+This keymap attempts to match the Kinesis Contoured (aka Advantage) default
+layout as closely as possible. See
+http://www.kinesis-ergo.com/wp-content/uploads/2013/06/advantage_layout_win.pdf
+
+Apart from the obvious mappings, this keymap also:
+
+* removes the dual-purpose momentary layer/normal keys: Z, /, and Grv;
+  because the author--coming from a Kinesis keyboard--finds the delays and
+  accidental modifiers to be more disconcerting than helpful.
+
+* puts Esc in the bottom left since there's no place for it in the top
+  left to match the Kinesis.
+
+* changes the bottom-right key into an L2 toggle since there's otherwise no
+  way to get to L2.
+
+* adds PrScr, ScrLk and Pause to the L1 keymap, down the left side, since
+  they're present on the Kinesis but not available in the default
+  ergodox_ez keymap.
