Generating SQL from the NHibernate mapping file

I spent 10 minutes searching for a simple program that would dump out the SQL that NHibernate generates from a mapping file if requested. In the end I just wrote my own. This is the relevant snippet.

                NHibernate.Cfg.Configuration config = new NHibernate.Cfg.Configuration();

                config.Configure();

                config.AddFile("hbm_mapping.xml");

                var export = new NHibernate.Tool.hbm2ddl.SchemaExport(config);

                export.Execute(true, false, false, true);
