be distributed under the terms of this General Public License.
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 modications and/or translated into another language.
(Hereinafter, translation is included without limitation in the
term “modication”.) Each licensee is addressed as “you”.
Activities other than copying, distribution and modication
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 oer 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 modications or work under the
terms of Section 1 above, provided that you also meet all of
these conditions:
a) You must cause the modied les to carry prominent
notices stating that you changed the les 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.
