The options to support are passed to new() as an array of arrays. Each
sub-array contains any number of String option
names which carry the same meaning, and one of the following flags:
GetoptLong::NO_ARGUMENT :
Option does not take an argument.
GetoptLong::REQUIRED_ARGUMENT :
Option always takes an argument.
GetoptLong::OPTIONAL_ARGUMENT :
Option may or may not take an argument.
The first option name is considered to be the preferred (canonical) name.
Other than that, the elements of each
sub-array can be in any order.
