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.
