Far too much used design pattern ;-)
Seriously it is a design pattern that ensures that there is only one
instance of a class.
I don't like the singleton pattern because of this very restriction. It
limits the reusabillity of a class.
Read the "Gang of Four"(Design Patterns, Gamma et al.) book for more
information on singletons and other design patterns.
