\title{Some \LaTeX\ utils}
\author{jlh}

\maketitle

This document demos some things I've collected for nicer texing.
For instance, underlines like this \myuline{example}.

Also, citations with auto links, like this: check out
the link in the refences when I cite, e.g.~\citet[][]{mackay.d:2003,
harremoes.p:2007,schwartz.m:2008,upper.d:1974}.
Links are auto-generated from the \texttt{url}, \texttt{doi}, etc.\ fields.

\begin{kast}{Simple titled box}
  For a box like this, use the \texttt{kast} environment.
\end{kast}

Information theory operators, for things like this:
\begin{align}
  \I{X;Y} &= \KL{P_{(X,Y)}}{P_X \otimes P_Y}
          &&= \E_{p_{(X,Y)}}{\log \frac{p_{(X,Y)}(x,y)}{p_X(x)p_Y(y)}}\\
          &= \H{X} - \H{X\mid Y}\\
          & &&= \int_{\mathcal{X}\times\mathcal{Y}}
          \log \mleft(\frac{\mathrm{d}P_X \otimes
          P_Y}{\mathrm{d}P_{(X,Y)}}\mright) \,\mathrm{d}P_X \otimes P_Y
\end{align}
