+						  HOT RELOADING DEMO
+
+This is a simple demo of hot code reloading in C on Linux. Internally,
+it uses the POSIX dlopen() family of functions for dynamic loading and
+the Linux inotify API for watching the filesystem.
+
+To build, run the build.sh script.  When running the demo, you must
+specify the build directory in LD_LIBRARY_PATH:
+
+	  LD_LIBRARY_PATH=build build/demo
+
+The demo will repeatedly print out the message returned by getmsg(),
+defined in mod.c -- if getmsg() is modified to return a different
+message and recompiled, the change will be loaded in running program.
