\section{Preamble}

  The licenses for most software are designed to take away your freedom
to share and change it.  By contrast, the GNU General Public License is
intended to guarantee your freedom to share and change free
software---to make sure the software is free for all its users.  We, the
Free Software Foundation, use the GNU General Public License for most of
our software; it applies also to any other program whose authors commit
to using it.  \sout{(Some Free Software Foundation software is covered
by the GNU Lesser General Public License instead.)} You can apply it to
your programs, too.

  When we speak of free software, we are referring to freedom, not
price.  Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it if
you want it, that you can change the software or use pieces of it in new
free programs\sout{;}\textbf{,} and that you know you can do these
things.

  To protect your rights, we need to make requirements that forbid
anyone to deny you these rights or to ask you to surrender the rights.
\sout{These restrictions translate to} \textbf{Therefore, you have}
certain responsibilities \sout{for you} if you distribute copies of the
software, or if you modify it.

  For example, if you distribute copies of such a program, whether
gratis or for a fee, 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.

  Developers that use the GNU GPL protect your rights with two steps:
(1) assert copyright on the software, and (2) offer you this License
which gives you legal permission to copy, distribute and/or modify the
software.

  For the developers' and \sout{author's} \textbf{authors'} protection,
the GPL clearly explains that there is no warranty for this free
software.  \sout{If the software is modified by someone else and passed
on, the GPL ensures that recipients are told that what they have is not
the original, so that any problems introduced by others will not reflect
on the original authors' reputations.} \textbf{For both users' and
authors' sake, the GPL requires that modified versions be marked as
changed, so that their problems will not be associated erroneously with
the original version.}

  \sout{Some countries have adopted laws prohibiting software that
enables users to escape from Digital Restrictions Management.}
\textbf{Some computers are designed to deny users access to install or
run modified versions of the software inside them.}  \sout{DRM}
\textbf{This} is fundamentally incompatible with the purpose of the GPL,
which is to protect users' freedom\sout{;} \textbf{to change the
software.}  \sout{therefore} \textbf{Therefore}, the GPL ensures that
the software it covers will \sout{neither be subject to, nor subject
other works to, digital restrictions from which escape is forbidden}
\textbf{not be restricted in this way}.

  Finally, every program is threatened constantly by software patents.
\textbf{States should not allow patents to restrict development and use
of software on general-purpose computers, but in places where they do,
we} \sout{We} wish to avoid the special danger that redistributors of a
free program will individually obtain patent licenses, in effect making
the program proprietary.  To prevent this, the GPL \sout{makes it clear}
\textbf{assures} that \sout{any patent must be licensed for everyone's
free use or not licensed at all} \textbf{patents cannot be used to
render the program non-free}.

  \sout{The precise terms and conditions for copying, distribution and
modification follow.}

\renewcommand{\thesection}{\arabic{section}.}
\section{Definitions.}

\sout{A ``licensed program'' means any program or other work distributed
under this License.} \sout{``The Program'' 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 modified or
unmodified.} \textbf{In this License, each licensee is addressed as
``you,'' while ``the Program'' refers to any work of authorship licensed
under this License.}  \sout{Throughout this License, the term
``modification'' includes, without limitation, translation and
extension.}  \textbf{A ``modified'' work includes, without limitation,
versions in which material has been translated or added. A work ``based
on'' another work means any modified version, formation of which
requires permission under applicable copyright law.}  A ``covered work''
means either the \textbf{unmodified} Program or \sout{any} \textbf{a}
work based on the Program.  \sout{Each licensee is addressed as
``you''.}

  To ``propagate'' a work means doing anything with it that requires
permission under applicable copyright law, \sout{other than}
\textbf{except} executing it on a computer\textbf{,} or making
\sout{private} modifications \textbf{that you do not share}. \sout{This}
\textbf{Propagation} includes copying, distribution (with or without
modification), \textbf{making available to the public,}
\sout{sublicensing,} and in some countries other activities as well.
\textbf{To ``convey'' a work means any kind of propagation that enables
other parties to make or receive copies, excluding
sublicensing.}

  \textbf{A party's ``essential patent claims'' in a work are all patent
claims that the party can give permission to practice, whether already
acquired or to be acquired, that would be infringed by making, using, or
selling the work.}

\section{Source Code.}

  The ``source code'' for a work means the preferred form of the work
for making modifications to it.  ``Object code'' means any non-source
version of a work.

\textbf{The ``System Libraries'' of an executable work include every
subunit such that (a) the identical subunit is normally included as an
adjunct in the distribution of either a major essential component
(kernel, window system, and so on) of the specific operating system (if
any) on which the object code runs, or a compiler used to produce the
object code, or an object code interpreter used to run it, and (b) the
subunit (aside from possible incidental extensions) serves only to
enable use of the work with that system component or compiler or
interpreter, or to implement a widely used or standard interface for
which an implementation is available to the public in source code
form.}

The ``\sout{Complete} Corresponding Source \sout{Code}'' for a work in
object code form means all the source code needed to \sout{understand,
adapt, modify, compile, link} \textbf{generate}, install, and
\textbf{(for an executable work)} run the \textbf{object code and to
modify the} work, \sout{excluding} \textbf{except its System Libraries,
and except} general-purpose tools \textbf{or generally available free
programs which are} used \textbf{unmodified} in performing those
activities but which are not part of the work.  For example, \sout{this}
\textbf{Corresponding Source} includes \sout{any} scripts used to
control those activities, \textbf{interface definition files associated
with the program source files,} and \sout{any} \textbf{the source code
for} shared libraries and dynamically linked subprograms that the work
is \textbf{specifically} designed to require, such as by \sout{intimate}
\textbf{complex} data communication or control flow between those
subprograms and other parts of the work\sout{, and interface definition
files associated with the program source files}.

  \textbf{The} \sout{Complete} Corresponding Source \sout{Code} also
includes any encryption or authorization \sout{codes} \textbf{keys}
necessary to install and/or execute \sout{the} \textbf{modified versions
from} source code \sout{of the work, perhaps modified by you,} in the
recommended or principal context of use, such that \sout{its functioning
in all circumstances is identical to that of the work, except as altered
by your modifications} \textbf{they can implement all the same
functionality in the same range of circumstances.}  \textbf{(For
instance, if the work is a DVD player and can play certain DVDs, it must
be possible for modified versions to play those DVDs.  If the work
communicates with an online service, it must be possible for modified
versions to communicate with the same online service in the same way
such that the service cannot distinguish.)}  \sout{It also includes any
decryption codes necessary to access or unseal the work's output.}
\sout{Notwithstanding this, a code} \textbf{A key} need not be included
in cases where use of the work normally implies the user already has
\sout{it} \textbf{the key and can read and copy it, as in privacy
applications where users generate their own keys.  However, the fact
that a key is generated based on the object code of the work or is
present in hardware that limits its use does not alter the requirement
to include it in the Corresponding Source.}  

\textbf{The Corresponding Source may include portions which do not
formally state this License as their license, but qualify under section
7 for inclusion in a work under this License.}

  \textbf{The} \sout{Complete} Corresponding Source \sout{Code} need not
include anything that users can regenerate automatically from other
parts of the \sout{Complete} Corresponding Source \sout{Code}.

\sout{As a special exception, the Complete Corresponding Source Code
need not include a particular subunit if (a) the identical subunit is
normally included as an adjunct in the distribution of either a major
essential component (kernel, window system, and so on) of the operating
system on which the executable runs or a compiler used to produce the
executable or an object code interpreter used to run it, and (b) the
subunit (aside from possible incidental extensions) serves only to
enable use of the work with that system component or compiler or
interpreter, or to implement a widely used or standard interface, the
implementation of which requires no patent license not already generally
available for software under this License.}

\section{Basic Permissions.}

  All rights granted under this License are granted for the term of
copyright on the Program, and are irrevocable provided the stated
conditions are met.  This License explicitly affirms your unlimited
permission to run the \textbf{unmodified} Program.  The output from
running it is covered by this License only if the output, given its
content, constitutes a \sout{work based on the Program} \textbf{covered
work}.  This License acknowledges your rights of ``fair use'' or other
equivalent, as provided by copyright law.

This License \sout{gives unlimited} \sout{permission} \textbf{permits
you} to \sout{privately modify} \textbf{make} and run \textbf{privately
modified versions of} the Program, \textbf{or have others make and run
them on your behalf.} \sout{provided you do not} \textbf{However, this
permission terminates, as to all such versions, if you} bring suit
\textbf{against anyone} for patent infringement \sout{against anyone}
\textbf{of any of your essential patent claims in any such version,} for
making, using\textbf{, selling} or \sout{distributing} \textbf{otherwise
conveying} \sout{their own works} \textbf{a work} based on the Program
\textbf{in compliance with this License}.

  Propagation of covered works \textbf{other than conveying} is
permitted without limitation \sout{provided it does not enable parties
other than you to make or receive copies}.  \textbf{Sublicensing is not
allowed; section 10 makes it unnecessary.}  \sout{Propagation which does
enable them to do so} \textbf{Conveying} is permitted \sout{, as
``distribution'',} under the conditions \sout{of sections 4-6}
\textbf{stated} below.

\section{\sout{Digital Restrictions Management} \textbf{No Denying
 Users' Rights Through Technical Measures}.}

\sout{As a free software license, this License intrinsically disfavors
technical attempts to restrict users' freedom to copy, modify, and share
copyrighted works.  Each of its provisions shall be interpreted in light
of this specific declaration of the licensor's intent.}  Regardless of
any other provision of this License, no permission is given \sout{to
distribute covered works that illegally invade users' privacy, nor} for
modes of \sout{distribution} \textbf{conveying} that deny users that run
covered works the full exercise of the legal rights granted by this
License.

  No covered work constitutes part of an effective technological
\textbf{``}protection\textbf{''} measure \textbf{under section 1201 of
Title 17 of the United States Code.}\sout{: that is to say, distribution
of a covered work as part of a system to generate or access certain data
constitutes general permission at least for development, distribution
and use, under this License, of other software capable of accessing the
same data.}  \textbf{When you convey a covered work, you waive any legal
power to forbid circumvention of technical measures that include use of
the covered work, and you disclaim any intention to limit operation or
modification of the work as a means of enforcing the legal rights of
third parties against the work's users.}  

\setcounter{v2section}{1}
\renewcommand{\thesection}{\arabic{section}.[\arabic{v2section}]}
\section{Verbatim Copying.}

 You may copy and \sout{distribute} \textbf{convey} 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; keep intact all license notices and
notices of the absence of any warranty; \textbf{and} give all
recipients\textbf{,} \sout{of} \textbf{along with} the Program\textbf{,}
a copy of this License \sout{along with the Program;} and \sout{obey any
additional terms present on parts of the Program in accord with}
\textbf{the central list (if any) required by} section 7.  \textbf{The
recipients of these copies will possess all the rights granted by this
License (with any added terms under section 7).}

  You may charge \sout{a fee} \textbf{any price or no price} for
\sout{the physical act of transferring a copy} \textbf{each copy that
you convey}, and you may \sout{at your option} offer \textbf{support or}
warranty protection for a fee.

\stepcounter{v2section}
\section{\sout{Distributing} \textbf{Conveying} Modified Source Versions.}

  \sout{Having modified a copy of the Program under the conditions of
section 2, thus forming a work based on the Program, you} \textbf{You}
may copy and \sout{distribute} \textbf{convey} \sout{such modifications
or} \textbf{a} work \textbf{based on the Program, or the modifications
to produce it from the Program,} in the form of source code under the
terms of section 4 above, provided that you also meet all of these
conditions:

\renewcommand{\theenumi}{\alph{enumi}}
\begin{enumerate}
\item The modified work must carry prominent notices stating that you
      changed the work and the date of any change.

\item You must license the entire \sout{modified} work, as a whole,
    under this License to anyone who comes into possession of a copy.
    This License must apply, unmodified except as permitted by section 7
    below, to the whole of the work\textbf{, and all its parts,
    regardless of how they are packaged}.  This License gives no
    permission to license the work in any other way, but it does not
    invalidate such permission if you have separately received it.

\item If the modified work has interactive user interfaces, each must
      include a convenient feature that displays an appropriate
      copyright notice, and tells the user that there is no warranty for
      the program (or that you provide a warranty), that users may
      \sout{redistribute} \textbf{convey} the modified work under
      \sout{these conditions} \textbf{this License}, and how to view a
      copy of this License together with the central list (if any) of
      other terms in accord with section 7.  \textbf{Specifically,}
      \sout{If} \textbf{if} the interface presents a list of user
      commands or options, such as a menu, a command to display this
      information must be prominent in the list\sout{.}\textbf{;}
      \sout{Otherwise} \textbf{otherwise}, the modified work must
      display this information at startup\sout{---except in the case
      that the Program has such interactive modes and does not display
      this information at startup}.  \textbf{However, if the Program has
      interactive interfaces that do not comply with this subsection,
      your modified work need not make them comply.}

\end{enumerate}

\noindent \sout{These requirements apply to the modified work as a
whole.} \sout{If} \textbf{To the extent that} identifiable sections of
\sout{that} \textbf{the modified} work, added by you, 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 \sout{distribute} \textbf{convey} them
as separate works\textbf{, not specifically} for use \sout{not} in
combination with the Program.  \sout{But when you distribute the same
sections for use in combination with covered works, no matter in what
form such combination occurs, the whole of the combination must be
licensed under this License, whose permissions for other licensees
extend to the entire whole, and thus to every part of the whole. Your
sections may carry other terms as part of this combination in limited
ways, described in section 7.}

\sout{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.}

A compilation of a covered work with other separate and independent
works, which are not by their nature extensions of the covered work, in
or on a volume of a storage or distribution medium, is called an
``aggregate'' if the \textbf{compilation and its resulting} copyright
\sout{resulting from the compilation is} \textbf{are} not used to limit
the \textbf{access or} legal rights of the compilation's users beyond
what the individual works permit. \sout{Mere inclusion}
\textbf{Inclusion} of a covered work in an aggregate does not cause this
License to apply to the other parts of the aggregate.

\stepcounter{v2section}
\section{\textbf{Conveying} Non-Source \sout{Distribution} \textbf{Forms.}}
  
You may copy and \sout{distribute} \textbf{convey} a covered work in
\sout{Object Code} \textbf{object code} form under the terms of sections
4 and 5, provided that you also \sout{distribute} \textbf{convey} the
machine-readable \sout{Complete} Corresponding Source \sout{Code (herein
the ``Corresponding Source'')} under the terms of this License, in one
of these ways:

\begin{enumerate}
\item \sout{Distribute} \textbf{Convey} the \sout{Object Code}
    \textbf{object code} in a physical product (including a physical
    distribution medium), accompanied by the Corresponding Source
    \sout{distributed} \textbf{fixed} on a durable physical medium
    customarily used for software interchange\textbf{.}\sout{; or,}
  
\item \sout{Distribute} \textbf{Convey} the \sout{Object Code}
    \textbf{object code} in a physical product (including a physical
    distribution medium), accompanied by a written offer, valid for at
    least three years and valid for as long as you offer spare parts or
      customer support for that product model, to give any third
    party\sout{, for a price no more than ten times your cost of
    physically performing source distribution,} a copy of
    the Corresponding Source for all the software in the product that is
    covered by this License, on a durable physical medium customarily
    used for software interchange\textbf{, for a
    price no more than your reasonable cost of physically
    performing this conveying of source.}\sout{; or,}
    
\renewcommand{\labelenumi}{[\alph{enumi}1.}
\setcounter{enumi}{1}
\item \textbf{Convey the object code in a physical product
    (including a physical distribution medium), accompanied by a written
    offer, valid for at least three years and valid for as long as you
      offer spare parts or customer support for that product model, to
      provide
    access to copy the Corresponding Source from a network server at no
     charge.}]

\renewcommand{\labelenumi}{\alph{enumi}.}
\item \sout{Privately distribute} \textbf{Convey individual copies of}
    the \sout{Object Code} \textbf{object code} with a copy of the
    written offer to provide the Corresponding Source.  This alternative
    is allowed only \sout{for occasional noncommercial distribution}
    \textbf{occasionally and noncommercially}, and only if you received
    the \sout{Object Code} \textbf{object code} with such an offer, in
    accord with \sout{Subsection b above} \textbf{subsection 6b or
      6b1}.\sout{Or,}

\item \sout{Distribute} \textbf{Convey} the \sout{Object Code}
    \textbf{object code} by offering access \sout{to copy it} from a
    designated place, and offer equivalent access to \sout{copy} the
    Corresponding Source in the same way through the same place
    \textbf{at no extra charge}. You need not require recipients to copy
    the Corresponding Source along with the \sout{Object Code}
    \textbf{object code}.

    [If the place to copy the \sout{Object Code} \textbf{object code} is
    a network server, the Corresponding Source may be on a different
    server that supports equivalent copying facilities, provided you
    have explicitly arranged with the operator of that server to keep
    the Corresponding Source available for as long as needed to satisfy
    these requirements, and provided you maintain clear directions next
    to the \sout{Object Code} \textbf{object code} saying where to find
    the Corresponding Source.]

\item \textbf{Convey the object code using peer-to-peer transmission
    provided you know that, and inform other peers where, the object
      code and Corresponding Source of
    the work are being offered to the general public at no
    charge under subsection 6d.}
\end{enumerate}

\sout{Distribution of the} \textbf{The} Corresponding Source
\textbf{conveyed} in accord with this section must be in a format that
is publicly documented, \sout{unencumbered by patents,} \textbf{with an
implementation available to the public in source code form,} and must
require no special password or key for unpacking, reading or copying.

\sout{The Corresponding Source may include portions which do not
formally state this License as their license, but qualify under section
7 for inclusion in a work under this License.}

\textbf{A separable portion of the object code, whose source code is
excluded from the Corresponding Source as a System Library, need not be
included in conveying the object code work.}

\renewcommand{\thesection}{\arabic{section}.}
\section{\sout{License Compatibility} \textbf{Additional
 Terms}.}

\sout{When you release a work based on the Program, you may include your
 own terms covering added parts for which you have, or can give,
 appropriate copyright permission, as long as those terms clearly permit
 all the activities that this License permits, or permit usage or
 relicensing under this License. Your terms may be written separately or
 may be this License plus additional written permission. If you so
 license your own added parts, those parts may be used separately under
 your terms, but the entire work remains under this License. Those who
 copy the work, or works based on it, must preserve your terms just as
 they must preserve this License, as long as any substantial portion of
 the parts they apply to are present.}

\textbf{You may have received the Program, or parts of it, under terms
that supplement the terms of this License.  These additional terms may
include additional permissions, as provided in subsection 7a, and
additional requirements, as provided in subsection 7b.  When you convey
copies of a covered work, unless the work also permits use under a
previous version of this License, it must list, in one central place in
the source code, the complete set of additional terms governing all or
part of the work.}

\renewcommand{\thesubsection}{\hspace{17pt}\alph{subsection}.\hspace{-5pt}}
\subsection{\textbf{Additional Permissions.}}

  \textbf{Additional permissions make exceptions from one or more of the
requirements of this License.  A license document containing a clause
that permits relicensing or conveying under this License shall be
treated as a list of additional permissions, provided that the license
document makes clear that no requirement in it survives such relicensing
or conveying.}

  \textbf{Any additional permissions that are applicable to the entire
Program are treated as though they were included in this License, as
exceptions to its conditions, to the extent that they are valid under
applicable law.  If additional permissions apply only to part of the
Program, that part may be used separately under those permissions, but
the entire Program remains governed by this License without regard to
the additional terms.}

 \sout{Aside from additional permissions, your terms may add limited
kinds of additional requirements on your added parts, as follows:}

\subsection{\textbf{Additional Requirements.}}

 \textbf{Additional requirements are terms that further constrain use,
modification or propagation of covered works.  This License affects only
the procedure for enforcing additional requirements, and does not assert
that they can be successfully enforced by the copyright holder.  Only
these kinds of additional requirements are allowed by this License:}

\renewcommand{\labelenumi}{\arabic{enumi})}
\begin{enumerate}
\setcounter{enumi}{-1}
\item \sout{a) They may} \textbf{terms that} require \sout{the}
       preservation of \sout{certain copyright notices, other}
       \textbf{specified reasonable} legal notices\sout{, and/or}
       \textbf{or} author attributions\sout{,}\textbf{; or}

\item \sout{and may} \textbf{terms that} require that the origin of the
\sout{parts} \textbf{material} they cover not be misrepresented,
\sout{and/or} \textbf{or} that \sout{altered} \textbf{modified} versions
of \sout{them} \textbf{that material} be marked \sout{in the source
code, or marked there} in specific reasonable ways\sout{,} as different
from the original version\sout{.}\textbf{; or}

\item \sout{b) They may state a disclaimer of} warranty \sout{and}
      \textbf{or} liability \textbf{disclaimers} \sout{in terms
      different} \textbf{that differ} from \sout{those used} \textbf{the
      disclaimers} in this License\sout{.}\textbf{; or}

\item \sout{c) They may} \textbf{terms that} prohibit or limit the use
      for publicity purposes of
specified names of \sout{contributors} \textbf{licensors or authors},
      \sout{and they may} \textbf{or that} require that certain
specified \textbf{trade names,} trademarks\textbf{, or service marks
      not} be used for publicity purposes \textbf{without express
      permission, other than} \sout{only} in \sout{the} ways
that are fair use under \textbf{applicable} trademark law\textbf{;}
      \sout{except with express permission.} \textbf{or}

\item \sout{d) They may} \textbf{terms that} require\textbf{,}
      \sout{that the work contain functioning facilities that
allow} \textbf{if a modified version of the material they cover is a
      work intended to interact with users through a computer network,
      that those} users \textbf{be able} to \sout{immediately} obtain
      copies of \sout{its} \textbf{the} \sout{Complete} Corresponding
      Source \sout{Code.} \textbf{of the work through the same network
      session; or}

\item \sout{e) They may impose software patent retaliation, which means}
\textbf{terms that wholly or partially terminate, or allow termination of,}
permission
for use of \sout{your added parts terminates or may be terminated, wholly or
partially, under stated conditions,} \textbf{the material they cover,}
for \sout{users closely related to any party that has filed}
\textbf{a user who files} a software patent lawsuit 
(\sout{i.e.}\textbf{that is}, a lawsuit alleging
that some software infringes a patent)\sout{.} 
\textbf{not filed in retaliation or defense against the earlier filing
      of another software patent lawsuit, or in which the allegedly
      infringing software includes some of the covered material,
      possibly in combination with other software; or}
\sout{The conditions must limit
retaliation to a subset of these two cases: 1. Lawsuits that lack the
justification of retaliating against other software patent lawsuits that
lack such justification. 2. Lawsuits that target part of this work, or
other code that was elsewhere released together with the parts you
added, the whole being under the terms used here for those
      parts.}
    
\item \textbf{terms that are precisely equivalent in type and extent to
      a requirement expressly stated in this License, or that deny
      permission for activities that are clearly not permitted,
      expressly or otherwise, by this License.}
\end{enumerate}

\sout{No other additional conditions are permitted in your terms;
therefore, no other conditions can be present on any work that uses this
License. This License does not attempt to enforce your terms, or assert
that they are valid or enforceable by you; it simply does not prohibit
you from employing them.}

\textbf{All other additional requirements, including attorney's fees
provisions, choice of law, forum, and venue clauses, arbitration
clauses, mandatory contractual acceptance clauses, requirements
regarding changes to the name of the work, and terms that require that
conveyed copies be governed by a license other than this License, are
prohibited.}

\subsection{\textbf{Terms Added or Removed By You.}}

\sout{When others modify the work, if they modify your parts of it, they
may release such parts of their versions under this License without
additional permissions, by including notice to that effect, or by
deleting the notice that gives specific permissions in addition to this
License. Then any broader permissions granted by your terms which are
not granted by this License will not apply to their modifications, or to
the modified versions of your parts resulting from their
modifications. However, the specific requirements of your terms will
still apply to whatever was derived from your added parts.}

\textbf{When you convey a copy of a covered work, you may at your option
remove any additional permissions from that copy, or from any part of
it.  Some additional permissions require their own removal in certain
cases when you modify the work.}

\textbf{Additional requirements are allowed only as stated in subsection
7b.  If the Program as you received it purports to impose any other
additional requirement, you may remove that requirement.}

\textbf{You may place additional permissions, or additional requirements
as allowed by subsection 7b, on material, added by you to a covered
work, for which you have or can give appropriate copyright permission.
Adding requirements not allowed by subsection 7b is a violation of this
License that may lead to termination of your rights under section 8.}

\textbf{If you add terms to a covered work in accordance with this
section, you must place, in the relevant source files, a statement of
the additional terms that apply to those files, or a notice indicating
where to find the applicable terms.}

\sout{Unless the work also permits distribution under a previous version
of this License, all the other terms included in the work under this
section must be listed, together, in a central list in the work.}

\section{Termination.}

  You may not propagate\sout{,} \textbf{or} modify \sout{or sublicense}
the Program except as expressly provided under this License.  Any
attempt otherwise to propagate\sout{,} \textbf{or} modify \sout{or
sublicense} the Program is void\sout{, and any copyright holder may
terminate your rights under this License at any time after having
notified you of the violation by any reasonable means within 60 days of
any occurrence}.  \textbf{If you violate this License, any copyright
holder may put you on notice by notifying you of the violation, by any
reasonable means, provided 60 days have not elapsed since the last
violation.  Having put you on notice, the copyright holder may then
terminate your license at any time.}  However, parties who have received
copies, or rights, from you under this License will not have their
licenses terminated so long as they remain in full compliance.

\stepcounter{v2section}
\section{\sout{Not a Contract} \textbf{Acceptance Not Required for
 Having Copies.}}

  You are not required to accept this License in order to receive
\textbf{or run} a copy of the Program.  \textbf{Ancillary propagation of
a covered work occurring solely as a consequence of using peer-to-peer
transmission to receive a copy likewise does not require acceptance.}
However, nothing else grants you permission to propagate or modify the
Program or any covered works.  These actions infringe copyright if you
do not accept this License.  Therefore, by modifying or propagating the
Program (or any covered work), you indicate your acceptance of this
License to do so, and all its terms and conditions.

\stepcounter{v2section}
\section{Automatic Licensing of Downstream Users.}

  Each time you \sout{redistribute} \textbf{convey} a covered work, the
recipient automatically receives a license from the original licensors,
to \sout{propagate and} \textbf{run,} modify \textbf{and propagate} that
work, subject to this License, including any additional terms introduced
through section 7.  You may not impose any further restrictions on the
recipients' exercise of the rights thus granted or affirmed, except
\sout{(when modifying the work)} in the limited ways permitted by
section 7.  \textbf{Therefore, you may not impose a license fee,
royalty, or other charge for exercise of rights granted under this
License.} You are not responsible for enforcing compliance by third
parties to this License.

\textbf{If propagation results from a transaction transferring control
of an organization, each party to that transaction who receives a copy
of the work also receives a license and a right to possession of the
Corresponding Source of the work from the party's predecessor in
interest.}

\renewcommand{\thesection}{\arabic{section}.}
\section{\sout{Licensing of} Patents.}

\sout{When you distribute a covered work, you grant a patent license to
the recipient, and to anyone that receives any version of the work,
permitting, for any and all versions of the covered work, all activities
allowed or contemplated by this License, such as installing, running and
distributing versions of the work, and using their output. This patent
license is nonexclusive, royalty-free and worldwide, and covers all
patent claims you control or have the right to sublicense, at the time
you distribute the covered work or in the future, that would be
infringed or violated by the covered work or any reasonably contemplated
use of the covered work.}

\textbf{You receive the Program with a covenant from each author and
conveyor of the Program, and of any material, conveyed under this
License, on which the Program is based, that the covenanting party will
not assert (or cause others to assert) any of the party's essential
patent claims in the material that the party conveyed, against you,
arising from your exercise of rights under this License.  If you convey
a covered work, you similarly covenant to all recipients, including
recipients of works based on the covered work, not to assert any of your
essential patent claims in the covered work.}

If you \sout{distribute} \textbf{convey} a covered work\textbf{,}
knowingly relying on a \textbf{non-sublicensable} patent license
\textbf{that is not generally available to all}, you must \textbf{either
(1)} act to shield downstream users against the possible patent
infringement claims from which your license protects you\textbf{, or (2)
ensure that anyone can copy the Corresponding Source of the covered
work, free of charge and under the terms of this License, through a
publicly-available network server or other readily accessible
means}.

\textbf{Nothing in this License shall be construed as excluding or
limiting any implied license or other defenses to infringement that may
otherwise be available to you under applicable patent
law.}

\section{\sout{Liberty or Death for the Program} \textbf{No Surrender 
of Others' Freedom.}}

If conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
\sout{distribute} \textbf{convey} the Program, or other covered work, so
as to satisfy simultaneously your obligations under this License and any
other pertinent obligations, then as a consequence you may not
\sout{distribute} \textbf{convey} it at all. For example, if \textbf{you
accept} a patent license \sout{would not permit} \textbf{that prohibits}
royalty-free \sout{redistribution} \textbf{conveying} by \sout{all}
those who receive copies directly or indirectly through you, then the
only way you could satisfy both it and this License would be to refrain
entirely from \sout{distribution} \textbf{conveying the
Program}.

\sout{It is not the purpose of this section to induce you to infringe
any patents or other exclusive rights or to contest their legal
validity.  The sole purpose of this section is to protect the integrity
of the free software distribution system. Many people have made generous
contributions to the wide range of software distributed through that
system in reliance on consistent application of that system; it is up to
the author/donor to decide if he or she is willing to distribute
software through any other system and a licensee cannot impose that
choice.}

\section{Geographical Limitations.}

  If the \sout{distribution} \textbf{conveying} and/or use of the
Program is restricted in certain countries either by patents or by
copyrighted interfaces, the original copyright holder who places the
Program under this License may add an explicit geographical
\sout{distribution} limitation \textbf{on conveying,} excluding those
countries, so that \sout{distribution} \textbf{conveying} is permitted
only in or among countries not thus excluded.  In such case, this
License incorporates the limitation as if written in the body of this
License.]

\section{Revised Versions of this License.}

  The Free Software Foundation may publish revised and/or new versions
of the GNU General Public License from time to time.  Such new versions
will be similar in spirit to the present version, but may differ in
detail to address new problems or concerns.

Each version is given a distinguishing version number.  If the Program
specifies that a certain numbered version of this License ``or any later
version'' applies to it, you have the option of following the terms and
conditions either of that numbered version or of any later version
published by the Free Software Foundation.  If the Program does not
specify a version number of this License, you may choose any version
ever published by the Free Software Foundation.

\section{Requesting Exceptions.}

  If you wish to incorporate parts of the Program into other free
programs \sout{whose distribution conditions are different}
\textbf{under other licenses}, write to the author to ask for
permission.  For software which is copyrighted by the Free Software
Foundation, write to the Free Software Foundation; we sometimes make
exceptions for this.  Our decision will be guided by the two goals of
preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.]

\section{\textbf{Disclaimer of Warranty.}}

  There is no warranty for the Program, to the extent permitted by
applicable law.  Except when otherwise stated in writing the copyright
holders and/or other parties provide the Program ``as is'' without
warranty of any kind, either expressed or implied, including, but not
limited to, the implied warranties of merchantability and fitness for a
particular purpose.  The entire risk as to the quality and performance
of the Program is with you.  Should the Program prove defective, you
assume the cost of all necessary servicing, repair or correction.

\section{\textbf{Limitation of Liability.}}

  In no event unless required by applicable law or agreed to in writing
will any copyright holder, or any other party who may modify and/or
\sout{redistribute} \textbf{convey} the Program as permitted above, be
liable to you for damages, including any general, special, incidental or
consequential damages arising out of the use or inability to use the
Program (including but not limited to loss of data or data being
rendered inaccurate or losses sustained by you or third parties or a
failure of the Program to operate with any other programs), even if such
holder or other party has been advised of the possibility of such
damages.
