### This script builds a binary distribution of GF from the source
### package that this script is a part of. It assumes that you have installed
### the Haskell Platform, version 2013.2.0.0 or 2012.4.0.0.
### Two binary package formats are supported: plain tar files (.tar.gz) and
### OS X Installer packages (.pkg).
