+# This script can be used to generate some unregisterised .hc files
+# for bootstrapping GHC on a new/unsupported platform.  It involves a
+# two-stage bootstrap: the first stage builds an unregisterised set of
+# libraries & RTS, and the second stage builds an unregisterised
+# compiler.  
+
+# Take the .hc files from the libraries of stage 1, and the compiler
+# of stage 2, to the target system and bootstrap from these to get a
+# working (unregisterised) compiler.
