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

SYNOPSIS
use Getopt::Long::Descriptive;
my ($opt, $usage) = describe_options( ... );
$usage->text; # complete 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.
