+ * const struct option *longopts,
+ * const char *commandname,
+ * int num_opts_req) { ...
+ *
+ * opt: pointer to an int variable, holds the current option
+ * during processing.
+ * opts: short options, as per getopt_long(3)'s optstring
argument.
+ * longopts: long options, as per getopt_long(3)'s longopts argument.
+ * May be null.
+ * commandname: name of this command, for usage string.
+ * num_required_opts: number of non-option command line parameters
+ * which are required.
+ *
+ * In addition the calling context is expected to contain variables
+ * "argc" and "argv" in the conventional C-style:
+ * main(int argc, char **argv)
+ * manner.
+ *
+ * Callers should treat SWITCH_FOREACH_OPT as they would a switch
+ * statement over the value of `opt`. Each option given in `opts` (or
+ * `lopts`) should be handled by a case statement as if it were inside
+ * a switch statement.
+ *
+ * In addition to the options provided in opts callers must handle
+ * two additional pseudo options:
+ * 0 -- generated if the user passes a -h option. help will be printed,
+ * caller should immediately return 0.
+ * 2 -- generated if the user does not provided `num_required_opts`
+ * non-option arguments, caller should immediately return 2.
+ *
+ * Example:
+ *
+ * int main_foo(int argc, char **argv) {
+ * int opt;
+ *
+ * SWITCH_FOREACH_OPT(opt, "blah", NULL, "foo", 0) {
+ * case 0: case2:
+ * return opt;
+ * case 'b':
+ * ... handle b option...
+ * break;
+ * case 'l':
+ * ... handle l option ...
+ * break;
+ * case etc etc...
+ * }
+ * ... do something useful with the options ...
+ * }
