+.TH priclass.d 1m  "$Date:: 2007-08-05 #$" "USER COMMANDS"
+.SH NAME
+priclass.d \- priority distribution by scheduling class. Uses DTrace.
+.SH SYNOPSIS
+.B priclass.d
+.SH DESCRIPTION
+This is a simple DTrace script that samples at 1000 Hz the current
+thread's scheduling class and priority. A distribution plot is printed.
+
+With priorities, the higher the priority the better chance the thread
+has of being scheduled.
+
+This idea came from the script /usr/demo/dtrace/pri.d, which
+produces similar output for priority changes, not samples.
+
+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.
+.SH EXAMPLES
+.TP
+This samples until Ctrl\-C is hit.
