So can anyone tell me how I might write a script to read this file, and translate this "simple sequence of unsigned 4-byte quantities (little-endian)" into fids that i can work with?

I have an mp3 server i wrote so I can get to my collection from wherever. I copy all the fids directories onto my webserver, and then I dump the database using emplode to CSV, import to a MySQL database, and use aPHP script to serve the files from there. I'd like to kick out that MySQL database step, and script it to use the *1 files instead.

I'm looking at fid 100 to get the contents of the root playlist, though I'm not sure what I'm looking at or how to use it..or change it to something I can use.
