// <synopsis>
// This module provides the exception handling mechanism used in AIPS++.
// It allows the user to define new exception types and to <src>throw</src>,
// <src>catch</src>, and <src>rethrow</src> these exceptions. The interface
// to this exception handling mechanism is very similary to the ANSI standard
// exceptions. This will make it easy to switch when the time comes.
//
// This module supplies several <linkto file="Error.h">common exception types </linkto>.
// These provide examples for creating new errors.
//
// At some point, this exception mechanism will probably be replaced with
// compiler supported exceptions.
// </synopsis>
//
// <example>
// <em>This example shows how a more specific exception can be caught as
// a more general exception:</em>
// <srcblock>
//     #include <casa/Exceptions.h>
//     #include <iostream>
//     main() {
//         try {
//             throw(indexError<int>(5,"Dummy error"));
//         } catch (IndexError xx) {
//             cout << "caught IndexError" << endl;
//         } 
//     }
// </srcblock>
// </example>
// </module>
