 Without an explicit path, it processes the standard input.  Given a file,
 it operates on that file; given a directory, it operates on all .go files in
 that directory, recursively.  (Files starting with a period are ignored.)
+By default, gofmt prints the reformatted sources to standard output.
 
 Usage:

 The flags are:
 
+	-d
+		Do not print reformatted sources to standard output.
+		If a file's formatting is different than gofmt's, print diffs

 	-l
-		just list files whose formatting differs from gofmt's;
-		generate no other output unless -w is also set.
+		Do not print reformatted sources to standard output.
+		If a file's formatting is different from gofmt's, print its name

 	-r rule
-		apply the rewrite rule to the source before reformatting.
