This class implements the Foundation framework's
exception-handling
system. Exceptions are used in Cocoa as a mechanism to deal with
special conditions in the execution of a program that may require
special handling. Clients can use NSException
objects to raise exceptions (creating a special condition), as well
as to retrieve information about an exception. For details on
exception handling, see Chapter 2.
