GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION
AND MODIFICATION
1. This Licens e applies to an y prog ram or ot her wor k which contains a not ice pla ced b y
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 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 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.
2. 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.
3. 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, 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 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 modified work as a whole. If identifiable 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.
4. 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,
