1 id3ed edits the "id3" tag for mpeg layer3 files. The mpeg3
2 specification does not provide any method for storing song
3 information, however the id3 tag has become a standard method for
4 doing this, and most mp3 players can read the tag. It will not cause
5 any errors in players that do not support it. The tag is 128 bytes
6 long and is located at the end of the file.
