29     A quick and dirty class for generating a properties file from the maint
30     property in DBMS.properties and release.properties. Useful for getting
31     the values of the third and fourth parts of the version number into Ant
32     as separate properties. It puts the third value into the output properties
33     as the property "interim", and the fourth value as "point".
