+\fImodule\fR may be any valid module name (as displayed by the
+\fB--list\fR action on \fBvlogconf\fR(8)), or the special name
+\fBANY\fR to set the logging levels for all modules.

+.IP \(bu
+\fIfacility\fR may be \fBsyslog\fR, \fBconsole\fR, or \fBfile\fR to

+respectively, or \fBANY\fR to set the logging levels for both
+facilities. If it is omitted, \fIfacility\fR defaults to \fBANY\fR.

+.IP \(bu
+\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

+\fB--log-file\fR[\fB=\fIfile\fR]
+Enables logging to a file. If \fIfile\fR is specified, then it is

+used if \fIfile\fR is omitted is @LOGDIR@/\fIprogram\fR.log, where
+\fIprogram\fR is the name of the program as invoked
+(e.g. \fBsecchan\fR).
