* @brief Represents a file notification
*
* This class allows to watch for events happening to files.
* It uses the dnotify kernel interface which is a very efficient signalling interface.

/**
* This static function calls a slot when an event with @a type happens to file @a path.
*
* It is very convenient to use this function because you do not need to
* bother with a timerEvent or to create a local QTimer object.
*
* Example:
* <pre>
*
* #include <opie2/oapplication.h>
* #include <opie2/onitify.h>
* using namespace Opie::Core;
*
* int main( int argc, char **argv )
* {
* OApplication a( argc, argv, "File Notification Example" );
* OFileNotification::singleShot( "/tmp/quit", &a, SLOT(quit()), Create );
* ... // create and show your widgets
* return a.exec();
* }
+ * </pre>
*
* This sample program automatically terminates when the file "/tmp/quite" has been created.
*
*
* The @a receiver is the receiving object and the @a member is the slot.
