# This script simply clones this project itself and changes the name of the deb package generated including other required adjustments.
#
# This is useful to create a new but similar debian package that can be used to package another Spring Boot application.
#
# The generated output will be placed inside the out directory.
#
# How to run this script:
#  ./create-new-project.sh name-of-new-deb-package 
# 
# Example:
#  ./create-new-project.sh mycompany-webapp
