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.
