+.IP "\fBneeds\-conversion\fI db schema\fR"
+Reads the schema embedded in \fIdb\fR and the standalone schema in
+\fIschema\fR and compares them. If the schemas are the same, prints
+\fBno\fR on stdout; if they differ, print \fByes\fR.

.IP "\fBdb\-version\fI db\fR"
-Reads \fIdb\fR and prints the version number of the schema embedded
-within the database on stdout. A schema version number has the form
-\fIx\fB.\fIy\fB.\fIz\fR. See \fBovs\-vswitchd.conf.db\fR(5) for
-details.
