# The following script will NOT copy/overwrite those files/directories:
# App_Data/
# logs/ (but backend will create it where needed)
# static/
# .env
#
# YOU NEED TO ENSURE THAT THEY EXIST MANUALLY!
#
# This script assumes that $GIT_DIR is a valid Hajk git repo.
# It will get the latest backend, client and admin and installed
# to $DEST_DIR. Backend will go directly to $DEST_DIR, while
# client and admin will be exposed via the static functionality
# built into backend. You will find the static build of them in
# $DEST_DIR/static/{admin|client}.
# You will be able to run the whole package (backend, as well as
# it serving the static client and admin apps) via one command:
# node index.js
