+<h2>DESCRIPTION</h2>
+
+<em>r.rot90</em> rotates a raster array by 90 degrees clockwise.
+
+<h2>NOTES</h2>
+
+The entire map must be loaded into memory, which may be a problem
+for large rasters. The coordinates of the northern and southern
+bounds of the map will be flipped to satisfy the N > S requirement.
+It is likely that the user will want to use the <em>r.region</em>
+module to reset the bounds regardless.
+
+
+<h2>REQUIREMENTS</h2>
+
+<a href="http://www.gnu.org/software/octave/">GNU Octave</a>.
+
+
+<h2>TODO</h2>
+
+Either rewrite as a C module (see the code from GRASS 5's m.rot90
+module) or use NumPy/SciPy to do the work, as the Python libraries
+may be more commonly installed than GNU Octave.
