from the Program is covered only if its contents
constitute a work based on the Program (independent
of having been made by running the Program).

does.
1. You may copy and distribute verbatim copies
of the Programʼs source code as you receive it, in
any medium, provided that you conspicuously and
appropriately publish on each copy an appropriate
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 fee.
2. You may modify your copy or copies of the Program
or any portion of it, thus forming a work based on the
Program, and copy and distribute such modifications
or work under the terms of Section 1 above, provided
that you also meet all of these conditions:
a) You must cause the modified files to carry
prominent notices stating that you changed the files
and the date of any change.
b) You must cause any work that you distribute or
publish, that in whole or in part contains or is derived
from the Program or any part thereof, to be licensed
as a whole at no charge to all third parties under the
terms of this License.
c) If the modified program normally reads commands
interactively when run, you must cause it, when
started running for such interactive use in the most
ordinary way, to print or display an announcement
including an appropriate copyright notice and a notice
that there is no warranty (or else, saying that you
provide a warranty) and that users may redistribute
