+ * taken from debian-utils. I've only removed the long options and a the
+ * 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.
