+
+This is the ocaml tutorial example.  It assumes that you've already
+built and installed the thrift ocaml runtime libraries in lib/ocaml.
+
+To compile this, you will need to generate the Thrift sources for
+ocaml in this directory (due to limitations in the OASIS build-tool):
+
+  % thrift -r --gen ocaml ../tutorial.thrift
+  % oasis setup
+  % make
+
+This will produce two executables Calc{Server,Client}.<type> where
+<type> is one of "byte" or "native", depending on your ocaml
+installation.  Just run the server in the background, then the client
+(as you would do for the C++ example).
