2.4 Why does Voyager use MUI? I *hate* MUI! MUI (Magic User Interface) is a program & API designed by Stefan Stuntz that allows users to configure nearly every apsect of the GUI of MUI programs. For devlopers, however, MUI allows much more freedom in the design of GUI's. Not only does it increase the efficiency with which the programmer can build a GUI, it provides a great deal of object-oriented tools for GUI maintenance. Without MUI, Voyager would not exist. If it *did* exist in some form, the executable would be many times larger, would require much more memory, and be far less efficient. [Oliver Wagner, Voyager Mailing List]. The benefit of MUI is that it is uses a series of *shared* libraries. Thus, if one program in your system has opened the MUI libraries, all programs that use them will use the SAME COPY of the library, thus saving memory. Otherwise, your mailer, your browser, your newsgroup reader, your telnet client, etc., would each have to have their own user-interface code and would take much more memory and hard-drive space. Among its other benefits, MUI is a way of consolidating the memory/space usage of a variety of programs. Not only does it make life easier on users by providing the ability to customize every aspect of their programs, it makes life *MUCH* easier for programmers. Oliver Wagner, the programmer of Voyager, has stated on several occasions that Voyager WOULD NOT EXIST without MUI. So, the real question is: do you like Voyager more than you hate MUI?
