[rules-dev] Convert .brl to .drl

I have found this: ....you can use the following snippet of code to convert the brl to a drl rule: BRXMLPersitence read = BRXMLPersitence.getInstance(); BRDRLPersistence write = BRDRLPersistence.getInstance(); String brl = ... read from the .brl file as needed... String outputDRL = write.marshall(read.unmarshal(brl)); //then pass the outputDRL to the PackageBuilder as normal Can you explain please: "String brl = ... read from the .brl file as needed..." for example if I have "first.brl" and I want "first.drl" Thank you...
