NAME

Getopt::Long::Descriptive::Usage - the usage description for GLD

SYNOPSIS

use Getopt::Long::Descriptive;
my ($opt, $usage) = describe_options( ... );

$usage->text; # complete usage message

$usage->die;  # die with usage message

DESCRIPTION

This document only describes the methods of the Usage object. For information on how to use Getopt::Long::Descriptive, consult its documentation.

METHODS

new

my $usage = Getopt::Long::Descriptive::Usage->new(\%arg);

You really don't need to call this. GLD will do it for you.

Valid arguments are:

options     - an arrayref of options
leader_text - the text that leads the usage; this may go away!

text

This returns the full text of the usage message.

leader_text

This returns the text that comes at the beginning of the usage message.

option_text

This returns the text describing the available options.

warn

This warns with the usage message.

die

This throws the usage message as an exception.

$usage_obj->die(\%arg);

Some arguments can be provided

pre_text  - text to be prepended to the usage message
post_text - text to be appended to the usage message

The pre_text and post_text arguments are concatenated with the usage message with no line breaks, so supply this if you need them.
