script for automated Unity project builds

build_all.sh

#!/bin/bash

#
# This script creates builds for several platforms for a Unity project.
# It assumes this directory hierarchy:
# base_dir/
#     UnityProjectName/
#     dist/
#     dist/files/
#
# dist/ is where this script must be located
# dist/files/ is where extra files included in the build must be located (for example: README files)
# UnityProjectName/ is where the project files are. The name of this folder is located in the file `unity_config`
