+.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.
+.IQ "\fBschema\-version\fI schema\fR"
+Prints the version number in the schema embedded within the database
+\fIdb\fR or in the standalone schema \fIschema\fR on stdout. A schema
+version number has the form \fIx\fB.\fIy\fB.\fIz\fR. See
+\fBovs\-vswitchd.conf.db\fR(5) for details.
.IP
Schema version numbers and Open vSwitch version numbers are
independent.
.IP
-If \fIdb\fR was created before schema versioning was introduced, then
-it will not have a version number and this command will print a blank
-line.
+If \fIschema\fR or \fIdb\fR was created before schema versioning was
+introduced, then it will not have a version number and this command
+will print a blank line.
.
-.IP "\fBschema\-version\fI schema\fR"
-Reads \fIschema\fR and prints the schema's version number on stdout.
+.IP "\fBdb\-cksum\fI db\fR"
+.IQ "\fBschema\-cksum\fI schema\fR"
+Prints the checksum in the schema embedded within the database
+\fIdb\fR or of the standalone schema \fIschema\fR on stdout.
.IP
-If \fIschema\fR was created before versioning was introduced, then it
-does not have a version number and this command will print a blank

+introduced, then it will not have a checksum and this command

.IP "\fBquery\fI db transaction\fR"
Opens \fIdb\fR, executes \fItransaction\fR on it, and prints the
\fBovsdb\-server\fR(1).
.
.IP "\fBshow\-log\fI db\fR"
-Prints a summary of the records in \fBdb\fR's log, including the time
+Prints a summary of the records in \fIdb\fR's log, including the time
and date at which each database change occurred and any associated
comment. This may be useful for debugging.
