Is there an example flac file with subsets?

I think the .ana file created by flac -a [fname] is super easy to parse..
here is an example that reads and puts in database. after you have it in a
database you can query stuff.

this db insert work could also be done in flac/analyze.c  but i'm under
time constraints at the moment.
