+      <emphasis>cell</emphasis> models a classical 1D cellular

+      identified by <emphasis>ioutFunc</emphasis>.
+    </para>
+    <para>
+      <emphasis>initStateFunc</emphasis> is an input vector containing
+      the inital value of the row of cells, while
+      <emphasis>iRuleFunc</emphasis> is an input vector containing the
+      chosen rule in the binary form (least significant bit first). 
+    </para>
+    <para>
+      A new generation of cells is evaluated each time
+      <emphasis>ktrig</emphasis> contains a non-zero value.  Also the
+      status of all cells can be forced to assume the status
+      corresponding to the contents of
+      <emphasis>initStateFunc</emphasis> each time
+      <emphasis>kreinit</emphasis> contains a non-zero value.
+    </para>
+    <para>
+      Note that each cell is supposed to be in one of two possible
+      states (1 = "alive", 0 = "dead"), although fractional values
+      should work too, because truncation is used.
