 <h2>DESCRIPTION</h2>
 
 The module <em>t.remove</em> removes space time datasets (STRDS, STR3DS,
-STVDS) from the temporal database. In other words, it deletes the relevant
-database entries and not the maps.

 <p>
 Optionally, also the raster, 3D raster and vector maps of the space time
-datasets can be removed using the <b>-r</b> (recursive) and <b>-f</b>
-(force) flags. Recursive removal works only if both flags are checked
-(use <b>-rf</b>).
+datasets can be removed from the current mapset using the <b>-r</b> (recursive)
+and <b>-f</b> (force) flags. This recursive removal only works if both flags

 <h2>EXAMPLE</h2>
 
 In this example a space time raster dataset (STRDS) named
 <b>precip_months_sum</b> will be created using a subset of the monthly
 precipitation raster maps from the North Carolina climate sample data set.
-In order to be able to show case recursive removal without deleting original
-sample data, new data is generated by means of computing yearly precipitation
-sums. Finally, all newly produced data (STRDS and raster maps) is removed again.
