     getopt - Process single-character switches	with switch clustering

     getopts - Process single-character	switches with switch clustering

SYNOPSIS    [Toc]    [Back]

	 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    [Toc]    [Back]

     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.

     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.
