=head1 NAME
Image::ExifTool::CaptureOne - Read Capture One EIP and COS files
=head1 SYNOPSIS
This module is used by Image::ExifTool
=head1 DESCRIPTION
This module contains definitions required by Image::ExifTool to extract meta
information from Capture One EIP (Enhanced Image Package) and COS (Capture
One Settings) files.
=head1 NOTES
The EIP format is a ZIP file containing an image (IIQ or TIFF) and some
settings files (COS).
