<h2 id="loadproperties">LoadProperties</h2>
<h3>Description</h3>
<p>Load a file's contents as Apache Ant properties.  This is equivalent to <code>&lt;property
file|resource=<q>...</q>/&gt;</code> except that it supports nested <code>&lt;filterchain&gt;</code>
elements.  Also if the file is missing, the build is halted with an error, rather than a warning
being printed.</p>

<p><strong>Note</strong>: the default value of this task's <var>prefixValues</var> attribute is
different from the default value of the same attribute in
the <a href="property.html"><code>&lt;property&gt;</code></a> task.</p>
