+The LaTeX Project Public License
+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
+
+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.

+\title{\textsf{overlays} -- incremental slides}
+\author{Andreas Nolda}
+\date{2016/09/30 (v.\,2.0)}
+\maketitle
+
+\noindent The \textsf{overlay} package allows to write presentations with
+incremental slides. It does not presuppose any specific document class. Rather,
+it is a lightweight alternative to full-fledged presentation classes like
+\textsf{beamer}.
+
+In the following, every single state of a incremental slide will be called an
+\emph{overlay} of that slide.
+
+\section{User interface}
+
+\DescribeMacro{overlays}
+\DescribeMacro{fragileoverlays}
+For incremental slides, the following environments are provided:
+\begin{quote}
+|\begin{overlays}{|\meta{total overlay number}|}| \\
+\meta{slide content} \\
+|\end{overlays}|
+\end{quote}
+\begin{quote}
+|\begin{fragileoverlays}{|\meta{total overlay number}|}| \\
+\meta{slide content} \\
+|\end{fragileoverlays}|
+\end{quote}
+The |fragileoverlays| environment should be used for incremental slides with
+verbatim content.
+
+Note that the slide content should fit on a single page.
+
+\DescribeMacro{\alert}
+\DescribeMacro{\visible}
+\DescribeMacro{\only}
+In the slide content, the following commands can be used in order
+to specify the content of the overlays:
+\begin{quote}
+|\alert{|\meta{overlay specification}|}{|\meta{content}|}|
+\end{quote}
+\begin{quote}
+|\visible{|\meta{overlay specification}|}{|\meta{content}|}|
+\end{quote}
+\begin{quote}
+|\only{|\meta{overlay specification}|}{|\meta{content}|}|
+\end{quote} Overlay specifications are either single numbers like |1|, sequences
+of numbers like |1,4|, or ranges of numbers like |1-4| or |1-|.
+
+The |\alert| command highlights its content on the specified overlays with the
+|alert| color, which may be redefined by means of the |\definecolor| command.
+
+The |\visible| command uncovers its content on the overlays which are specified
+in the overlay specification. On unspecified overlays, the content still takes
+up space, being rendered in the |background| color, which, by default, is white.
+
+The content of the |\only| command is also uncovered on the overlays specified
+in the overlay specification, but is absent from unspecified overlays and does
+not take up space there.
+
+\section{Known limitations}
+
+The |\alert|, |\visible|, and |\only| commands must not contain verbatim
+commands or environments. They may be used in the content of the |alltt|
+environment, though.
+
+\section{Credits}
+
+The code of the \textsf{overlays} package is inspired by Matthias Meister's
+\textsf{present} package.
+
+In addition, it uses an algorithm by Martin Scharrer for testing numbers in
+numerical ranges (cf. \url{http://tex.stackexchange.com/q/19000/}).
+
+The code for processing overlays with verbatim content is taken from the
+\textsf{texpower} package, which in turn took it from Till Tantau's
+\textsf{beamer} package.

+\begin{fragileoverlays}{6}
+\subsubsection*{Overlays}
+The \textrm{overlays} package allows to write presentations with incremental
+slides. It does not presuppose any specific document class. Rather, it is a
+lightweight alternative to full-fledged presentation classes like
+\href{http://www.ctan.org/pkg/beamer}{\textrm{beamer}}.
+
+\visible{2-}{Every single state of a incremental slide will called an
+\emph{overlay} of that slide.}
+
+\visible{3-}{For incremental slides, the following environment is provided:}
+\begin{quote}
+\begin{alltt}
+\visible{3-}{\alert{3}{\textbackslash{}begin\{overlays\}\{\meta{total overlay number}\}
+\alert{4-}{\meta{slide content}}
+\textbackslash{}end\{overlays\}}}
+\end{alltt}
+\end{quote}
+
+\visible{4-}{In the slide content, the following commands can be used in order
+to specify the content of the overlays:
+\only{4}{\texttt{\textbackslash{}alert}.}%
+\only{5}{\texttt{\textbackslash{}visible}.}%
+\only{6}{\texttt{\textbackslash{}only}.}}
+\end{fragileoverlays}
+\clearpage
+
+% Slide with verbatim content.
+
+\begin{fragileoverlays}{6}
+\subsubsection*{Highlightning}
+For highlightning some content, the \textrm{overlays} package provides
+following command:
+\begin{quote}
+\begin{alltt}
+\alert{1}{\textbackslash{}alert\{\alert{2-5}{\meta{overlay specification}}\}\{\meta{content}\}}
+\end{alltt}
+\end{quote}
+
+\visible{2-}{Overlay specifications are either
+\alert{3}{single numbers},
+\alert{4}{sequences of numbers}, or
+\alert{5}{ranges of numbers}.
+\visible{3-}{For example:
+\begin{itemize}
+\item{} \alert{3}{\texttt{1}}
+\visible{4-}{\item{} \alert{4}{\texttt{1,4}}}
+\visible{5-}{\item{} \alert{5}{\texttt{1-4}}
+\item{} \alert{5}{\texttt{1-}}}
+\end{itemize}}}
+
+\visible{6}{The \texttt{alert} color is red by default and can be changed to,
+say, \alert{6}{magenta} as follows:
+\begin{quote}
+\begin{alltt}
+\textbackslash{}definecolor\{alert\}\{rgb\}\{\alert{6}{0.7,0.15,0.35}\}
+\end{alltt}
+\end{quote}}
+\end{fragileoverlays}
+\clearpage
+
+\begin{fragileoverlays}{5}
+\subsubsection*{Visibility}
+The visibility of content is specified by means of the following commands:
+\begin{quote}
+\begin{alltt}
+\alert{1-3}{\textbackslash{}visible\{\meta{overlay specification}\}\{\meta{content}\}}
+\end{alltt}
+\end{quote}
+\begin{quote}
+\begin{alltt}
+\alert{1,4-}{\textbackslash{}only\{\meta{overlay specification}\}\{\meta{content}\}}
+\end{alltt}
+\end{quote}
+
+\only{2,3}{The \texttt{\textbackslash{}visible} command uncovers its content on
+the overlays which are specified in the overlay specification.}
+
+\only{3}{On unspecified overlays, the content is hidden, but still takes up
+space. Technically speaking, it is rendered in the \texttt{background} color,
+which, by default, is white.}%
+\only{4-}{
+The \texttt{\textbackslash{}only} command also uncovers its content on the
+overlays specified in the overlay specification.
+
+The content is absent from unspecified overlays and does not take up space
+there.}
+
+\only{5}{This is particularly useful for alternating content.}
+\end{fragileoverlays}
+\clearpage
+
+\begin{fragileoverlays}{3}
+\subsubsection*{Verbatim content}
+For incremental slides with verbatim content, the following environment should
+be used instead of the \texttt{overlay} environment:
+\begin{quote}
+\begin{alltt}
+\alert{1}{\textbackslash{}begin\{fragileoverlays\}\{\meta{total overlay number}\}
+\meta{slide content}
+\textbackslash{}end\{fragileoverlays\}}
+\end{alltt}
+\end{quote}
+
+\visible{2-}{Note that the \alert{2,3}{\texttt{\textbackslash{}alert}},
+\alert{2,3}{\texttt{\textbackslash{}visible}}, and
+\alert{2,3}{\texttt{\textbackslash{}only}} commands themselves must not contain
+verbatim commands or environments.\visible{3}{ They may be used in the content
+of the \texttt{alltt} environment of the
+\href{http://www.ctan.org/pkg/alltt}{\textrm{alltt} package}, though.}}
+\end{fragileoverlays}
+\clearpage
+
+\begin{overlays}{6}
+\subsubsection*{Caveats}
+The package expects that the slide content in the \texttt{overlays} environment
+fits on a single page. This can be ensured by means of
+\texttt{\textbackslash{}clearpage} commands before or after the environment.
+
+\visible{2-}{The \texttt{page} counter is not incremented between overlays.
+Other counters may give rise to unexpected results.}
+
+\visible{3-}{In the \texttt{tabular} environment, the
+\alert{3}{\texttt{\textbackslash{}alert}},
+\alert{4}{\texttt{\textbackslash{}visible}} and
+\alert{5}{\texttt{\textbackslash{}only}} commands have to be put into braces:
+\begin{quote}
+\begin{tabular}[t]{ll}
+outside \texttt{tabular} & inside \texttt{tabular} \\\hline
+{\alert{3}{\texttt{\textbackslash{}alert\{\ldots\}\{\ldots\}}}} &
+{\alert{3}{\texttt{\{\textbackslash{}alert\{\ldots\}\{\ldots\}\}}}} \\
+{\visible{4-}{{\alert{4}{\texttt{\textbackslash{}visible\{\ldots\}\{\ldots\}}}}}} &
+{\visible{4-}{{\alert{4}{\texttt{\{\textbackslash{}visible\{\ldots\}\{\ldots\}\}}}}}} \\
+{\visible{5-}{{\alert{5}{\texttt{\textbackslash{}only\{\ldots\}\{\ldots\}}}}}} &
+{\visible{5-}{{\alert{5}{\texttt{\{\textbackslash{}only\{\ldots\}\{\ldots\}\}}}}}}
+\end{tabular}
+\end{quote}}
+\visible{6-}{In addition, make sure not to include the cell delimiter
+\texttt{\&} or the row delimiter \texttt{\textbackslash{}\textbackslash{}} into
+the content of these commands.}
+\end{overlays}
+\clearpage
+
+\begin{overlays}{3}
+\subsubsection*{Credits}
+The code of the \textrm{overlays} package is inspired by
+\href{http://www.ctan.org/pkg/present}{Matthias Meister's \textrm{present}
+package}.
+
+\visible{2-}{In addition, it uses
+\href{http://tex.stackexchange.com/q/19000/}{an algorithm by Martin Scharrer}
+for testing numbers in numerical ranges.}
+
+\visible{3}{The code for processing overlays with verbatim content is taken from
+the \textrm{texpower} package, which in turn took it from Till Tantau's
+\textrm{beamer} package.}
