# Purpose : Describe this CoreDesktop machine as text, so two machines can be
#           compared with diff (see README.md). Runs in the smoketest VM.
#
# Only what CoreDesktop decides goes in: names, not versions, and no times, so
# a fresh install and an updated older install of the same commit match.
