Several utility classes in Doxia are few used or unused. org.apache.maven.doxia.util.StringUtil (used only in XmlWriterXdocSink, which is not maintained) org.apache.maven.doxia.util.FileUtil (used only in DocBookSink) org.apache.maven.doxia.util.WrappedException (unused). This is just duplicated code and it's hard to maintain, and we have equivalents in Plexus Utils.
I propose to remove them and to use Plexus-utils instead of. It would be a part of DOXIA-56.
Also, I propose to rename the following package org.apache.maven.doxia.site.module.manager to org.apache.maven.doxia.module.site.manager
