Initial import of p5-Class-Singleton, version 1.03, into the NetBSD
Packages Collection.

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.
