Is there a good command-line ID3 tool for OS X?

Anyone know of a command-line***** ID3 tool, with support for **ID3v2**, that you can get working on Mac OS X with reasonable effort? It should support both reading and writing tags. (***** I want to be able to call it e.g. from some Python scripts, so a GUI tool won't do.) The id3tool utility is otherwise good, but doesn't support ID3v2 (and thus doesn't play that well with iTunes). I had to compile it from source, but that was pretty straightforward on a Mac with Xcode & developer tools (including, notably, a C compiler). Anyway, I'd especially like something with similar command-line options as id3tool. Here's an example of tagging one file: id3tool -t "Song Title" -r Artist -a "Album Name" -c 2 track-02.mp3
