-  Specify piece selection algorithm used in HTTP/FTP download. Piece
-  means fixed length segment which is downloaded in parallel in
-  segmented download. If ``default`` is given, aria2 selects piece so
-  that it reduces the number of establishing connection. This is
-  reasonable default behavior because establishing connection is an
-  expensive operation.  If ``inorder`` is given, aria2 selects piece
-  which has minimum index. Index=0 means first of the file. This will
-  be useful to view movie while downloading it.
-  :option:`--enable-http-pipelining` option may
-  be useful to reduce re-connection overhead.  Please note that aria2
-  honors
-  :option:`--min-split-size <-k>` option,
-  so it will be necessary to specify a reasonable value to
-  :option:`--min-split-size <-k>` option.
-  If ``random`` is given, aria2 selects piece randomly. Like
-  ``inorder``, :option:`--min-split-size <-k>` option is honored.
-  If ``geom`` is given, at the beginning aria2 selects piece which has
-  minimum index like ``inorder``, but it exponentially increasingly
-  keeps space from previously selected piece. This will reduce the
-  number of establishing connection and at the same time it will
-  download the beginning part of the file first. This will be useful
-  to view movie while downloading it.
