% \section{Introduction}
%
% The |todonotes| package makes three commands available to the
% user: |\todo[]{}|, |\missingfigure{}| and |\listoftodos|.
% |\todo[]{}| and |\missingfigure{}| makes it possible to insert
% notes in your document about things that has to be done later
% (todonotes \ldots).
% I developed the basic functionality of the package while I worked
% on my bachelor project.
% 
%
%
% \subsection{Usage}
%
% \DescribeMacro{\todo}
% My \index{\todo}most common usage of the todonotes package, is to 
% insert an uncustomized todonotes somewhere in a latex document. 
% An example of this usage is the command 
%
% |\todo{Make a cake \ldots}|, 
% 
% \noindent
% which renders like\todo{Make a cake \ldots}.
% The |\todo| command has this structure: 
% |\todo|\oarg{options}\marg{todo text}.
% The |todo text| is the text that will be shown in the todonote and
% in the list of todos. The optional argument |options|, allows the
% user to customize the appearance of the inserted todonotes.
% For a description of all the options see section
% \ref{subsecTodoOptions}.
%
%
% \DescribeMacro{\missingfigure}
% The |\missingfigure| command inserts an image containing an 
% attention sign and the given text.
% The command takes only one argument
% |\missingfigure|\marg{text}, a text string that could
% describe what the figure should consist of.
% An example of its usage could be 
%
% |\missingfigure{Make a sketch of the structure of a trebuchet.}| 
%
% \noindent
% which renders like.
%
% \missingfigure{Make a sketch of the structure of a trebuchet.}
%
%
% \DescribeMacro{\listoftodos}
% The |\listoftodos| command inserts a list of all the todos in the
% current document. |\listoftodos| takes no arguments.
% For this document the list of to--do's looks like.
% \listoftodos

% \subsection{Package options}
% \label{subsecPackageOptions}
% \DescribeMacro{disable}
% If the option |disable| is passed to the package, the macros
% usually defined by the package (|\todo|, |\listoftodos| and
% |\missingfigure|) are defined as macros with no effect, and thus
% all inserted notes are removed.
%
% \DescribeMacro{danish}
% \DescribeMacro{german}
% Use the danish or german translations of the text strings 
% ''List of todos'' and ''Missing figure''.
% The default is to use none of these options, which results in
% english text strings.
% 
% \DescribeMacro{colorinlistoftodos}
% Adds a small colored square in front of all items in the Todo
% list. The color of the square is the same as the fill color of the
% inserted todonote.
% This can be usefull if there are different types of todos 
% (insert reference, explain in detail, \ldots) where the color of
% the inserted todonote marks the type of todo.
%
% \DescribeMacro{color}
% \DescribeMacro{backgrouncolor}
% \DescribeMacro{linecolor}
% \DescribeMacro{bordercolor}
% These options sets the default colors for the todo command.
% There is three colors that can be specified. The border color
% (default |bordercolor=black|) around the inserted text, the color
% behind the inserted text (default |backgroundcolor=orange|) and
% the color of the line connecting the inserted textbox with the
% current location in the text (default |linecolor=orange|). 
% Setting the |color| option to |val| passes this value on to the 
% background and line color options.
% The specified colors must be valid according to the 
% |xcolor| package.
% 
% \DescribeMacro{textwidth}
% |textwidth=length| sets the width of a todo item in the margin to
% |length|. The width of inline todonotes will allways be the same 
% as the current line width.
%
% \DescribeMacro{prependcaption}
% The |prependcaption| option triggers a special behaviour of the
% |caption=val| option for the todo command, where the given value
% |val| is inserted in the inserted todonote.
% 
% \DescribeMacro{dvistyle}
% When a document with todonotes is compiled with plain latex (to a
% dvi-file), there is an issue with the visual
% appearance\footnote{The problem is placement of text inside the
% colored boxes.}.
% The option |dvistyle| changes the appearance of the inserted
% todonotes to avoid this problem.
%
% 
%
% \subsection{Options for the todo command}
% \label{subsecTodoOptions}
% There are several options that can be given to the |\todo|
% command. All the options are described here and often I have
% included examples of the change in visual appearance.
%
% \DescribeMacro{color}
% \DescribeMacro{backgroundcolor}
% \DescribeMacro{linecolor}
% \DescribeMacro{bordercolor}
% These options set the color that is used in the current todo
% command.
% The color classes is the same as used in the color package
% options, see section \ref{subsecPackageOptions}.
% Default values can be set by the color
% options when the todonotes package is loaded.
% \todo[color=green!40]{And a green note}
% The todo notes inserted in this paragraph is created with the
% command
% |\todo[color=green!40]{And a green note}|.
% The color of the inserted note could be used to mark different
% types of tasks (insert references, explain something in detail,
% \ldots), this could be streamlined by defining new commands like
% below.
% \begin{verbatim}
% \newcommand{\insertref}[1]{\todo[color=green!40]{#1}}
% \newcommand{\explainindetail}[1]{\todo[color=red!40]{#1}}
% \end{verbatim}
% An example that uses all of the color options is given below
% \todo[linecolor=green!70!white, backgroundcolor=blue!20!white,
% bordercolor=red]{Anything but default colors}.
% \begin{verbatim}
% \todo[linecolor=green!70!white, backgroundcolor=blue!20!white,
% bordercolor=red]{Anything but default colors}.
% \end{verbatim}
%
%
% \DescribeMacro{line / noline}
% If you want to get rid of the line connecting the inserted note
% with the place in the text where the note occurs in the latex
% code, the option |noline| can be used.
% \todo[noline]{A note with no line connecting it to the placement
% in the original text.}
% |\todo[noline]{A note with no line ...}|
% \vspace{1.0cm}
% 
%
% \DescribeMacro{inline / noinline}
% It is possible to place a todonote inside the text instead of
% placing it in the margin, this could be desireable if the text in
% the note has a considerable length.
% |\todo[inline]{A todonote placed in the text}|
% \todo[inline]{A todonote placed in the text}

% \begin{wrapfigure}[1]{r}[20mm]{40mm}
% \begin{tikzpicture}
% \draw[red] (0, 0) circle(0.45);
% \draw[green] (1, 0) circle(0.45);
% \draw[blue] (2, 0) circle(0.45);
% \end{tikzpicture}
% \caption{A text explaining the image.
% \todo[inline]{Fill those circles \ldots}}
% \end{wrapfigure}
% Another usage for the inline option is when you want to add a
% todonote to a figure caption.
%
% \begin{verbatim}
% \begin{wrapfigure}{r}[20mm]{40mm}
% \begin{tikzpicture}
% \draw[red] (0, 0) circle(0.45);
% \draw[green] (1, 0) circle(0.45);
% \draw[blue] (2, 0) circle(0.45);
% \end{tikzpicture}
% \caption{A text explaining the image.
% \todo[inline]{Fill those circles \ldots}}
% \end{wrapfigure}
% \end{verbatim}
%
% \DescribeMacro{size}
% |size=val| changes the size of the text inside the todonote.
% The commands used to create the notes below are \\ \noindent
% |\todo[size=\Large]{A note with a large fontsize.}|
% and \\ \noindent
% |\todo[inline, size=\tiny]{Note with very small fontsize.}|.
% \todo[size=\Large]{A note with a large fontsize.}
% \todo[inline, size=\footnotesize]{Note with very small fontsize.}
%
% \DescribeMacro{list / nolist}
% When the option |nolist| is given, the todo item will not appear in
% the list of todos.
%
% \DescribeMacro{caption}
% The |caption| option enables the user to specify a short
% description of the todonote that are inserted in the list of
% todos instead of the full todonote text.
% \todo[caption={Short note}]{A very long and tedious note that
% cannot be on one line in the list of todos.}
% \begin{verbatim}
% \todo[caption={Short note}]{A very long and tedious note that
% cannot be on one line in the list of todos.}.
% \end{verbatim}
% The effect of this option is altered with the package option
% |prependcaption|.
%
%
% \subsection{Options for the missingfigure command}
% Currently the missingfigure command takes no optional arguments.
% 
% \subsection{Options for the listoftodos command}
% Currently the listoftodos command takes no optional arguments.
% 
% \subsection{Known issues}
% \subsubsection{Package loading order}
% The todonotes package requires the following packages.
% \begin{multicols}{2}
% \begin{itemize}
% \item ifthen
% \item xkeyval
% \item hyperref
% \item xcolor
% \item tikz
% \item calc
% \item graphicx (is loaded via the tikz package)
% \end{itemize}
% \end{multicols}
% \noindent
% When todonotes are loaded in the preamble, the package checks
% if these packages all are loaded. If that is not the case it loads
% the missing packages with no options given.
% If you want to give some specific options to some of these
% packages, you have to load them \emph{before} the todonotes
% package, otherwise you will get an ''Option clash'' error when
% latex works on the document.
%
% \subsubsection{Wrapping of long lines in list of todos}
% When a document is compiled with latex (and not pdflatex) long
% items in the list of todos are not wrapped into several lines, and
% do instead continue to the right out of the page.
% 
%
% \subsection{Things to improve}
% This is a list of things I consider to improve sometime in the
% future. I havent been done yet as I lack the time or skills to
% implement them.
% Patches with implementations of these tasks will be appreciated
% and might be included in the package if it will improve the
% package quality.
%
%
% \subsubsection{Owner information}
% Option for the todo command.
% \begin{verbatim}
% \todo[owner={Fabrice}]{Stuff}
% \end{verbatim}
% Add info on who ''owns'' the current todo. 
% Idea: Fabrice Niessen
%
%
% \subsubsection{Due date}
% Option for the todo command.
% \begin{verbatim}
% \todo[due=2008-12-07]{Stuff}
% \end{verbatim}
% Add info on when the current todo is due.
% Might be enhanced by a time line of the todos that have a due date
% assigned.
% Idea: Fabrice Niessen
%
%
% \subsubsection{Mark accomplished todos}
% \begin{verbatim}
% \todo[done]{Stuff}
% \end{verbatim}
% Idea: Fabrice Niessen
%
%
% \subsubsection{Enumeration of the todo notes}
% Add counters to the inserted notes.
% Idea: Henrik
%
%
%
% 
% 
% \subsection{Usage methods}
% In this section I have collected some different methods to use the
% |todonotes| package.
%
%
% \subsubsection{Define new commands with fixed options}
% Often there is a need for marking different classes of things to
% do (add reference, rewrite, \ldots).
% One way to do this, is to define some new commands as shown below
% (idea from Florent B.).
% \begin{verbatim}
% \newcommand{\addref}{\todo[color=red!40]{Add reference.}}
% \newcommand{\rewrite}[1]{\todo[color=green!40]{#1}}
% \end{verbatim}
% To distinguish between the different types of todos, the
% |todonotes| package can be loaded with the |colorinlistoftodos|
% option, which adds small colored squares to the list of todos.
% \begin{verbatim}
% \usepackage[colorinlistoftodos]{todonotes}
% \end{verbatim}
% 
% 
%
% \subsubsection{Combination with the fixme package}
%
% Thomas Arildsen has mailed me this use case. Check the
% documentation for the |fixme| package, as the code below relies
% directly on it (the |\FDUser| command is augumented when
% |\begin{document}| is reached).
% \begin{verbatim}
% \usepackage[user,nomargin]{fixme}
% \usepackage{todonotes}
% \newcommand{\FXUser}[2]{\todo[inline,size=\small]{{\bfseries #1:} #2}}
% \end{verbatim}
%
%
%
% \subsubsection{Altering the linespacing of todonotes}
%
% The |setspace| package lets you alter the line spacing of smaller
% sections of your document. The primary construct is the
% |spacing| environment, which is demonstrated below.
% \begin{verbatim}
% \begin{spacing}{0.5}
% Some lines with a decreased line spacing. This is accomplished
% using the setspace package that is included in standard latex
% distributions.
% \end{spacing}
% \end{verbatim}
% \begin{spacing}{0.5}
% Some lines with a decreased line spacing. This is accomplished
% using the setspace package that is included in standard latex
% distributions.
% \end{spacing}
%
% \vspace{0.25cm}
% Using the |spacing| environment we can define a new todonote
% command using the code below:
% \begin{verbatim}
% \newcommand{\smalltodo}[2][]
%     {\todo[caption={#2}, #1]
%     {\begin{spacing}{0.5}#2\end{spacing}}}
% \end{verbatim}
% \newcommand{\smalltodo}[2][]
%     {\todo[caption={#2}, #1]
%     {\begin{spacing}{0.5}#2\end{spacing}}}
% Todonotes with decreased line spacing can now be inserted as
% follows
% \smalltodo[size=\footnotesize]{
% Some lines with a decreased line spacing. This is accomplished
% using the setspace package that is included in standard latex
% distributions.}
% \begin{verbatim}
% \smalltodo[size=\footnotesize]{
% Some lines with a decreased line spacing. This is accomplished
% using the setspace package that is included in standard latex
% distributions.}
% \end{verbatim}
%
%
%
% \subsubsection{Comments ''a la Word''}
%
% Fabrice Niessen sent me the following usecase.
% The idea is to define a new command |\mycomment| which adds a
% counter and optionally the initials of the auther to the inserted
% todonote.
% 
% \begin{verbatim}
% \newcounter{mycomment}
% \newcommand{\mycomment}[2][]{%
%    % initials of the author (optional) + note in the margin
%    \refstepcounter{mycomment}%
%    {%
%        \setstretch{0.7}% spacing
%        \todo[color={red!100!green!33},size=\small]{%
%            \textbf{Comment [\uppercase{#1}\themycomment]:}~#2}%
%    }}
% \end{verbatim}
% \newcounter{mycomment}
% \newcommand{\mycomment}[2][]{%
%    \refstepcounter{mycomment}%
%    {%
%        \setstretch{0.7}%
%        \todo[color={red!100!green!33},size=\small]{%
%            \textbf{Comment [\uppercase{#1}\themycomment]:}~#2}%
%    }}
% 
% The command |\mycomment[HSM]{Testing first time.}| is displayed
% \mycomment[HSM]{Testing first time.}%
% like shown in the left margin, and another call of the command is
% added below |\mycomment[HSM]{Testing second time.}|.
% \mycomment[HSM]{Testing second time.}%
%
