+.TH tcl_stat.d 1m "$Date:: 2007-10-03 #$" "USER COMMANDS"
+.SH NAME
+tcl_stat.d - Tcl operation stats using DTrace.
+.SH SYNOPSIS
+.B tcl_stat.d
+[interval [count]]
+.SH DESCRIPTION
+This traces activity from all Tcl processes on the system with DTrace
+provider support (tcl8.4.16).
+
+The numbers are counts for the interval specified. The default interval
+is 1 second.
+
+If you see a count in "EXECS" but not in the other columns, then you
+may have older Tcl software that does not have the integrated DTrace
+provider (or newer software where the provider has changed).
+.SH OS
+Any
+.SH STABILITY
+Evolving - uses the DTrace Tcl provider, which may change
+as additional features are introduced. Check Tcl/Readme
+to see what version these scripts are based on.
+.SH EXAMPLES
+.TP
+Default output,
