\section{Introduction}

\label{INTRO}

One of the oldest problems in Latex is how to maintain
compatibility between the latex that is used `in the wild'
and the latex that is used by Wysiwig editors like Lyx.

See Fig (\ref{yfig}) for a comparison that
shows growth in the statistical variance 
of files after multiple
import/export, as a function of time in years,
using several different sample files.
