+.TH hotspot.d 1m  "$Date:: 2007-08-05 #$" "USER COMMANDS"
+.SH NAME
+hotspot.d \- print disk event by location. Uses DTrace.
+.SH SYNOPSIS
+.B hotspot.d
+.SH DESCRIPTION
+hotspot.d is a simple DTrace script to determine if disk activity is 
+occuring in the one place - a "hotspot". This helps us understand the 
+system's usage of a disk, it does not imply that the existance or not 
+of a hotspot is good or bad (often may be good, less seeking).
+
+Since this uses DTrace, only the root user or users with the
+dtrace_kernel privilege can run this command.
+.SH OS
+Solaris
+.SH STABILITY
+stable - needs the io provider.
+.SH EXAMPLES
+.TP
+Sample until Ctrl\-C is hit then print report,
