id3 is an ID3 v1.1 tag editor. ID3 tags are traditionally put at the
end of compressed streamed audio files to denote information about the
audio contents. Up to thirty characters of Title, Artist, and Album
information can be stored, as well as a 28-character comment, four-
digit year, track number up to 255, and an enumerated genre.
Sets the title tag to the first 28 characters of title.
Sets the track tag to a number between 0 and 255.
Sets the artist tag to the first 28 characters of artist.
Sets the album tag to the first 28 characters of album.
Sets the year tag to the first 4 characters of year.
Sets the comment tag to the first 28 characters of comment.

-l List/view the ID3 tag.
-L List all genre tags.
-R Use rfc822-style output for tag printout.
-d Delete the ID3 tag.
The ID3 format has some shortcomings. There is a 1 in 16777216 chance
of your mp3 having a certain bit-pattern, causing id3 to write over the
last 128 bytes of your mp3 upon tag creation. If you add a track number
to an ID3 v1.0 tag, the last two characters of the comment string will
be truncated. Any bugs found in id3 should be forwarded to the author,
