<h2>DESCRIPTION</h2>
<p style="margin-left:11%; margin-top: 1em"><b>x2sys_report</b>
will read the input crossover ASCII data base
<i>coedbase.txt</i> (or <i>stdin</i>) and report on the
statistics of crossovers (<i>n, mean, stdev, rms,
weight</i>) for each track. Options are available to let you
exclude tracks and limit the output.</p>
