<div class="block">A dependency analyzer analyzes dependencies between Java classes to
determine the minimal set of classes which are required by a set of
"root" classes. Different implementations of this interface can
use different strategies and libraries to determine the required set. For
example, some analyzers will use class files while others might use
source files. Analyzer specific configuration is catered for through a
generic configure method</div>
