NAME

       lastwords - print syscalls before exit. Uses DTrace.

SYNOPSIS

       lastwords command

DESCRIPTION

       This  prints  the  last few system calls for processes matching the given name, when they exit. This makes use of a ring buffer so that the
       impact on the system is minimised.
