Changes in version 2.35
-----------------------
:
* Options can take multiple values at once. E.g.,

    --coordinates 52.2 16.4 --rgbcolor 255 255 149

  To handle the above command line, the following call to GetOptions
  can be used:

    GetOptions('coordinates=f{2}' => \@coor, 'rgbcolor=i{3}' => \@color);

  You can specify the minimum and maximum number of values desired.
  The syntax for this is similar to that of regular expression
  patterns: { min , max }.
