1. You may copy and distribute verbatim copies of the Program‘s
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an approp-
riate copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any warranty;
and give any other recipients of the Program a copy of this License
along with the Program.
You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a

2. You may modify your copy or copies of the Program or any porti-

such an announcement, your work based on the Program is not re-

These requirements apply to the modified work as a whole. If iden-
tifiable 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 tho-
se sections when you distribute them as separate works. But when
you distribute the same sections as part of a whole which is a work
