%\lstinline{realhats} is a package for \LaTeX{} that makes the \lstinline{\hat} command
%put real hats on symbols.
%For example, the input \lstinline@\hat{a}=\hat{b}@ will produce the output:
%\[\hat{a}=\hat{b}\]
%To make a vector with a hat, the input \lstinline@\hat{\mathbf{a}}@ produces:
%\[\hat{\mathbf{a}}\]
%
%The command \lstinline{\hat} will choose a hat randomly from ten hats:
%\begin{itemize}
%\item \(\hatn{a}{beret}\) - A beret
%\item \(\hatn{a}{santa}\) - A Santa hat
%\item \(\hatn{a}{sombrero}\) - A sombrero
%\item \(\hatn{a}{witch}\) - A witch's hat
%\item \(\hatn{a}{tophat}\) - A top hat
%\item \(\hatn{a}{ash}\) - Ash's hat
%\item \(\hatn{a}{fez}\) - A fez
%\item \(\hatn{a}{cowboy}\) - A cowboy hat
%\item \(\hatn{a}{crown}\) - A crown
%\item \(\hatn{a}{dunce}\) - A dunce's cap
%\end{itemize}
%
%Variables can be given a non-random hat, using the command \lstinline{\hat} with an optional parameter:
%\begin{itemize}
%\item \lstinline@\hat[beret]{a}@ produces \(\hat[beret]{a}\)
%\item \lstinline@\hat[santa]{a}@ produces \(\hat[santa]{a}\)
%\item \lstinline@\hat[sombrero]{a}@ produces \(\hat[sombrero]{a}\)
%\item \lstinline@\hat[witch]{a}@ produces \(\hat[witch]{a}\)
%\item \lstinline@\hat[tophat]{a}@ produces \(\hat[tophat]{a}\)
%\item \lstinline@\hat[ash]{a}@ produces \(\hat[ash]{a}\)
%\item \lstinline@\hat[fez]{a}@ produces \(\hat[fez]{a}\)
%\item \lstinline@\hat[cowboy]{a}@ produces \(\hat[cowboy]{a}\)
%\item \lstinline@\hat[crown]{a}@ produces \(\hat[crown]{a}\)
%\item \lstinline@\hat[dunce]{a}@ produces \(\hat[dunce]{a}\)
%\end{itemize}
%
%You can also pass these same options when loading the package.
%For example, \verb@\usepackage[ash]{realhats}@ will cause the package to use make {\LaTeX} great again hats
%everywhere (unless an different hat is given to the \verb@\hat@ command).
