a) The work must carry prominent notices stating that you modified it, and giving a relevant date.
b) The work must carry prominent notices stating that it is released under this License
and any conditions added under section 7. This requirement modifies the requirement in section 4 to
“keep intact all notices”.
c) You must license the entire work, as a whole, under this License to anyone who comes into possession
of a copy. This License will therefore apply, along with any applicable section 7 additional terms, to the
whole of the work, and all its parts, regardless of how they are packaged. This License gives no
permission to license the work in any other way, but it does not invalidate such permission if you have
separately received it.
d) If the work has interactive user interfaces, each must display Appropriate Legal Notices; however, if
the Program has interactive interfaces that do not display Appropriate Legal Notices, your work
need not make them do so.
A compilation of a covered work with other separate and independent works, which are not by their
nature extensions of the covered work, and which are not combined with it such as to form a larger
program, in or on a volume of a storage or distribution medium, is called an “aggregate” if
the compilation and its resulting copyright are not used to limit the access or legal rights of
the compilation's users beyond what the individual works permit. Inclusion of a covered work in an
aggregate does not cause this License to apply to the other parts of the aggregate.
6. Conveying Non-Source Forms.
You may convey a covered work in object code form under the terms of sections 4 and 5, provided that
you also convey the machine-readable Corresponding Source under the terms of this License, in one of
these ways:
a) Convey the object code in, or embodied in, a physical product (including a physical distribution
medium), accompanied by the Corresponding Source fixed on a durable physical medium customarily
used for software interchange.
b) Convey the object code in, or embodied in, a physical product (including a physical distribution
medium), accompanied by a written offer, valid for at least three years and valid for as long as you offer
spare parts or customer support for that product model, to give anyone who possesses the object code
either (1) a copy of the Corresponding Source for all the software in the product that is covered by this
License, on a durable physical medium customarily used for software interchange, for a price no more
