=head1 NAME

Image::ExifTool::InDesign - Read/write meta information in Adobe InDesign files

=head1 SYNOPSIS

This module is used by Image::ExifTool

=head1 DESCRIPTION

This module contains routines required by Image::ExifTool to read XMP
meta information from Adobe InDesign (.IND, .INDD and .INDT) files.

=head1 LIMITATIONS

1) Only XMP meta information is processed.

2) A new XMP stream may not be created, so XMP tags may only be written to
InDesign files which previously contained XMP.

3) File sizes of greater than 2 GB are supported only if the system supports
them and the LargeFileSupport option is enabled.
