.SH DESCRIPTION
syscallbysysc.d is a DTrace OneLiner to a report of the number of 
each type of system call made.

This is useful to identify which system call is the most common.

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.
