Everyone is permitted to copy and distribute verbatim copies of this
license
document,
but
changing
it
is
not
allowed.
Preamble
The
GNU
General
Public
License
is
free,
copyleft
license
for
software
and
other
kinds
of
works.
The
licenses
for
most
software
and
other
practical
works
are designed to take away your freedom to share and change the works.
By
contrast, the GNU General Public License is intended to guarantee your
freedom
to
share
and
change
all
versions
of
program--to
make
sure
it
remains
free
software
for
all
its
users.
We, the Free Software Foundation, use the
GNU General Public License for most of our software; it applies also to
any other work released this way by its authors.
You can apply it to your
programs,
too.
When
we
speak
of
free
software,
we are referring to freedom, not price.
Our General Public Licenses are designed to
make
sure
that you have the freedom to distribute copies of free software (and charge for
them
if you wish), that you receive source code or can get it if you want it, that you can change the software or
use
pieces
of
it
in
new
free
programs,
and that you know you can do these things.
To
protect
your
rights,
we need to prevent others from denying you these rights or asking you to surrender the rights.
Therefore, you have certain responsibilities
if
you
distribute
copies
of
the
software,
or
if
you
modify
it:
responsibilities
to
respect
the freedom of others.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must pass on to the recipients the same
freedoms that you received.
You must make sure that they, too, receive
or can get the source code.
And you must show them these terms so they
know their rights.
Developers that use the GNU GPL protect your rights with two steps: (1) assert
on
the software, and (2) offer you this License giving you legal permission to copy, distribute and/or modify it.
For the
developers'
and
authors'
protection, the GPL
clearly
explains that there is no warranty for this free software.
For both
users'
and
authors'
sake,
the GPL requires that modified versions be marked as changed, so that
their problems will not be attributed erroneously to authors of previous
versions.
Some
devices
are
designed
to
deny
users
access
to
install
or
run
modified
versions
of
the
software
inside
them,
although
the
manufacturer
can
do
so.
This
is
fundamentally
incompatible
with
the
aim
of
protecting
users'
freedom
to
change
the
software.
The
systematic
pattern
of
such
abuse
occurs
in
the
area
of
products
for
individuals
to
use,
which is precisely where it is most unacceptable.
Therefore, we have designed this version of the GPL to
prohibit
the
practice
for
those
products.
If such problems arise substantially in other domains, we
stand
ready to extend this provision to those domains in future versions of the GPL, as needed to protect the freedom of users.
Finally,
every
program
is
threatened
constantly
by
software
patents.
States
should
not
allow
patents
to
restrict
development
and
use
of
software
on
general-purpose
computers,
but
in those that do, we wish to avoid the special danger that patents
applied to a free program could make it effectively proprietary.
To
prevent
this,
the
GPL
assures that patents cannot be used to render the program non-free.
The precise terms and conditions for
copying,
distribution
and
modification
follow.
TERMS AND CONDITIONS
0.
Definitions.
"This License" refers to version 3 of the GNU General Public
License.
"Copyright" also means copyright-like laws that apply to other
kinds of works, such as semiconductor masks.
"The
Program"
refers to any copyrightable work licensed under this License.
Each licensee is addressed as "you."
"Licensees" and
"recipients" may be individuals or organizations.
To
"modify"
work
means
to
copy
from
or
adapt
all
or
part
of
the
work
in
fashion
requiring
permission,
other than the making of
an
exact
copy.
The
resulting
work
is
called
"modified
version"
of
the
earlier
work
or
work
"based
on"
the
earlier
work.
A "covered work"
means either the unmodified Program or a work based on the Program.
To
"propagate"
work
means
to
do
anything
with
it
that,
without
permission,
would
make
you
directly
or
secondarily
liable
for
infringement
under
applicable
law,
except executing it on a computer or making modifications that you do not share.
Propagation includes copying, distribution (with or without modification), making available to the public, and in some
countries
other activities as well.
To "convey" a work means
any
kind
of
propagation
that
enables
other
parties
to
make
or
receive
copies,
excluding sublicensing.
Mere
interaction with a user through a computer network, with no transfer
of a copy, is not conveying.
An interactive user interface
displays
"Appropriate
Legal
Notices"
to
the extent that it includes a convenient and prominently visible
feature that (1) displays an appropriate copyright notice, and (2) tells
the user that there is no warranty for the work (except to the extent
that warranties are provided), that licensees may convey the work under
this License, and how to view a copy of this License.
If
the interface presents a list of user commands or options, such as a
menu, a prominent item in the list meets this criterion.
1.
Source
Code.
The
"source
code"
for
work
means
the
preferred
form
of
the
work
for
making
modifications
to
it.
"Object code" means any non-source
form of a work.
A "Standard Interface" means an interface that either is an official standard defined by
recognized
standards
body,
or,
in the case of interfaces specified for a particular programming
language, one that is widely used among developers working in that
language.
The
"System
Libraries"
of
an
executable
work
include
anything,
other
than
the work as a whole, that
(a)
is
included
in
the
normal
form
of
packaging
Major
Component,
but
which
is
not
part
of
that
Major
Component,
and
(b)
serves
only
to
enable
use
of
the
work
with
that
Major
Component,
or
to
implement
Standard
Interface
for
which
an
implementation
is
available to the public in source code form.
"Major Component", in this context, means a major essential component
(kernel, window system, and so on) of the specific operating system (if
any) on which the executable work runs, or a compiler used to produce
the work, or an object code interpreter used to run it.
The "Corresponding Source" for a work in object code form means all
the source code needed to generate, install, and (for an executable
work) run the object code and to modify the work, including scripts to
control those activities.
However, it does not include the work's System Libraries, or general-purpose tools or generally available free programs
which
are
used
unmodified
in
performing
those
activities
but
which
are
not
part
of
the
work.
For example, Corresponding Source includes interface definition files associated with
source
files
for
the work, and the source code for shared libraries and dynamically
linked subprograms that the work is specifically designed to require,
such as by intimate data communication or control flow between those
subprograms and other parts of the work.
The Corresponding Source
need
not
include
anything
that
users
can
regenerate
automatically
from
other
parts
of
the
Corresponding
Source.
The Corresponding Source for a work in source code form is that
same work.
2. Basic Permissions.
All rights granted under this License are granted for the term of
copyright on the Program, and are irrevocable provided the stated
conditions are met.
This License explicitly affirms your
unlimited
permission
to
run
the
unmodified
Program.
The output from running a
covered work is covered by this License only if the output, given its
content, constitutes a covered work.
This
License
acknowledges
your
rights
of
fair
use
or
other
equivalent,
as
provided
by
law.
You may make,
run
and
propagate
covered
works
that
you
do
not
convey,
without
conditions
so long as your license otherwise remains in force.
You
may
convey
covered
works
to
others
for
the
sole
purpose
of
having
them
make
modifications
exclusively
for
you,
or
provide
you
with
facilities
for
running
those
works,
provided that you comply with the terms of this License in conveying all material for which you do not hold copyright.
Those
thus
making
or
running
the
covered
works
for
you
must
do
so
exclusively
on
your
behalf,
under
your
direction
and
control,
on
that
prohibit
them
from
making
any
copies
of
your
copyrighted
material
outside
their
relationship
with
you.
Conveying under any other circumstances is permitted solely under
the conditions stated below.
Sublicensing is not allowed; section 10
makes it unnecessary.
3.
Protecting
Users'
Legal
Rights
From
Anti-Circumvention
Law.
No
covered
work
shall
be
deemed
part
of
an
effective
technological
measure
under
any
applicable
law
fulfilling
obligations
under
article
11
of
the
WIPO
treaty
adopted
on
20
December
1996,
or
similar
laws
prohibiting
or
restricting
circumvention
of such measures.
When you convey a covered work,
you
waive
any
legal
power
to
forbid
circumvention
of
technical
measures
to
the
extent
such
circumvention
is
effected
by
exercising
rights
under
this
License
with
respect
to
the
covered
work,
and
you
disclaim
any
intention
to
limit
operation
or
modification
of
the
work
as
means
of
enforcing,
against
the
work's
users,
your
or
third
parties'
legal
rights
to
forbid
circumvention
of
technical
measures.
4.[1]
Conveying
Verbatim
Copies.
You
may convey verbatim copies of the Program's source code as you receive
it, in any medium, provided that you conspicuously and appropriately
publish on each copy an appropriate copyright notice;
keep
intact
all
notices
stating
that
this
License
and
any non-permissive terms added in accord with section 7 apply to the
code; keep intact all notices of the absence of any warranty; and
give
all
recipients
copy
of
this
License
along
with
the
Program.
You may charge any price or no price for each copy that you convey,
and you may offer support or warranty protection for a fee.
5.[2] Conveying Modified Source Versions.
You
may
convey
work
based
on
the
Program,
or
the
modifications
to
produce
it
from
the
Program,
in the form of source code
under
the
of
section
above,
provided that you also meet all of these conditions:
a) The work must carry prominent notices stating that
you
modified it, and
giving
relevant
date.
b)
The
work
must
carry
prominent
notices
stating
that
it
is
released
under
this
License
and
any
conditions
added
under
section
7.
This requirement modifies the requirement in section 4 to
"keep intact all notices".
c) You must
license
the
entire
work,
as
whole,
under this License to anyone who comes into possession of a copy.
This
License will therefore apply, along with any applicable section 7
additional terms, to the whole of the work, and all its parts,
regardless of how they are packaged.
This License gives no permission to license the work in any other way, but
it
does
not
invalidate
such
permission
if
you
have
separately
received
it.
d)
If
the
work
has
interactive
user
interfaces,
each
must
display
Appropriate
Legal
Notices;
however,
if
the
Program
has
interactive
interfaces
that
do
not
display
Appropriate
Legal
Notices,
your
work
need
not
make
them
do
so.
A compilation of a covered work with other separate and independent works, which are not by their nature
extensions
of
the
covered
work,
in
or on a volume of a storage or distribution medium, is called an
"aggregate" if the compilation and its resulting copyright are not used
to limit the access or legal rights of the compilation's users beyond
what the individual works permit.
Inclusion
of
covered
work
in
an
aggregate
does
not
cause
this
License
to
apply
to
the
other
parts
of
the
aggregate.
6.[3]
Conveying
Non-Source
Forms.
You may convey a covered work in object code form under the terms of sections 4 and 5, provided that you also convey
the
machine-readable
Corresponding
Source
under the terms of this License, in one of these ways:
a) Convey the object code in, or embodied in, a physical product
(including a physical distribution medium), accompanied by the
Corresponding Source fixed on a durable physical medium
customarily used for software interchange.
b)
Convey the object code in, or embodied in, a physical product
(including a physical distribution medium), accompanied by a written
offer, valid for at least three years and valid for as long as you offer
spare parts or customer support for that product model, either (1) to
give anyone who possesses the object code a copy of the Corresponding
Source for all the software in the product that is covered by this
License, on a durable physical medium customarily used for software
interchange, for a price no more than your reasonable cost of physically
performing this conveying of source, or (2) to provide access to copy
the Corresponding Source from a network server at no charge.
c) Convey individual copies of the object code with a copy of the
written offer to provide the Corresponding Source.
This
alternative is allowed only occasionally and noncommercially, and only
if you received the object code with such an offer, in accord with
subsection 6b.
d) Convey the object code by offering access from a designated
place (gratis or for a charge), and offer equivalent access to the
Corresponding Source in the same way through the same place at no
further charge.
You need not require recipients to copy the
Corresponding Source along with the object code.
If
the place to copy the object code is a network server, the
Corresponding Source may be on a different server (operated by you or a
third party) that supports equivalent copying facilities, provided you
maintain clear directions next to the object code saying where to find
the Corresponding Source.
Regardless
of
what
server
hosts
the
Corresponding
Source,
you
remain
obligated
to
ensure
that
it
is
available
for
as
long
as
needed
to
satisfy
these
requirements.
e)
Convey
the
object
code
using
peer-to-peer
transmission,
provided
you
inform
other
peers
where
the
object
code
and
Corresponding
Source
of
the
work
are
being
offered
to
the
general
public
at
no
charge
under
subsection
6d.
separable
portion
of
the
object
code,
whose
source
code
is
excluded
from
the
Corresponding
Source
as
System
Library,
need
not
be
included
in
conveying
the
object
code
work.
"User
Product"
is
either
(1) a "consumer product,"
which
means
any
tangible
personal
property
which
is
normally
used
for
personal,
family,
or
household
purposes,
or (2) anything designed or sold for incorporation into a dwelling.
In determining whether a product is a consumer product, doubtful cases shall be resolved
in
favor
of
coverage.
For a particular product received by a particular user,
"normally
used"
refers
to
typical
or
common
use
of
that
class
of
product,
regardless
of the status of the particular user or of the way in which the
particular user actually uses, or expects or is expected to use, the
product.
A product is a consumer product regardless of whether the product has substantial commercial,
industrial
or
non-consumer
uses, unless such uses represent the only significant mode of use of the product.
"Installation
Information"
for
User
Product
means
any
methods,
procedures,
authorization
keys,
or
other
information
required
to
install
and
execute
modified
versions
of
covered
work
in that User Product from a modified version of its Corresponding Source.
The information must suffice to ensure that the continued functioning of the modified
object
code
is in no case prevented or interfered with solely because modification has been made.
If
you
convey
an
object
code
work
under
this
section
in,
or
with,
or
specifically
for
use
in,
User
Product,
and
the
conveying
occurs
as
part
of
transaction
in
which
the
right
of
possession
and
use
of
the
User
Product
is
transferred
to
the
recipient
in
perpetuity
or for a fixed term (regardless of how the transaction is
characterized), the Corresponding Source conveyed under this section
must
be
accompanied
by
the Installation Information.
But
this
requirement
does
not
apply
if
neither
you
nor
any
third
party
retains
the
ability
to
install
modified
object
code
on the User Product
(for
example,
the
work
has
been
installed
in
ROM).
The
requirement
to
provide
Installation
Information
does
not
include
requirement
to
continue
to
provide
support
service,
warranty,
or
updates
for
work
that
has
been
modified
or
installed
by
the
recipient,
or for the User Product in which it has been modified or installed.
Network
access
may
be
denied
when the modification itself materially and adversely affects the operation of the
network
or
violates
the
rules
and
protocols
for
communication
across
the
network.
Corresponding Source conveyed, and Installation Information provided,
in accord with this section must be in a format that is publicly
documented (and with an implementation available to the public in
source code form), and must require no special password or key for
unpacking, reading or copying.
7.
Additional
Terms.
"Additional permissions" are terms that supplement the terms of this
License by making exceptions from one or more of its conditions.
Additional
permissions
that
are
applicable
to
the
entire
Program
shall
be
treated
as
though
they
were
included
in
this
License,
to the extent that they are valid under applicable law.
If additional permissions
apply only to part of the Program, that part may be used separately
under those permissions, but the entire Program remains governed by
this License without regard to the additional permissions.
When you convey a copy of a covered work, you may at your option
remove any additional permissions from that copy, or from any part of
it.
(Additional permissions may be written to require their own
removal in certain cases when you modify the work.)
You may place
additional permissions on material, added by you to a covered work,
for which you have or can give appropriate copyright permission.
Notwithstanding
any
other
provision
of
this
License,
for
material
you
add
to
covered
work,
you
may
(if
authorized
by
the
holders
of
that
material)
supplement
the
of
this
License
with
terms:
a. disclaiming warranty or limiting liability differently from the
terms of sections 15 and 16 of this License; or
b.
requiring
preservation
of
specified
reasonable
legal
notices
or
author
attributions
in
that
material
or
in
the
Appropriate
Legal
Notices
displayed
by
works
containing
it;
or
c.
prohibiting
misrepresentation of the origin of that material, or requiring that
modified versions of such material be marked in reasonable ways as
different from the original version; or
d. limiting the use for publicity purposes of names of licensors or
authors of the material; or
e.
declining
to
grant
rights
under
trademark
law
for
use
of
some
trade
names,
trademarks,
or
service
marks;
or
f.
requiring
indemnification
of
licensors
and
authors
of
that
material
by
anyone
who
conveys
the
material
(or
modified
versions
of
it)
with
contractual
assumptions
of
liability
to
the
recipient,
for
any
liability
that
these
contractual
assumptions
directly
impose on those licensors and authors.
All other non-permissive additional terms are considered "further
restrictions" within the meaning of section 10.
If
the
Program
as
you
received
it,
or
any
part
of
it,
purports
to
be
governed
by
this
License,
supplemented
by
term
that
is
further
restriction,
you
may
remove
that
term.
If a license document contains a further
restriction but permits relicensing or conveying under this License,
you may add to a covered work material governed by the terms of that
license document, provided that the further restriction does not
survive such relicensing or conveying.
If you add terms to a covered work in accord with this section, you
must place, in the relevant source files, a statement of the
additional terms that apply to those files, or a notice indicating
where to find the applicable terms.
Additional terms, permissive or non-permissive, may be stated in the
form of a separately written license, or stated as exceptions;
the above requirements apply either way.
8.[4]
Termination.
You may not propagate or modify a covered work except as expressly
provided under this License.
Any attempt otherwise to propagate or
modify it is void.
If
you violate this License, any copyright holder of the work may put you
on notice by notifying you of the violation, by any reasonable means,
provided
60
days
have
not
elapsed
since
the
most
recent
violation.
Having
put
you
on
notice,
the
holder
may,
at
any
time,
terminate
the
rights
(including any patent rights) that the copyright holder has granted to you under this License.
However,
if
this
is
the
first
time
you
have
received
notice
of
violation
of
this
License
(for
any
software)
with
respect
to
given
holder,
and
you
cure
the
violation
within
30
days
following
your
receipt
of
the
notice,
then
your
license
is
automatically
reinstated.
In the event that your rights are terminated under this section,
parties who have received copies, or rights, from you under this
License will not have their licenses terminated so long as they remain
in full compliance.
Unless and until your rights are restored by the
copyright holders, you do not qualify to receive licenses for the same
material under section 10.
9.[5]
Acceptance
Not
Required
for
Having
Copies.
You are not required to accept this License in order to receive or
run a copy of the Program.
Ancillary propagation of a covered work
occurring solely as a consequence of using peer-to-peer transmission
to receive a copy likewise does not require acceptance.
However, nothing other than this License grants you permission to propagate or
modify
any covered work.
These actions infringe copyright if you do
not accept this License.
Therefore, by modifying or propagating a
covered work, you indicate your acceptance of this License to do so.
10.[6] Automatic Licensing of Downstream Recipients.
Each time you convey a covered work, the recipient automatically
receives a license from the original licensors, to run, modify and
propagate that work, subject to this License.
You are not responsible
for enforcing compliance by third parties with this License.
An "entity transaction" is a transaction transferring control of an
organization, or substantially all assets of one, or subdividing an
organization, or merging organizations.
If
propagation of a covered work results from an entity transaction, each
party to that transaction who receives a copy of the work also receives
whatever licenses to the work the party's predecessor in interest had or
could give under the previous
paragraph,
plus
right
to
possession
of
the
Corresponding
Source
of
the
work
from
the
predecessor
in
interest,
if
the
predecessor
has
it
or
can
get
it
with
reasonable
efforts.
You
may
not
impose
any
further
restrictions
on
the
exercise
of
the
rights
granted
or
affirmed
under
this
License.
For
example, you may not impose a license fee, royalty, or other charge for
exercise of rights granted under this License, and you may not initiate
litigation (including a cross-claim or counterclaim in a lawsuit)
alleging that any patent claim is infringed by making, using, selling,
offering for sale, or importing the Program or any portion of it.
11.
Patents.
"contributor"
is
holder
who authorizes use under this License of the
Program
or a work on which the Program is based.
The
work thus licensed is called the contributor's "contributor version."
contributor's "essential patent claims" are all patent claims owned or
controlled by the contributor, whether already acquired
or
hereafter
acquired,
that
would be infringed by some manner, permitted by this License, of
making, using, or selling its contributor version, but do not include
claims that would be infringed only as a consequence of further
modification of the contributor version.
For
purposes of this definition, "control" includes the right to grant
patent sublicenses in a manner consistent with the requirements of
this License.
Each
contributor
grants
you
non-exclusive,
worldwide,
royalty-free
patent
license
under the contributor's essential patent claims,
to
make,
use,
sell,
offer
for
sale,
import
and
otherwise
run,
modify
and
propagate
the
contents
of
its
contributor
version.
For
purposes
of
the
following
three
paragraphs,
"patent license" is any express agreement or commitment, however
denominated, not to enforce a patent, and to "grant" a patent license to
a party means to make such an agreement or commitment not to enforce a
patent against the party.
If
you convey a covered work, knowingly relying on a patent license, and
the Corresponding Source of the work is not available for anyone to
copy, free of charge and under the terms of this License, through a
publicly available network server or other readily accessible means,
then you must either
(1)
cause
the
Corresponding
Source
to
be
so
available,
or
(2) disclaim the patent license for this particular work, or (3)
arrange, in a manner consistent with the requirements of this License,
to extend the patent license
to
downstream
recipients.
"Knowingly
relying" means you have actual knowledge that, but for the patent
license, your conveying the covered work in a country, or your
recipient's use of the covered work in a country, would infringe
one
or
more
identifiable
patents
in that country that you have reason to believe are valid.
If,
pursuant to or in connection with a single transaction or arrangement,
you convey, or propagate by procuring conveyance of, a covered work, and
grant a patent license to some of the parties receiving the covered
work authorizing them to use, propagate,
modify
or
convey a specific copy of the covered work, then the patent license you grant
is
automatically
extended
to
all
recipients
of
the
covered
work
and
works
based
on
it.
A patent license is "discriminatory" if
it
does
not
include
within
the
scope
of
its
coverage,
prohibits
the
exercise
of,
or
is
conditioned
on
the
non-exercise
of
one
or
more
of
the
rights
that are specifically granted under this License.
You
may
not
convey
covered
work
if
you
are
party
to
an
arrangement
with
third
party
that
is
in
the
business
of
distributing
software,
under
which
you
make
payment
to
the
third
party
based
on
the
extent
of
your
activity
of
conveying
the
work,
and
under
which
the
third
party
grants,
to
any
of
the
parties
who
would
receive
the
covered
work
from
you,
discriminatory
patent
license
(a) in connection with copies of the covered work conveyed by you
(or
copies
made
from
those
copies),
or
(b)
primarily
for
and
in
connection
with
specific
products
or
compilations
that
contain
the
covered
work,
unless
you
entered
into
that
arrangement,
or
that
patent
license
was
granted,
prior
to
28
March
2007.
Nothing in this License shall be construed as excluding or limiting
any implied license or other defenses to infringement that may
otherwise be available to you under applicable patent law.
12.[7]
No
Surrender
of
Others'
Freedom.
If conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License.
If you cannot convey the
Program, or other covered work, so as to satisfy simultaneously your
obligations under this License and any other pertinent obligations, then as
a consequence you may not convey it at all.
For example, if you agree to terms
that obligate you to collect a royalty for further conveying from those to whom
you convey the Program, the only way you could satisfy both those terms and
this License would be to refrain entirely from conveying the Program.
13.
Use
with
the
GNU
Affero
General
Public
License.
Notwithstanding any other provision of this License, you have permission to
link
any covered work with a work licensed
under
version
(or
any
later
version
published
by
the
Free
Software
Foundation)
of
the
GNU
Affero
General
Public
License,
and to convey the resulting combination.
The
of
this
License
will
continue
to
apply
to
your
covered
work
but
will
not
apply
to
the
work
with
which
it
is
linked,
which will remain governed by the GNU Affero General Public License.
14.[9]
Revised
Versions
of
this
License.
The Free Software Foundation may publish revised and/or new versions of
the GNU General Public License from time to time.
Such new versions will be
similar
in
spirit
to the present version, but may differ in detail to address new problems or concerns.
Each version is given a distinguishing version number.
If the
Program specifies that a certain numbered version of the GNU General
Public License "or any later version" applies to it, you have the
option of following the terms and conditions either of that numbered
version or of any later version published by the Free Software
Foundation.
If
the
Program
does
not
specify
version
number
of
the
GNU
General
Public
License,
you may choose any version ever published by the Free Software Foundation.
If
the
Program
specifies
that
proxy
can
decide
whether
future
versions
of
the
GNU
General
Public
License
shall
apply,
that
proxy's
public
statement
of
acceptance
of
any
version
is
permanent
authorization
for
you
to
choose
that
version
for
the
Program.
Later license versions may grant you additional or different
permissions.
However,
no
additional
obligations
are imposed on any author or copyright holder as a result of your choosing to follow a later version.
15.[11]
Disclaimer
of
Warranty.
THERE
IS
NO
WARRANTY
FOR
THE
PROGRAM,
TO
THE
EXTENT
PERMITTED
BY
APPLICABLE
LAW.
EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE.
THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
IS WITH YOU.
SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
16.[12]
Limitation
of
Liability.
IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
SUCH DAMAGES.
17.
Interpretation
of
Sections
15
and
16.
If the disclaimer of warranty and limitation of liability provided
above cannot be given local legal effect according to their terms,
reviewing courts shall apply local law that most closely approximates
an absolute waiver of all civil liability in connection with the
Program, unless a warranty or assumption of liability accompanies a
copy of the Program in return for a fee.
END OF TERMS AND CONDITIONS

HOW
TO
APPLY
THESE
TO
YOUR
NEW
PROGRAMS
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program.
It
is
safest
to
attach
them
to
the
start
of
each
source
file
to
most
effectively
state
the
exclusion
of
warranty;
and
each
file
should
have
at
least
the
"copyright"
line
and
pointer
to
where
the
full
notice
is
found.

not,

Also add information on how to contact you by electronic and paper mail.
If the program does terminal interaction, make it output a short notice like this when it starts in an
interactive
mode:
Gnomovision
version
69,
Copyright (C)
year

Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `Show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `Show c' for details.
The hypothetical commands `Show w' and `Show c' should show the appropriate
parts of the General Public License.
Of course, the commands you use may
be called something other than `Show w' and `Show c'; for a GUI interface,
you would use an "About box" instead.
You
should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the program,
if
necessary.
Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the program `Gnomovision'

makes
