I'm starting to use the maven-011n-package-plugin, as found in the vCO Appliance's onboard Maven Repo or as obtained via the vCO Client's --> Package --> Expand to Folder functionality. First of all, this is a very useful tool, however, the docs are very minimal. And I have couple of questions 
1) Is it REQUIRED that when I build a package ( from the native XML ) I digitally sign it?
2) Is there a library version of the functionality embedded in this Maven plugin? Or can I get the source? Just wondering whether I can do this without getting maven involved; we use gradle.
