+// If you wish to you use these macros for emulating exceptions on
+// platforms which lack native exception support, you need to do the
+// following:
+// 1. Define a class Exception. You can name it as you please. This class
+//    should be at the root of the inheritance hierarchy of all the
+//    exceptions used in your application. It should support at a minimum
+//    the following methods:
+//    a) _downcast () - Which allows narrowing of the base exception type to a
+//       derived type.
+//    b) _raise() - Which does what ???? XXX: FIXME
+//
+// 2. Define a class Environment. You can name it as you please. This class
+//    is an exception holder. This class is always on the stack. It should
+//    support at a minimum the following methods:
+//      a) exception() - Which returns the Exception held in the current
+//         Environment.
+//      b) exception (Exception* foo) - Which replaces/sets the Exception
+//         held in the current Environment with foo.
+//      b) clear() - Which resets a particular instance of Environment.
+//      c) A copy constructor and an assignment operator.
+//
+//  Note that the above description assumes that you use the following
+//  macros only within a particular domain. For example, if your
+//  application has to interoperate across domains, then you need to define
+//  an exception adapter to translate exceptions from one domain to
+//  exceptions in the other. Please refer to Stroustrup's book on how to do
+//  this. If your use case is this complex, you would be better off with
+//  going with native exceptions rather than emulated exceptions, though
+//  the macros should still work if you defined your adapter class as
+//  ACE_EXCEPTION_TYPE.
+

+// in/out of each function that can throw an exception. The type of the
