you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source
code. And you must show them these terms so they know their rights. 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 patents. We wish to avoid the danger that redistributors of a free program
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 modification follow. 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 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 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. 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 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. 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 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 system on which the executable runs, unless that component itself
accompanies the executable. If distribution of executable or object code is made by offering access to copy from a
designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the
source code, even though third parties are not compelled to copy the source along with the object code. 4. You may not
