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
