/*

|
|
* 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.
