/*
* File: main.h
* ------------
* This file renames the <code>main</code> method in the client's
* program to <code>Main</code>, thereby allowing a custom
* <code>main</code> method in the libraries to take control
* before passing control back to the client program. The main macro
* also defines a function getMainFlags that returns an int whose bits
* indicate which of the various interfaces have been loaded by this
* definition of main.
*
* Note: This file can be loaded more than once and must therefore
* check to see what has already been defined.
