refactored the cmdline argument processing I replaced the nested switch statements with one single large else-if construct. Instead of char comparision now str(n)cmp(3) is used. Although this is slower it is much more readable and covers corner-cases which were uncovered before (e.g. -bdxxx). As always: Readability and simplicity matter, not performance.
