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 convey 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 an idea of what it does.

appropriate parts of the General Public License. Of course, the commands
you use may be called something other than 'show w' and 'show c' ; they

Gnu GeneraL puBLic LicenSe
Version 3, 29 June 2007
Copyright © 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.
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
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
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
termS anD conDitionS
"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
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
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
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:
