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