21 * report mode. As the original run-parts support only long options, I've
22 * broken compatibility because the BusyBox policy doesn't allow them.
23 * The supported options are:
24 * -t test. Print the name of the files to be executed, without
26 * -a ARG argument. Pass ARG as an argument the program executed. It can
27 * be repeated to pass multiple arguments.
28 * -u MASK umask. Set the umask of the program executed to MASK. */
31 * done - convert calls to error in perror... and remove error()
32 * done - convert malloc/realloc to their x... counterparts
33 * done - remove catch_sigchld
34 * done - use bb's concat_path_file()
35 * done - declare run_parts_main() as extern and any other function as static?
