# NOTE: This isn't comprehensive at all. It's mainly meant to be used when 'anvil-file-details' is looking on
#       the hosts for a file it is missing.

# Exit codes;
# 0 = Normal exit or md5sum of this program changed and it exited to reload.
# 1 = '--file <full_path>' not used.
# 2 = File not found.
