<subsection name="Paths">

<p>Consider allowing the user to configure the ant system by setting the
following path types.</p>
<ul>
<li>ant.type.path: path that is used to search for the type libraries</li>
<li>ant.ext.path: path that is used to search for "Optional Packages"
or extensions.</li>
</ul>
<p>
The default search path will probably include a per-user path element,
a workspace path element and a system path elemtn that are searched in
that order. Some possible defaults;
