#  The while-done structure defines a loop that executes once for each option
# in the getopts - option structure. The ":h" string - which requires the quotes
# - lists the possible input options that will be evaluated by the case - esac
# structure. Each option listed must have a corresponding stanza in the case statement.
# exit;; exits from the program without executing any more code even if some
# exists. The option processing loop is also terminated, so no additional
# options would be checked
