 * Utility class to contain version numbers in "Dewey Decimal"
 * syntax.  Numbers in the "Dewey Decimal" syntax consist of positive
 * decimal integers separated by periods ".".  For example, "2.0" or
 * "1.2.3.4.5.6.7".  This allows an extensible number to be used to
 * represent major, minor, micro, etc versions.  The version number
 * must begin with a number.
 *
 * Original Implementation moved to org.apache.tools.ant.util.DeweyDecimal
 * @deprecated use org.apache.tools.ant.util.DeweyDecimal instead.
 * Deprecated since ant 1.8
