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.

Name

Perl Version

       This library should run on perls released even a long time ago.  It should work on any version of perl
       released in the last five years.

       Although it may work on older versions of perl, no guarantee is made that the minimum required version
       will not be increased.  The version may be increased for any reason, and there is no promise that patches
       will be accepted to lower the minimum required perl.

Synopsis

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

         $usage->text; # complete usage message

         $usage->die;  # die with usage message

Version

       version 0.116
