 Special characters:
 
- "-"    A dash as the first char in a opt_complementary group forces
-        all arguments to be treated as options, even if they have

+ "-"    A group consisting of just a dash forces all arguments

-        opt_complementary = "-:w-x:x-w";
-        getopt32(argv, "wx");
+        opt_complementary = "-:w-x:x-w"; // "-w-x:x-w" would also work,
+        getopt32(argv, "wx");            // but is less readable
 
-        Allows any arguments to be given without a dash (./program w x)
+        This makes it possible to use options without a dash (./program w x)
         as well as with a dash (./program -x).
 
         NB: getopt32() will leak a small amount of memory if you use
