A “covered work” means either the unmodifi ed
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
modifi cation), 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 modifi cations
to it. “Object code” means any non-source form of
a work.
A “Standard Interface” means an interface that
either is an offi cial standard defi ned by a recognized
standards body, or, in the case of interfaces
specifi ed 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 specifi c
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 unmodifi ed in performing those
activities but which are not part of the work. For
example, Corresponding Source includes interface
defi nition fi les associated with source fi les for the
work, and the source code for shared libraries and
specifi
dynamically linked subprograms that the work is
cally designed to require, such as by intimate
data communication or control fl ow 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 affi rms your unlimited
permission to run the unmodifi ed Program. The
output from running a covered work is covered
by this License only if the output, given its
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 “modifi ed
version” of the earlier work or a work “based on”
the earlier work.
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 modifi cations
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.
content, constitutes a covered work. This License
acknowledges your rights of fair use or other
equivalent, as provided by copyright law.
Conveying under any other circumstances is
permitted solely under the conditions stated below.
Sublicensing is not allowed; section 10 makes it
unnecessary.
