// This is an includefile containing the common
// stuff for using RoboCopy.
// To use, you must call RoboCopyInit().
// It creates the global, "g_robocopy" which contains the ActiveX object
// pointing to RoboCopy.
// When you are finished, you must call g_robocopy.UnRegister()
//
// You must have a "function [script]_js::OnEventSourceEvent(RemoteObj, DispID, cmd, params)"
// and filter messages to robocopy like this:
// if (g_robocopy == null || !g_robocopy.OnEventSource(arguments))
// {
//     do your processing here...
// }
//
//
// Aside from RoboCopyInit(), all RoboCopy function may throw exceptions - you must be prepared to handle this.
//
// If you wany copy status, override the following functions:
//     StatusStarted();
//     StatusFile();
//     StatusProgress(nPercent, nSize, nCopiedBytes);
//     StatusError();
//     StatusDone()
//     StatusMessage(nErrorCode, strErrorMessage, strRoboCopyMessage, strFileName)
