# EXAMPLE for PowerEvents PowerShell module available on http://powerevents.codeplex.com
# Author: Trevor Sullivan
# Date: 11/28/10
# Brief: This example shows how to use PowerEvents to create a WMI event filter that detects the deletion of a computer object in Active Directory (AD).
# Take note that, if a computer account is moved, the WMI instance that represents the computer will be deleted and a new one created. A modification event (__InstanceModificationEvent) will NOT be fired in this scenario.
# Note: This is not a complete working sample of the PowerEvents module. This only shows how to create an event filter.
# A fully functioning sample requires an event consumer, to respond to the events, as well as a binding between the filter and consumer.
