%\maketitle

%\begin{abstract}
%  The \pkg{zebra-goodies} package defines a collection of handy macros for
%  notes taking during document writing. It is designed to be very simple and
%  good enough for writing common documents independently or collaboratively.
%  Several commands, \cs{todo}, \cs{comment}, \cs{note}, \cs{fixed} and
%  \cs{placeholder}, are provided for quick start. It is also possible to add
%  new notes taking commands with \cs{zebranewnote}.
%\end{abstract}
%
%\tableofcontents
%
%\begin{documentation}
%
%\section{Introduction}
%
% There are quite a few note taking and todo packages available. However, I do
% not like the interfaces they provided. Some of them create a huge, complex
% and complicated feature set trying to fit all use cases, while others abuse
% the margin par to show too many colorful boxes and long text, even worse, some
% packages link the annotations and the original text with arrows, which results
% in a really unreadable document.
%
% So, I need a simple and good enough note taking package. With ``simple'', I
% want the commands to be intuitive and equipped with just necessary arguments.
% With ``good enough'', the document's appearance could be changed a bit to
% present the notes for easy reading but not too much. Additionally, all notes
% should be addressed once the file is in final state. As a kind reminder, a
% summary table presents the notes statistics according to note types at the end
% of the document.
%
% With these objectives in mind, \pkg{zebra-goodies} is created and improved
% along with my writing activities. Apparently, this package is designed with a
% heavy personal bias. It is not supposed to be general and perfect.
%
%\section{Installation}
%
%\changes{v0.7.0}{2019/07/01}{Move to docstrip}
%
% The package is supplied in \file{dtx} format and as a pre-extracted zip file.
% The later is most convenient for most users: simply unzip this in your local
% texmf directory and run \texttt{texhash} to update the database of file
% locations, or just unzip the files into your working directory. If you want to
% unpack the \file{dtx} yourself, running \texttt{tex \jobname.dtx} will extract
% the package whereas \texttt{latex \jobname.dtx} will extract it and also
% typeset the documentation.\footnote{Actually, \texttt{latexmk \jobname.dtx} is
% much better.}
%
%\section{Using the package}
%
% The package should be loaded as normal in the preamble. The package
% recognises a number of options, which can also be used in the document
% body. These are described later in this document.
%\begin{LaTeXdemo}[code only]
%  \usepackage[<options>]{zebra-goodies}
%\end{LaTeXdemo}
%
%\subsection{Notes Macros}
%\begin{function}{\todo}
%  \begin{syntax}
%    \cs{todo}\oarg{name}\marg{note content}
%  \end{syntax}
%\end{function}
%
%  The basic function provided by \pkg{zebra-goodies} is the \cs{todo} macro.
%  This is used to insert a piece of \texttt{todo} note right here, taking a
%  mandatory argument, the \meta{note content} of the \texttt{todo}, and an
%  optional argument, the \meta{name} who should be responsible for this note.
%  For example, the author wants \meta{name} to address this todo. This is very
%  helpful during collaboration. The todo note will be typesetted in a
%  predefined color and quoted in the current paragraph along with the famous
%  symbol in margin par.
%
% \begin{LaTeXdemo}
%   A very simple example of a todo note \todo{how should we go to the lake?},
%   and the result will be presented right below the code snippet. Please
%   compare the code and the result.
% \end{LaTeXdemo}
%
% And, the following example shows how to set the assignees:
%
% \begin{LaTeXdemo}
%   Another one with an assignee is like \todo[tom]{you should buy the ticket},
%   and you will find the same type of notes are numbered. And the assignees are
%   being \texttt{@}-ed right before the text. And another one with many
%   assignees \todo[lucy,jessie]{prepare the foo}.
% \end{LaTeXdemo}

%  Since \pkg{zebra-goodies} uses running texts, so \cs{todo} also works in
%  title macros like \cs{section} and \cs{caption}.
%
%  \begin{LaTeXdemo}[code only]
%    \section{Introduction\todo[jerry]{please figure out a better name}}
%    \begin{figure}
%      \centering
%      \caption{Speed vs distance. \todo[need to insert the figure]}
%    \end{figure}
%  \end{LaTeXdemo}
%
%\begin{function}{\note}
%  \begin{syntax}
%    \cs{note}\oarg{name}\marg{note text}
%  \end{syntax}
%\end{function}
%\begin{function}{\comment}
%  \begin{syntax}
%    \cs{comment}\oarg{name}\marg{comment text}
%  \end{syntax}
%\end{function}
%\begin{function}{\fixed}
%  \begin{syntax}
%    \cs{fixed}\oarg{name}\marg{fixed text}
%  \end{syntax}
%\end{function}
%\begin{function}{\placeholder}
%  \begin{syntax}
%    \cs{placeholder}\oarg{name}\marg{placeholder text}
%  \end{syntax}
%\end{function}
%  All these commands share the same syntax as \cs{todo}, so do the behaviour.
%  They are defined just for convenience for different cases. Nothing magic are
%  behind.
%
%  If any of them does not work, it is very likely that they are defined by
%  other packages. In order to avoid unnecessary confusion, \cs{zebra-goodies}
%  will not \cs{renewcommand} them in case they are defined. So, it comes to
%  their internal counterparts.
%  \begin{LaTeXdemo}
%    A very simple example of a todo note \note{how should we go to the lake?}
%    and another one with an assignee is like \zebracomment[tom]{you should buy
%    the ticket}. As you noticed, \cs{zebracomment} is used instead of \cs{comment}
%    here is because \cs{comment} has been defined by \pkg{l3doc}. Let's move on
%    to other macros. and another one with many assignees
%    \placeholder[lucy,jessie]{prepare the foo} and the issue has been
%    \fixed[John]{good job!}. We'd like to add more lines to separate the bend
%    symbols. Finally, let's try to use the full version like this, I am going
%    to add a \todo{a new todo} and a extended note to be put in another line
%    with useless words as you known like this, this and that and eventually we
%    come to the \note[who]{note}.
%  \end{LaTeXdemo}
%
%  With these macros, it is very simple to good enough for note taking.
%
%\begin{function}{\zebratodo}
%  \begin{syntax}
%    \cs{zebratodo}\oarg{name}\marg{note text}
%  \end{syntax}
%
%  \cs{todo} will not be defined if it has been defined by other packages,
%  please use its internal alias, \cs{zebratodo}. This is how the other notes
%  macros are defined.
%\end{function}
%\begin{function}{\zebranote}
%  \begin{syntax}
%    \cs{zebranote}\oarg{name}\marg{note text}
%  \end{syntax}
%\end{function}
%\begin{function}{\zebracomment}
%  \begin{syntax}
%    \cs{zebracomment}\oarg{name}\marg{comment text}
%  \end{syntax}
%\end{function}
%\begin{function}{\zebrafixed}
%  \begin{syntax}
%    \cs{zebrafixed}\oarg{name}\marg{fixed text}
%  \end{syntax}
%\end{function}
%\begin{function}{\zebraplaceholder}
%  \begin{syntax}
%    \cs{zebraplaceholder}\oarg{name}\marg{placeholder text}
%  \end{syntax}
%\end{function}
%
%\begin{function}{\zebranewnote}
%  \begin{syntax}
%    \cs{zebranewnote}\marg{note name}\marg{xcolor name}
%  \end{syntax}
%  You will eventually need a new note type for whatever reasons.
%  \cs{zebranewnote} needs two arguments to create a new note type. \meta{note
%  name} will be used as the note's macro as \cs{todo}, while the \meta{xcolor_name}
%  defines in what color the new note show be, which should be a \texttt{name} instead
%  of \pkg{xcolor} spec. So, it is necessary to define the color with \cs{definecolor}
%  or \cs{colorlet} in advance as in the following example.
%  \changes{v0.8.0}{2019/07/04}{Fix new note demo}
%  \changes{v0.8.1}{2019/07/04}{Fix doc}
%  \begin{LaTeXdemo}
%    \colorlet{mycyan}{cyan}
%    \zebranewnote{question}{mycyan}
%    When it moves to the next step, we should be fine. \question[who]{what's this?}
%  \end{LaTeXdemo}
%\end{function}
%
%\subsection{Package Options}
%
%\DescribeOption{draft}
%\DescribeOption{final}

% These two options are complementary to each other. When no explicit mode is
% given, \opt{draft} is \texttt{true}, in which case all notes will be
% typesetted as well as the the summary table at end of the document. By setting
% \opt{draft} to \texttt{false} or \opt{final}, notes will not be presented.
%
%\DescribeOption{microtype}
% Enable the great \pkg{microtype} package or not. Default: \texttt{true}. I
% personally love this package very much.
%
%\section{Predefined Colors}
%
% This is for personal use. I often use \pkg{pgfplots} to create plots, however,
% I do not like the default color. So several are define:
% \begin{itemize}
% \item \texttt{zebrablue}
% \item \texttt{zebrared}
% \item \texttt{zebrayellow}
% \item \texttt{zebrapurple}
% \item \texttt{zebragreen}
