// Unfortunately, this doesn't use Qt as well as I would like,
// primarily because NetHack is fundamentally a getkey-type program
// rather than being event driven (hence the ugly key and click buffer)
// and also because this is my first major application of Qt.  
// 
// The problem of NetHack's getkey requirement is solved by intercepting
// key events by overriding QApplication::notify(...), and putting them in
// a buffer.  Mouse clicks on the map window are treated with a similar
// buffer.  When the NetHack engine calls for a key, one is taken from
// the buffer, or if that is empty, QApplication::exec() is called.
// Whenever keys or clicks go into the buffer, QApplication::exit()
// is called.
//
// Another problem is that some NetHack players are decade-long players who
// demand complete keyboard control (while Qt and X11 conspire to make this
// difficult by having widget-based focus rather than application based -
// a good thing in general).  This problem is solved by again using the key
// event buffer.
//
// Out of all this hackery comes a silver lining however, as macros for
// the super-expert and menus for the ultra-newbie are also made possible
// by the key event buffer.
//

// This includes all the definitions we need from the NetHack main
// engine.  We pretend MSC is a STDC compiler, because C++ is close
// enough, and we undefine NetHack macros which conflict with Qt
// identifiers (now done in qt_pre.h).
