// Bootstrap code, basic module loading functionality
/////////////////////////////////////////////////////////////////////////////////

//
//    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.
