 .SH DESCRIPTION
 The \fBvlogconf\fR program configures the logging system used by the 
 OpenFlow userspace programs.  The logging configuration may be modified 
 while OpenFlow programs are running.
 
-\fIMODULE\fR \- The module for which the logging level is being
-modified.  To see a list of supported modules, rerun \fBvlogconf\fR with
-the \fI\-print\fR option.
+\fBvlogconf\fR applies one or more actions to each of one or more
+target processes.  Targets may be specified as:
 
-\fIFACILITY\fR \- The method of logging.  Valid values are \fBSYSLOG\fR and
-\fBCONSOLE\fR.
+.TP
+\fB-a\fR, \fB--all\fR
+All running processes that \fBvlogconf\fR can control.
 
-\fILEVEL\fR \- The level with which the module should be logged.  Valid 
-values are \fBDBG\fR (debug), \fBWARN\fR (warning), \fBERR\fR (error), 
-and \fBEMER\fR (emergency).
+.TP
+\fB-t \fIPID\fR, \fB--target=\fIPID\fR
+The process with the specified \fIPID\fR.  \fIPID\fR may also specify
+an absolute path (beginning with `/') to the Unix domain socket for a
+\fBvlogconf\fR-controllable process.
+
+.PP
+The available actions are:
+
+.TP
+\fB-l\fR, \fB--list\fR
+Print the list of known modules and their current logging levels to
+stdout.
+
+.TP
+\fB-s\fR \fIMODULE\fB:\fIFACILITY\fB:\fILEVEL\fR, \fB--set=\fIMODULE\fB:\fIFACILITY\fB:\fILEVEL\fR
+
+Sets the logging level for \fIMODULE\fR in \fIFACILITY\fR to
+\fILEVEL\fR.  \fIMODULE\fR may be any valid module name (as displayed
+by the \fB--list\fR option) or the special name \fBANY\fR to set all
+modules logging level.  \fIFACILITY\fR may be \fBsyslog\fR or
+\fBconsole\fR to set the levels for logging to the system log or to
+the console, respectively, or \fBANY\fR to set the logging levels for
+both modules.  \fILEVEL\fR must be one of \fBemer\fR, \fBerr\fR,
+\fBwarn\fR, or \fBdbg\fR, designating the minimum severity of a
+message for it to be logged.
