How to use the parrun package

Question

The documentation for the parrun package claims it can be used to display parallel text. I cannot find any example code showing how to use it and I have failed to create a simple example to test how it work. How do I get this package to display parallel text as it was designed to?

Answer 1

You place one text stream in the fframe (f for "first" perhaps) environment, the other in the sframe (s for "second"?) environment, and add a \Place or \Place* command to typeset the contents of the environments, one above the other.

\documentclass{article}
\usepackage{parrun}
\usepackage{lipsum}
\usepackage{xcolor}

\begin{document}
\begin{fframe}
\lipsum[1-2]
\end{fframe}
\begin{sframe}
\color{blue}\lipsum[3-4]
\end{sframe}
\Place*
\end{document}
