#
# Description:  Sample user configuration file for Image::ExifTool
#
# Notes:        This example file shows how to define your own shortcuts and
#               add new EXIF, IPTC, XMP, PNG, MIE and Composite tags, as well
#               as how to specify preferred lenses for the LensID tag, and
#               define new file types and default ExifTool option values.
#
#               Note that unknown tags may be extracted even if they aren't
#               defined, but tags must be defined to be written.  Also note
#               that it is possible to override an existing tag definition
#               with a user-defined tag.
#
#               To activate this file, rename it to ".ExifTool_config" and
#               place it in your home directory or the exiftool application
#               directory.  (On Mac and some Windows systems this must be done
#               via the command line since the GUI's may not allow filenames to
#               begin with a dot.  Use the "rename" command in Windows or "mv"
#               on the Mac.)  This causes ExifTool to automatically load the
#               file when run.  Your home directory is determined by the first
#               defined of the following environment variables:
#
#                   1.  EXIFTOOL_HOME
#                   2.  HOME
#                   3.  HOMEDRIVE + HOMEPATH
#                   4.  (the current directory)
#
#               Alternatively, the -config option of the exiftool application
#               may be used to load a specific configuration file (note that
#               this must be the first option on the command line):
#
#                   exiftool -config example.config ...
#
#               This example file defines the following 16 new tags as well as
#               a number of Shortcut and Composite tags:
#
#                   1.  EXIF:NewEXIFTag
#                   2.  GPS:GPSPitch
#                   3.  GPS:GPSRoll
#                   4.  IPTC:NewIPTCTag
#                   5.  XMP-xmp:NewXMPxmpTag
#                   6.  XMP-exif:GPSPitch
#                   7.  XMP-exif:GPSRoll
#                   8.  XMP-xxx:NewXMPxxxTag1
#                   9.  XMP-xxx:NewXMPxxxTag2
#                  10.  XMP-xxx:NewXMPxxxTag3
#                  11.  XMP-xxx:NewXMPxxxStruct
#                  12.  PNG:NewPngTag1
#                  13.  PNG:NewPngTag2
#                  14.  PNG:NewPngTag3
#                  15.  MIE-Meta:NewMieTag1
#                  16.  MIE-Test:NewMieTag2
