#   Script:  prep_codesign.sh
#
#   Synosis: prep_codesign.sh <App>
#
#   Description
#	Use for Unity Mac build only.  When an Agora Unity Project gets built,
#   the framework library symbolic link structure gets lost.  This script will
#   restore the symlink structure inside the AgoraRTCKit frame work.
#	
#	For a reference to the original framework structure, you may also take
#   a look at the online download zipped version and look inside the bundle.
#	
#   Usage:
#   *	Use for preparation for codesign and distribution that requires Apple 
#	notarization.
#
#   *	Run this from the build directory where your Mac build ("YourApp.app") is.
#	Build the Unity Project and execute this script, for example:
#	    ./prep_codesign.sh YourApp.app
#   *   A entitlement file "App.entitlements" will be created.  Use that for your
#	codesign --entitlements option.
