DESCRIPTION

This module is used to generate the tag lookup tables in Image::ExifTool::TagLookup.pm and tag name documentation in Image::ExifTool::TagNames.pod, as well as HTML tag name documentation. It is used before each new ExifTool release to update the lookup tables and documentation, but it is not used otherwise. It also performs some validation and consistency checks on the tag tables.

SYNOPSIS

$builder = new Image::ExifTool::BuildTagLookup;
$ok = $builder->WriteTagLookup('lib/Image/ExifTool/TagLookup.pm');
$ok = $builder->WriteTagNames('lib/Image/ExifTool/TagNames.pod','html');
