   7  * This is a tool that generate configuration file before compilation of Quarn
   8  * OS. Possible configuration options are read from external file and parsed.
   9  * Then there are shown menus in which user can adjust his own compilation of
  10  * the system. This tool uses ncurses, for computers without this library, there
  11  * is a less user-friendly shell script.
