+<p>The <codeph>CleanupDeletePushL()</codeph> templated function constructs
+and pushes a <codeph>TCleanupItem</codeph> onto the cleanup stack. When <codeph>CleanupStack::PopAndDestroy()</codeph> is
+called, the object encapsulated by the <codeph>TCleanupItem</codeph> is deleted.</p>
+<codeblock id="GUID-6AED7BDB-9CB8-588A-A286-AEAEECDB6868" xml:space="preserve">...
+CTestOne* one = new (ELeave) CTestOne;
+CleanupDeletePushL(one);
+one-&gt;SetTextL(KTxtHelloWorld);
+CleanupStack::PopAndDestroy();
+...</codeblock>
+<p>The <codeph>TCleanupItem</codeph> object encapsulates a pointer to the <codeph>CTestOne</codeph> object;
+the cleanup operation is the static function <codeph>Delete()</codeph> of
+the templated class <codeph>CleanupDelete&lt;class T&gt;</codeph>. This is implemented
+by simply deleting <codeph>CTestOne</codeph>.</p>
