# This script asks with a GUI dialog how many minutes your kid is allowed to play.
# When time has passed, the script will warn your kid and then shut down.
# You can specify multiple periods if multiple kids want to play; 
# this script will notify when it's time for them to swap places.

# Change log:
# 2016-03-11 - Initial upload (Dutch interface) to Github - Onno Zweers
# 2016-03-13 - Internationalizing - Onno Zweers
