+ Like --set-tag, except the VALUE is a filename whose
+ contents will be read verbatim to set the tag value.
+ Unless --no-utf8-convert is specified, the contents will be
+ converted to UTF-8 from the local charset. This can be used
+ to store a cuesheet in a tag (e.g.
+ --set-tag-from-file="CUESHEET=image.cue"). Do not try to
+ store binary data in tag fields! Use APPLICATION blocks for
+ that.
