+General
+-------
+This document details how to build and install the Cdk library. The first thing
+you should know is what compile options you may require. I have had the 
+fortunate luck of being able to compile this library on the following
+platforms:
+	* Sun/OS 4.1.*
+	* Solaris 2.3/2.4/2.5/2.5.1/2.6
+	* AIX 3.2.* (and even AIX 4.1 but there is no mention of this in the
+                    makefile. Sorry.)
+	* HPUX 9.* (and even HPUX 10.* but there is no mention of this in the
+                    makefile. Sorry.)
+	* Linux (all sorts Slackware, BSD, and Redhat)
+
+Building
+--------
+To build the library cd into the Cdk distribution directory and follow 
+the following steps:
+
+1) Run configure. This will create a Makefile with a default 
+	install directory root of /usr/local. If you want to 
+	change the default install directory use the --prefix 
+	command line argument on configure. For example, if you
+	want to install under /export/local instead, run the command:
+	./configure --prefix="/export/local"
+
+2) Type make. This will make the library, the example binaries
+	and the demonstration binaries.
+
+3) Type make install. This will install the CDK distribution. Look
+	at step 1 if you want to install other than /usr/local.
+
+4) Start to play. :)
