# This script builds a tar file that contains a bunch of deps that OBS needs for
# advanced functionality on OSX. Currently this tar file is pulled down off of s3
# and used in the CI build process on travis.
# Mostly this sets build flags to compile with older SDKS and make sure that
# the libs are portable.
