-.IP "\fB--appctl-command=\fIcommand\fR"
-Sets the command that \fBovs\-brcompatd\fR runs to communicate with
-\fBovs\-vswitchd\fR. The command is run in \fB/bin/sh\fR as a shell
-command, so \fIcommand\fR may contain arbitrary shell metacharacters,
-etc. The \fB--help\fR option displays the default command.
-.IP
-\fIcommand\fR must contain exactly one instance of \fB%s\fR, which
-\fBovs\-brcompatd\fR replaces by a command from the set understood by
-\fBovs\-vswitchd\fR. Any instances of \fB%%\fR in \fIcommand\fR are
-replaced by a single \fB%\fR. The \fB%\fR character may not otherwise
-appear in \fIcommand\fR.
-.IP
-The commands that are substituted into \fIcommand\fR are those that
-can be listed by passing \fB-e help\fR to \fBovs\-appctl\fR with
-\fBovs\-vswitchd\fR as target. The command that is substituted may
-include white space-separated arguments, so \fIcommand\fR should include
-shell quotes around \fB%s\fR.
-.IP
-\fIcommand\fR must not redirect \fBovs\-appctl\fR's standard output or
-standard error streams, because \fBovs\-brcompatd\fR expects to read
-both of these streams separately.

+Sets the name to the program that \fBovs\-brcompatd\fR runs to
+communicate with \fBovs\-vswitchd\fR. The default is
+\fBovs\-appctl\fR. Unless \fIprogram\fR contains \fB/\fR,
+\fBovs\-brcompatd\fR will search the \fBPATH\fR environment variable
+to find it.
