<h2>DESCRIPTION</h2>
<p style="margin-left:11%; margin-top: 1em"><b>psmeca</b>
reads data values from <i>files</i> [or standard input] and
generates <i>PostScript</i> code that will plot focal
mechanisms on a map. Most options are the same as for
<b><A HREF="psxy.html">psxy</A></b>. The <i>PostScript</i> code is written to
standard output.</p>
