21 /* This piece of code is heavily based on the original version of run-parts,
22 * taken from debian-utils. I've only removed the long options and a the
23 * report mode. As the original run-parts support only long options, I've
24 * broken compatibility because the BusyBox policy doesn't allow them.
25 * The supported options are:
26 * -t test. Print the name of the files to be executed, without
28 * -a ARG argument. Pass ARG as an argument the program executed. It can
29 * be repeated to pass multiple arguments.
30 * -u MASK umask. Set the umask of the program executed to MASK.
