VERSION
version 0.110

DESCRIPTION
This document only describes the methods of the Usage object. For information on how to use Getopt::Long::Descriptive, consult its documentation.

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.

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.
