/* This is my first attempt to write a program in C (well, this is my first
* 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.
+ * -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.
