# This script will automates the steps used to producing a static osx
# package of SoX.
#
# It requires to already have several external libraries already installed
# under /usr/local/10.9.  The external libraries must be static only or else
# it will expect dylib versions to already exist on external boxes.
#
# This goes out of its way to use the oldest available SDK for greater
# compatibility.
#
# Various notes:
#
# The following command lines were used to generate the static external
# libraries SoX ships with.
