+
+VERSION
+-------
+0.1 2010/08/23
+ implemented for macway modified.
+ It works as normal keyboard now.
+
+
+TODO
+----
+modulization
+ clean source
+debouncing
+anti-ghost
+keymap layer
+ key combination switch
+ toggle siwtch
+ HHKB like cursor etc.
+setting menu(wizard)
+ debug console
+ keymap setting
+ matrix display
+HHKB support
+Trackpoint(PS/2) support
+ Thinkpad keyboard support
