public class DeweyDecimal extends java.lang.Object implements java.lang.Comparable<DeweyDecimal>
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.
