NAME

6       Image::ExifTool::BuildTagLookup - Build ExifTool tag lookup tables
7

DESCRIPTION

9       This module is used to generate the tag lookup tables in
10       Image::ExifTool::TagLookup.pm and tag name documentation in
11       Image::ExifTool::TagNames.pod, as well as HTML tag name documentation.
12       It is used before each new ExifTool release to update the lookup tables
13       and documentation, but it is not used otherwise.  It also performs some
14       validation and consistency checks on the tag tables.
15

SYNOPSIS

17         use Image::ExifTool::BuildTagLookup;
18
19         $builder = new Image::ExifTool::BuildTagLookup;
20
21         # update Image::ExifTool::TagLookup
22         $ok = $builder->WriteTagLookup('lib/Image/ExifTool/TagLookup.pm');
23
24         # update the tag name documentation
25         $ok = $builder->WriteTagNames('lib/Image/ExifTool/TagNames.pod','html');
26
27         # print some statistics
28         my $count = $$builder{COUNT};
29         foreach (sort keys %$count) {
30             printf "%5d %s\n", $$count{$_}, $_;
31         }
