+ * ---------------------
+ * This exception is thrown by calls to the <code>error</code>
+ * function.  Typical code for catching errors looks like this:

+ *       ... code in which an error might occur ...
+ *    } catch (ErrorException & ex) {
+ *       ... code to handle the error condition ...
+ *    }
+ *</pre>
+ *
+ * If an <code>ErrorException</code> is thrown at any point in the
+ * range of the <code>try</code> (including in functions called from
+ * that code), control will jump immediately to the error handler.
