# Notifies when mail arrives: one notification per account per batch, naming
# the newest senders and subjects.
#
# Watches the notmuch Xapian directory and, on each commit, asks notmuch what
# changed since the revision it last saw. A commit is NOT the same as new
# mail, since reading and tagging also commit, which is why the revision
# counter does the work rather than a count delta.
#
# This is its own process rather than part of waybar-mail.sh, which already
# has the same arrival edge: waybar owns that process, so a bar restart would
# stop notifications with nothing reporting it.
#
# Usage:
#   mail-notify.sh          watch forever (what autostart runs)
#   mail-notify.sh --once   process one tick and exit (what the test drives)
