title: vertical line between latex minipages
body: <p>right now I have a latex section that looks like</p>
  
  <pre><code>\begin{minipage}{0.35\textwidth}   %left column
  ...
  \end{minipage}
  \hfill
  \begin{minipage}{0.55\textwidth} %right column
  ...
  \end{minipage}
  </code></pre>
  
  <p>This makes a nice looking two column layout, but I would like to add a vertical bar between the two minipages (where I currently have \hfill). What is the easiest way to do this?</p>
