# Nothing graphical: it copies, converts and renders files. It is a user
# service rather than a system one because the downloads it watches and
# the library it fills both belong to the classroom account, and a root
# service writing into a teacher's home would have to be told about every
# one of those permissions.

# It exits 0 immediately on a device with PRESENTATIONS_ENABLED=false, and
# on-failure means such a device is left alone rather than restarted in a
# loop forever. A device that does have Presentations gets the watcher
# back if it ever dies, because a teacher whose download never appears has
# no way at all to find out why.
