perl-Class-Singleton

This is the "Class::Singleton" module. A Singleton describes an object class that can have only one instance in any system. An example of a Singleton might be a print spooler or system registry. This module implements a Singleton class from which other classes can be derived. By itself, the "Class::Singleton" module does very little other than manage the instantiation of a single object. In deriving a class from "Class::Singleton", your module will inherit the Singleton instantiation method and can implement whatever specific functionality is required.
