	# This script can be used for building multiple react-native apps from a single git repo.
	# It needs master files for the default configurations.
	# master files are generally the copy of the current config files of that git repo.
	# If current state of the app changes i.e. adding new 3rd party components so package.json changes;
	# then one should be responsible to reflect these changes to the master files to be synced with the current state of the repo.
	# This script can be used to alter the current state, so that new apps could be generated with new names etc.
	# scriptAndroid.sh
	# "chmod +x ./scriptAndroid" to make script executable.
