[rules-users] Setting Globals inside Rules

Hi all, I have common code that can run a number of different rule base(s) and so far each of the different rule bases have utilized common Global variables (lists of regular expressions and runtime options) However a new rule base will require additional /different globals to be set and i do not want to change the code that invokes the engine and compiles the rule base. Is it possible, by way of an example, to have a rule execute upon rule base initialization and populate a series of global variables? Ideally this would come from a settings config file in the same directory as the rule .drl files. Thanks Gary
