Yes I do have the correct version of the manual. Here is the file name:
drools-distribution-6.0.0.Final/reference_manual/html/ch06.html#d0e3594
or on the net:
http://docs.jboss.org/drools/release/6.0.1.Final/drools-docs/html/ch06.ht...
As you can see it references the .rf style. Also the way that it is laid out has rule
flow groups. The idea is that name corresponds to the rule flow group noted in the Rule
file (drl). In the Drools 6.0 plugin, there is no rule-flow icon, only start event, end
event, rule task, etc.
