+This is a short description on the use of the client demo,
+a client that initiates and uses a random number generator
+that lies on a C-server.
+
+Instructions.
+
+1) 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 ( generates and compiles all code )
+
+ server ( starts the c-server )
+
+
+ To test the c-client against the c-server start a new terminal window and type :
+ --------------------------------------------------------------------------------
+
+ client ( calls the server )
+
+
+ To test the erlang-client against the c-server start a new terminal window and type :
+ -------------------------------------------------------------------------------------
+
+
+ erl -sname client -setcookie flash ( start erlang )
+
+ client:init(1,2,3). ( initiates the random generator )
+
+ client:produce(). ( calls the random generator )
