+.TH syscallbyproc.d 1m  "$Date:: 2007-08-05 #$" "USER COMMANDS"
+.SH NAME
+syscallbyproc.d \- syscalls by process name. Uses DTrace.
+.SH SYNOPSIS
+.B syscallbyproc.d
+.SH DESCRIPTION
+syscallbyproc.d is a DTrace OneLiner to a report of the number of 
+system calls made by process name. 
+
+This is useful to identify which process is causing the most 
+system calls.
+
+Docs/oneliners.txt and Docs/Examples/oneliners_examples.txt
+in the DTraceToolkit contain this as a oneliner that can be cut-n-paste
+to run.
+
+Since this uses DTrace, only the root user or users with the
+dtrace_kernel privilege can run this command.
+.SH OS
+Any
+.SH STABILITY
+stable - needs the syscall provider.
+.SH EXAMPLES
+.TP
+This samples until Ctrl\-C is hit.

+second field
+This is the count, the number of system calls made.
+.PP
+.SH DOCUMENTATION
+See the DTraceToolkit for further documentation under the 
+Docs directory. The DTraceToolkit docs may include full worked
