+# open3.rb: Spawn a program like popen, but with stderr, too. You might also
+# want to use this if you want to bypass the shell. (By passing multiple args,
+# with IO#popen does not allow)
+#
 # Usage:
 #	require "open3"
 #
-#	in, out, err = Open3.popen3('nroff -man')
+#      stdin, stdout, stderr = Open3.popen3('nroff -man')
 #  or
 #	include Open3
-#	in, out, err = popen3('nroff -man')
-#
+#      stdin, stdout, stderr = popen3('nroff -man')
 
 module Open3
   #[stdin, stdout, stderr] = popen3(command);
