Latest Iteration Of Timer Script
Published on 30 December, 2015 by amj* Updated on 18 October, 2022 by amj
This script calls an external tk file which is linked to at the bottom of the page only because I haven't figured out how to run the python code within the script.

# This is a rewrite of a script that
# originally ran for a preset length
# of time. It now runs for an arbitrary
# number de Minutos.
