-//    The module loaded is run inside a function, with one argument, global which
-//    points to the global context.  So global.FN is the same as FN (as long as a
-//    version of FN does not exist in local scope).
-//
-//    The module should return its interface at the end of the script.  The basic
-//    pattern for a module is:-
-//
-//    var module = { ... };
-//    return module;
-//
-//    Or:-
-//
-//    return function() {
-//    }
-//
-//    The appname argument causes <appname>.js to be loaded. The interface returned
-//    must define main = function(args) {}, which is called once the module is
-//    loaded.
