#!/usr/bin/env sh
# This script prints in reverse chronological order unique entries from the
# modem log merged with contact names defined in contacts file tsv.
#   Wherein $CONTACTSFILE is tsv with two fields: number\tcontact name
#   Wherein $LOGFILE is *sorted* tsv with three fields: date\tevt\tnumber
#
#   Most normal numbers should be a full phone number starting with + and the country number
#   Some special numbers (ie. 2222, "CR AGRICOLE") can ignore this pattern
#
# Prints in output format: "number: contact"
