              mac-align mode
                     Align all selected tracks on Macintosh GCR disks relative
                     to the index.  Possible values for mode are:

                            with the index.

                     gap-end
                            Align  the  end of the longest gap between sectors
                            with the index.

                     index  Align the start of the first  sector  on  a  track
                            with the index.

                            bered sector with the index.

                     sector-id
                            Align the start of the lowest numbered sector with

              mfm-align-am what pos
                     Rotate the track such that the first address mark of type
                     what on the track is at bit position pos. Possible values
                     for what are:

                     all    All address mark types

                     iam    Index address marks

                     idam   ID address marks

                     dam    Data address marks

                     Multiple types can be combined by joining them with a '+'
                     or a '-' sign.  For example, the type  all-iam  specifies
                     all address mark types except index address marks.

              new    Create new tracks.

              rotate cnt
                     Rotate  all  selected  tracks left by cnt bits. If cnt is
                     negative, the track is rotated right.

              rotate-angle angle
                     Rotate all selected tracks left by angle degrees. If  an-
                     gle is negative, the track is rotated right.

              save filename
                     Save all selected tracks to filename. The contents of the
                     tracks are written sequentially to the file.

              weak-clean
                     Clean up the weak bit events on all selected tracks.

              weak-close max
                     If two weak bits are separated  by  up  to  max  non-weak
                     bits, turn all non-weak bits in between into weak bits.

              weak-detect max
                     Detect  weak  bits. All zero bits that are preceded by at
                     least max zero bits are mared as weak.

              weak-expand left right
                     Expand runs of weak bits by adding left weak bits  before
                     every weak bit and right weak bits after every weak bit.

              weak-load filename
                     Load  the weak bit mask of all selected tracks from file-
                     name. The weak bit masks are of  the  same  size  as  the
                     track data.

              weak-open max
                     Remove all runs of up to max weak bits.

              weak-save filename
                     Save  the  weak  bit mask of all selected tracks to file-
                     name. The weak bit masks are of  the  same  size  as  the
                     track data.

              weak-set val
                     Set  bits that are marked as weak to val which can be one
                     of the following:

                     0      Set bits to 0

                     1      Set bits to 1

                     flip   Invert bits

                     random Set bits to a random value

       -r, --data-rate rate
              Set the default data rate. The default is  500000.  If  rate  is
              greater than 1000 it is assumed to be in bits per second, other-
              wise it is assumed to be in kbits per seconds.

       -s, --set parameter value
              Set a parameter value. Recognized parameters are:

              mac-align mode
                     When decoding Macintosh GCR tracks to  text,  align  them
                     using  mode.  The  rotation required for the alignment is
                     recorded in the text output and undone when the  text  is
                     re-encoded,  so this alignment is purely for readability.
                     See the -p mac-align operation for a description  of  the
                     possible values for mode.

                     Set the FM clock rate (this is twice the data rate).  The
                     default is 250000, suitable for single density disks.

              fm-iam boolean
                     If  false,  skip  the  index address mark. The default is
                     false.
