Ok, I download stuff from the internet so sue me! Since I'm an iSheep I want to use my iPod/iPhone to listen to to my audiobooks that I download. The problem with this is that all releases are in MP3 format and this messes up my play lists when doing a shuffle of all songs; all of a sudden there is a chapter from an audiobook read. So, what to do. A cupple of months ago I wrote a script that converted m3u to m4b, and now I've rewritten it. So, here it is! Execute the script with directory-with-m3u-files as argument.
