00045 // <synopsis>
00046 // This module provides the exception handling mechanism used in AIPS++.
00047 // It allows the user to define new exception types and to <src>throw</src>,
00048 // <src>catch</src>, and <src>rethrow</src> these exceptions. The interface
00049 // to this exception handling mechanism is very similary to the ANSI standard
00050 // exceptions. This will make it easy to switch when the time comes.
00051 //
00052 // This module supplies several <linkto file="Error.h">common exception types </linkto>.
00053 // These provide examples for creating new errors.
00054 //
00055 // At some point, this exception mechanism will probably be replaced with
00056 // compiler supported exceptions.
00057 // </synopsis>
00058 //
00059 // <example>
00060 // <em>This example shows how a more specific exception can be caught as
00061 // a more general exception:</em>

00068 //         } catch (IndexError xx) {
00069 //             cout << "caught IndexError" << endl;
