+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.

+# `apxproof`: Proofs in Appendix
+
+## About
+
+The `apxproof` package facilitates the writing of scientific article
+with proofs deferred to the appendix. The documentation of this package
+is provided in the [apxproof.pdf](apxproof.pdf) file.
+
+## Prerequisites
+
+In addition to a working installation of LaTeX2e, `apxproof` relies on a
+few other packages, which should be provided by all reasonable LaTeX
+distributions:
+ - `amsthm`
+ - `bibunits`
+ - `environ`
+ - `etoolbox`
+ - `fancyvrb`
+ - `ifthen`
+ - `kvoptions`
+
+## Manual installation
+
+Simply copy the file [apxproof.sty](apxproof.sty) in your LaTeX working directory, or
+in any other directory where LaTeX searches for packages.

+\begin{proofsketch}
+  Proof sketch of Theorem~\ref{th:titi}.
+\end{proofsketch}
+
+\begin{proof}
+  Proof of Theorem~\ref{th:titi}.
+
+  For some reason, this proof has an inline Lemma:
+  \begin{lemma}
+    This is the lemma.
+  \end{lemma} 
+
+  \begin{nestedproof}
+    And this lemma has a proof as well!
+  \end{nestedproof}
+
+  This concludes the global proof of Theorem~\ref{th:titi}.
+\end{proof}
+
+\begin{theoremrep}
+  \label{th:tutu}
+  Another great result, without any proof sketch.
+\end{theoremrep}
+
+\begin{proof}
+  Proof of Theorem~\ref{th:tutu}. It has two
+  references~\cite{sitemaps,brin1998anatomy}.
+\end{proof}
+
+\begin{theorem}
+  A regular theorem, not repeated.
+\end{theorem}
+
+\begin{proof}
+This regular theorem is naturally followed with an inline proof.
+\end{proof}
+
+\begin{theoremrep}
+  \label{th:weird}
+  A repeated theorem, but with two proofs, one in Appendix and one in
+  main text.
+\end{theoremrep}
+
+\begin{inlineproof}
+  Main text proof of Theorem~\ref{th:weird}.
+\end{inlineproof}
+
+\begin{proof}
+  Appendix proof of Theorem~\ref{th:weird}.
+\end{proof}
+
+\begin{toappendix}
+And now for no particular reason, two isolated proofs in the appendix,
+  written in two different ways:
+
+  \begin{proof}[Proof of a non-existing result]
+    First with a regular \texttt{proof} environment inside a
+    \texttt{toappendix} environment.
+  \end{proof}
+\end{toappendix}
+
+\begin{appendixproof}
+  Second, with the specific \texttt{appendixproof} environment (but then,
+  cannot change the proof name).
+\end{appendixproof}
+
+\section{Last Section}
+
+\begin{theoremrep}
+  Another theorem.
+\end{theoremrep}
+
+\begin{toappendix}
+  This theorem does not have a proof, but a discussion in the appendix.
+  \textsf{apxproof} can figure, because of the \verb|theorem| environment
+  that follows, that the proof of the following theorem is not a proof of
+  this theorem.
+\end{toappendix}
+
+\begin{theorem}
+  Last theorem, not repeated.
+\end{theorem}
+
+\begin{proof}
+  Proof, inlined.
+\end{proof}

+% SIG-ALTERNATE.CLS - VERSION 2.5
+% "COMPATIBLE" WITH THE "ACM_PROC_ARTICLE-SP.CLS" V3.2SP
+% Gerald Murray - May 23rd 2012
+%
+% ---- Start of 'updates'  ----
+% Changed $10 fee to $15 -- May 2012  --  Gerry
+% Changed $5 fee to $10 --  April 2009 -- Gerry
+% April 22nd. 2009 - Fixed 'Natbib' incompatibility problem - Gerry
+% April 22nd. 2009 - Fixed 'Babel' incompatibility problem - Gerry
+% April 22nd. 2009 - Inserted various bug-fixes and improvements - Gerry
+%
+% To produce Type 1 fonts in the document plus allow for 'normal LaTeX accenting' in the critical areas;
+% title, author block, section-heads, confname, etc. etc. 
+% i.e. the whole purpose of this version update is to NOT resort to 'inelegant accent patches'.
+% After much research, three extra .sty packages were added to the the tail (ae, aecompl, aeguill) to solve,
+% in particular, the accenting problem(s). We _could_ ask authors (via instructions/sample file) to 'include' these in
+% the source .tex file - in the preamble - but if everything is already provided ('behind the scenes' - embedded IN the .cls)
+% then this is less work for authors and also makes everything appear 'vanilla'.
+% NOTE: all 'patchwork accenting" has been commented out (here) and is no longer 'used' in the sample .tex file (either).
+% Gerry June 2007
+%
+% Patch for accenting in conference name/location. Gerry May 3rd. 2007
+% Rule widths changed to .5, author count (>6) fixed, roll-back for Type 3 problem. Gerry March 20th. 2007
+% Changes made to 'modernize' the fontnames but esp. for MikTeX users V2.4/2.5 - Nov. 30th. 2006
+% Updated the \email definition to allow for its use inside of 'shared affiliations' - Nov. 30th. 2006
+% Fixed the 'section number depth value' - Nov. 30th. 2006
+%
+% Footnotes inside table cells using \minipage (Oct. 2002)
+% Georgia fixed bug in sub-sub-section numbering in paragraphs (July 29th. 2002)
+% JS/GM fix to vertical spacing before Proofs (July 30th. 2002)
+%
+% Made the Permission Statement / Conference Info / Copyright Info
+% 'user definable' in the source .tex file OR automatic if
+% not specified.
+%
+% Allowance made to switch default fonts between those systems using
+% normal/modern font names and those using 'Type 1' or 'Truetype' fonts.
+% See LINE NUMBER 255 for details.
+% Also provided for enumerated/annotated Corollaries 'surrounded' by
+% enumerated Theorems (line 848).

+% SIG-ALTERNATE DOCUMENT STYLE
+% G.K.M. Tobin August-October 1999
+%    adapted from ARTICLE document style by Ken Traub, Olin Shivers
+%    also using elements of esub2acm.cls
+% HEAVILY MODIFIED, SUBSEQUENTLY, BY GERRY MURRAY 2000
+% ARTICLE DOCUMENT STYLE -- Released 16 March 1988
+%    for LaTeX version 2.09
+% Copyright (C) 1988 by Leslie Lamport
+%
+%
+%%% sig-alternate.cls is an 'ALTERNATE' document style for producing
+%%% two-column camera-ready pages for ACM conferences.
+%%% THIS FILE DOES NOT STRICTLY ADHERE TO THE SIGS (BOARD-ENDORSED)
+%%% PROCEEDINGS STYLE. It has been designed to produce a 'tighter'
+%%% paper in response to concerns over page budgets.
+%%% The main features of this style are:
+%%%
+%%% 1)  Two columns.
+%%% 2)  Side and top margins of 4.5pc, bottom margin of 6pc, column gutter of
+%%%     2pc, hence columns are 20pc wide and 55.5pc tall.  (6pc =3D 1in, approx)
+%%% 3)  First page has title information, and an extra 6pc of space at the
+%%%     bottom of the first column for the ACM copyright notice.
+%%% 4)  Text is 9pt on 10pt baselines; titles (except main) are 9pt bold.
+%%%
+%%%
+%%% There are a few restrictions you must observe:
+%%%
+%%% 1)  You cannot change the font size; ACM wants you to use 9pt.
+%%% 3)  You must start your paper with the \maketitle command.  Prior to the
+%%%     \maketitle you must have \title and \author commands.  If you have a
+%%%     \date command it will be ignored; no date appears on the paper, since
+%%%     the proceedings will have a date on the front cover.
+%%% 4)  Marginal paragraphs, tables of contents, lists of figures and tables,
+%%%     and page headings are all forbidden.
+%%% 5)  The `figure' environment will produce a figure one column wide; if you
+%%%     want one that is two columns wide, use `figure*'.
+%%%
+%
+%%% Copyright Space:
+%%% This style automatically reserves 1" blank space at the bottom of page 1/
+%%% column 1.  This space can optionally be filled with some text using the
+%%% \toappear{...} command.  If used, this command must be BEFORE the \maketitle
+%%% command.  If this command is defined AND [preprint] is on, then the

+% The following section (i.e. 3 .sty inclusions) was added in May 2007 so as to fix the problems that many
+% authors were having with accents. Sometimes accents would occur, but the letter-character would be of a different
+% font. Conversely the letter-character font would be correct but, e.g. a 'bar' would appear superimposed on the
+% character instead of, say, an unlaut/diaresis. Sometimes the letter-character would NOT appear at all.
+% Using [T1]{fontenc} outright was not an option as this caused 99% of the authors to 'produce' a Type-3 (bitmapped)
+% PDF file - useless for production. 
+%
+% For proper (font) accenting we NEED these packages to be part of the .cls file i.e. 'ae', 'aecompl' and 'aeguil'

+%% This is file `aeguill.sty' 
+% This file gives french guillemets (and not guillemots!)
+% built with the Polish CMR fonts (default), WNCYR fonts, the LASY fonts 
+% or with the EC fonts. 
+% This is useful in conjunction with the ae package
+% (this package loads the ae package in case it has not been loaded)
+%  and with or without the french(le) package.
+%
+% In order to get the guillemets, it is necessary to either type
+% \guillemotleft and \guillemotright, or to use an 8 bit encoding
+% (such as ISO-Latin1) which selects these two commands, 
+% or, if you use the french package (but not the frenchle package), 
+% to type << or >>.
+%
+% By default, you get the Polish CMR guillemets; if this package is loaded
+% with the `cm' option, you get the LASY guillemets; with `ec,' you
+% get the EC guillemets, and with `cyr,' you get the cyrillic guillemets.
+%
+% In verbatim mode, you always get the EC/TT guillemets.
+%
+% The default option is interesting in conjunction with PDF,
+% because there is a Type 1 version of the Polish CMR fonts
+% and these guillemets are very close in shape to the EC guillemets.
+% There are no free Type 1 versions of the EC fonts.
+%
+% Support for Polish CMR guillemets was kindly provided by 
+% Rolf Niepraschk <niepraschk@ptb.de> in version 0.99 (2000/05/22).
+% Bernd Raichle provided extensive simplifications to the code
+% for version 1.00.
+%
+% This package is released under the LPPL.

+%   Date        version

+% 
+% \begin{abstract}
+% This package makes it easier to write articles where proofs and other material
+% are deferred to the appendix. The appendix material is written in the \LaTeX{}
+% code along with the main text which it naturally complements, and it is
+% automatically deferred. The package can automatically send proofs in the
+% appendix, can repeat in the appendix the theorem environments stated in the
+% main text, can section the appendix automatically based on the sectioning of
+% the main text, and supports a separate bibliography for the appendix material.
+% \end{abstract}
+%
+% \section{Usage}
+% The \textsf{apxproof} package is intended to simplify the writing of articles where some of
+% the content needs to be deferred to an appendix. This is in particular
+% useful for the submission of scientific articles to conferences or
+% journals that limit the number of pages in the main text but allow an
+% extra appendix, where proofs of theorems and other material can be added.
+%
+% \subsection{Basics}
+% To use \textsf{apxproof}, first load it in the header of your document:
+% \begin{quote}|\usepackage{apxproof}|\end{quote}
+% On its own, this does not do anything and should not change the
+% appearance of your document. To add an appendix with some material from
+% your document, use the |toappendix| environment:
+% \begin{quote}
+% |\begin{toappendix}|\DescribeEnv{toappendix}\\
+% \hspace*{1em}\dots\\
+% |\end{toappendix}|
+% \end{quote}
+% The content will appear at the end of your document, in an
+% automatically generated section that refers to the current section in the main
+% text.
+% \begin{example}
+% Throughout this documentation, all examples produce content
+% deferred to the appendix, at the very end of this document.
+% \begin{verbatim}
+% \begin{toappendix}
+% This content is in the appendix.
+% \end{toappendix}
+% \end{verbatim}
+% \begin{toappendix}
+%<*driver>
+This content is in the appendix.
+%</driver>
+% \end{toappendix}
+% \end{example}
+% \subsection{Repeated Theorems and Proofs}
+% In some scientific papers that include proofs, it is common to defer
+% proofs to the appendix. This can easily be achieved using the
+% |appendixproof| environment:
+% \begin{quote}
+% |\begin{appendixproof}|\DescribeEnv{appendixproof}\\
+% \hspace*{1em}\dots\\
+% |\end{appendixproof}|
+% \end{quote}
+% This behaves like the |toappendix| environment, except that 
+% a proof environment is generated.
+% \begin{example}We now send a proof to the appendix:
+% \begin{verbatim}
+% \begin{appendixproof}
+% This proof is in the appendix.
+% \end{appendixproof}
+% \end{verbatim}
+% \begin{appendixproof}
+%<*driver>
+This proof is in the appendix.
+%</driver>
+% \end{appendixproof}
+% \end{example}
+%
+% When deferring proofs to the appendix, an annoying problem is that the
+% statement of the theorem remains in the main text; it is hard to read a
+% proof that is far away from the statement it proves. \textsf{apxproof}
+% solves this issue by allowing statements of theorems to be \emph{repeated}:
+% once in the main text, and once in the appendix before the proof of
+% the statement. To use this feature, you can define a new
+% \emph{repeated theorem} environment using the |\newtheoremrep| command:
+% \begin{quote}
+% |\newtheoremrep|\marg{name}\oarg{counter}\marg{title}\DescribeMacro{\newtheoremrep}
+% \end{quote}
+% Usage is exactly the same as that of AMS \LaTeX{}'s |\newtheorem|
+% macro: \meta{name} (e.g., |theorem|) is the name of an environment that is created for this kind of
+% theorem, \meta{counter} (e.g., |definition|) is an optional counter describing
+% from which kind of enviroment should the numbering of these environments be
+% inherited, and \meta{title}
+% (e.g., |Theorem| is
+% the title that will be used to display this theorem environment. What
+% differs from |\newtheorem| is that, when the following is written:
+% \begin{quote}
+% |\newtheoremrep{foobar}{Foobar}|
+% \end{quote}
+% then \emph{two} environments are defined: the \verb|foobar|
+% environment, which behaves as if |\newtheorem| had been used, and the
+% |foobarrep| environment, which results in the statement of this
+% environment being repeated in the appendix.
+%
+% One interesting feature of \textsf{apxproof} is that in most
+% situations, there is no need to use the |appendixproof| environment.
+% Indeed, the |proof| \DescribeEnv{proof} environment is redefined by \textsf{apxproof} to
+% automatically put the proof either in the main text (if it follows a
+% regular theorem) or in the appendix (if it follows a repeated
+% theorem).
+% \begin{example}
+% Assume we have first defined a repeated theorem environment |foobar| as
+% above.
+% We can now use this theorem environment, first for a regular theorem in
+% the main text, then for a theorem repeated in the main text and in the
+% appendix:
+% \begin{quote}
+% \begin{verbatim}
+% \begin{foobar}
+% This foobar is a regular one, in the main text.
+% \end{foobar}
+% \begin{proof}
+% This is the proof of the regular foobar.
+% \end{proof}
+% \end{verbatim}
+% \end{quote}
+% We obtain:
+% \begin{foobar}
+% This foobar is a regular one, in the main text.
+% \end{foobar}
+% \begin{proof}
+% This is the proof of the regular foobar.
+% \end{proof}
+% \begin{quote}
+% \begin{verbatim}
+% \begin{foobarrep}
+% This foobar is repeated in the appendix.
+% \end{foobarrep}
+% \begin{proof}
+% This is the proof of the repeated foobar.
+% \end{proof}
+% \end{verbatim}
+% \end{quote}
+% We now obtain:
+% \begin{foobarrep}
+% This foobar is repeated in the appendix.
+% \end{foobarrep}
+% \begin{proof}
+%<*driver>
+This is the proof of the repeated foobar.
+%</driver>
+% \end{proof}
+% Note that, since |hyperref| is loaded, there is a hyperlink
+% created from the statement of the theorem in the appendix to that in
+% the main text.
+% \end{example}
+%
+% When the proof is deferred to the appendix, it is common practice to
+% add a proof sketch in the main text. \textsf{apxproof} defines a simple
+% |proofsketch| environment for this purpose:
+% \begin{quote}
+% |\begin{proofsketch}|\DescribeEnv{proofsketch}\\
+% \hspace*{1em}\dots\\
+% |\end{proofsketch}|
+% \end{quote}
+% The proof sketch is typeset similarly to a proof, but is always in the
+% main text. Similarly, an |inlineproof| \DescribeEnv{inlineproof}
+% environment is provided so as to
+% be able to have both a proof in the appendix (using the regualr |proof|
+% environment, or alternatively the |appendixproof| environment) and a
+% different proof in the main text (using the |inlineproof| environment).
+% \begin{example} Here are simple examples of proof sketches and inline
+% proofs:
+% \begin{verbatim}
+% \begin{proofsketch}
+% This is a proof sketch.
+% \end{proofsketch}
+% \end{verbatim}
+% \begin{proofsketch}
+% This is a proof sketch.
+% \end{proofsketch}
+% \begin{verbatim}
+% \begin{inlineproof}
+% This is an inline proof.
+% \end{inlineproof}
+% \end{verbatim}
+% \begin{inlineproof}
+% This is an inline proof.
+% \end{inlineproof}
+% \end{example}
+% 
+% \subsection{Bibliography}
+% \textsf{apxproof} automatically adds a bibliography in the appendix
+% with only the references cited in the appendix material. This allows for a
+% clean separation of references used solely in the main text, and those
+% used in the appendix.
+% \begin{example}
+% Assume we have citations both in the main text and in the appendix.
+% \begin{verbatim}
+% This is a citation in the main text~\cite{lamport86}.
+% \begin{toappendix}
+% This is a citation in the appendix~\cite{proofsAreHard}.
+% \end{toappendix}
+% \end{verbatim}
+% This is a citation in the main text~\cite{lamport86}.
+% \begin{toappendix}
+%<*driver>
+This is a citation in the appendix~\cite{proofsAreHard}.
+%</driver>
+% \end{toappendix}
+% \end{example}
+% The bibliography in the appendix can use
+% a different style and heading than the bibliography in the main text (and, by
+% default, it does). See
+% Section~\ref{sec:customization} for how to configure the appearance of
+% that bibliography.
+% \subsection{Mode}
+% An optional \meta{mode} can be specified when loading the package:
+% \begin{quote}|\usepackage[appendix=|\meta{mode}|]{apxproof}|\end{quote}
+% \meta{mode} can take one of the following three values:
+% \begin{description}
+% \item[|append|] This is the default.
+% Appendix material gathered by \textsf{apxproof} is appended to
+% the main text.
+% \item[|inline|] In this mode, \textsf{apxproof} simply inline the
+% content along with the main text.
+% \item[|strip|] This mode functions similarly to |append| except that
+% the appendix is not appended at the end of the document. All appendix
+% material is therefore removed.
+% \end{description}
+%
+% \subsection{Customization}
+% \label{sec:customization}
+% \textsf{apxproof} provides a few macros that can be redefined (using
+% |\renewcommand|) to customize the appearance of the appendix:
+% \begin{description}
+% \item[\textbackslash|appendixsectionformat|\marg{number}\marg{title}]\DescribeMacro{\appendixsectionformat} is a macro
+% that indicates how to format the section titles in the Appendix, given
+% the number and title of the section in the main text. By
+% default, they appear as ``Proofs for Section~\meta{number}
+% (\meta{title})''.
+% \item[\textbackslash|appendixrefname|]\DescribeMacro{\appendixrefname} contains the heading that is displayed before
+% the bibliography. By default, this is ``References for the
+% Appendix''.
+% \item[\textbackslash|appendixbibliographystyle|]\DescribeMacro{\appendixbibliographystyle} contains the |.bst| bibliography
+% style that is used in the bibliography in appendix. By default, this is
+% |alpha|.
+% \item[\textbackslash|appendixbibliographyprelim|]\DescribeMacro{\appendixbibliographyprelim} contains arbitrary code that is executed
+% just before the production of the bibliography in appendix, which can
+% be used to configure the way it is displayed.
+% \end{description}
+%
+% \subsection{Advanced Commands}
+% We now describe a few advanced macros and environments, whose usage is limited to
+% special cases:
+% \begin{description}
+% \item[|nestedproof|]\DescribeEnv{nestedproof} is an environment that
+% can be used within a |proof| environment deferred in the appendix; this
+% is required because, for technical reasons, no |proof| environment can
+% be nested within a deferred |proof| environment.
+% \item[\textbackslash|noproofinappendix|]\DescribeMacro{\noproofinappendix}
+% can be used inside repeated theorems that are not followed by a
+% |proof| or |appendixproof| theorem; the point is to ensure that a further
+% |proof| environment cannot be mistakenly understood as a proof of the repeated
+% theorem. It should not be needed in most situations as
+% \textsf{apxproof} tries figuring out when a proof follows a repeated
+% theorem automatically, but may occasionally be needed in complex
+% scenarios.
+% \item[\textbackslash|nosectionappendix|]\DescribeMacro{\nosectionappendix}
+% is to be used inside a section that \emph{does} contain appendix material, but
+% for which a section in the appendix should not be created. This should
+% be rarely needed. When this command is present, appendix material is
+% appended to the end of the previously created section.
+% \end{description}
+% \section{Supported Document Classes}
+% Because \textsf{apxproof} modifies sectioning commands, bibliographies,
+% and proofs, it may not work straight away with arbitrary document classes.
+% It has currently been tested with and is supported for the following
+% document classes:
+% \begin{itemize}
+% \item \LaTeX{} standard document classes (e.g., |article.cls|)
+% \item \href{https://www.ctan.org/pkg/koma-script}{KOMA-Script}
+% (e.g., |scrartcl.cls|)
+% \item \href{https://www.acm.org/publications/proceedings-template}{ACM
+% SIG Proceedings} (e.g., |sig-alternate.cls|)
+% \item \href{https://www.springer.com/computer/lncs/lncs+authors}{
+% Springer's Lecture Notes in Computer Science} (e.g.,
+% |llncs.cls|)
+% \item
+% \href{https://www.dagstuhl.de/en/publications/lipics}{Schlo\ss{}
+% Dagstuhl's Leibniz International Proceedings in Informatics} (e.g.,
+% |lipics.cls|)
+% \end{itemize}
+% Other classes may work out of the box. Adding support for specific
+% classes is possible and can be requested from the
+% author of this package.
+% \section{Known Issues and Limitations}
+% We report here some issues we are currently aware of:
+% \begin{itemize}
+% \item When using \textsf{hyperref}, the appendix in the bibliography is
+% not hyperlinked. This is to avoid possible issues with multiply defined
+% bibliography entries.
+% \item |appendixproof|, |proof|, |toappendix| environments cannot be nested. This is a limitation of
+% the \textsf{fancyvrb} package that \textsf{apxproof} relies on. Note
+% the existence of the |nestedproof| environment for nested proofs.
+% \item \textsf{apxproof} is incompatible with a separate use of the
+% \textsf{fancyvrb} package. This is because \textsf{apxproof} redefines
+% some internal mechanisms of \textsf{fancyvrb}.
+% \end{itemize}
+%
+% Issues not listed here should be reported to the author.

+% \section{Implementation}
+% We now describe the entire code of the package, in a literate programming
+% fashion. Throughout the package, we use the |axp@| prefix to identify
+% local macros and environment names, which are not meant to be used by the final
+% user.
+% \subsection{Dependencies}
+% We first load a few package dependencies:
+% \begin{itemize}
+% \item \textsf{bibunits} to add a second bibliography for the appendix
+% material.
+%    \begin{macrocode}
+\RequirePackage{bibunits}
+%    \end{macrocode}
+% \item \textsf{environ} to easily define the repeated theorem
+% environments.
+%    \begin{macrocode}
+\RequirePackage{environ}
+%    \end{macrocode}
+% \item \textsf{etoolbox} to define simple toggles.
+%    \begin{macrocode}
+\RequirePackage{etoolbox}
+%    \end{macrocode}
+% \item \textsf{fancyvrb} for the bulk of the work of exporting appendix
+% material in an auxiliary file.
+%    \begin{macrocode}
+\RequirePackage{fancyvrb}
+%    \end{macrocode}
+% \item \textsf{ifthen} for easier comparison of character strings.
+%    \begin{macrocode}
+\RequirePackage{ifthen}
+%    \end{macrocode}
+% \item \textsf{kvoptions} to manage options passed to the package.
+%    \begin{macrocode}
+\RequirePackage{kvoptions}
+%    \end{macrocode}
+% \item \textsf{amsthm} for its |\newteorem| macro.
+% Some document classes (e.g., \textsf{lipics})
+% preload \textsf{amsthm}: this is fine, |\RequirePackage{amsthm}|
+% will simply have no effect. On the other hand, some other document
+% classes (e.g., \textsf{llncs} or \textsf{sig-alternate}) define a
+% |proof| environment that conflicts with \textsf{amsthm}, so we have to
+% undefine this environment before loading \textsf{amsthm}.
+%    \begin{macrocode}
+\@ifpackageloaded{amsthm}{
+  }{
+    \let\proof\undefined
+    \let\endproof\undefined
+  }
+\RequirePackage{amsthm}
+%    \end{macrocode}
+% \end{itemize}
+% \subsection{Option Processing}
+% Many names throughout the package use an arobase (|@|) to avoid name
+% conflict with user-defined names. To simplify the compilation of the
+% documentation, we simply make it a regular character in all the rest.
+%    \begin{macrocode}
+\makeatletter
+%    \end{macrocode}
+% \begin{macro}{\axp@appendix}
+% We setup the processing of options using \textsf{keyval} facilities;
+% the only declared option is named |appendix|, with a default value of
+% |append|:
+%    \begin{macrocode}
+\SetupKeyvalOptions{
+  family=axp,
+  prefix=axp@
+}
+\DeclareStringOption[append]{appendix}
+\ProcessLocalKeyvalOptions*
+%    \end{macrocode}
+% \end{macro}
+% We check that the value of the |appendix| option is valid, and add a
+% message to the compilation log.
+%    \begin{macrocode}
+\ifthenelse{\equal{\axp@appendix}{append}}{
+  \message{apxproof: Appendix material appended to the document}
+}{\ifthenelse{\equal{\axp@appendix}{strip}}{
+  \message{apxproof: Appendix material stripped}
+}{\ifthenelse{\equal{\axp@appendix}{inline}}{
+  \message{apxproof: Appendix material inlined within the document}
+}{
+  \errmessage{Error: unsupported option appendix=\axp@appendix for
+  package apxproof}
+}}}
+%    \end{macrocode}
+% \subsection{Macros Common to All Compilation Modes}
+% \begin{macro}{\newtheoremrep}
+% We define the high-level |\newtheoremrep| to have the same syntax as
+% \textsf{amsthm}'s |\newtheorem|. For this purpose, we need a little
+% trick to deal with the second optional argument, which is what
+% |\@oparg| is used for. |\axp@newtheoremrep| is defined differently
+% depending on the compilation mode
+%    \begin{macrocode}
+\newcommand\newtheoremrep[1]{%
+  \@oparg{\axp@newtheoremrep{#1}}[]%
+}
+%    \end{macrocode}
+% \end{macro}
+% \begin{environment}{proofsketch}
+% Simple |proofsketch| environment.
+%    \begin{macrocode}
+\newenvironment{proofsketch}
+  {\vskip3pt\noindent\textit{Proof sketch.} \upshape}
+  {\hfill\qed\vskip3pt}
+%    \end{macrocode}
+% \end{environment}  
+% \begin{macro}{\thmhead}  
+% We redefine AMS-\LaTeX{}'s |\thmhead| to use a format where the
+% repeated version of a theorem, using a theorem note, can look exactly
+% like the original version of the theorem and its theorem counter.
+%    \begin{macrocode}
+\def\thmhead#1#2#3{%
+  \thmname{#1}\thmnumber{\@ifnotempty{#1}{ }\@upn{#2}}%
+  \thmnote{ #3}}
+%    \end{macrocode}
+% \end{macro}  
+% \begin{macro}{\appendixrefname}
+% \begin{macro}{\appendixbibliographystyle}
+% \begin{macro}{\appendixbibliographyprelim}
+% \begin{macro}{\appendixsectionformat}
+% We provide sensible defaults for these three user-customizable macros.
+% Even though they are only useful in append mode, we define them for
+% all modes so that a |\renewcommand| works in all cases.
+%    \begin{macrocode}
+\newcommand{\appendixrefname}{References for the Appendix}
+\newcommand{\appendixbibliographystyle}{alpha}
+\newcommand{\appendixbibliographyprelim}{}
+\newcommand{\appendixsectionformat}[2]{Proofs for Section~#1 (#2)}
+%    \end{macrocode}
+% \end{macro}
+% \end{macro}
+% \end{macro}
+% \end{macro}
+% Finally, some class-specific behavior ensures that the theorems created by
+% |\newtheoremrep| appear with the correct style.
+% For now, only the styling for ACM document classes (e.g.,
+% \textsf{sig-alternate}) needs to be adapted.  
+%    \begin{macrocode}
+\ifdefined\@acmtitlebox
+  \newtheoremstyle{mystyle}
+    {3pt}
+    {3pt}
+    {\itshape}
+    {}
+    {\scshape}
+    {.}
+    {.5em}
+    {}
+  \theoremstyle{mystyle}
+\fi
+%    \end{macrocode}
+% \subsection{Inline Compilation Mode}
+%    \begin{macrocode}
+\ifthenelse{\equal{\axp@appendix}{inline}}{
+%    \end{macrocode}
+% \begin{macro}{\axp@newtheoremrep}
+% In inline mode, |\axp@newtheoremrep| undefines the existing
+% theorem environment if it has already been defined (e.g., by the
+% document class), invokes |\newtheorem| and creates a repeated theorem
+% environment that behaves exactly as the regular theorem environment.
+%    \begin{macrocode}
+  \def\axp@newtheoremrep#1[#2]#3{%
+    \expandafter\let\csname #1\endcsname\undefined
+    \expandafter\let\csname c@#1\endcsname\undefined
+    \newtheorem{#1}[#2]{#3}%
+    \NewEnviron{#1rep}[1][]{%
+      \begin{#1}[##1]\BODY\end{#1}%
+    }
+  }
+%    \end{macrocode}
+% \end{macro}  
+% \begin{environment}{inlineproof}
+% \begin{environment}{nestedproof}
+% \begin{environment}{appendixproof}
+% In inline mode, these environments behave like the regular |proof|
+% environment.
+%    \begin{macrocode}
+  \let\inlineproof\proof
+  \let\endinlineproof\endproof
+  \let\nestedproof\proof
+  \let\endnestedproof\endproof
+  \let\appendixproof\proof
+  \let\endappendixproof\endproof
+%    \end{macrocode}
+% \end{environment}  
+% \end{environment}  
+% \end{environment}  
+% \begin{environment}{toappendix}
+% \begin{macro}{\noproofinappendix}
+% \begin{macro}{\nosectionappendix}
+% In inline mode, this environment and these macros are no-ops.  
+%    \begin{macrocode}
+  \newenvironment{toappendix}{}{}
+  \let\noproofinappendix\relax
+  \let\nosectionappendix\relax
+%    \end{macrocode}
+% \end{macro}
+% \end{macro}  
+% \end{environment}  
+%    \begin{macrocode}
+} 
+%    \end{macrocode}
+% \subsection{Append or Strip Compilation Modes}
+%    \begin{macrocode}
+{
+%    \end{macrocode}
+% We now deal with the case where \textsf{apxproof} really does something
+% useful: either append the appendix material to the document, or strip
+% it entirely.
+% \bigskip
+%    \subsubsection{Auxiliary File for the Appendix}  
+% \begin{macro}{\axp@proofsfile}  
+% We open a new auxiliary file, with extension |.axp|, where the appendix
+% material will be dumped.  
+%    \begin{macrocode}  
+  \newwrite\axp@proofsfile
+  \immediate\openout\axp@proofsfile=\jobname.axp
+%    \end{macrocode}  
+% \end{macro}  
+% \begin{environment}{proof}
+% \begin{macro}{\section}
+% At the beginning of this file, we make |@| a regular character (since
+% it will be used in several places for internal names) and reestablish the original definition of
+% the |proof| environment and the |\section| macro.
+%    \begin{macrocode}  
+  \immediate\write\axp@proofsfile{%
+    \noexpand\makeatletter
+    \noexpand\let\noexpand\proof\noexpand\axp@oldproof

+    \noexpand\let\noexpand\section\noexpand\axp@oldsection
+  }
+%    \end{macrocode}  
+% \end{macro}  
+% \end{environment}  
+% \begin{macro}{\FVB@VerbatimOut}  
+% \begin{macro}{\FVE@VerbatimOut}  
+% We modify the internal behavior of the \textsf{fancyvrb} package to
+% write to the |\axp@proofsfile|, without closing it and re-opening it
+% on every write.  
+%    \begin{macrocode}  
+  \def\FVB@VerbatimOut{%

+    {\endVerbatimOut}
+%    \end{macrocode}  
+% \end{environment}
+%    \subsubsection{Definition of New Theorems}  
+% \begin{macro}{axp@seenreptheorem}
+% Used to indicate whether a repeated theorem was just typeset, without
+% its proof.
+%    \begin{macrocode}  
+  \newtoggle{axp@seenreptheorem}
+%    \end{macrocode}  
+% \end{macro}  
+% \begin{macro}{axp@rpcounter}
+% Sequentially incremented for every repeated theorem, used to create labels.
+%    \begin{macrocode}  
+  \newcounter{axp@rpcounter}
+%    \end{macrocode}  
+% \end{macro}  
+% \begin{macro}{axp@newtheoremrep}
+% When called with first argument |foobar|, we first undefine the existing
+% |foobar| environment (and its counter) if it has already been defined (e.g., by the
+% document class), then invoke |\newtheorem| for the regular version
+% of the theorem |foobar| (patching the |\begin{foobar}| so as not to
+% expect a proof in the appendix) and |\newtheorem*| for an internal version |axp@foobarrp| that
+% will be used in the appendix to restate the existing theorem.
+%    \begin{macrocode}  
+  \def\axp@newtheoremrep#1[#2]#3{%
+    \expandafter\let\csname #1\endcsname\undefined
+    \expandafter\let\csname c@#1\endcsname\undefined
+    \newtheorem{#1}[#2]{#3}%
+    \expandafter\pretocmd\csname #1\endcsname{\noproofinappendix}{}{}%
+    \newtheorem*{axp@#1rp}{#3}%
+%    \end{macrocode}  
+% We then define a |foobarrep| environment that increments the
+% |axp@rpcounter| and typeset the regular |foobar| theorem with a label
+% derived from the counter.    
+%    \begin{macrocode}  
+    \NewEnviron{#1rep}[1][]{%
+      \addtocounter{axp@rpcounter}{1}%
+      \begin{#1}[##1]\label{axp@r\roman{axp@rpcounter}}\BODY\end{#1}%
+%    \end{macrocode}  
+% We set the |axp@seenreptheorem| toggle to indicate that we are looking
+% for the proof of the theorem, then store in a macro the content of the
+% theorem's body.
+%    \begin{macrocode}  
+      \global\toggletrue{axp@seenreptheorem}%
+      \global\expandafter\let\csname rplet\roman{axp@rpcounter}%
+                             \endcsname
+      \BODY
+%    \end{macrocode}  
+% Possibly after starting a new appendix section if needed, we typeset a
+% repeated version of the theorem using the |axp@foobarrp| environment
+% and a reference to the previously defined label.
+% We ignore any use of |\label| in this environment to avoid multiply
+% defined labels.
+%    \begin{macrocode}  
+      \axp@writesection%
+      \immediate\write\axp@proofsfile{%
+        \noexpand\begin{axp@#1rp}
+          [\noexpand\ref{axp@r\roman{axp@rpcounter}}%
+           \@ifnotempty{##1}{\noexpand##1}]%
+          \noexpand\let\noexpand\label\noexpand\@gobble%
+          \expandafter\noexpand\csname rplet\roman{axp@rpcounter}%
+                               \endcsname
+        \noexpand\end{axp@#1rp}
+      }
+    }
+  }
+%    \end{macrocode}  
+% \end{macro}  
+%    \subsubsection{Proof Environments}  
+% \begin{environment}{axp@oldproof}
+%   We save the definition of the existing |proof| environment.
+%    \begin{macrocode}  
+  \let\axp@oldproof\proof
+  \let\endaxp@oldproof\endproof
+%    \end{macrocode}  
+% \end{environment}
+% \begin{macro}{\noproofinappendix}
+%   Utility macro that toggles |axp@seenreptheorem| to false.
+%    \begin{macrocode}  
+  \newcommand\noproofinappendix{%
+    \global\togglefalse{axp@seenreptheorem}%
+  }
+%    \end{macrocode}  
+% \end{macro}
+% \begin{environment}{appendixproof}
+% We dump the content of this in appendix, within an original |proof|
+% environment, possibly after creating a new appendix section.
+%    \begin{macrocode}  
+  \newenvironment{appendixproof}
+    {%
+      \axp@writesection
+      \immediate\write\axp@proofsfile{%

+% This environment either puts the proof in appendix, if we are after a repeated
+% theorem without its proof, or inlines it otherwise.

+% \begin{environment}{inlineproof}
+% \begin{environment}{nestedproof}
+% These two environments are synonyms for the original |proof|

+%    \subsubsection{Section Management}  
+% \begin{macro}{axp@seccounter}
+% Sequentially incremented for every section, used to create labels.
+%    \begin{macrocode}  
+  \newcounter{axp@seccounter}
+%    \end{macrocode}  
+% \end{macro}  
+% \begin{macro}{\axp@sectitle}
+% Saves the title of the last encountered section.
+%    \begin{macrocode}  
+  \def\axp@sectitle{}
+%    \end{macrocode}  
+% \end{macro}  
+% \begin{macro}{\axp@section}  
+% \begin{macro}{\axp@@ssection}  
+% \begin{macro}{\axp@@section}  
+% This command behaves similarly to |\axp@oldsection|, except that it first
+% tests whether a |\section| follows, and if so, does not produce
+% anything. This is useful to avoid producing empty sections in the
+% appendix. As usual, we have to process starred and unstarred version
+% separately.
+%    \begin{macrocode}  
+  \def\axp@section{\@ifstar\axp@@ssection\axp@@section}
+  \def\axp@@ssection#1{%
+    \@ifnextchar\section{}{\axp@oldsection*{#1}}%
+  }
+  \def\axp@@section#1{%
+    \@ifnextchar\section{}{\axp@oldsection{#1}}%
+  }
+%    \end{macrocode}  
+% \end{macro}  
+% \end{macro}  
+% \end{macro}  
+% \begin{macro}{\axp@oldsection}
+% \begin{macro}{\section}
+% \begin{macro}{\@section}
+% \begin{macro}{\@@section}
+% We redefine the |\section| command to create a label based on
+% |axp@seccounter| and to store its title in |\axp@sectitle|. Two definitions are necessary to cover the
+% starred and unstarred use of |\section|, though most likely the former
+% is not going to be used (since no section number will appear to refer
+% to that section in the appendix).
+%    \begin{macrocode}
+  \let\axp@oldsection\section
+  \def\section{\@ifstar\@section\@@section}
+  \def\@section#1{%
+    \global\edef\axp@sectitle{#1}%
+    \axp@oldsection*{#1}%
+    \addtocounter{axp@seccounter}{1}%
+    \label{axp@s\roman{axp@seccounter}}%
+  }
+  \def\@@section#1{%
+    \global\edef\axp@sectitle{#1}%
+    \axp@oldsection{#1}%
+    \addtocounter{axp@seccounter}{1}%
+    \label{axp@s\roman{axp@seccounter}}%
+  }
+%    \end{macrocode}  
+% \end{macro}
+% \end{macro}
+% \end{macro}
+% \end{macro}
+% \begin{macro}{\nosectionappendix}
+% We remove the current section title, to indicate no section should be
+% created in the appendix.
+%    \begin{macrocode}  
+  \newcommand{\nosectionappendix}{
+    \global\def\axp@sectitle{}%
+  }
+%    \end{macrocode}  
+% \end{macro}
+% \begin{macro}{\axp@writesection}
+% If |\axp@sectitle| is not empty, we create
+% a new section in the appendix, referring to the main text section.
+%    \begin{macrocode}  
+  \newcommand\axp@writesection{%
+    \ifx\axp@sectitle\@empty
+    \else
+      \immediate\write\axp@proofsfile{%
+        \noexpand\def\noexpand\axp@tmp{%
+          \noexpand\ref{axp@s\roman{axp@seccounter}}
+        }
+        \noexpand\axp@section{%
+          \noexpand\appendixsectionformat{\protect\noexpand\axp@tmp}%
+                                         {\axp@sectitle}%
+        }%
+      }%
+      \nosectionappendix
+    \fi
+  }
+%    \end{macrocode}  
+% \end{macro}
+%    \subsubsection{Append Compilation Mode}  
+%    \begin{macrocode}  
+  \ifthenelse{\equal{\axp@appendix}{append}}{
+%    \end{macrocode}  
+% \begin{macro}{\axp@oldbibliography}    
+% \begin{macro}{\bibliography}    
+% Thanks to \textsf{bibunits}'s |\defaultbibliography| macro, we set the appendix
+% bibliography source to be the same as that of the main text.    
+%    \begin{macrocode}  
+    \let\axp@oldbibliography\bibliography
+    \renewcommand\bibliography[1]{%
+      \defaultbibliography{#1}%
+      \axp@oldbibliography{#1}%
+    }
+%    \end{macrocode}  
+% \end{macro}
+% \end{macro}
+% After the end of the main text, we add the appendix (on a new page, set
+% in single-column mode) within a |bibunit| environment so as to typeset
+% a separate bibliography for the appendix.
+%    \begin{macrocode}
+    \AtEndDocument{
+      \clearpage\onecolumn\appendix
+      \begin{bibunit}[\appendixbibliographystyle]
+        \immediate\closeout\axp@proofsfile
+        \input{\jobname.axp}
+        \renewcommand{\refname}{\appendixrefname}
+        \appendixbibliographyprelim
+        \putbib
+      \end{bibunit}
+    }
+%    \end{macrocode}  
+%    \begin{macrocode}  
+  }{}
+%    \end{macrocode}
+% \subsubsection{Class-Specific Behavior}    
+% We conclude with some class-specific behavior.
+% \begin{macro}{\@getcl@ss}
+% \begin{macro}{\@getclass}
+% \begin{macro}{\@currentclass}
+% We first use a little trick to store the document class in
+% macro |\@currentclass|, from
+% \url{http://tex.stackexchange.com/a/43541}.
+%    \begin{macrocode}
+  \def\@getcl@ss#1.cls#2\relax{\def\@currentclass{#1}}
+  \def\@getclass{\expandafter\@getcl@ss\@filelist\relax}
+  \@getclass
+%    \end{macrocode}
+% \end{macro}
+% \end{macro}
+% \end{macro}
+% \paragraph{ACM Document Classes}
+%    \begin{macrocode}
+  \ifdefined\@acmtitlebox
+%    \end{macrocode}
+% \begin{macro}{\thebibliography}
+% \begin{macro}{\refname}
+% \begin{macro}{\appendixrefname}
+% The section title of the bibliography is in uppercase in these document
+% classes. In addition, the |\thebibliography| macro hard-codes twice
+% the section title, so we un-hardcode it so that it can be modified
+% in the appendix.    
+%    \begin{macrocode}
+    \patchcmd{\thebibliography}{References}{\protect\refname}{}{}
+    \patchcmd{\thebibliography}{References}{\protect\refname}{}{}
+    \newcommand{\refname}{REFERENCES}
+    \renewcommand{\appendixrefname}{REFERENCES FOR THE APPENDIX}
+%    \end{macrocode}
+% \end{macro}
+% \end{macro}
+% \end{macro}
+% \begin{macro}{\section}
+% \begin{macro}{\@@section}
+% These document classes redefine |\section| in a weird way, adding
+% the possibility of an optional argument. We redefine them in a sane
+% way.    
+%    \begin{macrocode}
+    \def\section{\@ifstar\@section{\@dblarg{\@@section}}}
+    \def\@@section[#1]#2{%
+      \global\edef\axp@sectitle{#2}%
+      \axp@oldsection{#2}%
+      \addtocounter{axp@seccounter}{1}%
+      \label{axp@s\roman{axp@seccounter}}%
+    }
+%    \end{macrocode}
+% \end{macro}
+% \end{macro}
+%    \begin{macrocode}
+  \fi
+%    \end{macrocode}
+% \paragraph{\textsf{lipcs}}
+%    \begin{macrocode}
+   \ifthenelse{\equal{\@currentclass}{lipics}}{
+%    \end{macrocode}
+% \begin{macro}{\appendixbibliographyprelim}  
+% The default bibliography in the \textsf{lipics} document class
+% formatting is not compatible with the
+% \textsf{alpha} bibliography style. We fix this here.
+%    \begin{macrocode}
+    \renewcommand{\appendixbibliographyprelim}{%
+      \global\let\@oldbiblabel\@biblabel
+      \def\@biblabel{\hspace*{-2em}\small\@oldbiblabel}%
+    }    
+%    \end{macrocode}
