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

-/* TODO
- * done - convert calls to error in perror... and remove error()
- * done - convert malloc/realloc to their x... counterparts
- * done - remove catch_sigchld
- * done - use bb's concat_path_file()
- * done - declare run_parts_main() as extern and any other function as static?
+ * -t test. Print the name of the files to be executed, without
+ * execute them.
+ * -a ARG argument. Pass ARG as an argument the program executed. It can
+ * be repeated to pass multiple arguments.
+ * -u MASK umask. Set the umask of the program executed to MASK.
