+Stuff to do before 0.6.4 release:
+=================================
+
+* integrate filters into --buttonmap and --axismap:
+
+  --buttonmap X^toggle:autofire=B
+  --axismap Y1^relative
+
+  main purpose: allow to make shift a toggle button
+
+* bug: when shifting the last axis state sticks even when they key was released
+
+Figure out a way to load custom keymaps:
