Creative Commons Attribution 4.0 International Public License

By exercising the Licensed Rights (defined below), You accept and agree
to be bound by the terms and conditions of this Creative Commons
Attribution 4.0 International Public License ("Public License"). To the
extent this Public License may be interpreted as a contract, You are
granted the Licensed Rights in consideration of Your acceptance of
these terms and conditions, and the Licensor grants You such rights in
consideration of benefits the Licensor receives from making the
Licensed Material available under these terms and conditions.

Section 1 -- Definitions.

 a. Adapted Material means material subject to Copyright and Similar
    Rights that is derived from or based upon the Licensed Material
    and in which the Licensed Material is translated, altered,
    arranged, transformed, or otherwise modified in a manner requiring
    permission under the Copyright and Similar Rights held by the
    Licensor. For purposes of this Public License, where the Licensed
    Material is a musical work, performance, or sound recording,
    Adapted Material is always produced where the Licensed Material is
    synched in timed relation with a moving image.

 b. Adapter's License means the license You apply to Your Copyright
    and Similar Rights in Your contributions to Adapted Material in
    accordance with the terms and conditions of this Public License.

 c. Copyright and Similar Rights means copyright and/or similar rights
    closely related to copyright including, without limitation,
    performance, broadcast, sound recording, and Sui Generis Database
    Rights, without regard to how the rights are labeled or
    categorized. For purposes of this Public License, the rights
    specified in Section 2(b)(1)-(2) are not Copyright and Similar
    Rights.

 d. Effective Technological Measures means those measures that, in the
    absence of proper authority, may not be circumvented under laws
    fulfilling obligations under Article 11 of the WIPO Copyright
    Treaty adopted on December 20, 1996, and/or similar international
    agreements.

 e. Exceptions and Limitations means fair use, fair dealing, and/or
    any other exception or limitation to Copyright and Similar Rights
    that applies to Your use of the Licensed Material.

 f. Licensed Material means the artistic or literary work, database,
    or other material to which the Licensor applied this Public
    License.

 g. Licensed Rights means the rights granted to You subject to the
    terms and conditions of this Public License, which are limited to
    all Copyright and Similar Rights that apply to Your use of the
    Licensed Material and that the Licensor has authority to license.

 h. Licensor means the individual(s) or entity(ies) granting rights
    under this Public License.

 i. Share means to provide material to the public by any means or
    process that requires permission under the Licensed Rights, such
    as reproduction, public display, public performance, distribution,
    dissemination, communication, or importation, and to make material
    available to the public including in ways that members of the
    public may access the material from a place and at a time
    individually chosen by them.

 j. Sui Generis Database Rights means rights other than copyright
    resulting from Directive 96/9/EC of the European Parliament and of
    the Council of 11 March 1996 on the legal protection of databases,
    as amended and/or succeeded, as well as other essentially
    equivalent rights anywhere in the world.

 k. You means the individual or entity exercising the Licensed Rights
    under this Public License. Your has a corresponding meaning.

Section 2 -- Scope.

 a. License grant.

      1. Subject to the terms and conditions of this Public License,
         the Licensor hereby grants You a worldwide, royalty-free,
         non-sublicensable, non-exclusive, irrevocable license to
         exercise the Licensed Rights in the Licensed Material to:

           a. reproduce and Share the Licensed Material, in whole or
              in part; and

           b. produce, reproduce, and Share Adapted Material.

      2. Exceptions and Limitations. For the avoidance of doubt, where
         Exceptions and Limitations apply to Your use, this Public
         License does not apply, and You do not need to comply with
         its terms and conditions.

      3. Term. The term of this Public License is specified in Section
         6(a).

      4. Media and formats; technical modifications allowed. The
         Licensor authorizes You to exercise the Licensed Rights in
         all media and formats whether now known or hereafter created,
         and to make technical modifications necessary to do so. The
         Licensor waives and/or agrees not to assert any right or
         authority to forbid You from making technical modifications
         necessary to exercise the Licensed Rights, including
         technical modifications necessary to circumvent Effective
         Technological Measures. For purposes of this Public License,
         simply making modifications authorized by this Section 2(a)
         (4) never produces Adapted Material.

      5. Downstream recipients.

           a. Offer from the Licensor -- Licensed Material. Every
              recipient of the Licensed Material automatically
              receives an offer from the Licensor to exercise the
              Licensed Rights under the terms and conditions of this
              Public License.

           b. No downstream restrictions. You may not offer or impose
              any additional or different terms or conditions on, or
              apply any Effective Technological Measures to, the
              Licensed Material if doing so restricts exercise of the
              Licensed Rights by any recipient of the Licensed
              Material.

      6. No endorsement. Nothing in this Public License constitutes or
         may be construed as permission to assert or imply that You
         are, or that Your use of the Licensed Material is, connected
         with, or sponsored, endorsed, or granted official status by,
         the Licensor or others designated to receive attribution as
         provided in Section 3(a)(1)(A)(i).

 b. Other rights.

      1. Moral rights, such as the right of integrity, are not
         licensed under this Public License, nor are publicity,
         privacy, and/or other similar personality rights; however, to
         the extent possible, the Licensor waives and/or agrees not to
         assert any such rights held by the Licensor to the limited
         extent necessary to allow You to exercise the Licensed
         Rights, but not otherwise.

      2. Patent and trademark rights are not licensed under this
         Public License.

      3. To the extent possible, the Licensor waives any right to
         collect royalties from You for the exercise of the Licensed
         Rights, whether directly or through a collecting society
         under any voluntary or waivable statutory or compulsory
         licensing scheme. In all other cases the Licensor expressly
         reserves any right to collect such royalties.

Section 3 -- License Conditions.

Your exercise of the Licensed Rights is expressly made subject to the
following conditions.

 a. Attribution.

      1. If You Share the Licensed Material (including in modified
         form), You must:

           a. retain the following if it is supplied by the Licensor
              with the Licensed Material:

                i. identification of the creator(s) of the Licensed
                   Material and any others designated to receive
                   attribution, in any reasonable manner requested by
                   the Licensor (including by pseudonym if
                   designated);

               ii. a copyright notice;

              iii. a notice that refers to this Public License;

               iv. a notice that refers to the disclaimer of
                   warranties;

                v. a URI or hyperlink to the Licensed Material to the
                   extent reasonably practicable;

           b. indicate if You modified the Licensed Material and
              retain an indication of any previous modifications; and

           c. indicate the Licensed Material is licensed under this
              Public License, and include the text of, or the URI or
              hyperlink to, this Public License.

      2. You may satisfy the conditions in Section 3(a)(1) in any
         reasonable manner based on the medium, means, and context in
         which You Share the Licensed Material. For example, it may be
         reasonable to satisfy the conditions by providing a URI or
         hyperlink to a resource that includes the required
         information.

      3. If requested by the Licensor, You must remove any of the
         information required by Section 3(a)(1)(A) to the extent
         reasonably practicable.

      4. If You Share Adapted Material You produce, the Adapter's
         License You apply must not prevent recipients of the Adapted
         Material from complying with this Public License.

Section 4 -- Sui Generis Database Rights.

Where the Licensed Rights include Sui Generis Database Rights that
apply to Your use of the Licensed Material:

 a. for the avoidance of doubt, Section 2(a)(1) grants You the right
    to extract, reuse, reproduce, and Share all or a substantial
    portion of the contents of the database;

 b. if You include all or a substantial portion of the database
    contents in a database in which You have Sui Generis Database
    Rights, then the database in which You have Sui Generis Database
    Rights (but not its individual contents) is Adapted Material; and

 c. You must comply with the conditions in Section 3(a) if You Share
    all or a substantial portion of the contents of the database.

For the avoidance of doubt, this Section 4 supplements and does not
replace Your obligations under this Public License where the Licensed
Rights include other Copyright and Similar Rights.

Section 5 -- Disclaimer of Warranties and Limitation of Liability.

 a. UNLESS OTHERWISE SEPARATELY UNDERTAKEN BY THE LICENSOR, TO THE
    EXTENT POSSIBLE, THE LICENSOR OFFERS THE LICENSED MATERIAL AS-IS
    AND AS-AVAILABLE, AND MAKES NO REPRESENTATIONS OR WARRANTIES OF
    ANY KIND CONCERNING THE LICENSED MATERIAL, WHETHER EXPRESS,
    IMPLIED, STATUTORY, OR OTHER. THIS INCLUDES, WITHOUT LIMITATION,
    WARRANTIES OF TITLE, MERCHANTABILITY, FITNESS FOR A PARTICULAR
    PURPOSE, NON-INFRINGEMENT, ABSENCE OF LATENT OR OTHER DEFECTS,
    ACCURACY, OR THE PRESENCE OR ABSENCE OF ERRORS, WHETHER OR NOT
    KNOWN OR DISCOVERABLE. WHERE DISCLAIMERS OF WARRANTIES ARE NOT
    ALLOWED IN FULL OR IN PART, THIS DISCLAIMER MAY NOT APPLY TO YOU.

 b. TO THE EXTENT POSSIBLE, IN NO EVENT WILL THE LICENSOR BE LIABLE
    TO YOU ON ANY LEGAL THEORY (INCLUDING, WITHOUT LIMITATION,
    NEGLIGENCE) OR OTHERWISE FOR ANY DIRECT, SPECIAL, INDIRECT,
    INCIDENTAL, CONSEQUENTIAL, PUNITIVE, EXEMPLARY, OR OTHER LOSSES,
    COSTS, EXPENSES, OR DAMAGES ARISING OUT OF THIS PUBLIC LICENSE OR
    USE OF THE LICENSED MATERIAL, EVEN IF THE LICENSOR HAS BEEN
    ADVISED OF THE POSSIBILITY OF SUCH LOSSES, COSTS, EXPENSES, OR
    DAMAGES. WHERE A LIMITATION OF LIABILITY IS NOT ALLOWED IN FULL OR
    IN PART, THIS LIMITATION MAY NOT APPLY TO YOU.

 c. The disclaimer of warranties and limitation of liability provided
    above shall be interpreted in a manner that, to the extent
    possible, most closely approximates an absolute disclaimer and
    waiver of all liability.

Section 6 -- Term and Termination.

 a. This Public License applies for the term of the Copyright and
    Similar Rights licensed here. However, if You fail to comply with
    this Public License, then Your rights under this Public License
    terminate automatically.

 b. Where Your right to use the Licensed Material has terminated under
    Section 6(a), it reinstates:

      1. automatically as of the date the violation is cured, provided
         it is cured within 30 days of Your discovery of the
         violation; or

      2. upon express reinstatement by the Licensor.

    For the avoidance of doubt, this Section 6(b) does not affect any
    right the Licensor may have to seek remedies for Your violations
    of this Public License.

 c. For the avoidance of doubt, the Licensor may also offer the
    Licensed Material under separate terms or conditions or stop
    distributing the Licensed Material at any time; however, doing so
    will not terminate this Public License.

 d. Sections 1, 5, 6, 7, and 8 survive termination of this Public
    License.

Section 7 -- Other Terms and Conditions.

 a. The Licensor shall not be bound by any additional or different
    terms or conditions communicated by You unless expressly agreed.

 b. Any arrangements, understandings, or agreements regarding the
    Licensed Material not stated herein are separate from and
    independent of the terms and conditions of this Public License.

Section 8 -- Interpretation.

 a. For the avoidance of doubt, this Public License does not, and
    shall not be interpreted to, reduce, limit, restrict, or impose
    conditions on any use of the Licensed Material that could lawfully
    be made without permission under this Public License.

 b. To the extent possible, if any provision of this Public License is
    deemed unenforceable, it shall be automatically reformed to the
    minimum extent necessary to make it enforceable. If the provision
    cannot be reformed, it shall be severed from this Public License
    without affecting the enforceability of the remaining terms and
    conditions.

 c. No term or condition of this Public License will be waived and no
    failure to comply consented to unless expressly agreed to by the
    Licensor.

 d. Nothing in this Public License constitutes or may be interpreted
    as a limitation upon, or waiver of, any privileges and immunities
    that apply to the Licensor or You, including from the legal
    processes of any jurisdiction or authority.

LPPL Version 1.3c  2008-05-04

Copyright 1999 2002-2008 LaTeX3 Project
    Everyone is allowed to distribute verbatim copies of this
    license document, but modification of it is not allowed.


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 `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 `cfgguide.tex'
and `modguide.tex' in the base LaTeX distribution for suggestions.


DEFINITIONS
===========

In this license document the following terms are used:

   `Work'
    Any work being distributed under this License.

   `Derived Work'
    Any work that under any applicable law is derived from the Work.

   `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.

   `Modify'
    To apply any procedure that produces a Derived Work under any
    applicable law.

   `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 FTP or HTTP or by shared file
    systems such as Sun's Network File System (NFS).

   `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.

   `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.

   `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'.



CONDITIONS ON DISTRIBUTION AND MODIFICATION
===========================================

1.  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.

2.  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.

3.  You may distribute a Compiled Work that has been generated from a
complete, unmodified copy of the Work as distributed under Clause 2
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.

4.  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.

5.  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.

6.  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.

  a. 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.

  b. 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.

  c. 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.

  d. You distribute at least one of the following with the Derived Work:

       1. 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;

       2. Information that is sufficient to obtain a complete,
          unmodified copy of the Work.

7.  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 6, above, are met with
regard to the Derived Work.

8.  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 4, above.

9.  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.

10. a. A Derived Work may be distributed under a different license
       provided that license itself honors the conditions listed in
       Clause 6 above, in regard to the Work, though it does not have
       to honor the rest of the conditions in this license.

    b. 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 6 above, concerning changes from the Work.

11. 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.

12.  Nothing in this license is intended to, or may be used to, prevent
complete compliance by all parties with all applicable laws.


NO 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.


MAINTENANCE OF THE WORK
=======================

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:

 1.  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.

 2.  If this search is successful, then enquire whether the Work
     is still maintained.

  a. If it is being maintained, then ask the Current Maintainer
     to update their communication data within one month.

  b. 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 comp.text.tex.)

 3a. If the Current Maintainer is reachable and agrees to pass
     maintenance of the Work to you, then this takes effect
     immediately upon announcement.

  b. 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.

 4.  If you make an `intention announcement' as described in 2b. 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.

 5.  If the previously unreachable Current Maintainer becomes
     reachable once more within three months of a change completed
     under the terms of 3b) or 4), then that Current Maintainer must
     become or remain the Current Maintainer upon request provided
     they then update their communication data within one month.

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 2b) above.


WHETHER AND HOW TO DISTRIBUTE WORKS UNDER THIS LICENSE
======================================================

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.

Choosing This License or Another License
----------------------------------------

If for any part of your work you want or need to use *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 `modguide.tex' in the base LaTeX distribution explains
the motivation behind the conditions of this license.  It explains,
for example, why distributing LaTeX under the GNU General Public
License (GPL) was considered inappropriate.  Even if your work is
unrelated to LaTeX, the discussion in `modguide.tex' may still be
relevant, and authors intending to distribute their works under any
license are encouraged to read it.

A Recommendation on Modification Without Distribution
-----------------------------------------------------

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.

How to Use This License
-----------------------

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:

  %% 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.

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 `pig.dtx', `pig.ins', and `pig.sty' (the last being
generated from `pig.dtx' using `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.

Derived Works That Are Not Replacements
---------------------------------------

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.


Important Recommendations
-------------------------

 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:

    % This work consists of all files listed in manifest.txt.

   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.
