  * taken from debian-utils. I've only removed the long options and 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.
- * -e           exit as soon as a script returns with a non-zero exit code
