Copyright (C)
2007 Free Software Foundation, Inc. <
http://fsf.org/>
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 a 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 a 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 copyright 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" a work means to copy
from or adapt all
or part
of the work
in a fashion requiring copyright permission, other than the making
of an
exact copy. The resulting work is called a
"modified version" of the
earlier work
or a work
"based on" the earlier work.
A
"covered work" means either the unmodified Program
or a work based
on the Program.
To
"propagate" a work means to do anything
with it that, without
permission, would make you directly
or secondarily liable for
infringement under applicable copyright
law, except executing it on a
computer
or modifying a private copy. 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. 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 a 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 a 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 a 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 a Standard Interface for which an
implementation is available to the public
in source code form. A
"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 copyright
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 control copyright. Those thus making
or running the covered works
for you must do so exclusively on your behalf, under your direction
and control, on terms 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 copyright 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 technological 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 a means
of enforcing, against the work
's
users, your
or third parties
' legal rights to forbid circumvention of
technological measures.
4. 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 a 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. Conveying Modified Source Versions.
You may convey a work based on the Program,
or the modifications to
produce it
from the Program,
in the form
of source code under the
terms
of section
4, provided that you also meet all
of these conditions:
a) The work must carry prominent notices stating that you modified
it,
and giving a 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 a 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,
and which are
not combined
with it such as to form a larger program,
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 a covered work
in an aggregate does
not cause this License to apply to the other
parts
of the aggregate.
6. 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, to give anyone who possesses the object code either (
1) 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) 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.
A separable portion
of the object code, whose source code is excluded
from the Corresponding Source as a System
Library, need
not be
included
in conveying the object code work.
A
"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 a
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 a User Product means any methods,
procedures, authorization keys,
or other information required to install
and execute modified versions
of a 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, a User Product,
and the conveying occurs as
part
of a 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 a
requirement to continue to provide support service, warranty,
or updates
for a work that
has been modified
or installed
by the recipient,
or for
the User Product
in which it
has been modified
or installed. Access to a
network 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 a covered work, you may (
if authorized
by the copyright holders
of
that material) supplement the terms
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, contains a notice stating that it is
governed
by this License along
with a term that is a 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. 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,
and will automatically terminate your rights under
this License (including any patent licenses granted under the third
paragraph
of section
11).
However,
if you cease all violation
of this License,
then your
license
from a particular copyright holder is reinstated (a)
provisionally, unless
and until the copyright holder explicitly
and
finally terminates your license,
and (b) permanently,
if the copyright
holder fails to notify you
of the violation
by some reasonable means
prior to
60 days after the cessation.
Moreover, your license
from a particular copyright holder is
reinstated permanently
if the copyright holder notifies you
of the
violation
by some reasonable means, this is the first time you have
received notice
of violation
of this License (for any work)
from that
copyright holder,
and you cure the violation prior to
30 days after
your receipt
of the notice.
Termination
of your rights under this section does
not terminate the
licenses
of parties who have received copies
or rights
from you under
this License.
If your rights have been terminated
and not permanently
reinstated, you do
not qualify to receive new licenses for the same
material under section
10.
9. 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. 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 a 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.
A
"contributor" is a copyright 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".
A 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 a 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.
In the following three paragraphs, a
"patent license" is any express
agreement
or commitment, however denominated,
not to enforce a patent
(such as an express permission to practice a patent
or covenant
not to
sue for patent infringement). To
"grant" such 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) arrange to deprive yourself
of the benefit
of 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 a covered
work
if you are a party to an arrangement
with a 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, a 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. 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 a
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
or combine any covered work
with a work licensed
under version
3 of the GNU Affero General Public License into a single
combined work,
and to convey the resulting work. The terms
of this
License will continue to apply to the part which is the covered work,
but the special requirements
of the GNU Affero General Public License,
section
13, concerning interaction through a network will apply to the
combination as such.
14. 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 a 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 a proxy can decide which future
versions
of the GNU General Public License can be used, that proxy
's
public statement
of acceptance
of a version permanently authorizes you
to choose that version for the Program.
Later license versions may give 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

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

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.

How to Apply These Terms 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 a pointer to
where the full notice is found.
<one line to give the program
's name and a brief idea of what it does.>
Copyright (C) <year> <name
of author>
This program is free software: you can redistribute it
and/
or modify
it under the terms
of the GNU General Public License as published
by
the Free Software Foundation, either version
3 of the License,
or
(at your option) any later version.
This program is distributed
in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty
of
MERCHANTABILITY
or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
You should have received a copy
of the GNU General Public License
along
with this program.
If not, see <
http://www.gnu.org/licenses/>.
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:
<program> Copyright (C) <year> <name
of author>
This program 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, your program
's commands
might be different; for a GUI interface, you would use an
"about box".
You should also get your employer (
if you work as a programmer)
or school,
if any, to sign a
"copyright disclaimer" for the program,
if necessary.
For more information on this,
and how to apply
and follow the GNU GPL, see
<
http://www.gnu.org/licenses/>.
The GNU General Public License does
not permit incorporating your program
into proprietary programs.
If your program is a subroutine
library, you
may consider it more useful to permit linking proprietary applications
with
the
library.
If this is what you want to do, use the GNU Lesser General
Public License instead
of this License.
