 .TP
+\fB-d|--debug=debuglevel\fR
+\fIdebuglevel\fR is an integer 
+from 0 to 10.  The default value if this parameter is 
+not specified is zero.
+
+The higher this value, the more detail will be 
+logged to the log files about the activities of the 
+server. At level 0, only critical errors and serious 
+warnings will be logged. Level 1 is a reasonable level for
+day to day running - it generates a small amount of 
+information about operations carried out.
+
+Levels above 1 will generate considerable 
+amounts of log data, and should only be used when 
+investigating a problem. Levels above 3 are designed for 
+use only by developers and generate HUGE amounts of log
+data, most of which is extremely cryptic.
+
+Note that specifying this parameter here will 
+override the log
+level file.
+.TP
+\fB-h|--help\fR
+Print a summary of command line options.
+.TP
 \fB-l|--logfile=logbasename\fR
 File name for log/debug files. The extension
 \&'.client' will be appended. The log file is never removed
