is there a way to reverse engineer an existing schema into Liquibase?

We have an existing schema created the old fashioned way with raw SQL.  I’d like to reverse engineer it into a nice clean Liquibase change set.  Is there any easy way to do that?

This link shows how to reverse engineer with liquibase.  I have not yet worked through this, so YMMV
