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 modifi cations and/or
translated into another language. (Hereinafter,
translation is included without limitation in the term
"modifi cation".) Each licensee is addressed as
"you".
Activities other than copying, distribution and
modifi 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 modifi cations or work under the terms of
Section 1 above, provided that you also meet all of
these conditions :
a) You must cause the modifi ed fi les to carry
prominent notices stating that you changed the
fi 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 modifi ed 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 these
conditions, and telling the user how to view a
copy of this License. (Exception:if the Program
itself is interactive but does not normally print
such an announcement, your work based
on the Program is not required to print an
announcement.)
These requirements apply to the modifi ed work as
a whole. If identifi able sections of that work are not
derived from the Program, and can be reasonably
considered independent and separate works in
themselves, then this License, and its terms, do not
apply to those sections when you distribute them as
separate works. But when you distribute the same
sections as part of a whole which is a work based on
the Program, the distribution of the whole must be
on the terms of this License, whose permissions for
other licensees extend to the entire whole, and thus
to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights
or contest your rights to work written entirely by you ;
rather, the intent is to exercise the right to control the
distribution of derivative or collective works based on
the Program. In addition, mere aggregation of another
work not based on the Program with the Program (or
with a work based on the Program)on a volume of
a storage or distribution medium does not bring the
other work under the scope of this License.
3. You may copy and distribute the Program (or a
work based on it, under Section 2)in object code
or executable form under the terms of Sections 1
and 2 above provided that you also do one of the
following :
a) Accompany it with the complete corresponding
machine-readable source code, which must
be distributed under the terms of Sections 1
and 2 above on a medium customarily used for
software interchange ; or,
b) Accompany it with a written offer, valid for at
least three years, to give any third party, for a
charge no more than your cost of physically
performing source distribution, a complete
machinereadable copy of the corresponding
source code, to be distributed under the
terms of Sections 1 and 2 above on a medium
customarily used for software interchange ; or,
c) Accompany it with the information you received
as to the offer to distribute corresponding
source code. (This alternative is allowed only
for noncommercial distribution and only if
you received the program in object code or
executable form with such an offer, in accord
with Subsection b above.)
The source code for a work means the preferred
form of the work for making modifi cations to it. For
an executable work, complete source code means all
the source code for all modules it contains, plus any
