-      The <function>unserialize</function> callback function will called 
-      (with the undefined class' name as parameter), if the unserializer 
-      finds an undefined class which should be instantiated. A warning 
-      appears if the specified function is not defined, or if the function
-      doesn't include/implement the missing class. So only set this entry,
-      if you really want to implement such a callback-function.
+      The callback specified is called when <function>unserialize</function>
+      attempts to use an undefined class. A warning appears if the specified
+      callback function is not defined, or if the callback function fails to
+      define the missing class.
