\section*{Preamble}

  \textbf{The GNU General Public License is a free, copyleft license for
software and other kinds of works.}

  The licenses for most software \textbf{and other practical works} are
designed to take away your freedom to share and change \sout{it}
\textbf{the works}.  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.  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, 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.
Therefore, you have certain responsibilities 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 \sout{give} \textbf{pass on to} the
recipients \sout{all} the \textbf{same} \sout{rights} \textbf{freedoms}
that you \sout{have} \textbf{received}.  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 authors' protection, the GPL clearly explains
that there is no warranty for this free software.  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 \sout{original version} \textbf{previous versions}.

  Some \sout{computers} \textbf{devices} are designed to deny users
access to install or run modified versions of the software inside
them\textbf{, although the manufacturer can do so}.  This is
fundamentally incompatible with the purpose of the GPL, which is to
protect users' freedom to change the software \textbf{where changes are
possible}.  \textbf{The systematic pattern of such abuse occurs in the
area of products for individuals to use, which is precisely where it is
most unacceptable.}  Therefore, \sout{the GPL ensures that the software
it covers will not be restricted in this way} \textbf{we have designed
this version of the GPL to prohibit the practice for those products}.
\textbf{If such problems arise substantially in other domains, we stand
ready to extend this provision to those domains in future versions of
the GPL, as needed to protect the freedom of users.}

  Finally, every program is threatened constantly by software patents.
States should not allow patents to restrict development and use of
software on general-purpose computers, but in places where they do, we
wish to avoid the special danger that \sout{redistributors of}
\textbf{patents applied to} a free program \sout{will individually
obtain patent licenses, in effect making the program} \textbf{could make
it effectively} proprietary.  To prevent this, the GPL assures that
patents cannot be used to render the program non-free.

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

\ordsec{Definitions.}

  \textbf{``This License'' refers to version 3 of the GNU General Public
License.}

  \textbf{``Copyright'' also means copyright-like laws that apply to
other kinds of works, such as semiconductor masks.}

  \sout{In this License, each licensee is addressed as ``you,'' while
``the} \textbf{``The} Program'' refers to any \textbf{copyrightable}
work \sout{of authorship} licensed under this License.  \textbf{Each
licensee is addressed as ``you.''  ``Licensees'' and ``recipients'' may
be individuals or organizations.}

\sout{A ``modified'' work includes, without limitation, versions in
which mate\-rial has been translated or added. A work ``based
on''another work means any modified version, formation of which requires
permission under applica\-ble copyright law.} \textbf{To ``modify'' a
work means to copy from or adapt all or part of the work in a fashion
requiring copyright permission, other than the making of a verbatim
copy.  The resulting work is called a ``modified version'' of the
earlier work or a work ``based on'' the earlier work.}  A ``covered
work'' means either the unmodified Program or a work based on the
Program.

\textbf{A ``contributor'' is a party who licenses under this License a
work on which the Program is based.  Such a work is called the party's
``contribution.''}

  To ``propagate'' a work means \sout{doing} \textbf{to do (or cause
others to do)} anything with it that requires permission under
applicable copyright law, except executing it on a computer\sout{,} or
making modifications that you do not share.  Propagation includes
copying, distribution (with or without modification), making available
to the public, and in some countries other activities as well.  To
``convey'' a work means any kind of propagation that enables other
parties to make or receive copies, excluding sublicensing. \textbf{Mere
interaction with a user through a computer network, with no transfer of
a copy, is not conveying.}

  A party's ``essential patent claims'' in a work are all patent claims
\sout{that the party can give permission to practice} \textbf{owned or
controlled by the party}, whether already acquired or \sout{to be}
\textbf{hereafter} acquired, that would be infringed by \textbf{some
manner, permitted by this License, of} making, using, or selling the
work\textbf{, but do not include claims that would be infringed only as
a consequence of further modification of the work}.  \textbf{For
purposes of this definition, ``control'' includes the right to grant
sublicenses in a manner consistent with the requirements of this
License.}


\ordsec{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
\sout{version} \textbf{form} of a work.

  \textbf{A ``Standard Interface'' means an interface that either is an
official standard defined by a recognized standards body, or, in the
case of interfaces specified for a particular programming language, one
that is widely used among developers working in that
language.}

   The ``System Libraries'' of an executable work include \sout{every
subunit such} \textbf{anything, other than the work as a whole,} that
(a) \sout{the identical subunit} is normally included \sout{as an
adjunct} in the distribution of \sout{either} a \sout{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}
\textbf{Major Component}, \textbf{but which is not part of that Major
Component,} and (b) \sout{the subunit (aside from possible incidental
extensions)} serves only to enable use of the work with that
\sout{system component or compiler or interpreter} \textbf{Major
Component}, or to implement a \sout{widely used or standard interface}
\textbf{Standard Interface} for which an implementation is available to
the public in source code form.  \textbf{A ``Major Component'', in this
context, means a major essential component (kernel, window system, and
so on) of the specific operating system (if any) on which the executable
work runs, or a compiler used to produce the work, or an object code
interpreter used to run it.}

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

\sout{The Corresponding Source also includes any encryption or
authorization keys necessary to install and/or execute modified versions
from source code in the recommended or principal context of use, such
that they can implement all the same functionality in the same range of
circumstances.  (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.)  A
key need not be included in cases where use of the work normally implies
the user already has 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.}

  \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.}

  The Corresponding Source need not include anything that users can
regenerate automatically from other parts of the Corresponding Source.

  \textbf{The Corresponding Source for a work in source code form is
that same work.}


\ordsec{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 unmodified Program. The output from running
\sout{it} \textbf{a covered work} is covered by this License only if the
output, given its content, constitutes a covered work.  This License
acknowledges your rights of \sout{``}fair use\sout{''} or other
equivalent, as provided by copyright law.

  \sout{This License permits you to make and run privately modified
versions of the Program, or have others make and run them on your
behalf. However, this permission terminates, as to all such versions, if
you bring suit against anyone for patent infringement of any of your
essential patent claims in any such version, for making, using, selling
or otherwise conveying a work based on the Program in compliance with
this License.}

  Propagation of covered works \sout{other than conveying} \textbf{that
you do not convey, and making modified versions of the Program that you
do not convey,} \sout{is} \textbf{are} permitted without
\sout{limitation} \textbf{conditions, so long as your license otherwise
remains in force}. \textbf{Conveying is permitted under the conditions
stated below.}  Sublicensing is not allowed; section 10 makes it
unnecessary.  \sout{Conveying is permitted under the conditions stated
below.}


\ordsec{No Denying Users' Rights through Technical Measures.}

\sout{Regardless of any other provision of this License, no permission
is given for modes of conveying that deny users that run covered works
the full exercise of the legal rights granted by this
License.}

  No covered work \sout{constitutes} \textbf{shall be deemed} part of an
effective technological \sout{``protection''} measure under
\sout{section 1201 of Title 17 of the United States Code} \textbf{any
applicable law fulfilling obligations under article 11 of the WIPO
copyright treaty adopted on 20 December 1996, or similar laws
prohibiting or restricting circumvention of such measures}.

  When you convey a covered work, you waive any legal power to forbid
circumvention of technical measures \sout{that include use of}
\textbf{to the extent such circumvention is effected by exercising
rights under this License with respect to} the covered work, and you
disclaim any intention to limit operation or modification of the work as
a means of enforcing\textbf{, against the work's users, your or third
parties'} \sout{the} legal rights \sout{of third parties against the
work's users} \textbf{to forbid circumvention of technical
measures}.


\bracketsec{\textbf{Conveying} Verbatim \sout{Copying} \textbf{Copies}.}

  You may \sout{copy and} 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 \sout{license} notices \textbf{stating that this License
and any non-permissive terms added in accord with section 7 apply to the
code;} \sout{and} \textbf{keep intact all} notices of the absence of any
warranty; and give all recipients\sout{, along with the Program,} a copy
of this License \textbf{along with the Program} \sout{and the central
list (if any) required by section 7}. \sout{The recipients of these
copies will possess all the rights granted by this License (with any
added terms under section 7).}

  You may charge any price or no price for each copy that you convey,
and you may offer support or warranty protection for a fee.


\bracketsec{Conveying Modified Source Versions.}

  You may \sout{copy and} convey a work 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{\labelenumi}{\alph{enumi})}
\begin{enumerate}

\item

The \sout{modified} work must carry prominent notices stating that you
\sout{changed the work} \textbf{modified it,} and \sout{the date of any
change} \textbf{giving a relevant date}.

\renewcommand{\labelenumi}{\textbf{\alph{enumi})}}

\item 

\textbf{The work must carry prominent notices stating that it is
released under this License and any conditions added under section
7. This requirement modifies the requirement in section 4 to ``keep
intact all notices''.}

\setcounter{enumi}{1}
\renewcommand{\labelenumi}{\sout{\alph{enumi}} \stepcounter{enumi}\textbf{\alph{enumi}})}

\item

You must license the entire work, as a whole, under this License to
anyone who comes into possession of a copy.  This License \sout{must}
\textbf{will therefore} apply, unmodified except as permitted by section
7 \sout{below}, to the whole of the work, 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.

\setcounter{enumi}{2}
\item

If the \sout{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
\sout{program} \textbf{work} (\sout{or that} \textbf{unless} you provide
a warranty), that \sout{users} \textbf{licensees} may convey the
\sout{modified} work under this License, and how to view a copy of this
License \sout{together with the central list (if any) of other terms in
accord with section 7}.  Specifically, 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; otherwise, the
\sout{modified} work must display this information at startup.  However,
if the Program has interactive interfaces that do not comply with this
subsection, your \sout{modified} work need not make them comply.

\end{enumerate}

\sout{To the extent that identifiable sections of 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 convey
them as separate works, not specifically for use in combination with 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 compilation and its resulting copyright are not
used to limit the access or legal rights of the compilation's users
beyond what the individual works permit.  Inclusion of a covered work in
an aggregate does not cause this License to apply to the other parts of
the aggregate.


\bracketsec{Conveying Non-Source Forms.}

  You may \sout{copy and} convey a covered work in object code form
under the terms of sections 4 and 5, provided that you also convey the
machine-readable Corresponding Source under the terms of this License,
in one of these ways:

\begin{enumerate}

\renewcommand{\labelenumi}{\alph{enumi})}

\item 

Convey the object code in\textbf{, or embodied in,} a physical product
(including a physical distribution medium), accompanied by the
Corresponding Source fixed on a durable physical medium customarily used
for software interchange.

\item 

Convey the object code in\textbf{, or embodied 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, \textbf{either
(1)} to give \sout{any third party} \textbf{anyone who possesses the
object code} 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, for a price no more
than your reasonable cost of physically performing this conveying of
source\sout{.}\textbf{, or (2)}

\renewcommand{\labelenumi}{\sout{[\alph{enumi}1)}}
\setcounter{enumi}{1}

\item 

\sout{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.\sout{]}

\renewcommand{\labelenumi}{\alph{enumi})}

\item Convey individual copies of the object code with a copy of the
written offer to provide the Corresponding Source.  This alternative is
allowed only occasionally and noncommercially, and only if you received
the object code with such an offer, in accord with subsection 6b
\sout{or 6b1}.

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

\sout{[}If the place to copy the object code is a network server, the
Corresponding Source may be on a different server \textbf{(operated by
you or a third party)} that supports equivalent copying facilities,
\sout{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 object code saying where to find the
Corresponding Source.\sout{]} \textbf{Regardless of what server hosts
the Corresponding Source, you remain obligated to ensure that it is
available for as long as needed to satisfy these
requirements.}

\item Convey the object code using peer-to-peer transmission\textbf{,}
provided you \sout{know that, and} inform other peers where\sout{,} 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{The Corresponding Source conveyed in accord with this section
must be in a format that is publicly documented, with an implementation
available to the public in source code form, and must require no special
password or key for unpacking, reading or copying.}

  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.

\textbf{A ``User Product'' is either (1) a ``consumer product'', which
means any tangible personal property which is normally used for
personal, family, or household purposes, or (2) anything designed or
sold for incorporation into a dwelling. [In cases of doubt concerning
whether an item is a ``consumer product'', the interpretation of the
Magnuson-Moss Warranty Act, 15 U.S.C. \S\ 2301 \textit{et seq.}, shall
provide the basis for interpretation, regardless of the choice of law
determination for this License as a whole.]}

\textbf{``Installation Information'' for a User Product means any
methods, procedures, authorization keys, or other information required
to install and execute modified versions of a covered work in that User
Product from a modified version of its Corresponding Source. The
information must suffice to ensure that the continued functioning of the
modified object code is in no case prevented or interfered with solely
because modification has been made.}

\textbf{If you convey an object code work under this section in, or
with, or specifically for use in, a User Product, and the conveying
occurs as part of a transaction in which the right of possession and use
of the User Product is transferred to the recipient in perpetuity or for
a fixed term (regardless of how the transaction is characterized), the
Corresponding Source conveyed under this section must be accompanied by
the Installation Information.  But this requirement does not apply if
neither you nor any third party retains the ability to install modified
object code on the User Product (for example, the work has been
installed in ROM).}

  \textbf{The requirement to provide Installation Information does not
include a requirement to continue to provide support service, warranty,
or updates for a work that has been modified or installed by the
recipient.  Network access may be denied when the modification itself
materially and adversely affects the operation of the network or
violates the rules and protocols for communication across the
network.}

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


\ordsec{Additional Terms.}

  \sout{You may have received the Program, or parts of it, under terms
that\linebreak supplement the terms of this License.  These additional
terms may include additional permissions, as provided in subsection 7a,
and additional\linebreak 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}\sout{\alph{subsection}.}\hspace{-5pt}}

\subsection{\sout{Additional Permissions.}}

\textbf{``}Additional permissions\textbf{''} \textbf{are terms that
supplement the terms of this License by} \sout{make} \textbf{making}
exceptions from one or more of \sout{the requirements of this License}
\textbf{its conditions}.  \sout{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.}

\sout{Any additional} \textbf{Additional} permissions that are
applicable to the entire Program shall be treated as though they were
included in this License, \sout{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 \sout{terms}
\textbf{permissions}.


\subsection{\sout{Additional Requirements.}}

  \sout{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}{\sout{\arabic{enumi})}}
\begin{enumerate}
\setcounter{enumi}{-1}
\item \sout{terms that require preservation of specified reasonable
      legal notices or author attributions;} \sout{or}

\item \sout{terms that require that the origin of the material they
      cover not be misrepresented, or that modified versions of that
      material be marked in specific reasonable ways as different from
      the original version;} \sout{or}

\item \sout{warranty or liability disclaimers that differ from the
      disclaimers in this License;} \sout{or}

\item \sout{terms that prohibit or limit the use for publicity purposes
      of specified names of licensors or authors, or that require that
      certain specified trade names, trademarks, or service marks not be
      used for publicity purposes without express permission, other than
      in ways that are fair use under applicable trademark law;}
      \sout{or}

\item \sout{terms that require, if a modified version of the material
      they cover is a work intended to interact with users through a
      computer network, that those users be able to obtain copies of the
      Corresponding Source of the work through the same network
      session;} \sout{or}

\item \sout{terms that wholly or partially terminate, or allow
      termination of, permission for use of the material they cover, for
      a user who files a software patent lawsuit (that is, a lawsuit
      alleging that some software infringes a patent) 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;} \sout{or}

\item \sout{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}

\noindent \sout{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{\sout{Terms Added or Removed by You.}}

  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.  \textbf{(}\sout{Some additional} \textbf{Additional} permissions
\textbf{may be written to} require their own removal in certain cases
when you modify the work.\textbf{)} \textbf{You may place additional
permissions on material, added by you to a covered work, for which you
have or can give appropriate copyright permission.}

\textbf{Notwithstanding any other provision of this License, you may
supplement the terms of this License with terms effective under, or
drafted for compatibility with, local law:}

\renewcommand{\labelenumi}{\textbf{\alph{enumi}.}}
\begin{enumerate}

\item \textbf{disclaiming warranty or limiting liability differently
      from the terms of section 15 of this License;} \textbf{or}

\item \textbf{requiring preservation of specified reasonable legal
      notices or author attributions in source or object code forms of
      material added by you to a covered work;} \textbf{or}
 
\item \textbf{prohibiting misrepresentation of the origin of material
      added by you to a covered work, or requiring that modified
      versions of such material be marked in reasonable ways as
      different from the original version;} \textbf{or}

\item \textbf{limiting the use for publicity purposes of specified names
      of licensors or authors, or of specified trade names, trademarks,
      or service marks, to the extent otherwise permitted by
      law.}

\end{enumerate}

  \sout{Additional requirements are allowed only as stated in subsection
7b.}  \textbf{All other non-permissive additional terms are considered
``further restrictions'' within the meaning of section 10.}  If the
Program as you received it\textbf{, or any part of it,} purports to
\sout{impose any other additional requirement} \textbf{be governed by
this License, supplemented by a term that is a further restriction}, you
may remove that \sout{requirement} \textbf{term}.  \textbf{If a license
document contains a further restriction but permits relicensing or
conveying under this License, you may add to a covered work material
governed by the terms of that license document, provided that the
further restriction does not survive such relicensing or
conveying.}

\sout{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.}
\sout{Adding requirements not allowed by subsection 7b is a violation of
this License that may lead to termination of your rights under section
8.}

  If you add terms to a covered work in accord\sout{ance} 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.


\bracketsec{Termination.}

  You may not propagate or modify \sout{the Program} \textbf{a covered
work} except as expressly provided under this License.  Any attempt
otherwise to propagate or modify \sout{the Program} \textbf{it} is void.
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 \sout{last} \textbf{most recent}
violation.  Having put you on notice, the copyright holder may\textbf{,}
\sout{then terminate your license} at any time\textbf{, terminate the
rights (including any patent rights) that the copyright holder has
granted to you under this License}.

\textbf{However, if this is your first violation of this License with
respect to a given copyright holder, and you cure the violation within
30 days following your receipt of the notice, then your license is
automatically reinstated.}

\sout{However,} \textbf{In the event that your rights are terminated
under this section,} 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.


\bracketsec{Acceptance Not Required for Having Copies.}

  You are not required to accept this License in order to receive or run
a copy of the Program.  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
\sout{else} \textbf{other than this License} grants you permission to
propagate or modify \sout{the Program or} any covered \sout{works}
\textbf{work}. These actions infringe copyright if you do not accept
this License.  Therefore, by modifying or propagating \sout{the Program
(or any} \textbf{a} covered work\sout{)}, you indicate your acceptance
of this License to do so\sout{, and all its terms and
conditions}.


\bracketsec{Automatic Licensing of Downstream \sout{Users}
 \textbf{Recipients}.}

  Each time you convey a covered work, the recipient automatically
receives a license from the original licensors, to run, modify and
propagate that work, subject to this License\sout{, including any
additional terms introduced through section 7}.  \sout{You may not
impose any further restrictions on the recipients' exercise of the
rights thus granted or affirmed, except in the limited ways permitted by
section 7.  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 \sout{to}
\textbf{with} this License.

  \textbf{An ``entity transaction'' is a transaction transferring
control of an organization, or substantially all assets of one, or
subdividing an organization, or merging organizations.}  If propagation
\textbf{of a covered work} results from \sout{a transaction transferring
control of an organization} \textbf{an entity transaction}, each party
to that transaction who receives a copy of the work also receives
\sout{a license} \textbf{whatever licenses to the work the party's
predecessor in interest had or could give under the previous paragraph,
plus} \sout{and} a right to possession of the Corresponding Source of
the work from the \sout{party's} predecessor in interest.

\textbf{You may not impose any further restrictions on the exercise of
the rights granted or affirmed under this License.  For example, you may
not impose a license fee, royalty, or other charge for exercise of
rights granted under this License, and you may not initiate litigation
(including a cross-claim or counterclaim in a lawsuit) alleging that any
patent claim is infringed by making, using, selling, offering for sale,
or importing the Program (or the contribution of any
contributor).}


\ordsec{Patents.}

\sout{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.}

\textbf{Each contributor grants you a non-exclusive, worldwide,
royalty-free patent license under the contributor's essential patent
claims in its contribution, to make, use, sell, offer for sale, import
and otherwise run, modify and propagate the contribution.}

\textbf{For purposes of the following three paragraphs, a ``patent
license'' means a patent license, a covenant not to bring suit for
patent infringement, or any other express agreement or commitment,
however denominated, not to enforce a patent.}

If you convey a covered work, knowingly relying on a
\sout{non-sublicensable} patent license \sout{that is not generally
available to all}, \textbf{and the Corresponding Source of the work is
not available for anyone to copy, free of charge and under the terms of
this License, through a publicly available network server or other
readily accessible means, then} you must either \sout{(1) act to shield
downstream users against the possible patent infringement claims from
which your license protects you, 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{(1) cause the Corresponding
Source to be so available, or (2) disclaim the patent license for this
particular work, or (3) arrange, in a manner consistent with the
requirements of this License, to extend the patent license to downstream
recipients}. \textbf{``Knowingly relying'' means you have actual
knowledge that, but for the patent license, your conveying the covered
work in a country, or your recipient's use of the covered work in a
country, would infringe one or more identifiable patents in that country
that you have reason to believe are valid.}

\textbf{If, pursuant to or in connection with a single transaction or
arrangement, you convey, or propagate by procuring conveyance of, a
covered work, and grant a patent license providing freedom to use,
propagate, modify or convey a specific copy of the covered work to any
of the parties receiving the covered work, then the patent license you
grant is automatically extended to all recipients of the covered work
and works based on it.}

\textbf{You may not convey a covered work if you are a party to an
arrangement with a third party that is in the business of distributing
software, under which you make payment to the third party based on the
extent of your activity of conveying the work, and under which the third
party grants, to any of the parties who would receive the covered work
from you, a patent license (a) in connection with copies of the covered
work conveyed by you, and/or copies made from those, or (b) primarily
for and in connection with specific products or compilations that
contain the covered work, which license does not cover, prohibits the
exercise of, or is conditioned on the non-exercise of any of the rights
that are specifically granted to recipients of the covered work under
this License[, unless you entered into that arrangement, or that patent
license was granted, prior to March 28, 2007].}

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.


\bracketsec{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 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 convey it at all.  For example, if you
\sout{accept a patent license that prohibits royalty-free conveying by
those who receive copies directly or indirectly through you}
\textbf{agree to terms that obligate you to collect a royalty for
further conveying from those to whom you convey the Program},
\sout{then} the only way you could satisfy both \sout{it} \textbf{those
terms} and this License would be to refrain entirely from conveying the
Program.

\section{\textbf{Use with the Affero General Public License.}}

\textbf{Notwithstanding any other provision of this License, you have
permission to link any covered work with a work licensed under version 2
of the Affero General Public License, and to convey the resulting
combination.  The terms of this License will continue to apply to your
covered work but will not apply to the work with which it is linked,
which will remain governed by the Affero General Public
License.}

\delsec{[}{Geographical Limitations.}{}

 \sout{If the 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 limitation on conveying, excluding those
countries, so that 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.]}


\bracketsec{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 \sout{this} \textbf{the GNU
General Public} 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
\sout{this} \textbf{the GNU General Public} License, you may choose any
version ever published by the Free Software Foundation.

  \textbf{If the Program specifies that a proxy can decide whether
future versions of the GNU General Public License shall apply, that
proxy's public statement of acceptance of any version is permanent
authorization for you to choose that version for the
Program.}


\delsec{}{Requesting Exceptions.}{}

  \sout{If you wish to incorporate parts of the Program into other free
programs 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{Disclaimer of Warranty \textbf{and Limitation of Liability}.}

  \sout{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 war\-ranties 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.}

\noindent \textbf{THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT
PERMITTED BY APPLICABLE LAW.  EXCEPT \linebreak WHEN OTHERWISE STATED IN
WRITING THE COPY- \linebreak RIGHT 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 MER-
\linebreak CHANTABILITY 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.}


\delsec{}{Limitation of Liability.}{}

  \sout{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 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.}

  \textbf{IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
WRITING WILL ANY COPYRIGHT \linebreak HOLDER, OR ANY OTHER PARTY WHO
MODIFIES AND/ OR CONVEYS 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 \linebreak
SUCH DAMAGES.}

  \textbf{If the disclaimer of warranty and limitation of liability
provided above cannot be given local legal effect according to their
terms, reviewing courts shall apply local law that most closely
approximates an absolute waiver of all civil liability in connection
with the Program, unless a warranty or assumption of liability
accompanies a copy of the Program in return for a fee.}
