[Pharo-project] How to create/register RPackage/MCPackage packages

Hi guys. So far, when we export/import packages with Fuel, we have our own FLPackage that we serialize/materialize. We get that info from a PackageInfo. Now, my question is, say I have materialized a package, how can I do (by code) to create and register in the system a normal package from our FuelPackage. Any idea? thanks -- Mariano http://marianopeck.wordpress.com
