+In the event you want to include ghc-compiled code as part of another
+(non-Haskell) program, the RTS will not be supplying its definition of
+<tt/main()/ at link-time, you will have to. To signal that to the
+driver script when linking, use <tt/-no-hs-main/.
+
+Notice that since the command-line passed to the linker is rather
+involved, you probably want to use the ghc driver script to do the
+final link of your `mixed-language' application. This is not a
+requirement though, just try linking once with <tt/-v/ on to see what
+options the driver passes through to the linker.
