The “Program”, below, refers to any such program or work, and
a “work based on the Program” means either the Program or
any derivative work under copyright law: that is to say, a work
containing the Program or a portion of it, either verbatim or
with modifications and/or translated into another language.
(Hereinafter, translation is included without limitation in the
term “modification”.) Each licensee is addressed as “you”.
Activities other than copying, distribution and modification are
not covered by this License; they are outside its scope. The act
of running the Program is not restricted, and the output 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). Whether that is true depends on what the
Program does.
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
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
