NAME
       getopt - Process single-character switches with switch
       clustering

       getopts - Process single-character switches with switch
       clustering

SYNOPSIS
           use Getopt::Std;

           getopt('oDI');    # -o, -D & -I take arg.  Sets opt_* as a side effect.
           getopt('oDI', \%opts);    # -o, -D & -I take arg.  Values in %opts
           getopts('oif:');  # -o & -i are boolean flags, -f takes an argument
                             # Sets opt_* as a side effect.
           getopts('oif:', \%opts);  # options as above. Values in %opts


DESCRIPTION
       The getopt() functions processes single-character switches
       with switch clustering.  Pass one argument which is a
       string containing all switches that take an argument.  For
       each switch found, sets $opt_x (where x is the switch
       name) to the value of the argument, or 1 if no argument.
       Switches which take an argument don't care whether there
       is a space between the switch and the argument.

       Note that, if your code is running under the recommended
       use strict 'vars' pragma, it may be helpful to declare
       these package variables via use vars perhaps something
       like this:

           use vars qw/ $opt_foo $opt_bar /;

       For those of you who don't like additional variables 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.
