# processes a tab-separated "deadlines" file and alerts for any upcoming events.
#
# deadlines.tsv file format:
# - <date>\t<event>
# - <date>\t<reminder-interval>\t<event>
# - no header
# - one line per entry
# - <event> may contain any non-newline and non-tab characters
# - <notice-interval> is the number of days before the event to start alerting, followed by 'd', e.g. `14d`
# - <date> should be lexicographically orderable and machine-parsable, e.g. `2023-03-14`
#
# example `deadlines.tsv`
# 2023-03-14 celebrate pi day!
# 2023-04-18 taxes due
# 2023-04-01 the other pie day :o
# 2023-03-14 1d celebrate pi day!
# 2023-04-18 14d taxes due
# 2023-04-01 7d the other pie day :o
# configurables:
