134 Getopt::Long::Descriptive::Usage \- the usage description for GLD
136 .IX Header "SYNOPSIS"
138 \& use Getopt::Long::Descriptive;
139 \& my ($opt, $usage) = describe_options( ... );
143 \& $usage\->text; # complete usage message
147 \& $usage\->die; # die with usage message
150 .IX Header "DESCRIPTION"
151 This document only describes the methods of the Usage object. For information
152 on how to use Getopt::Long::Descriptive, consult its documentation.
158 \& my $usage = Getopt::Long::Descriptive::Usage\->new(\e%arg);
161 You \fBreally\fR don't need to call this. \s-1GLD\s0 will do it for you.
166 \& options \- an arrayref of options
167 \& leader_text \- the text that leads the usage; this may go away!
170 .IX Subsection "text"
171 This returns the full text of the usage message.
173 .IX Subsection "leader_text"
174 This returns the text that comes at the beginning of the usage message.
176 .IX Subsection "option_text"
177 This returns the text describing the available options.
179 .IX Subsection "warn"

183 This throws the usage message as an exception.
186 \& $usage_obj\->die(\e%arg);
189 Some arguments can be provided
192 \& pre_text \- text to be prepended to the usage message
193 \& post_text \- text to be appended to the usage message
196 The \f(CW\*(C`pre_text\*(C'\fR and \f(CW\*(C`post_text\*(C'\fR arguments are concatenated with the usage
