/**
 * ScanTargetPattern
 *
 * Utility class to provide the ability for the mvn jetty:run
 * mojo to be able to specify filesets of extra files to
 * regularly scan for changes in order to redeploy the webapp.
 *
 * For example:
 *
 * <scanTargetPattern>
 * <directory>/some/place</directory>
 * <includes>
 * <include>some ant pattern here </include>
 * <include>some ant pattern here </include>
 * </includes>
 * <excludes>
 * <exclude>some ant pattern here </exclude>
 * <exclude>some ant pattern here </exclude>
 * </excludes>
 * </scanTargetPattern>
