I have some old rips without .cue sheets and log files and i was wondering if you could still match them against the AR database. I mostly use cuetools with a .cue to do that but still I'm not aware of full functionality of the software.
CUE Sheet Wiki (http://wiki.hydrogenaudio.org/index.php?title=Cue_sheet)
CUE Tools has a "CUE Sheet Creator..." button that will create a CUE sheet for you.
you can also use foobar2000's verifier.
