Usage: ${0##*/} [-h] [-v] [--op-build-dir=OP_BULD_DIR] [--skip-link]

This script takes the witherspoon_defconfig file from OP_BUILD_DIR and creates
the swift_defconfig file by replacing swift-specific fields.  It then links the
swift_defconfig and swift.config files into the right sub-directories of
OP_BUILD_DIR.
NOTE: If no OP_BUILD_DIR is provided, this script will clone op-build into the
current directory.

    -h,--help                   Display this help and exit
    -v                          Verbose mode. Can be used multiple times for
                                increased verbosity.
    --op-build-dir=OP_BULD_DIR  Uses the directory (incuding its path) for
                                op-build repo instead of the default ./op-build
    ---skip-link                Skips linking the config files into the right
                                sub-directories of OP_BUILD_DIR

Example - No argements:
    ./setup_swift

Example - All argements:
    ./setup_swift -v -v --skip-link --op-build-dir=/<some>/<path>/<to>/op-build
