I suppose it's not widely known, but what really matters is the copying
permission notices in the files themselves.  So indeed, this should be
gpl2+.

If it includes a library, then I think it should be named
'python-eyed3'.  This is our usual convention, and it has the advantage
that we can add 'python2-eyed3' later, in case someone wants it.

Also, your mail client seems to have applied word-wrapping to the patch,
so some of the "+" signs have been wrapped into the description.  This
is what I see:

--8<---------------cut here---------------start------------->8---
+    (description
+     "Eyed3 is a command-line editor to add/edit/remove ID3-tags on mp3
files. +It supports version 1.0, 1.1, 2.3 and 2.4 of the ID3 standard.
Additionally it +displays several information about the file such as length
and bitrate from an +MP3 file.")
--8<---------------cut here---------------end--------------->8---

This makes it difficult for us to apply it, since we'd have to fix it up
by hand.  Can you persuade your mail client to avoid word-wrapping?  You
could make it an attachment if needed.

     Thanks!
