+coefficient of variation. Statistics are calculated separately for every
+category/zone found in the <b>zones</b> input map if given.
 If the <b>-e</b> extended statistics flag is given the 1st quartile, median,
 3rd quartile, and given <b>percentile</b> are calculated.
 If the <b>-g</b> flag is given the results are presented in a format suitable
 for use in a shell script.
+If the <b>-t</b> flag is given the results are presented in tabular format
+with "|" as field separator. The table can immediately be converted to a
+vector attribute table which can then be linked to a vector, e.g. the vector
+that was rasterized to create the <b>zones</b> input raster.
