# Based on http://gelisam.blogspot.com/2014/12/how-to-package-up-binaries-for.html
# This assumes binary file is called `hello-world-exe`
#
# You can test this by creatiung a new stack project:
#   $ stack new hello-world
#
# Copy this file on the directory and run:
#   $ chmod +x build-osx.sh
#   $ ./build-osx.sh
