[rules-users] creating .pkg from .drl

[Esteban Aliverti]

Try to add all the packages to a kbuilder and then serialize the resulting
packages. You will need to create a PKG per logical package though. If your
DSLR and DSL files are in the same logical package, the kbuilder will only
contain one package that you have to serialize.


Best,
