+ SystemTap uses a different notation for trace scripts than DTrace does,

+ even though the underlying trace points are compatible. One point worth

+ noting is that at this writing, SystemTap scripts must reference probe

+ names using double underlines in place of hyphens. This is expected to

+ be fixed in future SystemTap releases.

You should remember that DTrace scripts need to be carefully written and

debugged, otherwise the trace information collected might

discussing information found using dynamic tracing, be sure to enclose

the script used to allow that too to be checked and discussed.
