    Tag guessing pattern:
        This is a pattern that will be used to guess the tag names of files
        that do not have any tags. The pattern is a string with the following
        variables:
            %{album} - The album name
            %{albumartist} - The album artist name
            %{artist} - The artist name
            %{disc} - The disc number - 1 digit
            %{genre} - The genre name
            %{releasecountry} - The country of the release - 2 letter code
            %{title} - The title of the track
            %{track} - The track number - 2 digits
            %{year} - The year or date of the album
	EODesc
	read 				\

		-i"${tagguessing}	\

		tagguessing
	cat <<-EODesc

    Tag guessing trigger(s):
        Tags whose absence will trigger tag guessing.
            album - The album name
            albumartist - The album artist name
            artist - The artist name
            disc - The disc number
            genre - The genre name
            releasecountry - The country of the release
            title - The title of the track
            track - The track number
            year - The year or date of the album
