"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
So
urce 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.
