<h1 align=center>Very Trivial Example</h1>
This example is extremely trivial, and thus useful for
investigating problems you might have installing the
extension.
<p>
To build the example, you must first build the
<a href=nsplugin.html>Qt Netscape Plugin Extension</a> library.
Then type <tt>make</tt> in <tt>extensions/nsplugin/examples/trivial/</tt>
and copy the resulting <tt>trivial.so</tt> or <tt>nptrivial.dll</tt>
to the Plugins directory of your WWW browser.
