modifies the requirement in section 4 to "keep intact all notices".

<br/>

<br/>

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.

These requirements apply to the modified work as a whole.  If

identifiable sections of that work are not derived from the Program,

and can be reasonably considered independent and separate works in

themselves, then this License, and its terms, do not apply to those

sections when you distribute them as separate works.  But when you

distribute the same sections as part of a whole which is a work based

on the Program, the distribution of the whole must be on the terms of

this License, whose permissions for other licensees extend to the

entire whole, and thus to each and every part regardless of who wrote it.
