Module Name:
message.hxx
Abstract:
The MESSAGE class provides a dummy implementation of a message displayer
class. Message displayers are meant to be used by applications to
relay information to the user. Many functions will require a 'MESSAGE'
parameter through which to relay their output.
This particular implementation of this concept will do nothing. It
will be used by users who do not wish to have any output from their
applications.
Additionally, this class serves as a base class to real implementations
of the virtual methods.
