// 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.
