A compilation framework to allow coding web frontends in a modern style.

var EventEmitter = require('events').EventEmitter;

    this.on = false;
    this.ev = new EventEmitter();

    }).bind(this));
}

    this.ev.emit('on');
};

    if (this.on == true) {
        cb();
    } else {
        this.ev.on('on', cb);
