Well I guess better late than never...

I have finally managed to take a closer look at the problem. I ahve
decided to implement a library from scratch. 

So far it can read most of the information on tracks (as opposed to
playlists). Writing is not yet supported. But the library is designed in
a way that makes it possible to update single entries without rewriting
all the whole file. 

I think it might also be a bit faster than the gtkpod implementation.
But I have not measured that. However the test program takes about
127 milliseconds to read a 1779 songs iTunesDB on a 2.4 GHz Pentium 4M
(output piped to /dev/null).

So far the library is only 6480 bytes large (stripped).

So far the lib does not handle converison of the iTunesDB strings
(UTF-16). And I am not sure it should. Basically I am undecided between
not handling conversion (and leaving that part to the app) or converting
everything to UTF-8. The latter has some performance and/or memory usage
advantages. What does everyone else think?

Also please comment on the api. It is not documented to well (a bit of
documentation is in itunesdb.h) but I think it should become pretty
clear by looking at the test program.

You can find the tarball at

PS: Btw. it should be really easy to change the test program to output a
shellscript to create a link-farm.
