A framework is goddamn useless. You know that right? Well, the framework provides you facilities. It is you who should actually use the features provided by the framework to create your application; and in that process sir, you are going to create more files. Of those files, there would be some files whose whole purpose is to be included elsewhere and such files are usually called as 'includes'. As such, the QCubed framework itself is contained in the includes directory of the installation.
