+# ui_remote.py - naive script to poke and prod the altimeter firmware over
+# GDB/MI. Useful for rapid UI development/testing, all while probably not being
+# strictly threadsafe. We're not triggering an ISR on the remote, so PC could
+# already be in the middle of an ISR when we fire a UI event, which should
+# never be allowed to happen in normal use.
+# Useful nonetheless.
+#
+# FIXME allow smarter queueing of UI events in this script so they can be
+#       batched into the same (slow) interrupt-and-continue window.
