+
+The gofmt program is a formatter for Go programs.
+
+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.)
+
+Usage:
+	gofmt [flags] [path ...]
+
+The flags are:
+
+	-l
+		just list files whose formatting differs from gofmt's; generate no other output
+		unless -w is also set.
+	-w
+		if set, overwrite each input file with its output.
+	-spaces
+		align with spaces instead of tabs.
+	-tabwidth=8
+		tab width in spaces.
+	-align=true
+		align columns.
+
+Debugging flags:
+
+	-trace
+		print parse trace.
+	-comments=true
+		print comments; if false, all comments are elided from the output.
