+#!/bin/bash
+
+# This script performs an automated self-hosted build of dragonegg.  In
+# other words it builds dragonegg, then builds GCC and LLVM with dragonegg,
+# then uses those and dragonegg to rebuild dragonegg.  It does this a couple
+# of times until it reckons you must be fed up.  At which point it checks
+# that the dragonegg plugin is not changing at each iteration.
+#
+# This is all extreme overkill if all you want to do is try out dragonegg!  If
+# that's your goal then I suggest you consult the README file one directory up.
