    <p>Welcome to the nPULSE web-based network monitoring program for Linux and Unix. 
    If you have already set up nPULSE, then jump right into the <a href="$Compactdisplay_url">Compact</a> or 
    <a href="$Basicdisplay_url">Basic</a> monitoring page.
    For help, check out the <a href="$Help_url">Help Page</a>.</p>
    <p>Otherwise you should manually <a href="npulse.cgi?a=setup&s=edit">Setup</a> 
    nPULSE and click on the 'Recheck' button for a first check of your network. 
    (See the README file for more information.)</p>
    <p>To change the scanning speed of nPULSE, set the timing values in Settings/Timing 
    (especially the ScanDelay value).</p>
    <hr><p><small>This software is a "proof of principle" prototype. The concept is to use
    freely available software (under the GPL agreement) together with
    "glue" software to solve real-world problems. nPULSE accomplishes
    this by using the following freeware products:</small></p>
    <blockquote><table>
    <tr><td><small>PERL</small></td><td><small>Perl 5.004 or greater</small></td></tr>
    <tr><td><small>NMAP</small></td><td><small>Network exploration tool V2.51 or greater</small></td></tr>
    <tr><td><small>TRACEROUTE&nbsp;</small></td><td><small>Packet tracking tool</small></td></tr>
    <tr><td><small>MINISERV</small></td><td><small>Web Server (written entirely in Perl)</small></td></tr>
    <tr><td><small>HTML</small></td><td><small>nPULSE is Web-enabled and Web-driven</small></td></tr>
    <tr><td><small>SH</small></td><td><small>Install scripts are in 'sh' shell script</small></td></tr>
    <tr><td><small>OPENSSL</small></td><td><small>Secure Sockets Layer API</small></td></tr>
    </table></blockquote>
    <p><small>The glue that holds the whole thing together is a set of custom Perl routines
    and a single CGI program.</small></p>
