+ * 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.
