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.
