%\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 six hats:
%\begin{itemize}
%\item \(\hatn{a}{0}\) - A beret
%\item \(\hatn{a}{1}\) - A Santa hat
%\item \(\hatn{a}{2}\) - A Scottish hat
%\item \(\hatn{a}{3}\) - A sombrero
%\item \(\hatn{a}{4}\) - A wizard's hat
%\item \(\hatn{a}{5}\) - A top hat
%\item \(\hatn{a}{6}\) - A make {\LaTeX} great again hat
%\item \(\hatn{a}{7}\) - A fez
%\item \(\hatn{a}{8}\) - A cowboy hat
%\item \(\hatn{a}{9}\) - A crown
%\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[scottish]{a}@ produces \(\hat[scottish]{a}\)
%\item \lstinline@\hat[sombrero]{a}@ produces \(\hat[sombrero]{a}\)
%\item \lstinline@\hat[wizard]{a}@ produces \(\hat[wizard]{a}\)
%\item \lstinline@\hat[tophat]{a}@ produces \(\hat[tophat]{a}\)
%\item \lstinline@\hat[mlga]{a}@ produces \(\hat[mlga]{a}\)
%\item \lstinline@\hat[fez]{a}@ produces \(\hat[fez]{a}\)
%\item \lstinline@\hat[cowboy]{a}@ produces \(\hat[cowboy]{a}\)
%\item \lstinline@\hat[crown]{a}@ produces \(\hat[crown]{a}\)
%\end{itemize}
%
%You can also pass these same options when loading the package.
%For example, \verb@\usepackage[mlga]{realhats}@ will cause the package to use make {\LaTeX} great again hats
%everywhere (unless an different hat is given to the \verb@\hat@ command).
