+\begin{abstract}
+ Pretty-print token lists.
+\end{abstract}
+
+\section{Usage}
+
+\subsection{Main function}
+\begin{function}{\pretty:n,\pretty:x,\pretty:o,\pretty:V}
+ \begin{syntax}
+ \cs{pretty:n} \Arg{token list} \\
+ \end{syntax}
+ Print the content of \meta{token list}.
+\end{function}
+
+\begin{function}{\pretty:N,\pretty:c}
+ \begin{syntax}
+ \cs{pretty:N} \meta{token} \\
+ \cs{pretty:c} \Arg{control sequence name} \\
+ \end{syntax}
+ Print \meta{token}. \\
+ This function is not very useful. Usually it's preferable to use |\pretty:V| to print a token list variable's value,
+ or |\prettyshow:N| to print a control sequence's meaning.
+\end{function}
+
+\subsection{View result}
+
+The result is printed to a HTML file named |pretty-|\meta{jobname}|.html| by default.
+Open the file in any browser to view the result.
+
+Note that the HTML file will not be touched if nothing is printed, as such it's encouraged to add a line such as |\pretty:n {start}| right after loading the file.
+
+Why HTML file?
+
+\begin{itemize}
+ \item Because if the TeX program stops with error / has some error that corrupts the PDF output, the output will even with corrupted more by the debug print.
+ \item Printing to the console is extremely limited (difficult syntax highlighting/scrolling/line wrapping), and most likely cluttered with the traceback/other TeX default output.
+ \item Output to another \TeX\ file to be compiled is a bit absurd, and compiling \TeX\ file takes longer than loading a HTML file.
+\end{itemize}
+
+By default, the output refreshes whenever the TeX file is recompiled. The behavior
+can be customized with \cs{prettyrefreshstrategy} and \cs{prettyrefreshduration}.
+
+\subsection{\LaTeX2 interface}
+
+
+\begin{function}{\prettyN,\prettyX,\prettyO,\prettyV}
+ \begin{syntax}
+ \cs{prettyN} \Arg{token list} \\
+ \end{syntax}
+ Alias of the correspondingly-named commands.
+\end{function}
+
+\subsection{Additional functions}
+
+There are also these functions, for convenience.
+
+\begin{function}{\pretty:nn, \pretty:nnn}
+ \begin{syntax}
+ \cs{pretty:nn} \Arg{token list} \Arg{token list}
+ \cs{pretty:nnn} \Arg{token list} \Arg{token list} \Arg{token list}
+ \end{syntax}
+ Print multiple token lists.
+\end{function}
+
+\begin{function}{\pretty:w}
+ \begin{syntax}
+ \cs{pretty:w} \meta{token list} \cs{prettystop}
+ \end{syntax}
+ Print the content of \meta{token list}. For now, it must be brace-balanced.
+\end{function}
+
+\begin{function}{\prettyshow:N}
+ \begin{syntax}
+ \cs{prettyshow:N} \meta{token}
+ \end{syntax}
+ Show the meaning of a |N|-type argument.
+\end{function}
+
+\subsection{Customization}
+
+These variables can be redefined before the
+first call to |\pretty:n| to customize the behavior.
+
+\begin{variable}{\prettyfilename}
+ The output file name. Defaults to |pretty-|\meta{jobname}|.html|, as mentioned above.
+\end{variable}
+
+\begin{variable}{\prettyrefreshstrategy}
+ The auto-refresh strategy. Allowed values are 0-4. 0 is no refresh. \\
+ Which value works best depends on the particular browser. \\
+ On Google Chrome, passing |--allow-file-access-from-files| may be useful.
+\end{variable}
+
+\begin{variable}{\prettyrefreshduration}
+ The duration between two consecutive refresh check, in milliseconds. Defaults to 1000.
+\end{variable}
+
+\begin{variable}{\prettypreamble}
+ The HTML source code preamble. This can be redefined to change styles, but the
+ behavior is not guaranteed.
+\end{variable}
+
+\section{Implementation}
+
+Unfortunately, the implementation is not typesetted in \TeX. Read the |.sty| file.
