exporting package definitions with vlt
We're trying to export as much configuration info to our source control system as we can. Generally we use vlt to export the appropriate crx nodes. However, we are stuck on packages. As far as I can tell, the package definitions are stored under /etc/packages/group/package.zip/jcr:content/vlt:definition. The problem is that the built package itself is "package.zip", which we don't want to export and put in source control, just the definition (name, description, filters, etc); and vlt doesn't seem to want to exclude a directory but include children of that directory.
How can we export the package definition but not the actual package?
