<h2>NAME</h2>
<p style="margin-left:11%; margin-top: 1em"><b>x_setup</b>
− Determine Pairs of Legs that need Cross-Over
Checking</p>
<a name="SYNOPSIS"></a>
<h2>SYNOPSIS</h2>
<p style="margin-left:11%; margin-top: 1em"><b>x_setup</b>
[ <b>−L</b><i>legfile</i> ] [
<b>−R</b><i>west/east/south/north</i> ]</p>
<a name="DESCRIPTION"></a>
<h2>DESCRIPTION</h2>
<p style="margin-left:11%; margin-top: 1em"><b>x_setup</b>
scans the <i>gmtindex.b</i> file that contains information
on which legs occupy each 1 by 1 degree bin and reports all
the pairs of legs that may overlap. Each pair is only
reported once, even if the two legs involved are found in
other bins also.</p>

<p style="margin-top: 1em" valign="top">Only report pairs
where at least one of the legs are present in the

<h2>BEWARE</h2>
<p style="margin-left:11%; margin-top: 1em">The
<b>−L</b> option is useful when one wants to check out
a handful of new cruises. Obviously we only need to compute
COEs for the pairs that involve one or two of the new
cruises, since all the other combinations have already been
done.</p>
