[rules-users] conversion of .pkg file to other formats

Greetings. I'm using Drools for a project at work. I'm investigating the feasibility of using the BRMS in our environment. I have a question about the binary packages that are available for download from the BRMS. Given one of these .pkg files, is there an easy API call that would get me a text string representing the .drl file equivalent of the .pkg file? I realize that I can use the 'Show package source' from the BRMS. However, if we decide to go with .pkg files for deployment, it would be really nice to be able to get a human-readable form of what was last deployed to production for any given .pkg for auditing / troubleshooting purposes. I perused the docs, and I found something similar to what I want, but it seems to be specific to decision tables. Thanks, Rick
