	    Calculates the title and album gains/peaks of the given FLAC
	    files as if all the files were part of one album, then stores
	    them in the VORBIS_COMMENT block.  The tags are the same as
	    those used by vorbisgain.  Existing ReplayGain tags will be
	    replaced.  If only one FLAC file is given, the album and title
	    gains will be the same.  Since this operation requires two
	    passes, it is always executed last, after all other operations
	    have been completed and written to disk.  All FLAC files
	    specified must have the same resolution, sample rate, and
	    number of channels.  The sample rate must be one of 8, 11.025,
	    12, 16, 22.05, 24, 32, 44.1, or 48 kHz.

	<listitem>
	  <para>
	    Add seek points to a SEEKTABLE block.  Using #, a seek point at
	    that sample number is added.  Using X, a placeholder point is
	    added at the end of a the table.  Using #x, # evenly spaced seek
	    points will be added, the first being at sample 0.  Using #s, a
	    seekpoint will be added every # seconds (# does not have to be a
	    whole number; it can be, for example, 9.5, meaning a seekpoint
	    every 9.5 seconds).  If no SEEKTABLE block exists, one will be
	    created.  If one already exists, points will be added to the
	    existing table, and any duplicates will be turned into placeholder
	    points.  You may use many --add-seekpoint options; the resulting
	    SEEKTABLE will be the unique-ified union of all such values.
	    Example: --add-seekpoint=100x --add-seekpoint=3.5s will add 100
	    evenly spaced seekpoints and a seekpoint every 3.5 seconds.
