# numerical identifier for individual Macs based on the Mac's machine UUID.
# This numerical identifier in turn is designed to be used to determine deployment
# groups.

# By default, this script is designed to set up and assign Macs to seven
# deployment groups, with the following percentage of Macs assigned to
# each group.
#
# Group % of Macs
