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.
