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.
