35 * report mode. As the original run-parts support only long options, I've
36 * broken compatibility because the BusyBox policy doesn't allow them.
37 * The supported options are:
38 * -t test. Print the name of the files to be executed, without
40 * -a ARG argument. Pass ARG as an argument the program executed. It can
41 * be repeated to pass multiple arguments.
42 * -u MASK umask. Set the umask of the program executed to MASK. */
