//		Copying a file

//------------ 
// Notes
//	- You must have a file on your disk that contains at least two 
//		lines of text. You can use the  file "Americas.Most.Wanted"
//		created by the program for class Chapter3_8_0.
//	- Compiling this program generates the following warning which
//		may be ignored:
//			'CopyFile.java uses a deprecated API.  Recompile 
//			with "-deprecation"	for details.'
