+<h2>DESCRIPTION</h2>
+
+<em>db.droptable</em> drops an attribute table.
+If the <b>-f</b> force flag is not given then nothing is removed, instead
+a preview of the action to be taken is printed.
+
+<h2>NOTES</h2>
+
+<em>db.droptable</em> is a front-end to <em>db.execute</em> to allow easier
+usage. To some extent it is verified if the table is connected to a vector map.
+
+<h2>EXAMPLES</h2>
+
+Dropping a table (Spearfish):
+<p>
+<div class="code"><pre>
+# work on own copy
+g.copy vect=roads,myroads
+
+# only shows what would happen
+db.droptable myroads
+
+# actually drop the table
+db.droptable -f myroads
+
+db.tables -p
+</pre></div>
