any third party, for a charge no more than your cost of
physically perf orming source distributi on, a complete machine-
readable copy of the corres ponding source code, to be distributed
under the terms of Sect ions 1 and 2 above on a medium
customarily used for software interchange; or,
c) Accompany it with the information you receiv ed as to the offer to
distribute correspon ding source code. (This alternative is allowed
only for noncommercial distribution and only if you received the
program in object cod e or executable form with such an offer, in
accord with Subsec tion b above.)
The source code fo r a work means the preferred fo rm of the work for
making modifications to it. For an executable work, complete sourc e
code means all the source code fo r all modules it contains, plus any
associat ed interface d efinition file s, plus the scrip ts used to contro l
compilation and installation of th e executable. However, as a special
exception, the source code distr ibuted need not include a nything that is
normally distributed (in either sourc e or binary form) with the major
components (com piler, kernel, and so on) of the operat ing system on
which the executable runs, unless that component itself accompanies
the executa ble.
If distribution of ex ecutable or object code is made by offering access to
copy from a designated place, then of fering equivalent acc ess to copy the
source code f rom the same place co unts as distribution of the so urce
code, even thou gh third parties are no t compelled to copy th e source
along with the object code.
4. You may not copy, m odify, sublicense, or distribute the Program
except as expressly pr ovided under this License. Any att empt
otherwise to copy, mod ify, sublicense or distribute t he Program is
void, and will automatically terminate your rig hts under this Lice nse.
However, parties who have received copies, or rights, fro m you under
this License will not have their licenses terminated so long as such
