Subject: best practices for exception hierarchies?

What are best-practices for exception hierarchies?

Should my exceptions derive from Exception, or StandardError, or  
RuntimeError?

Should my exceptions be called FooException or FooError?  Does Ruby  
give a specific meaning to the difference between an "Error" and an  
"Exception?"
