Tags extracted from Mac OS resource files, DFONT files and "._" sidecar
files. These tags may also be extracted from the resource fork of any file
in OS X, either by adding "/..namedfork/rsrc" to the filename to process the
resource fork alone, or by using the ExtractEmbedded (-ee) option to process
the resource fork as a sub-document of the main file. When writing,
ExifTool preserves the Mac OS resource fork by default, but it may deleted
with -rsrc:all= on the command line.
