Terms & conditions for copying, distribution, & modication
0. This License applies to any program or other work which
contains a notice placed by the copyright holder saying it may
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 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 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.
