 367             Calculates the title and album gains/peaks of the given FLAC
 368             files as if all the files were part of one album, then stores
 369             them as FLAC tags.  The tags are the same as
 370             those used by vorbisgain.  Existing ReplayGain tags will be
 371             replaced.  If only one FLAC file is given, the album and title
 372             gains will be the same.  Since this operation requires two
 373             passes, it is always executed last, after all other operations
 374             have been completed and written to disk.  All FLAC files
 375             specified must have the same resolution, sample rate, and
 376             number of channels.  The sample rate must be one of 8, 11.025,
 377             12, 16, 18.9, 22.05, 24, 28, 32, 37.8, 44.1, 48, 56, 64, 88.2,
 378             96, 112, 128, 144, 176.4, or 192kHz.

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