#If you're overwriting the path and running this script please be sure to BACKUP your original DriverGroups.xml file.
#Please feel free to tweak this script to suit your needs.
#Below there is an exclude group list.  I'd recommend putting your top level folders in this group. (Default and Hidden are already hard coded in)
