Usage: ${SCRIPT_NAME} [<options ...>]
Description:
This script uses the date of the last checkin on the branch as the build date. This
is to make the date consistent across the various platforms we build on, even if they
start at different times. In practice this is the commit where the version string is set.
Options:
-s | --source DIR Path to source to build.
Defaults to "${SOURCE_DIR}"
