+=head1 USE'ING THE MODULE
+
+If you are using this module for the purposes of parsing perf data, you
+will probably want to set use_die => 1 at use time. This forces
+&Nagios::Plugin::Functions::nagios_exit to call die() - rather than exit() -
+when an error occurs. This is then trappable by an eval. If you don't set use_die,
+then an error in these modules will cause your script to exit
