    1.16 +    which start with either "-" or "/". Both kinds can be allowed or
    1.17 +    disallowed, see allow_long and allow_short. The allowed character
    1.18 +    for short options is also configurable.
    1.19 +
    1.20 +    Option's value can be specified in the same token as name
    1.21 +    ("--foo=bar"), or in the next token.
    1.22 +
    1.23 +    It's possible to introduce long options by the same character as
    1.24 +    short options, see allow_long_disguise.
    1.25 +
    1.26 +    Finally, guessing (specifying only prefix of option) and case
    1.27 +    insensitive processing are supported.
