#     Description:  This script is an Extension Attribute (EA) for the Casper Suite/Jamf Pro
#                   Server. It checks com.apple.commerce.plist for the associated Apple ID
#                   and prints it out for display on the computer record in the JSS.
#            Note:  This is a replacement for com.apple.storeagent.plist which no longer
#                   exists on Sierra (10.12.x).
