# (optionally) Notify about backup summary stats.
#
# How to perform the notification is up to the user; the script only writes the info to a user-owned file in a fire
# and forget fashion. One option is using a special FIFO file (aka pipe file) on user-side (which will work as a queue)
# together with an auto-started user process to read from that queue and trigger the notification.
#
# Examples of such setup:
# - Linux autostart + cross-platform notifier
# https://github.com/gerardbosch/dotfiles-linux/blob/ea0f75bfd7a356945544ecaa42a2fc35c9fab3a1/home/.config/autostart/notification-queue.desktop
