cdrdao.

Are you sure you're not confusing TOC and CUE here?

If the TOC file was created by cdrdao, it will the catalogue number,
track and index positions (for both audio and data tracks), copy and
pre-emphasis flags, pre-gaps, track ISRC codes, at least CD-Text
subchannel information.

I think you must be confusing TOC and CUE. CUE is sidely used; TOC is
not: only cdrdao uses it as far as I know. The TOC file format is quite
well documented (over 400 lines of documentation, including examples) in
the cdrdao manual page.

You're still going to use the time anyway; you must uncompress before
burning. So you'll save only the diskspace for the uncompressed image.
I personally don't think it's that worthwhile; anybody with any number
of FLAC compressed CD images around is not going to be wanting for less
than 800 MB of free disk space.
