+LaTeX Project Public License
+============================
+
+LPPL Version 1.0 1999-03-01
+
+Copyright 1999 LaTeX3 Project
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but modification is not allowed.
+
+
+Preamble
+========
+
+The LaTeX Project Public License (LPPL) is the license under which the
+base LaTeX distribution is distributed. As described below you may use
+this licence for any software that you wish to distribute.
+
+It may be particularly suitable if your software is TeX related (such
+as a LaTeX package file) but it may be used for any software, even if
+it is unrelated to TeX.
+
+To use this license, the files of your distribution should have an
+explicit copyright notice giving your name and the year, together
+with a reference to this license.
+
+A typical example would be
+
+ %% pig.sty
+ %% Copyright 2001 M. Y. Name
+
+ % This program can redistributed and/or modified under the terms
+ % of the LaTeX Project Public License Distributed from CTAN
+ % archives in directory macros/latex/base/lppl.txt; either
+ % version 1 of the License, or (at your option) any later version.
+
+Given such a notice in the file, the conditions of this document would
+apply, with:
+
+`The Program' referring to the software `pig.sty' and
+`The Copyright Holder' referring to the person `M. Y. Name'.
+
+To see a real example, see the file legal.txt which carries the
+copyright notice for the base latex distribution.
+
+This license gives terms under which files of The Program may be
+distributed and modified. Individual files may have specific further
+constraints on modification, but no file should have restrictions on
+distribution other than those specified below.
+This is to ensure that a distributor wishing to distribute a complete
+unmodified copy of The Program need only check the conditions in this
+file, and does not need to check every file in The Program for extra
+restrictions. If you do need to modify the distribution terms of some
+files, do not refer to this license, instead distribute The Program
+under a different license. You may use the parts of the text of LPPL as
+a model for your own license, but your license should not directly refer
+to the LPPL or otherwise give the impression that The Program is
+distributed under the LPPL.
+
+
+
+The LaTeX Project Public License
+================================
+Terms And Conditions For Copying, Distribution And Modification
+===============================================================
+
+
+WARRANTY
+========
+
+There is no warranty for The Program, to the extent permitted by
+applicable law. Except when otherwise stated in writing, The
+Copyright Holder provides 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.
+
+In no event unless required by applicable law or agreed to in writing
+will The Copyright Holder, or any of the individual authors named in
+the source for The Program, be liable to you for damages, including
+any general, special, incidental or consequential damages arising out
+of any use of The Program or out of inability to use The Program
+(including but not limited to loss of data or data being rendered
+inaccurate or losses sustained by you or by third parties as a result
+of 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.
+
+
+DISTRIBUTION
+============
+
+Redistribution of unchanged files is allowed provided that all files
+that make up the distribution of The Program are distributed.
+In particular this means that The Program has to be distributed
+including its documentation if documentation was part of the original
+distribution.
+
+The distribution of The Program will contain a prominent file
+listing all the files covered by this license.
+
+If you receive only some of these files from someone, complain!
+
+The distribution of changed versions of certain files included in the
+The Program, and the reuse of code from The Program, are allowed
+under the following restrictions:
+
+ * It is allowed only if the legal notice in the file does not
+ expressly forbid it.
+ See note below, under "Conditions on individual files".
+
+ * You rename the file before you make any changes to it, unless the
+ file explicitly says that renaming is not required. Any such changed
+ files must be distributed under a license that forbids distribution
+ of those files, and any files derived from them, under the names used
+ by the original files in the distribution of The Program.
+
+ * You change any `identification string' in The Program to clearly
+ indicate that the file is not part of the standard system.
+
+ * If The Program includes an `error report address' so that errors
+ may be reported to The Copyright Holder, or other specified
+ addresses, this address must be changed in any modified versions of
+ The Program, so that reports for files not maintained by the
+ original program maintainers are directed to the maintainers of the
+ changed files.
+
+ * You acknowledge the source and authorship of the original version
+ in the modified file.
+
+ * You also distribute the unmodified version of the file or
+ alternatively provide sufficient information so that the
+ user of your modified file can be reasonably expected to be
+ able to obtain an original, unmodified copy of The Program.
+ For example, you may specify a URL to a site that you expect
+ will freely provide the user with a copy of The Program (either
+ the version on which your modification is based, or perhaps a
+ later version).
+
+ * If The Program is intended to be used with, or is based on, LaTeX,
+ then files with the following file extensions which have special
+ meaning in LaTeX Software, have special modification rules under the
+ license:
+
+ - Files with extension `.ins' (installation files): these files may
+ not be modified at all because they contain the legal notices
+ that are placed in the generated files.
+
+ - Files with extension `.fd' (LaTeX font definitions files): these
+ files are allowed to be modified without changing the name, but
+ only to enable use of all available fonts and to prevent attempts
+ to access unavailable fonts. However, modified files are not
+ allowed to be distributed in place of original files.
+
+ - Files with extension `.cfg' (configuration files): these files
+ can be created or modified to enable easy configuration of the
+ system. The documentation in cfgguide.tex in the base LaTeX
+ distribution describes when it makes sense to modify or generate
+ such files.
+
+
+The above restrictions are not intended to prohibit, and hence do
+not apply to, the updating, by any method, of a file so that it
+becomes identical to the latest version of that file in The Program.
+
+========================================================================
+
+NOTES
+=====
+
+We believe that these requirements give you the freedom you to make
+modifications that conform with whatever technical specifications you
+wish, whilst maintaining the availability, integrity and reliability of
+The Program. If you do not see how to achieve your goal whilst
+adhering to these requirements then read the document cfgguide.tex
+in the base LaTeX distribution for suggestions.
+
+Because of the portability and exchangeability aspects of systems
+like LaTeX, The LaTeX3 Project deprecates the distribution of
+non-standard versions of components of LaTeX or of generally available
+contributed code for them but such distributions are permitted under the
+above restrictions.
+
+The document modguide.tex in the base LaTeX distribution details
+the reasons for the legal requirements detailed above.
+Even if The Program is unrelated to LaTeX, the argument in
+modguide.tex may still apply, and should be read before
+a modified version of The Program is distributed.
+
+
+Conditions on individual files
+==============================
+
+The individual files may bear additional conditions which supersede
+the general conditions on distribution and modification contained in
+this file. If there are any such files, the distribution of The
+Program will contain a prominent file that lists all the exceptional
+files.
+
+Typical examples of files with more restrictive modification
+conditions would be files that contain the text of copyright notices.
+
+ * The conditions on individual files differ only in the
+ extent of *modification* that is allowed.
+
+ * The conditions on *distribution* are the same for all the files.
+ Thus a (re)distributor of a complete, unchanged copy of The Program
+ need meet only the conditions in this file; it is not necessary to
+ check the header of every file in the distribution to check that a
+ distribution meets these requirements.

+
+LPPL Version 1.1 1999-07-10
+
+Copyright 1999 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 license under which the
+base LaTeX distribution is distributed.
+
+You may use this license for any program that you have written and wish
+to distribute. This license may be particularly suitable if your
+program is TeX-related (such as a LaTeX package), but you may use it
+even if your program is unrelated to TeX. The section `WHETHER AND HOW
+TO DISTRIBUTE PROGRAMS UNDER THIS LICENSE', below, gives instructions,
+examples, and recommendations for authors who are considering
+distributing their programs under this license.
+
+In this license document, `The Program' refers to any program
+distributed under this license.
+
+This license gives conditions under which The Program may be distributed
+and conditions under which modified versions of The Program may be
+distributed. Individual files of The Program may bear supplementary
+and/or superseding conditions on modification of themselves and on the
+distribution of modified versions of themselves, but *no* file of The
+Program may bear supplementary or superseding conditions on the
+distribution of an unmodified copy of the file. A distributor wishing
+to distribute a complete, unmodified copy of The Program therefore
+needs to check the conditions only in this license and nowhere else.
+
+Activities other than distribution and/or modification of The Program
+are not covered by this license; they are outside its scope. In
+particular, the act of running The Program is not restricted.
+
+We, the LaTeX3 Project, believe that the conditions below give you
+the freedom to make and distribute modified versions of The Program
+that conform with whatever technical specifications you wish while
+maintaining the availability, integrity, and reliability of
+The Program. If you do not see how to achieve your goal while
+meeting these conditions, then read the document `cfgguide.tex'
+in the base LaTeX distribution for suggestions.
+
+
+CONDITIONS ON DISTRIBUTION AND MODIFICATION
+===========================================
+
+You may distribute a complete, unmodified copy of The Program.
+Distribution of only part of The Program is not allowed.
+
+You may not modify in any way a file of The Program that bears a legal
+notice forbidding modification of that file.
+
+You may distribute a modified file of The Program if, and only if, the
+following eight conditions are met:
+
+ 1. You must meet any additional conditions borne by the file on the
+ distribution of a modified version of the file as described below
+ in the subsection `Additional Conditions on Individual Files of
+ The Program'.
+
+ 2. If the file is a LaTeX software file, then you must meet any
+ applicable additional conditions on the distribution of a modified
+ version of the file that are described below in the subsection
+ `Additional Conditions on LaTeX Software Files'.
+
+ 3. You must not distribute the modified file with the filename of the
+ original file.
+
+ 4. In the modified file, you must acknowledge the authorship and
+ name of the original file, and the name (if any) of the program
+ which contains it.
+
+ 5. You must change any identification string in the file to indicate
+ clearly that the modified file is not part of The Program.
+
+ 6. You must change any addresses in the modified file for the
+ reporting of errors in the file or in The Program generally to
+ ensure that reports for files no longer maintained by the original
+ maintainers will be directed to the maintainers of the modified
+ files.
+
+ 7. You must distribute the modified file under a license that forbids
+ distribution both of the modified file and of any files derived
+ from the modified file with the filename of the original file.
+
+ 8. You must do either (A) or (B):
+
+ (A) distribute a copy of The Program (that is, a complete,
+ unmodified copy of The Program) together with the modified
+ file; if your distribution of the modified file is made by
+ offering access to copy the modified file from a designated
+ place, then offering equivalent access to copy The Program
+ from the same place meets this condition, even though third
+ parties are not compelled to copy The Program along with the
+ modified file;
+
+ (B) provide to those who receive the modified file information
+ that is sufficient for them to obtain a copy of The Program;
+ for example, you may provide a Uniform Resource Locator (URL)
+ for a site that you expect will provide them with a copy of
+ The Program free of charge (either the version from which
+ your modification is derived, or perhaps a later version).
+
+Note that in the above, `distribution' of a file means making the
+file available to others by any means. This includes, for instance,
+installing the file on any machine in such a way that the file is
+accessible by users other than yourself. `Modification' of a file
+means any procedure that produces a derivative file under any
+applicable law -- that is, a file containing the original file or
+a significant portion of it, either verbatim or with modifications
+and/or translated into another language.
+
+Changing the name of a file is considered to be a modification of
+the file.
+
+The distribution conditions in this license do not have to be
+applied to files that have been modified in accordance with the
+above conditions. Note, however, that Condition 7. does apply to
+any such modified file.
+
+The conditions above are not intended to prohibit, and hence do not
+apply to, the updating, by any method, of a file so that it becomes
+identical to the latest version of that file of The Program.
+
+
+
+A Recommendation on Modification Without Distribution
+-----------------------------------------------------
+
+It is wise never to modify a file of The Program, even for your own
+personal use, without also meeting the above eight conditions for
+distributing the modified file. While you might intend that such
+modified files will never be distributed, often this will happen by
+accident -- you may forget that you have modified the file; or it may
+not occur to you when allowing others to access the modified file
+that you are thus distributing it and violating the conditions of
+this license. It is usually in your best interest to keep your copy
+of The Program identical with the public one. Many programs provide
+ways to control the behavior of that program without altering its
+licensed files.
+
+
+Additional Conditions on Individual Files of The Program
+--------------------------------------------------------
+
+An individual file of The Program may bear additional conditions that
+supplement and/or supersede the conditions in this license if, and only
+if, such additional conditions exclusively concern modification of the
+file or distribution of a modified version of the file. The conditions
+on individual files of The Program therefore may differ only with
+respect to the kind and extent of modification of those files that
+is allowed, and with respect to the distribution of modified versions
+of those files.
+
+
+Additional Conditions on LaTeX Software Files
+---------------------------------------------
+
+If a file of The Program is intended to be used with LaTeX (that is,
+if it is a LaTeX software file), then the following additional
+conditions, which supplement and/or supersede the conditions
+above, apply to the file according to its filename extension:
+
+ - You may not modify any file with filename extension `.ins' since
+ these are installation files containing the legal notices that are
+ placed in the files they generate.
+
+ - You may distribute modified versions of files with filename
+ extension `.fd' (LaTeX font definition files) under the standard
+ conditions of the LPPL as described above. You may also distribute
+ such modified LaTeX font definition files with their original names
+ provided that:
+ (1) the only changes to the original files either enable use of
+ available fonts or prevent attempts to access unavailable fonts;
+ (2) you also distribute the original, unmodified files (TeX input
+ paths can be used to control which set of LaTeX font definition
+ files is actually used by TeX).
+
+ - You may distribute modified versions of files with filename
+ extension `.cfg' (configuration files) with their original names.
+ The Program may (and usually will) specify the range of commands
+ that are allowed in a particular configuration file.
+
+Because of portability and exchangeability issues in LaTeX software,
+The LaTeX3 Project deprecates the distribution of modified versions of
+components of LaTeX or of generally available contributed code for them,
+but such distribution can meet the conditions of this license.
+
+
+NO WARRANTY
+===========
+
+There is no warranty for The Program. Except when otherwise stated in
+writing, The Copyright Holder provides 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.
+
+In no event unless agreed to in writing will The Copyright Holder, or
+any author named in the files of The Program, or any other party who may
+distribute and/or modify The Program as permitted below, be liable to
+you for damages, including any general, special, incidental or
+consequential damages arising out of any use of The Program or out of
+inability to use The Program (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 Program 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.
+
+
+WHETHER AND HOW TO DISTRIBUTE PROGRAMS UNDER THIS LICENSE
+=========================================================
+
+This section contains important instructions, examples, and
+recommendations for authors who are considering distributing their
+programs under this license. These authors are addressed as `you' in
+this section.
+
+
+Choosing This License or Another License
+----------------------------------------
+
+If for any part of your program you want or need to use *distribution*
+conditions that differ from those in this license, then do not refer to
+this license anywhere in your program but instead distribute your
+program 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 program 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 program is
+unrelated to LaTeX, the discussion in `modguide.tex' may still be
+relevant, and authors intending to distribute their programs under any
+license are encouraged to read it.
+
+
+How to Use This License
+-----------------------
+
+To use this license, place in each of the files of your program both
+an explicit copyright notice including your name and the year and also
+a statement that the distribution and/or modification of the file is
+constrained by the conditions in this license.
+
+Here is an example of such a notice and statement:
+
+ %% pig.dtx
+ %% Copyright 2001 M. Y. Name
+ %
+ % This program may be distributed and/or modified under the
+ % conditions of the LaTeX Project Public License, either version 1.1
+ % 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 1.1 or later is part of all distributions of LaTeX
+ % version 1999/06/01 or later.
+ %
+ % This program consists of the files pig.dtx and pig.ins
+
+Given such a notice and statement in a file, the conditions given in
+this license document would apply, with `The Program' referring to the
+two files `pig.dtx' and `pig.ins', and `The Copyright Holder' referring
+to the person `M. Y. Name'.
+
+
+Important Recommendations
+-------------------------
+
+ Defining What Constitutes The Program
+
+ The LPPL requires that distributions of The Program contain all the
+ files of The Program. It is therefore important that you provide a
+ way for the licensee to determine which files constitute The Program.
+ This could, for example, be achieved by explicitly listing all the
+ files of The Program near the copyright notice of each file or by
+ using a line like
+
+ % This program 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 Program.
+
+ Noting Exceptional Files
+
+ If The Program contains any files bearing additional conditions on
+ modification, or on distribution of modified versions, of those
+ files (other than those listed in `Additional Conditions on LaTeX
+ Software Files'), then it is recommended that The Program contain a
+ prominent file that defines the exceptional conditions, and either
+ lists the exceptional files or defines one or more categories of
+ exceptional files.
+
+ Files containing the text of a license (such as this file) are
+ often examples of files bearing more restrictive conditions on
+ modification. LaTeX configuration files (with filename extension
+ `.cfg') are examples of files bearing less restrictive conditions
+ on the distribution of a modified version of the file. The
+ additional conditions on LaTeX software given above are examples
+ of declaring a category of files bearing exceptional additional
+ conditions.

+It is wise never to modify a file of The Program, even for your own
+personal use, without also meeting the above eight conditions for
+distributing the modified file. While you might intend that such
+modified files will never be distributed, often this will happen by
+accident -- you may forget that you have modified the file; or it may
+not occur to you when allowing others to access the modified file
+that you are thus distributing it and violating the conditions of
+this license. It is usually in your best interest to keep your copy
+of The Program identical with the public one. Many programs provide
+ways to control the behavior of that program without altering its
+licensed files.
+
+
+Additional Conditions on Individual Files of The Program
+--------------------------------------------------------
+
+An individual file of The Program may bear additional conditions that
+supplement and/or supersede the conditions in this license if, and only
+if, such additional conditions exclusively concern modification of the
+file or distribution of a modified version of the file. The conditions
+on individual files of The Program therefore may differ only with
+respect to the kind and extent of modification of those files that
+is allowed, and with respect to the distribution of modified versions
+of those files.
+
+
+Additional Conditions on LaTeX Software Files
+---------------------------------------------
+
+If a file of The Program is intended to be used with LaTeX (that is,
+if it is a LaTeX software file), then the following additional
+conditions, which supplement and/or supersede the conditions
+above, apply to the file according to its filename extension:
+
+ - You may not modify any file with filename extension `.ins' since
+ these are installation files containing the legal notices that are
+ placed in the files they generate.
+
+ - You may distribute modified versions of files with filename
+ extension `.fd' (LaTeX font definition files) under the standard
+ conditions of the LPPL as described above. You may also distribute
+ such modified LaTeX font definition files with their original names
+ provided that:
+ (1) the only changes to the original files either enable use of
+ available fonts or prevent attempts to access unavailable fonts;
+ (2) you also distribute the original, unmodified files (TeX input
+ paths can be used to control which set of LaTeX font definition
+ files is actually used by TeX).
+
+ - You may distribute modified versions of files with filename
+ extension `.cfg' (configuration files) with their original names.
+ The Program may (and usually will) specify the range of commands
+ that are allowed in a particular configuration file.
+
+Because of portability and exchangeability issues in LaTeX software,
+The LaTeX3 Project deprecates the distribution of modified versions of
+components of LaTeX or of generally available contributed code for them,
+but such distribution can meet the conditions of this license.
+
+
+NO WARRANTY
+===========
+
+There is no warranty for The Program. Except when otherwise stated in
+writing, The Copyright Holder provides 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.
+
+In no event unless agreed to in writing will The Copyright Holder, or
+any author named in the files of The Program, or any other party who may
+distribute and/or modify The Program as permitted above, be liable to
+you for damages, including any general, special, incidental or
+consequential damages arising out of any use of The Program or out of
+inability to use The Program (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 Program 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.
+
+
+WHETHER AND HOW TO DISTRIBUTE PROGRAMS UNDER THIS LICENSE
+=========================================================
+
+This section contains important instructions, examples, and
+recommendations for authors who are considering distributing their
+programs under this license. These authors are addressed as `you' in
+this section.
+
+
+Choosing This License or Another License
+----------------------------------------
+
+If for any part of your program you want or need to use *distribution*
+conditions that differ from those in this license, then do not refer to
+this license anywhere in your program but instead distribute your
+program 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 program 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 program is
+unrelated to LaTeX, the discussion in `modguide.tex' may still be
+relevant, and authors intending to distribute their programs under any
+license are encouraged to read it.
+
+
+How to Use This License
+-----------------------
+
+To use this license, place in each of the files of your program both
+an explicit copyright notice including your name and the year and also
+a statement that the distribution and/or modification of the file is
+constrained by the conditions in this license.
+
+Here is an example of such a notice and statement:
+
+ %% pig.dtx
+ %% Copyright 2001 M. Y. Name
+ %
+ % This program may be distributed and/or modified under the
+ % conditions of the LaTeX Project Public License, either version 1.2
+ % 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 1.2 or later is part of all distributions of LaTeX
+ % version 1999/12/01 or later.
+ %
+ % This program consists of the files pig.dtx and pig.ins
+
+Given such a notice and statement in a file, the conditions given in
+this license document would apply, with `The Program' referring to the
+two files `pig.dtx' and `pig.ins', and `The Copyright Holder' referring
+to the person `M. Y. Name'.
+
+
+Important Recommendations
+-------------------------
+
+ Defining What Constitutes The Program
+
+ The LPPL requires that distributions of The Program contain all the
+ files of The Program. It is therefore important that you provide a
+ way for the licensee to determine which files constitute The Program.
+ This could, for example, be achieved by explicitly listing all the
+ files of The Program near the copyright notice of each file or by
+ using a line like
+
+ % This program 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 Program.
+
+ Noting Exceptional Files
+
+ If The Program contains any files bearing additional conditions on
+ modification, or on distribution of modified versions, of those
+ files (other than those listed in `Additional Conditions on LaTeX
+ Software Files'), then it is recommended that The Program contain a
+ prominent file that defines the exceptional conditions, and either
+ lists the exceptional files or defines one or more categories of
+ exceptional files.
+
+ Files containing the text of a license (such as this file) are
+ often examples of files bearing more restrictive conditions on
+ modification. LaTeX configuration files (with filename extension
+ `.cfg') are examples of files bearing less restrictive conditions
+ on the distribution of a modified version of the file. The
+ additional conditions on LaTeX software given above are examples
+ of declaring a category of files bearing exceptional additional
+ conditions.

+LPPL Version 1.3 2003-12-01
+
+Copyright 1999 2002-03 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 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
+you may use it with small modifications 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".
+
+
+
+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 this 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 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 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 2003 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 2003/12/01 or later.
+ %
+ % This work has the LPPL maintenance status "maintained".
+ %
+ % This 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'.
+
+To prevent the Maintenance section of LPPL from allowing someone else
+to become the Current Maintainer without your agreement, you could
+change "maintained" above into "author-maintained".
+
+
+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.

+PREAMBLE
+========
+
+The LaTeX Project Public License (LPPL) is the primary license under
+which the 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
+you may use it with small modifications 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

+
+
+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".
+
+
+
+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 this 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 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 2003 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 2003/12/01 or later.
+ %
+ % This work has the LPPL maintenance status "maintained".
+ %
+ % This 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.
+
+
+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.

+Copyright 1999 2002-2006 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 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
+you may use it with small modifications 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.

+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.
+
