What's the difference between a REST system and a system that is RESTful?

From a few things I've read most so called REST services are actually RESTful services. So what is the difference between the two.

+8  A: 

"REST" is an architectural paradigm. "RESTful" describes using that paradigm.

+9  A: 

Representational state transfer (REST) is a style of software architecture. As described in a dissertation by Roy Fielding, REST is an "architectural style" that basically exploits the existing technology and protocols of the Web.

RESTful is typically used to refer to web services implementing such an architecture.

As Jason said in the comments, RESTful is just used as an adjective describing something that respects the REST constraints.
