as a result all downloaded and builded components (except already installed on system) will be 
included to final package. It is better to install specific drivers and software before run,
like gcc make and so on. This script utilize arch linux packages system, and it uses 
3rd party PKGBUILDs from AUR for required components and for ffmpeg-full-amd...
Final license of rezulted package is complex and nonfree.
