# File:        aerialgps.config
#
# Description: PhaseOne aerialgps namespace config file for Image::ExifTool
#
# Author:      Phil Harvey
#
# Notes:       This config file defines a new XMP namespace for the PhaseOne
#              camera 'aerialgps' tags.
#
#              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 ...
#
#              For detailed information on the definition of tag tables and
#              tag information hashes, see lib/Image/ExifTool/README.
