+
+	  <para>Longer answer: if you have made any changes using
+	    <command>pkg</command> converting back is non-trivial and
+	    requires lots of manual editing of internal package
+	    database files.  However, if you have just run
+	    <command>pkg2ng</command> then you may remove
+	    <filename>/var/db/pkg/local.sqlite</filename>
+	    and extract
+	    <filename>/var/backups/pkgdb.bak.tbz</filename>.
