# $Id$ PortSystem 1.0 PortGroup perl5 1.0 perl5.setup Class-Singleton 1.03 maintainers mat@FreeBSD.org description Implementation of a "Singleton" class long_description \ 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. platforms darwin checksums md5 80202a57411cb3e939fec327a87564bf
