+This is a short description on the use of the c-client demo,
+a client that initiates and uses a random number generator
+that lies on an Erlang-genserver.
+
+Instructions.
+
+1) On Makefile :
+ * Modify the OTPROOT variable on the Makefile to point
+ to the root for your erlang instalation.
+ * Modify IC and Erl_Interface versions to agree your
+ OTP version.
+
+2) Type "make" to build the example.
+
+
+3) Start erlang with the options
+ -setcookie <Some Cookie> -sname <SomeNodeName>
+
+ In this example you should use :
+
+ erl -setcookie flash -sname babbis
+
+
+4) On the erlang shell type :
+ --------------------------
+
+ rmod_random:oe_create([],{local,rmod_random_impl}). ( initializes the server )
+
+ or
+
+ test:start().
+
+
+ Then start a new terminal window and type :
+ -------------------------------------------
+
+ client ( calls the client )
+
+
+
