org.codehaus.plexus.interpolation.RegexBasedInterpolator
Expansion of the original RegexBasedInterpolator, found in plexus-utils, this interpolator provides options for setting custom prefix/suffix regex parts, and includes a {@link RecursionInterceptor} parameter in its interpolate(..)call, to allow the detection of cyclical expression references. @version $Id$
