I like using etree's scripts, because they have this lovely command-line md5check utility--it'll do both md5s and FLAC fingerprints, all you have to do is point it towards the directory with the files. It's so much more pleasant if you have a disc with FLACs and SHNs because you don't have to go to one program to check the md5s and another to check the fingerprints. Simply type md5check /mnt/cdrom in the command-line and watch the output (replace /mnt/cdrom with whatever your CD drive's designation is on your OS).
