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 Program" means either the Program or any deriv-
ative 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.
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 copy-
right 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 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 them-
selves, then this License, and its terms, do not apply to those sections when you distribute them as sepa-
rate 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 execut-
able 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 machine-readable 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 modifications to it. For an executable work,
complete source code means all the source code for all modules it contains, plus any associated interface
definition files, plus the scripts used to control compilation and installation of the executable. However, as
a special exception, the source code distributed need not include anything that is normally distributed (in
either source or binary form) with the major components (compiler, kernel, and so on) of the operating
