+Supported orders are:

<li><b>nsbt</b>: north -> south and bottom -> top ordering which is the default (no flags)</li>
<li><b>snbt</b>: south -> north and bottom -> top ordering using <em>-r</em> flag</li>

-The header is followed by cell values in <em>floating point</em> format.
-Cell values are output as a series of horizontal slices in row-major
-order. That is in case of the default north -> south and bottom -> top (nsbt) ordering:
-
-<div class="code"><pre>
- (x, y, z) (x + 1, y, z) ... (x + cols, y, z)
-(x, y + 1, z) (x + 1, y + 1, z) ... (x + cols, y + 1, z)
- . . .

- . . .
-(x, y + rows, z) (x + 1, y + rows, z) ... (x + cols, y + rows, z)

-
- (x, y, z + 1) (x + 1, y, z + 1) ... (x + cols, y, z + 1)
-(x, y + 1, z + 1) (x + 1, y + 1, z + 1) ... (x + cols, y + 1, z + 1)

- . . .
-(x, y + rows, z + 1) (x + 1, y + rows, z + 1) ... (x + cols, y + rows, z + 1)

-and so on.

-The data starts with the upper left corner (NW) at the bottom of the data set.

<p>One level maps can be imported with <em>r.in.ascii</em> (2D raster) using
the default <b>nsbt</b> order and removing the header lines "version",
"order", "top", "bottom" and "levels".
