NAME
       Image::ExifTool::BuildTagLookup - Build ExifTool tag lookup tables

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
         use Image::ExifTool::BuildTagLookup;

         $builder = new Image::ExifTool::BuildTagLookup;

         # update Image::ExifTool::TagLookup
         $ok = $builder->WriteTagLookup('lib/Image/ExifTool/TagLookup.pm');

         # update the tag name documentation
         $ok = $builder->WriteTagNames('lib/Image/ExifTool/TagNames.pod','html');

         # print some statistics
         my $count = $$builder{COUNT};
         foreach (sort keys %$count) {
             printf "%5d %s\n", $$count{$_}, $_;
         }

MEMBER VARIABLES
       PRESERVE_DATE
           Flag to preserve "Last revised" date in HTML files.  Set before calling
           WriteTagNames().

       COUNT
           Reference to hash containing counting statistics.  Keys are the descriptions, and
           values are the numerical counts.  Valid after BuildTagLookup object is created, but
           additional statistics are added by WriteTagNames().

       WRITE_PSEUDO
           Returned list of writable pseudo tags.
