+\r
+  Console based on Win32 APIs. \r
+\r
+  This file attaches a SimpleTextIn protocol to a previously open window.\r
+  \r
+  The constructor for this protocol depends on an open window. Currently\r
+  the SimpleTextOut protocol creates a window when it's constructor is called.\r
+  Thus this code must run after the constructor for the SimpleTextOut \r
+  protocol\r
