We protect your rights with two steps: (1) copyright the software,
and (2) offer you this license which gives you legal permission to
copy, distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software. If the software is modified by someone else and passed
on, we want its recipients to know that what they have is not the
original, so that any problems introduced by others will not reflect
on the original authors' reputations.
Finally, any free program is threatened constantly by software pa-
tents. We wish to avoid the danger that redistributors of a free pro-
gram will individually obtain patent licenses, in effect making the
program proprietary. To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at all.
The precise terms and conditions for copying, distribution and mo-
dification follow.

TERMS AND CONDITIONS FOR COPYING,
DISTRIBUTION AND MODIFICATION
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 Pro-
gram" means either the Program or any derivative work under co-
pyright law: that is to say, a work containing the Program or a porti-
on of it, either verbatim or with modifications and/or translated into
another language. (Hereinafter, translation is included without limi-
tation in the term "modification".) Each licensee is addressed as "you".
Activities other than copying, distribution and modification are not co-
vered 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 (indepen-
dent 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 approp-
