GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS
FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains a no-
tice 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 modications 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 modication are not cov-
ered 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 de-

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 recipi-
ents 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 oer 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, pro-
vided that you also meet all of these conditions:
a) You must cause the modied 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.
c) If the modified program normally reads commands interactively
when run, you must cause it, when started running for such interac-
