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. */
45 * done - convert calls to error in perror... and remove error()
46 * done - convert malloc/realloc to their x... counterparts
47 * done - remove catch_sigchld
48 * done - use bb's concat_path_file()
49 * done - declare run_parts_main() as extern and any other function as static?
