now we can:
- parse short options, those beginning with a hypnen '-'
- parse long options, those beginning with two hyphens '--'
- long options can have arguments in two forms:
- either with an equal sign, e.g.: --opion-name=argument
- or with a space, e.g: --option argument
in the latter case we can have more than one argument, e.g: --option argument1 argument2
- parse non-option arguments, those after two hyphens to the end of a string, e.g: -- arg1 arg2
