public class MigrateTopLinkToEclipseLink
Provides a product rename utility specific to moving Oracle TopLink source to EclipseLink.
In addition to invoking the package-rename utility it also clears out the target folder
except the doNotDeleteFiles. When copying and renaming classes the renamer will NOT replace
existing files. This allows us to modify target files and keep the modifications from future
executions overwriting them.
