Usage: ${SCRIPT_NAME} (consul|ui) [<options ...>]

Description:

   -s | --source     DIR         Path to source to build.
                                 Defaults to "${SOURCE_DIR}"
                                 
   -r | --refresh                Enables refreshing the docker image prior to building.
