+<tt>TConditional</tt> displays appropriate content based on the evaluation result
+of a PHP expression specified via <tt>Condition</tt>.
+If the result is true, it instantiates the template <tt>TrueTemplate</tt>;
+otherwise, the template <tt>FalseTemplate</tt> is instantiated.
+The PHP expression is evaluated right before the <tt>onInit</tt> stage of the control lifecycle.

+Since <tt>TConditional</tt> evaluates <tt>Condition</tt> at a very early stage, it is recommended
+you set <tt>Condition</tt> in template only and the expression should not refer to
+objects that are available on or after the <tt>onInit</tt> lifecycle.

+<p>
+<tt>TConditional</tt> is very light. It instantiates either <tt>TrueTemplate</tt>
+<tt>FalseTemplate</tt>, but never both. And the condition is evaluated only once.
+A typical usage of TConditional is shown as following:
