pptremoteagent.py

# This is a script to remote control PowerPoint presentations on macOS from your smartphone. 
# Usage:
#  * Run pptremoteserver.py on a server accessible from the internet
#  * Run pptremoteagent.py on the computer where you have PowerPoint running
#  * Open the pptremoteserver's IP address with your smartphone's browser and control the slideshow
#
# Notes:
#  * By default pptremoteagent.py polls localhost:8080. To have it poll a different address, run:
#       pptremoteagent.py -s <serverip>:<serverport>
#  * You will need to install the following Python 3 modules:
#       On server: flask
#       On agent: keyboard, requests
