[rules-users] Rules-Flow question

I am confused as to how to fire off a rules flow (DRL) file. In a stateless session, how many individual rules-flows are valid, how do we choose which one to fire or do they all fire? In a state-full session, I imagine any number of rules-flows would be valid. Is this correct? How do I choose to fire one rules flow, and what happens when I execute a fireAllRules? Do all rules-flow also fire, or none of them? -- Carlos M. De Matos cmdematos.com
