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 Gen-
eral 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 deriva-
tive 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 re-
stricted, 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 war-
ranty; 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 modifica-
tions 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 the program under
