# Purpose: Bash script to install PiE server
#	1) create a python3 virtual environment in pie_env/
#	2) install pie_app/requirements.txt
#	3) install a systemctl service treadmill.service
#
# Usage:
#	./install-pie
#
# Once this is all done, the PiE server can be used as follows
#
#	cd ~/pie
#	./pie start
#	./pie stop
#	./pie restart
#	./pie status
#	./pie enable		# start pie server at boot
#	./pie disable		# do not start pie server at boot
#
#	./pie run			# run the PiE server on command line, useful for debugging

#if [ $(id -u) = 0 ]; then
#   echo "Do not run with sudo. Try again without sudo"
#   exit 1
#fi
