# Looks through the Day One journal and finds the latest entry that starts with
# the "Entry Start Text" provided on the command line. The script then asks for
# input, reading lines until it comes to one that contains just a single full
# stop "." . The script asks for confirmation and appends a new line followed
# by the entered text to the end of the entry.
#
# NOTE: the user is responsible for creating new entries as necessary,
# presumably once per day.
