Agustin:
Also from the Getopt::Std man page:
For those of you who don't like additional global vari-
ables being created, getopt() and getopts() will also
accept a hash reference as an optional second argument.
Hash keys will be x (where x is the switch name) with key
values the value of the argument or 1 if no argument is
specified.
