# Grab Foursquare location data from an IFTTT-generated text file
# Because of the Grep searches, this will work best with this recipe: https://ifttt.com/recipes/187849
# Change line 15 with the location of your IFTTT file
# Make sure to change line 25 with your personal client ID and secret generated by Foursquare
# Once you have the data, you can output or write it however you like.
