    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.
