+\subsection{Which License Applies?}
+
+Different parts of the \pgfname\ package are distributed under different
+licenses:
+%
+\begin{enumerate}
+ \item The \emph{code} of the package is dual-license. This means that you
+ can decide which license you wish to use when using the \pgfname\
+ package. The two options are:
+ %
+ \begin{enumerate}
+ \item You can use the \textsc{gnu} Public License, version 2.
+ \item You can use the \LaTeX\ Project Public License, version
+ 1.3c.
+ \end{enumerate}
+ \item The \emph{documentation} of the package is also dual-license.
+ Again, you can choose between two options:
+ %
+ \begin{enumerate}
+ \item You can use the \textsc{gnu} Free Documentation License,
+ version 1.2.
+ \item You can use the \LaTeX\ Project Public License, version
+ 1.3c.
+ \end{enumerate}
+\end{enumerate}
+
+The ``documentation of the package'' refers to all files in the subdirectory
+|doc| of the |pgf| package. A detailed listing can be found in the file
+|doc/generic/pgf/licenses/manifest-documentation.txt|. All files in other
+directories are part of the ``code of the package''. A detailed listing can be
+found in the file |doc/generic/pgf/licenses/manifest-code.txt|.
+
+In the rest of this section, the licenses are presented. The following text is
+copyrighted, see the plain text versions of these licenses in the directory
+|doc/generic/pgf/licenses| for details.
+
+The example picture used in this manual, the Brave \textsc{gnu} World logo, is
+taken from the Brave \textsc{gnu} World homepage, where it is copyrighted as
+follows: ``Copyright (C) 1999, 2000, 2001, 2002, 2003, 2004 Georg C.~F.\ Greve.
+Permission is granted to make and distribute verbatim copies of this transcript
+as long as the copyright and this permission notice appear.''
+
+
+\subsection{The GNU Public License, Version 2}
+
+\subsubsection{Preamble}
+
+The licenses for most software are designed to take away your freedom to share
+and change it. By contrast, the \textsc{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. This General Public License
+applies to most of the Free Software Foundation's software and to any other
+program whose authors commit to using it. (Some other Free Software Foundation
+software is covered by the \textsc{gnu} Library 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; and that you know you
+can do these things.
+
+To protect your rights, we need to make restrictions that forbid anyone to deny
+you these rights or to ask you to surrender the rights. These restrictions
+translate to certain responsibilities 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.
+
+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.
+
+
+\subsubsection{Terms and Conditions For Copying, Distribution and Modification}
+
+\begin{enumerate}
+ \addtocounter{enumi}{-1}
+ \item 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.
+ \item 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.
+ \item 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:
+ %
+ \begin{enumerate}
+ \item You must cause the modified files to carry prominent
+ notices stating that you changed the files and the date of
+ any change.
+ \item 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.
+ \item 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.)
+ \end{enumerate}
+ %
+ 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.
+ \item 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:
+ %
+ \begin{enumerate}
+ \item 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,
+ \item 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,
+ \item 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
+ Subsubsection~b above.)
+ \end{enumerate}
+ %
+ 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.
+ \item You may not copy, modify, sublicense, or distribute the Program
+ except as expressly provided under this License. Any attempt
+ otherwise to copy, modify, sublicense or distribute the Program is
+ void, and will automatically terminate your rights under this
+ License. However, parties who have received copies, or rights, from
+ you under this License will not have their licenses terminated so
+ long as such parties remain in full compliance.
+ \item You are not required to accept this License, since you have not
+ signed it. However, nothing else grants you permission to modify or
+ distribute the Program or its derivative works. These actions are
+ prohibited by law if you do not accept this License. Therefore, by
+ modifying or distributing the Program (or any work based on the
+ Program), you indicate your acceptance of this License to do so, and
+ all its terms and conditions for copying, distributing or modifying
+ the Program or works based on it.
+ \item Each time you redistribute the Program (or any work based on the
+ Program), the recipient automatically receives a license from the
+ original licensor to copy, distribute or modify the Program subject
+ to these terms and conditions. You may not impose any further
+ restrictions on the recipients' exercise of the rights granted
+ herein. You are not responsible for enforcing compliance by third
+ parties to this License.
+ \item If, as a consequence of a court judgment or allegation of patent
+ infringement or for any other reason (not limited to patent issues),
+ 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
+ distribute so as to satisfy simultaneously your obligations under
+ this License and any other pertinent obligations, then as a
+ consequence you may not distribute the Program at all. For example,
+ if a patent license would not permit royalty-free redistribution of
+ the Program by 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 distribution of the
+ Program.
+
+ If any portion of this section is held invalid or unenforceable under
+ any particular circumstance, the balance of the section is intended
+ to apply and the section as a whole is intended to apply in other
+ circumstances.
+
+ It is not the purpose of this section to induce you to infringe any
+ patents or other property right claims or to contest validity of any
+ such claims; this section has the sole purpose of protecting the
+ integrity of the free software distribution system, which is
+ implemented by public license practices. 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.
+
+ This section is intended to make thoroughly clear what is believed to
+ be a consequence of the rest of this License.
+ \item If the distribution 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 distribution limitation excluding
+ those countries, so that distribution 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.
+ \item The Free Software Foundation may publish revised and/or new
+ versions of the 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 a version number of this License which applies to
+ it and ``any later version'', you have the option of following the
+ terms and conditions either of that 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.
+ \item If you wish to incorporate parts of the Program into other free
+ programs whose distribution conditions are different, 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.
+\end{enumerate}
+
+
+\subsubsection{No Warranty}
+
+\begin{enumerate}
+ \addtocounter{enumi}{9}
+ \item Because the program is licensed free of charge, 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.
+ \item 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 redistribute 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.

+
+ \LPPLsubsection{Preamble}
+ \label{LPPL:Preamble}
+
+ The \LaTeX\ Project Public License (\LPPL) is the primary license under
+ which the \LaTeX\ kernel and the base \LaTeX\ packages are distributed.
+
+ You may use this license for any work of which you hold the copyright and
+ which you wish to distribute. This license may be particularly suitable if
+ your work is \TeX-related (such as a \LaTeX\ package), but it is written in
+ such a way that you can use it even if your work is unrelated to \TeX.
+
+ The section `\textsc{whether and how to distribute works under this
+ license}', below, gives instructions, examples, and recommendations for
+ authors who are considering distributing their works under this license.
+
+ This license gives conditions under which a work may be distributed and
+ modified, as well as conditions under which modified versions of that work
+ may be distributed.
+
+ We, the \LaTeX3 Project, believe that the conditions below give you the
+ freedom to make and distribute modified versions of your work that conform
+ with whatever technical specifications you wish while maintaining the
+ availability, integrity, and reliability of that work. If you do not see
+ how to achieve your goal while meeting these conditions, then read the
+ document \LPPLdocfile{cfgguide} and \LPPLdocfile{modguide} in the base
+ \LaTeX\ distribution for suggestions.
+
+
+ \LPPLsubsection{Definitions}
+ \label{LPPL:Definitions}
+
+ In this license document the following terms are used:
+
+ \begin{description}
+ \item[Work] Any work being distributed under this License.
+ \item[Derived Work] Any work that under any applicable law is
+ derived from the Work.
+ \item[Modification] Any procedure that produces a Derived Work under
+ any applicable law -- for example, the production of a file
+ containing an original file associated with the Work or a
+ significant portion of such a file, either verbatim or with
+ modifications and/or translated into another language.
+ \item[Modify] To apply any procedure that produces a Derived Work
+ under any applicable law.
+ \item[Distribution] Making copies of the Work available from one
+ person to another, in whole or in part. Distribution includes (but
+ is not limited to) making any electronic components of the Work
+ accessible by file transfer protocols such as \textsc{ftp} or
+ \textsc{http} or by shared file systems such as Sun's Network File
+ System (\textsc{nfs}).
+ \item[Compiled Work] A version of the Work that has been processed
+ into a form where it is directly usable on a computer system.
+ This processing may include using installation facilities provided
+ by the Work, transformations of the Work, copying of components of
+ the Work, or other activities. Note that modification of any
+ installation facilities provided by the Work constitutes
+ modification of the Work.
+ \item[Current Maintainer] A person or persons nominated as such
+ within the Work. If there is no such explicit nomination then it
+ is the `Copyright Holder' under any applicable law.
+ \item[Base Interpreter] A program or process that is normally needed
+ for running or interpreting a part or the whole of the Work.
+
+ A Base Interpreter may depend on external components but these are
+ not considered part of the Base Interpreter provided that each
+ external component clearly identifies itself whenever it is used
+ interactively. Unless explicitly specified when applying the
+ license to the Work, the only applicable Base Interpreter is a
+ `\LaTeX-Format' or in the case of files belonging to the
+ `\LaTeX-format' a program implementing the `\TeX{} language'.
+ \end{description}
+
+
+ \LPPLsubsection{Conditions on Distribution and Modification}
+ \label{LPPL:Conditions}
+
+ \begin{enumerate}
+ \item Activities other than distribution and/or modification of the
+ Work are not covered by this license; they are outside its scope.
+ In particular, the act of running the Work is not restricted and
+ no requirements are made concerning any offers of support for the
+ Work.
+ \item\label{LPPL:item:distribute} You may distribute a complete,
+ unmodified copy of the Work as you received it. Distribution of
+ only part of the Work is considered modification of the Work, and
+ no right to distribute such a Derived Work may be assumed under the
+ terms of this clause.
+ \item You may distribute a Compiled Work that has been generated from
+ a complete, unmodified copy of the Work as distributed under
+ Clause~\ref{LPPL:item:distribute} above, as long as that Compiled
+ Work is distributed in such a way that the recipients may install
+ the Compiled Work on their system exactly as it would have been
+ installed if they generated a Compiled Work directly from the Work.
+ \item\label{LPPL:item:currmaint} If you are the Current Maintainer of
+ the Work, you may, without restriction, modify the Work, thus
+ creating a Derived Work. You may also distribute the Derived Work
+ without restriction, including Compiled Works generated from the
+ Derived Work. Derived Works distributed in this manner by the
+ Current Maintainer are considered to be updated versions of the
+ Work.
+ \item If you are not the Current Maintainer of the Work, you may modify
+ your copy of the Work, thus creating a Derived Work based on the
+ Work, and compile this Derived Work, thus creating a Compiled Work
+ based on the Derived Work.
+ \item\label{LPPL:item:conditions} If you are not the Current Maintainer
+ of the Work, you may distribute a Derived Work provided the
+ following conditions are met for every component of the Work unless
+ that component clearly states in the copyright notice that it is
+ exempt from that condition. Only the Current Maintainer is allowed
+ to add such statements of exemption to a component of the Work.
+ %
+ \begin{enumerate}
+ \item If a component of this Derived Work can be a direct
+ replacement for a component of the Work when that component
+ is used with the Base Interpreter, then, wherever this
+ component of the Work identifies itself to the user when
+ used interactively with that Base Interpreter, the
+ replacement component of this Derived Work clearly and
+ unambiguously identifies itself as a modified version of
+ this component to the user when used interactively with
+ that Base Interpreter.
+ \item Every component of the Derived Work contains prominent
+ notices detailing the nature of the changes to that
+ component, or a prominent reference to another file that is
+ distributed as part of the Derived Work and that contains a
+ complete and accurate log of the changes.
+ \item No information in the Derived Work implies that any
+ persons, including (but not limited to) the authors of the
+ original version of the Work, provide any support,
+ including (but not limited to) the reporting and handling
+ of errors, to recipients of the Derived Work unless those
+ persons have stated explicitly that they do provide such
+ support for the Derived Work.
+ \item You distribute at least one of the following with the
+ Derived Work:
+ %
+ \begin{enumerate}
+ \item A complete, unmodified copy of the Work; if your
+ distribution of a modified component is made by
+ offering access to copy the modified component from
+ a designated place, then offering equivalent access
+ to copy the Work from the same or some similar
+ place meets this condition, even though third
+ parties are not compelled to copy the Work along
+ with the modified component;
+ \item Information that is sufficient to obtain a
+ complete, unmodified copy of the Work.
+ \end{enumerate}
+ \end{enumerate}
+ %
+ \item If you are not the Current Maintainer of the Work, you may
+ distribute a Compiled Work generated from a Derived Work, as long
+ as the Derived Work is distributed to all recipients of the
+ Compiled Work, and as long as the conditions of
+ Clause~\ref{LPPL:item:conditions}, above, are met with regard to
+ the Derived Work.
+ \item The conditions above are not intended to prohibit, and hence do
+ not apply to, the modification, by any method, of any component so
+ that it becomes identical to an updated version of that component
+ of the Work as it is distributed by the Current Maintainer under
+ Clause~\ref{LPPL:item:currmaint}, above.
+ \item Distribution of the Work or any Derived Work in an alternative
+ format, where the Work or that Derived Work (in whole or in part)
+ is then produced by applying some process to that format, does not
+ relax or nullify any sections of this license as they pertain to
+ the results of applying that process.
+ \item \null
+ \begin{enumerate}
+ \item A Derived Work may be distributed under a different
+ license provided that license itself honors the conditions
+ listed in Clause~\ref{LPPL:item:conditions} above, in
+ regard to the Work, though it does not have to honor the
+ rest of the conditions in this license.
+ \item If a Derived Work is distributed under a different license,
+ that Derived Work must provide sufficient documentation as part
+ of itself to allow each recipient of that Derived Work to honor
+ the restrictions in Clause~\ref{LPPL:item:conditions} above,
+ concerning changes from the Work.
+ \end{enumerate}
+ %
+ \item This license places no restrictions on works that are unrelated
+ to the Work, nor does this license place any restrictions on
+ aggregating such works with the Work by any means.
+ \item Nothing in this license is intended to, or may be used to, prevent
+ complete compliance by all parties with all applicable laws.
+ \end{enumerate}
+
+
+ \LPPLsubsection{No Warranty}
+ \label{LPPL:Warranty}
+
+ There is no warranty for the Work. Except when otherwise stated in
+ writing, the Copyright Holder provides the Work `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 Work is
+ with you. Should the Work prove defective, you assume the cost of all
+ necessary servicing, repair, or correction.
+
+ In no event unless required by applicable law or agreed to in writing will
+ The Copyright Holder, or any author named in the components of the Work, or
+ any other party who may distribute and/or modify the Work as permitted
+ above, be liable to you for damages, including any general, special,
+ incidental or consequential damages arising out of any use of the Work or
+ out of inability to use the Work (including, but not limited to, loss of
+ data, data being rendered inaccurate, or losses sustained by anyone as a
+ result of any failure of the Work to operate with any other programs), even
+ if the Copyright Holder or said author or said other party has been advised
+ of the possibility of such damages.
+
+
+ \LPPLsubsection{Maintenance of The Work}
+ \label{LPPL:Maintenance}
+
+ The Work has the status `author-maintained' if the Copyright Holder
+ explicitly and prominently states near the primary copyright notice in the
+ Work that the Work can only be maintained by the Copyright Holder or simply
+ that it is `author-maintained'.
+
+ The Work has the status `maintained' if there is a Current Maintainer who
+ has indicated in the Work that they are willing to receive error reports
+ for the Work (for example, by supplying a valid e-mail address). It is not
+ required for the Current Maintainer to acknowledge or act upon these error
+ reports.
+
+ The Work changes from status `maintained' to `unmaintained' if there is no
+ Current Maintainer, or the person stated to be Current Maintainer of the
+ work cannot be reached through the indicated means of communication for a
+ period of six months, and there are no other significant signs of active
+ maintenance.
+
+ You can become the Current Maintainer of the Work by agreement with any
+ existing Current Maintainer to take over this role.
+
+ If the Work is unmaintained, you can become the Current Maintainer of the
+ Work through the following steps:
+ %
+ \begin{enumerate}
+ \item Make a reasonable attempt to trace the Current Maintainer (and
+ the Copyright Holder, if the two differ) through the means of an
+ Internet or similar search.
+ \item If this search is successful, then enquire whether the Work is
+ still maintained.
+ %
+ \begin{enumerate}
+ \item If it is being maintained, then ask the Current
+ Maintainer to update their communication data within one
+ month.
+ \item\label{LPPL:item:intention} If the search is unsuccessful
+ or no action to resume active maintenance is taken by the
+ Current Maintainer, then announce within the pertinent
+ community your intention to take over maintenance. (If the
+ Work is a \LaTeX{} work, this could be done, for example,
+ by posting to \texttt{comp.text.tex}.)
+ \end{enumerate}
+ %
+ \item {}
+ \begin{enumerate}
+ \item If the Current Maintainer is reachable and agrees to
+ pass maintenance of the Work to you, then this takes effect
+ immediately upon announcement.
+ \item\label{LPPL:item:announce} If the Current Maintainer is
+ not reachable and the Copyright Holder agrees that maintenance
+ of the Work be passed to you, then this takes effect
+ immediately upon announcement.
+ \end{enumerate}
+ %
+ \item\label{LPPL:item:change} If you make an `intention
+ announcement' as described in~\ref{LPPL:item:intention} above and
+ after three months your intention is challenged neither by the
+ Current Maintainer nor by the Copyright Holder nor by other people,
+ then you may arrange for the Work to be changed so as to name you
+ as the (new) Current Maintainer.
+ \item If the previously unreachable Current Maintainer becomes
+ reachable once more within three months of a change completed under
+ the terms of~\ref{LPPL:item:announce} or~\ref{LPPL:item:change},
+ then that Current Maintainer must become or remain the Current
+ Maintainer upon request provided they then update their
+ communication data within one month.
+ \end{enumerate}
+ %
+ A change in the Current Maintainer does not, of itself, alter the fact that
+ the Work is distributed under the \LPPL\ license.
+
+ If you become the Current Maintainer of the Work, you should immediately
+ provide, within the Work, a prominent and unambiguous statement of your
+ status as Current Maintainer. You should also announce your new status to
+ the same pertinent community as in~\ref{LPPL:item:intention} above.
+
+
+ \LPPLsubsection{Whether and How to Distribute Works under This License}
+ \label{LPPL:Distribute}
+
+ This section contains important instructions, examples, and recommendations
+ for authors who are considering distributing their works under this
+ license. These authors are addressed as `you' in this section.
+
+
+ \LPPLsubsubsection{Choosing This License or Another License}
+ \label{LPPL:Choosing}
+
+ If for any part of your work you want or need to use \emph{distribution}
+ conditions that differ significantly from those in this license, then do
+ not refer to this license anywhere in your work but, instead, distribute
+ your work under a different license. You may use the text of this license
+ as a model for your own license, but your license should not refer to the
+ \LPPL\ or otherwise give the impression that your work is distributed under
+ the \LPPL.
+
+ The document \LPPLdocfile{modguide} in the base \LaTeX\ distribution
+ explains the motivation behind the conditions of this license. It
+ explains, for example, why distributing \LaTeX\ under the \textsc{gnu}
+ General Public License (\textsc{gpl}) was considered inappropriate. Even
+ if your work is unrelated to \LaTeX, the discussion in
+ \LPPLdocfile{modguide} may still be relevant, and authors intending to
+ distribute their works under any license are encouraged to read it.
+
+
+ \LPPLsubsubsection{A Recommendation on Modification Without Distribution}
+ \label{LPPL:WithoutDistribution}
+
+ It is wise never to modify a component of the Work, even for your own
+ personal use, without also meeting the above conditions for distributing
+ the modified component. While you might intend that such modifications
+ will never be distributed, often this will happen by accident -- you may
+ forget that you have modified that component; or it may not occur to you
+ when allowing others to access the modified version that you are thus
+ distributing it and violating the conditions of this license in ways that
+ could have legal implications and, worse, cause problems for the community.
+ It is therefore usually in your best interest to keep your copy of the Work
+ identical with the public one. Many works provide ways to control the
+ behavior of that work without altering any of its licensed components.
+
+
+ \LPPLsubsubsection{How to Use This License}
+ \label{LPPL:HowTo}
+
+ To use this license, place in each of the components of your work both an
+ explicit copyright notice including your name and the year the work was
+ authored and/or last substantially modified. Include also a statement that
+ the distribution and/or modification of that component is constrained by
+ the conditions in this license.
+
+ Here is an example of such a notice and statement:
+ %
+\begin{verbatim}
+ %% pig.dtx
+ %% Copyright 2005 M. Y. Name
+ %
+ % This work may be distributed and/or modified under the
+ % conditions of the LaTeX Project Public License, either version 1.3
+ % of this license or (at your option) any later version.
+ % The latest version of this license is in
+ % http://www.latex-project.org/lppl.txt
+ % and version 1.3 or later is part of all distributions of LaTeX
+ % version 2005/12/01 or later.
+ %
+ % This work has the LPPL maintenance status `maintained'.
+ %
+ % The Current Maintainer of this work is M. Y. Name.
+ %
+ % This work consists of the files pig.dtx and pig.ins
+ % and the derived file pig.sty.
+\end{verbatim}
+
+ Given such a notice and statement in a file, the conditions given in this
+ license document would apply, with the `Work' referring to the three files
+ `\LPPLfile{pig.dtx}', `\LPPLfile{pig.ins}', and `\LPPLfile{pig.sty}' (the
+ last being generated from `\LPPLfile{pig.dtx}' using `\LPPLfile{pig.ins}'),
+ the `Base Interpreter' referring to any `\LaTeX-Format', and both
+ `Copyright Holder' and `Current Maintainer' referring to the person `M. Y.
+ Name'.
+
+ If you do not want the Maintenance section of \LPPL\ to apply to your Work,
+ change `maintained' above into `author-maintained'. However, we recommend
+ that you use `maintained' as the Maintenance section was added in order to
+ ensure that your Work remains useful to the community even when you can no
+ longer maintain and support it yourself.
+
+
+ \LPPLsubsubsection{Derived Works That Are Not Replacements}
+ \label{LPPL:NotReplacements}
+
+ Several clauses of the \LPPL\ specify means to provide reliability and
+ stability for the user community. They therefore concern themselves with
+ the case that a Derived Work is intended to be used as a (compatible or
+ incompatible) replacement of the original Work. If this is not the case
+ (e.g., if a few lines of code are reused for a completely different task),
+ then clauses 6b and 6d shall not apply.
+
+
+ \LPPLsubsubsection{Important Recommendations}
+ \label{LPPL:Recommendations}
+
+ \LPPLparagraph{Defining What Constitutes the Work}
+
+ The \LPPL\ requires that distributions of the Work contain all the files of
+ the Work. It is therefore important that you provide a way for the
+ licensee to determine which files constitute the Work. This could, for
+ example, be achieved by explicitly listing all the files of the Work near
+ the copyright notice of each file or by using a line such as:
+ %
+\begin{verbatim}
+ % This work consists of all files listed in manifest.txt.
+\end{verbatim}
+ %
+ in that place. In the absence of an unequivocal list it might be
+ impossible for the licensee to determine what is considered by you to
+ comprise the Work and, in such a case, the licensee would be entitled to
+ make reasonable conjectures as to which files comprise the Work.
+\end{LPPLicense}

+\label{label_fdl}
+
+% \textbf{Copyright 2000,2001,2002 Free Software Foundation, Inc.}\par
+% 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA
+% \begin{quotation}
+% Everyone is allowed to distribute verbatim copies of this
+% license document, but modification of it is not allowed.
+% \end{quotation}
+
+\subsubsection{Preamble}
+
+The purpose of this License is to make a manual, textbook, or other functional
+and useful document ``free'' in the sense of freedom: to assure everyone the
+effective freedom to copy and redistribute it, with or without modifying it,
+either commercially or noncommercially. Secondarily, this License preserves for
+the author and publisher a way to get credit for their work, while not being
+considered responsible for modifications made by others.
+
+This License is a kind of ``copyleft'', which means that derivative works of
+the document must themselves be free in the same sense. It complements the GNU
+General Public License, which is a copyleft license designed for free software.
+
+We have designed this License in order to use it for manuals for free software,
+because free software needs free documentation: a free program should come with
+manuals providing the same freedoms that the software does. But this License
+is not limited to software manuals; it can be used for any textual work,
+regardless of subject matter or whether it is published as a printed book. We
+recommend this License principally for works whose purpose is instruction or
+reference.
+
+
+\subsubsection{Applicability and definitions}
+
+This License applies to any manual or other work, in any medium, that contains
+a notice placed by the copyright holder saying it can be distributed under the
+terms of this License. Such a notice grants a world-wide, royalty-free
+license, unlimited in duration, to use that work under the conditions stated
+herein. The \textbf{``Document''}, below, refers to any such manual or work.
+Any member of the public is a licensee, and is addressed as \textbf{``you''}.
+You accept the license if you copy, modify or distribute the work in a way
+requiring permission under copyright law.
+
+A \textbf{``Modified Version''} of the Document means any work containing the
+Document or a portion of it, either copied verbatim, or with modifications
+and/or translated into another language.
+
+A \textbf{``Secondary Section''} is a named appendix or a front-matter section
+of the Document that deals exclusively with the relationship of the publishers
+or authors of the Document to the Document's overall subject (or to related
+matters) and contains nothing that could fall directly within that overall
+subject. (Thus, if the Document is in part a textbook of mathematics, a
+Secondary Section may not explain any mathematics.) The relationship could be
+a matter of historical connection with the subject or with related matters, or
+of legal, commercial, philosophical, ethical or political position regarding
+them.
+
+The \textbf{``Invariant Sections''} are certain Secondary Sections whose titles
+are designated, as being those of Invariant Sections, in the notice that says
+that the Document is released under this License. If a section does not fit
+the above definition of Secondary then it is not allowed to be designated as
+Invariant. The Document may contain zero Invariant Sections. If the Document
+does not identify any Invariant Sections then there are none.
+
+The \textbf{``Cover Texts''} are certain short passages of text that are
+listed, as Front-Cover Texts or Back-Cover Texts, in the notice that says that
+the Document is released under this License. A Front-Cover Text may be at most
+5 words, and a Back-Cover Text may be at most 25 words.
+
+A \textbf{``Transparent''} copy of the Document means a machine-readable copy,
+represented in a format whose specification is available to the general public,
+that is suitable for revising the document straightforwardly with generic text
+editors or (for images composed of pixels) generic paint programs or (for
+drawings) some widely available drawing editor, and that is suitable for input
+to text formatters or for automatic translation to a variety of formats
+suitable for input to text formatters. A copy made in an otherwise Transparent
+file format whose markup, or absence of markup, has been arranged to thwart or
+discourage subsequent modification by readers is not Transparent. An image
+format is not Transparent if used for any substantial amount of text. A copy
+that is not ``Transparent'' is called \textbf{``Opaque''}.
+
+Examples of suitable formats for Transparent copies include plain ASCII without
+markup, Texinfo input format, LaTeX input format, SGML or XML using a publicly
+available DTD, and standard-conforming simple HTML, PostScript or PDF designed
+for human modification. Examples of transparent image formats include PNG, XCF
+and JPG. Opaque formats include proprietary formats that can be read and
+edited only by proprietary word processors, SGML or XML for which the DTD
+and/or processing tools are not generally available, and the machine-generated
+HTML, PostScript or PDF produced by some word processors for output purposes
+only.
+
+The \textbf{``Title Page''} means, for a printed book, the title page itself,
+plus such following pages as are needed to hold, legibly, the material this
+License requires to appear in the title page. For works in formats which do
+not have any title page as such, ``Title Page'' means the text near the most
+prominent appearance of the work's title, preceding the beginning of the body
+of the text.
+
+A section \textbf{``Entitled XYZ''} means a named subunit of the Document whose
+title either is precisely XYZ or contains XYZ in parentheses following text
+that translates XYZ in another language. (Here XYZ stands for a specific
+section name mentioned below, such as \textbf{``Acknowledgements''},
+\textbf{``Dedications''}, \textbf{``Endorsements''}, or \textbf{``History''}.)
+To \textbf{``Preserve the Title''} of such a section when you modify the
+Document means that it remains a section ``Entitled XYZ'' according to this
+definition.
+
+The Document may include Warranty Disclaimers next to the notice which states
+that this License applies to the Document. These Warranty Disclaimers are
+considered to be included by reference in this License, but only as regards
+disclaiming warranties: any other implication that these Warranty Disclaimers
+may have is void and has no effect on the meaning of this License.
+
+
+\subsubsection{Verbatim Copying}
+
+You may copy and distribute the Document in any medium, either commercially or
+noncommercially, provided that this License, the copyright notices, and the
+license notice saying this License applies to the Document are reproduced in
+all copies, and that you add no other conditions whatsoever to those of this
+License. You may not use technical measures to obstruct or control the reading
+or further copying of the copies you make or distribute. However, you may
+accept compensation in exchange for copies. If you distribute a large enough
+number of copies you must also follow the conditions in section~3.
+
+You may also lend copies, under the same conditions stated above, and you may
+publicly display copies.
+
+
+\subsubsection{Copying in Quantity}
+
+If you publish printed copies (or copies in media that commonly have printed
+covers) of the Document, numbering more than 100, and the Document's license
+notice requires Cover Texts, you must enclose the copies in covers that carry,
+clearly and legibly, all these Cover Texts: Front-Cover Texts on the front
+cover, and Back-Cover Texts on the back cover. Both covers must also clearly
+and legibly identify you as the publisher of these copies. The front cover
+must present the full title with all words of the title equally prominent and
+visible. You may add other material on the covers in addition. Copying with
+changes limited to the covers, as long as they preserve the title of the
+Document and satisfy these conditions, can be treated as verbatim copying in
+other respects.
+
+If the required texts for either cover are too voluminous to fit legibly, you
+should put the first ones listed (as many as fit reasonably) on the actual
+cover, and continue the rest onto adjacent pages.
+
+If you publish or distribute Opaque copies of the Document numbering more than
+100, you must either include a machine-readable Transparent copy along with
+each Opaque copy, or state in or with each Opaque copy a computer-network
+location from which the general network-using public has access to download
+using public-standard network protocols a complete Transparent copy of the
+Document, free of added material. If you use the latter option, you must take
+reasonably prudent steps, when you begin distribution of Opaque copies in
+quantity, to ensure that this Transparent copy will remain thus accessible at
+the stated location until at least one year after the last time you distribute
+an Opaque copy (directly or through your agents or retailers) of that edition
+to the public.
+
+It is requested, but not required, that you contact the authors of the Document
+well before redistributing any large number of copies, to give them a chance to
+provide you with an updated version of the Document.
+
+
+\subsubsection{Modifications}
+
+You may copy and distribute a Modified Version of the Document under the
+conditions of sections 2 and 3 above, provided that you release the Modified
+Version under precisely this License, with the Modified Version filling the
+role of the Document, thus licensing distribution and modification of the
+Modified Version to whoever possesses a copy of it. In addition, you must do
+these things in the Modified Version:
+%
+\begin{itemize}
+ \item[A.] Use in the Title Page (and on the covers, if any) a title
+ distinct from that of the Document, and from those of previous
+ versions (which should, if there were any, be listed in the History
+ section of the Document). You may use the same title as a previous
+ version if the original publisher of that version gives permission.
+ \item[B.] List on the Title Page, as authors, one or more persons or
+ entities responsible for authorship of the modifications in the
+ Modified Version, together with at least five of the principal
+ authors of the Document (all of its principal authors, if it has
+ fewer than five), unless they release you from this requirement.
+ \item[C.] State on the Title page the name of the publisher of the
+ Modified Version, as the publisher.
+ \item[D.] Preserve all the copyright notices of the Document.
+ \item[E.] Add an appropriate copyright notice for your modifications
+ adjacent to the other copyright notices.
+ \item[F.] Include, immediately after the copyright notices, a license
+ notice giving the public permission to use the Modified Version under
+ the terms of this License, in the form shown in the Addendum below.
+ \item[G.] Preserve in that license notice the full lists of Invariant
+ Sections and required Cover Texts given in the Document's license
+ notice.
+ \item[H.] Include an unaltered copy of this License.
+ \item[I.] Preserve the section Entitled ``History'', Preserve its Title,
+ and add to it an item stating at least the title, year, new authors,
+ and publisher of the Modified Version as given on the Title Page. If
+ there is no section Entitled ``History'' in the Document, create one
+ stating the title, year, authors, and publisher of the Document as
+ given on its Title Page, then add an item describing the Modified
+ Version as stated in the previous sentence.
+ \item[J.] Preserve the network location, if any, given in the Document
+ for public access to a Transparent copy of the Document, and likewise
+ the network locations given in the Document for previous versions it
+ was based on. These may be placed in the ``History'' section. You
+ may omit a network location for a work that was published at least
+ four years before the Document itself, or if the original publisher
+ of the version it refers to gives permission.
+ \item[K.] For any section Entitled ``Acknowledgements'' or
+ ``Dedications'', Preserve the Title of the section, and preserve in
+ the section all the substance and tone of each of the contributor
+ acknowledgements and/or dedications given therein.
+ \item[L.] Preserve all the Invariant Sections of the Document, unaltered
+ in their text and in their titles. Section numbers or the equivalent
+ are not considered part of the section titles.
+ \item[M.] Delete any section Entitled ``Endorsements''. Such a section
+ may not be included in the Modified Version.
+ \item[N.] Do not retitle any existing section to be Entitled
+ ``Endorsements'' or to conflict in title with any Invariant Section.
+ \item[O.] Preserve any Warranty Disclaimers.
+\end{itemize}
+
+If the Modified Version includes new front-matter sections or appendices that
+qualify as Secondary Sections and contain no material copied from the Document,
+you may at your option designate some or all of these sections as invariant.
+To do this, add their titles to the list of Invariant Sections in the Modified
+Version's license notice. These titles must be distinct from any other section
+titles.
+
+You may add a section Entitled ``Endorsements'', provided it contains nothing
+but endorsements of your Modified Version by various parties--for example,
+statements of peer review or that the text has been approved by an organization
+as the authoritative definition of a standard.
+
+You may add a passage of up to five words as a Front-Cover Text, and a passage
+of up to 25 words as a Back-Cover Text, to the end of the list of Cover Texts
+in the Modified Version. Only one passage of Front-Cover Text and one of
+Back-Cover Text may be added by (or through arrangements made by) any one
+entity. If the Document already includes a cover text for the same cover,
+previously added by you or by arrangement made by the same entity you are
+acting on behalf of, you may not add another; but you may replace the old one,
+on explicit permission from the previous publisher that added the old one.
+
+The author(s) and publisher(s) of the Document do not by this License give
+permission to use their names for publicity for or to assert or imply
+endorsement of any Modified Version.
+
+
+\subsubsection{Combining Documents}
+
+You may combine the Document with other documents released under this License,
+under the terms defined in section 4 above for modified versions, provided that
+you include in the combination all of the Invariant Sections of all of the
+original documents, unmodified, and list them all as Invariant Sections of your
+combined work in its license notice, and that you preserve all their Warranty
+Disclaimers.
+
+The combined work need only contain one copy of this License, and multiple
+identical Invariant Sections may be replaced with a single copy. If there are
+multiple Invariant Sections with the same name but different contents, make the
+title of each such section unique by adding at the end of it, in parentheses,
+the name of the original author or publisher of that section if known, or else
+a unique number. Make the same adjustment to the section titles in the list of
+Invariant Sections in the license notice of the combined work.
+
+In the combination, you must combine any sections Entitled ``History'' in the
+various original documents, forming one section Entitled ``History''; likewise
+combine any sections Entitled ``Acknowledgements'', and any sections Entitled
+``Dedications''. You must delete all sections Entitled ``Endorsements''.
+
+
+\subsubsection{Collection of Documents}
+
+You may make a collection consisting of the Document and other documents
+released under this License, and replace the individual copies of this License
+in the various documents with a single copy that is included in the collection,
+provided that you follow the rules of this License for verbatim copying of each
+of the documents in all other respects.
+
+You may extract a single document from such a collection, and distribute it
+individually under this License, provided you insert a copy of this License
+into the extracted document, and follow this License in all other respects
+regarding verbatim copying of that document.
+
+
+\subsubsection{Aggregating with independent Works}
+
+A compilation of the Document or its derivatives with other separate and
+independent documents or works, in or on a volume of a storage or distribution
+medium, is called an ``aggregate'' if the copyright resulting from the
+compilation is not used to limit the legal rights of the compilation's users
+beyond what the individual works permit. When the Document is included in an
+aggregate, this License does not apply to the other works in the aggregate
+which are not themselves derivative works of the Document.
+
+If the Cover Text requirement of section 3 is applicable to these copies of the
+Document, then if the Document is less than one half of the entire aggregate,
+the Document's Cover Texts may be placed on covers that bracket the Document
+within the aggregate, or the electronic equivalent of covers if the Document is
+in electronic form. Otherwise they must appear on printed covers that bracket
+the whole aggregate.
+
+
+\subsubsection{Translation}
+
+Translation is considered a kind of modification, so you may distribute
+translations of the Document under the terms of section 4. Replacing Invariant
+Sections with translations requires special permission from their copyright
+holders, but you may include translations of some or all Invariant Sections in
+addition to the original versions of these Invariant Sections. You may include
+a translation of this License, and all the license notices in the Document, and
+any Warranty Disclaimers, provided that you also include the original English
+version of this License and the original versions of those notices and
+disclaimers. In case of a disagreement between the translation and the
+original version of this License or a notice or disclaimer, the original
+version will prevail.
+
+If a section in the Document is Entitled ``Acknowledgements'', ``Dedications'',
+or ``History'', the requirement (section 4) to Preserve its Title (section 1)
+will typically require changing the actual title.
+
+
+\subsubsection{Termination}
+
+You may not copy, modify, sublicense, or distribute the Document except as
+expressly provided for under this License. Any other attempt to copy, modify,
+sublicense or distribute the Document is void, and will automatically terminate
+your rights under this License. However, parties who have received copies, or
+rights, from you under this License will not have their licenses terminated so
+long as such parties remain in full compliance.
+
+
+\subsubsection{Future Revisions of this License}
+
+The Free Software Foundation may publish new, revised versions of the GNU Free
+Documentation 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. See http://www.gnu.org/copyleft/.
+
+Each version of the License is given a distinguishing version number. If the
+Document specifies that a particular 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 specified version or of any later version that has
+been published (not as a draft) by the Free Software Foundation. If the
+Document does not specify a version number of this License, you may choose any
+version ever published (not as a draft) by the Free Software Foundation.
+
+
+\subsubsection{Addendum: How to use this License for your documents}
+
+To use this License in a document you have written, include a copy of the
+License in the document and put the following copyright and license notices
+just after the title page:
+
+\bigskip
+\begin{quote}
+ Copyright \copyright \textsc{year your name}.
+ Permission is granted to copy, distribute and/or modify this document
+ under the terms of the GNU Free Documentation License, Version 1.2
+ or any later version published by the Free Software Foundation;
+ with no Invariant Sections, no Front-Cover Texts, and no Back-Cover Texts.
+ A copy of the license is included in the section entitled ``GNU
+ Free Documentation License''.
+\end{quote}
+\bigskip
+
+If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts, replace
+the ``with \dots\ Texts''. line with this:
+
+\bigskip
+\begin{quote}
+ with the Invariant Sections being \textsc{list their titles}, with the
+ Front-Cover Texts being \textsc{list}, and with the Back-Cover
+ Texts being \textsc{list}.
+\end{quote}
+\bigskip
+
+If you have Invariant Sections without Cover Texts, or some other combination
+of the three, merge those two alternatives to suit the situation.
+
+If your document contains nontrivial examples of program code, we recommend
+releasing these examples in parallel under your choice of free software
+license, such as the GNU General Public License, to permit their use in free
+software.
