This function works like \function{getopt()}, except that GNU style
scanning mode is used by default. This means that option and
non-option arguments may be intermixed. The \function{getopt()}
function stops processing options as soon as a non-option argument is
encountered.
If the first character of the option string is `+', or if the
environment variable POSIXLY_CORRECT is set, then option processing
stops as soon as a non-option argument is encountered.

\begin{excdesc}{GetoptError}
This is raised when an unrecognized option is found in the argument
list or when an option requiring an argument is given none.
