				<p>Epsilon provides a set of ANT tasks (<a href="http://ant.apache.org">what is ANT?</a>) to enable developers to assemble complex workflows (build scripts) that involve both MDE (e.g. transformation, validation) and non-MDE (e.g. copying files, invoking compilers) tasks. Epsilon tasks are underpined by a communication mechanism that enables them to interact with each other by sharing models and variables.</p>

		<h3>Features</h3>
		<div class="row">
			<div class="span8">
				<ul>
					<li>Call Epsilon programs from ANT
					<li>Models are loaded once and tasks share them
					<li>Tasks can communicate by exporting/importing variables at runtime
					<li>Dedicated task for loading EMF models
					<li>Dedicated task for loading registered EMF EPackages
					<li>Can specify Epsilon code directly inside the tags of the task
				</ul>
