<p>Modes are defined in a <code>builder-mode</code> node which has one attributes,
<code>name</code>, which contains the name of the model, and which supports the
following sub-nodes:
</p>
<dl compact="compact">
<dt><code><description></code></dt>
<dd><p>A one-line description of what the Mode does
</p></dd>
<dt><code><subdir></code></dt>
<dd><p>Optional. The base name of the subdirectory to create for this Mode.
The macro argument <code>%subdir</code> in the <code>extra-args</code> nodes will be
substituted with this.
</p></dd>
<dt><code><supported-model></code></dt>
<dd><p>The name of a model supported by this Mode. There can be multiple
<code>supported-model</code> nodes, each corresponding to a supported Model.
Optionally, you can specify a <code>filter</code> attribute for this node,
corresponding to the switches that are relevant for this mode. By default,
all switches will be taken into account.
The <code>extra-args</code> of the Mode that match <code>filter</code> will be passed
to commands of the supported Models.
</p></dd>
<dt><code><extra-args></code></dt>
<dd><p>Contains a list of <code><arg></code> nodes, each containing one extra argument
to append to the command line when launching Targets while this Mode is
active.
Macros are supported in the <code><arg></code> nodes.
