public class SystemProperties
extends java.util.Properties

A set of property bindings that are initialised from system properties passed on the command line (typically using the "-D" option). All property names are assumed to be in the form basename.suffix where basename is common to all properties. The basename will typically correspond to the name of a class or application. When constructing the class a set of legal suffixes is specified. If a system property is found with the specified but an illegal suffix then an IllegalArgumentExpcetion will be thrown.
