+// Create custom keycodes with arbitrary shifted and unshifted keys.
+// originally for dvorak on bepo. But used by beakl on qwerty now too.
+
+// Why?: Because the keycodes are actually defined on the computer. So
+// if you are trying to have dvorak, or beakl on bepo-fr, the shifted keys
+// are wrong. But, I want my dvorak, so this allows the pairing of keys into
+// a keycode that has shifted and non shifted behavior, outside of what the
+// locale map says on the computer.
+//
+// These are the keys for dvorak on bepo. column one is the keycode and mods for
+// the unshifted key, the second column is the keycode and mods for the shifted key.
+// GR is Good Range. It subtracts SAFE_RANGE from the keycode so we can make a
+// reasonably sized array without difficulties. The macro is for the constant declarations
+// the function is for when we use it.
+
+//make an alt_local_keys.def - see the example.
+// Include this file where you have your process_record_user function,
+// call process_alt_local_key inside your process_record_user.
