# https://github.com/hossman/ifttt-trigger
#
# uses the ifttt Maker channel to trigger an event with some optional input
#   https://ifttt.com/maker
#
# If the HTTP request to fire the ifttt event fails for any reason, the original event input will be 
# written to STDOUT, and the script will die with the details of the HTTP error.
#
# this should (in theory) allow you to chain this script with something else as a fall back (ie: notify-send)
# so you can still get *some* notification, while also accessing the full details of the error.
