Showing how to combine short (-h) posix options with long-form (--help) gnu-like options while using getopts.

It seems overkill for smaller applications which are probably best off with a simple snippet like:

while :; do
    case "$1" in
    -f | --file) BEMOJI_CUSTOM_LIST="${OPTARG}"; shift 2 ;;
    -h | --help) usage 0 ;;
    -p | --private) bm_private_mode=true; shift ;;
    -v | --version) version ;;
    -*) usage 1 ;;
    *) break ;;
    esac
done

for option gathering, but for more complex setups this could be the way to go.
