# A simple script to keep in sync one folder on local host with a remote host. I use it to keep my code synced with
# a RaspberryPi while I edit it on my desktop.
# 
# NOTE 1: make sure that you copy your keys to remote host with `ssh-copy-id` 
# first to allow for rsync to run without password prompts.
# NOTE 2: set the variables below to suit your needs.
