The flac command manual: an inconsistency?

Hi:
I write here because flac and cdrecord are programs present in slack 12. IDK if in other distros as well.

I have these two files in a directory. The .cue contains the indexes to split the .flac.

Code:

CD6\ Nos.22,23,24,25,26.cue
CD6\ Nos.22,23,24,25,26.flac

It's my intention to create an audio CD from the .flac. From flac manual:

Code:

DECODING OPTIONS
       --cue=[#.#][-[#.#]]
              Set the beginning and ending cuepoints to decode.  The optional first #.# is the track and index
              point  at  which  decoding will start; the default is the beginning of the stream.  The optional
              second #.# is the track and index point at which decoding will end; the default is  the  end  of
              the  stream.  If the cuepoint does not exist, the closest one before it (for the start point) or
              after it (for the end point) will be used.  If those don't exist, the start of the  stream  (for
              the  start  point)  or  end  of  the stream (for the end point) will be used.  The cuepoints are
              merely translated into sample numbers then used as --skip and --until.

From the .cue:

Code:

  TRACK 01 AUDIO
    TITLE "Piano Sonata No.22 in F minor, op.54 - I. In Tempo d'un Menuetto"
    INDEX 00 00:00:00
    INDEX 01 00:00:33
  TRACK 02 AUDIO
    TITLE "Piano Sonata No.22 in F minor, op.54 - II. Allegretto - Piu Allegro"
    INDEX 00 05:15:55
    INDEX 01 05:17:45

In principle, I could do

Code:

flac --decode --cue=01.00-02.00 "CD6\ Nos.22,23,24,25,26.flac"

and to have the first track decoded and ready to be fed to cdrecord. But this is sheer nonsense. How could flac know he must decode from 00:00:00 to 05:15:55 without a reference to the cuefile? I can't find a way out. Any idea?

Flac files can optionally have cuesheet data embedded inside them. See, for example, the flac command's encoding option --cuesheet=filename. If your flac file was not originally encoded with embedded cuesheet information, you can add it now from your cue file using the metaflac command.
