# This script was made to automate the deployment process.
# It was made to run inside the webapps directory.
# If you switch directories, you must also make sure the variable paths are updated.
#
#
# After it removes the old .war file, 
# the user is responsible for uploading the new .war file to this directory.
# The user is also responsible for entering the password when the server restarts. 
#
# to run: 
# 	./redeploy
#
# If you updated any domains, you will have to flush the database,
# and reupload any test data,
# otherwise deployment will fail due to database errors.
# to do this, run this script with the -f or --flush flag: 
#
# 	./redeploy -f
# OR
# 	./redeploy --flush
#
# If you use my script for your project,
# you will have to modify the variables 
# so they correspond to your own project.
